Purposive behaviorism

Purposive behaviorism is a school of psychological thought developed by American psychologist Edward C. Tolman in his 1932 book Purposive Behavior in Animals and Men, which emphasizes that animal and human behavior is inherently goal-directed and purposive, involving cognitive processes such as expectancies and mental representations, rather than being solely a product of stimulus-response associations as in classical behaviorism.^[1] Tolman's theory, also known as molar behaviorism, treats behavior as holistic units or "molar" wholes—such as an organism navigating a maze to reach a goal—rather than breaking it down into molecular reflexes or isolated S-R connections promoted by earlier behaviorists like John B. Watson and Ivan Pavlov.^[2] Central to this approach is the concept of purpose, where behavior is driven by the anticipation of achieving specific ends, as evidenced in Tolman's experiments with rats learning efficient paths in mazes without immediate rewards, demonstrating a preference for "least effort" routes.^[1] Unlike classical behaviorism, which required reinforcement for learning, Tolman argued that learning could be latent, occurring through exploration and forming internal cognitive structures even if not immediately expressed in behavior, as shown in his 1930 study with C.H. Honzik where rats improved performance only after rewards were introduced, suggesting prior cognitive acquisition.^[2] A key innovation in purposive behaviorism is the idea of cognitive maps, mental frameworks that organisms build to represent their environment's spatial relationships and possible actions, allowing flexible adaptation to new situations without trial-and-error reinforcement. Tolman described this as involving means-end expectancies and sign-gestalt expectations, where environmental cues (signs) signal pathways to goals, enabling purposeful navigation.^[1] He further incorporated demands as the organism's internal needs or urges—such as hunger or avoidance of danger—that drive behavior towards specific goals, interacting with environmental cues to enable attainment.^[1] These elements positioned purposive behaviorism as a bridge between strict behaviorism and emerging cognitive psychology, using intervening variables (e.g., cognitions) to explain behavior objectively while avoiding unobservable introspection.^[2] Tolman's work, conducted primarily at the University of California, Berkeley, influenced later theories by demonstrating through rat maze studies that learning involves building knowledge structures rather than mere habit formation, paving the way for cognitive revolutions in psychology during the mid-20th century. Despite criticisms for its abstractness compared to more mechanistic alternatives, purposive behaviorism highlighted the limitations of reductionist approaches and underscored the role of intention and foresight in adaptive behavior.^[2]

Introduction

Definition and origins

Purposive behaviorism represents a variant of behaviorism that integrates goal-directed, or purposive, actions into the study of behavior, while incorporating cognitive elements such as expectancies to explain learning and motivation without resorting to the internal mental states emphasized in introspectionist approaches.^[3] Developed within the broader behaviorist tradition, it posits that behavior is not merely reflexive but functional, involving an adjustment between the organism and its environment to achieve specific ends.^[4] This framework maintains the objective, observable focus of behaviorism but extends it to account for purpose as an inherent property of behavior itself, observable through patterns of action rather than inferred from subjective reports.^[5] The theory originated in the early 20th century as a critique of the dominant stimulus-response (S-R) model of classical behaviorism, which reduced behavior to mechanical chains of responses to stimuli without addressing motive or goal orientation.^[3] Edward C. Tolman, an American psychologist, first articulated the core ideas of purposive behaviorism in his 1925 paper "Behaviorism and Purpose," where he argued for a behaviorism that could accommodate purpose without invoking mentalism.^[5] Tolman expanded this foundation in his seminal 1932 book Purposive Behavior in Animals and Men, systematically outlining the theory as a "molar" approach to psychology, thereby establishing it as a distinct school within behaviorism during the 1920s and 1930s.^[1] A central distinction in purposive behaviorism lies in its adoption of a molar perspective on behavior, which treats actions as holistic, integrated units oriented toward goals, in opposition to the molecular view that breaks behavior down into atomic S-R connections.^[4] In the molar framework, behavior is seen as pragmatic and adaptive, encompassing the entire organism's effort to alter its relation to the environment for purposive ends, rather than a series of isolated physiological responses.^[1] This shift allowed Tolman to bridge behaviorist empiricism with cognitive insights, influencing subsequent developments in learning theory.^[3]

Core principles

Purposive behaviorism posits that behavior is inherently purposive, meaning it is directed toward achieving specific goals through anticipation of outcomes rather than automatic, mechanical responses to stimuli.^[6] This principle emphasizes that organisms engage in actions with an implicit understanding of ends, guided by internal expectancies that forecast the results of their behaviors, thereby introducing a teleological element into the analysis of observable actions.^[6] Central to this framework is Tolman's emphasis on cognition, which asserts that both animals and humans develop internal representations, such as expectancies or cognitive maps, that inform and direct behavior.^[6] These cognitive elements challenge strict associationist views by positing that learning involves the formation of meaningful connections between signs (stimuli) and goals, rather than simple stimulus-response bonds.^[6] For instance, an organism's behavior is shaped not merely by immediate environmental cues but by anticipated relations within its broader field of experience.^[6] The approach adopts molar behaviorism, analyzing behavior as integrated whole acts—such as navigating toward food—rather than deconstructing it into discrete stimulus-response units.^[6] Key components include demand, which reflects the organism's drive to minimize effort in achieving goals; means-end readiness, the capacity to recognize and utilize pathways to objectives; and performance variables, factors like motivation and environmental conditions that influence the execution of learned behaviors.^[6] This holistic perspective treats behavior as a unified process oriented by these interrelated elements.^[6] Finally, purposive behaviorism rejects the primacy of reinforcement in learning, arguing instead that cognitive restructuring—through the acquisition of sign-gestalt expectancies—occurs independently of immediate rewards.^[6] Learning thus proceeds via insightful reorganization of environmental relations, rendering trial-and-error mechanisms insufficient for explaining complex, goal-directed adaptations.^[6]

Historical context

Roots in classical behaviorism

Classical behaviorism emerged in the early 20th century as a reaction against introspective methods in psychology, emphasizing the study of observable behavior over subjective mental states. John B. Watson's 1913 manifesto, "Psychology as the Behaviorist Views It," formalized this approach by defining psychology as a purely objective experimental branch of natural science, akin to physics or chemistry, with the goal of predicting and controlling behavior while rejecting introspection and consciousness as unscientific.^[7] Watson argued that mentalistic concepts like thoughts and feelings were unnecessary, advocating instead for the analysis of stimulus-response (S-R) associations derived from environmental stimuli and observable reactions.^[8] This framework was heavily influenced by Ivan Pavlov's work on classical conditioning in the 1890s and 1900s, where neutral stimuli, through repeated pairing with unconditioned stimuli, elicited conditioned responses, establishing foundational S-R learning mechanisms without reference to internal cognition.^[9] A key precursor to classical behaviorism was Edward Thorndike's connectionism, introduced in his 1898 dissertation on animal intelligence. Thorndike proposed the Law of Effect, stating that behaviors followed by satisfying consequences are more likely to be repeated and strengthened, while those followed by discomfort are weakened, thereby forming S-R bonds through trial-and-error learning.^[10] This principle shifted focus from mere reflexes to consequences shaping connections between stimuli and responses, influencing later behaviorists by providing an empirical basis for habit formation. However, Thorndike's model retained a strict associationist view, prioritizing mechanical linkages over any purposive elements in behavior.^[11] The S-R model of classical behaviorism, while parsimonious, faced limitations in accounting for adaptive behaviors in complex environments, as it reduced all learning to direct stimulus-response chains without mechanisms for flexibility or goal orientation. Critics noted that this approach overlooked how organisms navigate novel situations or select actions based on anticipated outcomes, rendering it inadequate for explaining insightful or variable responses beyond rote associations.^[12] For instance, simple S-R pairings struggled to address phenomena like detour problems or varying reinforcement schedules that demanded behavioral adjustment.^[13] By the 1920s, these shortcomings prompted a transition to neobehaviorism, which relaxed Watsonian positivism by incorporating hypothetical constructs—such as drives or expectancies—to mediate between stimuli and responses, allowing for more nuanced explanations of learning while remaining committed to empirical verification. This shift, evident in works from the late 1920s onward, laid the groundwork for purposive variants by enabling the modeling of goal-directed behavior without invoking unobservable mentalism.^[14]

Tolman's development of the theory

Edward C. Tolman was born on April 14, 1886, in West Newton, Massachusetts, into an upper-middle-class family with strong reformist values. He earned a B.S. in electrochemistry from the Massachusetts Institute of Technology in 1911 and a Ph.D. in philosophy and psychology from Harvard University in 1915, where he was influenced by philosophers William James and Ralph Barton Perry, as well as psychologist Robert Yerkes.^[15] In 1918, Tolman joined the faculty at the University of California, Berkeley, as an instructor in psychology, a position he held until his death in 1959, rising to full professor in 1926.^[15] During the 1920s, Tolman began developing his ideas on purposive behaviorism, drawing from Gestalt psychology—particularly the works of Kurt Koffka and Kurt Lewin—and American pragmatism, which emphasized functional and goal-directed aspects of behavior over strict stimulus-response mechanisms.^[15] In his 1920 paper "Instinct and Purpose," he introduced the concept of purposive behavior as an alternative to mechanistic instinct theories.^[15] This culminated in his seminal 1922 article "A New Formula for Behaviorism," published in Psychological Review, where he critiqued John B. Watson's molecular behaviorism for its reductionist focus on reflexes and proposed a molar approach that incorporated purpose (denoted as "θ" or "theta") as an essential intervening variable in the behavior equation: B = f(S, θ), allowing for goal-oriented actions without invoking mentalism.^[15] In the 1930s, Tolman's theory evolved by integrating elements of field theory, emphasizing the organism's perception of the environmental field and its expectancies within it, as detailed in his major work Purposive Behavior in Animals and Men (1932).^[15] During World War II, he applied his framework to practical issues, analyzing soldier motivation and social control mechanisms, outlined in Drives Toward War (1942).^[15] Postwar, in the late 1940s, Tolman shifted emphasis toward cognitive processes, introducing the concept of cognitive maps in his 1948 paper "Cognitive Maps in Rats and Men," which portrayed learning as the formation of spatial and relational knowledge structures rather than mere associations.^[15] Tolman's institutional contributions at Berkeley included establishing a dedicated rat laboratory in the 1920s for systematic learning experiments, which became a hub for empirical research on animal behavior.^[15] He also mentored a generation of influential students, including B. F. Ritchie and David Krech, fostering advancements in cognitive and social psychology through collaborative projects like the 1946 study on place versus response learning.^[16]^[15]

Theoretical framework

Intervening variables

In purposive behaviorism, intervening variables are hypothetical constructs inferred from observable behavior to explain the relationship between stimuli and responses, forming the core of the stimulus-organism-response (S-O-R) framework.^[17] These variables, such as hunger or expectancy, are not directly observed but are posited as internal states within the organism that mediate behavioral outcomes, allowing for a more nuanced understanding beyond simple stimulus-response associations.^[18] The role of intervening variables in Tolman's theory enables neobehaviorists to incorporate cognitive elements scientifically without resorting to introspective mentalism, bridging observable environmental inputs and behavioral outputs.^[19] For instance, the "cognitive map"—a mental representation of spatial relationships—is treated as an intervening variable that accounts for navigational behavior in maze experiments, where rats demonstrate goal-directed choices based on inferred environmental knowledge rather than trial-and-error alone.^[18] This approach contrasts with classical behaviorism by emphasizing organismic processes that guide purposive action. Tolman formalized the use of intervening variables in his 1935 paper "Psychology versus Immediate Experience," defending them against strict empiricists who demanded direct observation of all psychological phenomena, arguing instead that such constructs are essential for objective causal explanations in psychology.^[17] He further operationalized them in 1938's "The Determiners of Behavior at a Choice Point," where variables like hunger (as "demand") are quantified through performance curves plotting behavioral efficiency—such as speed or choice accuracy—against drive levels manipulated by factors like hours since feeding.^[18] The advantages of intervening variables lie in their ability to predict and systematize behavior empirically while avoiding unverifiable mentalistic claims, fostering testable hypotheses within a behaviorist paradigm.^[19] In contrast, B.F. Skinner rejected such variables in his 1950 critique "Are Theories of Learning Necessary?," viewing them as unnecessary theoretical distractions that obscure direct functional analyses of environmental contingencies on behavior.^[20]

Expectancy and purpose in behavior

In purposive behaviorism, expectancy refers to an internal cognitive anticipation of the relations between environmental stimuli and outcomes, formed through prior learning experiences. This concept posits that organisms develop expectations such as "if I turn left, food follows," which guide behavioral choices by providing a mental framework for predicting consequences without requiring immediate reinforcement.^[21] Tolman described expectancy as a "sign-gestalt-expectation," a holistic cognitive structure linking a sign-object (a stimulus or means) to a signified object (a goal or end) through learned relations of direction and distance.^[21] Purpose manifests in behavior as goal-directed "means-end" sequences, where organisms select actions based on their perceived relevance to achieving desired outcomes. Central to this is the notion of "demand," a motivational state arising from physiological needs that cathects (energizes) specific goals, making them salient in the organism's cognitive field.^[21] Complementing demand is the "sign-Gestalt," the perceptual organization of cues that signal potential outcomes, enabling the organism to interpret environmental signs as pathways to ends. Together, these elements drive adaptive behavior by orienting actions toward purposes, rather than mere reflexive responses.^[3] The theoretical model underlying these concepts is the S-E-R (stimulus-expectancy-response) framework, which positions expectancy as a mediating cognitive process between environmental stimuli and behavioral responses, facilitating flexible adaptation. In this schema, stimuli activate expectancies that evaluate multiple response options, leading to the selection of the most goal-relevant path; for instance, in detour problems, an organism might anticipate alternative routes around obstacles based on prior sign-gestalt formations, demonstrating problem-solving without trial-and-error.^[21] This contrasts with classical S-R models by emphasizing cognitive mediation for purposive efficiency.^[22] Purposive behaviorism critiques strict reinforcement theories by arguing that purpose emerges from cognitive processes like expectancy formation and mental mapping, rather than solely from reward contingencies, allowing for vicarious trial-and-error—where organisms mentally simulate outcomes before acting. This enables adaptive flexibility, as behavior is directed by anticipated goal relations rather than habitual associations strengthened only by drives or reinforcements.^[21]

Key concepts and experiments

Cognitive maps

Cognitive maps represent a central concept in purposive behaviorism, referring to internal, cognitive representations of spatial environments that enable organisms to navigate flexibly without relying on fixed stimulus-response chains. Edward C. Tolman introduced the idea in his seminal 1948 paper, describing them as "something like a field map of the environment" established in the organism's brain during learning, which allows for the apprehension of overall layouts rather than mere sequential paths.^[23] These mental models permit goal-directed behavior, such as taking shortcuts or detours, by integrating spatial relationships into a holistic structure independent of specific routes. Cognitive maps form through exploratory experiences and processes like latent learning, where organisms acquire knowledge without immediate reinforcement, building these representations over time. In purposive behaviorism, exploration drives the construction of such maps by allowing animals to sample environmental cues, leading to an inferred understanding of the space that manifests later when needed for navigation.^[23] For instance, non-rewarded trials in mazes enable rats to develop these maps, which then support efficient problem-solving upon the introduction of rewards, as integrated with latent learning mechanisms. Key evidence for cognitive maps came from a 1946 experiment by Tolman, Ritchie, and Kalish, discussed in the 1948 paper, using an elevated maze with rats. In the study, rats were initially trained to run from a starting point across a circular table to a food box via a guided path; afterward, the maze was reconfigured into a "sunburst" pattern with 12 radiating arms from the center. The rats, having been trained on the original path, consistently chose arm No. 6 (pointing near the food box's location, about 4 inches off) or arm No. 1 (perpendicular to it), with initial exploration of multiple arms before committing to one, rather than random wandering. This behavior indicated that the rats had formed a comprehensive cognitive map, inferring the goal's position and selecting novel paths accordingly, rather than depending on learned sequences.^[23] The implications of cognitive maps extend purposive behaviorism by demonstrating cognitive processes in animals, challenging strict behaviorist views and suggesting that even rats possess representational thinking akin to human spatial cognition. Tolman argued that these maps facilitate adaptive navigation and problem-solving, with broader, more flexible representations emerging under normal conditions to support planning and goal attainment. In humans, this concept parallels mental modeling for route-finding and strategic decision-making, underscoring the role of internal expectancy in purposeful action.^[23]

Latent learning

Latent learning refers to the acquisition of knowledge or skills without immediate reinforcement, where the learned behavior only becomes apparent when a suitable incentive is introduced.^[24] This concept, central to purposive behaviorism, emphasizes that organisms can form internal representations of their environment through exploration alone, rather than relying solely on trial-and-error reinforced by rewards or punishments.^[25] In a seminal experiment, Edward C. Tolman and Charles H. Honzik (1930) tested latent learning using three groups of rats in a complex 14-unit T-maze designed to measure errors (blind entries into incorrect alleys) over multiple trials.^[25] The experimental group received no food reward for the first 10 days, allowing free exploration; from day 11 onward, food was placed at the goal box. A continuously rewarded control group received food from day 1, while a never-rewarded control group explored without any incentive throughout. Results showed that the experimental group's error rate remained high during the initial unrewarded phase (averaging around 150 errors by day 10), similar to the never-rewarded group, but dropped sharply to under 50 errors on day 11—outperforming the continuously rewarded group, which had gradually decreased errors to about 60 by that point.^[25]^[24] Tolman and Honzik interpreted these findings as evidence that the rats in the experimental group had acquired a cognitive understanding of the maze during the unrewarded explorations, storing this knowledge latently until the introduction of reward motivated its expression.^[24] This sudden performance improvement indicated the formation of expectancies—anticipations of environmental outcomes—rather than incremental strengthening of stimulus-response habits through reinforcement.^[25] Such latent processes underpin the development of cognitive maps, as briefly evidenced by the rats' efficient navigation post-reward.^[26] Theoretically, latent learning challenged Edward Thorndike's Law of Effect, which asserted that learning occurs only through the strengthening of connections between stimuli and responses via satisfying consequences.^[27] By demonstrating that knowledge could accumulate without reinforcement and manifest abruptly when incentives aligned with goals, Tolman supported a purposive framework where behavior is directed by internal cognitive processes and exploratory drives, shifting focus from mechanical habit formation to goal-oriented cognition.^[24]

Influence and legacy

Impact on cognitive psychology

Purposive behaviorism, developed by Edward C. Tolman, played a pivotal role in bridging classical behaviorism and the emerging cognitive paradigm during the mid-20th century. By introducing concepts such as cognitive maps and latent learning, Tolman's framework emphasized internal mental processes like expectancies and goal-directed representations, challenging the strict stimulus-response focus of earlier behaviorists.^[28] This approach positioned purposive behaviorism as a key precursor to the cognitive revolution of the 1950s and 1960s, where psychology shifted toward investigating unobservable cognitive mechanisms.^[29] Noam Chomsky's influential 1959 critique of B.F. Skinner's Verbal Behavior further accelerated this transition by exposing the limitations of radical behaviorism in explaining complex phenomena like language acquisition.^[30] Ulric Neisser's 1967 book Cognitive Psychology formalized this shift, synthesizing advances in mental processes and explicitly building on Tolman's foundational ideas about spatial cognition and learning without immediate reinforcement.^[31] The theory's applications extended to animal cognition, where Tolman's demonstrations of rats forming internal representations of mazes inspired subsequent research in ethology and spatial navigation, underscoring how animals use cognitive structures to adapt to environments beyond simple conditioning.^[32] In human learning theories, purposive behaviorism influenced models emphasizing meaningful integration of knowledge, such as those promoting goal-oriented comprehension over rote memorization, by highlighting how expectancies shape behavioral outcomes.^[33] These ideas fostered a broader understanding of learning as an active, representational process, paving the way for cognitive approaches that view the mind as actively constructing knowledge from environmental cues. Tolman's emphasis on cognitive maps left a lasting legacy in education, informing curriculum designs that leverage mental representations to enhance spatial and conceptual navigation. For instance, cognitive maps are now used in online learning environments to guide students through resources, linking themes and materials to promote self-managed exploration and skill development, directly drawing from Tolman's 1948 conceptualization.^[34] Contemporary studies on GPS navigation echo this legacy, revealing that reliance on turn-by-turn directions impairs hippocampal engagement and cognitive map formation, while active sensory cues—such as auditory beacons—enhance spatial learning in ways reminiscent of Tolman's exploratory rat experiments.^[35] Despite its influence, purposive behaviorism faced criticisms for its heavy reliance on rat maze models, which limited generalizability to human cognition and complex real-world behaviors, as humans often employ simpler navigational strategies rather than comprehensive maps.^[24] By the 1970s, these ideas were refined and integrated into information-processing models, which portrayed the mind as a computational system handling inputs, storage, and outputs, incorporating Tolman's cognitive elements into broader frameworks of memory and decision-making.^[32] This synthesis helped solidify cognitive psychology's dominance, transforming purposive behaviorism from a fringe perspective into a foundational component of modern mental science.^[33]

Comparisons with other theories

Purposive behaviorism, developed by Edward C. Tolman, diverges from classical behaviorism—exemplified by John B. Watson and Ivan Pavlov—in its incorporation of cognitive mediators to explain behavior. While classical behaviorism adheres strictly to a stimulus-response (S-R) framework, emphasizing observable associations without reference to internal states, Tolman's approach introduces intervening variables such as expectancies and cognitive maps to account for goal-directed actions that cannot be reduced to simple reflexes.^[36] This allows purposive behaviorism to explain phenomena like insight and problem-solving without relying solely on immediate reinforcement, contrasting with Pavlov's classical conditioning, which focuses on involuntary responses to stimuli, and Watson's objective study of behavior as mechanistic chains.^[37]^[1] In comparison to B.F. Skinner's radical behaviorism, Tolman's theory employs intervening variables to bridge environmental stimuli and behavioral outcomes, whereas Skinner deliberately avoids such internal constructs, insisting that explanations remain operational and focused on observable contingencies of reinforcement. Radical behaviorism views behavior as shaped entirely by environmental histories through operant conditioning, rejecting mentalistic terms like "purpose" as unnecessary, while purposive behaviorism posits that goals and expectancies guide molar, organismic responses beyond mere response probabilities.^[36]^[38] This emphasis on teleological elements in Tolman highlights a key tension: purposive behaviorism accommodates cognitive-like processes within a behaviorist paradigm, unlike Skinner's purist rejection of them.^[39] Purposive behaviorism shares a holistic orientation with Gestalt psychology, particularly in rejecting atomistic S-R analyses in favor of organized, field-like behavioral units, but it remains anchored in observable behavior rather than the phenomenological introspection central to Gestalt approaches. Influenced by Kurt Lewin's field theory—a bridge between Gestalt and behaviorism—Tolman adopted concepts like valences and tensions to describe goal-directedness, yet he critiqued pure Gestalt for overemphasizing subjective experience without sufficient empirical grounding in animal behavior.^[5] This mutual influence is evident in Tolman's "sign-gestalt" expectancy, which integrates perceptual organization with behavioral outcomes, distinguishing it from Gestalt's focus on innate perceptual constancies.^[40] Relative to Jean Piaget's cognitive developmental theory, purposive behaviorism prefigures ideas like schema formation through its notion of cognitive maps as internalized representations of the environment, but it maintains a behaviorist commitment to observables and empirical prediction over Piaget's emphasis on innate, stage-based mental structures. While Piaget explores how children construct knowledge through assimilation and accommodation, Tolman frames learning as the acquisition of sign-significates—expectancies linking signs to goals—without delving into underlying genetic epistemologies, thus bridging behaviorism and emerging cognitivism.^[36]^[39] This positions Tolman's work as a transitional framework, highlighting behavioral adaptations to purposes rather than purely internal cognitive restructuring.^[1]

Major works

Books by Tolman

Edward Chace Tolman's seminal work, Purposive Behavior in Animals and Men, published in 1932 by the Century Company, spans 463 pages and serves as the foundational text for purposive behaviorism.^[41] In this book, Tolman outlines a framework emphasizing molar behaviorism, which treats behavior as holistic, goal-directed acts rather than fragmented stimulus-response chains.^[42] Key chapters explore sign-learning, where organisms form expectancies linking environmental signs to means-ends relations for achieving purposes, as detailed in sections like "Demands and Means-End-Readinesses."^[41] Tolman also critiques associationism, arguing that traditional S-R models fail to account for purposeful adaptation and cognitive organization in behavior.^[4] In 1942, Tolman published Drives Toward War through D. Appleton-Century Company, a 118-page volume applying purposive behaviorism to social motivation and international conflict amid World War II.^[43] Drawing on biological drives, the book analyzes human propensities for aggression and violence, advocating psychological insights to prevent war through education and social reform.^[44] Tolman extends his theory to group dynamics, emphasizing how expectancies and purposes shape collective behaviors in tense geopolitical contexts.^[45] Tolman's Behavior and Psychological Man: Essays in Motivation and Learning, released in 1951 by the University of California Press, comprises 286 pages of collected essays reflecting a post-war synthesis of his ideas.^[46] These pieces delve into cognition and purpose, such as "A New Formula for Behaviorism" and "Purpose and Cognition," which integrate intervening variables like expectancies to explain motivated learning.^[47] The essays also forge interdisciplinary links, bridging psychology with philosophy and biology to advocate for a purposive, centralist approach over mechanistic models.^[48] Collectively, these books systematize purposive behaviorism by formalizing concepts like goal-directedness and cognitive processes within an empirical framework, profoundly influencing neobehaviorism's shift toward incorporating internal mechanisms in learning theory.^[49] Tolman's works laid groundwork for later developments in cognitive psychology while maintaining a behaviorist commitment to observable data.^[14]

Key articles and papers

One of Edward C. Tolman's most influential articles, "Purpose and Cognition: The Determiners of Animal Learning," published in Psychological Review in 1925, provided an early framework for purposive behaviorism by outlining key terms such as "purpose" and "cognition" as essential intervening variables in understanding animal behavior.^[50] In this work, Tolman argued that behavior is not merely a chain of stimulus-response associations but is directed by cognitive processes and goal-oriented motives, laying the groundwork for his later theories by distinguishing purposive behavior from mechanistic interpretations prevalent in classical behaviorism.^[50] The article emphasized how animals anticipate outcomes and adjust actions accordingly, introducing concepts that would become central to his empirical studies. In 1930, Tolman collaborated with C. H. Honzik on "Introduction and removal of reward, and maze performance in rats," published in University of California Publications in Psychology, which reported data from maze experiments demonstrating latent learning and the goal gradient effect. The study involved rats navigating a multi-unit maze under varying conditions of reward and deprivation, with graphs illustrating performance curves that improved sharply upon the introduction of rewards after initial non-rewarded trials, supporting the idea that learning occurs without immediate reinforcement but manifests when incentives align with expectancies. This empirical evidence challenged strict reinforcement-based models and highlighted how motivational factors like hunger degrees influenced behavioral efficiency.^[51] Tolman's 1948 article, "Cognitive Maps in Rats and Men," in Psychological Review, introduced the concept of cognitive maps as mental representations of spatial environments, drawing from cross-maze experiments where rats demonstrated flexible navigation beyond simple trial-and-error.^[52] Detailing results from studies involving barrier-separated and elevated mazes, the paper showed rats adapting routes efficiently after environmental changes, with analogies to human problem-solving to argue for analogous cognitive processes across species.^[52] This work synthesized purposive behaviorism's emphasis on expectancy and spatial cognition, influencing subsequent research in learning theory. Another notable publication, "There Is More Than One Kind of Learning," appeared in Psychological Review in 1949, where Tolman critiqued dominant theories, including B.F. Skinner's operant conditioning, by reviewing experimental evidence for multiple learning varieties such as place learning, response learning, and latent learning. He contended that no single theory, like reinforcement schedules, could account for all observed behaviors, advocating instead for a pluralistic approach aligned with purposive principles. These articles collectively advanced purposive behaviorism through targeted empirical and theoretical contributions, amassing high citation impacts in psychological literature and bridging behaviorist and cognitive paradigms.
