 In his attempts to explain behavior, Tolman introduced a set of environmental and individual difference variables. Individual difference variables are heredity, age, previous training and special endocrine, drug or vitamin conditions (also called //HATE// variables).(([[http://​books.google.com/​books?​id=QTwOAAAAQAAJ|Hill,​ Winfred Farrington. Learning: a survey of psychological interpretations. Taylor & Francis, 1980.]])) This variables offer a rarely seen broad view over the theory of learning. In his attempts to explain behavior, Tolman introduced a set of environmental and individual difference variables.

-Based on conducted rats experiments,​ Tolman introduced the term of **//latent learning//​**.(([[http://​fac.hsu.edu/​ahmada/​3%20Courses/​2%20Learning/​Learning%20Notes/​9%20Tolman.pdf|Ahmad, ​A. Principles of Learning. Chapter 12: Edward Tolman.]] Retrieved August 24, 2011.)) This type of learning does not require motivation or reinforcement. In one experiment, Tolman put two groups of rats in a maze with a reward hidden in it. Later, he changed the place where rats were put in the maze, but so that the second group of rats had to perform the same set of turns in order to reach food. The first group was more successful, showing that learning was not just a raw set of movements. Tolman offered an explanation that rats created a **"​cognitive map"** of the maze and used it to solve the problem. He confirmed this finding in some later experiments as well, but never tried to investigate this cognitive map.+Based on conducted rats experiments,​ Tolman introduced the term of **//latent learning//​**.(([[http://​fac.hsu.edu/​ahmada/​3%20Courses/​2%20Learning/​Learning%20Notes/​9%20Tolman.pdf|Ahmad, ​Aneeq.

 What Tolman also concluded based on other experiments with rats is that **rewards** or **punishments** can only be used as **motivators for performance** of a learned behavior, but not as the initiators of learning. Tolman saw animals not just as simple mechanisms, but as intelligent organisms testing hypotheses based on their prior experience and capable of cognitive processes. What Tolman also concluded based on other experiments with rats is that **rewards** or **punishments** can only be used as **motivators for performance** of a learned behavior, but not as the initiators of learning.

 According to Tolman, learning occurs as learners **following signs** (stimuli) **to a goal**. Learning was about finding a way and **meanings instead of reproducing behaviors**. Organisms learn behavior route and relations rather than behavior patterns. There is no need for reinforcement when speaking about learning since the behavior is driven by a meaning. According to Tolman, learning occurs as learners **following signs** (stimuli) **to a goal**.

-In the end Tolman, influenced by Guthrie, Freud and reinforcement theorists, concluded there are **six forms of learning**, each with its own characteristics:​(([[http://​fac.hsu.edu/​ahmada/​3%20Courses/​2%20Learning/​Learning%20Notes/​9%20Tolman.pdf|Ahmad, ​A.

In example, vegans tend to satisfy their hunger with non-animal products (positive cathexis), and not meat (negative cathexis).   * **Cathexis**((Term taken from Freud'​s psychoanalytic theory of motivation)) - learned tendency to **associate certain objects with certain drives**.
