Ramachandran, Vilayunar S.

Neuro-Plasticity and neurological development and growth. Works with amputees and with people with amazing brains.

Rescorla, Robert

Proposed that there is a conscious connections between the CS and the UCS in classical conditioning experiments. (A smoker is aware that a nausea-producing drug will affect his behavior) Stated that the predictive value of a conditioned stimulus is critical, contingencies are important. The Rescorla-Wagner model is a formal model of the circumstances under which Pavlovian conditioning occurs. It attempts to describe the changes in associative strength (V) between a signal (conditioned stimulus, CS) and the subsequent stimulus (unconditioned stimulus, US) as a result of a conditioning trial. The model emerged in the early 1970s (Rescorla and Wagner 1972) as an attempt to deal with empirical results suggesting that the idea of simple co-occurrence of two events, important in historical philosophical, psychological, and biological thinking, was inadequate.

Schachter, Stanley

Emotion occurs when we apply a particular label to general physical arousal- we have to interpret our feelings. Proposed the two factor theory of emotion; physiological arousal and a cognitive label. A person's experience of an emotion stems from the mental awareness of the body's physical arousal.

Schachter-Singer Experiment

showed that emotions have both a physical and a cognitive component.

Schafer, Roy- Psychoanalyst who emphasizes a psychoanalytic concept of narrative. For Schafer, an important purpose of the analytic process is that the subject regains agency of her own story and of her own life. Psychoanalyst and subject each have a role in telling and retelling the subject’s life story: the analyst helps the subject by elevating subjectivity as awareness of multiple interpretations.

Seligman, Martin

“Learned Helplessness Experiment” with dogs. Showed the external locus effect in animals (generalized to depression with humans). Prepared for fear theory- we are prepared by evolution to readily develop fears to certain biologically relevant stimuli, such as snakes and spiders. Created the concept of learned helplessness. Proposed the creation of a Positive Psychology.

Selye, Hans

General Adaptation Syndrome (stress responses). Studied stress- the body responds in the same way to any stress (infection, failure, embarrassment, a new job, trouble at school etc.) General Adaptation Syndrome- a series of bodily reactions to prolonged stress (alarm, resistance, exhaustion).

Sternberg, Robert

Sternberg (2003) categorizes intelligence into three parts, which are central in his theory, the triarchic theory of intelligence: Analytical intelligence, the ability to complete academic, problem-solving tasks, such as those used in traditional intelligence tests. Creative or synthetic intelligence, the ability to successfully deal with new and unusual situations by drawing on existing knowledge and skills.

Szasz, Thomas Stephen

Social critic of the moral and scientific foundations of psychiatry, and of the social control aims of medicine in modern society, as well as of scientism.

Terman, Lewis

Revised Binet’s intelligence test to help create the Stanford-Binet Intelligence Scales for use in North America, appropriate for people ages 2-90.

Thorndike, Edward L.

Learning theorist: Law of Effect- the probability of a response is altered by the effect it has, acts that are reinforced tend to be repeated
