"Behavioral sink" is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation.The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. [1]
The sugar experiment lasted until 1949 when the trials were revised again, now to test a more "normal" carbohydrate-rich diet. By then, the teeth of about fifty of the 660 subjects in the experiment had been completely damaged. [8] Nonetheless, the researchers felt that, scientifically speaking, the experiment was a success.

The bunker experiment had far-reaching implications in the medical field, for example in understanding problems related to shift work and jet lag. [18] In addition, it allowed for a better understanding of affective disorders in relation to the synchronization of the internal circadian clock and the light-dark and sleep-wake cycles.
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
The experimenter gave the perceivers pictures which portrayed either physically attractive or physically unattractive women in order to activate the perceiver's stereotypes that they may possess concerning attractive and unattractive people. The perceiver-target dyads engaged in a 10-minute, unstructured conversation, which was initiated by the ...
Experiment 2 focused on how the substantive content of cognitions can affect subsequent delay behavior. The conditions in Experiment 2 were the same as in Experiment 1, with the exception that after the three comprehension questions were asked of the children the experimenter suggested ideas to think about while they were waiting.
The Bobo doll experiment (or experiments) is the collective name for a series of experiments performed by psychologist Albert Bandura to test his social learning theory. Between 1961 and 1963, he studied children's behaviour after watching an adult model act aggressively towards a Bobo doll . [ 1 ]
Shaping sometimes fails. An oft-cited example is an attempt by Marian and Keller Breland (students of B.F. Skinner) to shape a pig and a raccoon to deposit a coin in a piggy bank, using food as the reinforcer. Instead of learning to deposit the coin, the pig began to root it into the ground, and the raccoon "washed" and rubbed the coins together.
