- 9Heuristica strategy, guiding principle, or rule of thumb, used in solving problems or making decisions.
- 10Hypnosisa systematic procedure that typically produces a heightened state of suggestibility
- 11Behaviour modifcationA systematic approach to changing behaviour through the application of the principles of conditioning
- 12Conditioned responsea learned reaction to a conditioned stimulus that occurs because of previous conditioning
- 13Classical conditioningA type of learning in which a neutral stimulus acquires the ability to evoke a response that was originally evoked by another stimulus.
- 14Dependent variablein an experiment, the variable that is thought to be affected by the manipulation of the independent variable.
- 15Decision makingthe process of evaluating alternative and making choices among them.
- 16Field dependence-independenceindividuals tendency to rely primarily on external versus internal frames of reference when orienting themselves in space.

- 18Absolute thresholdthe minimum amount of stimulation that an organism can detect for a specific type of sensory input.
- 19Independent variablein an experiment, condition, or event that an experiment varies in order to see its impact on another variable.
- 20insomniachronic problems in getting adequate sleep
- 21Law of effectthe principle that if a response in the presence of a stimulus leads to satisfying effects, the association between the stimulus and the response is strengthened.

- 31Sensationthe stimulation of sense organs
- 32Unconditioned responsean unlearned reaction to an unconditioned stimulus that occurs without previous conditioning
- 33Signal-detection theorya psychophysiological theory proposing that they detection of stimuli involves decision processes as well as sensory processes, which are influenced by a variety of factors besides the physical intensity of a stimulus
