Fixation: failure to move forward from one stage of psychosexual development to
Heritability Ratio: an estimate of the proportion of the trait to be passed down to other
Hierarchy of Needs: systematic arrangement of needs, according to priority, in which
basic needs must be met before advancing to other needs. (Pyramid)
Hindsight Basis: common tendency to mold one’s interpretation of the past to fit how

stimuli in ways that may reveal the subjects needs, feelings or traits. (ie, inkblot test)

unconscious mental forces.
Psychosexual Stages: developmental periods with a characteristic sexual focus that leave
their mark on adult personality.
Punishment: the weakening of a response because it is followed by the arrival of a
Rationalization: creating false but plausible excuses to justify unacceptable behaviour.
Reaction Formation: behaving in a way that is exactly opposite of one’s true feelings.
Regression: reversion to immature patterns of behaviour.
Self-concept: collection of beliefs about one’s basic nature, unique qualities and typical
Self-efficacy: belief about one’s ability to perform behaviours that should lead to
Self-report Inventories: personality scales that ask individuals to answer a series of
questions about their characteristic behaviour.
Sensation Seeking: generalized preference for high or low levels of sensory stimulation.
Sublimation: defense mechanism that occurs when unconscious, unacceptable, impulses
are channeled into socially acceptable, perhaps even admirable, behaviours.
Superego: the moral component of personality that incorporates social standards about
what represents right and wrong.
Twin Studies: research method in which researchers assess hereditary influence by
comparing the resemblance of identical twins and fraternal twins on a trait.
Unconditioned Response: an unlearned reaction to an unconditioned stimulus that
occurs without previous conditioning.
Unconditioned Stimulus: stimulus that evokes an unconditioned response with out
Unconscious: thoughts, memories, desires that are well below the surface of conscious
awareness but that nonetheless exert great influence on our behaviour.
