participant

n. a person who takes part in an investigation, study, or experiment, such as by performing tasks set by the experimenter or by answering questions set by a researcher. In an experimental design, the person may be further identified as an experimental participant (see experimental group) or a control participant (see control group). Participants may also be referred to as subjects, particularly by those who wish to avoid the implication that experimentees are involved in the construction, design, conduct, and analysis of the experiment. See also respondent.

hierarchical model of personality

a model of either within-person dynamics or individual differences in personality in which some psychological constructs are viewed as high-level variables that organize or govern the functioning of other lower level variables. For example, a hierarchical model of personality traits might view the construct sociability as being at a lower level in a hierarchy than the construct extraversion: Sociability would be seen as a form or example of the higher level trait of extraversion.
