However, they can be measured using projective devices such as the Thematic Apperception Test (TAT).
- Independent

- Independent self
- The tendency to define the self in terms of stable traits that guide behavior.
- Independent variable
- The variable the researcher manipulates and controls in an experiment.

- Interdependent self
- The tendency to define the self in terms of social contexts that guide behavior.

- Latent inhibition
- The ability to filter out extraneous stimuli, concentrating only on the information that is deemed relevant. Reduced latent inhibition is associated with higher creativity.
- Letter of recommendation effect
- The general tendency for informants in personality studies to rate others in an unrealistically positive manner. This tendency is due a pervasive bias in personality assessment: In the large majority of published studies, informants are individuals who like the person they are rating (e.g., they often are friends or family members) and, therefore, are motivated to depict them in a socially desirable way. The term reflects a similar tendency for academic letters of recommendation to be overly positive and to present the referent in an unrealistically desirable manner.
- Lexical hypothesis
- The lexical hypothesis is the idea that the most important differences between people will be encoded in the language that we use to describe people. Therefore, if we want to know which personality traits are most important, we can look to the language that people use to describe themselves and others.
- Lexicon
- Words and expressions.
- Life course theories

Informants also can show enhancement biases.

- The tendency of parents to use their perceptions of all of their children as a frame of reference for rating the characteristics of each of them. For example, suppose that a mother has three children; two of these children are very sociable and outgoing, whereas the third is relatively average in sociability. Because of operation of this effect, the mother will rate this third child as less sociable and outgoing than he/she actually is. More generally, this effect causes parents to exaggerate the true extent of differences between their children. This effect represents a specific manifestation of the more general reference group effect when applied to ratings made by parents.
