Idiographic Personality

Personality Processes and Networks

The lab is rethinking the standard way of assessing personality. Instead of exclusively utilizing trait approaches, we are looking at personality from more of an individual, idiographic perspective.

There is a rich history of idiographic assessment in personality dating back to the beginnings of the field. Gordon W. Allport, for example, incorporated idiographic traits into his definition of personality, Raymond B. Cattell offered new ways of thinking about and modeling personality idiographically with the data box and P-technique factor analysis, and Henry Murray's Diagnostic Council offered new ways of systematically approaching idiographic measurement (for a full history, see Beck & Jackson, 2019a).

To do so, we are using cutting-edge methods, which we have reviewed (c.f. Beck & Jackson, 2019b) and implemented (Beck & Jackson, 2019c) in two in press articles. These techniques, which are especially suited to intensive longitudinal data collected through repeated assessments, are showcased in the webapp below.

Moreover, we are using cutting-edge data collection methods, including planned missing data and personalized interventions in Experience Sampling Method studies.

Together, These techniques allow us to understand why personality manifests the way it does as well as the mechanisms of personality continuity and change.

For example, consider the idiographic personality networks below from Beck and Jackson (2019c):
