Personality Project

Scientific objectives:

1. To gain an increased understanding of the ways in which personality and situational determinants of motivation combine to influence motivational states, and how these motivational states in turn affect cognitive processes to determine cognitive performance.
2. To understand the structure of human personality at multiple levels of analysis, including within individual, between individual, and between self selected aggregates of individuals.

Methods:

1. Experimental studies of the effect of various motivational manipulations on cognitive performance.
2. Web based data collection using Synthetic Aperture Personality Assessment (SAPA) techniques to examine the structure of large number of temperament, ability, and interest items from people around the world.
3. Using other telemetric techniques to examine the structure of affect, cognition and desire as they relate to behavior within individuals across time.
4. Development of open source programs and materials to facilitate these goals.

Recent PMC Publications

The Personality, Motivation and Cognition lab is more than just SAPA, for we are interested in the broad questions of what is personality, how does it vary within and between individuals, how does it relate to emotional states. We are also very interested in the Open Science movement. For more information about the PMC lab see the publication list for William Revelle , David M. Condon , Joshua Wilt, Jason French, Ashley Brown and Lorien Elleman.)

The Personality Project

A continously growing set of pages meant to guide those interested in personality theory and research to the current personality research literature. Although some of the readings are available on-line, all should be available from most university libraries. Information about scholarly societies and graduate training programs in personality is provided for those interested in pursuing further study in personality theory. Course syllabi from personality theory and research courses are being added gradually. Links to active researchers and personality laboratories are added when found (and as time allows).

Computer Programs developed at the lab

Obviously the most visible program developed at the PMC lab is the psych package which has been released to CRAN since 1997. psych is a general purpose toolbox for personality, psychometric theory and experimental psychology. Functions are primarily for multivariate analysis and scale construction using factor analysis, principal component analysis, cluster analysis and reliability analysis, although others provide basic descriptive statistics. Item Response Theory is done using factor analysis of tetrachoric and polychoric correlations. Functions for analyzing data at multiple levels include within and between group statistics, including correlations and factor analysis. Functions for simulating and testing particular item and test structures are included. Several functions serve as a useful front end for structural equation modeling. Graphical displays of path diagrams, factor analysis and structural equation models are created using basic graphics. Some of the functions are written to support a book on psychometric theory as well as publications in personality research. For more information, see the personality-project.org/r web page
