Personality, Motivation, and Cognition Laboratory

at the Department of Psychology ,
Northwestern University

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 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.

Other programs that have been developed as stand alone application programs for Macintosh computers. Source code in Lightspeed Pascal is also available. Publications that describe the algorithms or applications of these programs are listed.

ALPHA-VSS-ICLUST
ALPHA-VSS-ICLUST is a general purpose program for scale construction, hierarchical cluster analysis, and applying the Very Simple criterion. Some simple data manipulation options are also available. Hierarchical clustering is done using the alpha and beta criteria of cluster goodness. (Beta is an estimate of the worst split half reliability of a cluster and thus is an estimate of the general factor saturation of a test).
PMC-RT
PMC-RT is a set of simple and choice reaction time procedures allowing for the measurement of rt as well as the assessment of changes in rt over time.

PMC-ANALOGIES
True false or multiple choice geometric analogies that vary in the number of elements and transformations applied per element. Accuracy and rt measures are taken. Elements may vary from 1-4 and transformations from 0-4.

Working-Memory .
Working memory for 2-10 digits following the true false verification of arithmetic problems. Speed and accuracy of the digit verification are reported, as are strict and lax memory scores.

PMC_units
A set of Pascal units that have been developed to allow for standardized programing of psychology experiments and data analysis.
