Picture Story Exercise (PSE) — Implicit Motive Assessment
The Picture Story Exercise (PSE) is a projective assessment that reveals unconscious motivational drives — Achievement (nAch), Affiliation (nAff), and Power (nPow) — through narrative coding. Predicts long-term behavioral outcomes that self-report measures miss.
Administration
Participants view 5 evocative images and write creative stories about what is happening, what led up to the situation, what the characters are thinking and feeling, and what will happen next. Minimum 30 words per story. Completion time approximately 15 minutes.
Psychometric Properties
Inter-rater reliability: .85–.95 for category agreement between trained coders (Winter, 1994). Normative database: N = 4,774 cross-cultural research participants with percentile norms. Low implicit-explicit correlation (r ≈ .00–.15) confirms measurement of a different motivational system.
Clinical Applications
Implicit-explicit motive conflict identification, leadership and power dynamics assessment, career counseling, psychotherapy process, health and stress prediction, couples therapy.
