This study explored how aging affects older adults' intrapsychic processes using the Hand Test (HT). Findings reveal significant age-related changes in HT performance, contrasting with theories of adult personality stability.

Area of Science:

  • Psychology
  • Gerontology
  • Personality Assessment

Background:

  • Cultural differences and aging impact intrapsychic processes.
  • Previous research focused on socioadaptational levels, not projective methods.
  • Projective assessments offer unique insights into personality changes.

Purpose of the Study:

  • To investigate cultural and time-of-measurement effects on older adults' intrapsychic processes.
  • To compare Hand Test (HT) performance across different cohorts of older adults.
  • To examine age-related variance in projective test performance.

Main Methods:

  • Time-lagged analysis of Hand Test (HT) scores.
  • Comparison of two distinct samples of older adults (1976 and 1986).
  • Utilized projective assessment methods to evaluate personality functioning.

Main Results:

  • Significant age-related variance observed in both content and derived Hand Test (HT) variables.
  • Within-sample variability in most HT scores supported age-related changes.
  • Findings contrast with studies showing personality stability in adulthood using nomothetic measures.

Conclusions:

  • Intrapsychic processes in older adults show age-related variability, as indicated by Hand Test (HT) performance.
  • Projective methods reveal developmental shifts in personality not always captured by standardized tests.
  • Cultural and temporal factors may influence personality expression across the lifespan in older adults.
