Memory test consistency on the Wide Range Assessment of Memory and Learning (WRAML) increases with age, but significant performance variability persists across subtests and age groups. This highlights the need for careful interpretation of WRAML results in clinical practice.

Area of Science:

  • Neuropsychology
  • Developmental Psychology
  • Educational Psychology

Background:

  • The Wide Range Assessment of Memory and Learning (WRAML) is a key tool for assessing memory functioning.
  • Understanding test consistency and performance variability is crucial for accurate diagnosis and intervention.
  • Previous research has not fully explored age-related changes in WRAML subtest consistency and base-rate variability.

Purpose of the Study:

  • To examine developmental changes in memory test consistency using the WRAML.
  • To investigate base-rate variability in WRAML performance across different age cohorts.
  • To provide implications for the clinical interpretation of WRAML scores.

Main Methods:

  • Two studies analyzed data from the WRAML standardization sample across three age groups (5, 11, and 16-17 year olds).

  • Study 1 assessed inter-subtest correlations to measure test consistency.
  • Study 2 calculated base-rate variability for discrepancies between subtests, index scores, and performance below normative means.

    • Main Results:

    • Inter-task consistency on the WRAML showed an age-related increase, with higher correlations in older age groups.
    • Despite this increase, correlation coefficients remained in the low to moderate range, indicating substantial performance variability across memory subtests.
    • Performance discrepancies were generally higher in the youngest age group, with considerable variability observed across all cohorts.

    Conclusions:

    • While WRAML consistency improves with age, significant performance variability exists across all developmental stages.
    • Clinicians should exercise caution when interpreting WRAML scores due to potential inconsistencies.
    • Base-rate information on performance variability is essential for accurate clinical assessment and diagnosis.
