Area of Science:

Cognitive Psychology
Educational Psychology
Neuroscience

Background:

Assessing cognitive functions like memory requires reliable measurement tools.
Understanding the temporal stability of memory tests is crucial for longitudinal studies and clinical assessments.
The Learning Efficiency Test-II is a tool designed to evaluate memory processing.

Purpose of the Study:

To evaluate the temporal stability of the Learning Efficiency Test-II.
To determine the reliability of factor scores (Visual Modality, Auditory Modality, Global Memory) and subtest scores over a short retest interval.
To assess the stability of memory processes in undergraduate students.

Main Methods:

The study involved 101 undergraduate students.
The Learning Efficiency Test-II was administered twice with a mean retest interval of 19 days.
Temporal stability was assessed using correlation coefficients and repeated measures ANOVA.

Main Results:

High temporal stability was found for factor scores: Visual Modality (.79), Auditory Modality (.75), and Global Memory (.80).
No significant mean differences were observed between test and retest scores for these factors.
Retest correlations for the 12 subtests ranged from .44 to .70, indicating moderate to good reliability for some subtests.

Conclusions:

The Learning Efficiency Test-II shows good temporal stability for assessing memory processing in undergraduate students over a 19-day interval.
Memory processes appear stable in intact learners over this period.
Further research is recommended with diverse age groups to confirm score stability.
