Effect of visual cues with the WAIS--R Digit Span subtest

Area of Science:

• Cognitive Psychology
• Neuropsychology
• Human Development

Background:

• The Digit Span subtest of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) is a common measure of working memory capacity.
• Previous research has explored factors influencing digit span performance, including age and potential confounding variables.

Purpose of the Study:

• To investigate whether sex differences exist in digit span recall performance.
• To determine if visual cues from an examiner affect digit span recall in young adults.

Main Methods:

• Administered the WAIS-R Digit Span subtest to 43 women and 31 men (ages 18-19).
• Tested participants under two conditions: standard (examiner facing) and obscured (examiner behind).
• Utilized analysis of variance (ANOVA) to compare recall scores.

Main Results:

• No statistically significant differences in total digits recalled were found between male and female participants.
• No significant differences in digit span performance were observed between the standard and obscured examiner presentation methods.
• The results suggest that visual cues from the examiner do not influence digit span recall in this age group.

Conclusions:

• Sex is not a significant factor in WAIS-R Digit Span performance for young adults.
• Eliminating visual cues does not alter digit span recall, indicating robustness against examiner-related visual confounds.
• This study supports the reliability of the Digit Span subtest across different presentation conditions and sexes.
