Is Younger Really Better? Age Differences In Emotion Perception, Kaitlyn Snyder

Mahurin Honors College Capstone Experience/Thesis Projects

Previous research suggests that younger adults outperform older adults on emotion-matching tasks because emotion recognition ability declines with age. These studies involved tasks in which participants identified a target emotion by selecting from multiple verbal labels. The use of multiple verbal labels placed great cognitive demand on participants, influencing the results that were found in such studies. In the present study, a computer emotion-matching task was used to determine differences between younger and older adults when presented with a target stimulus expressing one of five emotions (anger, fear, disgust, happiness, and sadness) and asked to match the target emotion to …

A Critical Evaluation Of Selective Attention Measures, Hannah K. Wilson

Mahurin Honors College Capstone Experience/Thesis Projects

Selective attention is comprised of two simultaneous processes—the inhibition of distractors and the focus of attention on target stimuli; yet, many existing selective attention measures only measure one aspect of selective attention. This leads to a high possibility of Type I errors as high interference control or high working memory capacity may be mistaken for high selective attention. This paper proposes several criteria for high construct validity and external validity in selective attention measures.

Concerning construct validity, the test must allow participants to exercise selective attention, adequately measure the level of attention to the distractor stimuli, and adequately measure level …
