Does Rehearsal Matter? Left Anterior Temporal Alpha And Theta Band Changes Correlate With The Beneficial Effects Of Rehearsal On Working Memory, Chelsea Reichert Plaska, Kenneth Ng, Timothy M. Ellmore

Publications and Research

Rehearsal during working memory (WM) maintenance is assumed to facilitate retrieval. Less is known about how rehearsal modulates WM delay activity. In the present study, 44 participants completed a Sternberg Task with either intact novel scenes or phase-scrambled scenes, which had similar color and spatial frequency but lacked semantic content. During the rehearsal condition participants generated a descriptive label during encoding and covertly rehearsed during the delay period. During the suppression condition participants did not generate a label during encoding and suppressed (repeated “the”) during the delay period. This was easy in the former (novel scenes) but more difficult in …

The Effects Of Emotional Working Memory Training On Trait Anxiety, Gabrielle C. Veloso, Welison Evenston G. Ty

Psychology Department Faculty Publications

Background: Trait anxiety is a pervasive tendency to attend to and experience fears and worries to a disproportionate degree, across various situations. Decreased vulnerability to trait anxiety has been linked to having higher working memory capacity and better emotion regulation; however, the relationship between these factors has not been well-established.

Objective: This study sought to determine if participants who undergo emotional working memory training will have significantly lower trait anxiety post-training. The study also sought to determine if emotion regulation mediated the relationship between working memory training and trait anxiety.

Method: An experimental group comprising of 49 participants underwent 20 …

Loneliness, Sense Of Control, And Risk Of Dementia In Healthy Older Adults: A Moderated Mediation Analysis, Hwajin Yang, Germaine Tng, Wee Qin Ng, Sujin Yang

Research Collection School of Social Sciences

Objectives: Despite the rising prevalence of dementia, little research has been conducted to identify modifiable psychological factors that alleviate the risk of dementia in older adults and the underlying mechanisms. Given that loneliness is, in part, concomitant with a weakened sense of control, we examined whether sense of control would mediate the relation between loneliness and dementia risk. Further, considering that working -memory capacity is a critical cognitive resource that serves as a buffer against age-related cognitive decline, we examined a second-order moderated mediational model whereby working-memory capacity moderates the relation between control beliefs and dementia risk in older adults. …
