Memory Modulation In The Classroom: Selective Enhancement Of College Examination Performance By Arousal Induced After Lecture, Kristy A. Nielson, Timothy J. Arentsen
Memory Modulation In The Classroom: Selective Enhancement Of College Examination Performance By Arousal Induced After Lecture, Kristy A. Nielson, Timothy J. Arentsen

Laboratory studies examining moderate physiological or emotional arousal induced after learning indicate that it enhances memory consolidation. Yet, no studies have yet examined this effect in an applied context. As such, arousal was induced after a college lecture and its selective effects were examined on later exam performance. Participants were divided into two groups who either watched a neutral video clip (n = 66) or an arousing video clip (n = 70) after lecture in a psychology course. The final examination occurred two weeks after the experimental manipulation. Only performance on the group of final exam items that covered material …
Memory For Emotionally Provocative Words In Alexithymia: A Role For Stimulus Relevance, Mitchell Meltzer, Kristy A. Nielson
Memory For Emotionally Provocative Words In Alexithymia: A Role For Stimulus Relevance, Mitchell Meltzer, Kristy A. Nielson

Alexithymia is associated with emotion processing deficits, particularly for negative emotional information. However, also common are a high prevalence of somatic symptoms and the perception of somatic sensations as distressing. Although little research has yet been conducted on memory in alexithymia, we hypothesized a paradoxical effect of alexithymia on memory. Specifically, recall of negative emotional words was expected to be reduced in alexithymia, while memory for illness words was expected to be enhanced in alexithymia. Eighty-five high or low alexithymia participants viewed and rated arousing illness-related ("pain"), emotionally positive ("thrill"), negative ("hatred"), and neutral words ("horse"). Recall was assessed 45 …
Reduction Of The Misinformation Effect By Arousal Induced After Learning, Shaun English, Kristy Nielson
Reduction Of The Misinformation Effect By Arousal Induced After Learning, Shaun English, Kristy Nielson

Misinformation introduced after events have already occurred causes errors in later retrieval. Based on literature showing that arousal induced after learning enhances delayed retrieval, we investigated whether post-learning arousal can reduce the misinformation effect. 251 participants viewed four short film clips, each followed by a retention test, which for some participants included misinformation. Afterward, participants viewed another film clip that was either arousing or neutral. One week later, the arousal group recognized significantly more veridical details and endorsed significantly fewer misinformation items than the neutral group. The findings suggest that arousal induced after learning reduced source confusion, allowing participants to …
Enhanced Post-Learning Memory Consolidation Is Influenced By Arousal Predisposition And Emotion Regulation But Not By Stimulus Valence Or Arousal, Kristy Nielson, William Lorber
Enhanced Post-Learning Memory Consolidation Is Influenced By Arousal Predisposition And Emotion Regulation But Not By Stimulus Valence Or Arousal, Kristy Nielson, William Lorber

Emotionally arousing stimuli are more memorable than neutral ones and arousal induced after learning enhances later retrieval. However, there is as yet little study of how stimulus qualities might interact with induced arousal and how individual differences might influence the modulation of memory. Thus, the present study examined the effect of arousal induced after learning on memory for words that varied in both arousal and valence quality, as well as the influence of three individual differences factors that are known to influence arousal response: emotional suppression, emotional reappraisal, and arousal predisposition. Seventy-six adults (57 female) viewed and rated 60 words …
