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
Kristy Nielson
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
Kristy 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
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
Kristy Nielson
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 …
Hot And Bothered: The Role Of Arousal And Rejection Sensitivity In Dual Process Sexual Decision Making For Gay And Bisexual Men, H Jonathon Rendina
Hot And Bothered: The Role Of Arousal And Rejection Sensitivity In Dual Process Sexual Decision Making For Gay And Bisexual Men, H Jonathon Rendina
Dissertations, Theses, and Capstone Projects
Dual process theories of decision making acknowledge the functioning of two distinct yet simultaneous processes termed System 1 and System 2. While System 1 relies more heavily on automatic and affective processing, System 2 relies more heavily on effortful and cognitive processing. Over the past several decades, many lines of research have shown the importance of System 1 in decision making and several prominent social psychological theories of interpersonal behavior, such as rejection sensitivity, rely on this dual distinction between affective and cognitive processing. Despite the prominence of dual process theories in many areas of psychology, the role of System …

To expose cortical involvement in age-related changes in motor performance, we compared steadiness (force fluctuations) and fatigability of submaximal isometric contractions with the ankle dorsiflexor muscles in older and young adults and with varying levels of cognitive demand imposed. Sixteen young (20.4 ± 2.1 year: 8 men, 9 women) and 17 older adults (68.8 ± 4.4 years: 9 men, 8 women) attended three sessions and performed a 40 s isometric contraction at 5% maximal voluntary contraction (MVC) force followed by an isometric contraction at 30% MVC until task failure. The cognitive demand required during the submaximal contractions in each session …
The Effects Of Musical Mood And Musical Arousal On Visual Attention, Angela B. Marti Marca, Tram Nguyen, Jessica Grahn
The Effects Of Musical Mood And Musical Arousal On Visual Attention, Angela B. Marti Marca, Tram Nguyen, Jessica Grahn
Undergraduate Honors Theses
The presence of music is a visceral part of the human experience and its influence on cognitive function is a growing area of research in psychology. In particular, perceptual properties of music (mood and arousal) have been shown to significantly affect performance. There has been minimal research in the field on the interaction of mood and arousal and their influence on attention, thus the purpose of this study. Fifty undergraduate students currently enrolled at the University of Western Ontario were recruited for this study. Given that music is a highly subjective experience, participants rated an assortment of music clips on …

The presence of music is a visceral part of the human experience and its influence on cognitive function has become a growing area of research in psychology. In particular, perceptual properties of music (mood and arousal) have been shown to significantly affect performance. There has been minimal research in the field on the interaction of these perceptual properties and their influence on attentional processes. This research study focused on the effects of musical mood and musical arousal on visual attention. Given that music is a highly subjective experience, participants were asked to rate different music clips on independent dimensions of …
Muscle Tension Induced After Learning Enhances Long-Term Narrative And Visual Memory In Healthy Older Adults, Kristy A. Nielson, Laura L. Wulff, Timothy J. Arentsen
Muscle Tension Induced After Learning Enhances Long-Term Narrative And Visual Memory In Healthy Older Adults, Kristy A. Nielson, Laura L. Wulff, Timothy J. Arentsen
Psychology Faculty Research and Publications
Arousing events are better remembered than mundane events. Indeed, manipulation of arousal, such as by muscle tension, can influence memory even when it occurs shortly after learning. Indeed, our founding study showed this approach can raise delayed memory performance in older adults to a level comparable to that of unaided young adults. Yet, systematic studies, especially those investigating different modalities or types of memory, have not been done. This study investigated the effects of a brief bout of isometric exercise via handgrip on narrative and visuospatial episodic memory in healthy elders. Forty-seven participants completed the Logical Memory subtest of the …
