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

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 …
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 …
Modulation Of Long-Term Memory By Arousal In Alexithymia: The Role Of Interpretation, Kristy A. Nielson, Mitchell A. Meltzer
Modulation Of Long-Term Memory By Arousal In Alexithymia: The Role Of Interpretation, Kristy A. Nielson, Mitchell A. Meltzer
Psychology Faculty Research and Publications
Moderate physiological or emotional arousal induced after learning modulates memory consolidation, helping to distinguish important memories from trivial ones. Yet, the contribution of subjective awareness or interpretation of arousal to this effect is uncertain. Alexithymia, which is an inability to describe or identify one’s emotional and arousal states even though physiological responses to arousal are intact, provides a tool to evaluate the role of arousal interpretation. Participants scoring high and low on alexithymia (N = 30 each) learned a list of 30 words, followed by immediate recall. Participants then saw either an arousing (oral surgery) or neutral video (tooth …
Positive And Negative Sources Of Emotional Arousal Enhance Long-Term Word-List Retention When Induced As Long As 30 Min After Learning, Kristy A. Nielson, Mark R. Powless
Positive And Negative Sources Of Emotional Arousal Enhance Long-Term Word-List Retention When Induced As Long As 30 Min After Learning, Kristy A. Nielson, Mark R. Powless
Psychology Faculty Research and Publications
The consolidation of newly formed memories occurs slowly, allowing memories to be altered by experience for some time after their formation. Various treatments, including arousal, can modulate memory consolidation when given soon after learning, but the degree of time-dependency of these treatments in humans has not been studied. Thus, 212 participants learned a word list, which was followed by either a positively or negatively valenced arousing video clip (i.e., comedy or surgery, respectively) after delays of 0, 10, 30 or 45 min. Arousal of either valence induced up to 30 min after learning, but not after 45 min, significantly enhanced …
Memory Enhancement By A Semantically Unrelated Emotional Arousal Source Induced After Learning, Kristy A. Nielson, Douglas Yee, Kirk I. Erickson
Memory Enhancement By A Semantically Unrelated Emotional Arousal Source Induced After Learning, Kristy A. Nielson, Douglas Yee, Kirk I. Erickson

It has been well established that moderate physiological or emotional arousal modulates memory. However, there is some controversy about whether the source of arousal must be semantically related to the information to be remembered. To test this idea, 35 healthy young adult participants learned a list of common nouns and afterward viewed a semantically unrelated, neutral or emotionally arousing videotape. The tape was shown after learning to prevent arousal effects on encoding or attention, instead influencing memory consolidation. Heart rate increase was significantly greater in the arousal group, and negative affect was significantly less reported in the non-arousal group after …
The Effects Of Non-Contingent Extrinsic And Intrinsic Rewards On Memory Consolidation, Kristy A. Nielson, Ted Bryant
The Effects Of Non-Contingent Extrinsic And Intrinsic Rewards On Memory Consolidation, Kristy A. Nielson, Ted Bryant
Psychology Faculty Research and Publications
Emotional and arousing treatments given shortly after learning enhance delayed memory retrieval in animal and human studies. Positive affect and reward induced prior to a variety of cognitive tasks enhance performance, but their ability to affect memory consolidation has not been investigated before. Therefore, we investigated the effects of a small, non-contingent, intrinsic or extrinsic reward on delayed memory retrieval. Participants (n = 108) studied and recalled a list of 30 affectively neutral, imageable nouns. Experimental groups were then given either an intrinsic reward (e.g., praise) or an extrinsic reward (e.g., $1). After a one-week delay, participants’ retrieval performance …
