An influential idea about memory and medial temporal lobe function suggests that hippocampal activity predicts subsequent recognition success only when decisions are based on recollection, whereas perirhinal activity predicts subsequent recognition success when decisions are based on familiarity. An alternative idea is that hippocampal and perirhinal activity are both sensitive to the level of overall memory strength. Using functional magnetic resonance imaging, we have tested the relationship between brain activity during learning and subsequent memory strength. Activity in a number of cortical regions (including regions within what has been termed the default network) was negatively correlated with subsequent memory strength, …
Just Say “Nootropic”: The Effects Of Nicotine On Memory And Learning, Elyse N. Goveia
Just Say “Nootropic”: The Effects Of Nicotine On Memory And Learning, Elyse N. Goveia
Psychology Honors Papers
This study investigated the effects of nicotine on memory and learning in adolescent and adult male Fischer-344 rats. Rats were given 0.2 mg/kg/day of either nicotine or saline chronically for 2 weeks and were tested in the Morris water maze as adolescents (Phase 1) and then again 4 months later as adults (Phase 2). There were 4 main groups: nicotine/nicotine, nicotine/saline, saline/nicotine, and saline/saline. In Phase 2 rats were tested for c-Fos and BrdU expression in the dentate gyrus of the hippocampus. Behavioral data indicated that as adults, rats given nicotine were significantly improved at the water maze task compared …
Biases In Interpretation And Memory In Generalized Social Phobia, Paula T. Hertel, F. Brozovich, Jutta Joormann, Ian Henry Gotlib
Biases In Interpretation And Memory In Generalized Social Phobia, Paula T. Hertel, F. Brozovich, Jutta Joormann, Ian Henry Gotlib
Psychology Faculty Research
Two experiments examined the link between interpretation and memory in individuals diagnosed with Generalized Social Phobia (GSP). In Experiment 1, GSP and control participants generated continuations for nonsocial and ambiguous social scenarios. GSP participants produced more socially anxious and negative continuations for the social scenarios than did the controls. On the subsequent test of recalling the social scenarios, intrusion errors that shared meaning with the original continuations were made more frequently by the GSP group, producing false recall with emotionally negative features. To examine whether nonanxious individuals would also produce such errors if given emotional interpretations, in Experiment 2 the …
Depression-Related Differences In Learning And Forgetting Responses To Unrelated Cues, Paula T. Hertel, A. Mahan
Depression-Related Differences In Learning And Forgetting Responses To Unrelated Cues, Paula T. Hertel, A. Mahan
Psychology Faculty Research
Using the think/no-think paradigm, we examined the effect of a meaningful connection between emotionally neutral cues and targets on initial learning and later recall by students in dysphoric or nondysphoric mood states. Compared to meaningfully connected cue-target pairs, unrelated pairs were less easily learned and more easily forgotten, even when initial learning was controlled. Depressive deficits were obtained in initial learning (only marginally) and final recall. When examined separately within each cuing condition, the recall deficit associated with depressed mood was restricted to the unrelated condition, but when initial learning differences were controlled this deficit was only marginally significant. Results …
Dredging Up The Past: Lifelogging, Memory And Surveillance, Anita L. Allen
Dredging Up The Past: Lifelogging, Memory And Surveillance, Anita L. Allen
All Faculty Scholarship
The term “lifelog” refers to a comprehensive archive of an individual's quotidian existence, created with the help of pervasive computing technologies. Lifelog technologies would record and store everyday conversations, actions, and experiences of their users, enabling future replay and aiding remembrance. Products to assist lifelogging are already on the market; but the technology that will enable people fully and continuously to document their entire lives is still in the research and development phase. For generals, edgy artists and sentimental grandmothers alike, lifelogging could someday replace or complement, existing memory preservation practices. Like a traditional diary, journal or day-book, the lifelog …
