Behavioral stress has detrimental effects on subsequent cognitive performance in many species, including humans. For example, humans exposed to stressful situations typically exhibit marked deficits in various learning and memory tasks. However, the underlying neural mechanisms by which stress exerts its effects on learning and memory are unknown. We now report that in adult male rats, stress (i.e., restraint plus tailshock) impairs long-term potentiation (LTP) but enhances long-term depression (LTD) in the CA1 area of the hippocampus, a structure implicated in learning and memory processes. These effects on LTP and LTD are prevented when the animals were given CGP39551 (the …

In Experiment 1, mildly depressed (dysphoric) and nondysphoric subjects tried to solve logic, problems that were analogous to subsequent target problems; then they attempted target solutions with or wit hour hints in the form of the analogues' themes. Target solutions were impaired by the hints in the nondysphoric group alone. Experiment 2A was a no-training control to verify that transfer did indeed occur. In Experiment 2B, all subjects received hints in the transfer phase; the training phase was either problem oriented (as in Experiment 1) or memory oriented. Again, nondysphoric subjects solved fewerproblems following problem-oriented training than did both dysphoric …
Practical Aspects Of Emotion And Memory, Paula T. Hertel
Practical Aspects Of Emotion And Memory, Paula T. Hertel
Psychology Faculty Research
Can anyone doubt that the study of emotion and memory should have practical implications? Surely not those among us who have had emotional experiences and sometimes try to forget them, to remember them, or to remember other things while having them. Extreme examples include the witness to a robbery and the victim of abuse. Less dramatically but far more commonly, anxious or depressed people perform everyday acts that are memory dependent. Indeed, a practical or useful science of memory should have a great deal to say about how memory works under such emotional conditions.
