Effects of posttraining reinforcement upon retention of a passive avoidance task

TLDR
The results do not support the hypothesis of Huston, Mondadori, and Waser (1974) that posttraining stimuli directly reinforce memory processing.

Facilitation of memory processing by posttrial morphine: Possible involvement of reinforcement mechanisms?

TLDR
The data are discussed in connection with the hypothesis that morphine acts directly on reinforcement mechanisms by activating the opiate receptor, and the 100 mg/kg dose level resulted in memory facilitation.

Facilitation or inhibition of memory by morphine: a question of experimental parameters

TLDR
It was found that post-trial administration of medium and relatively high doses of morphine facilitate retention performance following moderate levels of foot-shock, while under other conditions of dose and shock intensity, the drug was not effective or even impaired retention.

Effect of posttraining exposure to an aversive stimulus on retention

TLDR
The conclusion that an aversive, or negatively reinforcing, event can improve retention in a retroactive, noncontingent manner is made.

Conditioned Memory Modulation, Freezing, and Avoidance as Measures of Amygdala-Mediated Conditioned Fear

TLDR
The findings suggest that the central and medial nuclei of the amygdala may be important parts of neural circuits mediating conditioned responses that constitute conditioned aversive states, but that conditioned freezing may be mediated independently.

Memory enhancement produced by post-training exposure to sucrose-conditioned cues

TLDR
It is shown for the first time that post-training exposure to conditioned stimuli previously paired with consumption of a sucrose solution also enhances memory consolidation.

Amnesic and Punishing Effects of Electroconvulsive Shock

Rats learned to avoid a place where they were repeatedly given electroconvulsive shock treatments, but the learning was slow in comparison with that obtained with subconvulsive shock. Convulsive

Long Temporal Gradient of Retrograde Amnesia for a Well-Discriminated Stimulus

TLDR
A temporal gradient of elec- troconvulsive shock-produced retrograde amnesia, extending up to at least 1 hour, for a well-discriminated stimulus, was demonstrated in mice in a one-trial learning passive avoidance situation.

Reinforcement Magnitude as a Determinant of Performance Decrement after Electroconvulsive Shock

The intensity of a foot shock may be a determinant of the rate at which an avoidance response becomes resistant to disruption by electroconvulsive shock. Mice were trained, one trial a day, in a

Short footshock-electroconvulsive shock intervals and retrograde amnesia in mice

TLDR
Since the 2-sec and 4-sec groups showed test latencies lower than their training STLs, a “proactive effect” interpretation seems more acceptable than one appealing to hypothesis of memory consolidation.

Permanence of Retrograde Amnesia Produced by Electroconvulsive Shock

TLDR
The permanence of retrograde amnesia produced for a single training trial by a single electroconvulsive shock was studied and permanent effects were found to be permanent with retention intervals as long as 1 month.
