Successive positive contrast in one-way avoidance learning.
The main finding of these experiments was a positive contrast effect in one-way avoidance learning. Experiment 1 showed that increasing safety time during one-way avoidance training led to improved performance, surpassing that of a control group that had received the high reward (safe time) from the beginning of training. Experiment 2 showed that a similar positive contrast effect occurred when...
متن کاملThe effects of scopolamine hydrobromide on one-way and two-way avoidance learning in rats.
-Previous studies have shown certain striking similarities between the behavioral effects produced by some anticholinergic drugs and the effects produced by hippocampal destruction. To investigate this parallel more thoroughly, scopolamine hydrobromide w a s administered to rats in one-way and two-way active avoidance learning situations. The drugged animals showed improved learning of the two-...
متن کاملContext-independent directional cue learning by hippocampal place cells.
In a symmetrical environment possessing no other polarizing visual cues, the spatially localized firing of hippocampal place cells can be primarily orientated by a reliable distal visual stimulus, such as a white cue card. However, if such a directional cue is made unreliable by being frequently moved in full view of the rat, the rat's internal sense of direction comes, over the course of a few...
متن کاملOne-trial-a-day avoidance learning
A one-trial-a-day discrete-trial avoidance conditioning procedure run for 30 consecutive days was compared with a massed-trial procedure where Ss received 30 consecutive trials within 1 day. The Ss in both groups were equated for time each S spent in the nonshock compartment of the apparatus, number of times the transport box carrying Ss was lifted out of the nonshock compartment, and the numbe...
متن کاملCue configuration effects in acquisition and extinction of a cocaine-induced place preference.
A pervasive finding in animal models of substance abuse is that associations form quickly between contexts and drugs of abuse, such as cocaine. Studies of conditioned place preference (CPP) demonstrate that animals approach cues previously paired with cocaine. This is a commonly used preparation, but the configuration of the CPP apparatus differs across laboratories. Two common apparatus config...
