Post-learning sleep is beneficial for human memory. However, it may be that not all memories benefit equally from sleep. Here, we manipulated a spatial learning task using monetary reward and performance feedback, asking whether enhancing the salience of the task would augment overnight memory consolidation and alter its incorporation into…

Surgical disconnection of the frontal cortex and inferotemporal cortex severely impairs many aspects of visual learning and memory, including learning of new object-in-place scene memory problems, a monkey model of episodic memory. As part of a study of specialization within prefrontal cortex in visual learning and memory, we tested monkeys with…

Two experiments were designed to replicate and extend previous findings on the transformation of avoidance response functions in accordance with the relational frames of Same and Opposite. Participants were first exposed to non-arbitrary and arbitrary relational training and testing. Next, during avoidance conditioning, one stimulus from the…

Results of a study of the effects of negative criticism indicated that group criticism reduces the cognitive performance of college students. (DR)

This article offers a reformulation of the negative reinforcement model of drug addiction and proposes that the escape and avoidance of negative affect is the prepotent motive for addictive drug use. The authors posit that negative affect is the motivational core of the withdrawal syndrome and argue that, through repeated cycles of drug use and…

The influence of an individual's cognitive style on hypothesis testing behavior was investigated. Thirty analytic and 30 global subjects each solved 24, 16-trial problems with intermittent reinforcement, i.e., E said "right" or "wrong" after every fifth response. Results indicated that the analytic subjects solved more problems…

Six experiments examined the problem-solving behavior of normal and mentally retarded (MR) children with a two-choice discrimination learning situation: the effects of stimulus similarity upon types of solutions utilized by MR children; the role of redundant cues in the discrimination learning of MR subjects with differing mental ages; the…
