This study examined if listener behavior and responding by exclusion would emerge after training 3 participants with autism to tact stimuli. Tacts for 2 of 3 stimuli were directly trained using discrete trial training methodology and were followed by an auditory-visual discrimination probe in which auditory-visual discrimination by naming (i.e.,…

In obsessive-compulsive disorder (OCD), functional behaviors such as checking that a door is locked become dysfunctional, maladaptive, and debilitating. However, it is currently unknown how aversive and appetitive motivations interact to produce functional and dysfunctional behavior in OCD. Here we show a double dissociation in the effects of…

Drugs of abuse cause changes in the prefrontal cortex (PFC) and associated regions that impair inhibitory control over drug-seeking. Breaking the contingencies between drug-associated cues and the delivery of the reward during extinction learning reduces rates of relapse. Here we used vagus nerve stimulation (VNS) to induce targeted synaptic…

Sign- and goal-tracking are differentially associated with drug abuse-related behavior. Recently, it has been hypothesized that sign- and goal-tracking behavior are mediated by different neurobehavioral valuation systems, including differential incentive salience attribution. Herein, we used different conditioned stimuli to preferentially elicit…

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…

In answering general-information questions, a within-person confidence-accuracy (C-A) correlation is typically observed, suggesting that people can monitor the correctness of their knowledge. However, because the correct answer is generally the consensual answer--the one endorsed by most participants--confidence judgment may actually monitor the…

Authors investigated the hypothesis that differences in aggressive behavior may partly be a function of differences (a) in the perception of aggressive cues, or (b) in the degree in which retaliation is expected. (Authors)

This study investigates schizophrenics' ability to utilize input organization and auditory cues for recall. The findings suggest that schizophrenics do utilize the cues of input organization and vocalization for recall, but the process of responding seems to engender excessive output interference which makes retrieval of late input items…

Investigates third- and fourth-grade children's verbal evaluations of syllables paired with different reward schedules (full, partial, or none) for "pleasantness" and "curiosity." (Author/ED)

This study examines the effects on long-term retention of variations in intensity and temporal parameters of arousal following a single learning trial in a paired-associate task. Intensity of arousal was manipulated by using two levels of noise, 75 db. and 90 db., and a condition without noise. Noise was delivered to the 56 female university…

Two experiments were conducted to examine self-fulfilling expectancy influence in a simulated supervisor-worker interaction. The first experiment led supervisor subjects to expect either high or low compliance from their workers. All workers completed a set of five tasks twice, once when instructed to work fast and once when instructed to work…
