EFFECTS OF D‐AMPHETAMINE IN A TEMPORAL DISCRIMINATION PROCEDURE: SELECTIVE CHANGES IN TIMING OR RATE DEPENDENCY?

Two experiments evaluated rate dependency and a neuropharmacological model of timing as explanations of the effects of amphetamine on behavior under discriminative control by time. Four pigeons pecked keys during 60-trial sessions. On each trial, the houselight was lit for a particular duration (5 to 30 s), and then the key was lit for 30 s. In Experiment 1, the key could be lit either green or blue. If the key was lit green and the sample was 30 s, or if the key was lit blue and the sample was 5 s, pecks produced food on a variable-interval 20-s schedule. The rate of key pecking increased as a function of sample duration when the key was green and decreased as a function of sample duration when the key was blue. Acute d-amphetamine (0.1 to 3.0 mg/kg) decreased higher rates of key pecking and increased lower rates of key pecking as predicted by rate dependency, but did not shift the timing functions leftward (toward overestimation) as predicted by the neuropharmacological model. These results were replicated in Experiment 2, in which the key was lit only one color during sessions, indicating that the effects were not likely due to disruption of discriminative control by key color. These results are thus consistent with rate dependency but not with the predictions of the neuropharmacological model. 相似文献

We examined the utility of social cognitive variables in the longitudinal prediction of academic persistence and success of engineering students. The participants, 908 students enrolled in engineering majors at two state universities, completed measures of academic support, self-efficacy, outcome expectations, interests, satisfaction, positive affect, and intended persistence at the end of each of their first four semesters. In the current study, students' first and second semester responses were used to predict persistence and grade performance in engineering by the end of six semesters. Path analytic findings indicated that second-semester persistence intentions, satisfaction with the major, self-efficacy, and social support each produced direct paths to persistence. Objective ability (mathematics SAT scores), outcome expectations, and interests were linked to persistence indirectly via their relations to other variables in the model. In addition, self-efficacy and objective ability jointly predicted grade performance. Results were stable across gender and racial/ethnic groups. Implications for research and practice on academic adjustment in engineering are considered. 相似文献

This study explores differential processing of vocal and instrumental rhythms in short-term memory with three decision (same/different judgments) and one reproduction experiment. In the first experiment, memory performance declined for delayed versus immediate recall, with accuracy for the two rhythms being affected differently: Musicians performed better than non-musicians on clapstick but not on vocal rhythms, and musicians were better on vocal rhythms in the same than in the different condition. Results for the second experiment showed that concurrent sub-vocal articulation and finger-tapping differentially affected the two rhythms and same/different decisions, but produced no evidence for articulatory loop involvement in delayed decision tasks. In a third experiment, which tested rhythm reproduction, concurrent sub-vocal articulation decreased memory performance, with a stronger deleterious effect on the reproduction of vocal than of clapstick rhythms. This suggests that the articulatory loop may only be involved in delayed reproduction not in decision tasks. The fourth experiment tested whether differences between filled and empty rhythms (continuous vs. discontinuous sounds) can explain the different memorisation of vocal and clapstick rhythms. Though significant differences were found for empty and filled instrumental rhythms, the differences between vocal and clapstick can only be explained by considering additional voice specific features. 相似文献

System‐justifying behaviors: When feeling dependent on a system triggers gender stereotype‐consistent academic performance

Based on system‐justification theory, we hypothesized that men and women would perform in accordance with gender stereotypes mainly when justification of the system is necessary. In this research, system‐justification motivation was triggered using a system‐dependency manipulation. Study 1 shows that when feeling highly (vs. less) dependent on the system, people endorsed system‐justifying beliefs more. In Study 2, men performed better in math than in verbal domains, while women showed the reverse pattern, but only when they felt highly dependent on the system. Similar results were obtained on performance self‐evaluation. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

Starting from the observation that small children can count more objects than numbers—a phenomenon that I am calling the “lifeworld
dependency of cognition”—and an analysis of finger calculation, the paper shows how learning can be explained as the development
of cognitive systems. Parts of those systems are not only an individual’s different forms of knowledge and cognitive abilities,
but also other people, things, and signs. The paper argues that cognitive systems are first of all semiotic systems since
they are dependent on signs and representations as mediators. The two main questions discussed here are how the external world
constrains and promotes the development of cognitive abilities, and how we can move from cognitive abilities that are necessarily
connected with concrete situations to abstract knowledge.

Clinical fear of spiders was assessed in 39 patients before and after exposure treatment and at a 3-month follow-up. The assessment included behavioral, physiological and self-report measures. Some patients were tested in the treatment context (group Same), while others were tested in a different context (group Different). Both groups demonstrated a significant fear reduction from pre- to post-treatment in all measures, which persisted at the 3-month follow-up. Contrary to our expectations, no clear difference was observed between the groups at any moment. However, a 1-year follow-up test of the self-report measure revealed a return of fear in group Same, but not in group Different. These results show (1) that the effects of exposure treatment persisted over contexts and time in the short term, and (2) that conducting treatment and tests in different contexts enhanced efficiency of exposure treatment in the long term. 相似文献

Patients with chronic fatigue syndrome (CFS) frequently report chronic pain symptoms. Cognitive behavioural therapy (CBT) for CFS results in a reduction of fatigue, but is not aimed at pain symptoms. In this study, we tested the hypothesis that a successful treatment of CFS can also lead to a reduction of pain. The second objective was to explore possible mechanisms of changes in pain. The third objective was to assess the predictive value of pain for treatment outcome. Data from two previous CBT studies were used, one of adult CFS patients (n=96) and one of adolescent CFS patients (n=32). Pain severity was assessed with a daily self-observation list at baseline and post-treatment. The location of pain in adults was assessed with the McGill Pain Questionnaire (MPQ). Patients were divided into recovered and non-recovered groups. Recovery was defined as reaching a post-treatment level of fatigue within normal range. Recovered adult and adolescent CFS patients reported a significant reduction of pain severity compared to non-recovered patients. Recovered adult patients also had fewer pain locations following treatment. The decrease in fatigue predicted the change in pain severity. In adult patients, a higher pain severity at baseline was associated with a negative treatment outcome. 相似文献

The original concepts psychological hurt and therapeutic catharsis are proposed as the basis for a revolutionary change in the theory and practice of psychotherapy. Psychological hurt, understood as any residual interference with psychological functioning from an adverse event(s), is proposed as the irreducible cause of any such difficulty. Therapeutic catharsis is proposed as the optimal healing process for psychological hurt. Such a transformational view of the theory and practice of psychotherapy is deemed as necessary because of the lack of unequivocal answers to the following fundamental questions: What causes psychological problems? What resolves them in the most optimal way? 相似文献
