Rats were trained in an operant discrimination involving two panel lights, A and B. Group CI (Conditioned Inhibition) was trained to lever press in the presence of A (S+), and not in the presence of the compound AB (S?). The opposite contingencies held in Group CE (Conditioned Excitation). Response rates were higher in Group CE than in Group CI, especially to the positive stimulus. However, the groups acquired the discrimination at comparable rates. In a separate phase of the experiment, a tone (C) was separately trained in the absence of the lights to control responding. All seven possible combinations of A, B, and C were then presented randomly during extinction. The inhibitory effect of B on C in Group CI was comparable in magnitude to the excitatory effect of B on C in Group CE. B's effect on C was not altered by the presence or absence of A, regardless of whether A was inhibitory or excitatory. The symmetry between CI and CE revealed by the stimulus-compounding test may be partly artifactual. 相似文献

After receiving a sample shock, subjects in a Threat Condition were told that they would receive additional painful shocks while subjects in a Nonthreat Condition were not threatened with additional shocks. Subjects in an Attentional Diversion Condition were then instructed to read and think about an amusing story, subjects in a Situation Redefinition Condition were instructed to write down reasons why they should not be afraid in this situation, and subjects in a Control Condition were not given any instructions for coping with stress. (Coping Conditions were factorially crossed with Threat Conditions and 192 subjects were employed.) Physiological measures (pulse rate, finger pulse volume, skin resistance) indicated that unlike the results of previous research, attentional diversion was effective in reducing stress but situation redefinition was not. Discussion was focused on the parameters which determine whether or not a coping strategy will be effective. 相似文献

Recent studies on information processing have developed an alternative model of mental abilities which constitutes an integration of Russian clinical research and North American factor analytic research. This model proposes that information may be processed in a simultaneous synthesis or a successive synthesis. The present study examines variations in these syntheses in three intelligence groups in order to identify the types of information processing characteristic of different intelligence groups. A stratified sampling of verbal and nonverbal IQ was used to select 60 boys of age 9–10 in each of three verbal IQ ranges: 71–90, 91–110, and 111–130. A battery of tests used in previous research was administered to all subjects. Multivariate analyses of variance and discriminant analyses indicated that the IQ groups differed markedly on tests used to identify simultaneous synthesis, most notably Raven's Progressive Matrices, and differed slightly less on tests of successive synthesis. Factor analyses of the test intercorrelations for each group revealed more factorial invariance across the IQ groups than had been suggested by a previous exploratory study. It was concluded that strong individual differences exist in simultaneous and successive syntheses over the major portion of the standardized intelligence range, and no high degree of specialization of information processing was characteristic of an intelligence group. 相似文献

Intensive Transactional Analysis Psychotherapy (ITAP) is a new therapeutic approach based on the integration of Transactional Analysis and brief psychodynamic approaches. ITAP is based on two key therapeutic tools—the intrapsychic triangle and the interpersonal triangle—which the therapist uses to focus patients’ attention on moment‐by‐moment therapy processes. The aim of the present study was to provide early empirical documentation of ITAP effectiveness. To this aim, six patients (four females, two males) were longitudinally evaluated using an A‐B‐A mixed quantitative and qualitative design, with evaluations at Baseline, Treatment and Follow‐up phases. Each patient received 16 50‐min weekly sessions of ITAP therapy over 4 months. For quantitative evaluations, patients filled out the Clinical Outcome in Routine Evaluation‐Outcome Measure (CORE‐OM) at each evaluation. Effects size values were estimated to evaluate quantitative changes comparing mean scores of Baseline, Treatment and Follow‐up phases. At the first follow‐up, the Change Interview was used to qualitatively evaluate patients’ perceived changes. In the quantitative data, four of the six patients reported a very good outcome, with large to very large effect sizes in Baseline versus Treatment and/or Baseline versus Follow‐up scores comparisons, whereas two patients reported variable fluctuations within the non‐clinical range of outcome scores. In the qualitative evaluations, all patients reported several moderately to extremely important perceived changes attributed to psychotherapy. 相似文献

The article discusses two important influences of B. F. Skinner, and later workers in the behavior-analytic tradition, on the study of animal timing. The first influence is methodological, and is traced from the invention of schedules imposing temporal constraints or periodicities on animals in The Behavior of Organisms, through the rate differentiation procedures of Schedules of Reinforcement, to modern temporal psychophysics in animals. The second influence has been the development of accounts of animal timing that have tried to avoid reference to internal processes of a cognitive sort, in particular internal clock mechanisms. Skinner's early discussion of temporal control is first reviewed, and then three recent theories-Killeen & Fetterman's (1988) Behavioral Theory of Timing; Machado's (1997) Learning to Time; and Dragoi, Staddon, Palmer, & Buhusi's (2003) Adaptive Timer Model-are discussed and evaluated. 相似文献

In response to my "How to Make Naturalism Safe for Supernaturalism: An Evaluation of Willem Drees's Supernaturalistic Naturalism" (Rottschaefer 2001), Willem Drees maintains that I have misunderstood his purpose and views and have failed to make the case against his view that naturalism is intrinsically limited. In this response, I comment on these concerns. 相似文献

In the present study the effects of a wide range of doses of the dopamine release inhibitor CGS 10746B were evaluated in spontaneous activity and in aggressive behaviour using the paradigm of isolation‐induced aggression. The two higher doses (8 and 16 mg/kg) produced a decrease in spontaneous motor activity. Antiaggressive effects were observed after administration of doses from 4 mg/kg upwards. At this dose, CGS 10746B diminished threat and attack, and although an increase in immobility was observed, no impairment of other motor behaviours was presented. With higher doses, aggression was practically abolished but with a concomitant effect on many other behaviours. When animals were separated depending on their latency of attack, those that showed a long attack latency (LAL) presented a stronger response to 4 mg/kg than those that had a short attack latency (SAL), which were not affected in their aggression by this dose. We can conclude that presynaptic dopamine function is necessary for the normal expression of aggressive behaviours, since CGS 10746B reduces aggression at doses that do not affect spontaneous motor activity.
