Undergraduate students' presses on left and right buttons occasionally made available points exchangeable for money. Blue lights over the buttons were correlated with multiple random-ratio random-interval components; usually, the random-ratio schedule was assigned to the left button and the random-interval to the right. During interruptions on the multiple schedule, students filled out sentence-completion guess sheets (e.g., The way to earn points with the left button is to...). For different groups, guesses were shaped with differential points also worth money (e.g., successive approximations to “press fast” for the left button), or were instructed (e.g., Write “press slowly” for the left button), or were simply collected. Control of rate of pressing by guesses was examined in individual cases by reversing shaped or instructed guesses, by instructing pressing rates, and/or by reversing multiple-schedule contingencies. Shaped guesses produced guess-consistent pressing even when guessed rates opposed those characteristic of the contingencies (e.g., slow random-ratio and fast random-interval rates), whereas guesses and rates of pressing rarely corresponded after unsuccessful shaping of guesses or when guessing had no differential consequences. Instructed guesses and pressing were inconsistently related. In other words, when verbal responses were shaped (contingency-governed), they controlled nonverbal responding. When they were instructed (rule-governed), their control of nonverbal responding was inconsistent: the verbal behavior sometimes controlled, sometimes was controlled by, and sometimes was independent of the nonverbal behavior. 相似文献

This paper describes a family who had been known to the professional caring agencies for some five years. At the time of treatment, the family had fifteen-year old twin sons whose frequently aggressive behaviour was the focus of the referred problem. It was agreed that the author would attempt to work with this family should they be re-referred, with a view to offering an alternative mode of treatment. A structural framework of therapy was tried, but very shortly therapeutic attempts to help solve the problems were assimilated by the family and seemed to serve only to ensure their continuation. At this point, a powerful paradoxical intervention was tried in order to free both family and therapists from perpetuating a 'more of the same'. This tactic allowed time for treatment from a more structural base to continue. In this context, consideration is given to the nature of pathological and therapeutic double binding. Some of the difficulties inherent in attempting new methods of treatment from within a traditional casework setting with its statutory responsibilities are also discussed. 相似文献

This experiment assessed the effect of an emotional pictorial input on the processing of preceding and succeeding pictorial inputs. Thirty-nine individual pictures were successively presented for 165 msec, with a 500-msec dark interval between each item. The 20th input item was either an emotional or a neutral picture; the remaining 38 items were neutral sketches. Postinput recognition data indicated a processing disruption of several pictorial items following the emotional as compared to the neutral input and a possible processing disruption of the item immediately preceding the emotional stimulus. The outcome suggests nonindependence in the processing of separate picture inputs in rapid sequential presentations. 相似文献

This paper considers some of the pitfalls of a single-model approach to family therapy. It does not argue a 'right' way of practising family therapy, but proposes that the therapist needs to have available a range of approaches on which to draw. This also raises certain problems for training in family therapy, which are highlighted. A case is discussed in the light of a number of perspectives, to demonstrate how approaches can be used in complementary fashion. Finally, reference is made to some of the agency constraints which also make it difficult to practise any one model in a 'pure' form. 相似文献

Associations between uncoupling protein (UCP) expression and functional changes in myocardial mitochondrial bio-energetics have not been well studied during periods of starvation stress. Our aim was to study the effects of acute starvation, for 24 or 48 h, on combined cardiac mitochondrial function and UCP expression in mice. Isolated heart mitochondria from female mice starved for 48 h compared to that from mice fed revealed a significantly (p < 0.05) decreased adenosine diphosphate-to-oxygen ratio, a significantly increased proton leak and an increased GTP inhibition on palmitic acid-induced state 4 oxygen consumption (p < 0.05). These bio-energetic functional changes were associated with increases in mitochondrial UCP2 and UCP3 protein expression. In conclusion, our findings suggest that increased UCP2 and UCP3 levels may contribute to decreased myocardial mitochondrial bio-energetic function due to starvation. 相似文献

Use of unmanned aerial vehicles (UAVs) is an increasingly important element of military missions. However, controlling UAVs
may impose high stress and workload on the operator. This study evaluated the use of the RoboFlag simulated environment as
a means for profiling multiple dimensions of stress and workload response to a task requiring control of multiple vehicles
(robots). It tested the effects of two workload manipulations, environmental uncertainty (i.e., UAV’s visual view area) and
maneuverability, in 64 participants. The findings confirmed that the task produced substantial workload and elevated distress.
Dissociations between the stress and performance effects of the manipulations confirmed the utility of a multivariate approach
to assessment. Contrary to expectations, distress and some aspects of workload were highest in the low-uncertainty condition,
suggesting that overload of information may be an issue for UAV interface designers. The strengths and limitations of RoboFlag
as a methodology for investigating stress and workload responses are discussed. 相似文献
