Four pigeons were trained on concurrent variable-interval schedules programmed on a center response key, with access to those schedules controlled by responses on left or right side keys. Two procedures were used. In one, the pigeon was given limited access, in that each side-key response produced 3-s access to a center-key schedule, and in the other procedure, access was unlimited. Data were analyzed using the generalized matching law. Comparison of sensitivities to reinforcement of interchangeover time for both procedures showed them to be of similar magnitude. Response sensitivities were also similar in magnitude for both procedures. From the limited-access procedure a second time measure that was available, switched-in time, was relatively uncontaminated by time spent emitting behavior other than key pecking. Sensitivities to reinforcement for the switched-in time measure were always smaller than interchangeover-time sensitivities for either procedure, and were approximately equal to response sensitivities for the limited-access procedure. Two other access times (5 and 7.5 s) were studied to validate the choice of 3 s as the main access time. These results indicate that when time spent emitting other behavior is excluded from interchangeover time, time and response sensitivities will be approximately equal. 相似文献

This investigation provides a preliminary examination of the difference between programmed and obtained reinforcement rates and its potential influence during treatment of aggression in a natural setting. Following a functional analysis that suggested that the aggression of a boy with autism was negatively reinforced, intervention was implemented by the boy's mother. Concurrent fixed-ratio (FR) 1 FR 1 schedules of escape were arranged for manding and aggression. When mands failed to compete effectively with aggression, obtained reinforcement ratios were calculated; these indicated that obtained reinforcement varied from the programmed schedule for aggression but not for mands. Increasing the rate of prompts for mands resulted in an increase in mands and a decrease in aggression to near-zero levels. 相似文献

The dot probe task is a widely used measure of attention allocation to threatening stimuli. The present two studies examine the reliability of different versions of this task using words as well as pictures as stimulus material. Estimates of both internal consistency and retest reliability over one week lead to the conclusion that the dot probe task is a completely unreliable measure of attentional allocation in non‐clinical samples. This unreliability may explain the inconsistent findings for the dot probe task as reported in the literature. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Burgeoning external threats to confidentiality by claims to clinical information create unprecedented challenges for psychoanalysts. Internal threats arise from the use of clinical material for educational, scientific and historical purposes. Traditionally, confidentiality is considered a patient's right and an analyst's obligation; privacy is not usually stated as a professional requirement. Little consideration has been given to the impact of the confidentiality and privacy dilemmas that analysts encounter throughout their careers. There has been no systematic examination of the confidentiality policies of psychoanalytic organizations, nor has their role in facilitating maintenance of patient confidentiality and analysts' privacy been made explicit. The research reported here was undertaken to address these issues and to obtain baseline information about the current confidentiality policies and practices of psychoanalytic organizations in three English-speaking countries (Britain, Canada and the USA). The author discusses survey results in the light of the challenges which arise at each phase of the analytic career. She makes suggestions as to how psychoanalytic organizations can and should facilitate analysts' resolutions of contemporary confidentiality and privacy dilemmas. 相似文献

Different modes of psychotherapy can be an effective form of treatment for a range of mental health problems. Psychotherapy provision in the NHS is organised in a variety of ways, with patient entry to various modes of therapy determined by a range of factors including evidence‐based guidelines and patient or referrer preference. The methods by which patients arrive at a particular mode of psychotherapy are largely unreported. This paper aims to describe this process in one UK NHS psychotherapy service offering cognitive behavioural and psychoanalytic psychotherapy, and provides data to inform a discussion on the theoretical congruence of these allocation decisions. 相似文献

Trait Intellect, one of the two ‘aspects’ of the broader Openness/Intellect ‘domain’, predicts performance on a range of cognitive tasks including tests of intelligence and working memory. This has been explained in terms of the tendency for high‐Intellect individuals to explore, or engage more effortfully with, abstract information. This theoretical perspective can be framed in the language of Resource Allocation Theory, in terms of high‐Intellect individuals allocating more of their available cognitive resources to abstract cognitive tasks. In two experiments (total N = 160), we examined the relation between Intellect and cognitive engagement during a primary word‐search task under conditions of both high and low secondary cognitive load. Both experiments revealed that high‐Intellect individuals were more vulnerable to the impact of the secondary cognitive load on primary task performance. This suggests that, under low secondary load, such individuals were indeed allocating more of their available cognitive resources to the primary task. These results held after controlling for trait Openness, trait Industriousness (an aspect of Conscientiousness) and a measure of working memory capacity (N‐back task). Our findings provide novel support for the cognitive mechanisms proposed to underlie trait Intellect. Copyright © 2016 European Association of Personality Psychology 相似文献

An optimal asset allocation is crucial for nonlife insurance companies. The most previous studies focused on this topic use a mono‐objective technique optimization. This technique usually allows the maximization of shareholders' expected utility. As nonlife insurance company is a complex system, it has many stakeholders other than shareholders. So, the satisfaction of the shareholders' expected utility cannot lead usually to the satisfaction of other stakeholders' objectives. Therefore, the focus on utility maximization can be a destruction source of other objectives such as productivity, competitiveness and solvency. Our developed model integrates simulation approach with a multiobjective particle swarm optimization algorithm. This model insures an optimal asset allocation that maximizes, simultaneously, shareholders expected utility and technical efficiency of European nonlife insurance companies. The empirical application conducts a comparison between the attained results with multiobjective optimization technique and mono‐objective technique to search the optimal asset allocation for nonlife insurance companies. Our results show that the investment portfolio will be more diversified between most available investment assets. In addition, any decision maker should take account of different stakeholders' objectives. Accordingly, multiobjective optimization allows us to find the best asset allocation that maximizes simultaneously expected utility and technical efficiency of nonlife insurance companies.
