The experimental analysis of delay of reinforcement is considered from the perspective of three questions that seem basic not only to understanding delay of reinforcement, but, also, by implication, the contributions of temporal relations between events to operant behavior. The first question is whether effects of the temporal relation between responses and reinforcers can be isolated from other features of the environment that often accompany delays, such as stimuli or changes in the temporal distribution or rate of reinforcement. The second question is that of the effects of delays on operant behavior. Beyond the common denominator of a temporal separation between reinforcers and the responses that produce them, delay of reinforcement procedures differ from one another along several dimensions, making delay effects circumstance dependent. The final question is one of interpreting delay of reinforcement effects. It centers on the role of the response—reinforcer temporal relation in the context of other, concurrently operating behavioral processes. 相似文献

Tafarodi, R. W., Wild, N. & Ho, C. (2010). Parental authority, nurturance, and two‐dimensional self‐esteem. Scandinavian Journal of Psychology. This study examined the relations of parental permissiveness, authoritativeness, authoritarianism, and nurturance with two dimensions of self‐esteem – self‐liking and self‐competence. In a sample of 207 two‐parent families, university students and both their parents provided independent reports on all the above variables. Covariance structure analysis was used to eliminate reporter‐specific bias and unreliability in predicting student self‐esteem from parenting behavior. The results revealed highly redundant positive associations of mothers’ and fathers’ authoritativeness and nurturance with both self‐liking and self‐competence. The pattern of these associations suggests that the significance of parental authoritativeness for the child’s self‐esteem is due mainly to the nurturance it provides. Contrary to expectation, mothers’ and fathers’ authoritarianism was also positively associated with self‐liking. As discussed, however, this is likely to be an artifact of the specific measures and testing methods used. 相似文献

A conceptual integration and review are presented of three separate research programmes informed by the theory of lay epistemics (Kruglanski, 1989). They respectively address the “why”, “how”, and “who” questions about human knowledge formation. The “why” question is treated in work on the need for cognitive closure that propels epistemic behaviour and affects individual, interpersonal, and group phenomena. The “how” question is addressed in work on the unimodel (Kruglanski, Pierro, Mannetti, Erb, & Chun, 2007) depicting the process of drawing conclusions from the “information given”. The “who” question is addressed in work on “epistemic authority” highlighting the centrality of source effects (including oneself as a source) in human epistemic behaviour. These separate research paradigms explore facets of epistemic behaviour that jointly produce human knowledge, of essential significance to people's’ individual and social functioning. 相似文献

This study examined the role of temporal orientation and affective frame in the execution of ethical decision-making strategies. In reflecting on a past experience or imagining a future experience, participants thought about experiences that they considered either positive or negative. The participants recorded their thinking about that experience by responding to several questions, and their responses were content-analyzed for the use of ethical decision-making strategies. The findings indicated that a future temporal orientation was associated with greater strategy use. Likewise, a positive affective frame was associated with greater strategy use. Future orientation may permit better strategy execution than a past orientation because it facilitates more objective, balanced contemplation of the reflected-upon situation and minimizes potential self-threat associated with past behavior. A positive affective frame likely improves strategy execution because it facilitates active analysis of the experience. Future directions and implications of these findings are discussed. 相似文献

In an experiment on the effect of intensity accents on the perception of time intervals between tones. H. G. Tekman (2001) found that the regular placement of deviant time intervals in short sequences of tones reduced detection, especially if intensity accents marked the deviant time intervals. That was the opposite of what one wòuld have expected on the basis of the dynamic attending theory of M. R. Jones (1976). The effect might have occurred because temporally deviant tones create cumulative onset shifts that affect all the subsequent tones. If the deviations were randomly placed, then they could follow each other in close succession and change the local tempo. In the present study, the changes of local tempo, which might have acted as a cue for the detection of temporal deviations in the random sequences, were eliminated by compensating for deviant time intervals with equal deviations in the opposite direction in the interval that followed. That change in the stimuli eliminated the negative main effect of regularity, and the accenting interacted with regularity in favor of detection in the regular sequences. However, a simple advantage of regular over random sequences was not observed. The author discusses possible reasons for the lack of a facilitatory effect of regularity. 相似文献

ResumenEl objetivo de esta investigación ha sido someter a prueba en un mismo diseño las variables representativas de cada uno de los tres principales modelos contemporáneos que tratan de explicar la experiencia humana sobre la duración. Además, se ha efectuado una comparación entre los paradigmas experimentales prospectivo y retrospectivo igualados en el tiempo que transcurre hasta la realización del juicio, así como una medición directa mediante un índice independiente del esfuerzo cognitivo involucrado en la realización de las tareas experimentales. El experimento realizado ha sido aplicado a 192 estudiantes de Psicología de la Universidad de Salamanca. Los resultados muestran que cuando se atiende de forma intencional al tiempo, los cambios ocurridos en el contexto cognitivo son utilizados como los indicios primordiales para la configuración de los juicios de tiempo más precisos. Sin embargo, cuando la atención al tiempo es tan sólo incidental, el esfuerzo cognitivo es el factor que mejor explica la estimación temporal mediante una relación inversa con el tamaño de la reproducción efectuada. 相似文献

Intertemporal tradeoffs are ubiquitous in decision making, yet preferences for current versus future losses are rarely explored in empirical research. Whereas rational‐economic theory posits that neither outcome sign (gains vs. losses) nor outcome magnitude (small vs. large) should affect delay discount rates, both do, and moreover, they interact: in three studies, we show that whereas large gains are discounted less than small gains, large losses are discounted more than small losses. This interaction can be understood through a reconceptualization of fixed‐cost present bias, which has traditionally described a psychological preference for immediate rewards. First, our results establish present bias for losses—a psychological preference to have losses over with now. Present bias thus predicts increased discounting of future gains but decreased (or even negative) discounting of future losses. Second, because present bias preferences do not scale with the magnitude of possible gains or losses, they play a larger role, relative to other motivations for discounting, for small magnitude intertemporal decisions than for large magnitude intertemporal decisions. Present bias thus predicts less discounting of large gains than small gains but more discounting of large losses than small losses. The present research is the first to demonstrate that the effect of outcome magnitude on discount rates may be opposite for gains and losses and also the first to offer a theory (an extension of present bias) and process data to explain this interaction. The results suggest that policy efforts to encourage future‐oriented choices should frame outcomes as large gains or small losses. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Despite often showing behaviorally typical levels of social cognitive ability, unaffected siblings of children with autism spectrum disorder have been found to show similar functional and morphological deficits within brain regions associated with social processing. They have also been reported to show increased activation to biological motion in these same regions, such as the posterior superior temporal sulcus (pSTS), relative to both children with autism and control children. It has been suggested that this increased activation may represent a compensatory reorganization of these regions as a result of the highly heritable genetic influence of autism. However, the response patterns of unaffected siblings in the domain of action perception are unstudied, and the phenomenon of compensatory activation has not yet been replicated. The present study used functional magnetic resonance imaging to determine the neural responses to intentional biological actions in 22 siblings of children with autism and 22 matched controls. The presented actions were either congruent or incongruent with the actor’s emotional cue. Prior studies reported that typically developing children and adults, but not children with autism, show increased activation to incongruent actions (relative to congruent), within the pSTS and dorsolateral prefrontal cortex. We report that unaffected siblings did not show a compensatory response, or a preference for incongruent over congruent trials, in any brain region. Moreover, interaction analyses revealed a sub-region of the pSTS in which control children showed an incongruency preference to a significantly greater degree than siblings, which suggests a localized deficit in siblings. A sample of children with autism also did not show differential activation in the pSTS, providing further evidence that it is an area of selective disruption in children with autism and siblings. While reduced activation to both conditions was unique to the autism sample, lack of differentiation to incongruent and congruent intentional actions was common to both children with ASD and unaffected siblings. 相似文献

AbstractIn his Anglica Historia, the expatriate Italian cleric, Polydore Vergil (1470–1555), cultivated a flexible and resourceful relationship with ecclesiastical and temporal authorities in Henrician and Edwardine England when residing there. His humanist learning enabled him to adapt to changes of power and religion by means of a prudent publishing strategy, to challenge with a degree of impunity the perceived wisdom of both kings and clerics, and to carry out revenge upon one who had wronged him: Cardinal Wolsey. Using primary and secondary source material, this article examines, for the first time, Vergil’s attitude to and dealings with those in authority through an assessment of his Anglica Historia. Dying a Roman Catholic in his native Italy, ‘Polydorus Italus’ adjudged the Henrician Reformation, in so far as he actually presents it, as deficient. 相似文献

I examine some recent claims put forward by L. A. Paul, Barry Dainton and Simon Prosser, to the effect that perceptual experiences of movement and change involve an (apparent) experience of ‘passage’, in the sense at issue in debates about the metaphysics of time. Paul, Dainton and Prosser all argue that this supposed feature of perceptual experience – call it a phenomenology of passage – is illusory, thereby defending the view that there is no such a thing as passage, conceived of as a feature of mind-independent reality. I suggest that in fact there is no such phenomenology of passage in the first place. There is, however, a specific structural aspect of the phenomenology of perceptual experiences of movement and change that can explain how one might mistakenly come to the belief that such experiences do involve a phenomenology of passage. 相似文献
