Prominent models of attentional control assert a dichotomy between top-down and bottom-up control, with the former determined by current selection goals and the latter determined by physical salience. This theoretical dichotomy, however, fails to explain a growing number of cases in which neither current goals nor physical salience can account for strong selection biases. For example, equally salient stimuli associated with reward can capture attention, even when this contradicts current selection goals. Thus, although 'top-down' sources of bias are sometimes defined as those that are not due to physical salience, this conception conflates distinct--and sometimes contradictory--sources of selection bias. We describe an alternative framework, in which past selection history is integrated with current goals and physical salience to shape an integrated priority map. 相似文献

Envy is the unpleasant emotion that can arise when people are exposed to others with superior possessions. Common wisdom and scholarly opinion suggest that when people experience envy they may be motivated to obtain the others' superior possession. Despite the vast interpersonal, societal, and economical consequences attributed to this potential aspect of envious responding, experimental demonstrations of the affective and behavioral consequences of envy-inducing situations are scarce. We propose that social comparisons with better-off others trigger an impulsive envious response that entails a behavioral tendency to strive for their superior good. However, given that the experience of envy is painful, self-threatening, and met with social disapproval, people typically attempt to control their envious reactions. Doing so requires self-control capacities, so that envious reactions may only become apparent if self-control is taxed. In line with these predictions, four experiments show that only when self-control resources are taxed, upward comparisons elicit envy paired with an increased willingness to pay for, to spontaneously purchase and to impulsively approach the superior good. 相似文献

Welch’s (Biometrika 29: 350–362, 1938) procedure has emerged as a robust alternative to the Student’s t test for comparing the means of two normal populations with unknown and possibly unequal variances. To facilitate the advocated
statistical practice of confidence intervals and further improve the potential applicability of Welch’s procedure, in the
present article, we consider exact approaches to optimize sample size determinations for precise interval estimation of the
difference between two means under various allocation and cost considerations. The desired precision of a confidence interval
is assessed with respect to the control of expected half-width, and to the assurance probability of interval half-width within
a designated value. Furthermore, the design schemes in terms of participant allocation and cost constraints include (a) giving
the ratio of group sizes, (b) specifying one sample size, (c) attaining maximum precision performance for a fixed cost, and
(d) meeting a specified precision level for the least cost. The proposed methods provide useful alternatives to the conventional
sample size procedures. Also, the developed programs expand the degree of generality for the existing statistical software
packages and can be accessed at brm.psychonomic-journals.org/content/ supplemental. 相似文献

Holding an intention often interferes with other ongoing activities, indicating that resource-demanding processes are involved
in maintaining the intention and noticing the appropriate event to fulfill it. Little is known, however, about the nature
of the processes underlying this task interference effect. The goal of the present research was to decompose the processes
contributing to the task interference effect by applying the diffusion model (Ratcliff, Psychological Review 85:59–108, 1978) to an event-based prospective memory task. In the first experiment, we validated the interpretation of the response criterion
parameter (a) of the diffusion model as reflecting strategies to cope with the anticipated demands of a prospective memory task in the
context of the ongoing task. The second experiment served to investigate which underlying processes contribute to the task
interference often found with prospective memory tasks. Diffusion model analyses revealed that the task interference effect
was due to (1) less efficient processing in the more demanding than in the less demanding prospective memory task and (2)
a more conservative response criterion. We suggest that the anticipated demands and the additional processing demands of the
prospective memory task jointly contribute to the task interference effect. 相似文献

There is an ongoing controversy regarding the relationship between covert attention and saccadic eye movements. While there is quite some evidence that the preparation of a saccade is obligatory preceded by a shift of covert attention, the reverse is not clear: Is allocation of attention always accompanied by saccade preparation? Recently, a shifting and maintenance account was proposed suggesting that shifting and maintenance components of covert attention differ in their relation to the oculomotor system. Specifically, it was argued that a shift of covert attention is always accompanied by activation of the oculomotor program, while maintaining covert attention at a location can be accompanied either by activation or suppression of oculomotor program, depending on the probability of executing an eye movement to the attended location. In the present study we tested whether there is such an obligatory coupling between shifting of attention and saccade preparation and how quickly saccade preparation gets suppressed. The results showed that attention shifting was always accompanied by saccade preparation whenever covert attention had to be shifted during visual search, as well as in response to exogenous or endogenous cues. However, for the endogenous cues the saccade program to the attended location was suppressed very soon after the attention shift was completed. The current findings support the shifting and maintenance account and indicate that the premotor theory needs to be updated to include a shifting and maintenance component for the cases in which covert shifts of attention are made without the intention to execute a saccade.

This study uses meta-analytic methods to explore programmatic moderators or common factors of the effectiveness of marriage and relationship education (MRE) programs. We coded 148 evaluation reports for potential programmatic factors that were associated with stronger intervention effects, although the range of factors we could code was limited by the lack of details in the reports. Overall, we found a positive effect for program dosage: moderate-dosage programs (9-20 contact hours) were associated with stronger effects compared to low-dosage programs (1-8 contact hours). A programmatic emphasis on communication skills was associated with stronger effects on couple communication outcomes, but this difference did not reach statistical significance for the relationship quality/satisfaction outcome. There was no evidence that institutionalized MRE programs (formal manuals, ongoing presence, formal instructor training, multiple evaluations) were associated with stronger effects. Similarly, there was little evidence of differences in program setting (university/laboratory vs. religious). We discuss possible explanations for these findings and implications for program design and evaluation. 相似文献

ObjectiveThe purpose of the present study was to explore the role of the therapist in the dissemination of manualized cognitive behavior therapy (CBT) for chronic fatigue syndrome (CFS) outside specialized treatment settings.MethodWe used the routinely collected outcome data of three community-based mental health care centers (MHCs) which implemented and sustained CBT for CFS during the course of the study. Ten therapists, who all received the same training in CBT for CFS, and 103 patients with CFS were included.ResultsRandom effects modeling revealed a significant difference in mean post-treatment fatigue between therapists. The effect of the therapist accounted for 21% of the total variance in post-treatment fatigue in our sample. This effect could be explained by the therapists’ attitude toward working with evidence-based treatment manuals as well as by the MHC where CBT for CFS was delivered.ConclusionThe context in which CBT for CFS is delivered may play an important role in the accomplishment of established therapy effects outside specialized treatment settings. Due to the small sample size of MHCs and the different implementation scenarios in which they were engaged, our findings should be interpreted as preliminary results which are in need for replication. 相似文献

Three experiments were conducted to investigate the impact of stimulus-driven control on the time-course of stimulus-response (SR) compatibility. Participants responded to the presence or absence of a singleton arrow that was presented among multiple nontargets. When the singleton arrow was present, observers pressed a button with their right index finger, when it was absent they pressed with their left-index finger. SR-compatibility depended on the relation between the identity of the target and the present response: Even though the identity of the target singleton arrow (whether it was pointing to the right or left) was irrelevant to the task, the direction could be corresponding (right arrow) or noncorresponding (left arrow) with a target present response (the right hand). To examine the time-course of performance target-distractor similarity was varied to increase or decrease visual search efficiency and accordingly response latency. There were three main findings. First, the results of Experiment 1 showed that observers were no faster to respond 'present' when the singleton arrow pointed to the right (corresponding to the right hand) than when it pointed left (noncorresponding to the right hand) in a simple present-absent detection task. Second, only when observers were encouraged to process the identity of the arrow singleton, an effect of an SR-compatibility effect was found which developed over time. Third, the time-course of SR-compatibility was not influenced by visual search efficiency. The results of the present work suggest that visual selection and response selection occur in different stages. 相似文献

Abstract : In this article I argue that the Lutheran doctrine of two kingdoms provides a good basis for the legitimate participation of all citizens in political discourse and decisions, no matter what faith they hold. The argument is backed by selected insights from philosopher Jürgen Habermas and sociologists Linda Woodhead and Paul Heelas. Against this backdrop, I suggest some challenges for a theology that addresses issues related to religion and society. 相似文献
