The study investigated the influence of cognitive avoidance, positive affect, and gender on the evaluation of and memory for threat-related information varying in degrees of aversiveness and ambiguity. Stimulus material consisted of threatening, nonthreatening, and ambiguous pictures. First, valence ratings of the stimuli were collected. This phase was followed by a first memory test. A second memory test was administered three days later. Memory for aversive information was influenced by cognitive avoidance, positive affect, and gender. Avoiders exhibited a comparatively good memory for aversive information in the first (immediate) test and a very poor memory in the delayed testing. A similar pattern was obtained for individuals high in positive affect. Compared to men, women gave more negative ratings to aversive and ambiguous pictures and had a better memory for ambiguous information in the immediate test. Results are discussed within the framework of the repressive discontinuity hypothesis proposed by Hock and Krohne [Hock, M., Krohne, H. W. (2004). Coping with threat and memory for ambiguous information: Testing the repressive discontinuity hypothesis. Emotion, 4, 65–86]. 相似文献

Four motion quartets, each ambiguous with respect to the perception of parallel-path horizontal or vertical motion, were arranged in a diamond configuration. Both global parallel-path motion (the same motion axis for all the quartets), which is typical for multiquartet stimuli, and global rotational rocking are perceived. Experiment 1 indicated that rotational rocking is established at different levels of processing. Globally, larger displacements of each quartet's elements increase the angle of rotation and, thereby, the perception of rotational rocking. Locally, larger displacements have the opposite effect, weakening motion percepts. Experiment 2 showed that global-to-local feedback affects the local perception of rotation-consistent versus rotation-inconsistent motion directions. Experiment 3 provided evidence for hysteresis effects indicative of competition between global rotational rocking and parallel-path motion. The experimental results were simulated by a two-level dynamical model incorporating global-to-local feedback, with recurrent feedforward/feedback loops creating detection instabilities that amplify activation at both global and local levels of the rotational-rocking pattern. 相似文献

The aim of this article is to propose the formative measurement approach that can be used in various constructs of applied psychology. To illustrate this approach, the authors will (a) discuss the distinction between commonly used principal-factor (reflective) measures in comparison to the composite (formative) latent variable model, which is often applied in other disciplines such as marketing or engineering, and (b) point out the advantages and limitations of formative specifications using the example of the work-family balance (WFB) construct. Data collected from 2 large cross-sectional field studies confirm the reliability and validity of formative WFB measures as well as its predictive value regarding criteria of WFB (i.e., job satisfaction, family satisfaction, and life satisfaction). Last, the specific informational value of each formative indicator will be demonstrated and discussed in terms of practical implications for the assessment in different psychological fields. 相似文献

ABSTRACTThe differentiation of trait anxiety and depression in nonclinical and clinical populations is addressed. Following the tripartite model, it is assumed that anxiety and depression share a large portion of negative affectivity (NA), but differ with respect to bodily hyperarousal (specific to anxiety) and anhedonia (lack of positive affect; specific to depression). In contrast to the tripartite model, NA is subdivided into worry (characteristic for anxiety) and dysthymia (characteristic for depression), which leads to a four-variable model of anxiety and depression encompassing emotionality, worry, dysthymia, and anhedonia. Item-level confirmatory factor analyses and latent class cluster analysis based on a large nation-wide representative German sample (N?=?3150) substantiate the construct validity of the model. Further evidence concerning convergent and discriminant validity with respect to related constructs is obtained in two smaller nonclinical and clinical samples. Factors influencing the association between components of anxiety and depression are discussed. 相似文献

For decades sequential sampling models have successfully accounted for human and monkey decision-making, relying on the standard assumption that decision makers maintain a pre-set decision standard throughout the decision process. Based on the theoretical argument of reward rate maximization, some authors have recently suggested that decision makers become increasingly impatient as time passes and therefore lower their decision standard. Indeed, a number of studies show that computational models with an impatience component provide a good fit to human and monkey decision behavior. However, many of these studies lack quantitative model comparisons and systematic manipulations of rewards. Moreover, the often-cited evidence from single-cell recordings is not unequivocal and complimentary data from human subjects is largely missing. We conclude that, despite some enthusiastic calls for the abandonment of the standard model, the idea of an impatience component has yet to be fully established; we suggest a number of recently developed tools that will help bring the debate to a conclusive settlement. 相似文献

The who and whom of help giving: An attributional model integrating the help giver and the help recipient 下载免费PDF全文
In this article, we investigate the influence of responsibility, moral emotions, and empathy on help giving for stigmatized persons in need. Both characteristics of the recipient of help and the help giver are analyzed within a general theoretical framework. Based on an online study (N = 332), structural equation models confirm and extend an attributional explanation of help‐giving, based on a thinking‐feeling‐acting model. Conditions promoting help giving are identified: (i) A potential help giver who regards himself or herself as responsible for the recipient's misfortune is likely to experience guilt, regret, and shame, thus increasing the likelihood of help. (ii) A potential recipient of help who is regarded as being not responsible for his or her plight elicits sympathy and is thus more likely to receive help. In contrast, when the person in need is regarded as being responsible for his or her plight, anger and even schadenfreude are elicited, and likelihood of help giving decreases. (iii) Different aspects of empathy as a stable personal characteristic exert direct and indirect (i.e., emotionally mediated) effects on help giving. Using structural equation modeling, we outline an attributional model of helping conceptualizing helping behavior within an actor–observer system integrating a variety of moral emotions involved in help giving. 相似文献

Previous theory and research suggest that team reflection is beneficial for team performance. We argue that results remain inconclusive because prior studies have not accounted for the dynamic nature of this relationship. This paper addresses this research gap by examining time-specific relationships among variables and the intra-team variability of changes across time. In a four-wave longitudinal field study with 97 teams (N = 453 team members) performing a business simulation task, short-term (i.e., autoregressive, cross-lagged effects) and long-term (i.e., latent trajectories) relationships between team reflection and performance were explored. We found evidence that reflection had negative autoregressive effects and that there were direct positive short-term relationships between reflection and performance. Reflection trajectories were seen to decline across time and performance trajectories to increase across time. In addition, teams with either low initial reflection or low initial performance showed higher increases in reflection across time, whilst higher increase in reflection was negatively related to change in performance. Findings are discussed with respect to how they extend the previous literature and what directions they suggest for future research. 相似文献

A computational model for the perception of counterchange-specified motion is examined in detail and compared with various versions of the Reichardt motion detection model [Reichardt, W. (1961). Autocorrelation, a principle for the evaluation of sensory information by the central nervous system. In W. A. Rosenblith (Ed.), Sensory communication (pp. 303-317). New York: Wiley]. The counterchange model is composed of a pair of temporally biphasic subunits at two retinal locations, one detecting decreases and the other increases in input activation. Motion is signaled when both subunits are simultaneously excited, as determined by the multiplicative combination of their transient responses. In contrast with the Reichardt detector, which effectively tracks motion energy and accounts solely for results obtained with standard apparent motion stimuli (a surface is visible at one location, then at another), the counterchange model also accounts for the generalized apparent motion perceived between pairs of simultaneously visible surfaces. This indicates that standard apparent motion can be perceived via the same non-sequential, non-motion-energy mechanism as generalized apparent motion. There is no need for either an explicit delay mechanism to account for optimal motion perception at non-zero inter-stimulus intervals, or for inhibitory interaction between subunits to account for the absence of motion in the detector’s null direction (Barlow, H. B., & Levick, W. R., 1965). Both are emergent properties that result from the inhibitory states of the counterchange detector’s biphasic subunits. In addition to apparent motion, the counterchange principle potentially accounts for the perception of motion for drifting gratings, the short range motion perceived for random-dot cinematograms, and the motion perceived for continuously moving objects. 相似文献

Videotapes of territorial confilicts between rock wallabies, Petrogale assimilis, were analysed by means of sequential and frequency analysis. P. assimilis differes from most species of macropodoids in that they form long-lasting pair-bonds, and both partners of a pair defend a common territory within a colony. The video-analysis reveals differences between fights of P. assimilis and the “typical” pattern of macropod fighting. Most conflicts are solved by display. Even in actual fighting, few elements of “physical aggression,” such as biting or kicking, etc., are evident, and there is no winner/loser typical frequency difference of any elements. Many conflicts end as a draw. These differences are similar to differences between fighting in territory holders of small monoganous African can antelopes and those of other, more polygynous bovid. © 1994 Wiley-Liss, Inc. 相似文献
