Negative conditional stimulus (CS) valence acquired during fear conditioning may enhance fear relapse and is difficult to remove as it extinguishes slowly and does not respond to the instruction that unconditional stimulus (US) presentations will cease. We examined whether instructions targeting CS valence would be more effective. In Experiment 1, an image of one person (CS+) was paired with an aversive US, while another (CS?) was presented alone. After acquisition, participants were given positive information about the CS+ poser and negative information about the CS? poser. Instructions reversed the pattern of differential CS valence present during acquisition and eliminated differential electrodermal responding. In Experiment 2, we compared positive and negative CS revaluation by providing positive/negative information about the CS+ and neutral information about CS?. After positive revaluation, differential valence was removed and differential electrodermal responding remained intact. After negative revaluation, differential valence was strengthened and differential electrodermal responding was eliminated. Unexpectedly, the instructions did not affect the reinstatement of differential electrodermal responding.  相似文献

Non-suicidal self-injury (NSSI) is commonly used by young adults to regulate emotional responses. Yet, experimental examination of how people who self-injure appraise and respond to emotional stimuli is limited. We examined appraisals of, and responses to, emotive images in young adults who did and did not self-injure, and assessed whether these were impacted by exposure to a stressor. Study 1 (N?=?51) examined whether participants differed in their appraisals of emotional images. Study 2 (N?=?78) assessed whether appraisals of images changed after exposure to the Trier Social Stress Test. Ratings of emotional valence and arousal were collected in both studies; skin conductance was measured as an indicator of physiological arousal in Study 2. In Study 1 participants reporting NSSI rated positively valenced images as less pleasant than participants not reporting NSSI. In Study 2, after acute stress, participants reporting NSSI displayed dampened physiological reactions to positive images whereas participants who did not self-injure displayed heightened physiological reactions to these and rated them as more pleasant. Individuals who self-injure seem less able to engage in strategic mood repair after exposure to stress compared to people who do not self-injure.  相似文献

Two experiments are presented, which explore the presence of a distinctiveness advantage when recognising unfamiliar voices. In Experiment 1, distinctive voices were recognised significantly better, and with greater confidence, in a sequential same/different matching task compared with typical voices. These effects were replicated and extended in Experiment 2, as distinctive voices were recognised better even under challenging listening conditions imposed by nonsense sentences and temporal reversal. Taken together, the results aligned well with similar results when processing faces, and provided a useful point of comparison between voice and face processing.  相似文献

Purpose

The purpose of this study is to provide a deeper understanding of uncivil meeting behaviors (UMBs) by exploring their frequency, potential predictors, and perceived impact on meeting outcomes. Five forms of UMBs were identified and examined. Key situational variables (meeting characteristics) and individual differences (Big Five factors and the Dark Triad of personality) were explored as potential predictors of UMBs.

Methodology

We collected data from two independent samples of meeting participants (N s  = 345, 170) via two online surveys. We used confirmatory factor analysis, correlations, hierarchical multiple regressions, and relative weight analyses to analyze the data.

Findings

The findings demonstrated that attendees’ perceptions of UMBs were linked to lower ratings of meeting satisfaction and effectiveness. In particular, the ratings were most affected by the observation of attendees who did not participate actively and who showed inappropriate interpersonal behavior. Results further suggest situational variables (meeting purpose and meeting norms) and individual differences (narcissism, psychopathy, and agreeableness) as potential predictors of UMBs.

Implications

By showing the consequences of UMBs on meeting outcomes and by providing insights into potential causes of engagement in UMBs, this study offers valuable input for running and leading work meetings.

Originality/Value

No previous study has empirically examined how different forms of UMBs affect meeting outcomes. Additionally, the paper introduces situational and personality variables that may act as potential predictors of UMBs.

The present study aimed to clarify the inconsistent relationship between negative affect and innovative work behaviour by taking into account the role of affect activation and mindfulness. Building on the conservation of resources theory, we hypothesized that low-activated negative affect can be associated with increased innovativeness, but only for employees with high levels of mindfulness. Conversely, high-activated negative affect is expected to have a positive, direct relationship with innovative work behaviour. Data were collected from two independent samples, namely 163 French Canadian and 101 Italian employees. Consistent with our predictions, multiple regression analysis results showed that low-activated negative affect was positively related to innovative behaviour only when mindfulness was high (vs. low), whereas high-activated negative affect was directly associated with higher innovativeness. Our findings challenge the assumption that low-activated negative affects are associated with undermined innovative behaviour, suggesting that these affective states can be related to increased innovativeness if employees are mindful. On the other hand, they support the view that high-activated negative affects provide the energizing potential for instigating innovative actions. This study is unique in examining mindfulness as a moderator that is capable of shaping the link between deactivating negative affect and employee innovativeness. As such, it answers recent calls for research on how mindfulness can contribute to workplace functioning. Moreover, this is the first study to take into account the role of activation level in the negative affect-innovative work behaviour relationship.  相似文献

Since Hooker, Finkelman and Schwartzman (Psychometrika 74(3): 419–442, 2009) it is known that person parameter estimates from multidimensional latent variable models can induce unfair classifications via paradoxical scoring effects. The open question as to whether there is a fair and at the same time multidimensional scoring scheme with adequate statistical properties is addressed in this paper. We develop a theorem on the existence of a fair, multidimensional classification scheme in the context of the classical linear factor analysis model and show how the computation of the scoring scheme can be embedded in the context of linear programming. The procedure is illustrated in the framework of scoring the Wechsler Adult Intelligence Scale (WAIS-IV).  相似文献

Prior research has shown that exposure to alcohol‐related images exacerbates expression of implicit racial biases, and that brief exposure to alcohol‐related words increases aggressive responses. However, the potential for alcohol cue exposure to elicit differential aggression against a Black (outgroup) relative to a White (ingroup) target—that is, racial discrimination—has never been investigated. Here, we found that White participants (N = 92) exposed to alcohol‐related words made harsher judgments of a Black experimenter who had frustrated them than participants who were exposed to nonalcohol words. These findings suggest that exposure to alcohol cues increases discriminatory behaviors toward Blacks.  相似文献

Previous behavioral and neurophysiological research has shown better memory for horizontal than for vertical locations. In these studies, participants navigated toward these locations. In the present study we investigated whether the orientation of the spatial plane per se was responsible for this difference. We thus had participants learn locations visually from a single perspective and retrieve them from multiple viewpoints. In three experiments, participants studied colored tags on a horizontally or vertically oriented board within a virtual room and recalled these locations with different layout orientations (Exp. 1) or from different room-based perspectives (Exps. 2 and 3). All experiments revealed evidence for equal recall performance in horizontal and vertical memory. In addition, the patterns for recall from different test orientations were rather similar. Consequently, our results suggest that memory is qualitatively similar for both vertical and horizontal two-dimensional locations, given that these locations are learned from a single viewpoint. Thus, prior differences in spatial memory may have originated from the structure of the space or the fact that participants navigated through it. Additionally, the strong performance advantages for perspective shifts (Exps. 2 and 3) relative to layout rotations (Exp. 1) suggest that configurational judgments are not only based on memory of the relations between target objects, but also encompass the relations between target objects and the surrounding room—for example, in the form of a memorized view.  相似文献

In the present study, the predictors and outcomes associated with the trajectories of peer rejection were examined in a longitudinal sample of Italian children (338 boys, 269 girls) ages 10 to 14 years. Follow-up assessments included 60% of the original sample at age 16–17. Low, medium, and high rejection trajectory groups were identified using growth mixture models. Consistent with previous studies, we found that (a) being less prosocial and more physically aggressive at age 10 was characteristic of those children with the high rejection trajectory; (b) being less attractive was related to higher peer rejection from age 10 to 14; and (c) boys with a high rejection trajectory showed high levels of delinquency and anxiety-depression and low levels of academic aspiration at age 16–17, whereas girls with a high rejection trajectory showed low levels of academic aspiration and social competence at age 16–17. Our findings indicate the detrimental consequences of peer rejection on children’s development and adjustment and shed light on the mechanisms that contribute to maintaining or worsening (e.g., being attractive, prosocial, and aggressive) a child’s negative status (e.g., being rejected) within his or her peer group over time.  相似文献
