Responding to calls to contextualize social psychological variables in history, the present research examines the relationship between collective relative deprivation and collective esteem using a historical perspective. We hypothesized that collective relative deprivation perceived to be experienced during an important low-point in a group's history serves to define the group's current collective identity, which is in turn associated with collective esteem. In Study 1, cultural narrative interviews were conducted with Francophone and Anglophone Quebecers in order to identify key historical chapters for these groups and to examine the extent to which historical low-points were identity-defining features of their narratives. In Study 2, using the information obtained from these narratives, collective relative deprivation was explored across group members' perceived histories and related to current in-group entitativity and collective esteem. The relationship between collective relative deprivation thought to be experienced by one's group during a historical low-point and collective esteem was positive for both Anglophone and Francophone Quebecers and was mediated by in-group entitativity. Collective relative deprivation perceived to be experienced during a historical low-point serves to define one's collective identity, which is in turn associated with greater collective esteem.  相似文献

Drosophila larvae combine a numerically simple brain, a correspondingly moderate behavioral complexity, and the availability of a rich toolbox for transgenic manipulation. This makes them attractive as a study case when trying to achieve a circuit-level understanding of behavior organization. From a series of behavioral experiments, we suggest a circuitry of chemosensory processing, odor-tastant memory trace formation, and the "decision" process to behaviorally express these memory traces--or not. The model incorporates statements about the neuronal organization of innate vs. conditioned chemosensory behavior, and the types of interaction between olfactory and gustatory pathways during the establishment as well as the behavioral expression of odor-tastant memory traces. It in particular suggests that innate olfactory behavior is responsive in nature, whereas conditioned olfactory behavior is captured better when seen as an action in pursuit of its outcome. It incorporates the available neuroanatomical and behavioral data and thus should be useful as scaffold for the ongoing investigations of the chemo-behavioral system in larval Drosophila.  相似文献

A considerable amount of clinical research interest has recently developed regarding emotion dysregulation and psychopathology. Many have suggested that distinct affective management deficits may characterize anxiety and mood pathology. Despite increased research attention, efforts to validate and sufficiently investigate the psychometric properties of many self-report measures of affect regulation have been lacking. The current study examined the response behavior of 1566 undergraduate participants who completed the Affective Control Scale (ACS). The ACS assesses fear of intense emotion, and it is frequently used in empirical research. The present investigation examined the structural qualities of the measure using exploratory and confirmatory factor analytic techniques. Findings suggest the original four rationally-derived subscales do not adequately fit the observed response patterns. Rather, results indicated that a five-factor solution that included a subscale measuring emotion mismanagement better represented response behavior. Additional normative data and bivariate correlations with other measures of emotion regulation and affect are presented.  相似文献

Past research indicates that faces can be more difficult to ignore than other types of stimuli. Given the important social and biological relevance of race and gender, the present study examined whether the processing of these facial characteristics is mandatory. Both unfamiliar and famous faces were assessed. Participants made speeded judgments about either the race (Experiment 1) or gender (Experiments 2–4) of a target name under varying levels of perceptual load, while ignoring a flanking distractor face that was either congruent or incongruent with the race/gender of the target name. In general, distractor–target congruency effects emerged when the perceptual load of the relevant task was low but not when the load was high, regardless of whether the distractor face was unfamiliar or famous. These findings suggest that face processing is not necessarily mandatory, and some aspects of faces can be ignored.  相似文献

We show that the actuality operator A is redundant in any propositional modal logic characterized by a class of Kripke models (respectively, neighborhood models). Specifically, we prove that for every formula ${\phi}$ in the propositional modal language with A, there is a formula ${\psi}$ not containing A such that ${\phi}$ and ${\psi}$ are materially equivalent at the actual world in every Kripke model (respectively, neighborhood model). Inspection of the proofs leads to corresponding proof-theoretic results concerning the eliminability of the actuality operator in the actuality extension of any normal propositional modal logic and of any “classical” modal logic. As an application, we provide an alternative proof of a result of Williamson’s to the effect that the compound operator A□ behaves, in any normal logic between T and S5, like the simple necessity operator □ in S5.  相似文献

The present study aimed to examine the relevance of age of onset to the psychopathology of social phobia using a large clinical sample of 210 patients with social phobia. The two most common periods of onset were during adolescence (ages 14–17) and early childhood (prior to age 10). Structural regression modeling was used to test predictions that early onset social phobia would be associated with greater severity of the disorder, stronger current symptoms of depression and anxiety, greater functional impairment, and more pronounced levels of emotional disorder vulnerabilities (e.g., neuroticism/behavioral inhibition, extraversion, perceptions of control). Logistic regression was used to evaluate relationships between age of onset and the presence of acute and chronic stress at the time of onset. Results showed that earlier age of social phobia onset was associated with stronger current psychopathology, functional impairment, and emotional disorder vulnerabilities, and that later age of onset predicted the presence of an acutely stressful event around the time of disorder emergence. These results are discussed in regard to their clinical implications and congruence with prominent etiological models of the emotional disorders.  相似文献

We assessed intermanual transfer of the proprioceptive realignment aftereffects of prism adaptation in right-handers by examining alternate target pointing with the two hands for 40 successive trials, 20 with each hand. Adaptation for the right hand was not different as a function of exposure sequence order or postexposure test order, in contrast with adaptation for the left hand. Adaptation was greater for the left hand when the right hand started the alternate pointing than when the sequence of target-pointing movements started with the left hand. Also, the largest left-hand adaptation appeared when that hand was tested first after exposure. Terminal error during exposure varied in cycles for the two hands, converging on zero when the right hand led, but no difference appeared between the two hands when the left hand led. These results suggest that transfer of proprioceptive realignment occurs from the right to the left hand during both exposure and postexposure testing. Such transfer reflects the process of maintaining spatial alignment between the two hands. Normally, the left hand appears to be calibrated with the right-hand spatial map, and when the two hands are misaligned, the left-hand spatial map is realigned with the right-hand spatial map.  相似文献

We conducted six experiments to examine how manipulating perception versus action affects perception–action recalibration in real and imagined blindfolded walking tasks. Participants first performed a distance estimation task (pretest) and then walked through an immersive virtual environment on a treadmill for 10 min. Participants then repeated the distance estimation task (posttest), the results of which were compared with their pretest performance. In Experiments 1a, 2a, and 3a, participants walked at a normal speed during recalibration, but the rate of visual motion was either twice as fast or half as fast as the participants' walking speed. In Experiments 1b, 2b, and 3b, the rate of visual motion was kept constant, but participants walked at either a faster or a slower speed. During pre- and posttest, we used either a blindfolded walking distance estimation task or an imagined walking distance estimation task. Additionally, participants performed the pretest and posttest distance estimation tasks in either the real environment or the virtual environment. With blindfolded walking as the distance estimation task for pre- and posttest, we found a recalibration effect when either the rate of visual motion or the walking speed was manipulated during the recalibration phase. With imagined walking as the distance estimation task, we found a recalibration effect when the rate of visual motion was manipulated, but not when the walking speed was manipulated in both the real environment and the virtual environment. Discussion focuses on how spatial-updating processes operate on perception and action and on representation and action.  相似文献

We present the main features of the European French-Speaking Normative Study for the Rorschach comprehensive system (CS) in adults. After reviewing previous attempts at establishing norms and diverse methodological considerations, we justify the choices made for the present project based on a clear definition of the sample, careful control of recruitment and quality of data collection procedures. Results of phase 1 (N =146) are presented and analyzed. Main variables from the CS are described and some key variables are compared to samples currently used as references (from the US). Differences are observable, although it is too early at this point to draw any conclusions that could influence interpretation. Such conclusions will be formulated when data collection is completed (final objective N =450).  相似文献
