Although theory suggests that a bias for attending to threat information (ABT) may be a biobehavioral process underlying the transdiagnostic vulnerability factor of emotion dysregulation, there is a paucity of empirical evidence showing direct associations between emotion dysregulation and ABT. The purpose of the present study was to examine the relation between ABT and emotion dysregulation. Participants (N?=?200) completed a battery of self-report questionnaires and a modified dot-probe task with both neutral and threat stimuli and four stimulus presentation durations. Task response times were used to examine traditionally calculated ABT scores, as well as attention bias variability (ABV). As predicted, those with greater emotion dysregulation exhibited greater ABV. Importantly, emotion dysregulation was not associated with response time variability on trials for which only neutral stimuli were presented, thus increasing confidence that emotion dysregulation-related ABV is specific to the presence of threat stimuli and not merely a function of general variability in response times. Results suggest that those with greater emotion dysregulation exhibit attentional dyscontrol in the presence of perceived threat that is characterized by dynamic shifts between vigilance and avoidance.  相似文献

It has been suggested that the broad trait of neuroticism may predict the tendency to become aggressive when provoked. Based on functionalist theories of emotion, however, we suspected that only the more specific trait of anger would predict such tendencies. To test these competing predictions, two laboratory studies and one daily diary study were conducted. Consistent with functionalist accounts, trait anger consistently predicted the angry emotional and aggressive behavioral response to provocation, even after controlling for neuroticism. This was true in relation to laboratory-based provocations and in provocations experienced in daily life. Neuroticism only predicted a more diverse negative emotional reaction. It is therefore proposed that trait anger clearly elicits an angry emotional response, which directly motivates aggressive behavior. By contrast, neuroticism may lead to a very diverse reaction which elicits different and even contradictory behavioral tendencies.  相似文献

Behavioural characterisation of transgenic mice has been instrumental in search of therapeutic targets for the modulation of cognitive function. However, little effort has been devoted to phenotypic characterisation across environmental conditions and genomic differences such as sex and strain, which is essential to translational research. The present study is an effort in this direction. It scrutinised the stability and robustness of the phenotype of enhanced Pavlovian conditioning reported in mice with forebrain neuronal deletion of glycine transporter 1 by evaluating the possible presence of sex and circadian dependency, and its consistency across aversive and appetitive conditioning paradigms. The Pavlovian phenotype was essentially unaffected by the time of testing between the two circadian phases, but it was modified by sex in both conditioning paradigms. We observed that the effect size of the phenotype was strongest in female mice tested during the dark phase in the aversive paradigm. Critically, the presence of the phenotype in female mutants was accompanied by an increase in resistance to extinction. Similarly, enhanced conditioned responding once again emerged solely in female mutants in the appetitive conditioning experiment, which was again associated with an increased resistance to extinction across days, but male mutants exhibited an opposite trend towards facilitation of extinction. The present study has thus added hitherto unknown qualifications and specifications of a previously reported memory enhancing phenotype in this mouse line by identifying the determinants of the magnitude and direction of the expressed phenotype. This in-depth comparative approach is of value to the interpretation of behavioural findings in general.  相似文献

Creativity research has suggested that creative people are low in agreeableness. To explore this issue, we applied the HEXACO model of personality structure, which offers an expanded representation of interpersonal traits, particularly a distinction between Honesty-Humility and Agreeableness. A sample of 1304 adults completed the HEXACO-60 and several measures of creative achievement and activities. Latent variable models found that Agreeableness had no relationship with creativity, but Honesty-Humility did: people lower in Honesty-Humility had higher creativity scores, consistent with past work on arrogance and pretentiousness among creative people.  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
