Depression has been associated with task-relevant increased attention toward negative information, reduced attention toward positive information, or reduced inhibition of task-irrelevant negative information. This study employed behavioural and psychophysiological measures (event-related potentials; ERP) to examine whether groups with risk factors for depression (past depression, current dysphoria) would show attentional biases or inhibitory deficits related to viewing facial expressions. In oddball task blocks, young adult participants responded to an infrequently presented target emotion (e.g., sad) and inhibited responses to an infrequently presented distracter emotion (e.g., happy) in the context of frequently presented neutral stimuli. Previous depression was uniquely associated with greater P3 ERP amplitude following sad targets, reflecting a selective attention bias. Also, dysphoric individuals less effectively inhibited responses to sad distracters than non-dysphoric individuals according to behavioural data, but not psychophysiological data. Results suggest that depression risk may be most reliably characterised by increased attention toward others' depressive facial emotion.  相似文献

Information search during decision-making may be influenced both by selective attention and by the criterion used for ceasing to search. When the items searched are themselves emotive, the affective state of the decision-maker may bias these search processes. If an automatic selective attention bias operates, it may produce mood-congruent effects irrespective of context; e.g., negative affect may focus attention on negative items of information. An alternative possibility, suggested by the mood-as-input model, is that the influence of affect on search may depend on how decision-makers understand their emotions within a given context. The present study tested predictions derived from relevant theories of affective bias, using feedback as a means to generate a context of success or failure. Hundred and sixty participants were required to access positive and negative items of information in choosing between different routes for a search-and-rescue mission. Outcomes of choices were manipulated experimentally, so that in one condition participants received mostly positive feedback, and in a second condition participants received mostly negative feedback. Results showed that the feedback manipulation influenced affect, but there was considerable variation in affective state within each condition. Associations between affect and information search were moderated by feedback condition. For example, positive affect was associated with more frequent sampling of positive information in the negative feedback condition, but the association reversed when feedback was positive. Findings were consistent with the mood-as-input hypothesis, but not with an automatic selective attention bias. Context may influence how the decision-maker interprets their affective state.  相似文献

People's self-images are grounded in autobiographical memories and, in particular, in the phenomenological experience associated with remembering. The desire to increase or maintain the positivity of the self-image (i.e., the self-enhancement motive) might thus play an important role in shaping memory phenomenology. This study examined this hypothesis by asking participants to recall positive and negative events that involve self-evaluations (i.e., pride and shame) and positive and negative events that involve evaluations about others (i.e., admiration and contempt); various phenomenological characteristics (e.g., sensory details, feeling of re-experiencing) were assessed using rating scales. The results show a positivity bias (i.e., subjectively remembering positive events with more details than negative events) for events that involve self-evaluations but not for events that involve evaluations of others. In addition, this bias was stronger for people high in self-esteem. It is concluded that biases affecting the phenomenology of autobiographical memory are part of the arsenal of psychological mechanisms people use to maintain a positive self-image.  相似文献

People tend to respond with more positive than negative affect to mildly emotional stimuli (i.e., positivity offset) and respond more strongly to very negative than to matched positive stimuli (i.e., negativity bias). In the current study, the authors examine individual differences in the positivity offset and negativity bias and demonstrate that both are stable over time and generalize across different kinds of stimuli (e.g., pictures, sounds, words, games of chance). Furthermore, the positivity offset and negativity bias are not redundant with traditional personality measures and exhibit differential predictive validity, such that both types of measures predict behavior in meaningful ways. Implications for a comprehensive understanding of affect and emotion and their relationship to physical and mental health are discussed.  相似文献

A lengthened response time when a distractor becomes a target, called negative priming, is an undisputed phenomenon in selective attention, yet just what the underlying mechanism responsible for negative priming is has not been resolved. In this study, the proportion of attended repetition trials was manipulated in order to test the predictions of three theories that have been proposed for explaining spatial negative priming: distractor suppression (e.g., Tipper, 1985), episodic memory retrieval (e.g., Neill, Valdes, &; Terry, 1995), and novelty bias (e.g., Milliken, Tipper, Houghton, &; Lupiáñez, 2000). The results supported the proposal that a novelty bias, which is flexible and can be overridden, is the primary mechanism responsible for priming in spatial tasks. Memory retrieval obscured the novelty bias for target processing, was more selective in older adults, and did not affect distractor processing. Novelty bias and distractor suppression may share the same inhibitory attentional mechanism.  相似文献

We aimed to study burnout as a process that develops over time. On the basis of the Conservation of Resources theory ( Hobfoll, 2002 ), we tested whether burnout induces a loss cycle, depleting resources, and enhancing demands. In addition, we investigated whether intrinsic job motivation and externally regulated job motivation attenuated or aggravated this loss cycle. Using a sample of 352 employees who answered online questionnaires in 2005 and 2007, we found that baseline burnout predicted future burnout that results from an increase in job demands (e.g., work overload) and a decrease in job resources (e.g., social support, information). Furthermore, external regulation aggravated the positive relationship between baseline burnout and demand accumulation. Intrinsic motivation attenuated the positive relationship between baseline burnout and resource loss. We conclude that intrinsic motivation is an important factor enabling employees to break through the negative cycle of burnout.  相似文献

The study investigated biases for negative information in component processes of visual attention (initial shift vs. maintenance of gaze) in dysphoric and nondysphoric individuals. Eye movements were recorded while participants viewed a series of picture pairs depicting negative, positive, and neutral scenes (each pair presented for 3 s). Biases in initial orienting were assessed from the direction and latency of the initial shift in gaze, whereas biases in the maintenance of attention were assessed from the duration of gaze on the picture that was initially fixated. Results indicated that the dysphoric group showed a significantly greater bias to maintain gaze longer on negative pictures, relative to control pictures, compared with the nondysphoric group. There was no evidence of a dysphoria-related bias in initial shift of orienting to negative cues. Results are consistent with a depression-related bias that operates in the maintenance of attention on negative material.  相似文献

Children often extend names to novel artifacts on the basis of overall shape rather than core properties (e.g., function). This bias is claimed to reflect the fact that nonrandom structure is a reliable cue to an object having a specific designed function. In this article, we show that information about an object's design (i.e., about its creator's intentions) is neither necessary nor sufficient for children to override the shape bias. Children extend names on the basis of any information specifying the artifact's function (e.g., information about design, current use, or possible use), especially when this information is made salient when candidate objects for extension are introduced. Possible mechanisms via which children come to rely less on easily observable cues (e.g., shape) and more on core properties (e.g., function) are discussed.  相似文献

ABSTRACT

Anxious individuals report disproportionately negative expectations concerning the future, termed the negative expectancy bias. In contrast, ageing is associated with an inflated expectancy for positive future events. A recent study [Steinman, S. A., Smyth, F. L., Bucks, R. S., MacLeod, C., &; Teachman, B. A. (2013). Anxiety-linked expectancy bias across the adult lifespan. Cognition and Emotion, 27, 345–355. doi:10.1080/02699931.2012.711743] found using an interpretation bias task, a negative expectancy bias in young adults and positive expectancy bias in older adults with high trait anxiety. Extending this, the current study examined expectancy bias for positive, negative and ambiguously emotionally toned information in younger and older adults with clinical levels of depression and anxiety to community control groups, thus allowing examination of both disorder status and age on biases. Clinical participants reported a pervasive tendency to expect negative events relative to positive regardless of whether the current scenarios were positive, negative or ambiguous. Older adults showed greater expectancy for future positive scenarios when the initial scenario was negative or ambiguous. Age moderated the negative expectancy bias shown by clinical participants for ambiguous scenarios. Clinical disorders in older adults attenuated the positive expectancy bias that was otherwise strong in community participants. These findings provide further evidence for age differences in processing of emotionally toned information, with older adults showing a greater expectancy for positive future events.  相似文献

We report a study that examined the existence of a cognitive developmental paradox in the counterfactual evaluation of decision-making outcomes. According to this paradox adolescents and young adults could be able to apply counterfactual reasoning and, yet, their counterfactual evaluation of outcomes could be biased in a salient socio-emotional context. To this aim, we analyzed the impact of health and social feedback on the counterfactual evaluation of outcomes in a laboratory decision-making task involving short narratives with the presence of peers. Forty risky (e.g., taking or refusing a drug), forty neutral decisions (e.g., eating a hamburger or a hotdog), and emotions felt following positive or negative outcomes were examined in 256 early, mid- and late adolescents, and young adults, evenly distributed. Results showed that emotional ratings to negative outcomes (regret and disappointment) but not to positive outcomes (relief and elation) were attenuated when feedback was provided. Evidence of development of cognitive decision-making capacities did also exist, as the capacity to perform faster emotional ratings and to differentially allocate more resources to the elaboration of emotional ratings when no feedback information was available increased with age. Overall, we interpret these findings as challenging the traditional cognitive developmental assumption that development necessarily proceeds from lesser to greater capacities, reflecting the impact of socio-emotional processes that could bias the counterfactual evaluation of social decision-making outcomes.  相似文献

Attentional bias to negative information has been proposed to be a cognitive vulnerability factor for the development of depression. In 2 experiments, the authors examined mood-congruent attentional bias in dysphoria. In both experiments, dysphoric and nondysphoric participants performed an attentional task with negative, positive, and neutral word cues preceding a target. Targets appeared either at the same or at the opposite location of the cue. Overall, results indicate that dysphoric participants show maintained attention for negative words at longer stimulus presentations, which is probably caused by impaired attentional disengagement from negative words. Furthermore, nondysphoric participants maintain their attention more strongly to positive words. These results are discussed in relation to recent developments in the pathogenesis and treatment of depression.  相似文献

F. Attneave (1954) famously suggested that information along visual contours is concentrated in regions of high magnitude of curvature, rather than being distributed uniformly along the contour. Here the authors give a formal derivation of this claim, yielding an exact expression for information, in C. Shannon's (1948) sense, as a function of contour curvature. Moreover, they extend Attneave's claim to incorporate the role of sign of curvature, not just magnitude of curvature. In particular, the authors show that for closed contours, such as object boundaries, segments of negative curvature (i.e., concave segments) literally carry greater information than do corresponding regions of positive curvature (i.e., convex segments). The psychological validity of this informational analysis is supported by a host of empirical findings demonstrating the asymmetric way in which the visual system treats regions of positive and negative curvature.  相似文献

Studies of memory bias for threat-relevant information in individuals with social anxiety have produced mixed results. These discrepancies may be because investigators have studied different memory processes or have used different memory tasks. We employed a video clarity judgement task to investigate implicit (capacity-free, automatic, unconscious) memory and a recognition task to investigate explicit (effortful, strategic, conscious) memory for threat in socially anxious individuals and nonanxious controls. Implicit memory for "old" (i.e., seen before) videos was defined as rating "old" videos as more clear than "new" (i.e., never seen before) videos. We created brief video clips that involved an actor or actress approaching the camera and commenting on some aspect of the viewer's actions, physical appearance, or belongings. Twenty-four videos were positive (e.g., "I really like your shoes"), and 24 were negative (e.g., "That is a horrible haircut"). Results revealed that the video clarity test was an effective measure of implicit memory. Furthermore, socially anxious individuals showed a larger implicit memory index for negative videos than did nonanxious and dysphoric controls. No group differences emerged for implicit memory for positive videos. Similarly, groups did not differ in recognition of, or false alarms for, positive and negative videos. These results demonstrate the role of implicit memory in social anxiety implying that information about threat may be automatically primed in these individuals.  相似文献

Coinciding with widespread efforts to address obesity, weight bias internalization (a process of self-devaluation wherein individuals apply weight-biased stereotypes to themselves) has gained increased attention as a robust correlate of poor health outcomes. The present meta-analysis aimed to provide the largest quantitative synthesis of associations between weight bias internalization and health-related correlates. Studies that provided zero-order correlations for cross-sectional or prospective associations between weight bias internalization and physical, psychosocial, and behavioral health correlates were included in the meta-analysis. Meta-regression determined whether these associations differed based on demographic (sex/gender, race, age), anthropometric (body mass index), and study-level (publication status, sample type, study quality) moderators. Data for 149 (sub)samples were identified that included between 14 and 18,766 participants (M sample size = 534.96, SD = 1,914.43; M age = 34.73, SD = 12.61, range = 9.95–65.70). Results indicated that greater weight bias internalization was concurrently associated with worse psychosocial (e.g., negative and positive mental health, social functioning), physical (e.g., BMI, weight maintenance, health-related quality of life [HRQoL]), and behavioral health (e.g., disordered eating behaviors, healthy eating, physical activity) across most constructs, with effects ranging from small to very large in magnitude. Preliminary evidence also suggested that greater weight bias internalization was subsequently associated with less weight loss and increased negative mental health. Notable variations in the nature and magnitude of these associations were identified based on the health-related correlate and moderator under consideration. These findings indicate that weight bias internalization is linked to multiple adverse health-related outcomes and provide insight into priorities for future research, theory building, and interventions in this area.  相似文献

There is evidence of maladaptive attentional biases for lexical information (e.g., Atchley, Ilardi, & Enloe, 2003; Atchley, Stringer, Mathias, Ilardi, & Minatrea, 2007) and for pictographic stimuli (e.g., Gotlib, Krasnoperova, Yue, & Joormann, 2004) among patients with depression. The current research looks for depressotypic processing biases among depressed out-patients and non-clinical controls, using both verbal and pictorial stimuli. A d′ measure (sensitivity index) was used to examine each participant's perceptual sensitivity threshold. Never-depressed controls evidenced a detection bias for positive picture stimuli, while depressed participants had no such bias. With verbal stimuli, depressed individuals showed specific decrements in the detection of positive person-referent words (WINNER), but not with positive non-person-referent words (SUNSHINE) or with negative words. Never-depressed participants showed no such differences across word types. In the current study, depression is characterised both by an absence of the normal positivistic biases seen in individuals without mood disorders (consistent with McCabe & Gotlib, 1995), and by a specific reduction in sensitivity for person-referent positive information that might be inconsistent with depressotypic self-schemas.  相似文献

The Implicit Association Test (IAT) is designed to measure the strength of mental association between each of a pair of target categories (e.g., Black vs. White) and each of a pair of attributes (e.g., negative vs. positive). Recent work on the mere acceptance effect shows that, if one of the categories is the focus of attention, then an apparent preference for the focal category can emerge on the IAT, even when no such preference actually exists. It has been suggested that mere acceptance could influence responding on names-based racial IATs, perhaps leading to an exaggeration of anti-Black/pro-White bias. Whether such IATs can be influenced by a mere acceptance effect is unknown, though. By manipulating whether “Black” or “White” was the focal category on a names-based racial IAT, the present studies addressed this very issue. The results were consistent with the operation of mere acceptance effects, but not effects large enough to fully explain the appearance of bias on the IAT.  相似文献

Consumers often need to make very rapid choices among multiple brands (e.g., at a supermarket shelf) that differ both in their reward value (e.g., taste) and in their visual properties (e.g., color and brightness of the packaging). Since the visual properties of stimuli are known to influence visual attention, and attention is known to influence choices, this gives rise to a potential visual saliency bias in choices. We utilize experimental design from visual neuroscience in three real food choice experiments to measure the size of the visual saliency bias and how it changes with decision speed and cognitive load. Our results show that at rapid decision speeds visual saliency influences choices more than preferences do, that the bias increases with cognitive load, and that it is particularly strong when individuals do not have strong preferences among the options.  相似文献

Control by action representation and input selection (CARIS) is a modeling framework for task-switching experiments, which considers action-related effects as critical constraints. It assumes that control operates by choosing control parameter values, representing input selection and action representation. Competing CARIS models differ in whether (a) control parameters are determined by current instructions or represent a perseveration, (b) current instructions apply to the input selection and/or to action representation. According to the chosen model (a) task execution results in a default bias in favor of the executed task thus creating perseverative tendencies; (b) control counteracts these tendencies by applying a transient momentary bias whose locus (input selection or action representation) changes as a function of task preparation time; (c) this happens because the task-cue (e.g., SHAPE) initially attracts attention to the immediately available cue-information (e.g., target shape) and then attracts it to inferred or retrieved information (e.g., "circle" is related to the right key press).  相似文献
