It was long believed that central arrows needed to be spatially predictive to produce a shift in spatial attention. Recent evidence indicates, however, that central spatially nonpredictive directional cues, like arrows, will trigger reflexive shifts in attention. We asked what this recent discovery means for past studies that used predictive directional cues such as arrows. Our findings indicate that predictive arrows produce attention effects that greatly exceed the individual or summed effects of reflexive orienting to nonpredictive arrows and volitional orienting to predictive numbers. This suggests that the especially large effect produced by predictive arrows reflects an interaction between reflexive and volitional orienting. Given the broad application of the predictive arrow cueing paradigm in both past and current research, the present data shed new light on a wide range of investigations, from psychophysical studies of basic attention to behavioural and neuroimaging studies of cognition and social development. 相似文献

Taking control of reflexive social attention 总被引:8,自引:0,他引:8
Attention is shifted reflexively to where other people are looking. It has been argued by a number of investigators that this social attention effect reflects the obligatory bottom-up activation of domain-specific modules within the inferior temporal (IT) cortex that are specialized for processing face and gaze information. However, it is also the case that top-down factors may modulate the activation of IT cells. Here we examined behaviorally whether reflexive social orienting is purely automatic or sensitive to top-down modulation. Participants were shown an ambiguous stimulus that could be perceived either as representing EYES or a CAR. In we demonstrated between groups that an automatic shift of attention, equivalent to that triggered by a schematic FACE, occurred only when the stimulus was referred to as possessing EYES. In all participants received the EYES and CAR conditions. When the stimulus was first referred to as a CAR and then as EYES, an attentional shift was only present for the EYES condition. However, when the stimulus was first referred to as possessing EYES, and then later as a CAR, attentional shifts were observed for both conditions. These data indicate that the emergence of a reflexive social attention effect is influenced by top-down mechanisms but in an asymmetrical manner. Top-down processes appear to be effective for triggering IT involvement, that is, for perceiving a stimulus as a face, which produces the social attention effect. But top-down mechanisms are ineffective once IT involvement has been triggered. That is, once a stimulus has been seen as having eyes, it continues to be seen that way, and accordingly, the social attention effect persists. 相似文献

Recent behavioral data have shown that central nonpredictive gaze direction triggers reflexive shifts of attention toward the gazed-at location (e.g., Friesen & Kingstone, 1998). Friesen and Kingstone suggested that this reflexive orienting effect is unique to biologically relevant stimuli. Three experiments were conducted to test this proposal by comparing the attentional orienting produced by nonpredictive gaze cues (biologically relevant) with the attentional orienting produced by nonpredictive arrow cues (biologically irrelevant). Both types of cues produced reflexive orienting in adults (Experiment 1) and preschoolers (Experiment 2), suggesting that gaze cues are not special. However, Experiment 3 showed that nonpredictive arrows produced reflexive orienting in both hemispheres of a split-brain patient. This contrasts with Kingstone, Friesen, and Gazzaniga's (2000) finding that nonpredictive gaze cues produce reflexive orienting only in the face-processing hemisphere of split-brain patients. Therefore, although nonpredictive eyes and arrows may produce similar behavioral effects, they are not subserved by the same brain systems. Together, these data provide important insight into the nature of the representations of directional stimuli involved in reflexive attentional orienting. 相似文献

This article presents the research carried out on a sample of 303 elderly men and women. In the last year they reported experiencing violence in the family as follows: psychological abuse (24.1%), financial exploitation (6.4%), physical abuse (4.4%), and sexual abuse (2.1%). The abusers were most often husbands (30.15%), sons (16.64%), daughters (14.01%), and wives (9.21%). In the partner relationship, 44%?of the women and 35%?of the men had experienced at least some form of violence. The results showed that elderly men and women who were victims of family abuse had poorer psychological health than those without such experiences. Elderly who had experienced partner violence consumed alcohol more often than those who had experienced violence by other household members. 相似文献

Obesity contributes to various pregnancy complications and therefore, may compromise maternal quality of life. The study aim was to investigate the relationship between body mass index (BMI) and health-related quality of life (HRQoL) during pregnancy. Study involved every 6th woman who gave birth in the Clinic for Obstetrics and Gynecology Clinical Center of Serbia during the year 2010. Initial and end pregnancy BMIs were calculated for every woman. The parturients (604) completed the SF36 questionnaire (physical-PHC; mental-MHC; total quality of life-TQL), Beck’s Depression Inventory, Fatigue Severity Scale, Pregnancy Symptom Scale, Multidimensional Personal Support Scale, and Acceptance of Illness Scale. Before pregnancy most women had normal or decreased weight, while at the end of pregnancy the majority were overweight or obese (p?=?0.000). Initial and end pregnancy weights (p?<?0.05) and BMIs (p?<?0.05) were positively correlated with depression. Depression was significantly lower in overweight compared to mildly or morbidly obese women during pregnancy (p?<?0.05). Pregnancy weight change correlated negatively with PHC (p?=?0.029), and positively with fatigue (p?=?0.030), and symptoms (p?=?0.011). Of all BMI categories, morbidly obese women had the worst feeling of social support (p?<?0.05). Pregnancy symptoms were significantly less problematic in women with normal weight compared to overweight and obese women during pregnancy (p?<?0.05). Assessing the impact of all investigated parameters together, we established significant models for PHC (p?=?0.036), depression (p?=?0.030), and fatigue (p?=?0.038). Pregnant women should be advised to keep their gestational weight gain within the normal recommended range to have a good pregnancy outcome and HRQoL. 相似文献

During organizational restructuring and downsizing, employees often worry about being redundant, actually are redundant, and/or feel unsatisfied with their jobs. Employees, in turn, often react with poor loyalty to and high voluntary exit from the organization. The current study addresses this process from a careers' perspective, showing that career adaptability in the form of employees' career exploration and planning can account for at least some of these relationships. Redundancy fostered employees' career adaptive behaviors while job insecurity inhibited their career planning. Career planning, in turn, positively predicted employees' loyalty to the organization five months later while career exploration negatively predicted employees' loyalty, and positively predicted employees' exit reactions in the form of turnover intentions, job-search behaviors, and actual turnover. Implications and directions for future research are discussed. 相似文献

It has recently been shown that presenting additional visuospatial information alongside to-be-remembered numbers in a digit
span task enhances participants’ memory for those items. However, the mechanisms behind this visuospatial bootstrapping effect have remained unspecified. In this article, we report evidence that this effect involves an integration of information
from verbal and visuospatial temporary memory with long-term-memory (LTM) representations and that the existence of a relevant
LTM representation is necessary for bootstrapping to occur. 相似文献

Two laboratory experiments were conducted to assess the extent to which goal setting theory explains the effects of goals that are primed in the subconscious on task performance. The first experiment examined the effect on performance of three primes that connote the difficulty levels of a goal in the subconscious. Participants (n = 91) were randomly assigned to one of three conditions where they were primed with either a photograph of a person lifting 20 pounds (easy goal), 200 pounds (moderately difficult goal), or 400 pounds (difficult goal). Following a filler task, participants were asked to “press as hard as you can” on a digital weight scale. Participants who were primed with the difficult goal exerted more effort than those who were primed with the moderate or easy goal. The second experiment examined whether choice of goal difficulty level can be primed. Participants (n = 133) were randomly assigned to one of two conditions. Those primed with a difficult goal consciously chose to set a more difficult goal on a brainstorming task than those who were primed with an easier goal. Similarly, their performance was significantly higher. Conscientiousness moderated the subconscious goal–performance relationship while the self‐set conscious goal partially mediated the subconscious goal–performance relationship. 相似文献
