Successful interactions between people are dependent on rapid recognition of social cues. We investigated whether head direction – a powerful social signal – is processed in the absence of conscious awareness. We used continuous flash interocular suppression to render stimuli invisible and compared the reaction time for face detection when faces were turned towards the viewer and turned slightly away. We found that faces turned towards the viewer break through suppression faster than faces that are turned away, regardless of eye direction. Our results suggest that detection of a face with attention directed at the viewer occurs even in the absence of awareness of that face. While previous work has demonstrated that stimuli that signal threat are processed without awareness, our data suggest that the social relevance of a face, defined more broadly, is evaluated in the absence of awareness.  相似文献

Alcohol consumption and cognitive impairment frequently co-occur. We propose that the relationship is so familiar that exposure to alcohol cues primes expectations of cognitive impairment. Across five studies, we find that in the absence of any evidence of reduced cognitive performance, people who hold an alcoholic beverage are perceived to be less intelligent than those who do not, a mistake we term the imbibing idiot bias. In fact, merely priming observers with alcohol cues causes them to judge targets who hold no beverage at all as less intelligent. The bias is not driven by a belief that less intelligent people are more likely to consume alcohol. We find that the bias may be costly in professional settings. Job candidates who ordered wine during an interview held over dinner were viewed as less intelligent and less hireable than candidates who ordered soda. However, prospective candidates believe that ordering wine rather than soda will help them appear more intelligent.  相似文献

Anxiety sensitivity (AS), the fear of anxiety-related symptoms, is strongly implicated in the development of anxiety disorders and is associated with other types of psychopathology. Little is known, though, about the processes through which AS might precipitate distress. As a preliminary step in understanding mechanisms, the mediational role of stress perception was evaluated in a nonclinical sample using a cross sectional design. We conducted a comparison between trait anxiety (TA) and AS to test whether any observed relations were specific to fear of anxiety (AS) or whether associations could be explained by the more general construct. Perceived stress mediated the relation between AS, and specific AS components, and panic symptoms and depression; but not in analyses where TA was statistically controlled. Perceived stress was not found to mediate the relation between TA and panic symptoms or depression, although TA, perceived stress and depression were highly correlated. Although incremental validity was not demonstrated in the present study, stress perception may be an important process through which AS amplifies reactivity to demanding life circumstances and further study is warranted.  相似文献

The interaction model of anxiety was examined by assessing both state and trait anxiety in 64 male military personnel on a Basic Parachutist Course. Two separate tests of the interactional model of anxiety were conducted, involving physical danger and social evaluation situations. The same subjects participated in both studies. In both physical danger and social evaluation studies, measures of state anxiety and cognitive appraisal (perception) of anxiety were obtained in both high-stress and non-stress conditions. Measures of social evaluation and physical danger trait anxiety were obtained in a low-stress condition. The interactional model was strongly supported for the physical danger situation. As predicted, high physical danger trait anxiety subjects experienced greater increases in state anxiety than low physical danger subjects proceeding from the non-stress to the high stress physical danger condition. The interaction model was not supported in the social evaluation situation; although not significant, mean levels of state anxiety were in the predicted direction. Results are discussed in the context of person perception and the need for testing personality models in realistic field settings.  相似文献

This study explored South African adolescents’ perceived risk and protection for HIV infection. Adolescents (N=28) with a mean age of 14.6 years receiving mental health care participated in Focus Group Discussions (FGDs) to engage in an in-depth exploration of their perceived risk and protective mechanisms for HIV prevention. The data were analysed using thematic content analysis. Themes that emerged from the FGDs associated with risk for HIV infection were: Alcohol and illicit drug use; Non-condom use; Prostitution and risky sexual activity with multiple partners; and Non-disclosure of HIV status. Themes that emerged as protective mechanisms included: HIV knowledge and appropriate HIV risk reducing behaviour; and Proactive parental attitudes and behaviour. These findings highlight the importance of ascertaining the perceptions of adolescents about risk and protection from HIV infection in order to inform future programs for HIV prevention among adolescents.  相似文献

A comparison of mental illness and narcotic use in rural and urban areas indicates a greater incidence in areas with high population density. A hypothesis explored is that prior experiences condition some to be sanguine and others melancholic. Whereas both are vulnerable to stress, the reactions to signals indicating punishment will vary according to the conditioned temperament. The great frequency of signals in high population density areas activates a general stress reaction. Relief can be obtained for the melancholic by withdrawal, whereas for the sanguine it is by the use of drugs.  相似文献

Ideally, psychological and phenomenological studies of visual experience should be mutually informative. In that spirit, this article outlines parts of Maurice Merleau‐Ponty's phenomenological view of visual experience as a kind of independently active opaque bodily synthesis, and uses those views to (a) help ground and extend Alva Noë's rejection of the “snapshot” theory of visual experience in favor of a more enactive view of visual content, (b) critique a failing of Noë's account, and (c) show how the assumptions underlying more internalist and Cartesian views of visual experience can illegitimately creep in even when they are being carefully criticized.  相似文献

Emerging evidence suggests that variants of specific genes may influence some youths to seek out or associate with antisocial peers. Using genotypic data (N = 1,816) from the National Longitudinal Study of Adolescent Health (J. R. Udry, 1998, 2003), the authors tested this possibility. They found that the 10R allele of the dopamine transporter (DAT1) gene was associated with self-reported delinquent peer affiliation for male adolescents from high-risk environments (β range = .13-.14) despite controlling for delinquent involvement, self-control, and drug and alcohol use. The authors discuss the importance of using a biosocial framework to examine issues related to adolescent development.  相似文献

When using precision grip to pick up objects, there are many possible pairs of grasp points that permit the thumb and index finger to exert opposed forces for secure grip. Previously, it was shown that individuals select grasp points so that the line between them (grasp axis) passes through or near the center of mass (CoM), thus minimizing the torque around the grasp axis during lifting. The accuracy of grasp axis selection depended on object spatial symmetry, indicating the importance of vision. The authors investigated how grasp point selection is influenced by haptic as well as visual information. Ten participants lifted cuboids whose CoM was located either symmetrically in the geometric center or asymmetrically toward one end. Results for the asymmetric cuboid revealed that grasp points migrated toward the asymmetric CoM from the geometric center. This was more pronounced in the presence of visual cues that reliably indicated the location of CoM. The results suggest that grasp point selection is influenced by a multimodal representation of CoM.  相似文献

The current study employed a mixed‐methods approach to examine perceptions towards and knowledge of counselling psychologists, including perceived differences between counselling and clinical psychologists. One hundred and fourteen adult members of the Victorian general public participated in the study and completed a 65‐item questionnaire, the Counselling Psychology Status Survey. As predicted, results from quantitative analysis showed that counselling psychologists were reported to be highly needed, valued, and respected by the current sample of Victorian residents. Respondents also reported a high level of confidence in counselling psychologists to treat various mental illnesses. Thematic analysis of qualitative textual data derived from written responses to an open‐ended question revealed that compared with clinical psychologists, counselling psychologists were understood to be less qualified, less skilled, and to work with less severe or complex client presentations. Taken together, results from this study suggest that although counselling psychology appears to occupy a positive public image, the importance of public promotion and awareness‐raising of the specialist profession of counselling psychology, and the continuing need for public education into the nature of psychological services and the qualifications, skills, and competencies of practitioners of psychological service provision, particularly compared with clinical psychology, cannot be underestimated.  相似文献
