Visual perception is an important component of environmental navigation. Previous research has revealed large individual differences in navigational strategies (i.e., the body’s kinesthetic and embodied approach to movement) and the perception of environmental surfaces (via distance estimations), but little research has investigated the potential relationship between these sources of individual variation. An important navigational strategy is the interaction between reliance on visual cues and vestibular or proprioceptive cues. We investigated the role of this navigational strategy in the perception of environmental surfaces. The results supported three embodied evolutionary predictions: Individuals who were most reliant on visual context (1) overestimated vertical surfaces significantly more, and (2) feared falling significantly more, than did those who were least reliant on visual context; and (3) all individuals had roughly accurate horizontal distance estimates, regardless of their navigational strategy. These are among the first data to suggest that individual differences in perception are closely related to the individual differences in navigation that derive from navigational risks. Variable navigational strategies may reflect variable capacities to perceive and navigate the environment.  相似文献

During the last five decades, a number of studies have attempted to draw from psychoanalytic theory to examine the relationship between evacuation disorders and a person's character. According to Freud's original conceptualization, early or harsh toilet training leads children to develop an anal retentive personality, characterized by the tendency to control their bowels as well as their material possessions; by contrast, liberal toilet training leads children to develop an anal expulsive personality, characterized by the tendency to excessively relieve faeces, as well as be being careless, messy, and inclined to dispose of old products and buy new ones. Although toilet training may not be responsible, these sets of traits do cohere. To empirically examine these hypotheses, we studied the personality traits and consumption habits of people suffering from different bowel disorders. By means of semistructured interviews, we analysed the personality characteristics, sociodemographic backgrounds, and peculiar consumption habits of people suffering from constipation and diarrhoeic syndromes. The results show that constipated people tend to be obstinate, excessively concerned with hygiene, and inclined toward retaining possessions, whereas diarrhoeic people tend to be careless, disorganized, and disposed to share their possessions with others. We discuss the theoretical and practical implications of these results and indicate avenues for future research.  相似文献

Safety behavior is involved in the maintenance of anxiety disorders, presumably because it prevents the violation of negative expectancies. Recent research showed that safety behavior is resistant to fear extinction. This fear conditioning study investigated whether safety behavior after fear extinction triggers a return of fear in healthy participants. Participants learned that two stimuli (A and C) were followed by an aversive loud noise (“threat”), and one stimulus (B) was not. Participants then learned to use safety behavior that prevented the loud noise. Next, A and C were no longer followed by the loud noise, which typically led to extinction of threat expectancy. Safety behavior then became available again for C, but not for A and B. All participants used safety behavior on these C trials. In a final test phase, A, B, and C were presented once without the availability to use safety behavior. At each stimulus presentation, participants rated threat expectancy by indicating to what extent they expected that the loud noise would follow. Compared with the last extinction trial, threat expectancy increased for C in the test phase, whereas it did not increase for A and B. Hence, safety behavior after the extinction of classically conditioned fear caused a partial return of fear. The findings suggest that safety behavior may be involved in relapse after exposure-based therapy for anxiety disorders.  相似文献

Anxiety and depressive disorders are among the most commonly diagnosed psychiatric disorders, yet they remain largely undertreated in the U.S. and Black adults are especially unlikely to seek or receive mental health services. Symptom severity has been found to impact treatment-seeking behaviors as have sociocultural factors. Yet no known research has tested whether these factors work synergistically to effect willingness to seek treatment. Further, emerging data point to the importance of transdiagnostic risk factors such as intolerance of uncertainty (IU). IU may be negatively related to seeking treatment given that Black adults may be uncertain whether treatment might benefit them. Thus, the current study examined the relations between symptom severity/IU and willingness to seek treatment for anxiety/depression problems and the impact of key sociocultural variables (i.e., cultural mistrust–interpersonal relations [CMI-IR], perceived discrimination [PED]) on these relations among 161 (85% female) Black undergraduates. Consistent with prediction, symptom severity was positively related to willingness, but unexpectedly, IU was positively related. There was a significant Symptom Severity × CMI-IR interaction such that severity was positively related to willingness among students with lower cultural mistrust, but not higher mistrust. There were also significant IU × PED interaction such that IU was positively related to willingness among students with lower PED, but not higher PED. Results highlight the importance of considering the interplay between symptom severity, transdiagnostic vulnerability factors, and sociocultural variables when striving to identify factors related to treatment seeking behaviors among anxious and/or depressed Black students.  相似文献

That facial expressions are universal emotion signals has been supported by observers agreeing on the emotion mimed by actors. We show that actors can mime a diverse range of states: emotions, cognitions, physical states, and actions. English, Hindi, and Malayalam speakers (N?=?1200) viewed 25 video clips and indicated the state conveyed. Within each language, at least 23 of the 25 clips were recognised above chance and base rate. Facial expressions of emotions are not special in their recognisability, and it is miming that may be the universal human ability.  相似文献

ABSTRACT

African migration to Canada is a relatively new development. There is a dearth of literature on the mental health of this newer immigrant population, especially those from the conflict zones of Sub-Saharan Africa. Our exploratory study examined the experiences of African female survivors of conflict-related sexualized violence based on the insights of six community mental health professionals. Guided by interpretive inquiry, semi-structured interviews were analyzed thematically and interpreted in light of multicultural feminist and transnational perspectives. Findings highlight refugee women’s resilience in the face of threats of social isolation and stigma. Their prioritization of assistance with practical needs, parenting, community/social supports, and education attainment in the context of counseling raises questions about agency and identity in understanding the relationships between female survivors, what they identify as important to their recovery, and their pathways to accessing mental health services.  相似文献

Many perceived cues to deception have been reported in the literature, but little attention has been paid to how they are combined when making deception judgments. The present research used a data‐driven approach to investigate how cues are integrated when evaluating veracity. Two hundred fifteen participants performed a deception detection task before completing a deception cue use questionnaire. A factor analysis of the questionnaire data produced two dimensions, one associated with nonverbal cues to anxiety and the other associated with detail and level of involvement. The present work extends our understanding of deception detection processes and underlines the importance of examining not only the cues that people use but also the way in which they use them.  相似文献

The SPoARC effect (Spatial Positional Associated Response Codes) has only been observed in working memory (WM) using closed sets. It is interpreted as showing that individuals spatialise to-be-remembered items in a left-to-right fashion, using spatialisation as context. Given that context is crucial for episodic memory (EM), we tested if this effect could be observed in EM by using 15-word lists taken from an open set. After each list, 30 probes were sequentially displayed to test recognition. The left/right-hand key assignment for yes/no answers was varied. No SPoARC effect was observed. However, as all previous SPoARC experiments had used short lists and closed sets, it was not possible to know if this absence of SPoARC was due to the open set feature or the length of the lists. A second experiment was thus run using open sets and short 5-word lists, which do not necessitate EM to be remembered. A SPoARC effect was observed indicating that Experiment 1 result was due to the involvement of supra-span lists and that SPoARC effects do not extend to EM with open sets. Experiment 2 also enabled us to generalise the SPoARC effect to open sets in WM for the first time.  相似文献

Anthropological studies in India inspired the idea of a distinct domain of moral purity, but a precise characterization of that domain has been elusive. One proposal based on current theorizing in psychology is that prototypical purity violations are self-harming actions, which are perceived as disgusting and immoral whether done accidentally or intentionally. In three studies (Ns?=?400, 80, 132), we examined judgments of self-harming actions in two cultural groups—American and Indian. There was little support for the proposed characterization of the purity domain: Self-harms were slightly to modestly immoral for Indians and Americans. Both Indians and Americans found self-harms to be sad, not disgusting. And intentionality influenced how immoral and how sad the action was judged. Instead, the findings supported a view that all immorality, including those concerning self-harm, depends on perceived harm.  相似文献
