Increased vigilance to threat-related stimuli is thought to be a core cognitive feature of anxiety. We sought to investigate the cognitive impact of experimentally induced anxiety, by means of a 7.5% CO(2) challenge, which acts as an unconditioned anxiogenic stimulus, on attentional bias for positive and negative facial cues of emotional expression in the dot-probe task. In two experiments we found robust physiological and subjective effects of the CO(2) inhalation consistent with the claim that the procedure reliably induces anxiety. Data from the dot-probe task demonstrated an attentional bias to emotional facial expressions compared with neutral faces regardless of valence (happy, angry, and fearful). These attentional effects, however, were entirely inconsistent in terms of their relationship with induced anxiety. We conclude that the previously reported poor reliability of this task is the most parsimonious explanation for our conflicting findings and that future research should develop a more reliable paradigm for measuring attentional bias in this field.  相似文献

Parent–child interaction paradigms are often used to observe dysfunctional family processes; however, the influence of such tasks on a participant’s level of activation remain unclear. The aim of this pilot project is to explore the stimulus value of interaction paradigms that have been commonly used in child anxiety research. Twenty-nine parent–child dyads with clinically anxious (n = 16) and non-anxious (n = 13) youths engaged in a series of tasks (threat and non-threat) used in previous studies of parenting and youth anxiety. Heart rate (HR) data, as an indicator of physiological activation, were collected across tasks, and participants rated the perceived representativeness of their interactions in the laboratory to their usual behavior at home. Significant HR changes were observed for both parent and child. Change in child HR from baseline to non-threat task was smaller than change in HR from baseline to threat tasks. Change in parent HR from baseline to ambiguous situations tasks was smaller than changes from baseline to other threat tasks. Differences in HR change between anxious and non-anxious children were explored. Participants rated laboratory interactions as similar to those experienced in the home. Results suggest that presumably emotionally-charged discussion tasks may produce increased activation compared to tasks that were designed to be more neutral. Implications for future research and limitations are discussed.  相似文献

The paper shows why and how an empirical study of fast-and-frugal heuristics can provide norms of good reasoning, and thus how (and how far) rationality can be naturalized. We explain the heuristics that humans often rely on in solving problems, for example, choosing investment strategies or apartments, placing bets in sports, or making library searches. We then show that heuristics can lead to judgments that are as accurate as or even more accurate than strategies that use more information and computation, including optimization methods. A standard way to defend the use of heuristics is by reference to accuracy-effort trade-offs. We take a different route, emphasizing ecological rationality (the relationship between cognitive heuristics and environment), and argue that in uncertain environments, more information and computation are not always better (the ??less-can-be-more?? doctrine). The resulting naturalism about rationality is thus normative because it not only describes what heuristics people use, but also in which specific environments one should rely on a heuristic in order to make better inferences. While we desist from claiming that the scope of ecological rationality is unlimited, we think it is of wide practical use.  相似文献

This study explored undergraduate students’ interpersonal responses, namely general feelings toward and desire for further social interaction with trans persons in a helping context. Secondarily, this study explored the relationship between participants’ intrinsic empathy, interpersonal curiosity and interest in further interaction. Two hundred fifty-one undergraduates at a moderate sized university in the southeastern United States served as participants. In order to assess baseline levels of empathy and curiosity, participants in session 1 completed the Interpersonal Reactivity Scale (Davis 1983) and the Interpersonal Curiosity Scale (Litman and Pezzo 2007). One week later, during session 2, the same students assumed the role of a peer counselor and read 1 of 4 (male, female, male-to-female, female-to-male) randomly assigned versions of an intake form completed by a fictitious peer client. Each version was identical, with the exception of the gender identity of the peer client. Participants completed various measures of affect and interest in further interaction. Male participants reported less willingness to interact with, and the strongest negative feelings toward the FTM peer client. Men reported highest willingness to interact with the MTF client and showed the lowest negative reactions towards the MTF client. Female participants’ scores on willingness to interact and on negative reactions were similar across all four intake form versions. Contrary to expectations, baseline levels of empathy and curiosity did not impact responses to gender expression. Further investigation is needed to elucidate the factors associated with anti-transgender prejudice particularly in the context of helping relationships.  相似文献

This mixed method study applies components of the theory of planned behavior (Ajzen and Fishbein 1980) to mother-adolescent conflict. We examine if three kinds of beliefs—behavioral, control, and normative—predict patterns of family conflict. Forty mother-adolescent dyads completed an open-ended interview, self-report measures of conflict, and an observational measure of family interaction. Hierarchical multiple regressions revealed that mothers’ and adolescents’ beliefs about the costs and benefits of conflict significantly predicted how they interacted and perceived conflict within dyads. Sex differences and differences between mothers and adolescents were identified. This work contributes to our understanding of the role of both general and specific beliefs in family conflict.  相似文献

There has been little research comparing the nature and contributions of language input of mothers and fathers to their young children. This study examined differences in mother and father talk to their 24 month-old children. This study also considered contributions of parent education, child care quality and mother and father language (output, vocabulary, complexity, questions, and pragmatics) to children's expressive language development at 36 months. It was found that fathers' language input was less than mothers' language input on the following: verbal output, turn length, different word roots, and wh-questions. Mothers and fathers did not differ on type-token ratio, mean length of utterance, or the proportion of questions. At age 36 months, parent level of education, the total quality of child care and paternal different words were significant predictors of child language. Mothers' language was not a significant predictor of child language.  相似文献

Parents’ verbal communication to their child, particularly the expression of fear-relevant information (e.g., attributions of threat to the environment), is considered to play a key role in children’s fears and anxiety. This review considers the extent to which parental verbal communication is associated with child anxiety by examining research that has employed objective observational methods. Using a systematic search strategy, we identified 15 studies that addressed this question. These studies provided some evidence that particular fear-relevant features of parental verbal communication are associated with child anxiety under certain conditions. However, the scope for drawing reliable, general conclusions was limited by extensive methodological variation between studies, particularly in terms of the features of parental verbal communication examined and the context in which communication took place, how child anxiety was measured, and inconsistent consideration of factors that may moderate the verbal communication–child anxiety relationship. We discuss ways in which future research can contribute to this developing evidence base and reduce further methodological inconsistency so as to inform interventions for children with anxiety problems.  相似文献

This article provides an account of a 10-year collaborative documentation of community leadership in an African American community on the South side of Chicago. The stories are oriented to several critical incidents in the life course of the collaboration. They are told from the perspectives of one university professor, four graduate students, and one community leader. Together they provide an account of how this research was shaped by the interactions of the research team with members of the community, how research questions emerged, methodologies were developed, ways of gathering data were tried and tested, and interpretations of data unfolded. Special attention is given to the ways in which the process and products of this research contributed to the community's own process of leadership development. The stories also discuss the various roles participants in this collaboration played both in the academic arena and in the community, and how they experienced gender, race, nationality, and social status.  相似文献

Blood-Injection-Injury (BII) phobia is associated with distress and avoidance in response to blood, injury, or receiving injections. BII phobia can therefore create problems for those receiving medical procedures such as chemotherapy. The prevalence rate of BII in the general population has been estimated to be less than 5% but as many as 19% of outpatients receiving chemotherapy surveyed by Carey and Harris (Behaviour Change 22:5–90, 2005) reported BII concerns. This study examined the extent and characteristics of BII concerns among outpatients receiving chemotherapy for the first time (n = 124). Almost 17% of the sample had scores on the Mutilation Questionnaire comparable to samples with clinical BII phobia. Those assigned to a high BII concern group based on Mutilation Questionnaire scores reported higher somatic and fainting responses to BII stimuli and elevated disgust sensitivity, compared to groups selected for low BII concerns. Females had significantly higher Mutilation Questionnaire scores than males. Thus, the BII concerns of outpatients receiving chemotherapy appear qualitatively similar to the concerns reported by clinical BII phobia samples and analogue student samples. We suggest that the standard inclusion of a brief, reliable screening measure of BII concerns for outpatients scheduled for chemotherapy, coupled with brief, effective interventions to reduce BII-related distress, may be warranted.  相似文献

This study examined the comprehension by children of the concepts of order, duration, and simultaneity as reflected in certain linguistic structures. The children in the study were 3, 5, and 7 years old. Temporal order was examined through children's comprehension of two-clause sentences containing the conjunctions after, before, since, and until. Temporal duration was examined through children's understanding of one-clause sentences containing the progressive aspect and two-clause sentences containing the conjunctions since and until. These two conjunctions signal duration in the main clause when they conjoin two clauses. Simultaneity was studied through children's comprehension of two-clause sentences containing while. The results revealed that the order sentence structures (before and after) were generally comprehended by the children before the duration or simultaneous sentence structures, although at 7 years of age children were still not performing above chance on the order relation in since and until sentences. The duration sentence structures were comprehended by the children before the simultaneous sentence structures. The results support the literature in cognitive psychology and in philosophy which argues that order is simpler than duration is simpler than simultaneity.This report is based on a dissertation submitted to the University of Michigan in partial fulfillment of the requirement for the Ph.D.  相似文献
