The current study uniquely extended research that has linked traumatic event exposure to panic-spectrum problems among adolescents. It was hypothesized that among 127 adolescents (age range: 10 to 17 years; M = 14.63, SD = 2.24), those who endorsed a history of traumatic event exposure would evidence significantly greater anxious and fearful reactivity to a well-established 3-min voluntary hyperventilation procedure compared to nonexposed individuals. Results were consistent with hypotheses, suggesting traumatic event exposure is associated with anxious and fearful reactivity to abrupt increases in bodily arousal among adolescents. Moreover, consistent with hypotheses, anxiety sensitivity significantly mediated the relations between traumatic event exposure and both self-reported panic symptoms and panic symptoms elicited by the challenge. Future prospective research is now needed to better understand temporal relations between traumatic event exposure and indices of panic and related vulnerability. 相似文献

Adolescence is a key period in terms of the development of anxiety psychopathology. An emerging literature suggests that early pubertal maturation is associated with enhanced vulnerability for anxiety symptomatology, although few studies have examined this association with regard to social anxiety. Accordingly, the current study was designed to further elucidate the relation between pubertal timing and social anxiety, with a focus on clarifying the role of gender. Participants were 138 adolescents (ages 12-17 years) recruited from the general community. Level of social anxiety was examined as a function of gender and within-sample pubertal timing. As expected, early maturing girls evidenced significantly higher social anxiety, compared with on-time girls and early maturing boys, and no other differences were found as a function of gender or developmental timing. Findings and future directions are discussed in terms of forwarding developmentally sensitive models of social anxiety etiology and prevention. 相似文献

We used general-case training, instructions, rehearsal, and feedback to teach 3 advanced flute students to improve their sight-reading skills. Training resulted in systematic decreases in note errors, rhythm errors, repetitions, and hesitations for each participant. The procedures and outcomes were socially validated through subjective evaluation by the participants and music teachers not involved with the study. 相似文献

“The Cancer Bond”: Exploring the Formation of Cancer Risk Perception in Families with Lynch Syndrome

This study explores the social context of hereditary cancer risk perception in three families, an African-American family,
a Mexican-American family, and a Caucasian family, each with Lynch Syndrome documented by a mismatch repair gene mutation.
Communication network assessments measured family communication about cancer experiences and genetic testing information among
a total of 26 participants. Participant narratives were evaluated to gain insight into how family cancer experiences and genetic
testing information have shaped perceptions of cancer risk. Analysis of communication networks indicated that some families
discussed cancer experiences to a greater extent than genetic testing information, and vice-versa. Interviews elucidated that
sharing both types of health information led participants to conceptualize linkages among a strong family history of cancer,
genetic testing information, and cancer prevention strategies. Understanding how different types of family communication influence
the formation of perceived hereditary disease risk may enhance efforts to tailor genetic counseling services for families. 相似文献

Researchers have investigated animals' causal knowledge with a task requiring subjects to use a tool to bring a reward within reach whilst avoiding a trap. Previous studies have suggested limitations in the ability of several species to avoid traps in tubes or tables. However, certain features may have inflated task difficulty. We tested 20 chimpanzees (Pan troglodytes), 7 orangutans (Pongo pygmaeus), 5 bonobos (Pan paniscus), and 5 gorillas (Gorilla gorilla) in the trap-table--a task in which subjects have to pull one of two rakes prepositioned behind two rewards on a flat surface. One of the rewards is in front of a trap into which it will fall. We investigated the effect of trap type, tool type, the number of available tools, and reinforcement regime on performance. We replicated previous findings showing that apes failed to choose the correct rake above chance. However, when they could instead choose where to insert a single tool, around 80% of the apes solved the trap-table task in the first trial, revealing an important effect of task constraints on their performance. 相似文献

Patients with conduction aphasia have been characterized as having a short-term memory deficit that leads to relative difficulty on span and repetition tasks. It has also been observed that these same patients often get the gist of what is said to them, even if they are unable to repeat the information verbatim. To study this phenomenon experimentally, patients with conduction aphasia and left hemisphere-injured controls were tested on a repetition recognition task that required them to listen to a sentence and immediately point to one of three sentences that matched it. On some trials, the distractor sentences contained substituted words that were semantically-related to the target, and on other trials, the distractor sentences contained semantically-distinct words. Patients with conduction aphasia and controls performed well on the latter condition, when distractors were semantically-distinct. However, when the distractor sentences were semantically-related, the patients with conduction aphasia were impaired at identifying the target sentence, suggesting that these patients could not rely on the verbatim trace. To further understand these results, we also tested elderly controls on the same task, except that a delay was introduced between study and test. Like the patients with conduction aphasia, the elderly controls were worse at identifying target sentences when there were semantically-related distractors. Taken together, these results suggest that patients with conduction aphasia rely on non-phonologic cues, such as lexical-semantics, to support their short-term memory, just as normal participants must do in long-term memory tasks when the phonological trace is no longer present. 相似文献

Impulsive and callous traits are more strongly associated with delinquent behavior in higher risk neighborhoods among boys and girls 总被引:1,自引:0,他引:1
The purpose of the present study was to determine whether the effect of impulsive and callous personality traits on delinquent behavior varied across neighborhood context in a population-based, statewide sample of 85,000 Iowa schoolchildren ages 10-19. Two previous studies examining the association between impulsivity and delinquency across disadvantaged and affluent neighborhoods have yielded contrasting findings. Results of the present study suggested a robust moderating effect of neighborhood context on personality risk for delinquency. The relation between impulsivity and delinquency was greater in neighborhoods low in collective efficacy compared to neighborhoods high in collective efficacy. A similar interaction was found for callous personality traits, indicating the consistency of the moderating effect of neighborhood context on personality risk for delinquency. Gender differences were also examined, and results were replicated in a holdout sample. 相似文献

Research has shown that those individuals high in agreeableness recruit helpful thoughts in hostile contexts, presumably in the service of controlling aggressive behavior. The present experiment follows from such work, but importantly does so in a manner seeking to support causal conclusions. Participants were randomly assigned to an experimental training condition, in which hostile prime words were followed by helpful target words, or to a control condition that did not involve such pairings. Those assigned to the experimental condition subsequently exhibited lower levels of aggression in a laboratory task. Additional considerations and findings support the potential involvement of self-regulation processes. In general terms, the experiment reveals that a brief cognitive manipulation targeting processes thought to underlie aggression control was in fact causally effective in reducing subsequent levels of aggressive behavior. 相似文献

In this study, the comprehensive value research by Schwartz (e.g. 1992) was linked to Fiske's relational models theory (RMT, e.g. Fiske, 1991). A sample of 297 people answered the personal values questionnaire (PVQ), the modes of relationship questionnaire (MORQ) and the relationship profile scale (RPS) in a web‐based online survey. As hypothesized, the set of 10 values correlated in a systematic manner—according to the circular structure of personal value systems—with both trait‐like construal of and motivational investment in the relational models communal sharing (CS), authority ranking (AR) and market pricing (MP). Further research concerning a person–environment value congruency approach to predict well‐being is suggested combining the two research traditions. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

The decision whether to undergo genetic counseling for hereditary breast and ovarian cancer is complex. Knowledge about the psychosocial conditions of women who are awaiting counseling is sparse. We aimed to compare the psychosocial conditions of women awaiting genetic counseling with those of women in two reference groups. We included 567 women referred to genetic counseling for hereditary risk of breast or ovarian cancer (Genetic Group), 689 women referred to mammography (Mammography Group) and a random sample of 2,000 women from the general population (Population Group). One to 4 weeks before the first counseling session or mammography, data were collected by questionnaires. Both women affected with cancer and unaffected women in the Genetic Group appeared to have a somewhat higher prevalence of cancer-specific-distress than the corresponding reference groups. Further research on the effect of pre- counseling interventions appear warranted in addition with exploring a potential association between waiting time and cancer-specific distress. 相似文献
