This study examines the association between exposures to multiple forms of childhood abuse (emotional, physical, sexual) and adult suicidal behavior in a sample of low-income, African American women. We hypothesized a linear relation between childhood abuse and risk for making a suicide attempt, such that the more forms of childhood abuse to which a woman was exposed, the greater her risk would be to make a suicide attempt. Logistic regression analyses revealed that, compared to women who did not report any experiences of childhood abuse, women who experienced one, two, or three forms of abuse were 1.83, 2.29, or 7.75 times more likely to attempt suicide, respectively (all statistically significant). Furthermore, compared to women who reported one or two types of abuse, women who reported all three types of abuse were statistically more likely to attempt suicide. These findings have implications for clinicians working with African American women who report either childhood abuse or exhibit suicidal behavior. 相似文献

In two experiments, we investigated the hypothesis that a strengthening of position-item associations underlies the improvement seen in performance on an immediate serial recall task, for a list that is surreptitiously repeated every third trial. Having established a strong effect of repetition, performance was tested on transfer lists in which half the items held the same position as in the repeated list (S-items) and the remainder moved (D-items). In Experiment 1, S-items showed a small advantage in order errors over control and D-items. A second experiment tested whether a design feature in Experiment 1 underlay this advantage. When the experimental design was better controlled, no improvement was shown for either S- or D-items over controls. These data were shown to be inconsistent with the results of computer simulations of a positional model. An alternative model is outlined. 相似文献

To replicate and extend the finding that distraction facilitates between session anxiety reduction (), 27 spider phobics underwent three 10-min sessions of in vivo exposure followed by one 10-min exposure session at a 4-week follow-up, while having either stimulus-relevant focused conversation or stimulus-irrelevant distracting conversation with the experimenter. Physiological arousal and subjective anxiety were measured during exposure, and self-efficacy, perceived control and performance on a behavioural task were measured at pre-treatment, post session-3, and follow-up. Monitoring and blunting coping styles were also measured at pre-treatment to assess their impact on treatment outcome. Despite equal physiological activation between the groups, those who underwent distracted exposure showed greater reductions in subjective fear within and between sessions, and showed greater increases in self-efficacy ratings, internal perceived control and performance on a behavioural task. Coping style did not interact with the effect of distraction or focusing during exposure, however blunters had less subjective anxiety reduction overall, particularly when they underwent focused exposure. Results are discussed in terms of the emotional processing model and self-efficacy theory. 相似文献

We analyzed sucrose responsiveness and associative tactile learning in two genetic strains of honey bees under laboratory conditions. These strains differ in their foraging behavior. Bees of the "high" strain preferentially collect pollen. "Low"-strain bees mainly forage for nectar. Responsiveness to different sucrose concentrations and tactile learning were examined using the proboscis extension reflex. Acquisition, extinction of conditioned responses, and responses to an alternative tactile stimulus were tested. High-strain bees are more responsive to sucrose than low-strain bees. Regardless of genotype, pollen foragers are more responsive to sucrose than nectar foragers. In bees of both strains we find the same relationship between responsiveness to sucrose and acquisition. Bees responding to low sucrose concentrations show more often the conditioned response during acquisition than those responding only to higher sucrose concentrations. Extinction of conditioned responses depends on the response probability during acquisition. Discrimination between the two tactile stimuli is affected by genotype but not by responsiveness to sucrose. High-strain bees discriminate better than low-strain bees. Our experiments thus establish links between division of labor, responsiveness to sucrose, and associative learning in honey bees. 相似文献

Reverse production effect: children recognize novel words better when they are heard rather than produced 下载免费PDF全文

This research investigates the effect of production on 4.5‐ to 6‐year‐old children's recognition of newly learned words. In Experiment 1, children were taught four novel words in a produced or heard training condition during a brief training phase. In Experiment 2, children were taught eight novel words, and this time training condition was in a blocked design. Immediately after training, children were tested on their recognition of the trained novel words using a preferential looking paradigm. In both experiments, children recognized novel words that were produced and heard during training, but demonstrated better recognition for items that were heard. These findings are opposite to previous results reported in the literature with adults and children. Our results show that benefits of speech production for word learning are dependent on factors such as task complexity and the developmental stage of the learner. 相似文献

Ethnographic work indicates that food transfer has social significance, but food transfer has not previously been considered as a nonverbal communication channel. We categorize social food transfer along two dimensions: nature of the behaviour in the transfer (X shares food with or feeds Y), and the state of the food transferred (Y's food never contacted by X, or Y's food previously bitten/tasted/touched by X; we call the latter food consubstantiation (shared substance)). These two dimensions generate the four conditions investigated in this study: no sharing, sharing, sharing with consubstantiation, and feeding. The social significance of these types of situations was assessed in two ways. American college students indicated in a questionnaire both the extent to which they transfer food within different relationships, and what they took to be normative among American college students. Second, a different group of students participated in an Asch impression study in which they observed a videotape of two young adults of opposite sex eating at a restaurant, with the variable across subjects being the four conditions designated above. Viewers were asked to assess the relationship between the young adults, and to rate the degree of intimacy between the adults in terms of mutual feelings and acts of intimacy (e.g. sharing drinks, touching, having sexual relations). Results from both studies are congruent, and indicate that sharing implies a positive/friendly social relationship, and feeding implies a stronger, often romantic relationship. Consubstantiation superimposed on sharing modestly increased judgments of intimacy and closeness of relationship. © 1998 John Wiley & Sons, Ltd. 相似文献

The present study compared 50 Irish and 50 US graduate and undergraduate psychology and counselling students on the ways they rated counsellors, counselling, and group counselling on a semantic differential. Males were also contrasted to females on these concepts. A 2 2 2 2 2 MANOVA was used for the data analysis where the independent variables were country, class, and gender, and the dependent variables were the evaluative and potency scales of the semantic differential for counsellors, counselling, and group counselling. The Irish sample rated the potency of counselling significantly higher as did women. Counselling graduates evaluated group counselling and counsellors significantly higher than psychology undergraduates. 相似文献

This study investigates how syntactic and semantic load factors impact sentence comprehension and BOLD signal under moderate hypoglycemia. A dual session, whole brain fMRI study was conducted on 16 healthy participants using the glucose clamp technique. In one session, they experienced insulin-induced hypoglycemia (plasma glucose at ∼50 mg/dL); in the other, plasma glucose was maintained at euglycemic levels (∼100 mg/dL). During scans subjects were presented with sentences of contrasting syntactic (embedding vs. conjunction) and semantic (reversibility vs. irreversibility) load. Semantic factors dominated the overall load effects on both performance (p < 0.001) and BOLD response (p < 0.01, corrected). Differential BOLD signal was observed in frontal, temporal, temporo-parietal and medio-temporal regions. Hypoglycemia and syntactic factors significantly impacted performance (p = 0.002) and BOLD response (p < 0.01, corrected) in the reversible clause conditions, more extensively in reversible-embedded than in reversible-conjoined clauses. Hypoglycemia resulted in a robust decrease in performance on reversible clauses and exerted attenuating effects on BOLD unselectively across cortical circuits.The dominance of reversibility in all measures underscores the distinction between the syntactic and semantic contrasts. The syntactic is based in a quantitative difference in algorithms interpreting embedded and conjoined structures. We suggest that the semantic is based in a qualitative difference between algorithmic mapping of arguments in reversible clauses and heuristic linking in irreversible clauses. Because heuristics drastically reduce resource demand, the operations they support would resist the load-dependent cognitive consequences of hypoglycemia. 相似文献

This study investigated posttraumatic stress and depression reactions among survivors of the Istanbul November 2003 terrorist bombings that destroyed synagogues, an HSBC bank, and the British General Consulate. One hundred and forty-nine survivors completed a questionnaire measuring exposure, current posttraumatic stress, and depression responses 6 months after the blasts. This study showed that the prevalence rate of posttraumatic stress disorder (PTSD) among survivors was 35.6%?and the rate of depression was 23.5%. PTSD was strongly predicted by perceived life threat, whereas depression was strongly predicted by death of a close friend. Overall, female survivors were found to be more vulnerable to developing posttraumatic stress as well as depression after the terrorist bombings. 相似文献

Body satisfaction is important for the prevention of disordered eating and body image disturbances. Yet, little is known about body esteem and what influences it among younger children. The purpose of this study was to evaluate body esteem and the relationships between body esteem, weight, gender, and physical activity in elementary school children. A total of 214 third graders in a U.S. Midwestern state participated in this correlational study. The Body Mass Index-for-age, the Body Esteem Scale (BES), BE-Weight, BE-Appearance, and a Physical Activity Checklist were used to examine the relationships between the variables using bivariate correlations and analysis of variance. While children's body esteem did not differ by physical activity, important interactions were identified between weight status and gender in global body esteem and BE-Appearance. It is critical to examine attitudes about weight and appearance and the relationship between body esteem and self-esteem further among middle childhood-aged children. 相似文献
