ABSTRACT— Conditioning studies on humans and other primates show that fear responses acquired toward danger-relevant stimuli, such as snakes, resist extinction, whereas responses toward danger-irrelevant stimuli, such as birds, are more readily extinguished. Similar evolved biases may extend to human groups, as recent research demonstrates that a conditioned fear response to faces of persons of a social out-group resists extinction, whereas fear toward a social in-group is more readily extinguished. Here, we provide an important extension to previous work by demonstrating that this fear-extinction bias occurs solely when the exemplars are male. These results underscore the importance of considering how gender of the target stimulus affects psychological and physiological responses to out-group threat.  相似文献

How the perceptions of novel figurative phrases change over the course of numerous presentations were addressed in three studies using rating tasks (Studies 1 and 3) and recall tasks (Study 2). The present set of studies replicated much of Schweigert et al.’s (J Psychol Res 32:455–475, 2003) findings of changes in correlations among figurative phrases ratings. The results also suggest that catchiness, frequency heard agreement, and frequency used agreement can be used as predictors of phrase memorability and potential predictors of later idiomaticity.  相似文献

Echoics are a critical target of language intervention for children with autism, because a well‐established echoic repertoire on the part of the child allows the clinician to use vocal modeling as a flexible, low‐effort prompting procedure during teaching. In this study, we implemented a chaining procedure to increase the complexity of echoics in 2 children with autism and 1 child with developmental delay. The procedure was effective for all 3 participants, and gains were maintained after treatment was withdrawn in most cases.  相似文献

We examined the effects of three different presession conditions on tangibly maintained problem behavior for 2 students with autism, using individual-participant multielement designs. First, an analogue functional analysis demonstrated that problem behavior was maintained by access to tangible items. Next, topographies of item rejection were identified. Finally, students were exposed to (a) brief access, (b) no access, and (c) satiation to the tangible items prior to tangible sessions. The results demonstrated high levels of problem behavior following the brief-access and no-access presession conditions and low levels of problem behavior following the satiation condition. The findings are discussed in the context of how satiation might best be defined for these sorts of evaluations.  相似文献

Is the process of helping infants and young children learn to sleep through the night a solution to family sleep problems or does it exacerbate matters for mother and child? Retrospective and current accounts from a nonclinical, convenience sample of 102 mothers of preschool‐aged children provided information on sleep issues from early infancy through preschool age. Child, mother, and parenting characteristics, along with family sleep arrangements, were differentially related to the age at which children learned to sleep through the night and to the extent of difficulty that characterized this experience. Mothers who indicated more difficulty as their children learned to sleep through the night also reported more depressive symptoms and more strain in the mother–child relationship. Later age at sleeping through the night was more common among early bedsharers, but timing of sleeping through the night was not associated with preschool children's reported independence in several nonsleep domains. Sleep arrangements and the importance placed on sleeping through the night were the strongest contributors to variance explained in whether children learned to sleep through the night during infancy or toddlerhood. When advising parents about sleep interventions, practitioners should seek to understand whether families' parenting values fit their nighttime sleep practices.  相似文献

This study investigated the roles of the affect heuristic and outcome beliefs in explaining the relationship between negative urgency and adolescent binge drinking behaviour. The sample consisted of 391 Australian high school students, who were selected to be low or high on urgency. We hypothesised that highly urgent adolescents would be more likely than adolescents low in urgency to utilise the affect heuristic (i.e., to rely upon affective input) when making alcohol-related decisions. Multiple-group path analysis supported this prediction. Adolescents high in urgency exhibited greater use of the affect heuristic by displaying a direct path from affective associations to binge drinking; whereas adolescents low in urgency exhibited greater reliance upon rational processing by displaying an indirect path via outcome beliefs.  相似文献

The study examined whether face‐specific perceptual brain mechanisms in 9‐month‐old infants are differentially sensitive to changes in individual facial features (eyes versus mouth) and whether sensitivity to such changes is related to infants' social and communicative skills. Infants viewed photographs of a smiling unfamiliar female face. On 30% of the trials, either the eyes or the mouth of that face were replaced by corresponding parts from a different female. Visual event‐related potentials were recorded to examine face‐sensitive brain responses. Results revealed that increased competence in expressive communication and interpersonal relationships was associated with a more mature response to faces, as reflected in a larger occipito‐temporal N290 with shorter latency. Both eye‐ and mouth changes were detected, though infants derived different information from these features. Eye changes had a greater impact on the face perception mechanisms and were not correlated with social or communication development, whereas mouth changes had a minimal impact on face processing but were associated with levels of language and communication understanding.

To investigate neighbor effects in visual word recognition, the masked priming technique holds considerable advantages over unprimed methods, because a target word is used as its own control. However, inhibitory neighbor effects obtained with masked priming are still open for different interpretations, because the primes differ across conditions. Given this theoretical problem, it is useful to investigate neighbor priming effects using a prime as its own control. This option is available in the incremental priming technique (Jacobs, Grainger, & Ferrand, 1995), in which a within-condition baseline is created by comparing the response times (RTs) to a target when it is primed at different prime durations. In this study, we examined masked neighbor priming using this technique. Both the traditional and the within-condition baseline indicated that masked neighbor word priming is inhibitory in nature. The results are discussed in terms of current theories of visual word recognition.  相似文献

This is a report of the preliminary findings of a brief exploratory ethnographic study in a cancer diagnosis and treatment clinic. The main research purpose was to explore the meaning of cancer and cancer treatment to patients themselves and to their relatives and close friends. The methods are described in detail in a paper focusing on the experiences of being a novice ethnographer (Peters et al. (2001) J Genet Counsel 10(2):133–150.). The preliminary results of this exploratory fieldwork indicate that the experience of attending a cancer treatment clinic for evaluation and/or treatment is a complex social, emotional as well as medical process for patients and families. Themes with relevance to genetic counselors that emerged from this early observation period included ideas about causes of cancer, the complex nature of families and kinship, coping and support, use of food, and healing. These initial findings have implications for genetic counseling practice and hopefully will stimulate more qualitative social and behavioral research in cancer genetic counseling.  相似文献
