Breast cancer impacts an entire family system. The mothers of breast cancer patients are likely impacted in a variety of ways by their daughters’ diagnoses. To date, few researchers have investigated the experiences and perspectives of this population. In the present study, the authors explored how mothers of breast cancer survivors managed adversities associated with this disease and illness. Using secondary data and narrative analysis, the investigators analyzed data gathered from 30 mothers. Findings indicate that participants relied on their spirituality for the management of stress and hardship related to having a loved one with breast cancer.  相似文献

We compared the effects of three types of visual aid on free recall across three age groups in an eyewitness paradigm. Child, adolescent and adult participants (N = 144) viewed a short film depicting a non‐violent crime and, following a brief delay, gave a free‐recall account. Participants then described the event once again, with the aid of their own sketch plan, a provided sketch plan or photograph, or with no visual aid. Interviews were transcribed verbatim and coded for the type and accuracy of information reported. Across all age groups, relative to the control condition, all three visual aids increased the amount of new information reported during the second free‐recall account and helped participants to maintain accuracy. All three visual aids therefore had a positive effect on participants' performance; in a forensic setting, however, witnesses' own sketch plans are likely to be the safest, most easily applied and most time effective.Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Despite a vast body of literature evidencing the negative effects of workplace sexual harassment it remains unclear whether sexual harassment experienced by the target is worse when the harasser is a supervisor, rather than a coworker. With a scenario‐based experimental study we examined whether targets harassed by their supervisor would experience greater decreases in overall job satisfaction than those targeted by a coworker. Results suggested that harasser status moderated the effects of sexual harassment on overall job satisfaction but only for female targets. Further, the effect of supervisor harassment on job satisfaction was mediated by interpersonal justice perceptions.  相似文献

Understanding the social context of classrooms has been a central goal of research focused on the promotion of academic development. Building on the current literature on classroom social settings and guided by a risk and protection framework, this study examines the unique and combined contribution of individual relationships and quality of classroom interactions on behavioral engagement among low‐income Latino students in kindergarten to fifth grade (= 111). Findings indicate that individual relationships with teachers and peers and classroom quality, each independently predicted behavioral engagement. Moreover, high‐quality classrooms buffered the negative influence of students’ difficulties in individual relationships on behavioral engagement. Findings illuminate the need to consider multiple layers of social classroom relationships and interactions and suggest the potential benefit of targeting classroom quality as a mechanism for improving behavioral engagement in urban elementary schools.  相似文献

In the present article, we extend a model of relational spirituality and forgiveness to the context of major offenses by clergy. In Study 1, undergraduate students (N = 208) described a major offense that they had experienced by a religious leader and then completed several questionnaires in relation to the offense and the religious leader. Appraisals of relational spirituality were significantly associated with forgiveness, after controlling for known predictors of forgiveness (i.e., hurtfulness, time since the offense, and commitment to God or another source of spirituality). In Study 2, we replicated and extended the findings from Study 1 using an independent sample of undergraduates (N = 365). In a series of structural equation models, we found that relational engagement of God (or another source of spirituality) partially mediated the relationship between anger toward God (or another source of spirituality) and unforgiving motivations. We conclude by discussing implications for future research.  相似文献

Sex on television has been a topic of interest to scholars and critics alike. History has shown that certain programs break the mold when talking about sex. One show that is currently leading this trend is HBO’s Girls, a fictional comedy-drama show with 4.1 million viewers that has received much attention for its portrayals of sex. This systematic, quantitative content analysis is a case study of the first three seasons of Girls. It examines sexual behaviors, sexual talk, and sexual risk and responsibility. Results revealed kissing to be the most prevalent sexual behavior and talking about own or other’s sexual interests/actions was the most frequent form of sexual talk. Most surprisingly, sexual risk/responsibility was represented much more in Girls than in shows evaluated in previous television content analyses.  相似文献

Cataglyphis cursor worker ants are capable of highly sophisticated rescue behaviour in which individuals are able to identify what has trapped a nestmate and to direct their behaviour towards that obstacle. Nonetheless, rescue behaviour is constrained by workers’ subcaste: whereas foragers, the oldest workers, are able both to give and to receive the most help, the youngest workers, inactives, neither give nor receive any help whatsoever; nurses give and receive intermediate levels of aid, reflecting their intermediate age. Such differences in rescue behaviour across subcastes suggest that age and experience play a critical role. In this species, as in many others in which a sensitive period for nestmate recognition exists, newly enclosed ants, called callows, are adopted by ants belonging not only to different colonies but also to different species; foreign callows receive nearly the same special care provided to resident newborns. Because callows are younger than inactives, which are incapable of soliciting rescue, we wondered whether entrapped callows would receive such aid. In the present study, we artificially ensnared individual callows from their own colony (homocolonial), from a different colony (heterocolonial), and from a different species (heterospecific), and tested each one with groups of five potential C. cursor rescuers, either all foragers or all nurses. Our results show that all three types of callows are able to elicit rescue behaviour from both foragers and nurses. Nonetheless, nurse rescuers are better able to discriminate between the three types of callow victims than are foragers.  相似文献

Deep semantic encoding of verbal stimuli can aid in later successful retrieval of those stimuli from long-term episodic memory. Evidence from numerous neuropsychological and neuroimaging experiments demonstrate regions in left prefrontal cortex, including left dorsolateral prefrontal cortex (DLPFC), are important for processes related to encoding. Here, we investigated the relationship between left DLPFC activity during encoding and successful subsequent memory with transcranial magnetic stimulation (TMS). In a pair of experiments using a 2-session within-subjects design, we stimulated either left DLPFC or a control region (Vertex) with a single 2-s train of short theta burst stimulation (sTBS) during a semantic encoding task and then gave participants a recognition memory test. We found that subsequent memory was enhanced on the day left DLPFC was stimulated, relative to the day Vertex was stimulated, and that DLPFC stimulation also increased participants’ confidence in their decisions during the recognition task. We also explored the time course of how long the effects of sTBS persisted. Our data suggest 2 s of sTBS to left DLPFC is capable of enhancing subsequent memory for items encoded up to 15 s following stimulation. Collectively, these data demonstrate sTBS is capable of enhancing long-term memory and provide evidence that TBS protocols are a potentially powerful tool for modulating cognitive function.  相似文献

Young children have an overall preference for child‐directed speech (CDS) over adult‐directed speech (ADS), and its structural features are thought to facilitate language learning. Many studies have supported these findings, but less is known about processing of CDS at short, sub‐second timescales. How do the moment‐to‐moment dynamics of CDS influence young children's attention and learning? In Study 1, we used hierarchical clustering to characterize patterns of pitch variability in a natural CDS corpus, which uncovered four main word‐level contour shapes: ‘fall’, ‘rise’, ‘hill’, and ‘valley’. In Study 2, we adapted a measure from adult attention research—pupil size synchrony—to quantify real‐time attention to speech across participants, and found that toddlers showed higher synchrony to the dynamics of CDS than to ADS. Importantly, there were consistent differences in toddlers’ attention when listening to the four word‐level contour types. In Study 3, we found that pupil size synchrony during exposure to novel words predicted toddlers’ learning at test. This suggests that the dynamics of pitch in CDS not only shape toddlers’ attention but guide their learning of new words. By revealing a physiological response to the real‐time dynamics of CDS, this investigation yields a new sub‐second framework for understanding young children's engagement with one of the most important signals in their environment.  相似文献

Certain potential precursors to heterosexual women's experience of partner infidelity are explored as these dynamics unfold within the oedipal crisis-the "betrayal" by the oedipal objects. As each child moves into the oedipal phase, he or she comes to recognize not only desire for the mother, but the mother's desire for the father. A doubling of this experience of "deception," encountered first in relation to the mother, and then repeated with the father, may be especially pronounced for a girl, as she is likely to inhabit more fully her bisexual potential in negotiating the expected shift of object choice from mother to father. "Deceived" by her primary maternal oedipal object, a girl sets forth toward her paternal oedipal object with "fidelity" already an issue, and with faith in her mind's ability to determine reality already shaken. Undermined trust in self and other is the context in which she begins the oedipal relation to her heterosexual object. This path is quite distinct from that traveled by the heterosexual boy. Clinical material illustrates the assault on one's mind, on one's confidence to determine what is true, that is a central aspect of both oedipal and adult betrayal.  相似文献
