Our capacity to perceive three-dimensional (3D) object structure from two-dimensional (2D) retinal input is fundamental to object perception. The present research examined infants’ ability to extract 3D form from structure-from-motion (SFM) displays using a familiarization/visual-paired-comparison paradigm. In SFM displays dots are projected onto the surfaces of a shape that rotates around a 3D axis and it is the coherent structure of the dots’ motion that gives rise to the percept of shape. Infants mean age 4.5 and 9 months were familiarized to a SFM display (e.g., cylinder); in test they were presented the familiar SFM display paired with a novel SFM display (e.g., cube). Infants in both age groups displayed a significant preference for the novel SFM test display. These results are consistent with those obtained previously using habituation paradigms and provide converging evidence for infants’ early emerging capacity to use coherent motion – in the absence of figural information – as a cue to depth structure. In addition, these results demonstrate that infants’ ability to extract 3D shape from coherent motion can be successfully assessed with a neuroimaging-friendly protocol, which was one of the goals of this study.  相似文献

This study examined how sensitive support provision and receipt were related to marital outcomes in a sample of 57 happily married, middle-class couples from the Midwestern U.S. To assess how observed supportive behaviors may be differentially associated with self-reported support satisfaction, marital love, and marital conflict for men and women, we utilized a series of Actor Partner Interdependence Models (APIM). This dyadic approach revealed significant gender differences regarding how the supportive role enacted (i.e., provider versus recipient) contributed considerably to marital outcomes. Specifically, husbands’ sensitive support provision significantly predicted both spouses’ support satisfaction. Additionally, husbands’ sensitive support provision was significantly associated with wives’ marital love. Wives’ reported conflict was predicted by the combination of both providing and receiving sensitive support. For husbands’ outcomes, husbands’ own sensitive support provision was most critically associated with their reporting greater love and less conflict. These findings reveal notable gender differences as men’s ability to provide sensitive support was critical not only to their wives’ marital outcomes, but to their own as well. Our results build upon and extend the literature implicating the importance of examining gender differences in supportive interactions in marriage. Moreover, our findings suggest that simultaneous consideration of spousal support receipt and provision is critical when seeking to understand how support is related to marital outcomes for men and women.  相似文献

Younger women diagnosed with cancer often face compromised fertility as a result of their treatment. However, previous research has adopted a biomedical model of fertility and utilised hypothetico-deductive research methods which have not allowed for full exploration of women’s subjectivity. This study explored younger women’s construction of their fertility post-cancer, and their discussions of fertility with healthcare professionals, from a social constructionist epistemology. Semi-structured one-to-one interviews were conducted with eight women aged 18–26, across a variety of cancer types. Foucaultian Discourse Analysis identified three subject positions associated with fertility concerns: ‘Inadequate woman: Accepting the motherhood mandate’; ‘Adequate woman: Resisting the motherhood mandate’; and ‘Survival of the fittest: Woman as genetically defective’. Implications of these subject positions included feelings of inadequacy, fear and devastation; feeling undesirable to romantic partners; and concern about passing on cancer-positive genes. In describing healthcare professional interactions, women adopted positions of ‘Satisfied patient’; ‘Passive recipient patient’; or ‘Resisting the passive patient position’. Accounts of inadequate information provision were associated with anger and frustration, whereas feeling adequately informed was associated with satisfaction at making decisions about fertility preservation. These results suggest that fertility is of importance to young women cancer survivors, and that compromised fertility can negatively impact subjectivity.  相似文献

Cancer patients experience positive as well as adverse consequences from cancer diagnosis and treatment. The work reported here was part of an effort to characterize the experiences of benefit finding in breast cancer patients. A sample of 230 early-stage breast cancer patients completed a set of benefit finding items in the year post-surgery. This measure was then related to measures of concurrent coping, several aspects of psychosocial well-being, demographic variables, and several other personality traits. Benefit finding related positively to trait optimism, and to positive reframing and religious activity as coping reactions. Benefit finding related inversely to emotional distress, but was relatively unrelated to other measures of well-being.  相似文献

Adverse sequelae of prenatal alcohol exposure include executive function and social skills impairments, although these two domains have not been empirically linked in alcohol-exposed individuals. This study investigated this relationship using the BRIEF and the SSRS in 98 children aged 6 to 11 years. Executive functions explained a significant percentage of variance in parent and teacher rated social skills. No differences were found among children with diagnoses of FAS, partial FAS, or alcohol-related neurodevelopmental disorder. It may be helpful to consider executive functioning in designing social skills interventions for alcohol-exposed children whether or not they have full FAS.  相似文献

Using a longitudinal Web-based survey of adolescents 14–16 years of age, we estimate regression models where self-reported sexual behavior and content analytic-based exposure to sex in the media are related cross-sectionally and longitudinally. We find evidence for both cross-sectional nonrecursive and prospective longitudinal relationships even after adjusting for both established predictors of sexual behavior (e.g., physical development, having a romantic partner, parental monitoring, peer and parental norms, respondent's age) and of exposure to sexual media content (e.g., time the respondent goes to bed, extracurricular activities, television in the bedroom, total time spent with television, music, video games, and magazines). Sexually active adolescents are more likely to expose themselves to sex in the media and those exposed to sex in the media are more likely to progress in their sexual activity. These findings are consistent with others in the literature that demonstrate a causal effect of exposure to sexual content on sexual behavior but extend established results by also looking at the causal effect of sexual behavior on exposure both cross-sectionally and over time.  相似文献

BACKGROUND: Depression and suicidality are frequently reported in patients with psychosis and schizophrenia, but the grief process that may be associated with this illness has not been systematically studied. In this study, we examined whether patients diagnosed with psychosis identify, grieve, and mourn losses engendered by the illness. METHOD: 24 patients diagnosed with psychosis in the past five years were surveyed to indicate whether their illness led to losses, and to describe their responses to the losses. Psychosis-related perceived losses were surveyed using three subscales of a loss and grief questionnaire (loss of self, self-care, and roles). Their relationship with beliefs about the illness, symptomatology, coping style, and self-efficacy and insight was studied. RESULTS: 23 (96%) patients named specific losses, and 16 patients (67%) reported feelings associated with grief and mourning. More than half reported loss of self-esteem at the onset of illness and only half saw themselves as having improved in the past month. Patients reported more loss within the past month than at the onset of illness. In the past month, patients with an intact sense of self experienced greater self-efficacy (r = .568, p < .004) while those with loss of self reported feelings of shame (r = ?.582, p < .003). Only patients with insight associated the onset of illness with loss. In the past month, most patients saw themselves as experiencing loss. DISCUSSION: The study results suggest that at some distance from diagnosis, patients still experience themselves as having much loss due to their illness. These unresolved feelings may indicate complicated mourning. Insight appears to be associated with the ability to look back at the onset of the illness and recognize that it engendered losses. Further study of the process of and barriers to grief and mourning is recommended. In clinical practice, the assessment of grief as a part of post-psychotic recovery could lead to providing more appropriate treatment and lead to a positive outcome.  相似文献

An experimental methodology was adapted to examine children's language skills and mothers' conversational styles during a specified event as they are linked to the children's event memory. Thirty-nine preschoolers (mean age = 46.82 months) were pretested and grouped as having high or low language skills. Children in each group were then randomly assigned to either maternal-style training or no training conditions. Trained mothers were instructed to use 4 specific conversational techniques to enhance children's understanding of unfolding events: Wh- questions, associations, follow-ins, and positive evaluations. When observed engaging with their children in a specially constructed camping activity, trained mothers did indeed use these elements of style more than untrained mothers. Moreover, assessments of the children's memory after 1-day- and 3-week-delay intervals indicated substantial effects of both maternal training and children's language skills on remembering.  相似文献

Abstract

Although many studies have examined the nature of memory distortions in anxious individuals, few have considered biases in specific memory processes, such as encoding or retrieval. To investigate whether the presentation of threat material facilitates encoding biases, spider fearful (n=63), blood fearful (n=73), and nonfearful (n=75) participants encoded spider related, blood related, and neutral words as a function of three levels of processing (i.e., structural, semantic, and self referent). Participants subsequently completed either a free recall or a recognition task. All participants demonstrated a partial depth of processing effect, such that they recalled more words encoded in the self referent condition than in the other two conditions, but groups did not differ in their recall of stimuli as a function of word type. Relative to participants in the other groups, spider fearful participants had fewer spider related intrusions in the recall condition, and they made fewer errors in responding to structural and semantic encoding questions when spider related words were presented. These results contribute to an increasingly large body of literature suggesting that anxious individuals are not characterized by a memory bias toward threat, and they raise the possibility that individuals with spider fears process threat-relevant information differently than individuals with blood fears.  相似文献

ABSTRACT

Summative evaluation plays a critical role in documenting the impacts of informal science education (ISE), potentially contributing to the ISE knowledge base and informing ongoing improvements in practice and decision-making. In response to the growing demand for capacity-building in ISE evaluation, this article presents a framework for summative evaluation based on an extensive review of literature and research-based refinements. The framework synthesizes key elements of high-quality summative evaluation into three dimensions: (a) Intervention Rationale, (b) Methodological Rigor and Appropriateness, and (c) Evaluation Uses. Judgment of the value of the intervention (e.g., program, exhibition) should draw upon all three dimensions.  相似文献
