Spatial thinking is an important predictor of mathematics. However, existing data do not determine whether all spatial sub‐domains are equally important for mathematics outcomes nor whether mathematics–spatial associations vary through development. This study addresses these questions by exploring the developmental relations between mathematics and spatial skills in children aged 6–10 years (N = 155). We extend previous findings by assessing and comparing performance across Uttal et al.'s (2013), four spatial sub‐domains. Overall spatial skills explained 5%–14% of the variation across three mathematics performance measures (standardized mathematics skills, approximate number sense and number line estimation skills), beyond other known predictors of mathematics including vocabulary and gender. Spatial scaling (extrinsic‐static sub‐domain) was a significant predictor of all mathematics outcomes, across all ages, highlighting its importance for mathematics in middle childhood. Other spatial sub‐domains were differentially associated with mathematics in a task‐ and age‐dependent manner. Mental rotation (intrinsic‐dynamic skills) was a significant predictor of mathematics at 6 and 7 years only which suggests that at approximately 8 years of age there is a transition period regarding the spatial skills that are important for mathematics. Taken together, the results support the investigation of spatial training, particularly targeting spatial scaling, as a means of improving both spatial and mathematical thinking.  相似文献

The purpose of this study was to explore attitudes toward lesbians and gay men among 371 heterosexual male and female collegiate student-athletes in the USA. Attitudes were assessed in relationship to the student-athletes’ gender, sport and contact. Participants completed a demographic form and the Attitudes toward Lesbians and Gay Men (ATLG-S) Scale (Herek in Journal of Homosexuality 10:39–51, 1984, Journal of Sex Research 25:451–477, 1988). Male student-athletes were significantly more negative in their attitudes toward gay men and lesbians than females. With the exception of field hockey, there were no significant differences in the attitudes toward gay men and lesbians for student-athletes competing on different sport teams. Lastly, student-athletes that indicated having contact with gay men and/or lesbians had significantly more positive attitudes toward gay men and lesbians.  相似文献

Several decades of laboratory research have shown that high-dominant women, when paired with low-dominant men, are less likely than expected to emerge as leaders on gender-neutral tasks. The current study was designed to investigate the impact of an incentive on leadership emergence in mixed-gender pairs in which one member was high in personality dominance and one was low. Across incentive conditions, men high in personality dominance were more likely than women to emerge as leaders. Under the no-incentive condition, personality dominance relative to men did not significantly improve women’s leadership likelihood; men were more likely to emerge as leaders regardless of personality dominance. However, under the incentive condition, high-dominant women were significantly more likely to emerge as leaders than were their low-dominant male counterparts, and high-dominant men were also more likely than low-dominant women to emerge as leaders.  相似文献

This trial compared a brief group cognitive-behavioral (CBT) depression prevention program to a waitlist control condition and four placebo or alternative interventions. High-risk adolescents with elevated depressive symptoms (N=225, M age=18, 70% female) were randomized to CBT, supportive-expressive group intervention, bibliotherapy, expressive writing, journaling, or waitlist conditions and completed assessments at baseline, termination, and 1- and 6-month follow-up. All five active interventions showed significantly greater reductions in depressive symptoms at termination than waitlist controls; effects for CBT and bibliotherapy persisted into follow-up. CBT, supportive-expressive, and bibliotherapy participants also showed significantly greater decreases in depressive symptoms than expressive writing and journaling participants at certain follow-up points. Findings suggest there may be multiple ways to reduce depressive symptoms in high-risk adolescents, although expectancies, demand characteristics, and attention may have contributed to the observed effects.  相似文献

Diverse theories of psychopathology suggest that reactions to internal experiences, such as emotion, are important in the development and maintenance of psychological distress and symptomatology. This study examines the relationships between one type of reaction to emotion, fear of emotion, and reactivity to, recovery from, and interference of emotional material. As predicted, fear of emotion was related to greater increases in distress, negative affect, and skin conductance in reaction to an emotional film clip, and to greater interference of film-related material in a modified emotional Stroop task. These relationships remained when variance contributed by general negative affect was removed. Findings provide preliminary evidence that fear of emotion may be related to emotional distress and physiological arousal, and that this relationship may exist beyond shared variance due to self-report response style and general negative affectivity.  相似文献

We examined parental experience of having a child with obsessive-compulsive disorder (OCD) in 62 parent–child dyads. Youth with a primary diagnosis of OCD and their parent(s) were administered the CY-BOCS jointly by a trained clinician. Parents completed several measures about their child’s OCD-related impairment and accommodation, emotional and behavioral functioning, parental distress, caregiver stress, and parental experiences of having a child with OCD. Results indicated that parents of children with OCD are considerably distressed about their child’s condition. As expected, negative parental experiences (e.g., anxiety about child’s condition, uncertainty about their future) were directly related to OCD symptom severity and impairment, as well as child internalizing and externalizing problems, family accommodation of symptoms, and caregiver strain. The presence of emotional resources was negatively related to most outcomes, although some of these relationships did not achieve statistical significance. The presence of internalizing symptoms mediated the relationship between parental experiences and parental distress. Given these findings, addressing parental experiences as part of a family based cognitive-behavioral treatment program for pediatric OCD may help reduce parental distress and improve patient prognosis.  相似文献

This study tested Rusbult’s (1980, 1983) investment model of relationship commitment and stability using data from both partners of 3,627 married couples. As pre-dicted, spouses’ satisfaction, investments, and quality of alternatives were unique predictors of their commitment to the marital relationship. Additionally, commitment assessed at the initial testing predicted marital termination or stability 18 months later. Multiple-group path analyses showed that the investment model provided an adequate fit to the data and that the associations among variables were similar for husbands and wives. Limitations of the model as well as directions for future research are consid-ered. This research used the American Couples, 1975-1978, data set [made accessible in 1992, computer data]. These data were collected by Philip Blumstein and Pepper Schwartz and are available through the archive of the Henry A. Murray Research Center of Radcliffe College, Cambridge, Massachusetts (Producer and Distributor). This paper is based on work supported under a National Science Foundation Graduate Fellowship awarded to Emily A. Impett and a UCLA Academic Senate Research Grant to Letitia Anne Peplau. The authors are very grateful to Kevin Kim and Jodie Ullman for statistical consulting and Brian Doss for comments on an earlier draft.  相似文献
