Some children make impulsive choices (i.e., choose a small but immediate reinforcer over a large but delayed reinforcer). Previous research has shown that delay fading, providing an alternative activity during the delay, teaching participants to repeat a rule during the delay, combining delay fading with an alternative activity, and combining delay fading with a countdown timer are effective for increasing self‐control (i.e., choosing the large but delayed reinforcer over the small but immediate reinforcer). The purpose of the current study was to compare the effects of various interventions in the absence of delay fading (i.e., providing brief rules, providing a countdown timer during the delay, or providing preferred toys during the delay) on self‐control. Results suggested that providing brief rules or a countdown timer during the delay was ineffective for enhancing self‐control. However, providing preferred toys during the delay effectively enhanced self‐control.  相似文献

Sixty‐two preschoolers (55% boys) were presented hypothetical dilemmas about moral transgressions. Responses were evaluated in terms of children's emotional responsiveness, prosocial motives, and readiness to intervene. Mothers and fathers reported separately on their use of victim‐oriented inductions, teaching reparations, power assertion, and love withdrawal. Four years later, parents reported on children's behavioral problems, emotion‐regulation ability, and empathy. Mothers reported using more victim‐oriented inductions than did fathers, and girls responded with more personal distress and reported more rule‐oriented motives. Maternal love withdrawal was a positive predictor of empathy and motives of concern. For fathers, teaching reparations were positively related to children's sympathy. Interestingly, mothers' power assertion was negatively related to sympathy at high levels of fathers' power assertion, but not at low levels. Maternal power assertion during the preschool years was negatively associated with children's long‐term empathy scores. School‐age outcomes also were meaningfully predicted by earlier sociomoral competence.  相似文献

This controlled study examined the effects of dividing attention between walking and the performance of a secondary cognitive task in people with mild to moderate Parkinson's disease (Hoehn and Yahr stages 2-3.5). Participants in the training group (n=6) received 30 min divided attention training in taking big steps while simultaneously performing serial three subtractions. Participants in the control group (n=6) received no training. Stride length, gait velocity and accurate enumeration rate were measured at baseline, immediate after training and 30 min after training under single-task (walk only or subtract only) and dual-task (walk and subtract) conditions. Data were also collected at training in the training group. Immediate improvement in stride length and gait velocity was found when instruction was given to participants to pay equal attention to gait and subtractions (p=0.001, p=0.05) compared to baseline. Short-term improvement in the gait variables was also found after training when compared to the controls (p=0.001, p=0.001). Nevertheless, there was no significant difference in the accurate enumeration rate. Based on the findings, we conclude that divided attention can be used as a strategy to improve slow and short-stepped gait under dual-task conditions. Divided attention can also be used in gait training for short term stride length and gait velocity improvement.  相似文献

This article reviews progress made in the theory and practice of pastoral care and counseling with regard to the issue of intimate violence against women since the 1970’s. It includes a comprehensive survey of sociological, psychological, and pastoral literature, and a summary of research on teaching about domestic violence in mainline Protestant seminaries. Social and theological themes, including gender, power, and social and political context, and the challenges of justice-making are traced historically. The article concludes with new recommendations for churches, pastoral caregivers, counselors, and theologians.  相似文献

Youth with neurofibromatosis type 1 (NF1) have multiple, complex symptoms associated with physical, social-emotional, and cognitive difficulties. In addition, caring for a child with NF1 can be extremely challenging for parents. Since research with other chronic illness populations suggests that social support, including internet support groups (ISGs), can be beneficial, this survey study aimed to determine the attitudes and preferences of adolescents and young adults with NF1 and parents of a child with NF1 regarding ISGs. Thirty patients and 30 caregivers completed a 24-item survey about ISGs. Many patients and parents are not aware of any ISGs for NF1, but are interested in using one in the future for a variety of reasons, including to get answers to their questions about NF1, to find out about research studies, and to discuss problems and concerns about NF1. Specific concerns of interest include physical, social-emotional, and cognitive aspects of NF1. ISGs have potential as a social support intervention within the NF1 community. ISGs for the NF1 population should include patients with NF1 (or parents of children with NF1) as well as a health professional, and both chat rooms and discussion boards likely would be well-received.  相似文献

Research has demonstrated an association between perfectionism and depressive and anxious symptoms in children. We examined whether a school-based program targeting anxious and depressive symptoms would reduce perfectionism, and whether perfectionism would interfere with intervention outcomes. The participants were 78 school-age children identified as at-risk for anxiety and/or depression. At-risk children took part in a randomized controlled trial of a school-based intervention program. Levels of perfectionism, depression, and anxiety were assessed at pre-treatment (Time 1) and again at post-treatment (Time 2) after participating in either a cognitive behavioral group or a structured activity group. Participation in either group was associated with significant reductions in overall levels of self-oriented perfectionism, anxious symptoms, and depressive symptoms. Supplementary analyses indicated that pre-treatment self-oriented perfectionism influenced post-treatment depression scores, suggesting that perfectionism interferes with treatment outcome. Perfectionism in children appeared amenable to group-based intervention, and identifying perfectionism may be important for treating children with depressive symptoms.  相似文献

In lieu of the traditional text data analysis methods, structural topic modeling was utilized to analyze the text contents of 255 self-report inventories of religion and spirituality (R/S) published from 1929 to 2017. The study had two objectives: (a) to clarify and identify the latent dimensions of R/S inherent in the items of the measures; and (b) to examine and demonstrate the usefulness of a longitudinal topic modeling in the study of R/S. We identified 5,617 unique text terms from the measures and fitted topic models on those terms to extract latent dimensions called topics. We also simultaneously analyzed the longitudinal effect of publication decade (i.e., 1950s–2010s) on the topics. A topic model with three topics was chosen to best support the data: Experience of Transcendence (Topic 1), Engagement in Transcendence (Topic 2), and Essence of Transcendence (Topic 3). In addition, the longitudinal analysis revealed that Topic 1 showed a continual increase over the decades, while Topics 2 and 3 both demonstrated a gradual decrease, in effect matching the general trend of Topic 1's increasing popularity in society and the academia.  相似文献

Testing can improve later recall of information. However, much less is known about the potential use of testing in promoting the transfer of learning. In this study, we investigated whether testing improves decision‐making performance on a transfer task in a sample of 98 university students using a between‐subjects design. After studying several statements about a fictional disease under different learning conditions (restudy, free recall, and multiple‐choice), participants were asked to recall this information and subsequently make medical decisions concerning the fictional disease (i.e., the transfer task). The present study found no advantage of testing conditions over restudy condition on the 30‐min delayed memory task. However, participants in the active retrieval practice (i.e., free recall) group performed significantly better on the transfer task over those in both restudy and multiple‐choice groups. These results suggest free‐recall tests promote the transfer of learning.  相似文献
