The present study examines the potential of sequencing a neurocognitive intervention with behavioral parent training (BPT) to improve executive functions (EFs), psychiatric symptoms, and multiple indices of functional impairment in school-age children aged 7 to 11 years who have been diagnosed with attention-deficit/hyperactivity disorder (ADHD). Specifically, in a randomized controlled trial design, 85 children were assigned to either Cogmed Working Memory Training (CWMT) followed by an empirically supported, manualized BPT intervention, or to a placebo version of CWMT followed by the same BPT intervention. Working memory maintenance (i.e., attention control/short-term memory), working memory processing and manipulation, ADHD and oppositional defiant disorder (ODD) symptoms, impairment in parent–child dynamics, familial impairment, and overall functional compromise were evaluated as outcomes. The results suggest specific effects of the combined CWMT and BPT program on verbal and nonverbal working memory storage and nonverbal working memory processing and manipulation but no incremental benefits in regard to ADHD symptoms, ODD symptoms, and functional outcomes. The present findings do not support the hypothesis regarding the complementary and augmentative benefits of sequenced neurocognitive and BPT interventions for the treatment of ADHD. These results, the study’s limitations, and future directions for research are further discussed.  相似文献

When the association between emotion and well-being is being considered, positive emotions usually come to mind. However, negative emotions serve important adaptive functions and particular negative emotions may be especially adaptive at different stages of adult development. We examined the associations between self-reported negative emotions in response to an emotionally neutral, thematically ambiguous film and subjective well-being among 76 young (age 20-29), 73 middle-aged (age 40-49), and 73 older (age 60-69) adults. Results indicated that higher self-reported anger in response to the film was associated with higher well-being for middle-aged adults, but not for young and older adults. Higher self-reported sadness in response to the film was associated with higher well-being for older adults, but not for young and middle-aged adults. These findings were stronger for cognitive well-being (i.e., satisfaction with life) than for affective well-being (i.e., ratio of dispositional positive to negative affect) and were specific to these emotions (not found for self-reported disgust or fear) and to the emotionally neutral film (not found for sad or disgusting films). Results are discussed in terms of the functions that anger and sadness are thought to serve and the control opportunities afforded in midlife and late life that render these functions differentially adaptive.  相似文献

Reports an error in "Do social networks explain 12-step sponsorship effects? A prospective lagged mediation analysis" by Kristina N. Rynes and J. Scott Tonigan (Psychology of Addictive Behaviors, Advanced Online Publication, Sep 5, 2011, np). There is an error in the last paragraph of the Participants section. It was reported that 14.8% of the sample were Asian, however, 14.8% of the participants were American Indian or Alaskan Native and no participants were Asian. (The following abstract of the original article appeared in record 2011-20052-001.) Sponsorship is a basic and important part of the 12-step approach to recovery from substance abuse (Alcoholics Anonymous, 2005) and research has shown that having a sponsor is associated with increased involvement in 12-step programs and improved outcomes (Bond, Kaskutas, & Weisner, 2003; Tonigan & Rice, 2010). However, little is known about how sponsorship improves outcomes. Given research demonstrating bivariate associations between sponsorship and social support for abstinence (Majer, Jason, Ferrari, Venable, & Olson, 2002), we hypothesized that the association between having a sponsor and increased abstinence outcomes would be explained by increases in one's abstinence-based social network. Prospective fully lagged mediational analyses did not support this hypothesis and these results ran counter to findings of five previous studies (cf. Groh, Jason, & Keys, 2008). A review of these studies showed that researchers often used cross-sectional or partially lagged methods to test mediation and the mediational effect of the social network was small in magnitude. Results suggest that the prospective association between sponsorship and abstinence is not explained by increases in the abstinence-based social network and demonstrate the need for future studies to use rigorous and time-lagged methods to test social support for abstinence as a mediator of the effects of 12-step involvement.

This research examined the relation between mothers' responses to children's questions about interparent conflict and children's adjustment. Participants were 134 mothers and their children (70 boys, 64 girls), aged 7 to 10. In each family, an act of intimate-partner violence (IPV) had recently occurred. Mothers' responses to children's questions about interparent conflict were assessed via a semistructured interview coded to reflect the extent to which the mothers' responses addressed the content of the children's questions. Mothers and children reported on physical IPV. Mothers also reported on interparent conflict, parent-child aggression, and maternal warmth. Children's adjustment was assessed via mothers' and children's reports at two time points 6 months apart. The extent to which mothers' responses addressed the content of the children's questions about interparent conflict was negatively associated with children's adjustment problems, after accounting for the frequency of physical IPV, frequency of interparent conflict, parent-child aggression, and maternal warmth. These associations emerged cross-sectionally and prospectively. However, in those prospective analyses that accounted for children's baseline levels of adjustment, maternal responsiveness was not associated with later children's adjustment problems.  相似文献

We proposed two distinct understandings of what justice means to victims and what its restoration entails that are reflected in individual‐level justice orientations. Individuals with a retributive orientation conceptualize justice as the unilateral imposition of just deserts against the offender. In contrast, individuals with a restorative orientation conceptualize justice as achieving a renewed consensus about the shared values violated by the offence. Three studies showed differential relations between these two justice orientations and various individual‐level values/ideologies and predicted unique variance in preferences for concrete justice‐restoring interventions, judicial processes and abstract justice restoration goals. The pattern of results lends validity to the understanding of justice as two distinct conceptualizations, a distinction that provides much needed explanation for divergent preferences for injustice responses.

Most research on couple communication patterns comes from North America and Europe and suggests cross-cultural universality in effects, but emerging studies suggest that couple communication takes different forms depending on the cultural context in which it occurs. The current study addressed this discrepancy by comparing the observed social support behaviors of 50 newlywed American couples and 41 newlywed Mainland Chinese couples, first on mean levels of positivity and negativity and second on behavior-satisfaction associations. Consistent with predictions derived from observational work by Tsai and Levenson (1997), Chinese couples were observed displaying significantly more negative behavior than American couples, even after controlling for relationship satisfaction; the 2 groups did not differ in observed positive behaviors. Tests of the moderating role of culture on behavior-satisfaction associations showed that positivity was significantly related to relationship satisfaction only for American husbands, whereas negativity was significantly associated with relationship satisfaction only for Chinese husbands. We speculate that cultural contexts may influence the display and evaluation of behavior in intimate relationships, suggesting the need for caution when generalizing models and associated interventions to non-Western couples.  相似文献

Age-related declines in associative memory are proposed to result from deficits in older adults' ability to recollect the past. The present experiment investigated the ability of older adults to compensate for deficits in recollecting the past by using plausibility. Participants studied a list of word pairs that shared category or rhyme relations. To measure the processes used during the recognition memory test, participants provided self-reported explanations for their memory judgements. Older adults relied primarily on plausibility, and the younger adults relied on both plausibility and recollection. Older adults experienced both positive and negative consequences as a result of using a knowledge-based strategy to compensate for their decreased ability to recollect the past. Specifically, they were just as capable as younger adults at recognising previously studied items and correctly rejecting distractors that were inconsistent with the rule provided at study. However, they falsely recognised distractors that were consistent with that rule more often than younger adults.  相似文献

Recent evidence suggests that, compared with hearing people, deaf people have enhanced visual attention to simple stimuli viewed in the parafovea and periphery. Although a large part of reading involves processing the fixated words in foveal vision, readers also utilize information in parafoveal vision to preprocess upcoming words and decide where to look next. In the study reported here, we investigated whether auditory deprivation affects low-level visual processing during reading by comparing the perceptual span of deaf signers who were skilled and less-skilled readers with the perceptual span of skilled hearing readers. Compared with hearing readers, the two groups of deaf readers had a larger perceptual span than would be expected given their reading ability. These results provide the first evidence that deaf readers' enhanced attentional allocation to the parafovea is used during complex cognitive tasks, such as reading.  相似文献
