Individuals can quickly and effortlessly recognize facial expressions, which is critical for social perception and emotion regulation. This sensitivity to even slight facial changes could result in unstable percepts of an individual’s expression over time. The visual system must therefore balance accuracy with maintaining perceptual stability. However, previous research has focused on our sensitivity to changing expressions, and the mechanism behind expression stability remains an open question. Recent results demonstrate that perception of facial identity is systematically biased toward recently seen visual input. This positive perceptual pull, or serial dependence, may help stabilize perceived expression. To test this, observers judged random facial expression morphs ranging from happy to sad to angry. We found a pull in perceived expression toward previously seen expressions, but only when the 1-back and current face had similar identities. Our results are consistent with the existence of the continuity field for expression, a specialized mechanism that promotes the stability of emotion perception, which could help facilitate social interactions and emotion regulation. 相似文献

A functional neuroimaging analysis of the Trail Making Test-B: implications for clinical application
Recent progress has been made using fMRI as a clinical assessment tool, often employing analogues of traditional "paper and pencil" tests. The Trail Making Test (TMT), popular for years as a neuropsychological exam, has been largely ignored in the realm of neuroimaging, most likely because its physical format and administration does not lend itself to straightforward adaptation as an fMRI paradigm. Likewise, there is relatively more ambiguity about the neural systems associated with this test than many other tests of comparable clinical use. In this study, we describe an fMRI version of Trail Making Test-B (TMTB) that maintains the core functionality of the TMT while optimizing its use for both research and clinical settings. Subjects (N=32) were administered the Functional Trail Making Test-B (f-TMTB). Brain region activations elicited by the f-TMTB were consistent with expectations given by prior TMT neurophysiological studies, including significant activations in the ventral and dorsal visual pathways and the medial pre-supplementary motor area. The f-TMTB was further evaluated for concurrent validity with the traditional TMTB using an additional sample of control subjects (N=100). Together, these results support the f-TMTB as a viable neuroimaging adaptation of the TMT that is optimized to evoke maximally robust fMRI activation with minimal time and equipment requirements. 相似文献

Behavioural parenting programs are an effective intervention for behavioural and emotional problems in children, however these
programs have low utilisation rates by culturally diverse parents. We examined the cultural acceptability of program materials,
preferences for delivery methods, and barriers to use of the Triple P-Positive Parenting Program. One hundred and thirty seven
parents watched a video outlining the 17 strategies in Triple P and read through a tip sheet before completing a series of
questionnaires. Results revealed that parents found the strategies highly acceptable, highly useful, were very likely to use
the strategies and reported currently using the strategies often. They also rated the program materials as very culturally
appropriate and identified group, seminar, television, and individual as the most preferred delivery methods. Parents identified
location and timing of services, financial cost, and competing work commitments as the most frequently cited barriers to accessing
a parenting intervention. The findings of this study suggest that elements of parenting programs may not be contributing to
the low rates of access among culturally diverse parents. These findings highlight the need for more research addressing variables
that may contribute to increasing culturally diverse parents’ access of behavioural parenting programs. 相似文献

There is a paucity of research considering the effect of behavioral family intervention (BFI) on parenting knowledge and the relative importance of both knowledge and parent confidence in reducing parenting dysfunction and problematic child behavior is unclear. In this study ninety-one parents (44 mothers, 47 fathers) of children aged 2–10?years completed an evidence-based BFI and were assessed at pre and post-intervention on knowledge of effective parenting strategies, parenting confidence, parent dysfunction, and reported intensity of externalised child behavior. Results showed that at pre-intervention parents higher in education (N?=?57) demonstrated greater knowledge than those lower in education (N?=?34). Relative to baseline, parents in both groups significantly improved their knowledge and confidence, reduced their dysfunction and reported less externalised child behavior. Effect sizes for the latter two variables were similar for both groups, however for parents higher in education the effect for confidence was larger than knowledge. Change in level of dysfunction explained the largest amount of unique variance in change to externalised child behavior. Results suggest that for optimal outcomes for parenting and child behavior management more knowledgeable parents may benefit from interventions that focus on practice and consolidation of already learned skills in order to increase confidence whereas for less knowledgeable parents the teaching of new skills and strategies, alongside increasing confidence, are important. 相似文献

Motivational interviewing is a directive, non-confrontational intervention to promote behavior change. The current study examined therapist behaviors during a successful brief motivational interviewing intervention for physically aggressive college dating couples (Woodin & O'Leary, 2010). Forty-five minute motivational interviews with each partner were videotaped and coded using the Motivational Interviewing Treatment Integrity scale (MITI; Moyers, Martin, Manuel, & Miller, 2003). Hierarchical modeling analyses demonstrated that therapist behaviors consistent with motivational interviewing competency predicted significantly greater reductions in physical aggression perpetration following the intervention. Specifically, greater reflection to question ratios by the therapists predicted reductions in aggression for both men and women, greater percentages of open versus closed questions predicted aggression reductions for women, and there was a trend for greater levels of global therapist empathy to predict aggression reductions for women. These findings provide evidence that motivational interviewing seems to have an effect on behavior change through therapist behaviors consistent with the theoretical underpinnings of motivational interviewing. 相似文献

The 21st century has witnessed a drastic transformation in professional school counseling, fueled by calls for social justice and educational equity and characterized by a movement toward collaboration, advocacy, leadership, and systemic change to promote academic success for all students. The authors describe how this transformation is aligned with an ecological perspective, provide an overview of the basic tenets of ecological thinking, and take a first step toward developing an intentional model of ecological school counseling. 相似文献

Maintaining a stable score scale over time is critical for all standardized educational assessments. Traditional quality control tools and approaches for assessing scale drift either require special equating designs, or may be too time-consuming to be considered on a regular basis with an operational test that has a short time window between an administration and its score reporting. Thus, the traditional methods are not sufficient to catch unusual testing outcomes in a timely manner. This paper presents a new approach for score monitoring and assessment of scale drift. It involves quality control charts, model-based approaches, and time series techniques to accommodate the following needs of monitoring scale scores: continuous monitoring, adjustment of customary variations, identification of abrupt shifts, and assessment of autocorrelation. Performance of the methodologies is evaluated using manipulated data based on real responses from 71 administrations of a large-scale high-stakes language assessment. 相似文献

Memory consolidation is defined as the time window during which the memory trace is susceptible to behavioral, electrical, or pharmacological interventions. Here, we presented rats with two novel tastes at consecutive time intervals. Clear interference was evident when a novel taste formed the second taste input whereby, surprisingly, the time window for interference was found to last more than 10 h. In addition, we detected an increase of C/EBPbeta protein expression in the gustatory cortex 18 h after novel taste learning. This modulation was attenuated by a subsequent novel taste. Our findings reveal temporal constraints and a lingering nature of taste memory consolidation. 相似文献
