Children born very preterm (VPT) are at risk for academic, behavioral, and/or emotional problems. Mathematics is a particular weakness and better understanding of the relationship between preterm birth and early mathematics ability is needed, particularly as early as possible to aid in early intervention. Preschoolers born VPT (n = 58) and those born full term (FT; n = 29) were administered a large battery of measures within 6 months of beginning kindergarten. A multiple-mediation model was utilized to characterize the difference in skills underlying mathematics ability between groups. Children born VPT performed significantly worse than FT-born children on a measure of mathematics ability as well as full-scale IQ, verbal skills, visual–motor integration, phonological awareness, phonological working memory, motor skills, and executive functioning. Mathematics was significantly correlated with verbal skills, visual–motor integration, phonological processing, and motor skills across both groups. When entered into the mediation model, verbal skills, visual–motor integration, and phonological awareness were significant mediators of the group differences. This analysis provides insights into the pre-academic skills that are weak in preschoolers born VPT and their relationship to mathematics. It is important to identify children who will have difficulties as early as possible, particularly for VPT children who are at higher risk for academic difficulties. Therefore, this model may be used in evaluating VPT children for emerging difficulties as well as an indicator that if other weaknesses are found, an assessment of mathematics should be conducted.  相似文献

Affective processing is one domain that remains relatively intact in healthy aging. Investigations into the neural responses associated with reward anticipation have revealed that older and younger adults recruit the same midbrain reward regions, but other evidence suggests this recruitment may differ depending on the valence (gain, loss) of the incentive cue. The goal of the current study was to examine functional covariance during gain and loss feedback in younger and healthy older adults. A group of 15 older adults (mean age = 68.5) and 16 younger adults (mean age = 25.4) completed a revised Monetary Incentive Delay task (rMID; Knutson, Westdorp, Kaiser, &; Hommer, 2000) while in the fMRI scanner. The rMID is a reaction time task where successful performance, either gaining a reward or avoiding a loss, is defined by hitting a button during the brief presentation of a visual target. Participants receive gain and loss anticipation cues before each trial and feedback after each trial with four possible outcomes: +$5.00, +0.00, -$5.00, and -Affective processing is one domain that remains relatively intact in healthy aging.

Participants receive gain and loss anticipation cues before each trial and feedback after each trial with four possible outcomes: +$5.00, +0.00, -$5.00, and -$0.00. Using seed-voxel partial least squares analyses, with seed voxels in the caudate and ventromedial prefrontal cortex, whole-brain functional covariance revealed that younger and older adults engage the same network of regions to support general feedback processing. However, older adults engaged two additional networks to support processing of negative feedback, gain_miss (+0), loss_miss (-$5), and loss_hit (?0), specifically. These findings are in line with theories of a positivity effect in aging and may have implications for reward-stimulus learning and decision making following performance-contingent negative feedback.  相似文献

Problem-solving therapy (PST) is a psychosocial intervention, typically considered to be a member of the cognitive and behaviour therapies family, and is based on a biopsychosocial, diathesis-stress model of psychopathology. The overarching goal of this approach is to promote the successful adoption of adaptive problem-solving attitudes and the effective implementation of certain behaviours as a means of coping with life stressors in order to attenuate the negative effects of such events on physical and mental well-being. Over the past several decades, in addition to accumulating strong support for its efficacy as a clinical intervention, similar to many other forms of psychotherapy, PST has undergone various evolutionary changes. Developed primarily as a more cognitive-based approach, due to the large body of literature in the field of affective neuroscience that underscores the importance of the impact of affect on problem solving, PST has evolved into emotion-centered problem-solving therapy (EC-PST). This article provides for a brief excursion into the historical roots of PST and why it has evolved into EC-PST, as well as providing support for its characterisation as a transdiagnostic approach. In addition, several meta-analyses that underscore its efficacy are described, as well as the most recent clinical guidelines that comprise EC-PST.  相似文献

Autobiographical memories (AMs) can be used to create and maintain closeness with others [Alea, N., &; Bluck, S. (2003). Why are you telling me that? A conceptual model of the social function of autobiographical memory. Memory, 11(2), 165–178]. However, the differential effects of memory specificity are not well established. Two studies with 148 participants tested whether the order in which autobiographical knowledge (AK) and specific episodic AM (EAM) are shared affects feelings of closeness. Participants read two memories hypothetically shared by each of four strangers. The strangers first shared either AK or an EAM, and then shared either AK or an EAM. Participants were randomly assigned to read either positive or negative AMs from the strangers. Findings suggest that people feel closer to those who share positive AMs in the same way they construct memories: starting with general and moving to specific.  相似文献

Is the state a collective agent? Are citizens responsible for what their states do? If not citizens, then who, if anyone, is responsible for what the state does? Many different sub‐disciplines of philosophy are relevant for answering these questions. We need to know what “the state” is, who or what it's composed of, and what relation the parts stand in to the whole. Once we know what it is, we need to know whether that thing is an agent, in particular a moral agent capable of taking moral responsibility for its actions. We have to know what it takes for it to be capable of moral responsibility, e.g., what the functional equivalents in groups (or in that kind of group in particular) are of knowledge, intention, foreseeability, recklessness, and so on. And once we've established that it is an agent, and is responsible for what it does, we have to explain whether and in what way this implicates members, i.e., whether state responsibility distributes to the (compositional) members of states, whoever they may be (“citizens” is one possibility, but there are many). Answers to these questions come from metaphysics, social ontology, action theory, epistemology, political theory, and ethics. In what follows, we'll give an outline of some different ways of answering these questions.  相似文献

Mechanisms for extending autonomy in financial and health care decisions (e.g., advanced directives) are being utilized more frequently. This study examined the hierarchy of documents completed, the characteristics of people completing these documents, the choice of surrogate decision-maker for health care decisions, and with whom health care decisions were being discussed in a sample of 661 persons 65 years of age and older. Comparison between people with and without documents in place suggested that cognitive impairment, level of education, and age were related to preparation of documents. Women were typically chosen as surrogate decision-makers, except in a sample of unmarried men. Surprisingly, participants reported discussing preferences for health care decisions with someone other than their preferred surrogate. There appears to be a need to promote discussion of health care preferences between care-receivers and preferred surrogates.  相似文献
