Behavioral activation (BA), an effective treatment for depression, has recently been receiving attention as a possible intervention for PTSD. BA interventions could be particularly useful in treating underserved populations (i.e., individuals with lower socioeconomic status). A literature search was conducted, which identified seven outcome studies that examined the effectiveness of stand‐alone BA treatment for individuals with PTSD. All studies identified for this brief review demonstrated clinically significant reductions in PTSD symptoms using BA as an intervention. A meta‐analysis of these few studies revealed a nonsignificant effect (Cohen's d = 0.713, p = .512) despite reporting an average symptom reduction of 25.8%. Other studies utilizing BA treatment for PTSD do so in tandem with other interventions and were excluded from analysis. This brief review summarizes the literature on the use of BA as a stand‐alone treatment for PTSD and suggests that future research seek to confirm the usefulness of BA as a potential treatment modality for mental health‐care providers treating individuals with PTSD. 相似文献

Deferred imitation of object-related actions and generalization of imitation to similar but not identical tasks was assessed
in three human-reared (enculturated) chimpanzees, ranging in age from 5 to 9 years. Each ape displayed high levels of deferred
imitation and only slightly lower levels of generalization of imitation. The youngest two chimpanzees were more apt to generalize
the model's actions when they had displayed portions of the target behaviors at baseline, consistent with the idea that learning
is more likely to occur when working within the "zone of proximal development." We argue that generalization of imitation
is the best evidence to date of imitative learning in chimpanzees.

Three experiments explored the semantics of the mass-count distinction in young children and adults. In Experiments 1 and 2, the quantity judgments of participants provided evidence that some mass nouns refer to individuals, as such. Participants judged one large portion of stuff to be "more" than three tiny portions for substance-mass nouns (e.g. mustard, ketchup), but chose according to number for count nouns (e.g. shoes, candles) and object-mass nouns (e.g. furniture, jewelry). These results suggest that some mass nouns quantify over individuals, and that therefore reference to individuals does not distinguish count nouns from mass nouns. Thus, Experiments 1 and 2 failed to support the hypothesis that there exist one-to-one mappings between mass-count syntax and semantics for either adults or young children. In Experiment 3, it was found that for mass-count flexible terms (e.g. string, stone) participants based quantity judgments on number when the terms were used with count syntax, but on total amount of stuff when used with mass syntax. Apparently, the presence of discrete physical objects in a scene (e.g. stones) is not sufficient to permit quantity judgments based on number. It is proposed that object-mass nouns (e.g. furniture) can be used to refer to individuals due to lexically specified grammatical features that normally occur in count syntax. Also, we suggest that children learning language parse words that refer to individuals as count nouns unless given morpho-syntactic and referential evidence to the contrary, in which case object-mass nouns are acquired. 相似文献

Neurophysiological experiments with monkeys have demonstrated that working memory (WM) is associated with persistent neural
activity in multiple brain regions, such as the prefrontal cortex (PFC), the parietal cortex, and posterior unimodal association
areas. WM maintenance is believed to require the coordination of these brain regions, which do not function in isolation but,
rather, interact to maintain visual percepts that are no longer present in the environment. However, single-unit physiology
studies and traditional univariate analyses of functional brain imaging data cannot evaluate interactions between distant
brain regions, and so evidence of regional integration during WM maintenance is largely indirect. In this study, we utilized
a recently developed multivariate analysis method that allows us to explore functional connectivity between brain regions
during the distinct stages of a delayed face recognition task. To characterize the neural network mediating the on-line maintenance
of faces, the fusiform face area (FFA) was defined as a seed and was then used to generate whole-brain correlation maps. A
random effects analysis of the correlation data revealed a network of brain regions exhibiting significant correlations with
the FFA seed during the WM delay period. This maintenance network included the dorsolateral and ventrolateral PFC, the premotor
cortex, the intraparietal sulcus, the caudate nucleus, the thalamus, the hippocampus, and occipitotemporal regions. These
findings support the notion that the coordinated functional interaction between nodes of a widely distributed network underlies
the active maintenance of a perceptual representation. 相似文献

Two striking contrasts currently exist in the sentence processing literature. First, whereas adult readers rely heavily on lexical information in the generation of syntactic alternatives, adult listeners in world-situated eye-gaze studies appear to allow referential evidence to override strong countervailing lexical biases (Tanenhaus, Spivey-Knowlton, Eberhard, and Sedivy, 1995). Second, in contrast to adults, children in similar listening studies fail to use this referential information and appear to rely exclusively on verb biases or perhaps syntactically based parsing principles (Trueswell, Sekerina, Hill, and Logrip, 1999). We explore these contrasts by fully crossing verb bias and referential manipulations in a study using the eye-gaze listening technique with adults (Experiment 1) and five-year-olds (Experiment 2). Results indicate that adults combine lexical and referential information to determine syntactic choice. Children rely exclusively on verb bias in their ultimate interpretation. However, their eye movements reveal an emerging sensitivity to referential constraints. The observed changes in information use over ontogenetic time best support a constraint-based lexicalist account of parsing development, which posits that highly reliable cues to structure, like lexical biases, will emerge earlier during development and more robustly than less reliable cues. 相似文献

The aims of this study were to investigate exposure-based treatments for cynophobia (dog phobia) and to test a newly developed hybrid imaginal exposure treatment that we have named active imaginal exposure. The treatment introduces an in vivo coping component to imaginal exposure whereby the patient physically performs coping responses to an imagined feared stimulus. Eighty-two participants meeting DSM-IV criteria for specific phobia (animal subtype) were randomly assigned to one of three 30-min. treatments: (a) active-imaginal exposure (AI), (b) imaginal exposure alone (IE), or (c) graduated in vivo exposure (IV). Participants completed a behavioral approach test at pre, post, and four-week follow-up. Significant pre- to posttreatment improvement was observed in all three treatment conditions. Response rates at posttreatment were 51.9, 62.1, and 73.1% for the IE, AI, and IV groups respectively. Likewise, effect sizes at posttreatment were 0.76, 1.41, and 1.55 for the IE, AI, and IV groups respectively. Although in the predicted direction, the between group differences were not significant. A similar pattern of results was observed at follow-up. Further, safety behavior utilization during treatment was associated with less improvement--particularly in the two imaginal treatment conditions. Exposure treatments of dog phobia appear feasible and effective in reducing phobic fear and avoidance associated with dog phobia. Furthermore, preliminary evidence suggests that our active-imaginal exposure treatment may be a viable alternative to in vivo exposure. 相似文献

Using consensual qualitative research, the authors examined the treatment planning process of experienced counselors (N = 9). The data analysis resulted in 4 domains: assessment steps, clinical impressions, treatment factors, and treatment strategies. These domains describe the process used by experienced counselors in making clinical decisions and offer insight into the nature of clinical expertise and the need for further research on treatment planning. 相似文献

Since the global financial crisis of 2007/8, proliferating calls for a Keynesian Green New Deal have cast the publicly (and environmentally) minded state as a necessary driver of technological innovation and social transformation, while, vice versa, innovation has moved to political centre-stage. The history and genesis of this particular Green Keynesian paradigm illustrate that some of its most high-profile proponents selectively and problematically frame twentieth-century Keynesianism and the ‘public good’. It is important to examine critically the calls for an ‘entrepreneurial state’ in which Green Keynesian ideas are mobilized in support of an agenda for continued and accelerated development of commercially focused, privately developed green technologies. The entrepreneurial state represents a neoliberal re-appropriation of Green Keynesianism, where dominant financial actors (in Silicon Valley, as opposed to on Wall Street) are tapped as the visionaries who can and should set our collective innovation agenda. Although there is a need for large-scale, coordinated techno-social efforts to address climate change, supporting ‘green’ innovation cannot simply be framed as maximizing ‘innovation’ while taking the ‘state’ for granted. Instead, it must entail a careful assessment of the specific trajectories of innovation being enabled and the underlying socio-natures that they maintain and promote. Science and technology studies (STS)-informed analysis allows, and compels, asking how socio-technological innovation and their constitutive power relations are crucially interrelated, making the reshaping of the state—still the primary institution and system of social relations of collective governance—a core but neglected political, technological and ecological project of our time, with a key role for STS. 相似文献

The goal of this study was to identify diverse profiles of Asian American women's and men's adherence to values that are salient in Asian cultures (i.e., conformity to norms, family recognition through achievement, emotional self-control, collectivism, and humility). To this end, the authors conducted a latent profile analysis using the 5 subscales of the Asian American Values Scale-Multidimensional in a sample of 214 Asian Americans. The analysis uncovered a four-cluster solution. In general, Clusters 1 and 2 were characterized by relatively low and moderate levels of adherence to the 5 dimensions of cultural values, respectively. Cluster 3 was characterized by the highest level of adherence to the cultural value of family recognition through achievement, whereas Cluster 4 was typified by the highest levels of adherence to collectivism, emotional self-control, and humility. Clusters 3 and 4 were associated with higher levels of depressive symptoms than Cluster 1. Furthermore, Asian American women and Asian American men had lower odds of being in Cluster 4 and Cluster 3, respectively. These findings attest to the importance of identifying specific patterns of adherence to cultural values when examining the relationship between Asian Americans' cultural orientation and mental health status. 相似文献

Gene Heyman's Addiction: A Disorder of Choice (2009) advances the important, albeit controversial, view that addiction is not a chronic, relapsing brain disease, but instead is an example of typical everyday choice that is both voluntary and self‐destructive. This review highlights Heyman's arguments for conceptualizing addiction as choice and discusses the utility of the treatment implications that are derived from the melioration model in which Heyman frames addiction. Self‐control and behavioral economics are presented as additional complementary frameworks for understanding addiction as choice, from which pragmatic, evidence‐based treatments for addiction (e.g., contingency management) might more easily be derived. 相似文献
