The seven articles in this Special Section of the Journal of Psychopathology and Behavioral Assessment underscore the point that, at least in the psychopathy domain, parsimony is frequently an inaccurate scientific heuristic. These articles highlight the multidimensionality of youth psychopathy, suggesting that (a) the full constellation of psychopathy tends to outperform callous-unemotional traits alone in statistically predicting external criteria, (b) psychopathy subdimensions often interact statistically in predicting such criteria, and (c) psychopathy subdimensions often bear markedly different external correlates, including criminal offending, trait anxiety, and emotion processing. I offer five recommendations for future research on psychopathy and argue that that a full comprehension of this condition will require a better understanding of its subdimensions, and their interrelations, placement within the general personality domain, physiological correlates, and genetic and environmental underpinnings. 相似文献
Perfectionism is hypothesized to contribute to the etiology of anorexia nervosa (AN). However, there is little research regarding whether individuals with AN can be classified according to maladaptive (e.g., evaluative concerns) and adaptive (e.g., high personal standards) facets of perfectionism that predict distinct outcomes and might warrant different intervention approaches. In this study, a latent profile analysis was conducted using data from adults with AN (n?=?118). Frost Multidimensional Perfectionism Scale (Frost et al. Cognitive Therapy and Research, 14(5), 449–46, 1990) subscales were used to identify subgroups differing according to endorsed perfectionism features (e.g., adaptive and maladaptive perfectionism). Generalized linear models were used to compare subgroups on eating disorder and affective symptoms measured through questionnaire and ecological momentary assessment. Four subgroups were identified: (a) Low Perfectionism; (b) High Adaptive and Maladaptive Perfectionism; (c) Moderate Maladaptive Perfectionism; and (d) High Maladaptive Perfectionism. Subgroups differed on overall eating disorder symptoms (p?<?.001), purging (p?=?.005), restrictive eating (p?<?.001), and body checking (p?<?.001) frequency, depressive (p?<?.001) and anxiety (p?<?.001) symptoms, and negative (p?=?.001) and positive (p?<?.001) affect. The Low Perfectionism group displayed the most adaptive scores and the Moderate and High Maladaptive Perfectionism groups demonstrated the most elevated clinical symptoms. The High Adaptive and Maladaptive Perfectionism group demonstrated low affective disturbances, but elevated eating disorder symptoms. Results support the clinical significance of subtyping according to perfectionism dimensions in AN. Research is needed to determine if perfectionism subtyping can enhance individualized treatment targeting in AN. 相似文献
Understanding individual differences in cognitive performance is an important part of understanding how variations in underlying cognitive processes can result in variations in task performance. However, the exploration of individual differences in the components of the decision process—such as cognitive processing speed, response caution, and motor execution speed—in previous research has been limited. Here, we assess the heritability of the components of the decision process, with heritability having been a common aspect of individual differences research within other areas of cognition. Importantly, a limitation of previous work on cognitive heritability is the underlying assumption that variability in response times solely reflects variability in the speed of cognitive processing. This assumption has been problematic in other domains, due to the confounding effects of caution and motor execution speed on observed response times. We extend a cognitive model of decision‐making to account for relatedness structure in a twin study paradigm. This approach can separately quantify different contributions to the heritability of response time. Using data from the Human Connectome Project, we find strong evidence for the heritability of response caution, and more ambiguous evidence for the heritability of cognitive processing speed and motor execution speed. Our study suggests that the assumption made in previous studies—that the heritability of cognitive ability is based on cognitive processing speed—may be incorrect. More generally, our methodology provides a useful avenue for future research in complex data that aims to analyze cognitive traits across different sources of related data, whether the relation is between people, tasks, experimental phases, or methods of measurement. 相似文献
Procedural extinction is sometimes associated with a temporary increase in responding known as an extinction burst. Extinction bursts present unique challenges in the context of treating behavior targeted for reduction. The present study updates the prevalence of extinction bursts using a clinical sample (N = 108) receiving treatment for targeted behavior. The prevalence of extinction bursts in our sample (24%) was consistent with that in prior literature. The extinction-burst magnitude decreased across sessions after extinction was contacted during treatment, but this sample did not demonstrate decreased persistence or magnitude of extinction bursts across successive transitions from baseline to treatment. We also examined the prevalence and magnitude of extinction bursts based on the function and topography of targeted behavior and treatment components and found no consistent relation among these variables. These findings should lead clinicians to prepare for transient extinction bursts when implementing extinction-based treatment for challenging behavior. 相似文献
Globally, an estimated 79.5 million individuals have been displaced, nearly 40% of whom are children. Parenting interventions may have the potential to improve outcomes for displaced families. To investigate this, we conducted a systematic review to identify the types of caregiver or parenting interventions that have been evaluated among displaced families, to assess their efficacy across a range of contexts, and to describe their cultural and contextual adaptations. The review followed PRISMA guidelines. At stage one, all articles describing caregiver/parenting interventions for forcibly displaced families were included to provide a scoping review of the state of the literature. At stage two, only randomized controlled trials (RCTs) and quasi-experimental designs were included, allowing for quantitative analysis of program effects. A total of 30 articles (24 studies) were identified in stage one. 95.8% of these articles were published in the past 10 years. Of these, 14 articles (10 studies) used an RCT or quasi-experimental design to assess program efficacy or effectiveness. Relative to control groups, those assigned to caregiving programs showed significant, beneficial effects across the domains of parenting behaviors and attitudes, child psychosocial and developmental outcomes, and parent mental health. Cultural adaptations and recruitment and engagement strategies are described. The evidence base for caregiving programs for displaced families has expanded in recent years but remains limited. Caregiving/parenting programs show promise for reducing the negative effects of forced displacement on families, but future studies are needed to understand which programs show the greatest potential for scalability.

Theories of cognitive development have led to enduring and fierce arguments that have been long on rhetoric but short on evidence. Constructivist theory has roots in Piagetian notions of cognitive development as proceeding from self-directed action during infancy. Nativist theories subsequently became popular by producing claims of cognitive precocity, but left open many central questions concerning mechanisms of development. Now, a new view of constructivism is experiencing a renaissance, having achieved greater psychophysical, computational and neural plausibility. 相似文献
We examined the long‐term direct and indirect links between coparenting (conflict, communication, and shared decision‐making) and preschoolers' school readiness (math, literacy, and social skills). The study sample consisted of 5,650 children and their biological mothers and fathers who participated in the Early Childhood Longitudinal Study‐Birth Cohort. Using structural equation modeling and controlling for background characteristics, we found that our conceptual model of the pathways from coparenting to child outcomes is structurally the same for cohabiting and married families. Controlling for a host of background characteristics, we found that coparenting conflict and shared decision‐making were negatively and positively, respectively, linked to children's academic and social skills and co‐parental communication was indirectly linked to academic and social skills through maternal supportiveness. Coparenting conflict was also indirectly linked to children's social skills through maternal depressive symptoms. The overall findings suggest that for both cohabiting and married families, the context of conflicted coparenting may interfere with the development of children's social competencies and academic skills, whereas collaborative coparenting promotes children's school readiness because mothers are more responsive to their children's needs. These findings have implications for programs aimed at promoting positive family processes in cohabiting and married families. 相似文献
Using Tukey-Kramer versus the ANOVA F-test as the omnibus test of the Hayter-Fisher procedure for comparing all pairs of normally distributed means, when sample sizes are unequal, is investigated. Simulation results suggest that using Tukey-Kramer leads to as much or more any-pairs power compared to using the F-test for certain patterns of mean differences, and equivalent per-pair and all-pairs power for all cases. Furthermore, using Tukey-Kramer results in a consonant test procedure, where there cannot be disagreement between the results of the omnibus test and the subsequent pairwise tests. The results suggest that when sample sizes are unequal, Tukey-Kramer may be preferred over the F-test as the omnibus test for the Hayter-Fisher procedure. 相似文献
The self‐esteem movement has been around since the 1970s, and may have influenced how much value people place on self‐esteem. We predicted a negative relationship between age and the amount of value placed on self‐esteem boosts. We also investigated the correlates of liking versus wanting self‐esteem boosts (and other pleasant rewards) on depression. A nationally representative sample of American adults (N = 867) indicated how much they liked and wanted several pleasant rewards (i.e., sex, food, alcohol, money, friendship, self‐esteem boost). They also completed a standardized measure of depressive symptoms. As expected, there was a negative relationship between age and valuing self‐esteem boosts, sex, and alcohol. People with depressive symptoms wanted self‐esteem boosts, even though they did not like them very much. Similar effects were obtained for depressive symptoms and alcohol and friendship. This is the first research to show that self‐esteem boosts are more valued among a nationally representative sample of younger American adults. It also is the first research to explore the association between depression and the motivation to boost self‐esteem. People with depressive symptoms want self‐esteem, and may pursue it, but this pursuit may feel unrewarding because they do not derive pleasure from it. 相似文献
