Abstract

This study demonstrates that left and right unilateral facial contractions have similar effects on the expression of ethnic stereotypes as do negative and positive moods induced by more conventional means. Subjects who con tracted the left side of their face (negative mood inducer) were more likely to express negative stereotypes of ethnic groups than were subjects who contracted the right side of their face (positive mood inducer). This parallels previous findings obtained using two standard mood inductions: the Veltens mood induction procedure; and a musical mood induction procedure. Given that unilateral facial contractions manipulate mood without cognitive involvement, this mood induction may have advantages over previously used procedures, the effects of which are subject to cognitive mediation explanations. In addition, these results suggest that, at least for the expression of ethnic stereotypes, mood's influence on cognition does not depend on a cognitive component of mood induction.  相似文献

The use of empirical prior information about participants has been shown to substantially improve the efficiency of computerized adaptive tests (CATs) in educational settings. However, it is unclear how these results translate to clinical settings, where small item banks with highly informative polytomous items often lead to very short CATs. We explored the risks and rewards of using prior information in CAT in two simulation studies, rooted in applied clinical examples. In the first simulation, prior precision and bias in the prior location were manipulated independently. Our results show that a precise personalized prior can meaningfully increase CAT efficiency. However, this reward comes with the potential risk of overconfidence in wrong empirical information (i.e., using a precise severely biased prior), which can lead to unnecessarily long tests, or severely biased estimates. The latter risk can be mitigated by setting a minimum number of items that are to be administered during the CAT, or by setting a less precise prior; be it at the expense of canceling out any efficiency gains. The second simulation, with more realistic bias and precision combinations in the empirical prior, places the prevalence of the potential risks in context. With similar estimation bias, an empirical prior reduced CAT test length, compared to a standard normal prior, in 68% of cases, by a median of 20%; while test length increased in only 3% of cases. The use of prior information in CAT seems to be a feasible and simple method to reduce test burden for patients and clinical practitioners alike.  相似文献

In this article, I reply to the comments offered by R. Jay Wallace, Matthieu Queloz, and Claire Kirwin on my book, The Will to Nothingness. An Essay on Nietzsche's Genealogy of Morality (OUP, 2021). These comments and my replies cover central features of the book, including my analysis of ressentiment as an expression of the will to power; the concept of self-undermining functionality I introduce to make sense of Nietzsche's critique of the ascetic ideal; and my reasons for omitting to examine the “unconditional will to truth,” which he presents as the latest embodiment of this ideal.  相似文献

In this article, I describe how I encountered cybernetics and how it became an important part of my life. I begin with an account of my time at Brunel University and also describe how I came to work with Gordon Pask, one of the few intellectuals and researchers in the UK who styled themselves as cyberneticians. To enrich my story, I include an overview of the story of cybernetics as I perceive it. Given the importance I attach to cybernetics as an intellectual tool, I end with a plea for it to be included in all educational curricula.  相似文献

In this study, we introduce the construct of the suicidal narrative, a hypothetical personal narrative linked to imminent suicide, and explore its relationship to near‐term suicidal risk and the suicide crisis syndrome (SCS). Psychiatric outpatients (N = 289) were administered the Columbia Suicide‐Severity Rating Scale (C‐SSRS), Suicide Crisis Inventory (SCI), and Suicide Narrative Inventory (SNI), a novel instrument combining the documented risk factors of Thwarted Belongingness, Perceived Burdensomeness, Humiliation, Social Defeat, Goal Disengagement, and Goal Reengagement. Dimensional measures of past month, lifetime, and past suicidal phenomena, incorporating ideation and behavior, were calculated from the C‐SSRS. Structural equation modeling was used to explore the interaction among variables. Factor analysis of the SNI yielded two orthogonal factors, termed Interpersonal and Goal Orientation. The former factor was comprised of Perceived Burdensomeness, Social Defeat, Humiliation, and Thwarted Belongingness, the latter of Goal Disengagement and Goal Reengagement. The Interpersonal factor correlated with both SCS severity and suicidal phenomena in each time frame and the Goal Orientation factor with no other variable. As hypothesized, the proposed model was significant for the past month only. Our findings support the construct of the suicidal narrative and its function as a near‐term suicidal risk factor.  相似文献

Children who experience early adversity are at increased risk for developing psychopathology, and dysfunction of the hypothalamic pituitary adrenal (HPA) axis is a possible mechanism conferring this risk. This study sought to characterize the association between morning cortisol during different developmental periods and deficits in children's emotion regulation, a core feature of many psychological disorders. Morning cortisol was collected at two time points (i.e., during infancy, M = 13.0 months old, and during early childhood, M = 36.8 months old) from 120 children with histories of child protective services (CPS) involvement. Children completed a lab visit during early childhood (M = 38.6 months old) that involved an observational measure of anger regulation. Results showed that low morning cortisol during infancy, but not early childhood, predicted increased anger dysregulation during early childhood. These results highlight the importance of developmental timing in assessing the effects of HPA axis functioning and suggest that low cortisol during infancy is a risk factor for later emotion regulation difficulties.  相似文献

This study assessed secondborn adolescents' perceptions of changes in the allocation of family resources following their firstborn siblings' departure from home after high school, and whether perceived changes were related to changes over 1 year in secondborns' academic functioning. Participants were secondborn siblings (mean age = 16.58, SD = 0.91) from 115 families in which the older sibling had left the family home in the previous year. Allocation of resources was measured via coded qualitative interviews. Most (77%) secondborns reported increases in at least one type of family resource (i.e., parental companionship, attention, material goods), and many reported an increase in multiple types of resources in the year following their older sibling's departure. Consistent with resource dilution theory, perceptions of increases in fathers' companionship, fathers' attention, and mothers' companionship were related to improvements over time in secondborns' academic functioning.  相似文献
