Ecological momentary assessment (EMA) studies typically rely on arbitrary decision rules for identifying and excluding invalid responses from the data. In addition, most studies treat independent variables as separate from each other even if their combinations might have importance above the independent contribution of each. Our study aimed to conduct an exploratory latent profile analysis of EMA data to demonstrate an empirical method of identifying invalid responses, and to provide a preliminary investigation of mood profiles. We recruited 20 adolescents between the ages of 13–18 to complete 4 surveys about their internal states each day for 20 days. Participants provided responses on study smartphones using an Android app developed by the study team. Our profile analysis revealed 9 independent profiles. We determined that 3 of these profiles consisted of invalid responses because the integers provided by the participant were nearly invariant. The invalid responses comprised 24.9% of the sample. We also identified 6 valid profiles that were labeled: fatigued (8.7%), good mood/energetic (19.9%), angry/depressed (2.3%), good mood (37.1%), angry (5.7%), and depressed (1.4%). One important implication of the current study is that researchers and clinicians should screen electronic diary data, especially for invariant responding. In addition, it is important for clinicians to note that more than one internal state may drive the mood of an adolescent patient. 相似文献
In Experiment 1, rats choosing in an E maze preferred to release a rat standing in a pool of water to dry ground over a rat already standing on dry ground. Five additional experiments showed that the choosing rat’s preference for releasing the wet rat was maintained by two separable outcomes: (1) the social contact offered by the released rat and (2) the reinforcing value of proximity to a pool of water. These results call into question Sato et al.’s (Anim Cogn 18:1039–1047, 2015) claim to have demonstrated that a rat’s releasing of a wet rat to dry ground is empathically motivated. 相似文献
This study tests a group-based secular contemplative practice intervention, Cognitively-Based Compassion Training (CBCT), with parents of young children. We report on a randomized controlled preliminary efficacy study. Certified teachers administered CBCT for 20 hr across 8 to 10 weeks in two cohorts of parents with infants and young children. The intervention group was compared to a waitlist control group. Thirty-nine parents and their children, who ranged in age from 4 months to 5 years, were evaluated at pre- and postintervention (n = 25 intervention, n = 14 waitlist control) on hair cortisol concentration. Parents also completed self-administered questionnaires at both time points regarding demographics, physical symptoms of stress, parenting stress, self-compassion, and mindfulness. Children of parents in the CBCT group experienced significant decreases in cortisol at the postintervention assessment, as compared with the control group. However, parent cortisol and self-report measures did not significantly change other than a small effect on clinical levels of parenting stress. CBCT may be a positive new way to intervene with parents to lower infants’ and young children's cumulative physiological stress. 相似文献
Findings across a wide body of research suggest that media targeted at young audiences often portray characters according to stereotypical gender roles. Childhood is a particularly sensitive time in gender identity development, and logic from social cognitive theory suggests that repeatedly observing these stereotypes can have a lasting influence on young audiences’ worldview. Building on previous research investigating gender role displays in film content, and with the expectation that content creators use movie posters to convey a one-shot summary of films to audiences, we conducted a content analysis on the gendered power depictions of the main characters in movie posters of 152 popular U.S. animated children’s feature films produced over the last 80 years. Findings revealed that main characters were more likely to be male and that males were portrayed as more powerful. These results add to a growing, yet substantial, body of research illustrating the prevalence of stereotypical gender role portrayals across virtually every popular medium with which children come into contact. We discuss our results’ implications for potential short-term and long-term effects of exposure to films’ gender role stereotypes on young viewers’ real-life gender role expectations.
Corticosteroid receptors are critical for the maintenance of homeostasis after both psychological and physiological stress. To understand the different roles and interactions of the glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) during stress, it is necessary to dissect the role of corticosteroid signaling at both the system and sub-system level. A variety of GR transgenic mouse lines have recently been used to characterize the role of GR in the CNS as a whole and particularly in the forebrain. We will describe both the behavioral and cellular/molecular implications of disrupting GR function in these animal models and describe the implications of this data for our understanding of normal endocrine function and stress adaptation. MRs in tight epithelia have a long established role in sodium homeostasis. Recently however, evidence has suggested that MRs in the limbic brain also play an important role in psychological stress. Just as with GR, targeted mutations in MR induce a variety of behavioral changes associated with stress adaptation. In this review, we will discuss the implications of this work on MR. Finally, we will discuss the possible interaction between MR and GR and how future work using double mutants (through conventional means or virus based gene alteration) will be needed to more fully understand how signaling through these two steroid receptors provides the adaptive mechanisms to deal with a variety of stressors. 相似文献
Assessment of irrational beliefs by such measures as the Common Beliefs Survey III (CBS) has traditionally relied upon classical
test theory assumptions, in which the properties of specific test items are less important than the total test score as the
aggregate of all item responses. An alternative approach using item response theory (IRT) methodology allows one to specify
the parameters of difficulty and discrimination for each test item. Difficulty levels of CBS items range along a continuum of irrationality, the implied latent trait measured by responses to the questionnaire as a whole. We evaluated the CBS responses of 605 individuals
from clinical and college settings, drawing from current and archival data. The original Likert scale ratings were recoded
into dichotomous scores. Fourteen of the 54 items were highly or very highly discriminating in distinguishing respondents
with high and low irrationality levels. However, discriminating items exhibited a very narrow range of difficulty; most functioned
at a point a little above the halfway mark on the continuum of irrationality. Item characteristic curves and test information
curves were very similar for female (n = 424) and male (n = 179) respondents. We derived a 4-item screening test for irrationality from our IRT analyses of the 54 CBS items. Further
test development, focused on the selection and scaling of items with a much broader range of difficulty, would facilitate
evaluation of the hierarchical structure of irrational beliefs.

Borderline pathology of childhood (BPC) may be a precursor of personality disorders. There is a lack of data concerning outcome in adolescence. A group of 59 adolescents, who had been treated as children in a Child Psychiatry Day Hospital five to seven years earlier, was evaluated. Using the child version of the Retrospective Diagnostic Interview for Borderlines, 28 participants had been diagnosed with BPC while the remaining 31 participants who did not have a history of BPC served as the comparison group. The youth and their parents were given a battery of measures assessing current psychopathology and functional status. The group with a history of BPC was more likely than the comparison group to exhibit a combination of internalizing and externalizing behavior problems. Adolescents with a history of BPC were more impaired than the comparison group on a global measure of functional status. Compared to children with no history of BPC, children diagnosed with BPC are more likely to display poorer functioning as adolescents and continue to be at risk for psychopathology during adolescence. Future directions for research are discussed. 相似文献
There is mounting evidence that language comprehension involves the activation of mental imagery of the content of utterances ( Barsalou, 1999 ; Bergen, Chang, & Narayan, 2004 ; Bergen, Narayan, & Feldman, 2003 ; Narayan, Bergen, & Weinberg, 2004 ; Richardson, Spivey, McRae, & Barsalou, 2003 ; Stanfield & Zwaan, 2001 ; Zwaan, Stanfield, & Yaxley, 2002 ). This imagery can have motor or perceptual content. Three main questions about the process remain under‐explored, however. First, are lexical associations with perception or motion sufficient to yield mental simulation, or is the integration of lexical semantics into larger structures, like sentences, necessary? Second, what linguistic elements (e.g., verbs, nouns, etc.) trigger mental simulations? Third, how detailed are the visual simulations that are performed? A series of behavioral experiments address these questions, using a visual object categorization task to investigate whether up‐ or down‐related language selectively interferes with visual processing in the same part of the visual field (following Richardson et al., 2003 ). The results demonstrate that either subject nouns or main verbs can trigger visual imagery, but only when used in literal sentences about real space—metaphorical language does not yield significant effects—which implies that it is the comprehension of the sentence as a whole and not simply lexical associations that yields imagery effects. These studies also show that the evoked imagery contains detail as to the part of the visual field where the described scene would take place. 相似文献
We discuss some of the lessons the investigators learned during the development, implementation, and dissemination phases
of the National Arts and Youth Demonstration Project (NAYDP). The lessons learned are relevant to various groups involved
in large-scale, multi-site, community-based intervention studies: parents, youth, researchers, project staff, policy makers,
and funders. Specific lessons learned include: (1) how to engage the community; (2) methodological lessons, including cross-site
training and monitoring adherence to research protocol; (3) recruiting and sustaining involvement of parents and youth; (4)
program development; and (5) dissemination strategies. 相似文献
