In various research fields, biomarkers are now widely used as tools for assessing individual integrity. The recent advances in quantification methods for behavioral patterns, such as computerized video-tracking procedures, make them valuable biomarkers. However, the corollary of these novelties is that they remain relatively unknown and unused. In this study, we show that such tools can assess the validity of research methods, such as individual recognition. To demonstrate this, we employed, as a model, a marking method (passive integrated transponder [PIT] tagging) widely used in amphibians. Detailed visual observations and video-tracking methods were complementary in highlighting components at different behavioral scales: locomotion, feeding, and breeding. We illustrate the scientific and ethical adequacy of the targeted marking method but also suggest that more studies should integrate behavioral analyses. Such biomarkers are a powerful tool for assessing conservation concerns when other techniques cannot detect detrimental effects.  相似文献

In this study, 10 recent meta-analytic and systematic review studies were synthesized on the neurological underpinnings of stress and trauma with implications for the impact of parental post-traumatic stress disorder (PTSD) and resilience among military children. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) group guidelines and utilizing a validated quality assessment tool, this systematic review of reviews incorporated results from more than 35,971 individuals with stress exposures, effects, or disorders and healthy controls. This synthesis found support for important gene, physiology, and environment correlations and interactions that predict increased risk for stressful life events and PTSD, but not direct transmission, among military children. Future research is needed to determine if these constitute indirect pathways of intergenerational transmission in military children.  相似文献

ABSTRACT— Stigma is a risk factor for mental health problems, but few studies have considered how stigma leads to psychological distress. The present research examined whether specific emotion-regulation strategies account for the stigma-distress association. In an experience-sampling study, rumination and suppression occurred more on days when stigma-related stressors were reported than on days when these stressors were not reported, and rumination mediated the relationship between stigma-related stress and psychological distress. The effect of social support on distress was moderated by the concealability of the stigma: Lesbian, gay, and bisexual (LGB) respondents reported more isolation and less social support than African American respondents subsequent to experiencing stigma-related stressors, whereas African Americans reported greater social support than LGB participants. Social isolation mediated the stigma-distress association among LGB respondents. In a second experimental study, participants who ruminated following the recall of an autobiographical discrimination event exhibited prolonged distress on both implicit and explicit measures relative to participants who distracted themselves; this finding provides support for a causal role of rumination in the stigma-distress relationship.  相似文献

Interactive cognitive complexity theory suggests that simulation games are more effective than other instructional methods because they simultaneously engage trainees’ affective and cognitive processes ( Tennyson & Jorczak, 2008 ). Meta‐analytic techniques were used to examine the instructional effectiveness of computer‐based simulation games relative to a comparison group (k= 65, N= 6,476). Consistent with theory, posttraining self‐efficacy was 20% higher, declarative knowledge was 11% higher, procedural knowledge was 14% higher, and retention was 9% higher for trainees taught with simulation games, relative to a comparison group. However, the results provide strong evidence of publication bias in simulation games research. Characteristics of simulation games and the instructional context also moderated the effectiveness of simulation games. Trainees learned more, relative to a comparison group, when simulation games conveyed course material actively rather than passively, trainees could access the simulation game as many times as desired, and the simulation game was a supplement to other instructional methods rather than stand‐alone instruction. However, trainees learned less from simulation games than comparison instructional methods when the instruction the comparison group received as a substitute for the simulation game actively engaged them in the learning experience.  相似文献

Background and objectives: Although intimate partner violence (IPV) has demonstrated strong associations with anxiety and posttraumatic stress, these constructs have rarely been examined simultaneously in IPV research. Gaps in knowledge remain as to their differential associations to substance use problems among IPV-victimized women. Design: A sample of 143 community women self-reported on their current IPV victimization, mental health and substance use problems. Method: Hierarchical entry multiple regressions were used to test for the direct and indirect effects of psychological, physical, and sexual IPV to alcohol and drug problems through anxiety and posttraumatic stress. Results: Higher anxiety symptom severity and higher physical IPV severity were associated with greater alcohol and drug problems. Higher posttraumatic stress symptom severity was associated with greater alcohol and drug problems. Mediation analyses indicated (i) significant indirect pathways of IPV types to alcohol problems through posttraumatic stress symptom severity controlling for anxiety symptom severity and (ii) significant indirect pathways of IPV types to drug problems through anxiety symptom severity controlling for posttraumatic stress symptom severity. Conclusions: In examining the indirect pathways of psychological, physical, and sexual IPV to substance use problems this study highlights that anxiety and posttraumatic stress symptom severity have unique effects on alcohol and drug problems among IPV-victimized women.  相似文献

Competition strongly affects individual effort and performance for both individuals and groups. Especially in work settings, these effort gains might come at the cost of individual well‐being. The present study tested whether competition increases both effort (as indicated by task performance) and stress (in terms of cardiovascular reactivity and affective response), and whether this effect is further qualified by the type of competition (interindividual vs. intergroup), using a cognitive computer‐based task and a 2 (Group: Yes, No) × 2 (Competition: Yes, No) × 2 (Gender) factorial design (N= 147). All participants either worked as a representative of a group or as an individual, and were offered performance‐related incentives distributed in a lottery. In the competition conditions, participants were informed that they competed with someone else, and that only the winning person/team would take part in the lottery. Consistent with expectations, competition increased both individual effort and cardiovascular reactivity compared to non‐competitive work. Moreover, for female participants, intergroup competition triggered increased effort and more positive affect than interindividual competition. Aside from documenting costly side‐effects of competition in terms of stress, this study provides evidence for a stress‐related explanation of effort gains during intergroup competition as compared to interindividual competition.  相似文献

Two studies investigated the utility of indirect scaling methods, based on graded pair comparisons, for the testing of quantitative emotion theories. In Study 1, we measured the intensity of relief and disappointment caused by lottery outcomes, and in Study 2, the intensity of disgust evoked by pictures, using both direct intensity ratings and graded pair comparisons. The stimuli were systematically constructed to reflect variables expected to influence the intensity of the emotions according to theoretical models of relief/disappointment and disgust, respectively. Two probabilistic scaling methods were used to estimate scale values from the pair comparison judgements: Additive functional measurement (AFM) and maximum likelihood difference scaling (MLDS). The emotion models were fitted to the direct and indirect intensity measurements using nonlinear regression (Study 1) and analysis of variance (Study 2). Both studies found substantially improved fits of the emotion models for the indirectly determined emotion intensities, with their advantage being evident particularly at the level of individual participants. The results suggest that indirect scaling methods yield more precise measurements of emotion intensity than rating scales and thereby provide stronger tests of emotion theories in general and quantitative emotion theories in particular.  相似文献

Sixty hooded Long‐Evans rats were assigned to one of three conditions: isolation‐rearing (from 14–30 days of age), brief isolation (from 28–30 days of age), and normal (no isolation). From day 14 to day 21, the isolation‐reared animals were maintained in an incubator set at 35°C to prevent hypothermia and were separated from each other by Plexiglas. They learned to nourish themselves by lapping milk that continuously flowed down one side of the enclosure. Thereafter, they were housed in standard hanging wire cages. Unlike previous studies of isolation at this age, there were no significant weight differences between the isolation‐reared group and the two control groups. At 30 days of age, the three groups were compared on fighting (serious and play), nonagonistic social behaviors (following and crawling under), and exploratory behavior (open‐field ambulation). The isolation‐reared group was significantly different from the normal group on all measures (isolates were higher on all measures except exploration). The isolation‐reared animals showed significantly more serious fighting (aggression) than the brief isolation animals, whereas these two groups did not differ on other behaviors. This methodology allows for the study of isolation‐rearing without the nutritional confounds found in previous research and shows an effect on aggression that is not accounted for by recent isolation.

For more than sixty years, the leaderless group discussion (LGD) has been commonly used to assess leadership emergence and potential. This research focuses on individual differences as predictors of leader emergence in LGDs. Meta-analytic methods allowed us to combine and compare results from 45 studies, producing 196 effect sizes, and make statistically guided decisions about the strength of relationships between individual difference and personality variables and leadership emergence in LGDs. Consistent with more general research on leader emergence and effectiveness, we found a number of individual differences predictive of leader emergence in LGDs, most notably extraversion and authoritarian personality. This research augments previous meta-analytic research on personality and leadership with a focus specifically on the leaderless group discussion.  相似文献

The distribution of the product has several useful applications. One of these applications is its use to form confidence intervals for the indirect effect as the product of 2 regression coefficients. The purpose of this article is to investigate how the moments of the distribution of the product explain normal theory mediation confidence interval coverage and imbalance. Values of the critical ratio for each random variable are used to demonstrate how the moments of the distribution of the product change across values of the critical ratio observed in research studies. Results of the simulation study showed that as skewness in absolute value increases, coverage decreases. And as skewness in absolute value and kurtosis increases, imbalance increases. The difference between testing the significance of the indirect effect using the normal theory versus the asymmetric distribution of the product is further illustrated with a real data example. This article is the first study to show the direct link between the distribution of the product and indirect effect confidence intervals and clarifies the results of previous simulation studies by showing why normal theory confidence intervals for indirect effects are often less accurate than those obtained from the asymmetric distribution of the product or from resampling methods.  相似文献

This study of 137 helicopter pilot trainees investigated individual strategies used to obtain performance feedback during two consecutive phases of their training. Individual and situational factors cited in previous research were investigated as predictors of two feedback seeking behaviors: eliciting (asking directly for feedback) and monitoring (using indirect techniques, such as observing, to gain additional feedback). Both individual and situational factors were significant predictors of feedback seeking behaviors. Feedback seeking costs and the student pilots'external propensity (an individual difference measure assessing their desire for external feedback) were found to be the most consistent predictors of feedback eliciting and monitoring, both within and across the two training phases. In addition, the results point to higher feedback eliciting when performance was rated as low. The implications of this research are discussed, especially with respect to training.  相似文献

This study used qualitative research methods to investigate the sexual socialization experiences of young Asian American women, a group often overlooked in psychological research on sexuality. Focus group interviews were conducted with 30 ethnically diverse young Asian American women to explore their perceptions and interpretations of the direct and indirect sexual communication they received from parents during adolescence. Interviews were analyzed using open and focused coding techniques based on principles of grounded theory. Although most participants initially reported that sexuality was a closed or taboo topic of discussion in their family, they described several indirect, implicit, and nonverbal strategies their parents used to clearly convey their sexual attitudes and expectations, most of which were restrictive in nature. Women interpreted parents' silence and restrictiveness about sexuality as tied to their upbringing and cultural heritage and as a feature characterizing Asian parents more broadly.  相似文献

A number of different toilet training methods have recently been described. Ellis' (1963) model of toilet training is used to provide a simple basis for classifying these methods. Two main differences, timing versus regular potting, and intensive individual training versus group training are distinguished. Three toilet training programmes (intensive individual, regular potting; intensive individual, timing; group training, regular potting) are compared with five severely or profoundly mentally retarded children for each method. It is concluded that intensive individual training is more cost-effective than group training and that, although there is no significant difference between the intensive individual regular potting and timing methods, the former is the method of choice as it is slightly less complex. Various practical and theoretical issues arising from these toilet training programmes are discussed, including the need for more detailed study of bladder function and other factors related to the development of continence in such children.  相似文献
