It has been shown that stress affects episodic memory in general, but knowledge about stress effects on memory control processes such as directed forgetting is sparse. Whereas in previous studies item-method directed forgetting was found to be altered in post-traumatic stress disorder patients and abolished for highly arousing negative pictorial stimuli in students, no study so far has investigated the effects of experimentally induced psycho-social stress on this task or examined the role of positive picture stimuli. In the present study, 41 participants performed an item-method directed forgetting experiment while being exposed either to a psychosocial laboratory stressor, the Trier Social Stress Test (TSST), or a cognitively challenging but non-stressful control condition. Neutral and positive pictures were presented as stimuli. As predicted, salivary cortisol level as a biological marker of the human stress response increased only in the TSST group. Still, both groups showed directed forgetting. However, emotional content of the employed stimuli affected memory control: Directed forgetting was intact for neutral pictures whereas it was attenuated for positive ones. This attenuation was primarily due to selective rehearsal improving discrimination accuracy for neutral, but not positive, to-be-remembered items. Results suggest that acute experimentally induced stress does not alter item-method directed forgetting while emotional stimulus content does. 相似文献

With the expansion of genomic-based clinical applications, it is important to consider the potential impact of this information
particularly in terms of how it may be interpreted and applied to personal perceptions of health. As an initial step to exploring
this question, we conducted a study to gain insight into potential psychosocial and health motivations for, as well as impact
associated with, undergoing testing and disclosure of individual “variomes” (catalogue of genetic variations). To enable the
collection of fully informed opinions, 14 participants with advanced training in genetics underwent whole-genome profiling
and received individual reports of estimated genomic ancestry, genotype data and reported disease associations. Emotional,
cognitive and health behavioral impact was assessed through one-on-one interviews and questionnaires administered pre-testing
and 1-week and 3-months post-testing. Notwithstanding the educational and professional bias of our study population, the results
identify several areas of research for consideration within additional populations. With the development of new and less costly
approaches to genome risk profiling, now available for purchase direct-to-consumers, it is essential that genome science research
be conducted in parallel with studies assessing the societal and policy implications of genome information for personal use. 相似文献

Attentional capture can be contingent on attentional control settings (ACSs), such that peripheral cues influence processing for a subsequent target only when they share a critical feature with the target. Our previous demonstration that two ACSs from within the same feature category can be maintained simultaneously allows us to investigate the processing stage at which such ACSs are implemented. We compared the relative efficacy of ACSs from two different feature categories (shape and color) that are associated with different levels within the visual processing hierarchy. Participants were instructed to respond to one of two colors at one location and one of two shapes at another location, while ignoring the nontarget color and shape. We observed that spatial capture was modulated by whether the cues fit an ACS, with slightly greater contingent capture effects for ACSs defined by color than by shape. Thus, two ACSs from different feature sets (color and shape) can be maintained in parallel, although effectiveness of the control set varied with the type of feature. 相似文献

In this quasi-experimental study, we examine the alignment of a job redesign initiative with leadership training aimed at increasing supervisors’ opportunities for providing support to employees. In addition, we examine intervention-mediated effects on climate for innovation through increases in perceived supervisor support. To test the hypothesized process, we used employee ratings (N = 524) of perceived supervisor support and climate for innovation collected at three time points over 2 years in the home help services in seven Swedish municipalities. Results of latent growth curve analyses showed that employees in the intervention group had a stronger and positive slope of perceived supervisor support relative to the comparison group. Further, the growth trajectories of perceived supervisor support were positively associated with climate for innovation at the 24-month follow-up. The study contributes to the human resource management literature by showing that alignment of employment practices such as training with work practices such as job redesign may be a promising strategy for achieving positive outcomes at multiple levels in organizations. 相似文献

In this study, we investigated how the birth of a very low birth weight preterm (VLBW) infant influences the mother–infant interaction at 3 months. We also focused on the impact of the infant's neurobiological risk and maternal anxiety, and their interaction. The comparison of the VLBW preterm sample (n = 79) with an external full‐term sample (n = 35) showed mother–infant interactions of the families with the preterm infant to be more vocally responsive during the interaction, but less facially responsive during the interaction. Additionally, higher levels of maternal anxiety were associated with preterm infants being less facially responsive in interaction with their mother. While neurobiological risk of the infant played a part in this association, with higher risk infants also being less facially responsive, the relationship with maternal anxiety and the mother–child interaction was stronger. How these findings may influence therapeutic interventions is discussed. 相似文献

Two experiments were conducted to assess whether responses to helpers who used insensitive emotional support vary as a function
of the interaction between sex of participant and helper. We hypothesized that women would evaluate an insensitive female
helper and her behavior more negatively than they would an insensitive male helper. In Experiment 1, participants (N = 137) read conversations in which male or female helpers sought to comfort emotionally distressed friends. In Experiment
2, participants (N = 87) engaged in face-to-face interactions in which they were comforted by either a male or female helper who used insensitive
comforting messages. Overall, the results imply that women with deficient emotional support skills may be at high risk of
rejection by same-sex peers.

We conducted two experiments examining children's and adults' gaze behavior when processing faces analytically (focusing on a single feature) or holistically (comparing the overall similarity of the faces). Children 6-8 and 9-10 years of age and adults were instructed to assign schematically drawn faces in Experiment 1 and photos of real faces in Experiment 2 to two categories. The categories were constructed so as to allow either an analytical or holistic categorization of the faces. During all trials, gaze behavior was recorded from stimulus onset until reaction. The location and duration of the fixations used were analyzed. Whereas the holistic processors fixated the whole area of the eyes and nose most and longest independently of age, analytical processors showed a more feature-specific gaze behavior, focusing their fixations upon the particular feature used for subsequent processing. Thus, differences in analytical and holistic face processing can be detected early in gaze behavior-that is, at the visual encoding stage. 相似文献

The present study used a chimeric stimuli task to assess the magnitude of the left-hemispace bias in children with congenital unilateral brain damage (n = 46) as compared to typically developing matched controls (n = 46). As would be expected, controls exhibited a significant left-hemispace bias. In the presence of left hemisphere (LH) damage, the left-hemispace preference was found to be present, but attenuated, whereas right hemisphere (RH) damage resulted in a less lateralized process. Examination of lesion severity revealed that large lesions in the RH were associated with a reversal of the typical left-hemispace bias, while small lesions resulted in a left bias approximating that of controls. In contrast, the left-hemispace preference in children with LH damage was similar across lesion size. We conclude that damage to either hemisphere early in brain development may alter hemispheric preference for processing of nonverbal stimuli, and that at least in the case of RH damage, alteration of the normal perceptual asymmetry may depend on the interaction between lesion side and severity. 相似文献
