The ability to perform multiple tasks simultaneously has become increasingly important as technologies such as cell phones and portable music players have become more common. In the current study, we examined dual-task costs in older and younger adults using a simulated street crossing task constructed in an immersive virtual environment with an integrated treadmill so that participants could walk as they would in the real world. Participants were asked to cross simulated streets of varying difficulty while either undistracted, listening to music, or conversing on a cell phone. Older adults were more vulnerable to dual-task impairments than younger adults when the crossing task was difficult; dual-task costs were largely absent in the younger adult group. Performance costs in older adults were primarily reflected in timeout rates. When conversing on a cell phone, older adults were less likely to complete their crossing compared with when listening to music or undistracted. Analysis of time spent next to the street prior to each crossing, where participants were presumably analyzing traffic patterns and making decisions regarding when to cross, revealed that older adults took longer than younger adults to initiate their crossing, and that this difference was exacerbated during cell phone conversation, suggesting impairments in cognitive planning processes. Our data suggest that multitasking costs may be particularly dangerous for older adults even during everyday activities such as crossing the street. 相似文献

Others’ choices that turn out badly often elicit schadenfreude; that is, feelings of malicious joy about the misfortunes of others. We examine the impact of experiencing schadenfreude when choosing between conventional and unconventional options. Results show that individuals are relatively more likely to choose compromise options and safe options when experiencing schadenfreude, in comparison to happiness and to sadness. In support of an affect-as-information mechanism underlying this effect, the influence of schadenfreude on choice is limited to situations in which decision-makers are unaware of the source of their affect. Our last study demonstrates that individuals interpret schadenfreude as information regarding which option they should choose: its experience heightens anticipation of unfavorable outcomes of their own choices. We end with a discussion of the theoretical and organizational implications of our research. 相似文献

How is attention guided by past experience? In visual search, numerous studies have shown that recent trials influence responses to the current trial. Repeating features such as color, shape, or location of a target facilitates performance. Here we examine whether recent experience also modulates a more abstract dimension of attentional control, object-based and location-based control. Participants performed a cued target discrimination task with stimuli presented on 2 rectangles. Response times to targets appearing in an uncued location on a cued rectangle were faster than to targets on the uncued rectangle, demonstrating an object-based attentional benefit. We investigated the object-based benefit on the current trial contingent on the cue-target relationship on the previous trial. The object-based benefit was significant only when the cued object contained the target on the previous trial, not when the uncued object contained the target. This effect of recent experience was not due to either the repetition of spatial cue-target location or the repetition of the response, but to adaptation to contingencies in the environment. Our results suggest a unifying view of attentional control that spans the concrete dimensions of control (e.g., determining the relative importance of red vs. blue) to the abstract (determining the relative importance of objects vs. locations in space). Attention closely tracks the short time scale structure of the environment and automatically adapts to optimize performance to this structure. 相似文献

Memory for related but unpracticed aspects of an event can be impaired by selectively retrieving parts of the same event. This occurs when selective retrieval [within‐individual retrieval‐induced forgetting (WI‐RIF)] is undertaken by individuals and has been extended to social contexts—RIF can be produced in listeners [socially shared retrieval‐induced forgetting (SS‐RIF)] by a speaker's selective recounting. The effects of post‐traumatic stress disorder (PTSD) on WI‐RIF and SS‐RIF were examined by two experiments. In Experiment 1, combat veterans (with or without PTSD) and non‐veteran dyads participated in a RIF paired‐associates paradigm adapted for combat‐related stimuli. WI‐RIF and SS‐RIF occurred for combat‐related and neutral pairs regardless of group. However, greater WI‐RIF and SS‐RIF for combat‐related words were shown by individuals with PTSD. These findings were replicated by Experiment 2, in which either a combat‐related or neutral story was learned by participants, and selective retrieval was embedded in a conversation. That the selective retrieval of trauma‐related stimuli leads to enhancement of induced forgetting for individuals with PTSD under certain conditions is suggested by these data.

Propelled from the inner circle after publishing The Trauma of Birth (1924), Otto Rank jettisoned Freud's science of knowing because it denied the intelligence of the emotions. Transforming therapy from knowing to being-in-relationship, Rank invented modern object-relations theory, which advocates continual learning, unlearning and relearning: that is, cutting the chains that bind us to the past. Separating, no matter how anxiety-provoking, from outworn phases of life, including previously taken-for-granted ideologies and internalized others, is essential for self-leadership. In 1926, Rank coined the terms “here-and-now” and “pre-Oedipal.” By 1926, Rank had formulated a model of “creative willing”—self-leadership infused with the intelligence of the emotions—as the optimal way of being-in-relationship with others. 相似文献

In recent years, new sequencing technologies known as next generation sequencing (NGS) have provided scientists the ability to rapidly sequence all known coding as well as non-coding sequences in the human genome. As the two emerging approaches, whole exome (WES) and whole genome (WGS) sequencing, have started to be integrated in the clinical arena, we sought to survey health care professionals who are likely to be involved in the implementation process now and/or in the future (e.g., genetic counselors, geneticists and nurse practitioners). Two hundred twenty-one genetic counselors— one third of whom currently offer WES/WGS—participated in an anonymous online survey. The aims of the survey were first, to identify barriers to the implementation of WES/WGS, as perceived by survey participants; second, to provide the first systematic report of current practices regarding the integration of WES/WGS in clinic and/or research across the US and Canada and to illuminate the roles and challenges of genetic counselors participating in this process; and third to evaluate the impact of WES/WGS on patient care. Our results showed that genetic counseling practices with respect to WES/WGS are consistent with the criteria set forth in the ACMG 2012 policy statement, which highlights indications for testing, reporting, and pre/post test considerations. Our respondents described challenges related to offering WES/WGS, which included billing issues, the duration and content of the consent process, result interpretation and disclosure of incidental findings and variants of unknown significance. In addition, respondents indicated that specialty area (i.e., prenatal and cancer), lack of clinical utility of WES/WGS and concerns about interpretation of test results were factors that prevented them from offering this technology to patients. Finally, study participants identified the aspects of their professional training which have been most beneficial in aiding with the integration of WES/WGS into the clinical setting (molecular/clinical genetics, counseling and bioethics) and suggested that counseling aids (to assist them when explaining aspects of these tests to patients) and webinars focused on WES/WGS (for genetic counselors and other health care professionals) would be useful educational tools. Future research should permit us to further enhance our knowledge of pitfalls and benefits associated with the introduction of these powerful technologies in patient care and to further explore the roles and opportunities for genetic counselors in this rapidly evolving field. 相似文献

The purpose of this study is to provide normative data for the sound effect sequences of the Braverman-Chevigny Auditory Projective Test. The test was administered to 149 college undergraduates in a group setting, who were asked to compose stories to the seven sound sequences. Stories were coded in terms of tone, outcome, number of characters, theme, and identification of “hero.” The stories were predominantly negative in tone, with outcomes generally neutral or unsuccessful. Interscorer reliabilities were all significant beyond the .001 level. 相似文献

Eighteen Ss listened to neutral and emotional passages recorded by 22 speakers who had taken the Eysenck Personality Inventory. The estimates of extraversion arrived at by the 18 listener-judges did not correlate significantly with the EPI measure of extraversion. Despite this lack of criterion validity, some voices were clearly and reliably rated as more introverted or extraverted than others. The judges' own degree of extraversion was not a significant factor in the judgments. 相似文献
