Exposure to a repeating sequence of target stimuli in a speeded localization task can support both priming of sequence-consistent responses and recognition of sequence components. In 3 experiments with both deterministic and probabilistic sequences, the authors used a novel procedure in which measures or priming and recognition were taken concurrently and asked whether these measures can be dissociated. In all of these experiments, both measures were above chance at the group level and no evidence of dissociation was found. Item-level analyses of the data in Experiment 3 did reveal dissociations in that (a) recognition judgments were affected by response speed independently of old-new status and (b) items that were not discriminated in recognition nonetheless showed priming. However, the authors show that these data, together with the group-level results, are compatible with a formal model in which priming and recognition are based on a single common memory variable. 相似文献

Motion onset captures attention 总被引:4,自引:0,他引:4
Although visual motion may seem salient, motion per se does not automatically attract attention. We show here, however, that the onset of motion does indeed attract attention. In three experiments, subjects identified target letters in displays that contained targets and distractors. There was no advantage for moving letters among static ones, but there was an advantage for objects that had recently started to move despite the fact that the motion was uninformative. If some additional time was allowed to elapse after motion onset, inhibition of return slowed responding to the item that had started to move—a further sign that the motion onset had captured attention. Finally, detection of target letters was found to be independent of the number of distractors in the display if the target had undergone motion onset, also indicative of attentional capture. We discuss the adaptive significance of sensitivity to onsets in the presence of a relative insensitivity to ongoing motion. 相似文献

To address the lack of a simple and standardized instrument to assess overall illness severity of Tourette's disorder (TD), the authors developed and tested a 15-item scale to measure a broad range of common symptoms including tics, inattention, hyperactivity, obsessions, compulsions, aggression, and emotional symptoms. Independent investigators used the 15-item Tourette's Disorder Scale (TODS) to assess 60 TD patients who were taking part in a double-blind placebo-controlled multicenter 8-week treatment study. Interrater reliability, internal consistency, convergent and discriminant validity, and sensitivity to change were examined. The TODS was associated with good interrater reliability, excellent internal consistency, and favorable levels of validity and sensitivity to change. Individual TODS items showed good convergent and discriminant validity against other measures. The TODS is a simple, efficient way for clinicians and parents to rate the severity of multiple symptoms commonly found in patients with Tourette's disorder. 相似文献

Finding a job has become a critical challenge to many youth. Immigrant youth, who have been a key part of the global migrants, are particularly vulnerable when entering the job market of the host country due to various structural barriers. However, in both public policy discourse and research, their labour market experience tends to be overlooked. In this paper, we report the employment experience of recently arrived immigrant youth based on an analysis of the LSIC and findings of in-depth interviews of 82 immigrant youth in four cities in Canada. Our results reveal that recently arrived immigrant youth tend to work in lower-skilled employment, experience significant delays in finding employment, have difficulties with foreign credential recognition, and have fewer means to access to job markets. 相似文献

Personality traits predict substance use in adolescence, but less is known about prospective substance use in middle age and beyond. Moreover, there is growing interest in how personality change and the multiplicative effects among personality traits relate to substance use. Participants included approximately 4000 adults aged 25-74 who participated in two waves of the Midlife in the US (MIDUS) study. Higher levels of neuroticism, extraversion, openness, and lower levels of conscientiousness and agreeableness predicted longitudinal substance use. Increases in neuroticism and openness predicted increased substance use while increases in conscientiousness and agreeableness predicted decreased substance use. Higher levels of conscientiousness moderated two of the other trait main effects. Personality, trait change, and interactions among traits reliably forecasted 10-year substance-use behaviors. 相似文献

As newborn screening (NBS) technology expands, genetic counselors will become more involved in counseling for NBS results, including those potentially generated from whole exome sequencing (WES) and eventually whole genome sequencing (WGS). Members of the National Society of Genetic Counselors (NSGC) responded to an online survey (n?=?208) regarding genomic counseling in the context of NBS. The majority of participants (82.1 %) did not feel prepared to counsel for WGS results from NBS. Counselors with previous WES/WGS counseling experience felt more prepared (p?=?0.005) to counsel for WGS results from NBS than those without WES/WGS experience. Overall, counselors expressed ethical and practical concerns regarding WGS in NBS, as well as a need for additional training regarding this application of the technology before it is implemented. Based on the results of this study, genetic counselors voice caution to the larger genetics community regarding expansion of NBS to incorporate genomic sequencing and advocate for additional education prior to initiating WGS into NBS. 相似文献

The past two decades have seen a tremendous surge in scientific interest in the extent to which certain types of training—be it aerobic, athletic, musical, video game, or brain trainer—can result in general enhancements in cognitive function. While there are certainly active debates regarding the results in these domains, what is perhaps more pressing is the fact that key aspects of methodology remain unsettled. Here we discuss a few of these areas including expectation effects, test–retest effects, the size of the cognitive test battery, the selection of control groups, group assignment methods, difficulties in comparing results across studies, and in interpreting null results. Specifically, our goal is to highlight points of contention as well as areas where the most commonly utilized methods could be improved upon. Furthermore, because each of the sub-areas above (aerobic training through brain training) share strong similarities in goal, theoretical framework, and experimental approach, we seek to discuss these issues from a general perspective that considers each as members of the same broad “training” domain. 相似文献
