In this paper we consider two problems concerning human psychophysical discriminability of variable interval nerve action potential patterns. The first question asks which of two possible alternatives-additional sample size or elongation of duration-is responsible for the improvement in performance as the number of pulses in a stimulus train increases. Our data strongly indicated that the answer to this question is increased sample size. The second question concerns what effect, if any, parallel rather than serial presentation of the two alternatives in a forced choice psychophysical test will have on the function relating interpulse interval and discriminability. The answer to this question appears to be that other than a slight elevation of the absolute levels no changes in the general form of the response is produced. 相似文献

The impact of event vividness,event severity,and prior paranormal belief on attributions towards a depicted remarkable coincidence experience: Two studies examining the misattribution hypothesis 下载免费PDF全文

Two studies examine the impact event vividness, event severity, and prior paranormal belief has on causal attributions for a depicted remarkable coincidence experience. In Study 1, respondents (n = 179) read a hypothetical vignette in which a fictional character accurately predicts a plane crash 1 day before it occurs. The crash was described in either vivid or pallid terms with the final outcome being either severe (fatal) or non‐severe (non‐fatal). Respondents completed 29 causal attribution items, one attribution confidence item, nine scenario perception items, a popular paranormal belief scale, and a standard demographics questionnaire. Principal axis factoring reduced the 29 attribution items to four attribution factors which were then subjected to a 2 (event vividness) × 2 (event severity) × 2 (paranormal belief) MANCOVA controlling for respondent gender. As expected, paranormal believers attributed the accurate crash prediction less to coincidence and more to both paranormal and transcendental knowing than did paranormal sceptics. Furthermore, paranormal (psychokinesis) believers deemed the prediction more reflective of paranormal knowing to both (1) a vivid/non‐fatal and (2) a pallid/fatal crash depiction. Vividness, severity, and paranormal belief types had no impact on attribution confidence. In Study 2, respondents (also n = 179) generated data that were a moderately good fit to the previous factor structure and replicated several differences across attributional pairings albeit for paranormal non‐believers only. Corresponding effects for event severity and paranormal belief were not replicated. Findings are discussed in terms of their support for the paranormal misattribution hypothesis and the impact of availability biases in the form of both vividness and severity effects. Methodological issues and future research ideas are also discussed. 相似文献

Repetitive transcranial magnetic stimulation (rTMS) is increasingly used as a therapeutic intervention for neuropsychiatric illnesses and has demonstrated efficacy for treatment of major depression. However, an unresolved question is whether a course of rTMS treatment results in effects on cognitive functioning. In this systematic review and meta-analysis we aimed to quantitatively determine whether a course of rTMS has cognitive enhancing effects. We examined cognitive outcomes from randomised, sham-controlled studies conducted in patients with neuropsychiatric conditions where rTMS was administered to the dorsolateral prefrontal cortex (DLPFC) across repeated sessions, searched from PubMed/MEDLINE and other databases up until October 2015. Thirty studies met our inclusion criteria. Cognitive outcomes were pooled and examined across the following domains: Global cognitive function, executive function, attention, working memory, processing speed, visual memory, verbal memory and visuospatial ability. Active rTMS treatment was unassociated with generalised gains across the majority of domains of cognitive functioning examined. Secondary analyses revealed a moderate sized positive effect for improved working memory in a small number of studies in patients with schizophrenia (k = 3, g = 0.507, 95 % CI = [0.183–0.831], p < .01). Therapeutic rTMS when administered to the DLPFC in patients with neuropsychiatric conditions does not result in robust cognitive enhancing effects. 相似文献

This study examines the relationships between coping responses and organizational outcomes for career‐plateaued and nonplateaued employees. The objective was to determine the efficacy of common coping responses suggested for plateaued employees. Positive activities, such as expanding job assignments, mentoring, functional or technical career paths, and projects or teams, were associated with more positive attitudes and higher perceived performance among plateaued employees. Among nonplateaued employees, there were no significant relationships found. Negative denial responses, such as blaming the supervisor or organization for the plateau, reporting intentions to leave, and use of alcohol or drugs, were associated with lower attitudes and higher career‐related strain among both plateaued and nonplateaued employees. Negative behavioral responses, such as lowering quality or quantity of work, psychological withdrawal, and lateral transfers, were associated with lower attitudes among both groups of employees and lower perceived performance among plateaued employees. Implications for managers and human resource professionals are discussed. 相似文献

The purpose of the present work was to identify general problem solving skills that underlie the production of insight. One
hundred and eighteen participants completed insight problems, analogies, series-completion problems and the Remote Associates
Test. Scores on all measures were related to performance on the insight problems (Pearson r's ranged from .31 to .47, p <
.008). These findings are consistent with the notion that the abilities to apprehend relations and fluency of thought are
involved in insightful problem solving. 相似文献

The number of Non-Profit Organisations (NPOs) has increased in the past years, and they rely on advertising to communicate their causes. Although the effectiveness of NPO advertising has been studied previously, there is still no consensus about which appeal (emotionally positive or negative) increases its effectiveness. On the other hand, the most prevalent research approaches to NPO advertising are traditional research methodologies based on declarative techniques. So, the purpose of this study is to identify which appeal (positive or negative) in NPO advertising is more effective at the three levels of effectiveness (perceptual or communicational effectiveness, psychological or attitudinal effectiveness and behavioural effectiveness), providing a new approach based on the analysis of consumers' unconscious responses to advertising. We conducted an experiment with 113 participants whose neurophysiological responses were evaluated through electroencephalogram (EEG) and eye tracking (ET) while they watched NPO advertisements with a randomly assigned emotional appeal (positive or negative). In addition, a survey revealed behavioural responses. The results showed that considering the psychological or attitudinal effectiveness, positively framed ads are more effective, as there is a positive effect on attitudes towards the ad and a higher positive emotional valence. On the other hand, in perceptual effectiveness, where attention is considered an important variable, the negatively framed ads showed more significant time in the area of interest (AOI) of the image area of the ad, and longer time in the AOI text was observed for positively framed ads. Furthermore, regarding behavioural effectiveness, negatively framed ads seem more effective in eliciting actual donations. The results suggest that a positive appeal is more effective in generating a more positive attitude and a positive emotional valence towards the advertisement, which could benefit the NPO in the long term. But a negative appeal is more effective if the goal is to achieve immediate donations. 相似文献

Surveys of childhood vaccinations are often highly inaccurate, due to parental misreporting. We conducted three experiments to examine the source of the inaccuracies. In Experiment 1, we provided parents with memory aids; these aids did little to improve reporting accuracy. Two further experiments asked whether parents forgot what they knew about their children's vaccinations, or whether they never knew the information. In Experiment 2 we surveyed parents both immediately and ten weeks after their child's medical visit. Accuracy was only slightly better than chance immediately afterwards; ten weeks later performance had not changed significantly. Experiment 3 compared reports in both recall and recognition conditions. Although the recognition condition lowered the response burden on parents it did not produce more accurate reports. We conclude that low levels of accuracy in parental reports on vaccinations appear to reflect poor initial encoding rather than retrieval failure. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

In the current study, we examined associations among early childcare workers’ emotional competence, observed responsiveness, comfort with socioemotional teaching practices, and the quality of their relationships with children in their care. The participants were 100 early childcare workers (72 center-based Early Head Start teachers and 28 family childcare providers). Results showed that caregivers’ emotion regulation ability was positively associated with caregiver–child relational closeness. Understanding and regulation of emotion were both positively associated with childcare workers’ comfort with socioemotional teaching practices. Their observed responsiveness was positively related to relational closeness and negatively related to relational conflict. Findings are consistent with aspects of the prosocial classroom model, which asserts that educators high in emotional and social competence tend to adopt childcare practices that result in supportive relationships with children. Results provide insight into whether childcare workers’ responsiveness to young children and their perceived socioemotional teaching practices provide a pathway between emotional competence and the quality of caregiver–child relationships. 相似文献
