The bimanual coupling literature supposes an inherent drive for synchrony between the upper limbs when making discrete bimanual movements. The level of synchrony is argued to be task dependent, reliant on the visual demands of the two targets, and the result of a complex pattern of hand and eye movements (Bingham, Hughes, & Mon-Williams, 2008 ; Riek, Tresilian, Mon-Williams, Coppard, & Carson, 2003 ). However, recent work by Bruyn and Mason ( 2009 ) suggests that temporal coordination is not solely influenced by visual saccades. In this experimental series, a total of 8 participants performed congruent movements to targets either near or far from the midline. Targets far from the midline, requiring a visual saccade, resulted in greater terminal asynchrony. Initial and terminal asynchrony were not consistent, but linked to the task demands at that stage of the movement. If the asynchrony evident at the end of a bimanual movement is due to a complex pattern of hand and eye movements then the removal of visual feedback should result in an increase in synchrony. Sixteen participants then completed congruent and incongruent bimanual aiming movements to near and/or far targets. Movements were made with or without visual feedback of hands and targets. Analyses revealed that movements made without visual feedback showed increased synchrony between the limbs, yet movements to incongruent targets still showed greater asynchrony. We suggest that visual constraints are not the sole cause of asynchrony in discrete bimanual movements. 相似文献

Face and symmetry processing have common characteristics, and several lines of evidence suggest they interact. To characterize their relationship and possible interactions, in the present study we created a novel library of images in which symmetry and face-likeness were manipulated independently. Participants identified the target that was most symmetric among distractors of equal face-likeness (Experiment 1) and identified the target that was most face-like among distractors of equal symmetry (Experiment 2). In Experiment 1, we found that symmetry judgments improved when the stimuli were more face-like. In Experiment 2, we found a more complex interaction: Image symmetry had no effect on detecting frontally viewed faces, but worsened performance for nonfrontally viewed faces. There was no difference in performance for upright versus inverted images, suggesting that these interactions occurred on the parts-based level. In sum, when symmetry and face-likeness are independently manipulated, we find that each influences the perception of the other, but the nature of the interactions differs. 相似文献

The attentional blink (AB) is a transient attention cost that is shown when report accuracy for a second target (T2) is reduced when T2 is presented within approximately 500?ms of a first target (T1). Thus, by definition an AB is only observed when T2 accuracy is reduced at short relative to long T1?CT2 separations, and the magnitude of the AB is reflected in the change in T2 performance across target separations. However, the designs, analyses, and interpretations of several studies of the AB have suggested a lack of clear definitions about what constitutes a demonstration of the AB, what constitutes a modulation of the AB across participant groups or manipulations, and how AB magnitude might best be represented accurately as a single value for a given individual. In this article, we discuss the important conceptual and methodological issues that should be considered when obtaining, analyzing, and interpreting AB data, and we discuss the pros and cons of various approaches while providing suggestions as to how best to validly represent the AB and its modulations. 相似文献

Response to DiNunno's “Long-Term Group Psychotherapy for Women Who Are Survivors of Childhood Abuse”

Trauma impels people both to withdraw from close relationships and to seek them desperately. The profound disruption in basic trust, the common feelings of shame, guilt, and inferiority, and the need to avoid reminders of the trauma that might be found in social life, all foster withdrawal from close relationships. But the terror of the traumatic event intensifies the need for protective attachments. The traumatized person therefore frequently alternates between isolation and anxious clinging to others [Herman, 1992, p. 56]. 相似文献

This study reports findings from comparative samples of sixth-grade Chinese and U.S. students' interpretations of the equal sign. Ninety-eight percent of the Chinese sample correctly answered 4 items indicating conceptions of equality and provided conceptually accurate explanations. In contrast, only 28% of the U.S. sample performed at this level. We examine how teacher preparation materials, students' textbooks and teachers' guidebooks treat equality in each country. U.S. teacher preparation textbooks rarely interpreted the equal sign as equivalence. On the contrary, Chinese textbooks typically introduced the equal sign in a context of relationships and interpreted the sign as “balance,” “sameness,” or “equivalence” and only then embedded the sign with operations on numbers. 相似文献

For inexperienced sales representatives, success provides an important learning opportunity from which to build confidence and hone strategies. Such learning is derived from the attributions one makes for success and how those attributions shape future behavior. This research investigates the interpretation and behavioral intentions of inexperienced sales representatives following a successful sales call using a sample of financial services representatives. Surprisingly, we found that achieving success did not assure the adoption or future use of the strategy that garnered that success. These results suggest that inexperienced sales representatives may require managerial attention to fully understand and appropriately assimilate their sales successes. Implications for managers and future research are discussed. 相似文献

Some studies suggest that religiosity may be related to health outcomes. The current investigation, involving 92,395 Women's Health Initiative Observational Study participants, examined the prospective association of religious affiliation, religious service attendance, and strength and comfort from religion with subsequent cardiovascular outcomes and death. Baseline characteristics and responses to religiosity questions were collected at enrollment. Women were followed for an average of 7.7 years and outcomes were judged by physician adjudicators. Cox proportional regression models were run to obtain hazard ratios (HR) of religiosity variables and coronary heart disease (CHD) and death. After controlling for demographic, socioeconomic, and prior health variables, self-report of religious affiliation, frequent religious service attendance, and religious strength and comfort were associated with reduced risk of all-cause mortality [HR for religious affiliation = 0.84; 95% confidence interval (CI): 0.75–0.93] [HR for service attendance = 0.80; CI: 0.73–0.87] [HR for strength and comfort = 0.89; CI: 0.82–0.98]. However, these religion-related variables were not associated with reduced risk of CHD morbidity and mortality. In fact, self-report of religiosity was associated with increased risk of this outcome in some models. In conclusion, although self-report measures of religiosity were not associated with reduced risk of CHD morbidity and mortality, these measures were associated with reduced risk of all-cause mortality. 相似文献

The influence of repression on peripheral blood lymphocyte surface markers and diurnal decline in salivary cortisol following multiple disasters was examined. Participants were sampled at 2 to 8 weeks after a severe fire and flood, and again 1 year later. High distress, low distress, and repression groups were formed utilizing self-reported distress and systolic blood pressure during a disaster recall interview. A main effect for group was identified for CD56+ cells (NK cells), with repressors and high distress participants demonstrating lower percentage of NK cells than low distress participants. At Time 1 repressors demonstrated significantly higher percentage of CD56+CD69+ cells (activated NK cells) than high and low distress participants. From Time 1 to Time 2, repressor participants showed a significant decline in the percentage of activated NK cells. Repressors demonstrated attenuated decline in salivary cortisol compared to low distress participants. Health implications for disaster recovery are discussed. 相似文献
