During reading, some information about the word to the right of fixation in the parafovea is typically acquired prior to that word being fixated. Although some degree parafoveal processing is uncontroversial, its precise nature and extent are unclear. For example, can it advance up to the level of semantic processing? Additionally, can it extend across more than two spatially adjacent words? Affirmative answers to either of these questions would seemingly be problematic for serial-attention models of eye-movement control in reading, which maintain that attention is allocated to only one word at a time (see Reichle, 2011). However, in this paper we report simulation results using one such model, E-Z Reader (Reichle, Pollatsek, Fisher, & Rayner, 1998), to examine the two preceding questions. These results suggest the existence of both semantic preview and N+2 preview effects, indicating that they are not incompatible with serial-attention models. We discuss the implications of these findings for models of eye-movement control in reading and provide a new theoretical framework for conceptualizing parafoveal processing during reading and its influence on eye movement behaviour. 相似文献

ObjectivesThis systematic review provides an overview of research elucidating the relationship between fundamental movement skills (FMS) and physical activity (PA) in children and adolescents.DesignSystematic review.MethodProspective studies were identified from searches in Cochrane Library, BioMed Central, Education Resources Information Center (ERIC), PubMed, Scirus and SciVerse Science Direct from 2000 through 2013. We screened the titles and abstracts for eligibility, rated the methodological quality of the studies, and extracted data.ResultsWe identified 23 studies meeting our relevancy criteria. The quality score of the studies ranged from 44% to 89%. Overall relationships between FMS and PA or relationships specific for gender and skill were identified in several studies. The variety of methods for assessing PA and FMS make the comparison of study results difficult. We found strong evidence from cross-sectional studies for a positive relationship between FMS and organized physical activities. Motor skill competency was only of low predictive value for the physical activity level in adults.ConclusionsThe results of this review suggest that a cause–effect relationship between FMS and PA is suspected but has not been demonstrated yet. The identification of a causal relationship appears very important to ensure feasibility of practical implementation. This could provide aids for decision making for teachers and coaches, but also for therapists' decision guidance to create training, lessons and therapy adequate to the target group. 相似文献

相对于其它评价中心技术而言,在无领导小组讨论中考官因素对评分结果的影响尤为重要.本研究主要探讨无领导小组讨论中新手考官的工作记忆与人格对其评分有效性的影响.结果发现,首先,新手考官的评分者一致性较低,评分准确度较差.其次,工作记忆和人格的部分因素分别从不同方面影响新手考官的评分有效性,具体表现在:(1)利他性越强,新手考官评分总均值的准确性越高,且评分结果越宽松;(2)新手考官的决断性越强,对所有应聘者做出有效区分的准确性越高;(3)新手考官的沉稳性越高,对各维度的区分越有效;(4)注意转换和抑制能力对新手考官的晕轮效应及其在各个维度上进行区分的准确度有抑制作用. 相似文献

The Motivating Role of Perceived Right Violation and Efficacy Beliefs in Identification with the Italian Water Movement 下载免费PDF全文
Because individuals' fundamental right to water is often taken for granted, little is known about why individuals participate in water activism. We examine how individuals identify with and intend to participate in the Italian Water Movement to defend the “public management” of water supply. Building on the collective‐action literature, we test an explanatory model in which the perceived violation of the right to water and group and participative‐efficacy beliefs increase movement identification, which predicts subsequent activism. Study 1 (N = 153 activists) largely confirmed our hypotheses: right violation and participative efficacy uniquely influenced movement identification, which in turn predicted activism. Study 2 corroborated these findings by employing a broader sample of 132 Italian citizens, with right violation, participative and group‐efficacy beliefs predicting movement identification, which in turn predicted activism. We discuss the theoretical and practical implications of these findings. 相似文献

The aim of this study was to investigate the patterns of contralateral motor overflow (i.e. mirror movement) between the homologous body parts on the right and left side, in stroke patients during single-finger and multi-finger maximum force production tasks. Forty subjects, including stroke (n = 20) and normal subjects (n = 20), participated in this study. The stroke subjects maximally pressed force sensors with their fingers in a flexed position using a single (index, middle, ring, or little) or all fingers (all 4 fingers) using the impaired (IH) or unimpaired (UIH) hand, while the non-patient subjects used their right hands for the same tasks. The maximal voluntary forces in the ipsilateral and unintended pressing forces of each contralateral finger were recorded during the tasks. The magnitude of motor overflow to the contralateral side was calculated using the index of contralateral independence (CI). During the single finger tasks, the finger CI was significantly decreased in the UIH (91%) compared with that in the IH (99%) or normal hands (99%). Likewise, the multiple finger tasks showed that the CI was significantly lower in the UIH (84%) compared with that in the IH (96%) or normal hands (99%). However, the maximal forces were significantly lower in the IH relative to those in the UIH and normal hands. These data demonstrate that stroke patients have greater motor overflow from the UIH to the IH. 相似文献

本研究采用眼动追踪技术,通过对预期性和词频、预期性和笔画数在词汇识别过程中是否存在交互作用进行考察,以探讨预期性效应对词汇识别产生影响的加工阶段。结果显示,预期性和词频、预期性和笔画数之间均不存在交互作用。由此表明,预期性、词频和笔画数均独立地对中文文本阅读中的词汇识别产生显著的影响,该结果符合E-Z读者模型的研究假设。 相似文献

Sense of agency refers to the experience that one’s self-generated action causes an event in the external environment. Here, we review the behavioural and brain evidence of aberrant experiences of agency in movement disorders, clinical conditions characterized by either a paucity or an excess of movements unrelated to the patient’s intention. We show that specific abnormal agency experiences characterize several movement disorders. Those manifestations are typically associated with structural and functional brain abnormalities. However, the evidence is sometimes conflicting, especially when considering results obtained through different agency measures. The present review aims to create order in the existing literature on sense of agency investigations in movement disorders and to provide a coherent overview framed within current neurocognitive models of motor awareness. 相似文献

In two experiments, subjects trained in data entry, typing one 4-digit number at a time. At training, subjects either typed the numbers immediately after they appeared (immediate) or typed the previous number from memory while viewing the next number (delayed). In Experiment 2 stimulus presentation time was limited and either nothing or a space (gap) was inserted between the second and third digits. In both experiments after training, all subjects completed a test with no gap and typed numbers immediately. Training with a memory load improved speed across training blocks (Experiment 1) and eliminated the decline in accuracy across training blocks (Experiment 2), thus serving as a cognitive antidote to performance decrements. An analysis of each keystroke revealed different underlying processes and strategies for the two training conditions, including when encoding took place. Chunking (in which the first and last two digits are treated separately) was more evident in the immediate than in the delayed condition and was exaggerated with a gap, even at test when there was no gap. These results suggest that such two-digit chunking is due to stimulus encoding and motor planning processes as well as memory, and those processes transferred from training to testing. 相似文献
