AbstractAn external focus of attention is considered superior to an internal focus for learning and performance. However, findings specific to changing the task difficulty are inconsistent. The present study used a reciprocal aiming task to determine the effects of attentional focus on motor performance using speed-accuracy paradigm. We constrained timing to examine how internal and external focus of attention influenced accuracy when task difficulty changes. The results indicated greater accuracy on the right target and greater consistency on both targets for the external focus condition, regardless of task difficulty. Our results uniquely demonstrated how instruction modified a speed-accuracy task. 相似文献

AbstractChanging automatized movement patterns often leads to initial performance decrements caused by proactive interference. In this study, we scrutinized whether proactive interference could be reduced by inhibiting the to-be-changed movement pattern by means of a physical movement constraint and verbal inhibition instructions, and whether any of the two interventions may be superior. Skilled typists typed short texts as fast and accurately as possible on a regular QWERTZ keyboard. After baseline measures, a new rule prohibiting the use of the left index finger was introduced. Subsequently, participants took part in either a verbal instruction or an additional motor restriction intervention phase. Results revealed that the original rule change was successful in inducing proactive interference in skilled typists. Most importantly, the two interventions similarly reduced proactive interference both immediately following the rule change and after ten practice sessions. We conclude that reducing proactive interference by means of physical motor restrictions and verbal instructions may be equally effective. 相似文献

ABSTRACT Over three studies (i.e., two 2 × 2 experiments and a multi-source field study), we examine the relationship between abusive supervision, leader characteristics, and organizational inclusion on employee outcomes. Drawing on the group value theory of organizational justice and multiple needs theory of organizational justice, we argue that abusive supervision is counterproductive to making employees feel welcome. Specifically, we demonstrate that abusive supervision demoralizes employees’ feelings of organizational inclusion. Additionally, we draw upon research that suggests that the display of hostility inherent in abusive supervision can be perceived differently when it comes from a strategic versus impulsive source. We build upon this reasoning to examine and explain how leader characteristics might alter the effect of abusive supervision on organizational inclusion. More specifically, we suggest that leader political skill (i.e., strategic source) and leader neuroticism (i.e., impulsive source) act as moderators of the relationship between abusive supervision and organizational inclusion. We integrate organizational justice and inclusion theories to demonstrate that abusive supervision can be interpreted as an unwelcoming experience that ultimately has the ability to turn employees into poor organizational citizens (i.e., decrease engagement of OCBs) and future quitters (i.e., increase of turnover intentions). Theoretical and practical implications are discussed. 相似文献

In a series of three experiments, we use children’s noun learning as a probe into their syntactic knowledge as well as their ability to deploy this knowledge, investigating how the predictions children make about upcoming syntactic structure change as their knowledge changes. In the first two experiments, we show that children display a developmental change in their ability to use a noun’s syntactic environment as a cue to its meaning. We argue that this pattern arises from children’s reliance on their knowledge of verbs’ subcategorization frame frequencies to guide parsing, coupled with an inability to revise incremental parsing decisions. We show that this analysis is consistent with the syntactic distributions in child-directed speech. In the third experiment, we show that the change arises from predictions based on verbs’ subcategorization frame frequencies. 相似文献

Recent years have seen a flourishing of Natural Language Processing models that can mimic many aspects of human language fluency. These models harness a simple, decades-old idea: It is possible to learn a lot about word meanings just from exposure to language, because words similar in meaning are used in language in similar ways. The successes of these models raise the intriguing possibility that exposure to word use in language also shapes the word knowledge that children amass during development. However, this possibility is strongly challenged by the fact that models use language input and learning mechanisms that may be unavailable to children. Across three studies, we found that unrealistically complex input and learning mechanisms are unnecessary. Instead, simple regularities of word use in children's language input that they have the capacity to learn can foster knowledge about word meanings. Thus, exposure to language may play a simple but powerful role in children's growing word knowledge. A video abstract of this article can be viewed at https://youtu.be/dT83dmMffnM .
Research Highlights
- Natural Language Processing (NLP) models can learn that words are similar in meaning from higher-order statistical regularities of word use.
- Unlike NLP models, infants and children may primarily learn only simple co-occurrences between words.
- We show that infants' and children's language input is rich in simple co-occurrence that can support learning similarities in meaning between words.
- We find that simple co-occurrences can explain infants' and children's knowledge that words are similar in meaning.
