小学六年级学生写作构思策略培养的实验研究

本研究运用心理模拟法创立了写作构思活动模式,并根据心智技能按阶段形成的理论对构思策略进行了分阶段培养。结果表明:①写作构思活动的实践模式可以有效地提高学生的写作构思策略水平,并进而促进其写作技能整体水平的提高;②小学六年级学生在写作技能上不存在明显的性别差异,智力水平对写作技能也没有明显影响;③学生原有的写作技能水平对于当前的写作活动有显著影响,教师在教学前应设法了解学生的写作水平。     

Visual spatial skill: a consequence of learning to read?

Does learning to read influence one’s visual skill? In Study 1, kindergartners from Hong Kong, Korea, Israel, and Spain were tested on word reading and a task of visual spatial skill. Chinese and Korean kindergartners significantly outperformed Israeli and Spanish readers on the visual task. Moreover, in all cultures except Korea, good readers scored significantly higher on the visual task than did less good readers. In Study 2, we followed 215 Hong Kong Chinese kindergartners across 1 year, with word reading and visual skills tested twice. In this study, word reading at Time 1 by itself predicted 13% of unique variance in visual skill at Time 2. Together, these results underscore the potential importance of the process of learning to read for shaping one’s visual spatial skill development.

Athletics and executive functioning: How athletic participation and sport type correlate with cognitive performance

ObjectivesThis study aims to further the knowledge regarding the documented link between physical exercise and cognitive function. Specifically, we examined the relationship between the type and level of sports in which college students participate and their executive functioning (EF).DesignWe utilized a 3-way quasi-experimental design, and grouped participants by athletic status (athlete or non-athlete), sport type (self-paced, externally paced, or non-athlete; see Singer, 2000), and level (high-skilled or recreational).MethodsWe evaluated EF by administering a battery of validated tests of decision making, problem solving, and inhibition.ResultsWe found that athletes scored higher on some of the EF measures than non-athletes. Furthermore, we observed that scores varied by sport type according to which subset of EF each test measured. Self-paced athletes scored highest on an inhibition task, and externally paced athletes scored highest on a problem-solving task.ConclusionsOur results suggest that athletes outperform non-athletes on tests of such EF domains as inhibition and problem solving, and that different types of athletic experience may correlate with higher levels of particular EF domains.     

Kinds of chance in games and sports

While talking about sports (and games) we use such expressions as ‘random victory’, ‘winning by accident’, ‘skill against luck’, ‘chance (fortune) favours the better player’, etc. Unfortunately, chance-related notions that occur in these expressions are not well defined—their meaning is vague and it is not clear whether they refer to one or many different phenomena. Because such phenomena play an important role in sport, from the viewpoint of the philosophy of sport it is necessary to give a systematic account of this topic. Although the works of De Wachter, Simon, Dixon, Breivik and Loland contain many important insights, there is still a room for further research in this field. The author tries to establish a typology of phenomena that could generally be called ‘chance-phenomena’, which however, should be precisely distinguished. As such the primary task is to present an analysis of several different kinds of chance in sports. In constructing this typology the author uses both the distinction between different kinds of games (performative vs. kinetic) as well as analysis of structure of a game (four constitutive elements: players, constitutive rules, material substrate of the game and the world of the game). The most important method used is phenomenological analysis, especially Ingarden-style analysis. These kinds of ‘chance-phenomena’ are: aleatoriness, chaos, irregularity, imprecision and arbitrariness. The paradigm cases of each kind of chance are discussed. The genesis and functions of the respective phenomena in sports and games are also shown, as well as their position in the structure of the game. Such analytic work should precede any solutions of the chance vs. skill problem, or other problems concerning chance in sport. As a test of usefulness of the provided distinctions, the author considers the veracity of the judgements expressed in such sentences as ‘Fortune favours the better player’.     

Focus of attention and automaticity in handwriting

This study investigated the nature of automaticity in everyday tasks by testing handwriting performance under single and dual-task conditions. Item familiarity and hand dominance were also manipulated to understand both cognitive and motor components of the task. In line with previous literature, performance was superior in an extraneous focus of attention condition compared to two different skill focus conditions. This effect was found only when writing with the dominant hand. In addition, performance was superior for high familiarity compared to low familiarity items. These findings indicate that motor and cognitive familiarity are related to the degree of automaticity of motor skills and can be manipulated to produce different performance outcomes. The findings also imply that the progression of skill acquisition from novel to novice to expert levels can be traced using different dual-task conditions. The separation of motor and cognitive familiarity is a new approach in the handwriting domain, and provides insight into the nature of attentional demands during performance.     

An assessment of needed sales management skills

The skills required of sales managers are vitally important to the success of the firm's selling effort; however, there has not been a recent review that identifies these needed skills. Based on a survey of sales executives from 145 companies, this research develops a taxonomy of key sales management skills. The perceived importance of these skills is reported based on the level of management, gender and the performance level of the firm. In addition to identifying the relative importance of the various sales management skills, they were found to group into three conceptual dimensions relating to interpersonal, technical and strategic skills. The results also indicate that significant differences in the perceived level of skill importance exist based on level of management, years managing salespeople, gender and on three dimensions of the respondent's firm performance.     

Speech Motor Skill and Stuttering

The authors review converging lines of evidence from behavioral, kinematic, and neuroimaging data that point to limitations in speech motor skills in people who stutter (PWS). From their review, they conclude that PWS differ from those who do not in terms of their ability to improve with practice and retain practiced changes in the long term, and that they are less efficient and less flexible in their adaptation to lower (motor) and higher (cognitive–linguistic) order requirements that impact on speech motor functions. These findings in general provide empirical support for the position that PWS may occupy the low end of the speech motor skill continuum as argued in the Speech Motor Skills approach (Van Lieshout, Hulstijn, & Peters, 2004).
