The role of instruction preference in analogy learning: Brain activity and motor performance

This study examined the role of verbal instruction preference when learning motor skills by analogy. During skill learning, analogies are a useful tool for providing knowledge about how to move. It has been argued that analogy instructions reduce reliance on verbal information processes during motor planning, compared to traditional forms of instruction (i.e., explicit rules about how to move). This may be reflected by reduced verbal activity in the brain, measured by EEG alpha power at the temporal region, as well as reduced verbal-motor cross-communication (EEG T7-Fz coherence) during the preparation phase of a movement. Preference for using verbal or visual instructions is likely to influence the efficacy of analogy instructions. This study investigated whether preference for verbal instructions was related to a) changes in performance and b) changes in verbal-cognitive information processing during performance of an adapted basketball task after instruction by analogy. Basketball novices with a high preference for verbal instructions (n = 15) showed significantly decreased activation of verbal brain regions when they used the analogy (high-alpha power), but their performance remained stable. Novices with a low preference for verbal instructions (n = 13) did not show a significant decrease in activation of verbal regions, and their performance deteriorated significantly after introduction of the analogy instruction. It is likely that both cognitive and performance changes after analogy instruction depend on personal aspects of information processing, such as verbal preference.

生命伦理学的知识场域与现象学问题

生命伦理学还不是一个成熟的学科,研究者还要做许多重要的工作。目前,生命伦理学研究中首要的是对相关知识、基本概念、语词的统一,诸如对生命、医学、疾病、死亡等确立生命伦理语境下的认知,是一项重要的任务。应该挖掘所有人类的理性遗产和文化资源,建立和构建生命伦理学理论框架和体系,从而解决对具体生命伦理问题和现象评价的困难。生命伦理学存在一个多维的知识场域,揭示、解释和勾绘这个场域,对生命伦理学的学科建设具有重要意义。     

The Knowledge Argument and Objectivity

In this paper I argue that Frank Jackson’s Knowledge Argument is better considered not as an argument against physicalism, but as an argument that objective theories must be incomplete. I argue that despite the apparent diversity of responses to the knowledge argument, they all boil down to a response according to which genuine epistemic gains are made when an individual has an experience. I call this the acquaintance response. I then argue that this response violates an intuitive stricture on the objectivity of theories. Therefore, the knowledge argument does show that objective theories cannot provide a complete understanding of the world. The result, however, is that both objective dualism and objective physicalism are refuted by the argument. In the end it is suggested that the notion of “subjective physicalism” is one that should be pursued.

Working memory and vocabulary development in Greek preschool and primary school children

The present research investigated the relative contributions of verbal short-term memory (STM) and working memory (WM) to vocabulary development in the early years among Greek-speaking children. Participants were 5.5-, 7.5-, 8.5- and 9.5-year-old (N = 216) native speakers of Greek, a language differing from English in which most investigations have been conducted. Children were assessed with a receptive vocabulary task, four verbal STM measures (word, digit, and non-word list recall, as well as word list matching), and three verbal WM tasks (listening, counting, and backward digit recall). Results offer support to the view that both STM and WM influence vocabulary development in early stages. Vocabulary was associated with verbal STM at 7.5 and 8.5 years, but only with verbal WM at 5.5 years. Associations declined with age (by 9.5 years), earlier than in English-speaking children. Findings are discussed in relation to Greek language characteristics, demonstrating the importance of cross-cultural investigations.     

Variation in verbal fluency: A latent variable analysis of clustering,switching, and overall performance

Verbal fluency tasks have long been used to assess and estimate group and individual differences in executive functioning in both cognitive and neuropsychological research domains. Despite their ubiquity, however, the specific component processes important for success in these tasks have remained elusive. The current work sought to reveal these various components and their respective roles in determining performance in fluency tasks using latent variable analysis. Two types of verbal fluency (semantic and letter) were compared along with several cognitive constructs of interest (working memory capacity, inhibition, vocabulary size, and processing speed) in order to determine which constructs are necessary for performance in these tasks. The results are discussed within the context of a two-stage cyclical search process in which participants first search for higher order categories and then search for specific items within these categories.
