Among these, personal types should be paid more attention to since different personalities mean different learning styles, and different learning styles lead to different levels of proficiency. The present study tries to explore the personal types in terms of extroversion and introversion of the students majoring in physical culture. Based on the investigation in personality types, the implications are discussed and some suggestions are put forward.展开更多

Some strategies to implement the information gap activities are also recommended together with the functions of the instructors via these activities. What information gap activities can teach us in TESOL （teaching English for speakers of other languages） is that information gap activities contribute to setting up a climate of a mutual autonomous learning style both for the learners and the instructors, and these activities activate a diversity in the learning atmosphere.展开更多

At the same time the adaptive value and evolutionary maintenance of different personalities are the subject of debate. Since Pavlov＇s work on dogs, students of comparative cognition have been aware that animals display vast individual differences on cognitive tasks, and that these differences may not be entirely accounted for differences in cognitive abilities. Here, we argue that personality is an important source of variation that may affect cognitive performance and we hypothesise mutual influences between personality and cognition across an individual＇s lifespan. In particular, we suggest that： 1） personality profiles may be markers of different cognitive styles; 2） success or failure in cognitive tasks could affect different personalities differently; 3） ontogenetic changes of personality profiles could be reflected in changes in cognitive performance. The study of such interplay has implications in animal welfare as well as in neuroscience and in translational medicine [Current Zoology 57 （4）： 491-498, 2011].展开更多
