理性看待微创外科

所谓“微创”,乃是传统外科发展的伸延和提升。微创不等于无创,微创需要科学的决策,同时微创要运用循证医学。微创具有广阔的前景,但它的治疗之路依然很长。它需要进一步的完善。目前,还不是丰收的季节。

A common representational system governed by Weber's law: nonverbal numerical similarity judgments in 6-year-olds and rhesus macaques

This study compared nonverbal numerical processing in 6-year-olds with that in nonhuman animals using a numerical bisection task. In the study, 16 children were trained on a delayed match-to-sample paradigm to match exemplars of two anchor numerosities. Children were then required to indicate whether a sample intermediate to the anchor values was closer to the small anchor value or the large anchor value. For two sets of anchor values with the same ratio, the probability of choosing the larger anchor value increased systematically with sample number, and the psychometric functions superimposed when plotted on a logarithmic scale. The psychometric functions produced by the children also superimposed with the psychometric functions produced by rhesus monkeys in an analogous previous experiment. These examples of superimposition demonstrate that nonverbal number representations, even in children who have acquired the verbal counting system, are modulated by Weber's law.     

Specific phonological impairments in dyslexia revealed by eyetracking

Phonological deficits in dyslexia are typically assessed using metalinguistic tasks vulnerable to extraneous factors such as attention and memory. The present work takes the novel approach of measuring phonology using eyetracking. Eye movements of dyslexic children were monitored during an auditory word recognition task in which target items in a display (e.g., candle) were accompanied by distractors sharing a cohort (candy) or rhyme (sandal). Like controls, dyslexics showed slower recognition times when a cohort distractor was present than in a baseline condition with only phonologically unrelated distractors. However, unlike controls, dyslexic children did not show slowed recognition of targets with a rhyme distractor, suggesting they had not encoded rhyme relationships. This was further explored in an overt phonological awareness test of cohort and rhyme. Surprisingly, dyslexics showed normal rhyme performance but poorer judgment of initial sounds on these overt tests. The results implicate impaired knowledge of rhyme information in dyslexia; however they also indicate that testing methodology plays a critical role in how such problems are identified.

维果茨基心理学理论述评

维果茨基是苏联早期一位才华横溢的杰出心理学家,社会文化历史学派的创始人。近年来国际上出现的维果茨基研究热,充分显示了维果茨基心理学思想对现代心理科学的重要的现实意义。维果茨基的心理学理论异常丰富,主要包括活动理论、工具理论、思维和言语理论、教学和发展理论、心理学方法论等。维果茨基心理学理论是对意识的文化历史决定的研究的重要贡献,其理论不足之处主要带有抽象社会观点的色彩等。

Middle Aging in Women: Patterns of Personality Change from the 30s to the 50s

This three-sample study focused on changes in four key features of women's personalities (identity, generativity, confident power, and concern about aging) over the course of middle age. Based on women's retrospective and concurrent feelings about their lives in their 30s, 40s, and 50s, scales were developed and validated for the four themes. We found that identity certainty, generativity, confident power, and concern about aging all were experienced as more prominent in middle age (the 40s) than in early adulthood (the 30s). We also found that these elements of personality were rated even higher in the 50s than the 40s. Scores seemed to be a function of age more than historical period or particular experiences in social roles. Scores on identity certainty, generativity, and confident power were positively related to well-being, while concern about aging was negatively related to well-being.
