从儿童赌博任务看热执行功能的发展

为考察热执行功能的发展,本研究通过儿童赌博任务检测了60名3～4岁儿童(男女各半)的情感决策。实验结果表明,3岁和4岁儿童在此任务上存在显著的年龄差异,4岁组在各试验组的分数呈上升趋势,他们在试验组2、尤其在试验组4和5中选择有利纸牌的次数显著多于3岁儿童,这反映出情感决策在3～4岁期间发展迅速。此外,儿童在此任务上的成绩存在很多可变性,可能掩盖了性别差异,因而,尽管男孩在最后两个试验组的成绩优于女孩,但性别差异在统计上并不显著。     

Adapted to flee famine: adding an evolutionary perspective on anorexia nervosa

Anorexia nervosa (AN) is commonly attributed to psychological conflicts, attempts to be fashionably slender, neuroendocrine dysfunction, or some combination of these factors. Considerable research reveals these theories to be incomplete. Psychological and societal factors account for the decision to diet but not for the phenomenology of the disorder; theories of biological defects fail to explain neuroendocrine findings that suggest coordinated physiological mechanisms. This article presents evidence that AN's distinctive symptoms of restricting food, denial of starvation, and hyperactivity are likely to be evolved adaptive mechanisms that facilitated ancestral nomadic foragers leaving depleted environments; genetically susceptible individuals who lose too much weight may trigger these archaic adaptations. This hypothesis accounts for the occurrence of AN-like syndromes in both humans and animals and is consistent with changes observed in the physiology, cognitions, and behavior of patients with AN.     

Dissociation of pure korean words and Chinese-derivative words in phonological dysgraphia

Phonological dysgraphia is a writing impairment, characterized by marked disability to spell pronounceable pseudo-words as opposed to relatively mild reduction in ability to spell real words. Within the realm of Korean vocabulary, there are two categories of real words: pure Korean words and Chinese-derivative words. We present a patient with a history of CVA, resulting in phonological dysgraphia and, further, a dissociated performance in the aforementioned two categories of real words. It is suggested that the lexicon for pure Korean words is segregated from that for Chinese-derivative words.

Moral in whose eyes? Cross-cultural differences in moral decision making and behaviour

All people want to feel that they are morally adequate. People tend to evaluate their moral adequacy by judging their behaviour through their own eyes (first-person perspective) or the eyes of others (third-person perspective). People in all cultures use both perspectives, but there may be cultural variations in which perspective takes precedence. By conducting two studies, we explore the way people in face cultures are more likely to secure their moral self-regard through the eyes of others (vs. their own eyes), whereas the opposite is true in case of people from dignity cultures. Study 1 found that people from face culture (Korean participants) cheated to a lesser extent when others were invoked (vs. not invoked), but people from dignity culture (American participants) were not affected by this priming. Study 2 found that moral intentions were more strongly influenced by what participants perceived others to do in moral situations in face (vs. dignity) cultures. In contrast, moral intentions were found to be more strongly influenced by what they believed they should do in moral situations in dignity (vs. face) cultures.     

不同的拼音教学方式对幼儿拼音水平及汉语语音意识发展的影响

本研究用纵向实验的方法考察了分享阅读(故事教学)和传统教学(字母教学)两种拼音教学方式对幼儿园中班儿童的拼音水平和汉语语音意识发展的影响。研究结果表明:(1)相对于无拼音教学组,两种形式的拼音教学均可以显著提高幼儿的字母知识,但分享阅读拼音教学对幼儿字母知识的促进作用更大。(2)分享阅读的拼音教学可以显著提高幼儿的拼读能力,而传统教学对幼儿的拼读能力基本没有促进。(3)分享阅读的拼音教学对幼儿的首音、韵脚和声调意识的发展有显著的促进作用,对幼儿自然发展起来的音节意识的影响很小;传统教学对幼儿的语音意识基本没有促进。     

乙肝治疗路线图与核苷类药物的耐药管理

慢性乙肝治疗的路线图介绍了对核苷类似物耐药的监测时间和处理方法。本文首先介绍了耐药评价的时间点,大多可以采用治疗后12周和24周的评估。如果出现耐药,针对不同情况可以采用换用或者加用没有交叉耐药的不同核苷类似物处理。
