Preserved re-experience of discrete emotions: Amnesia and executive function

Amnesic patients can re-experience emotions elicited by forgotten events, suggesting that brain systems for episodic and emotional memory are independent. However, the range of such emotional memories remains under-investigated (most studies employing just positive–negative emotion dyads), and executive function may also play a role in the re-experience of emotions. This is the first investigation of the intensity of the emotional re-experience of a range of discrete emotions (anger, fear, sadness, and happiness) for a group of amnesic patients. Twenty Korsakoff syndrome (KS) patients and 20 neurologically normal controls listened to four novel emotional vignettes selectively eliciting the four basic emotions. Emotional experience was measured using pen-and-paper Visual Analogue Mood Scales and episodic memory using verbal recollections. After 30 min, the recollection of stories was severely impaired for the patient group, but the emotional re-experience was no different from that of controls. Notably, there was no relationship between episodic recall and the intensity of the four emotions, such that even profoundly amnesic patients reported moderate levels of the target emotion. Exploratory analyses revealed negative correlations between the intensity of basic emotions and executive functions (e.g., cognitive flexibility and response inhibition) for controls but not patients. The results suggest that discrete emotions can be re-experienced independently of episodic memory, and that the re-experience of certain discrete emotions appears to be dampened by executive control. KS patients with absent or mild cognitive symptoms should benefit from emotion-regulation interventions aimed at reducing the recognized affective burden associated with their episodic memory deficit.     

Relationship between poverty and health among adolescents

Although the effect of low socioeconomic status on the health of adolescents has been documented, the mechanism by which this occurs is not well understood. Furthermore, improving adolescent health through public health policy typically requires the presence of one or more modifiable risk factors which can be targeted for intervention. In spite of the well-documented negative associations between poverty and health, few modifiable risk factors have been identified. This study used the Evans-Stoddart Model of Health and Well-Being as a framework to examine data on 1,759 adolescents, aged 12 to 19, collected as part of the 1994 National Population Health Survey. Results not only confirm the relationship between income and health, but suggest how the pathway operates through the social environment, lifestyle differences, access to health care, and a reduced sense of self-esteem and self-mastery. Bivariate and multivariate analyses found positive associations between physical activity levels and self-esteem and mastery. We interpret these findings as preliminary evidence that it might be possible to buffer the impact of poverty on health through policies which increase physical activity levels among those living in poverty. Such policies could also include a secondary goal of increasing the activity levels among inactive adolescents who are not living in poverty, as they will derive benefits from this increase, both psychologically and physiologically.     

Language-dependent recall of autobiographical memories

Two studies of autobiographical memory explored the hypothesis that memories become more accessible when the linguistic environment at retrieval matches the linguistic environment at encoding. In Experiment 1, Russian-English bilinguals were asked to recall specific life experiences in response to word prompts. The results supported the hypothesis of language-dependent recall: Participants retrieved more experiences from the Russian-speaking period of their lives when interviewed in Russian and more experiences from the English-speaking period of their lives when interviewed in English. In Experiment 2, the language of the interview was varied independently from the language of the word prompts. Both variables were found to influence autobiographical recall. These findings show that language at the time of retrieval, like other forms of context, plays a significant role in determining what will be remembered.

近五十年来台湾地区士林哲学之研究与前瞻

根据祁尔松（Etienne Gilson）的说法,中世纪哲学,尤其是十三世纪的思想,是基督宗教哲学。本文按其在台湾发展时所袭用的名词,称之为士林哲学。士林哲学之传入中国,虽然早在利玛窦时期（1550—1610）已经开始,但真正成为学术思想之主流之一,是最近五十年来在台湾地区的发展。20世纪初士林哲学初传入台湾时,当时的思想环境,对基督宗教哲学并不十分友善,这种种情况,与中世纪的思想家,面对信仰与神学之挑战相似。当时的思想家,融合各种不同的思想派系,对柏拉图与亚理斯多德的观念,重新诠释与批判,批判与诠释是创新的基础。所以,中世纪可说是哲学的第二春,而中世纪哲学之精华,即全盛期的士林哲学。十四世纪唯名论之后,士林哲学逐步式微,于十九世纪末再兴。本文认为,士林哲学在台湾发展之过程,与其在中世纪之盛行,及十九世纪末之再兴,背景虽异但有不少相似之处,而这些相似之处,正是士林哲学之基本思想与立场。本文对台湾士林哲学之发展,从四方面探讨：（1）回到形上学之根以面对新的挑战;（2）形上学基本立场与概念之说明;（3）反思与批判;（4）未来发展之方向。本文所参考之资料,一是已发表之学术文献;其二是与学者们之正式交谈——如学术演讲、座谈会等,及非正式之谈话、访问等。     

Shared and separate systems in bilingual language processing: converging evidence from eyetracking and brain imaging

The neurological and cognitive aspects of bilingual language processing were examined in late Russian-English bilinguals using headband-mounted eyetracking and functional neuroimaging. A series of three eyetracking studies suggested that, at early stages of word recognition, bilinguals can activate both languages in parallel, even when direct linguistic input is in one language only. A functional neuroimaging study suggested that, although the same general structures are active for both languages, differences within these general structures are present across languages and across levels of processing. For example, different centers of activation were associated with first versus second language processing within the left Inferior Frontal Gyrus, but not within the Superior Temporal Gyrus. We suggest that parallel activation (as found with eyetracking) and shared cortical structures (as found with fMRI) may be characteristic of early stages of language processing (such as phonetic processing), but the two languages may be using separate structures at later stages of processing (such as lexical processing).     

Dyslexia and handedness: developmental phonological and surface dyslexias are associated with different biases for handedness

Developmental disorders of reading and spelling have long been associated with increased left- and mixed-handedness but the evidence has been controversial. The right shift (RS) theory of handedness and cerebral dominance, developed by Annett from 1972 onward, offers resolutions to several puzzles about laterality in the so-called dyslexias. This review of findings in the light of the theory shows that "phonological" dyslexics are less likely to be right-handed, while "surface" or "dyseidetic" dyslexics are more likely to be right-handed than the general population.     

The empathetic mind: the essence of human spirituality

The discovery of mirror neurons has led to some exciting research into the role of the brain and human empathy. Empathy is a significant element in human relationality and, therefore, human spirituality. This article will focus on the links between mirror neurons and human empathy and education. It will then examine how technology may be a factor in causing the erosion of empathy in today’s world, leading to school violence and bullying. It will conclude by offering some guidelines for educational programmes which may lead to the nurturing of children’s empathy.     

The many faces of the Still-Face Paradigm: A review and meta-analysis

The Still-Face Paradigm (SFP) designed by Tronick, Als, Adamson, Wise, and Brazelton (Tronick, E., Als, H., Adamson, L., Wise, S., & Brazelton, T. B. (1978). Infants response to entrapment between contradictory messages in face-to-face interaction. Journal of the American Academy of Child and Adolescent Psychiatry, 17, 1–13) has been used for many different purposes in over 80 empirical studies. In the current paper, the nature and correlates of infant behavior in the SFP were examined in a systematic narrative review and a series of meta-analyses. The results of the meta-analyses confirmed the classic still-face effect of reduced positive affect and gaze, and increased negative affect, as well as a partial carry-over effect into the reunion episode consisting of lower positive and higher negative affect compared to baseline. The still-face effect is very robust as it was found regardless of most sample variations such as infant gender and risk status, and regardless of most procedural variations, such as the length of the SFP episodes and the use of intervals between episodes. The few moderator effects that were found in the meta-analyses tended to put findings from the narrative review in a new perspective. Additional meta-analyses confirmed the narrative review in finding that higher maternal sensitivity predicted more infant positive affect during the still-face. Infants’ higher positive affect and lower negative affect during the still-face were predictive of secure attachment at age 1 year. The meta-analytic results for maternal depression were equivocal. Implications for future research include a need for studies testing the role of the adults’ identity (parent versus stranger, mother versus father) to elucidate the relationship-specificity of the still-face effect. Also, the role of maternal sensitivity and temperament as potential moderators of the still-face effect need to be examined further. On a procedural level, the effects of the timing of the still-face and of the duration of the reunion on infant responses deserve future research attention.
