汉语元音对声调感知边界的影响

本项研究基于现代汉语普通话声调感知具有范畴性这一结论(Wang, 1976), 以普通话中6个单元音(/a//?//F//i//u//y/, 即拼音a、o、e、i、u、ü)阴平(T1)到阳平(T2)调的连续统(continuum)为实验语料, 用专业语音学软件Praat合成连续统语音样本, 对20名平均年龄为22.90岁的普通话母语者进行声调感知实验, 即让被试对所听刺激进行T1或T2的二选一鉴别测试(identification test), 从而探究单元音的内在音高(intrinsic pitch)与声调感知边界(boundary)的关系。本文借鉴Wang (1976)和Peng等(2010)对元音/i/声调连续统的合成方法, 使声调感知研究拓展到普通话中除/i/之外的其他5个单元音, 对以上两项研究起到一定的对照作用。研究发现, 元音会对T1到T2的声调范畴感知边界位置产生影响, 低元音/a/的内在音高较低, 其边界位置亦始终低于其他元音, 且具有显著性差异, 实验结果证明, 内在音高会对感知边界产生影响, 从而支持了Ohala和Eukel (1976)的“舌位拉伸”假说。     

关于普通话声调知觉中心的初步研究

通常将普通话单音节的声调F0曲线划分成“弯头段”、“调型段”和“降尾段”。考察“调型段”的具体位置和相对长度,对普通话语音教学,对开发语音识别和语音合成系统,都是很有意义的。本文使用两大类合成刺激连续体,通过辨认试验,初步确定了“调型段”在音节F0曲线上的位置,即一个单音节,不论是清声母音节,还是浊声母音节,也不论是何种声调和调域,其声调知觉中心(P-CT)的位置位于韵母段中部,而且,只要“调型段”的长度为浊音段的一半左右,就可能被感知成相应的调类。     

Jungian approach to human aggression with special emphasis on war

Cross-cultural and interdisciplinary agreement as to the universality of aggressive behavior and warfare is compatible with Jung's [(1959): “The Archetypes and the Collective Unconscious. The Collected Works of C. G. Jung, Vol 9, Part I, Para 3.” London: Routledge] theory of archetypes functioning as components of the human collective unconscious. Jungian formulations involve a phylogenetic view of psychic phenomena since archetypes are conceived as neuropsychic entities which evolved through natural selection. It is argued that the banding together of young males for the purpose of aggressive pursuits such as hunting, intergroup conflict, and warfare is a biologically transmitted propensity mediated by archetypal structures in the human brain-psyche. Universally apparent patterns of affiliative and hostile behaviors are linked to Chance's [(1988): “Social Fabrics of the Mind.” London: Lawrence Erlbaum Associates] hedonic and agonic modes and seen as later ontological expressions of archetypal structures responsible in childhood for formation of bonds of attachment to familiars and avoidance and wariness of strangers. Erikson's [(1984): Yale Review 73(4): 481–486] concept of pseudospeciation is associated with Jung's concept of shadow projection to elucidate the phenomena of patriotism, xenophobia, national paranoia, Lorenz's [(1966): “On Aggression.” London: Methuen & Co.] “militant enthusiasm,” propaganda, and mobilization for war. Finally, it is argued that peace between nations can be promoted through conscious awareness of archetypally determined patterns of intergroup conflict and a collective resolve not to pseudospeciate our neighbors. © 1995 Wiley-Liss, Inc.     

Comorbid depression and heart rate variability as predictors of aggressive and hyperactive symptom responsiveness during inpatient treatment of conduct‐disordered,ADHD boys

The primary objective of the present study was to assess the utility of (1) comorbid depression and (2) parasympathetic influence on cardiac function as markers for treatment response among aggressive preadolescent males. Inpatient records of 53 patients with conduct disorder and attention deficit hyperactivity disorder (17 with a comorbid depressive disorder) were examined, including an intake electrocardiogram and daily tallies of several indices of aggressive behavior across 3 weeks of stay. The relations of comorbid depression, heart rate variability, and residualized heart rate (primarily of sympathetic origin) to treatment response were assessed through analyses of linear growth functions. Significant vagal tone by diagnostic status interactions were obtained for both frequency and duration indices of aggression, whereby nondepressed patients with high vagal tone deteriorated and depressed patients with high vagal tone improved during hospitalization. No such relation was found for attention deficit hyperactivity disorder symptoms. Patients in the comorbid group also exhibited greater heart rate variability than their nondepressed counterparts. Furthermore, residualized heart rate was predictive of maternal substance use and paternal incarcerations. These findings suggest complex relations among treatment response, comorbid depression, and emotion regulation in male preadolescents with severe behavior disorders. Additionally, the differential prediction afforded by vagal tone and residualized heart rate underscores the importance of assessing both parasympathetic and sympathetic indices of cardiac function as distinct physiological markers.

Hedonic Evaluation over Short and Long Retention Intervals: The Mechanism of the Peak–End Rule

The peak–end rule is used to explain how people make retrospective hedonic evaluations. This study advances our understanding of its mechanism by identifying the different effects of the rule on such evaluations over short and long retention intervals. The results of two experiments show that (i) respondents constructed their retrospective hedonic evaluations on the basis of the peak and end affects only over a short retention interval, not over a long one; and (ii) respondents relied on episodic information to construct their evaluations over a short retention interval, whereas they relied on both semantic and episodic information to construct their evaluations over a long retention interval. Our study also suggests that the “watershed” between short and long retention intervals is likely to lie between 3 and 7 weeks. Copyright © 2012 John Wiley & Sons, Ltd.     

Life satisfaction goes with pleasure and personal growth goes with interest: Further arguments for separating hedonic and eudaimonic well-being

Some theories suggest that pleasure and interest are separable emotions, with distinct functions and phenomenology. This study proposes a functional model of well-being that draws on these insights. It argues that both pleasure and satisfaction are elements of hedonic well-being and that their main function is to reward goal achievement and to mentally signalize that the body is in homeostatic stability. In contrast, the main function of interest is to promote mental and physical growth, and to suppress hedonic tendencies of premature returns to a homeostatic balance during difficult strivings. The feeling of interest facilitates personal growth, and is thus an indicator of eudaimonic well-being. A follow-up study (N?=?145 Norwegian students) gave empirical support to these assumptions. Life satisfaction predicted feelings of pleasantness while personal growth predicted feelings of interest. With a projective technique, it was further demonstrated that satisfaction produces pleasant stories, but not interesting stories.

Neural control of fundamental frequency rise and fall in Mandarin tones

The neural mechanisms used in tone rises and falls in Mandarin were investigated. Nine participants were scanned while they named one-character pictures that required rising or falling tone responses in Mandarin: the left insula and right putamen showed stronger activation between rising and falling tones; the left brainstem showed weaker activation between rising and falling tones. Connectivity analysis showed that the significant projection from the laryngeal motor cortex to the brainstem which was present in rising tones was absent in falling tones. Additionally, there was a significant difference between the connection from the insula to the laryngeal motor cortex which was negative in rising tones but positive in falling tones. These results suggest that the significant projection from the laryngeal motor cortex to the brainstem used in rising tones was not active in falling tones. The connection from the left insula to the laryngeal motor cortex that differs between rising and falling tones may control whether the rise mechanism is active or not.
