中文词汇加工过程中的无关言语效应

通过两个词汇识别任务,考察词汇加工过程中的无关言语效应。实验1采用真假词判断任务,考察有意义言语、无意义言语、白噪音和安静的背景声音对不同具体性的词汇识别的影响。结果发现,仅有意义言语干扰了词汇识别,且主要体现在对低具体性词汇判断的反应时显著增加。实验2采用了语义范畴判断任务,同样发现有意义言语条件下被试的反应时显著大于其他声音条件。结果表明,中文词汇加工过程中存在无关言语效应,且当任务强调语义加工时,干扰主要源于无关言语的语义成分,支持了语义干扰假说。     

Perception of audiovisual infant directed speech

Infant perception often deals with audiovisual speech input and a first step in processing this input is to perceive both visual and auditory information. The speech directed to infants has special characteristics and may enhance visual aspects of speech. The current study was designed to explore the impact of visual enhancement in infant-directed speech (IDS) on audiovisual mismatch detection in a naturalistic setting. Twenty infants participated in an experiment with a visual fixation task conducted in participants’ homes. Stimuli consisted of IDS and adult-directed speech (ADS) syllables with a plosive and the vowel /a:/, /i:/ or /u:/. These were either audiovisually congruent or incongruent. Infants looked longer at incongruent than congruent syllables and longer at IDS than ADS syllables, indicating that IDS and incongruent stimuli contain cues that can make audiovisual perception challenging and thereby attract infants’ gaze.     

Sensitive Caregiving Fosters the Comprehension of Speech: When Gestures Speak Louder than Words

Despite a variety of theoretical arguments to the contrary, sensitive caregiving makes an important contribution to the comprehension and emergence of speech. This research, informed by social ecological realism, documented that during the prelinguistic and one-word periods, caregivers routinely provided additional perceptual structure to their infants following communicative breakdowns. This sensitive adjusting of subsequent messages to infants contributed significantly to reaching a common understanding. Caregivers also modified their verbal messages in subsequent turns by making them more specific. In contrast, however, these elaborations did not contribute to achieving a practical consensus regarding ongoing events. These results suggest that the social ecological realist approach informing this research has important implications for theory, reviewing past empirical findings and future research. © 1996 John Wiley & Sons, Ltd.     

Parametrically Dissociating Speech and Nonspeech Perception in the Brain Using fMRI

Candidate brain regions constituting a neural network for preattentive phonetic perception were identified with fMRI and multivariate multiple regression of imaging data. Stimuli contrasted along speech/nonspeech, acoustic, or phonetic complexity (three levels each) and natural/synthetic dimensions. Seven distributed brain regions' activity correlated with speech and speech complexity dimensions, including five left-sided foci [posterior superior temporal gyrus (STG), angular gyrus, ventral occipitotemporal cortex, inferior/posterior supramarginal gyrus, and middle frontal gyrus (MFG)] and two right-sided foci (posterior STG and anterior insula). Only the left MFG discriminated natural and synthetic speech. The data also supported a parallel rather than serial model of auditory speech and nonspeech perception.     

Loneliness and Dread as Time Sense Disturbances

Our consciousness of time is created by our longing over duration for the care of a nurturing other. By means of a case study, it is shown here that the experience of abject loneliness is dependent upon a disturbed consciousness of time: unmet needs over the passage of time. Loneliness as such is the denial of the present moment—its possibilities and its demands. The loss of the present moment fosters a disturbed judgment of time: the sense that the present moment has stopped—is virtually endless, since the present moment has no future toward which to intend. This time disturbance diminishes the subject's capacity for agency.     

后基因组时代的医学发展

1990年,美国正式启动“人类基因组计划”。随着这项工程成果的不断取得,人类即将进入利用、使用“人类基因组计划”成果的“后基因组时代”。在这个时代,基因芯片和基因工程技术将被广泛地使用在医学科学中,给医学科学的发展带来一场深刻的革命。同时医学科学也将面临着前所未有的冲突和抉择。充分认识这些问题,对寻求现实医学科学的发展途径具有重要的启示意义。     

言语产生中的词汇通达理论

首先简单介绍了言语产生中词汇产生研究方法,然后重点介绍了言语产生中的2类重要的词汇通达理论：交互激活理论和独立阶段理论,围绕词汇通达中的3个重要问题：词汇通达的阶段、词汇通达的时间进程、词汇通达阶段是分离独立的还是交互作用的展开论述,阐述了2类理论的相同点和相异点。     

The general causality orientations scale: Self-determination in personality

This paper describes the development and validation of a general causality orientations scale. Causality orientations are conceptualized as relatively enduring aspects of people that characterize the source of initiation and regulation, and thus the degree of self-determination, of their behavior. Three orientations—autonomy, control, and impersonal—are measured by the three subscales of the instrument. Individuals are given a score on each orientation, thus allowing the use of the theoretically appropriate subscale (or, in some cases, a combination of subscales) to predict affects, cognitions, and behaviors. The scale was shown to have internal consistency and temporal stability. The orientations were shown to fit appropriately into a nomological network of constructs and to relate to various behaviors that were hypothesized to be theoretically relevant.     

Rationale for a pragma-dialectical perspective

Starting from a concept of reasonableness as well-consideredness, it is discussed in what way science could serve as a model for reasonable argumentation. It turns out that in order to be reasonable two requirements have to be fulfilled. The argumentation should comply with rules which are both problem-valid and intersubjectively valid. Geometrical and anthropological perspectives don't meet these criteria, but a critical perspective does. It is explained that a pragma-dialectical approach to argumentation which agrees with this critical perspective is indeed problem-valid and that strong pragmatic and utilitarian arguments can be given for its intersubjective validity. Thus, conventional validity is promoted for a code of conduct for discussants who want to resolve their disputes reasonably by way of a critical discussion.
