Effects of word spacing on reading Chinese text from a video display terminal

This study investigated the effects of designing space between words in Chinese text, i.e., whether using a "word" instead of a "character" as a presentation unit, will facilitate the performance of reading from a video display terminal. Experimental results indicated that the main effect of word spacing significantly affected the reading time and the number of questions answered correctly. Subjects spent less time on the text with half-character word spacing or with whole-character word spacing than with conventional type (without word spacing). We also discovered that the number of questions answered correctly for stimuli with half-character spacing is significantly greater than that for stimuli with whole-character spacing, while both are smaller than for stimuli with conventional type. The additional variables, such as text difficulty and display control have significant effects as well. Our results suggested that the optimal word spacing in Chinese text should be greater than that in the traditional layout and less than a whole-character spacing. Apparently, in Chinese text, using a "word" as a presentation unit is more favorable than the traditional layouts that do not have any explicit word boundaries. The word spacing design may benefit in reading difficult or unfamiliar materials and further apply in emergency situations or in reading ambiguous sentences.     

Social regulatory effects of infant nondistress vocalization on maternal behavior

This study investigated the social regulatory function of infant nondistress vocalization in modulating maternal response. Thirteen infants and their mothers were observed weekly in a face-to-face interaction situation from 4 to 24 weeks. After the occurrences and the speech quality of infant nondistress vocalization were identified, maternal contingent responses to these vocalizations were also coded. Each responsive action was further classified by the change processes involved. Results showed that it was the occurrence of infant nondistress vocalization rather than its speech quality that regulated maternal verbal response concurrently and that infant nondistress vocalization was more likely to be synchronized with maternal facial expression and touch than with head movements. Developmentally, significant individual differences were found in the linear growth patterns of overall maternal response and within the individual modalities when responding to speechlike vocalizations.     

Can I Trust My Co-worker? Examining Correctional Officers’ Perceptions of Staff–Inmates Inappropriate Relationships within a Southern Penitentiary System

Recently, Joyce Mitchell, a correctional employee in New York, confessed to assisting two dangerous murderers in an elaborate escape attempt. While our study does not focus on correctional officers who admit to such deviant behaviors, it examines correctional officers’ perceptions of boundary violations committed by their co-workers. Using a macro-level ecological framework as our theoretical perspective, namely Sampson, Raudenbush, and Earl’s (1997) theory of collective efficacy, we surmise that organizational factors such as strong supervision and peer support can build mutual trust in prison environments where correctional officers perceive their jobs to be dangerous and stressful. Our findings have important implications for the management of correctional facilities as well as for the contemporary development and significance of the theory of collective efficacy.     

An Investigation of Entrepreneurs' Venture Persistence Decision: The Contingency Effect of Psychological Ownership and Adversity

We incorporate psychological ownership theory and adversity literature to examine the joint effect of psychological ownership and adversity on entrepreneurs' persistence decision. The results of two experiments and one survey show that both low adversity and high psychological ownership for the venture increase entrepreneurs' likelihood of persistence. We also identify the moderating effect of adversity. Psychological ownership is more relevant to the likelihood of persistence when adversity is high than when it is low. Our research contributes to psychological ownership theory and the entrepreneurial persistence literature and has practical implications for entrepreneurs.     

SCIENCE AND CONFUCIANISM IN RETROSPECT AND PROSPECT

In contrast to Western science and religion, a topic which has been studied very much since the twentieth century, less research has been done on science and Confucianism. By way of a comparative viewpoint within the history of science, this article will deal with some aspects of science and Confucianism in retrospect, for instance, the Confucian origin of the idea of tian yuan di fang 天圓地方, the natural philosophy of qi, and the wu xing li tian zhi qi 五行沴天之氣 bringing abnormal astrological phenomena and reflecting a negative Confucian relation between politics, ethics, and nature. In the late Ming, Xiong Mingyu found that abnormal astrological phenomena, as atmospheric events, happened in the sublunar region rather than in the stars, and in the present time we can reinterpret the crisis of air pollution or global climate change as reflecting a negative Confucian relation between politics, ethics, and nature and as a warning of collective misbehavior in our use of modern scientific technologies.     

Infant vocal development during the first 6 months: speech quality and melodic complexity

The early development of infant non‐distress vocalizations was investigated in this study. Thirteen infants, from 4 to 24 weeks of age, and their mothers were observed weekly in a face‐to‐face interaction situation. The speech quality (syllabic versus vocalic) and melodic complexity (simple versus complex) of infant vocalizations were coded independently. Based on speech quality and melodic complexity, four types of infant non‐distress vocalizations were categorized: simple and complex syllabic (speech‐like) vocalizations as well as simple and complex vocalic (non‐speech‐like) vocalizations. Results showed that complex syllabic sounds were of longer duration and complex vocalic sounds were less frequent than the other types of vocalizations. Curvilinear developmental trends were found in the rate of simple vocalic sounds and in the mean duration of complex syllabic sounds. Furthermore, before 4 months of age, vocalic sounds were more likely to be associated with simple melodic contours, after which syllabic sounds were more likely to be associated with complex melodic contours. A dynamic systems perspective on the early development of infant vocalization is discussed. Copyright © 2000 John Wiley & Sons, Ltd.     

Functional MRI of conventional and anomalous metaphors in Mandarin Chinese

This study looks at whether conventional and anomalous metaphors are processed in different locations in the brain while being read when compared with a literal condition in Mandarin Chinese. We find that conventional metaphors differ from the literal condition with a slight amount of increased activation in the right inferior temporal gyrus. In addition, when the anomalous metaphor condition is compared with the literal condition, increased activation occurs bilaterally in the frontal and temporal gyri. Lastly, the comparison between the anomalous and conventional metaphor conditions shows bilateral activation in the middle frontal gyrus and the precentral gyrus, and right-hemisphere activation in the superior frontal gyrus. Left hemisphere activation is found in the inferior frontal gyrus and fusiform gyrus. The left hemisphere activation in the frontal and temporal gyri point to the recruitment of traditional language-based areas for anomalous metaphor sentences, while the right-hemisphere activation found suggests that remote associations are being formed. In short, our study supports the idea that metaphors are not a homogenous type of figurative language and that distinguishing between different types of metaphors will advance theories of language comprehension.     

The Wick in the Candle of Learning: Epistemic Curiosity Activates Reward Circuitry and Enhances Memory

ABSTRACT— Curiosity has been described as a desire for learning and knowledge, but its underlying mechanisms are not well understood. We scanned subjects with functional magnetic resonance imaging while they read trivia questions. The level of curiosity when reading questions was correlated with activity in caudate regions previously suggested to be involved in anticipated reward. This finding led to a behavioral study, which showed that subjects spent more scarce resources (either limited tokens or waiting time) to find out answers when they were more curious. The functional imaging also showed that curiosity increased activity in memory areas when subjects guessed incorrectly, which suggests that curiosity may enhance memory for surprising new information. This prediction about memory enhancement was confirmed in a behavioral study: Higher curiosity in an initial session was correlated with better recall of surprising answers 1 to 2 weeks later.     

Sequential effects in facial expression categorization

Facial expressions are highly dynamic signals that are rarely categorized as static, isolated displays. However, the role of sequential context in facial expression categorization is poorly understood. This study examines the fine temporal structure of expression-based categorization on a trial-to-trial basis as participants categorized a sequence of facial expressions. The results showed that the local sequential context provided by preceding facial expressions could bias the categorical judgments of current facial expressions. Two types of categorization biases were found: (a) Assimilation effects-current expressions were categorized as close to the category of the preceding expressions, and (b) contrast effects-current expressions were categorized as away from the category of the preceding expressions. The effects of such categorization biases were modulated by the relative distance between the preceding and current expressions, as well as by the different experimental contexts, possibly including the factors of face identity and the range effect. Thus, the present study suggests that facial expression categorization is not a static process. Rather, the temporal relation between the preceding and current expressions could inform categorization, revealing a more dynamic and adaptive aspect of facial expression processing.
