Maternal still face is a robust experimental procedure designed to examine infants’ sensitivity to social contingency and reactivity to its violation. To extend earlier research on the still-face effect on term infants in Western cultures, the present study compared Taiwanese term and preterm infants’ attention and affective response to and recovery from a modified maternal still-face procedure that used an additional still-face reengagement sequence at 2 months of age (corrected age for preterm infants). Infants’ gaze and facial affect were coded from videos. Results showed that preterm infants were as sensitive as term infants to the interruption to social contingency. Both groups of infants reacted with decreased gaze and positive affect across episodes, together with a decreased latency to gaze aversion and an increased latency to positive affect. Both term and preterm infants also demonstrated a W-shaped pattern of decline-followed-by-recovery in their latency to negative affect. However, compared to term infants, preterm infants became distressed faster and stayed in a negative affective state longer after the first exposure to maternal still face. Effects of prematurity on infant attention and affect regulation were discussed. Implications of preterm infants’ heightened affective negativity to mild stress for intervention studies were also addressed. 相似文献

Most research based on Fitts' law define a log-linear relationship between temporal and spatial accuracy in goal-directed aiming tasks using stationary targets. Whether this relationship holds or not when the targets have varying velocities, and how the behavioral strategies and physical activities may change accordingly are of interest. The aim of this study was to investigate the relationship between temporal and spatial accuracy in goal-directed aiming tasks with moving targets. Participants were asked to aim at two target widths using a joystick. Results demonstrated that in a goal-directed aiming task there was a negative effect on performance when target velocity was increased or target width was decreased. Participants moved faster and then made more systematic errors in a high-velocity target condition. Results may be applicable to the complex perceptual-motor behavior of people who perform tasks using computers. 相似文献

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. 相似文献

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. 相似文献

An Investigation of Entrepreneurs' Venture Persistence Decision: The Contingency Effect of Psychological Ownership and Adversity 下载免费PDF全文
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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

Although direct observation has provided much information regarding caregiver-care recipient interactions, our understanding of the applications of this technique remains incomplete. This study expands upon earlier observational work by examining adults with mental retardation (MR) and their family caregivers in the home setting. Specialized computer software was used to conduct real-time observation and recording of interactional styles of maternal caregivers of eight younger (M = 23 years old) and eight older (M = 49 years old) MR adults during two cognitive tasks: block design and card sorting. Differences in the amount and type of assistance provided by the caregiver were examined by coding the occurrence and duration of seven interactional behaviors. The results demonstrated that the caregivers of the younger adults used more positive statements and modeling/gestural prompts, whereas the caregivers of the older adults provided more physical assistance and performed more of the tasks themselves. More importantly, this project provided information regarding interactions between MR adults and their maternal caregivers and demonstrated the utility of computer-assisted data collection technology with a community-based, nondemented population. 相似文献

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. 相似文献
