PurposeThe aim of this study was to examine the relationship between frequency of gesture use and language with a consideration for the effect of age and setting on frequency of gesture use in prelinguistic typically developing children.MethodParticipants included a total of 54 typically developing infants and toddlers between the ages of 9 months and 15 months separated into two age ranges, 9-12 months and 12-15 months. All participants were administered the Mullen’s Scale of Early Learning and two gesture samples were obtained: one sample in a structured setting and the other in an unstructured setting. Gesture samples were coded by research assistants blind to the purpose of the research study and total frequency and frequencies for the following gesture types were calculated: behavior regulation, social interaction, and joint attention (Bruner, 1983).ResultsResults indicated that both age and setting have a significant effect on frequency of gesture use and frequency of gesture is correlated to receptive and expressive language abilities; however, these relationships are dependent upon the gesture type examined.ConclusionsThese findings further our understanding of the relationship between gesture use and language and support the concept that frequency of gesture is related to language abilities. This is meaningful because gestures are one of the first forms of intentional communication, allowing for early identification of language abilities at a young age.  相似文献

There is increasing interest in the relation between screen use and sleep problems in early childhood. In a sample of 30-month-old children, this study used observational measures of screen use during the hour or so leading up to bedtime, parent reports of screen use during the child’s bedtime routine, and actigraphic measures of toddler sleep to complement parent-reported sleep problems. Whether screen use was observed during the pre-bedtime period or was reported by the parents as part of the nightly bedtime routine, greater screen use in either context was associated with more parent-reported sleep problems. Additionally, more frequent parent-reported screen use during the bedtime routine was also associated with actigraphic measures of later sleep, shorter sleep, and more night-to-night variability in duration and timing of sleep. These associations suggest the negative consequences of screen use for children’s sleep extend both to aspects of sleep reported by parents (e.g., bedtime resistance, signaled awakenings) and to aspects measured by actigraphy (e.g., shorter and more variable sleep).  相似文献

语言使用模式能反映心理状态和精神病理学特征。抑郁症患者与健康人群的语言使用模式存在差异, 识别抑郁症患者的语言使用模式有助于抑郁症的预测和诊断。传统的心理学研究和基于社交媒体的研究均表明, 抑郁症患者更多地使用第一人称单数代词和消极情绪词, 更少地使用第一人称复数代词和积极情绪词。基于社交媒体的研究进一步发现了一些抑郁个体日常生活中的其他语言标志。建议未来的研究进一步确认更具抑郁特异性的语言标志, 并进一步探索语言标志与抑郁症状间的理论联系。  相似文献

The purpose of this article is to explain the Mohists’ perceived inconsistences of the following three propositions in the Mojing since we attribute to them an unconditional love toward human beings: (A) A thief is a man. Killing a thief is not killing men. (B) A thief is a man. Loving a thief is not loving men. (C) Zang is a man. Loving Zang is loving men. The attribution of unconditional love toward human beings is not unusual to the Mohists when we render the Mohist idea of jian’ai as universal love. My interpretation first suggests that we can consistently interpret the Mohist ethical position as intentional utilitarianism. Second, I claim that Mohist universal love includes some generality, though it does not have to mean universality without exception. This Mohist generality will be explained through the generic use of nouns.  相似文献

Photo-elicitation is a qualitative interview technique where researchers solicit responses, reactions, and insights from participants by using photographs or other images as stimuli. Images can be researcher-generated or participant-generated and each has particular benefits and challenges. Though not new, the use of images within criminology is an underused technique. In this paper we advocate the use of photo-elicitation techniques suggesting that they offer a powerful addition to standard data collection and presentation techniques. In making our case, we draw on our experiences from an 18-month long photo-ethnography of people living in rural Alabama who use methamphetamine. The ethnography consisted of formal interviews and informal observations with 52 participants and photography of 29 of them. While we draw on our overall experiences from the project we focus specifically on the photographs generated by, and taken of, one key participant—Alice. We demonstrate the benefits and challenges of using photo elicitation interviews with vulnerable individuals such as Alice, by considering themes such as representation, empowerment and emotionality. Additionally, we highlight the practical and ethical issues that confront researchers who incorporate the visual into their research.  相似文献

Impaired tool related action in ideomotor apraxia is normally ascribed to loss of sensorimotor memories for habitual actions (engrams), but this account has not been tested against a hypothesis of a general deficit in representation of hand-object spatial relationships. Rapid reaching for familiar tools was compared with reaching for abstract objects in apraxic patients (N = 9) and in a control group with right hemisphere posterior stroke. The apraxic patients alone showed an impairment in rotating the wrist to correctly grasp an inverted tool but not when inverting the hand to avoid a barrier and grasp an abstract object, and the severity of the impairment in tool reaching correlated with pantomime of tool-use. A second experiment with two apraxic patients tested whether barrier avoidance was simply less spatially demanding than reaching for a tool. However, the patient with damage limited to the inferior parietal lobe still showed a selective problem for tools. These results demonstrate that some apraxic patients are selectively impaired in their interaction with familiar tools, and this cannot be explained by the demands of the task on postural or spatial representation. However, traditional engram theory cannot account for associated problems with imitation of novel actions nor the absence of any correlated deficit in recognition of the methods of grasp of common tools. A revised theory is presented which follows the dorsal and ventral streams model ( Milner & Goodale, 2008) and proposes preservation of motor control by the dorsal stream but impaired modulating input to it from the conceptual systems of the left temporal lobe.  相似文献

Historically, research demonstrates that mothers’ attitudes and characteristics of their parenting are intertwined. More recently, mothers’ perceptions of their children are becoming a new focus of interest. To further understand the relationships among mothers’ perceptions of their young children, their parenting behaviors, and their ratings of their young children's behavior problems, this study examines the ratings of a diverse group of mothers who have young children. Correlational results of this study demonstrate that these variables are related in the anticipated directions. Further, results of regression analyses suggest that mothers’ positive and negative perceptions of their young children and their use of limit setting are important in predicting children's behavior problems. These findings suggest that interventions focusing on changing mothers’ perceptions of their young children as well as their parenting behaviors may be related to decreases in young children's behavior problems.  相似文献

Objective: Previous research has focused mostly on abstainer and/or general drinker prototypes. The present studies examined an abstainer, moderate drinker and heavy drinker prototype in relation to drinking behaviour.

Design: Two studies among young adults aged 18–25 (paper-and-pencil, cross-sectional, N?=?140; online, prospective, N?=?451) assessed prototype favourability and participants’ perceived similarity to the prototypes. Participants were also categorised into abstainers, moderate, and heavy drinkers.

Results: Similarity and favourability had similar sequences in both studies: the moderate drinker and abstainer prototypes were evaluated most favourable and felt similar to; the heavy drinker prototype was rated the least favourable and felt similar to. Importantly, heavy drinking participants felt most similar to the moderate drinker prototype and rated the heavy drinker least desirable. The results suggest a need for research to include other prototypes, such as the moderate drinker, besides the abstainer and heavy drinker.

Conclusion: The studies provide insights into the contribution of alternative prototypes (i.e. moderate drinker) into the relationship between prototype perceptions and drinking behaviour. The results suggest tailoring prototype-based interventions according to drinking behaviour. Importantly, realistic perceived similarity to the more favourable moderate drinker prototype may therefore need to be encouraged only after appropriate reductions in heavy drinkers’ alcohol consumption.  相似文献
