La percepción del habla durante el primer año de vida

Language acquisition involves a number of complex skills that evolve in correlation with each other, thus making it possible for learners of their first spoken language —or sign language— to achieve the best results with minimal effort, as long as they do so within the appropriate period of time. In this regard, it is proposed that early speech perception has a primary role in language acquisition. In order to provide an overview of the current scientific knowledge as to the capabilities of children under the age of one to perceive spoken language, this paper presents the results of the most relevant research on discrimination of classes and types of words, interidiomatic and prosodic discrimination, phonological and phonotactic discrimination, as well as recognition of distributional regularities amongst the elements of the speech signal.     

The effectiveness of a joint mother–daughter sexual health program for Latina early adolescents

A culturally and cognitively adapted joint mother–daughter sexual health and HIV transmission curriculum was implemented for 96 Latina early adolescents and their mothers (48 mother–daughter dyads). Pretest and posttest surveys, interviews, and observations of participants' conversations about AIDS were used to assess program effectiveness in increasing knowledge and communication about sexuality and HIV transmission, and fostering daughters' positive attitudes toward using condoms in the future. At posttest, mothers and daughters reported an increase in the frequency of home communication about sexual topics and openness in general communication. Systematic observational analysis of videotaped mother–daughter conversations about AIDS revealed that, compared to the pretest, daughters were more engaged in posttest conversations as evidenced by an increase in their spontaneous sharing of information about HIV transmission and their offering of opinions. In addition, the posttest conversations focused on a broader discussion of HIV transmission risk behavior including condom use as a protective measure. Mothers who knew more about HIV transmission at posttest, and who reported more openness in general communication with daughters at posttest, asked their daughters more questions in the conversations about what they had learned in the program. Daughters who contributed more information and opinions to the posttest conversations, who were more knowledgeable about HIV transmission at posttest, and who reported more home communication about sexual topics in the posttest, also reported more positive attitudes toward using condoms in the future.     

The effects of emotion regulation strategies on positive and negative affect in early adolescents

Recent research suggests that impaired emotion regulation (ER) may play an important role in the development of youth psychopathology. However, little research has explored the effects of ER strategies on affect in early adolescents. In Study 1 (n?=?76), we examined if early adolescents are able to use distraction and whether the effects of this strategy are similar to talking to one’s mother. In Study 2 (n?=?184), we compared the effects of distraction, cognitive reappraisal, acceptance, and rumination. In both studies, participants received instructions on how to regulate their emotions after a standardised negative mood induction. In general, the results indicated that distraction, but also cognitive reappraisal and acceptance, had promising short-term effects on positive and negative affect in early adolescents. These findings suggest that targeting adaptive ER skills, such as distraction, acceptance, and cognitive reappraisal, may be an important strategy to prevent or treat psychological problems in early adolescents.     

Primary school teacher outcomes from online professional development for physical literacy: A randomised controlled trial

IntroductionPrimary (or elementary) school teachers are often relied upon to provide children with opportunities for physical literacy development; however, many of these teachers feel they lack the skills to effectively promote or ‘teach’ physical literacy. We examined the effects of an online physical literacy professional development program—relative to receiving widely-available online resources or continuing with ‘normal’ practice—on primary school teachers’ physical literacy knowledge and application.MethodsA parallel three-arm randomised controlled trial in which 92 primary school teachers were assigned to (a) an online professional development program designed to support teachers’ physical literacy instructional skills (‘intervention’), (b) receive widely-available online physical literacy resources (‘comparison’), or (c) a typical practice ‘control’ condition. Data were collected at baseline and following the four-week intervention period. The primary outcome was teachers’ physical literacy knowledge and application; secondary outcomes included teachers’ self-reported perceptions of confidence, values, and barriers. Between-group differences were assessed using the intention-to-treat principle with analysis of covariance accounting for demographic factors and baseline differences in the focal outcome.ResultsTeachers in the intervention arm scored significantly higher on post-intervention physical literacy knowledge and application than their counterparts in both the control (d = .47, p = .044) and comparison (d = 0.87, p = .007) arms. This pattern of differences was also observed for teachers’ value of physical literacy, autonomy support, and perceived personal barriers.ConclusionTo the best of our knowledge, this is the first adequately powered randomised controlled trial to demonstrate improvements in physical literacy instructional outcomes as a result of primary school teacher participation in targeted online professional development.     

Young children's comprehension of English SVO word order revisited: Testing the same children in act-out and intermodal preferential looking tasks

Act-out and intermodal preferential looking (IPL) tasks were administered to 67 English children aged 2–0, 2–9 and 3–5 to assess their comprehension of canonical SVO transitive word order with both familiar and novel verbs. Children at 3–5 and at 2–9 showed evidence of comprehending word order in both verb conditions and both tasks, although children at 2–9 performed better with familiar than with novel verbs in the act-out task. Children at 2–0 showed no evidence of comprehending word order in either task with novel verbs; with familiar verbs they showed competence in the IPL task but not in the act-out task. The difference in performance for familiar and novel verbs from the same children at 2–0, on the IPL task, and at 2–9, on the act-out task, is consistent with the hypothesis that early linguistic/cognitive representations are graded in strength, with early representations still weak and very task dependent. However, these representations also become more abstract with development, as indicated by the familiarity effect even in the more sensitive IPL task.     

Measuring executive function skills in young children in Kenya

Interest in measuring executive function skills in young children in low- and middle-income country contexts has been stymied by the lack of assessments that are both easy to deploy and scalable. This study reports on an initial effort to develop a tablet-based battery of executive function tasks, which were designed and extensively studied in the United States, for use in Kenya. Participants were 193 children, aged 3–6 years old, who attended early childhood development and education centers. The rates of individual task completion were high (65–100%), and 85% of children completed three or more tasks. Assessors indicated that 90% of all task administrations were of acceptable quality. An executive function composite score was approximately normally distributed, despite higher-than-expected floor and ceiling effects on inhibitory control tasks. Children’s simple reaction time (β = –0.20, p = .004), attention-related behaviors during testing (β = 0.24, p = .0005), and age (β = –0.24, p = .0009) were all uniquely related to performance on the executive function composite. Results are discussed as they inform efforts to develop valid and reliable measures of executive function skills among young children in developing country contexts.     

张栻早期仁学思想考

张哲学的一个核心思想是仁学 ,以《仁说》为代表。从胡宏问学以来 ,他一直关注、探索仁的问题。张仁学的发展和演变可分为两个阶段 :其一是从裒集旧编《希颜录》、编纂《洙泗言仁录》到修订《希颜录》为一段 ;其二是从争论观过知仁、以觉训仁、朱熹《仁说》到自作《仁说》为另一段。从《希颜录》起开始 ,至撰写《仁说》为止长达十四年之久 ,张一直开拓这个儒学核心观念 ,终于形成其独特的仁学思想。而且这一段时间是在张哲学的形成和发展过程中非常重要的一段时期。前一时期 ,他广泛搜集儒家典籍当中有关仁的孔子言说和颜子言行 ,然后取舍选择 ,确定次第 ,加点北宋理学家和他自己的见解而成的。其主要目的是让学者先了解“求仁之方” ,然后“自进于圣人之门墙”。后一时期 ,以讨论与论辩形式来检讨湖湘诸儒和朱熹有关仁的言说与观点 ,然后提出自己的仁学观点 ,以树立自己的仁学思想。本文集中讨论前一时期 ,即张早期仁学思想的形成和发展之历史过程及其意义。     

The interplay between early social interaction,language and executive function development in deaf and hearing infants

In this article, we review the influence of early social interaction on the development of executive function and language in infants. We first define social interaction, executive function and language and show how they are related in infant development. Studies of children born deaf are used to illustrate this connection because they represent cases where there has been a disruption to early social interaction and the development of intersubjectivity. Unlike other groups, the disturbance to development is known to be largely environmental rather than neuro-biological. This enables us to more accurately tease apart those impacts on EF that are associated with social interaction and language, since the potential confounds of disordered cognitive development are largely controlled for. The review offers a unifying model for how social, cognitive and linguistic development work together in early human development.
