Visual and phonological coding in working memory and orthographic skills of deaf children using Chilean sign language     

Alvarado JM  Puente A  Herrera V 《American annals of the deaf》2008,152(5):467-479

Deaf children can improve their reading skills by learning to use alternative, visual codes such as fingerspelling. A sample of 28 deaf children between the ages of 7 and 16 years was used as an experimental group and another sample of 15 hearing children of similar age and academic level as a control group. Two experiments were carried out to study the possible interactions between phonological and visual codes and working memory, and to understand the relationships between these codes and reading and orthographic achievement. The results highlight the relationship between dactylic and orthographic coding. Just as phoneme-to-grapheme knowledge can facilitate reading for hearing children, fingerspelling-to-grapheme knowledge has the potential to play a similar role for deaf readers.  相似文献   

Play in two societies: pervasiveness of process, specificity of structure     

Bornstein MH  Haynes OM  Pascual L  Painter KM  Galperín C 《Child development》1999,70(2):317-331

The present study compared Argentine (N = 39) and U.S. (N = 43) children and their mothers on exploratory, symbolic, and social play and interaction when children were 20 months of age. Patterns of cultural similarity and difference emerged. In both cultures, boys engaged in more exploratory play than girls, and girls engaged in more symbolic play than boys; mothers of boys engaged in more exploratory play than mothers of girls, and mothers of girls engaged in more symbolic play than mothers of boys. Moreover, in both cultures, individual variation in children's exploratory and symbolic play was specifically associated with individual variation in mothers' exploratory and symbolic play, respectively. Between cultures, U.S. children and their mothers engaged in more exploratory play, whereas Argentine children and their mothers engaged in more symbolic play. Moreover, Argentine mothers exceeded U.S. mothers in social play and verbal praise of their children. During an early period of mental and social growth, general developmental processes in play may be pervasive, but dyadic and cultural structures are apparently specific. Overall, Argentine and U.S. dyads utilized different modes of exploration, representation, and interaction--emphasizing "other-directed" acts of pretense versus "functional" and "combinatorial" exploration, for example--and these individual and dyadic allocentric versus idiocentric stresses accord with larger cultural concerns of collectivism versus individualism in the two societies.  相似文献

Some cultural and economic factors leading to neglect, abuse and violence in respect of children within the family in Sri Lanka     

Wimala de Silva Ph.D. 《Child abuse & neglect》1981,5(4):391-405

The paper provides an overview of the present position. It attempts to identify the causational factors in situations of child neglect, abuse and violence and to pinpoint areas where there is a lacuna in information and knowledge. The study takes prevalence of abandoned children, failure to meet a child's basic needs and underutilization of services provided free by the state as indices of neglect. Measured in these terms it seems that though in Sri Lanka children are considered a blessing, yet they are also subject to neglect though this is not deliberate on the part of parents but arising from numerous factors, mainly poverty and ignorance. Other influences also operate such as cultural values and weaknesses in the delivery systems. Today females of all socioeconomic levels seek employment, both locally and abroad. This can lead to child neglect since community services for child care are inadequate and traditional help is dwindling. The negative impact on children of certain aspects of modernization is also considered. Abuse of children manifests itself mainly in child domestic labour and the exploitation, particularly of malformed and diseased children, in the trade of begging. Violence as judged by reported cases is minimal. But considering social attitudes regarding physical punishment, its prevalence may be wider than generally believed. The need for statistics and studies on all aspects of child care and child behaviour have come out in the study.  相似文献

Intergenerational educational and occupational mobility in Spain: does gender matter?     

Laura De Pablos Escobar  María Gil Izquierdo 《British Journal of Sociology of Education》2016,37(5):721-742

This paper explores the changes in intergenerational mobility seen in Spain during the last century. It examines educational and occupational mobility, paying particular attention to the existence of a differentiated gender effect. The magnitude of the historical changes that have taken place in Spain during the twentieth century and the scarcity of studies in this field increase the value of this paper. More specifically, the paper seeks to describe how the situation has changed with the social–economic and education policy developments in democratic Spain, especially with regards to women. The main results show that while educational mobility has improved, there has been no such significant change in occupational mobility.  相似文献   

Significant learning in catholic religious education: the case of Temuco (Chile)     

Jessica Navarrete  Angélica Vásquez  Efraín Montero  Daniel Cantero 《British Journal of Religious Education》2020,42(1):90-102

ABSTRACT

The object of this article is to reveal the teaching strategies used by teachers for religious education in Temuco, Chile. The paradigm used was qualitative and the design was a single interpretative case study. The data were collected by semi-structured interviews with pupils and religious education (RE) teachers. The results show convergences of successful strategies, such as the use of conversations to form opinions related with the pupils’ everyday interests. We conclude that significant learning for catholic religious education in schools (CRES) includes teaching strategies associated with individual and collective reflections and conversations on topical social issues. Thus, religious education may enable us to advance towards a pluralist approach to the teaching of religion.  相似文献   

Temporal discounting of aversive consequences in rats     

William Rodríguez  Arturo Bouzas  Vladimir Orduña 《Learning & behavior》2018,46(1):38-48

Previous research has extensively evaluated the impact of delay on the value of positive reinforcers, but the study of its impact on the value of aversive consequences is scarce. The present study employed a modification of Evenden and Ryan’s procedure (1996, Psychopharmacology, 128(2), 161–170) to obtain data on temporal discounting of an aversive consequence, with rats as experimental subjects. In the first phase of the procedure, rats chose between one-pellet and four-pellet alternatives; when subjects developed preference for the larger-amount alternative, a shock was added to it, resulting in a loss of preference. In the first experimental condition, the delay to shock was progressively increased within each session from zero to 40 s (ascending delays), which resulted in a recovery of the preference for the larger-amount + shock alternative as the delay to shock was increased. In a subsequent condition (descending delays) the delay to shock was progressively decreased within each session, from 40 to 0 s. In both conditions, the preference for the smaller-amount no-shock alternative was well described by a hyperbolic function. The order of presentation of the delays within the session, ascending or descending, did not alter the relationship between preference and delay to shock. The temporal discounting curve obtained in the present study could represent a baseline for analyzing the impact that diverse environmental and pharmacological variables have on the temporal discounting of aversive consequences.  相似文献   

The Impact of Early Social Interactions on Later Language Development in Spanish–English Bilingual Infants          下载免费PDF全文

Nairán Ramírez‐Esparza  Adrián García‐Sierra  Patricia K. Kuhl 《Child development》2017,88(4):1216-1234

This study tested the impact of child‐directed language input on language development in Spanish–English bilingual infants (N = 25, 11‐ and 14‐month‐olds from the Seattle metropolitan area), across languages and independently for each language, controlling for socioeconomic status. Language input was characterized by social interaction variables, defined in terms of speech style (“parentese” vs. standard speech) and social context (one‐on‐one vs. group). Correlations between parentese one‐on‐one and productive vocabulary at 24 months (n = 18) were found across languages and in each language independently. Differences are highlighted between previously published monolingual samples, which used the same methods as the current study of bilingual infants. The results also suggest cultural effects on language input and language development in bilingual and bicultural infants.  相似文献   

Validation of clay modeling as a learning tool for the periventricular structures of the human brain          下载免费PDF全文

Visualizing anatomical structures and functional processes in three dimensions (3D) are important skills for medical students. However, contemplating 3D structures mentally and interpreting biomedical images can be challenging. This study examines the impact of a new pedagogical approach to teaching neuroanatomy, specifically how building a 3D‐model from oil‐based modeling clay affects learners’ understanding of periventricular structures of the brain among undergraduate medical students in Colombia. Students were provided with an instructional video before building the models of the structures, and thereafter took a computer‐based quiz. They then brought their clay models to class where they answered questions about the structures via interactive response cards. Their knowledge of periventricular structures was assessed with a paper‐based quiz. Afterward, a focus group was conducted and a survey was distributed to understand students’ perceptions of the activity, as well as the impact of the intervention on their understanding of anatomical structures in 3D. Quiz scores of students that constructed the models were significantly higher than those taught the material in a more traditional manner (P < 0.05). Moreover, the modeling activity reduced time spent studying the topic and increased understanding of spatial relationships between structures in the brain. The results demonstrated a significant difference between genders in their self‐perception of their ability to contemplate and rotate structures mentally (P < 0.05). The study demonstrated that the construction of 3D clay models in combination with autonomous learning activities was a valuable and efficient learning tool in the anatomy course, and that additional models could be designed to promote deeper learning of other neuroanatomy topics.
