Making Sense of Number Words and Arabic Digits: Does Order Count More?     

Francesco Sella  Daniela Lucangeli  Roi Cohen Kadosh  Marco Zorzi 《Child development》2020,91(5):1456-1470

The ability to choose the larger between two numbers reflects a mature understanding of the magnitude associated with numerical symbols. The present study explores how the knowledge of the number sequence and memory capacity (verbal and visuospatial) relate to number comparison skills while controlling for cardinal knowledge. Preschool children’s (N = 140, M_{age-in-months} = 58.9, range = 41–75) knowledge of the directional property of the counting list as well as the spatial mapping of digits on the visual line were assessed. The ability to order digits on the visual line mediated the relation between memory capacity and number comparison skills while controlling for cardinal knowledge. Beyond cardinality, the knowledge of the (spatial) order of numbers marks the understanding of the magnitude associated with numbers.  相似文献   

The Transition to Reaching: Mapping Intention and Intrinsic Dynamics   总被引：9，自引：0，他引：9

The onset of directed reaching demarks the emergence of a qualitatively new skill. In this study we asked how intentional reaching arises from infants' ongoing, intrinsic movement dynamics, and how first reaches become successively adapted to the task. We observed 4 infants weekly in a standard reaching task and identified the week of first arm-extended reach, and the 2 weeks before and after onset. The infants first reached at ages ranging from 12 to 22 weeks, and they used different strategies to get the toy. 2 infants, whose spontaneous movements were large and vigorous, damped down their fast, forceful movements. The 2 quieter infants generated faster and more energetic movements to lift their arms. The infants modulated reaches in task-appropriate ways in the weeks following onset. Reaching emerges when infants can intentionally adjust the force and compliance of the arm, often using muscle coactivation. These results suggest that the infant central nervous system does not contain programs that detail hand trajectory, joint coordination, and muscle activation patterns. Rather, these patterns are the consequences of the natural dynamics of the system and the active exploration of the match between those dynamics and the task.  相似文献   

Zoo educators face common and specific demands and resources: an application of the JD-R model     

Daniela Sellmann  Valerie Beckmann  Sarah Panzlaff  Susanne Menzel 《Environmental Education Research》2019,25(1):92-114

Zoo educators are important communicators of the targets in education for sustainable development and therefore carry great responsibility for global environmental change. However, German zoo educators form a heterogeneous group, many of them working in non-permanent job positions and facing multiple challenges at work. Applying the job demands-resources model, our study aims at revealing factors influencing zoo educators’ job strain. Our data from eight in-depth interviews with German zoo educators confirm that they perceive common factors known from other studies, such as demands (e.g. workload) and resources (e.g. supervisory support). Besides this, job-specific factors were identified (e.g. working with humans and animals). The demands zoo educators mentioned could be classified either as job hindrances (e.g. lack of equipment) or job challenges (e.g. learning). Future studies should quantify these results to facilitate the development of appropriate measures to reduce educators’ job strain, thus enhancing their performance.  相似文献   

Family Risk and Externalizing Problems in Chilean Children: Mediation by Harsh Parenting and Emotional Support     

Elisa Ugarte  Marigen Narea  Daniela Aldoney  David G. Weissman  Paul D. Hastings 《Child development》2021,92(3):871-888

Latent class analysis and multigroup mediation were used with 8,860 families in Chile to identify risk groups varying in socioeconomic status, family structure, and maternal depression, to determine whether profiles differed in children’s development of externalizing problems (EP) from 35 to 61 months, and maternal parenting that predicted EP. Four groups were identified: one no-risk profile and three risk profiles, impoverished and undereducated, depressed and impoverished, and father-absent and impoverished. All classes differed in EP. Maternal emotional support and harsh parenting were differentially associated with the development of EP across the three risk groups, relative to the low-risk group. Thus, specific constellations of adversities differentially predicted children’s EP and socialization processes mediating links between risk and EP. Implications are discussed.  相似文献   

Empowering visuo-spatial ability in primary school: results from a follow-up study     

Maria Chiara Fastame  Daniela Callai 《Educational Psychology in Practice》2015,31(1):86-98

The current study was primarily aimed at verifying the effect of a combined computer-assisted and pencil-and-paper training that was developed to empower visuo-spatial abilities in primary school pupils. One hundred and twenty third grade (mean average: eight years old) and fourth grade (mean age: nine years old) students attending several Italian primary schools were presented with several tests of the Primary Mental Abilities (PMA) battery by Thurstone and Thurstone. Of these, 64 children underwent the training “Recovery in visuo-spatial abilities” developed by Fastame and Antonini for 15 weekly sessions. The remaining students were assigned to the control group. Post-test scores and a follow-up assessment after six months by the end of the training highlight the positive impact of the intervention in enhancing visuo-spatial abilities.  相似文献

Two-Year-Old Children's Sensitivity to a Parent's Knowledge State When Making Requests     

Daniela K. O'Neill 《Child development》1996,67(2):659-677

These studies examined whether toddlers take their communicative partners' knowledge states into account when communicating with them. In Study 1 , 16 2-year-old children (mean age 2-7) had to ask a parent for help in retrieving a toy. On each trial, a child was first introduced to a new toy that was then placed in 1 of 2 containers on a high shelf. The parent either witnessed these events along with the child or did not because she or he had left the room or had covered her or his eyes and ears. As predicted, when asking for help in retrieving the toy, children significantly more often named the toy, named its location, and gestured to its location when a parent had not witnessed these events than when she or he had. In Study 2, 16 2-year-old children (mean age 2-3) had to ask a parent for help in retrieving a sticker dropped into 1 of 2 identical containers placed out of reach in the far corners of a table. The parent either witnessed, along with the child, which container the sticker was dropped into or did not because her or his eyes were closed. In their requests for help, young 2-year-old children gestured to the sticker's location significantly more often when the parent did not know its location than when she or he did. The implications of these findings for current characterizations of 2-year-old children's ability to assess the knowledge of others is discussed.  相似文献   

‘Family comes in all forms,blood or not’: disrupting dominant narratives around the patriarchal nuclear family     

Daniela Gachago  Lindsay Clowes  Janet Condy 《Gender and education》2018,30(8):966-981

ABSTRACT

After nearly 25 years of democracy, lives of young South Africans are still profoundly shaped by the legacies of apartheid. This paper considers how these differences are produced, maintained and disrupted through an exploration of changing narratives developed by a small group of South African pre-service teachers, with a particular focus on the narratives developed around discourses of fatherhood generally and absent fathers in particular. We draw on interviews conducted with three students in which we discussed their digital stories and literature reviews. In this paper, we draw attention to the limitations of digital storytelling and the risks such autobiographical storytelling presents of perpetuating dominant narratives that maintain and reproduce historical inequalities. At the same time, in highlighting ways in which this risk might be confronted, the paper also aims to show the possibilities in which these dominant narratives may be challenged.  相似文献
