Young children’s overestimation of performance: A cross-cultural comparison     

Mengtian Xia  Astrid M. G. Poorthuis  Qiang Zhou  Sander Thomaes 《Child development》2022,93(2):e207-e221

Western literature suggests that young children overestimate their performance across a range of tasks. Research in non-Western cultures, however, is lacking. In 2019, 101 Chinese (52% girls) and 98 Dutch (49% girls) children, ages 4 and 5, were asked to estimate how well they would perform on both a motor and a memory task. Children from both countries overestimated their performance to the same extent ( = .077 and .027 for the motor and memory tasks, respectively). They generally persevered in doing so despite receiving realistic performance feedback. Yet, children overestimated their peers’ performance about as much as their own performance, in some cases even more. This is the first demonstration of performance overestimation in children growing up in a non-Western culture.  相似文献   

Does adviser mentoring add value? A longitudinal study of mentoring and doctoral student outcomes   总被引：1，自引：0，他引：1  

Laura L. Paglis  Stephen G. Green  Talya N. Bauer 《Research in higher education》2006,47(4):451-476

This study of the impact of doctoral adviser mentoring on student outcomes was undertaken in response to earlier research that found (a) students with greater incoming potential received more adviser mentoring, and (b) adviser mentoring did not significantly contribute to important student outcomes, including research productivity [Green, S. G., and Bauer, T. N. (1995). Personnel Psychology 48(3): 537–561]. In this longitudinal study spanning 5 1/2 years, the effect of mentorship on the research productivity, career commitment, and self-efficacy of Ph.D. students in the ‘hard’ sciences was assessed, while controlling for indicators of ability and attitudes at program entry. Positive benefits of mentoring were found for subsequent productivity and self-efficacy. Mentoring was not significantly associated with commitment to a research career.  相似文献   

When the child gets in the news? A case study on the national written media in Turkey     

Zafer Kuş  Kadir Karatekin  Durdane Öztürk  Özlem Elvan 《Educational Media International》2016,53(2):118-138

The main purpose of this study is to analyze news stories regarding children in the national print media in the last five years using top eight newspapers in terms of circulation and evaluate these news stories based on the Convention on the Rights of the Child, which was issued by the UN and signed by Turkey. The research was undertaken as a case study. The study data were collected from top eight newspapers in terms of circulation between 2010 and 2014 in order to reveal when and how newspapers at national level represent children and the scientific content of impressions in the national media. Results show that children appear in the national media in mostly negative cases. In conclusion, it was observed in this study, children’s rights to life, development, protection, and participation were violated at both national and international levels. In this sense, news reflects the truth about “children’s rights violations”. However, the way that children appear in news and reflection in media constitute a secondary children’s rights violation.  相似文献   

Preschool Children's Judgments about Hypothetical and Actual Transgressions   总被引：1，自引：0，他引：1  

Judith G. Smetana  Naomi Schlagman  Patricia Walsh Adams 《Child development》1993,64(1):202-214

Preschoolers' ( N = 112) judgments about hypothetical and actual moral and conventional transgressions were examined. Equal numbers of boys and girls at 2 ages (3 and 4 years old) either made judgments about 8 hypothetical moral and conventional transgressions or were interviewed on the same dimensions about 8 naturally occurring moral and conventional transgressions they witnessed in their preschools. Children judged both hypothetical and actual moral transgressions to be more serious, punishable, generalizably wrong, and independent of rules and authority than conventional transgressions. Regardless of domain, hypothetical transgressions were judged to be more wrong independent of rules than actual transgressions, and hypothetical (but not actual) moral transgressions were judged to be more independent of rules than conventional transgressions. 3-year-old girls judged the wrongness of actual moral transgressions to be more independent of authority than did 3-year-old boys. Similar findings were obtained when hypothetical and actual transgressions were matched, and domain differences were still obtained when individual items were examined. Findings are discussed in terms of previous research on preschoolers' conceptions of rules and transgressions.  相似文献

Socially transmitted food preferences can be used to study long-term memory in rats     

Galef BG  Whiskin EE 《Learning & behavior》2003,31(2):160-164

Immediately after a recently fed rodentdemonstrator interacts with a conspecificobserver, the observer shows a substantially enhanced preference for whatever food its demonstrator ate. Here we show that (1) influence of a single, 30-min interaction with a demonstrator on an observer’s food preference lasts for at least 1 month, and (2) observers interacting on 2 successive days with a demonstrator fed a different diet on each day show significantly enhanced preferences for both diets a month later. Such enduring effects of single, brief interactions between a demonstrator rat and its observer provide an efficient means for studying physiological and behavioral substrates of long-term memory in rodents. Together with the results of previous studies of social influences on food choices of rats, the present results also suggest that rats may use information acquired from conspecifics to identify both toxic and safe foods for many weeks after they have acquired this information.  相似文献

Developmental trends in eating rates of normal and overweight preschool children.     

R S Drabman  G D Cordua  D Hammer  G J Jarvie  W Horton 《Child development》1979,50(1):211-216

Eating rates (bites per interval) and other meal behaviors (number of chews, sips, talks with a neighbor, and chews per bite) were observed for 30 normal and 30 overweight white preschool children in their school cafeterias. Children were classified according to weight (overweight or normal), age (1 1/2--2 years, 3--4 years, or 5--6 years) and sex. Analysis of variance revealed that overweight preschool children demonstrated a somewhat higher rate of distinctly fewer chews per bite. Boys showed increasing chew rates with increasing age. Talk rates also increased with age but were unrelated to sex or weight status. Sip rates were not significantly associated with age, sex, or weight status. These results support the hypothesis that overweight persons are characterized by an increased eating rate and show that it is apparent even around the time of first self-feeding.  相似文献   

The origins of intentional vocalizations in prelinguistic infants.     

C G Harding  R M Golinkoff 《Child development》1979,50(1):33-40

The development of the intention to communicate was examined by attempting to identify the point at which prelinguistic vocalizations are used by infants as a means of communication. This achievement was related to the infants' cognitive development. It was hypothesized that Piagetian stage 5 in the development of causality may be a prerequisite for the intentional use of vocalizations. 46 infants (X age = 10.7 months, range: 8 months--14.3 months) and their mothers were videotaped in a structured, naturalistic setting. 2 "frustration" episodes were devised to encourage communication, and the infants' vocalizations as well as other behaviors were coded by 2 observers. 2 Piagetian tasks were selected to assess the causal developmental level of the child. A significant relationship between causal developmental level and the occurrence of intentional vocalizations was found. The results support the hypothesis that stage 5 causal development may be a prerequisite to the use of intentional vocalizations.  相似文献
