Flavor-evaluative conditioning is unaffected by contingency knowledge during training with color-flavor compounds     

Dickinson A  Brown KJ 《Learning & behavior》2007,35(1):36-42

In two experiments, participants inspected and drank a series of drinks, half of which contained sugar and half unpalatable Tween20 (tween). Each sugar and tween drink had a particular flavor and color. Following this training, the flavors of the sugar drinks were assigned higher hedonic evaluations than were those of the tween drinks, even though the participants did not reliably report which flavors had been present in the sugar and tween drinks during training. Moreover, the evaluative conditioning of the flavors was unaffected by whether or not the colors alone had been pretrained to predict the presence of sugar or tween in the drinks. In accord with Baeyens, Eelen, van den Bergh, and Crombez (1990), we conclude that flavor-evaluative conditioning is not mediated by contingency learning.  相似文献   

Phenomenal permanence and the development of predictive tracking in infancy     

Bertenthal BI  Longo MR  Kenny S 《Child development》2007,78(1):350-363

The perceived spatiotemporal continuity of objects depends on the way they appear and disappear as they move in the spatial layout. This study investigated whether infants' predictive tracking of a briefly occluded object is sensitive to the manner by which the object disappears and reappears. Five-, 7-, and 9-month-old infants were shown a ball rolling across a visual scene and briefly disappearing via kinetic occlusion, instantaneous disappearance, implosion, or virtual occlusion. Three different measures converged to show that predictive tracking increased with age and that infants were most likely to anticipate the reappearance of the ball following kinetic occlusion. These results suggest that infants' knowledge of the permanence and nonpermanence of objects is embodied in their predictive tracking.  相似文献   

Relation between reading problems and internalizing behavior in school for preadolescent children from economically disadvantaged families     

Ackerman BP  Izard CE  Kobak R  Brown ED  Smith C 《Child development》2007,78(2):581-596

This longitudinal study of 105 economically disadvantaged children examined the relation between reading problems and internalizing behavior in 3rd- and 5th-grade assessments (8- to 12-year olds). The variable-centered results showed that reading problems predicted change in internalizing behavior in the context of child and family predictors. The person-centered results showed that children with reading problems in both grades had higher internalizing scores in 5th grade but not in 3rd grade than children with reading problems in 3rd grade or no problems. Child-reported negative emotion experiences varied similarly across grade. The results tie reading problems to emotional distress in school and support conclusions about the direction of effects and the internalization of academic difficulty for disadvantaged children.  相似文献   

Impact of a statewide home visiting program to prevent child abuse   总被引：1，自引：0，他引：1  

Duggan A  Caldera D  Rodriguez K  Burrell L  Rohde C  Crowne SS 《Child abuse & neglect》2007,31(8):801-827

OBJECTIVES: To assess the impact of a voluntary, paraprofessional home visiting program in preventing child maltreatment and reducing the multiple, malleable psychosocial risks for maltreatment for which families had been targeted. METHODS: This collaborative, experimental study focused on 6 Healthy Families Alaska (HFAK) programs; 325 families were enrolled in 2000-2001, randomized to intervention and control groups, and interviewed to measure baseline attributes. Follow-up data were collected when children were 2 years old (85% follow-up rate). Outcomes included maltreatment reports, measures of potential maltreatment and parental risks, for example, poor mental health, substance use, and partner violence. HFAK records were reviewed to measure home visiting services. Home visitors were surveyed to measure perceived effectiveness and training adequacy. RESULTS: Parental risks were common at baseline, and one-sixth of families had a substantiated child protective services report in the child's first 2 years of life. There was no overall program effect on maltreatment reports, and most measures of potential maltreatment. Home visited mothers reported using mild forms of physical discipline less often than control mothers. The groups were similar in their use of more severe forms of physical discipline. There was no program impact on parental risks. There was no impact on outcomes for families with a 'high dose' of home visiting. Home visitors often failed to address parental risks and seldom linked families with community resources. Contradictions in the model compromised effectiveness. CONCLUSIONS: The program did not prevent child maltreatment, nor reduce the parental risks that had made families eligible for service. Research is needed to develop and test strategies to improve the effectiveness of home visiting.  相似文献   

Teaching primary mathematics with challenging tasks: How should lessons be structured?     

James Russo  Sarah Hopkins 《The Journal of educational research》2019,112(1):98-109

Engaging students in a challenging (cognitively demanding) task and launching a mathematics lesson with a task before instruction are two characteristics of a reform-oriented approach to mathematics instruction often considered together. The authors systematically contrasted teaching with challenging tasks using a task-first lesson structure with that of a discussion-first lesson structure to three composite classes of first- and second-grade students (n = 73). Subsequent assessments of mathematical performance revealed that the discussion-first lesson structure was somewhat more efficacious in improving fluency performance but both structures similarly improved problem-solving performance. The findings suggest there is more than one way of incorporating challenging tasks into mathematics lessons to produce sizeable learning gains.  相似文献   

Engaging Urban Ninth Graders in Math: A Complementary Mixed-Methods Study of Teacher Behavior     

Phillips  Sarah F. 《The Urban Review》2019,51(2):201-230

This mixed-methods study examines engaging teaching at one racially and ethnically diverse public school using the self-system process model of student engagement. As theorized, multilevel analyses of student survey data (N?=?580) reveal that student perceptions of structure, autonomy support, and involvement differentiate highly, moderately, and weakly engaging teachers. Classroom observations (N?=?12) and student interviews (N?=?17) suggest that the behavior of autonomy supportive and involved teachers is friendly, helpful, and emphasizes student agency. Although few racial or ethnic differences are observed, autonomy supportive and involved teacher behavior appears particularly critical to the behavioral engagement of Black and Latinx students. Helpfulness may also moderate stereotype threat. Implications for researchers, practitioners, and policy-makers are discussed.

Habitus as foregrounded history: theorising affect in the social formation of embodied practice     

Sarah Leaney 《British Journal of Sociology of Education》2019,40(2):207-221

This article builds upon a tradition of feminist critical engagements with Bourdieu, developing the concept of ‘foregrounded history’ as a way to conceptualise the temporal and affective in processes of habitus formation. Through analysis of affects ‘produced through the social encounter’ within everyday childhoods on a British council estate, the article explores habitus as histories both embodied and felt in the present. Drawing upon ethnographic research conducted within the interrelated fields of the Primary School and the Community Centre, this article considers processes of distinction, disagreement and resistance in the formation of classed positionings on The Estate.  相似文献   

CHE Principles: facilitating authentic and dialogical semi-structured interviews in educational research     

Alice Brown  Patrick A. Danaher 《International Journal of Research & Method in Education》2019,42(1):76-90

This paper examines the values of the CHE principles of Connectivity, Humanness and Empathy as a guiding framework for maximizing the ethical and methodological advantages of semi-structured interview research practices. The authors draw from two separate educational studies and apply the CHE principles to analyse and evaluate the effectiveness of decision-making in facilitating sustainable relationships with the participants in each study. Findings highlight that dialogical relations with participants were evident in both studies, and identify significant junctures where decision-making and actions influenced effective rapport-building and respectful and reciprocal relationships with participants in the research. The CHE principles emerge as providing a robust framework for educational researchers to employ when auditing their decision-making prior to and during their engagement in qualitative interviews.  相似文献   

The evidence for the impact of policy on physical activity outcomes within the school setting: A systematic review     

Catherine B. Woods  Kevin Volf  Liam Kelly  Blthín Casey  Peter Gelius  Sven Messing  Sarah Forberger  Jeroen Lakerveld  Joanna Zukowska  Enrique García Bengoechea  PEN consortium 《运动与健康科学(英文)》2021,10(3):263-276

BackgroundDespite the well-established health benefits of physical activity (PA) for young people (aged 4–19 years), most do not meet PA guidelines. Policies that support PA in schools may be promising, but their impact on PA behavior is poorly understood. The aim of this systematic review was to ascertain the level and type of evidence reported in the international scientific literature for policies within the school setting that contribute directly or indirectly to increasing PA.MethodsThis systematic review is compliant with Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Six databases were searched using key concepts of policy, school, evaluation, and PA. Following title and abstract screening of 2323 studies, 25 progressed to data synthesis. Methodological quality was assessed using standardized tools, and the strength of the evidence of policy impact was described based on pre-determined codes: positive, negative, inconclusive, or untested statistically.ResultsEvidence emerged for 9 policy areas that had a direct or indirect effect on PA within the school setting. These were whole school PA policy, physical education, sport/extracurricular PA, classroom-based PA, active breaks/recess, physical environment, shared use agreements, active school transport, and surveillance. The bulk of the evidence was significantly positive (54%), 27% was inconclusive, 9% was significantly negative, and 11% was untested (due to rounding, some numbers add to 99% or 101%). Frequency of evidence was highest in the primary setting (41%), 34% in the secondary setting, and 24% in primary/secondary combined school settings. By policy area, frequency of evidence was highest for sport/extracurricular PA (35%), 17% for physical education, and 12% for whole school PA policy, with evidence for shared use agreements between schools and local communities rarely reported (2%). Comparing relative strength of evidence, the evidence for shared use agreements, though sparse, was 100% positive, while 60% of the evidence for whole school PA policy, 59% of the evidence for sport/extracurricular PA, 57% of the evidence for physical education, 50% of the evidence for PA in classroom, and 50% of the evidence for active breaks/recess were positive.ConclusionThe current evidence base supports the effectiveness of PA policy actions within the school setting but cautions against a “one-size-fits-all” approach and emphasizes the need to examine policy implementation to maximize translation into practice. Greater clarity regarding terminology, measurement, and methods for evaluation of policy interventions is needed.  相似文献   

The use of paradoxical intention with oppositional behavior in the classroom     

Jacob Edward Brown 《Psychology in the schools》1986,23(1):77-81

Time-out procedures often seem to be overused by teachers and tend to emphasize a linear view of problem behavior. Paradoxical strategies appear to provide a change in the dynamics of the teacher-child relationship and are thus a more systemic way of viewing the behavior. Three case studies are presented where the paradoxical strategies have varying degrees of success. The cases are discussed in terms of the critical aspects of the approach, as demonstrated in the case studies.  相似文献
