Fifteen-day-old rats made random choices in a T-maze, while adult levels of alternation (approximately 70%) were noted among 30-day-olds. Also, younger pups were insensitive to a lengthening of the intertrial interval, unlike older animals whose rate of alternation decreased when a 1-h delay was interposed between arm entries. These findings are consistent with the hypothesis that hippocampal development is a factor in the ontogeny of postweaning locomotion. The unsystematic pattern of goal-arm selections among 15-day-olds suggests that ontongenetic variation in the utilization of stimuli may underlie developmental shifts in spontaneous alternation. 相似文献

Children raised in neighborhoods with low socioeconomic status (SES) are at risk for low academic achievement. Identifying factors that help children from disadvantaged neighborhoods thrive is critical for reducing inequalities. We investigated whether children’s prosocial behavior buffers concurrent and subsequent academic risk in disadvantaged neighborhoods in Bradford, UK. Diverse children (N = 1,175) were followed until age seven, with measurements taken at four times. We used governmental indices of neighborhood-level SES, teacher observations of prosocial behaviors, and direct assessments of academic achievement. Neighborhood SES was positively associated with academic achievement among children with low levels of prosocial behavior, but not among children with high levels of prosocial behavior. Prosocial behavior may mitigate academic risk across early childhood. 相似文献

Millions of college students in the U.S. are enrolled in online courses, with the global pandemic resulting in a “pivot to online” for educational and health reasons. African-American college students continue to face barriers to academic success, and this response to Kuo and Belland (in Educ Technol Res Dev 64(4):661–680, 2016) investigates how the concept of “learner interaction” supports success. Finally, this response includes examples from online courses informed by “critical humanizing pedagogy,” in which social interaction is a key driver of learning.

Interactive computerized modules have been linked to improved retention of material in clinical medicine. This study examined the effects of a new series of interactive learning modules for preclinical medical education, specifically in the areas of quiz performance, perceived difficulty of concepts, study time, and perceived stress level. We randomly allocated 102 medical student volunteers into control and experimental groups. All participants studied selected anatomical and physiologic concepts using existing material (lecture notes, textbooks, etc.), while those in the experimental groups used the new interactive modules as well. All participants completed a quiz to test their knowledge of the assigned concepts and a survey to assess their subjective experiences in studying with the modules. We found a trend toward higher quiz scores in the experimental group relative to the control group, though it did not reach statistical significance (P = 0.31). Perceived concept difficulty was significantly reduced among those who studied with the modules (P < 0.001), and the number of hours spent studying the concepts was significantly increased (P = 0.028). Of those who used the modules, 83% rated them as “very helpful” or “extremely helpful.” No significant differences existed between participants' reported stress levels during the course of the study (P = 0.44). Our data suggest that medical students may learn more effectively and feel less intimidated by difficult concepts when interactive modules supplement traditional instruction.

The current study explored the values preservice teachers use as motivation for pursuing a teaching career. Preservice teachers (N = 97) from a large Northeastern urban university were chosen to complete a survey measuring personal utility value, social utility value, and epistemic value. Data analysis was conducted using exploratory factor analysis, correlations, multivariate analysis of variance (MANOVA), and multivariate analysis of covariance (MANCOVA). Results indicated moderate and significant correlations among subscales; a two-group MANOVA demonstrated that females were rated higher on the subscale desire to work with children/adolescents and Secondary Education participants rated highest on social contribution; and a MANCOVA using sex as the covariate demonstrated that participants pursuing Early Childhood Education were rated higher on the personal utility value main scale and the time for family and job transferability subscales. 相似文献

This study investigated inclusion of epistemic value into Richardson and Watt Factors Influencing Teaching Choice (FIT-Choice) framework to produce a more robust, useful teacher motivation model. We specifically examined pre-service teachers’ social utility value (SUV), personal utility value (PUV) and epistemic value regarding pursuing future professional engagement and development. Using principal axis factoring, we found four main factors: PUV, SUV, epistemic value—future value of knowledge (EVF) and persistence/satisfaction. These factors were then used in a structural equation model (SEM) to predict pre-service teachers’ intentions to pursue future professional engagement. Results provided the following three insights: (a) SUV was the most consistent, positive predictor of professional engagement and predicted all dependent variables; (b) EVF was a newly identified factor and a positive predictor of pre-service teachers’ desire to pursue a leadership position and (c) PUV negatively predicted planned effort and a desire to pursue a leadership position. 相似文献

Military service is acknowledged as one of many elements voters use to evaluate candidates, but it has primarily been studied as a univariate element of a candidate’s biography. This project experimentally manipulates veteran status, gender, and partisanship as potentially interactive heuristics for evaluation of a hypothetical candidate specifically regarding military issues. We found an almost universal benefit enjoyed by veterans over civilians regardless of whether the candidate was a member of the participant’s partisan ingroup or outgroup. We also found little evidence of a gender penalty, and even a benefit for women candidates who were veterans, though this benefit was restricted to evaluations from Republican women. We also found that Democratic respondents assigned a penalty to outgroup veteran men candidates. We explain these nuanced findings in the context of moderation by gender mis/alignment between participant and candidate. Implications of the study are offered. 相似文献

College age bodybuilders were compared by sex (female, male) and steroid intake (nonuse, use) on two variables: body image dissatisfaction and body image distortion. Results of 2 × 2 ANOVAs (sex by steroid use) revealed only a significant effect for gender on body distortion. No steroid‐use differences were apparent for either body image dissatisfaction or body image distortion. Further analyses indicated that female bodybuilders were equally split between desiring more muscle bulk versus a thinner frame, whereas the majority of male bodybuilders wanted to build more muscle mass. These results are compared to previous research with non‐bodybuilders wherein body image dissatisfaction was unidirectional for females (i.e., all desired slimness) yet bidirectional for males (i.e., some aspired to increased muscle mass whereas others sought a reduction in body fat). © 2001 John Wiley & Sons, Inc. 相似文献

The study reported here investigated experienced teachers’ views on several nature of science (NOS) issues 2 to 5 years after they completed a demanding secondary science teacher education program in which the NOS was an extensive and recurring component. Both quantitative and qualitative data were collected and analyzed to determine study participants’ NOS understanding. Study participant’s NOS views were determined to be generally accurate and robust, suggesting that experiences in their science teacher education program had a long-lasting positive impact on NOS understanding. The preservice program that study participants completed has several unique features that may account for that long-lasting impact and has implications for preservice and inservice science teacher education professional development. 相似文献
