The functional equivalence of operant behavior and foraging     

Jesse Dallery  William M. Baum 《Learning & behavior》1991,19(2):146-152

Many researchers have used the controlled procedures of operant methodology to test the predictions of foraging theory on the assumption that foraging is operant behavior and operant behavior is foraging. This experiment tested the assumption that leverpressing is functionally equivalent to search effort. Four rats were exposed to two situations: a naturalistic foraging situation (a “patch”) and a standard operant chamber. Each condition represented a different prey density on the patch and a corresponding change in the probability of reinforcement in the chamber. The average number of presses per pellet was linearly related to the density of pellets on the patch. This result indicates that leverpresses were functionally equivalent to search effort.  相似文献

The Efficacy of Preschool Developmental Indicators as a Screen for Early Primary School-Based Literacy Interventions     

Philip J. Schluter  Richard Audas  Jesse Kokaua  Brigid McNeill  Barry Taylor  Barry Milne  Gail Gillon 《Child development》2020,91(1):e59-e76

Literacy success lays the foundation for children's later educational, health, and well-being outcomes. Thus, early identification of literacy need is vital. Using data from New Zealand's national preschool health screening program for fiscal years 2010/2011–2014/2015, demographic and health variables from 255,090 children aged 4 years were related to whether they received a literacy intervention in early primary school. Overall, 20,652 (8.1%) children received an intervention. Time-to-event analysis revealed that all considered variables were significantly related to literacy intervention (all p < .01), but the full model lacked reasonable predictive power for population screening purposes (Harrell's c-statistic = .624; 95% CI [.618, .629]). Including more direct literacy measures in the national screening program is likely needed for improvement.  相似文献   

Temperamental Emotionality Attributes as Antecedents of Children's Social Information Processing     

Patrick T. Davies  Jesse L. Coe  Rochelle F. Hentges  Melissa L. Sturge-Apple  Michael T. Ripple 《Child development》2020,91(2):508-526

This study examined temperament dimensions of emotion as precursors of children's social information processing (SIP) of stressful peer events. Two hundred and forty-three preschool children (M = 4.60 years) and their primary caregivers participated in two measurement occasions spaced 2 years apart. Observations of temperamental anger, fearful distress, positive affect, and effortful control were assessed in multiple laboratory tasks across two visits at Wave 1. SIP assessments from vignettes of peer challenges were repeated across two waves and included: eye tracking measures of attention to peer emotion displays, hostile attribution bias, hostile solutions, and subjective distress. Findings from structural equation models with inclusion of autoregressive controls indicated that effortful control, fear, and anger predicted subsequent changes in specific SIP dimensions.  相似文献   

Variations in article seeking and reading patterns of academics: What makes a difference?     

Carol Tenopir  Donald W. King  Jesse Spencer  Lei Wu 《Library & information science research》2009

Although scholarly articles play an important role in the work life of academics, specific patterns of seeking and reading scholarly articles vary. Subject discipline of the reader influences many patterns, including amount of reading, format of reading, and average time spent per reading. Faculty members in different disciplines exhibit quite distinct patterns of reading. Medical/health faculty read more than others and mainly for current awareness purposes, while engineering faculty spend more time on average per article reading, and they also read more for research. Other factors that influence some reading patterns include work responsibilities (weighted towards more teaching or more research), age (young faculty are more likely to read on-screen from the open Web) and productivity of the reader, and purpose of the reading (readings for research and writing are more likely to be from a library collection). The ability to predict scholarly article seeking and reading patterns will assist journal editors, publishers, and librarians design better, more targeted journal systems and services.  相似文献   

The interrupted learner: How distractions during live and video lectures influence learning outcomes          下载免费PDF全文

Andrew H. Zureick  Jesse Burk‐Rafel  Joel A. Purkiss  Michael Hortsch 《Anatomical sciences education》2018,11(4):366-376

New instructional technologies have been increasingly incorporated into the medical school learning environment, including lecture video recordings as a substitute for live lecture attendance. The literature presents varying conclusions regarding how this alternative experience impacts students' academic success. Previously, a multi‐year study of the first‐year medical histology component at the University of Michigan found that live lecture attendance was positively correlated with learning success, while lecture video use was negatively correlated. Here, three cohorts of first‐year medical students (N = 439 respondents, 86.6% response rate) were surveyed in greater detail regarding lecture attendance and video usage, focusing on study behaviors that may influence histology learning outcomes. Students who reported always attending lectures or viewing lecture videos had higher average histology scores than students who employed an inconsistent strategy (i.e., mixing live attendance and video lectures). Several behaviors were negatively associated with histology performance. Students who engaged in “non‐lecture activities” (e.g., social media use), students who reported being interrupted while watching the lecture video, or feeling sleepy/losing focus had lower scores than their counterparts not engaging in these behaviors. This study suggests that interruptions and distractions during medical learning activities—whether live or recorded—can have an important impact on learning outcomes.

Students’ Perceptions of Mental Health Counseling in the United Arab Emirates (UAE)     

Jesse?A.?BrinsonEmail author  Fatima?Salem?Saeed?Al-amri 《International journal for the advancement of counseling》2005,27(4):495-512

Counseling services in the United Arab Emirates (UAE) have focused on counseling in the elementary and secondary schools. To date, the idea of the private practitioner of mental health counseling has been virtually nonexistent. However, education officials at the University of the United Arab Emirates (UAE) have been exploring the option of following the international trends of preparing students for mental health counseling services, with special emphasis in marriage and family. A counselor education degree would allow individuals to operate private practices to address various concerns that impact individuals within the society at large. No instruments that measure perceptions of counseling from an international perspective were found for the purposes of this study. Therefore, it was necessary for the authors to devise and test a new tool. Surveys were completed by a sample of 141 undergraduate students regarding their perceptions of the importance of counseling in UAE society and the role of the counselor in society and other general questions regarding perceptions of counseling. With this initial effort, psychometric properties of the ‘Perceptions about Counseling Survey’ appeared promising. Results revealed that students had a favorable view toward the role of the counselor in UAE society. Results further revealed that students perceived the counseling profession as favorable. Given that the participants were predominately female, the results were analyzed from the social and cultural perspective of women in Arab society and the social psychological theory of ‘attitude’ is considered as a contextual backdrop.  相似文献   

Family Instability and Young Children's School Adjustment: Callousness and Negative Internal Representations as Mediators          下载免费PDF全文

Jesse L. Coe  Patrick T. Davies  Melissa L. Sturge‐Apple 《Child development》2018,89(4):1193-1208

This study examined the mediating roles of children's callousness and negative internal representations of family relationships in associations between family instability and children's adjustment to school in early childhood. Participants in this multimethod (i.e., survey, observations), multiinformant (i.e., parent, teacher, observer), longitudinal study included 243 preschool children (M_age = 4.60 years) and their families. Findings from the lagged, autoregressive tests of the mediational paths indicated that both children's callousness and negative internal representations of family relationships mediated longitudinal associations between family instability and children's school adjustment problems over a 2‐year period (i.e., the transition from preschool to first grade). Findings are discussed in relation to the attenuation hypothesis (E. J. Susman, 2006) and emotional security theory (EST; P. T. Davies, M. A. Winter, & D. Cicchetti, 2006).  相似文献   

Testing a motivational model of achievement: How students’ mathematical beliefs and interests are related to their achievement     

Brett D. Jones  Jesse L. M. Wilkins  Margaret H. Long  Feihong Wang 《European Journal of Psychology of Education - EJPE》2012,27(1):1-20

Blackwell et al. (Child Development 78(1):246–263, 2007) tested a motivational model of achievement in which an incremental theory of intelligence leads to learning goals and positive effort beliefs, which leads to fewer ability-based, helpless attributions, and more positive strategies, which leads to improved grades. In the present study, we tested this model by using a different population, using domain-specific items, comparing the results across gender, including “interest” as another variable in the model, and assessing the impact of achievement as an antecedent and outcome variable in the model. Participants included 163, mostly White, ninth-grade Algebra students from a suburban school in southwest Virginia, USA. We established that the model had a relatively good fit to the data and all paths were statistically significant when achievement was used as both an antecedent and outcome variable. The standardized path coefficients were consistent with those reported by Blackwell et al. and the model was invariant across genders. Furthermore, we documented that interest could be included as another mediating variable in the model. The results of this study provide evidence to support the validity of the relationships between the constructs in the Blackwell et al. model for the population examined.  相似文献
