Injected flavor as a CS in the conditioned aversion preparation     

W. P. Bellingham  D. Lloyd 《Learning & behavior》1987,15(1):62-68

Three experiments were conducted to determine the effectiveness of intravenous (IV) flavor injections in the formation of conditioned taste aversions and in the attenuation of neophobia. In Experiment 1, two groups of rats were permitted to drink either a .1% saccharin solution or tap water followed immediately by IV injections of lithium chloride (LiCl), and two more groups were given IV injections of a 2% saccharin solution followed immediately by IV injections of either LiCl or distilled water. Injected flavor did not serve as an effective CS for the conditioning of an aversion to .1% saccharin. The second experiment employed a two-bottle procedure to detect attenuation of neophobia using the injected-flavor technique. It was found that, whether saccharin had been injected intravenously (2%), injected intraperitoneally (2% IP), or orally consumed (.1%), neophobia for .5% saccharin was attenuated equally relative to controls. CS-US intervals were manipulated in the final experiment such that IP injections of 2% saccharin solution were followed 0–480 min later by IP injections of LiCl. In this case, it was shown that injected flavor (2% saccharin) could act as an effective CS if the US was delayed (optimally about 120 min) and when the test solution was .1% saccharin. The delay gradient found in Experiment 3 was interpreted as a generalization gradient where optimum conditioning was displayed at the point where the concentration of saccharin circulating in the animal at the time of illness onset most closely matched the concentration of the test solution.  相似文献   

Sequential Associations Between Caregiver Talk and Child Play in Autism Spectrum Disorder and Typical Development          下载免费PDF全文

This study examined sequential associations between child play and caregiver talk in 98 caregiver–child dyads (M_{mental age} = 14 months). Fifty dyads included a child with autism spectrum disorder (ASD). Analyses revealed sequential associations between child play and caregiver follow‐in (FI) utterances (utterances related to the child's attentional focus) were stronger in the ASD as compared to the typically developing (TD) group. FI utterances were more likely to elicit functional play than caregiver‐focused utterances, and more so in the ASD group. Across groups, FI directives were more likely to elicit functional play than FI comments. These findings have important implications for research involving caregiver–child play as an early intervention context for children with ASD.  相似文献

The Parent-Caregiver Relationship Scale: Rounding Out the Relationship System in Infant Child Care     

James Elicker  Illene C. Noppe  Lloyd D. Noppe  Cheryl Fortner-Wood 《Early education and development》1997,8(1):83-100

The Parent-Caregiver Relationship Scale (PCRS) was developed and field tested as a measure of the perceived quality of the relationship between the parent and the child care provider (“caregiver”) of an infant or toddler. PCRS items were based on review of the parent-caregiver relations literature and interviews with parents and caregivers. The parent and caregiver forms of the scale were administered to 217 parents and caregivers in child care centers and family child care homes. Analysis of the scale and its psychometric properties resulted in potentially useful subscales with adequate reliability. The PCRS showed predicted correlations with other child care context variables, providing preliminary support for its validity. The PCRS shows promise as a relationship-level measure for studies of infants, parents, and caregivers in the context of full-time child care.  相似文献

Impacts of enquiry-based science teaching on achievement gap between high-and-low SES students: findings from PISA 2015     

Nai-En Tang  Lloyd Barrow  William Romine 《International Journal of Science Education》2019,41(4):448-470

The purpose of this study was to empirically investigate, in a large-scale assessment, the prevalence of enquiry-based teaching, as defined by PISA, implemented in science lessons, and the extent to which it is related to students from different socioeconomic status (SES) family backgrounds in the U.S. The Programme of International Student Assessment (PISA) 2015 data including 5,146 students in the U.S. were used. A Latent Profile Analysis (LPA) was conducted to classify students into different science teaching subgroups. Mixture regression analysis was conducted to examine whether there the association between SES and achievement varied across science teaching subgroups. Four science teaching subgroups were identified, varying in the frequency of and type of teaching practices used. Students’ attitudes, gender, science instruction time, and reading achievement are significant predictors of the subgroup membership. SES-achievement gap also varied across the science teaching subgroups. Discussions for the results and suggestions for future study were presented.  相似文献   

Derivation of an Age and Weight Handicap for the 5K Run     

Paul M. Vanderburgh  Lloyd L. Laubach 《Measurement in physical education and exercise science》2013,17(1):49-59

The adverse effect of increasing age and/or body weight on distance run performance has been well documented. Accordingly, nearly all five kilometer (5K) road races employ age categories and, sometimes, a heavier body weight classification. Problems with such conventions include small numbers of runners within older age categories and the advantage given to the lightest runners within each weight category. We developed a 5K Handicap (5KH), a model that calculates an adjusted run time based on the inputs of actual 5K run time, age, and body weight for men and women. This adjusted time, then, can be compared between runners of different ages and body weights. The purpose of this paper was to explain, in detail, the derivation of the 5KH formula using published theoretical and empirical findings on age, body weight and distance run time relationships. To our knowledge, the 5KH is the first such model and overcomes the problems associated with being heavier within one weight class and having too few runners in certain age categories. We are currently undertaking large-scale validation studies and evaluation of its race day implementation.  相似文献

Entryway into the child protection system: The impacts of child maltreatment reporting policies and reporting system structures     

Julie A. Steen  Lloyd Duran 《Child abuse & neglect》2014

This study was designed to assess the impacts of maltreatment reporting policies and reporting system structures on four aspects of entry into the child protection system (the maltreatment referral rate, the percentage of referrals screened in for investigation, the screened-in report rate and the substantiated report rate). Using secondary data from several sources, eight multiple linear regression models were created and analyzed. Results from a sample of 44 states indicated significant effects for system structure but no effects for reporting policies. Specifically, states with decentralized reporting system structures were significantly more restrictive in access than other states. These results have implications for child welfare administrators and policymakers seeking to maximize access for maltreated children and their families.  相似文献
