Extinction and food-reinforced inhibition of conditioned salivation in dogs     

Dennis L. Herendeen  Martin M. Shapiro 《Learning & behavior》1975,3(2):103-106

The present experiment compared two methods of eliminating a classically conditioned response in dogs, extinction and reinforcement of nonsalivation, using both a within- and between-subjects experimental design. Eighteen dogs were trained for 16 days in Phase I, 16 days in Phase II, and 8 days in Phase III. In Phase I, each subject received classical conditioning training to two stimuli. In Phase II, Group 1 received extinction training to one stimulus and reinforcement of nonsalivation to the other stimulus. Group 2 received continued classical conditioning training to one stimulus and reinforcement on nonsalivation training to the other. Group 3 received continued classical conditioning training to one stimulus and extinction training to the other. In both the within- and between-subjects comparisons, responding to the stimulus associated with extinction was eliminated faster than responding to the stimulus associated with reinforcement of nonsalivation.  相似文献

Disentangling the relationship between working memory and language: The roles of short-term storage and cognitive control     

Pascale Marguerite Josiane Engel de Abreu  Susan Elizabeth Gathercole  Romain Martin 《Learning and individual differences》2011,21(5):569-574

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive abilities. A sample of 119 Luxembourgish 6-year-olds completed several assessments of working memory (complex and simple span), native and foreign vocabulary, syntax, reading, rhyme awareness, and fluid intelligence. Results showed that short-term storage and cognitive control manifested differential links with developing language abilities: Whereas verbal short-term storage was specifically linked to vocabulary; cognitive control manifested unique and robust links with syntax and early reading development. The study suggests that in young children the working memory system is composed of separate but interacting components corresponding to short-term storage and cognitive control that can be distinguished by the roles they play in supporting language acquisition.  相似文献

Improving Writing Skills of Thai EFL Students by Recognition of and Compensation for Factors of L 1 to L2 Negative Transfer     

William J. Sersen 《美中教育评论》2011,(3):339-345

In this study, we examined the likelihood of a TAME （extended technology acceptance model）, in which the interrelationships among computer self-efficacy, perceived usefulness, intention to use and self-reported use of computer-mediated technology were tested. In addition, the gender- and age-invariant of its causal structure were evaluated. The data were collected from a self-reported questionnaire administered to 477 administrative staff of a public university in Malaysia. The results of structural equation modeling supported the adequacy of TAME. Although the TAME＇s causal structure was applicable to both male and female staff, age group appeared to moderate the structural relationships among the constructs of interest.  相似文献   

A Dual Identity Approach for Conceptualizing and Measuring Children's Gender Identity          下载免费PDF全文

Carol Lynn Martin  Naomi C. Z. Andrews  Dawn E. England  Kristina Zosuls  Diane N. Ruble 《Child development》2017,88(1):167-182

The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (M_age = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes.  相似文献

Sustained attention: Stimulus control determined by schedule of cue production interacting with cue duration     

William S. Maki 《Learning & behavior》1975,3(4):312-316

In a study of sustained attention (“vigilance”), pigeons performed a conditional discrimination in a 3-key operant chamber. Pecking a white center key initiated a 0.2- or 2.0-sec cue (a red or green disk). The side keys then displayed white disks, and a peck on the right or left key was reinforced depending on whether the preceding cue was red or green. Pecks on the white center key initiated the cue according to one of two schedules of cue production (FR 1 or VI 7.5 sec). Control of side key choices by 0.2-sec cues was disturbed by transition from FR 1 to VI 7.5, and recovered after the schedule of cue production changed from VI 7.5 back to FR 1. Control of choices by 2.0-sec cues was not affected by changing schedules of cue production. Rates of pecking the cue were higher than rates of cue-producing responses.  相似文献   

Correlation between academic and skills-based tests in computer networks     

William Buchanan 《British journal of educational technology : journal of the Council for Educational Technology》2006,37(1):69-78

Computing‐related programmes and modules have many problems, especially related to large class sizes, large‐scale plagiarism, module franchising, and an increased requirement from students for increased amounts of hands‐on, practical work. This paper presents a practical computer networks module which uses a mixture of online examinations and a practical skills‐based test to assess student performance. For widespread adoption of practical assessments, there must be a level of checking that the practical assessments are set at a level that examinations are set at. This paper shows that it is possible to set practical tests so that there can be a strong correlation between practical skills‐based tests and examination‐type assessments, but only if the practical assessment are set at a challenging level. This tends to go against the proposition that students who are good academically are not so good in a practice test, and vice versa. The paper shows results which bands students in A, B, C, and FAIL groups based on two online, multiple‐choice tests, and then analyses the average time these students took to complete a practical online test. It shows that there is an increasing average time to complete the test for weaker students. Along with this, the paper shows that female students in the practical test outperform male students by a factor of 25%.  相似文献
