Three pigeons were trained in a three-item simultaneous same/different task. Three of six stimulus combinations were not trained (untrained set) and were tested later. Following acquisition, the
subjects were tested with novel stimuli, the untrained set, training-stimulus inversions, and object shape and color manipulations.
There was no novel-stimulus transfer—that is, no abstract-concept learning. Two pigeons showed partial transfer to untrained
pairs and good transfer to stimulus inversions, suggesting that they had learned the relationship between the stimuli. Lack
of transfer by the third pigeon suggests item-specific learning. The somewhat surprising finding of relational learning by
2 pigeons with only six training pairs suggests restricted-domain relational learning that was controlled more by color than
by shape features. Individual differences of item-specific learning by 1 pigeon and relational learning by 2 others demonstrate
that this task can be learned in different ways and that relational learning can occur in the absence of novel-stimulus transfer. 相似文献

Understanding academic vocabulary is essential to student success in school. Use of academic vocabulary words in writing is considered one of the strongest measures of how well a reader understands a given word. In theory, willingness to use academic vocabulary in writing indicates the complexity of acquiring representations of the word’s orthography, phonology, and semantics based on the word’s characteristics. In addition, a learner’s overall literacy skills should relate to whether they attempt to use words. In the present study, sixth graders (n = 66), seventh graders (n = 60), and eighth graders (n = 41) learned 25 academic vocabulary words in a supplementary academic vocabulary intervention and were then asked to use those words in short persuasive essay drafts. We measured whether these students attempted to use a word (a binary uses outcome) and the number of times a student used a word (a continuous attempts outcome) and used cross-classified random effects models to examine how (a) the orthographic, phonological, and semantic characteristics of words and (b) the students’ literacy-related characteristics related to their uses and attempts. For word characteristics, students were more likely to use and attempt high frequency than low frequency words. For student characteristics, students proficient on the state exam were more likely to use and attempt the words, and students learning English were less likely to attempt the words. Implications for vocabulary intervention and writing instruction are discussed. 相似文献

The purpose of this paper is to compare the approach to promoting positive relationships between Catholics and Protestants in two types of integrated primary school in Northern Ireland. Drawing on qualitative interviews with teachers, governors and parents in one transforming school and one grant maintained integrated school, i.e. one representative of each of the two types, the paper shows that whilst there are distinctions in the ways that the schools promote their image and ethos, the ‘lived reality’ of the schools, as reported by the research participants, is almost indistinguishable. The paper suggests that both schools tend not to refer to or explore cultural difference and that this tendency to ‘minimise difference’ seems to have the potential to silence school members who do wish to explore their own and other cultures. It is argued that such practices are likely to impede rather than facilitate the progress of good inter‐community relations. 相似文献

Research Findings: Bug-in-ear coaching implemented under highly controlled situations has a promising research base. Yet few researchers have examined its effects when implemented within less controlled environments using authentic professional development conditions. The purpose of this study was to examine the implementation and effects of bug-in-ear coaching when staff from a community organization served as community coaches for early childhood educators. We found that community coaches implemented bug-in-ear methods, but additional supports may be necessary to increase the intensity and quality of feedback provided. Effects of the intervention were observed for 1 of the 6 targeted outcomes for educators. However, effects did not translate to children’s communication outcomes. Practice or Policy: Bug-in-ear coaching is 1 method of providing early childhood educators with performance-based feedback. One benefit is that while community coaches observe educators live, they provide feedback that educators can immediately use to improve practice. However, bug-in-ear coaching poses challenges with respect to reviewing goals and reflecting on one’s performance. Community coaches and educators should systematically plan for reflection so that educators can create new implementation goals to improve their practice. Changing educator practice is a complex endeavor, but bug-in-ear coaching is a promising tool for doing so in a supportive manner. 相似文献

Globalization has led to an increase in United States-influenced counseling programs the world over; however, the extent to which these training models apply to other cultures is unclear. Using a sample of master’s-level counseling students studying in the Czech Republic (n?=?5), the authors conducted a phenomenological inquiry examining the experiences of European students trained in a program developed and supervised by faculty in the United States. Three themes (and potential barriers) related to English-language training programs in Central Europe included: cultural differences between faculty and students, complications related to the notion of professional identity, and concerns related to the utility of wellness-based principles in the Czech Republic. Implications for educators include cultural adaptation of training and course material as well as reframing illness perspectives through a wellness lens. 相似文献

This article examined the impact of mobile technology on young pedestrians, bicyclists, and drivers. A systematic search yielded 41 articles meeting inclusion criteria: peer‐reviewed, published before February 1, 2016, behavioral outcome related to pedestrian, bicycling, or driving in the presence of mobile technology use, youth sample. Eleven studies were meta‐analyzed to evaluate increased risk for crash/near‐crash while distracted. Risk of bias and quality of research were assessed. Across methodologies, developmental stages, and type of distracting task, mobile technology use impairs youth safety on the road. Quality of evidence was low (pedestrian) to moderate (driving). Findings are discussed from the perspective of cognitive and visual distractions. Policy and behavioral efforts should continue to reduce mobile technology use in transportation settings. 相似文献

Rats will approach and contact a lever whose insertion into the chamber signals response-independent food delivery. This “autoshaping” or “sign-tracking” phenomenon has recently attracted considerable attention as a platform for studying individual differences in impulsivity, drug sensitization, and other traits associated with vulnerability to drug addiction. Here, we examined two basic stimulus selection phenomena—blocking and overshadowing—in the autoshaped lever pressing of rats. Blocking and overshadowing were decidedly asymmetrical. Previously reinforced lever-extension conditioned stimuli (CSs) completely blocked conditioning to auditory cues (Exps. 1 and 2), and previously nonreinforced lever-extension CSs overshadowed conditioning to auditory cues. By contrast, conditioning to lever-extension CSs was not blocked by either auditory (Exp. 3) or lever-insertion (Exp. 4) cues, and was not overshadowed by auditory cues. Conditioning to a lever-insertion cue was somewhat overshadowed by the presence of another lever, especially in terms of food cup behavior displayed after lever withdrawal. We discuss several frameworks in which the apparent immunity of autoshaped lever pressing to blocking might be understood. Given evidence that different brain systems are engaged when different kinds of cues are paired with food delivery, it is worth considering the possibility that interactions among them in learning and performance may follow different rules. In particular, it is intriguing to speculate that the roles of simple cue–reinforcer contiguity, as well as of individual and aggregate reinforcer prediction errors, may differ across stimulus classes. 相似文献

Genetic and Environmental Links Between Natural Language Use and Cognitive Ability in Toddlers 下载免费PDF全文
Although the phenotypic correlation between language and nonverbal cognitive ability is well‐documented, studies examining the etiology of the covariance between these abilities are scant, particularly in very young children. The goal of this study was to address this gap in the literature by examining the genetic and environmental links between language use, assessed through conversational language samples, and nonverbal cognition in a sample of 3‐year‐old twins (N = 281 pairs). Significant genetic and nonshared environmental influences were found for nonverbal cognitive ability and language measures, including mean length of utterance and number of different words, as well as significant genetic covariance between cognitive ability and both language measures. 相似文献

In this study, researchers used a customized 360‐degree method to examine the frequency with which 1,546 men and 721 women leaders perceived themselves and were perceived by colleagues as using 10 relational and 10 task‐oriented leadership behaviors, as addressed in the Management‐Leadership Practices Inventory (MLPI). As hypothesized, men and women leaders, as well as their supervisors, employees, and peers, perceived women leaders to employ nine of the 10 relational leadership behaviors significantly more frequently than men leaders. Additionally, the employees' perceptions of their women leaders' use of task‐oriented behaviors were significantly higher when compared to similar assessments from the employees of men leaders. However, the leaders as well as their supervisors and peers perceived men and women leaders' use of task‐oriented behaviors as approximately equal. Broader implications of these findings are discussed. 相似文献
