Discrimination performance was investigated with pigeons using feature negative (FN) discrimination procedures which differed in the temporal arrangement of the stimuli on S? trials. In both procedures, a single common element was presented on reinforced (S+) trials. In thesimultaneous FN procedure, a distinguishing element was presented simultaneously with the common element of S? trials. In thesequential FN procedure, the distinguishing element preceded onset of the common element on S? trials. In two experiments, the sequential FN procedure yielded better discrimination performance. In Experiment 1, a summation test designed to separate learning and performance variables indicated that sequential FN subjects had learned the negative relationship between the distinguishing element and reinforcement while simultaneous FN subjects had not. In Experiment 2, summation and acquisition tests indicated that the distinguishing element developed inhibitory properties in the sequential FN procedure but not in the simultaneous FN procedure. 相似文献

Audiogenic seizures in mice: Asymmetries of the preconvulsive running pattern and subsequent seizure
Asymmetries in the progression of unilaterally and bilaterally induced audiogenic seizures were examined in DBA/2J and SJL/J mice. Both strains were found to exhibit consistent asymmetries in direction(s) of running as well as in the side of fall during a convulsion. This correspondence suggests that the bursts of running are an integral part of an audiogenic seizure. The incorporation of information on asymmetries of the locomotor prelude in future studies should prove valuable for understanding the physiological mechanisms of audiogenic seizure. 相似文献

Counselor education currently does not have a training model that is systematically employed and contains provisions for individual differences or promotes the development of programs for facilitating transfer of training. In the proposed model, counselor educators must decide which of the counseling student's thinking, feeling, and acting behaviors will become the focus of training efforts. The staff creatively implements its conceptualized behavioral curriculum goals through the application of learning principles to specified counseling student behaviors that are assessed to determine if whether or not the desired behavior changes are occurring. 相似文献

A common trend in higher education is the “flipped” classroom, which facilitates active learning during class. The flipped approach to teaching was instituted in a haematology ‘major’ class and the students’ attitudes and preferences for the teaching materials were surveyed. The curriculum design was explicit and involved four major components (1) the preparation of the students; (2) the weekly pre-class work; (3) the in-class active learning strategies and (4) closing the learning loop using formative quizzes. Each of these components is discussed in detail and was informed by sound pedagogical strategies. Several different sources of information and several freely available software tools to engage the students are discussed. Two iterations are reported here, with improved pass rate for the final examination from 47 to 48 % in the traditional class to 56–65 % in the flipped classroom approach. The majority of students (93 and 89 %) came to the class prepared, after viewing the screencasts and engaged fully with the activities within the face-to-face time. The students perceived that solving case studies (93 %) was the most beneficial activity for their learning and this was closely followed by the production of essay plans (71 %). The majority of students recommended that this approach be repeated the following year (69 and 75 %). 相似文献

ABSTRACTHigher education in the U.S. sees global learning as critical to student development. Over the last seventy years, study abroad has emerged as the method of choice for teaching global knowledge and intercultural competence. In this context, community-based global learning programs are a type of program where students live in communities to learn directly from people and place. Looking at a field studies program in Northern Thailand, this paper explores the educational mobility of study abroad and impact on host communities. It shares findings on the experiences of two communities who have hosted study abroad students for almost twenty years. Best practices and recommendations for faculty and institutions running community-based global learning programs are shared, including the centrality of community voice in curriculum, benefits of applying a range of pedagogical methods on course, the critical nature of adequately preparing students for cultural immersion, and compensating communities justly for their work. 相似文献

Do infants use past linguistic information to interpret an ambiguous request for an object? When infants in this research were shown 2 objects, and asked for 1 with an indefinite request (e.g., "Can you get it for me?"), both 15- and 18-month-olds used the speaker's previous reference to an absent object to interpret the request. The 18-month-olds did so even when the request was made after a 2.5-min delay. When the request was made by a person who did not participate in the conversation, the infants did not use the previous verbal information. These results demonstrate infants' ability to use language as a source of information in ambiguous contexts and indicate an early appreciation of the shared nature of conversation. 相似文献

The current study examines the effects of digital scaffolding on the English literacy of fourth- and sixth-grade students. A total of 1085 native English-speaking and language minority students from 25 treatment classes and 20 control classes across three school districts participated in this study for one school year. Treatment students read their English language arts and social studies text in visual-syntactic text format (VSTF) on their laptops and control students read the regular block format of the textbook either on their laptops or in print. Observations and interviews revealed that VSTF reading facilitated instruction processes and student learning in reading activities. The results of California Standard Tests (CST) before and after the treatment revealed that sixth-graders who received syntactic scaffolding outperformed control students on the composite CST score. In particular, reading in VSTF benefited the treatment students in three CST sub-categories: word analysis, written conventions and writing strategies. This study suggests that future research should investigate instructional strategies that support reading and writing development of adolescents, including at-risk students, using syntactic scaffolding. 相似文献

Objectives: envy is a negative social emotion that stems from a social comparison. This study explores the effect of deservingness on the intensity of schadenfreude (pleasure in another’s misfortune) in situations of invidious comparison. Method: the participants, 181 children between the ages of three and 10, were asked to describe what an envious character felt when the character (s/he) envied had lost an (deserved or undeserved) advantage. They were also asked to explain their answers. Results: the findings showed that schadenfreude was more intense when the lost advantage was undeserved than deserved only in young children. The difference between conditions decreased with age. The children’s explanations of schadenfreude were based on the damage to the envied person, whereas the responses of pity were justified by the misfortune and equitable ending (no one wins) of the story. Conclusions: the discussion addresses some of the possible factors, such as the acquisition of display rules, deservingness and perception of equality, that contribute to children’s understanding of emotions such as envy and schadenfreude. 相似文献
