In two experiments, saccharin (CS) and lithium chloride (US) were paired in a context consisting of specific visual, auditory, tactual, and olfactory cues. The saccharin aversion was then extinguished in a context free from conditioning-context cues. Later, saccharin preference tests were given in the presence and absence of these cues. The results indicated that the background cues of the conditioning trial controlled the amount of saccharin drunk on extinction trials, and, furthermore, that extinction of the taste aversion was context specific; i.e., groups given extinction trials in a different (from conditioning) context retained their saccharin aversion in the conditioning context only. The results indicate an important role played by the exteroceptive context in taste-aversion conditioning.  相似文献

The cognitive abilities of a group of dysphasic children in a special school in Finland were examined in this study to answer the following questions: Can we categorize their cognitive processing as planning, arousal-attention, simultaneous and successive processing (PASS)? The second question was concerned with detecting subgroups within the dysphasic sample in terms of PASS processes. The subjects were 60 dysphasic children in a special school. Their ages ranged from 7 to 19 years. All subjects were administered tests of planning, arousal-attention as well as simultaneous and successive processing. They were also administered the Wechsler test of intelligence for children and adults according to their ages, two sub-scales of Wechsler memory scale, as well as three ad hoc tests, cancellation task, KS persons and Rey Osterrieth copy task. The results of the factor analysis generally confirmed the emergence of the four PASS factors. As a results of cluster analysis, two subtypes of dysphasics emerged categorized as clearly high and low in the successive factor as well as relatively high and low on the simultaneous factor scores. The low-simultaneous/low-successive group was significantly lower in WISC verbal IQ the Wechsler memory scale for logical memory, and the ad hoc test of KS persons. The results were discussed, in terms of the importance of understanding the language problems typically associated with the two subtypes as well as the remedial program which will take into account their cognitive differences in spite of the fact that both groups had significant language impairment.  相似文献

The aim of the present study was to investigate teachers’ sickness presenteeism (SP). We examined the prevalence of SP in a sample of teachers as well as work-related and health-related influencing factors of teachers’ SP. We used a cross-sectional study design. Teachers working at different types of schools in Rhineland-Palatinate (Germany) participated in an online survey. We used Pearson’s Chi-squared test (in case of categorical variables) or Mann–Whitney-U-test (in case of continuous variables) to test for differences between SP and sociodemographic/work-related/health-related factors. Factors influencing SP were identified using multivariable logistic regression analyses. Nine hundred and twenty-four teachers working at 42 different schools completed the questionnaire (response proportion: 50.1%). The prevalence of SP in our study was 57.1%. The multivariable logistic regression analyses showed less support by supervisors (aOR: 1.77; 95-CI: 1.21–2.60), inappropriate administration efforts (aOR: 1.56; 95-CI: 1.16–2.11), and inappropriate recognition of performance (aOR: 1.44; 95-CI: 1.04–198) as well as exhaustion/fatigue (aOR: 2.29; 95-CI: 1.71–3.08) as main predictors of teachers’ SP. SP is widespread among teachers. As SP is associated with impairment of psychological and physical health in the long run, it is important to implement measures to reduce SP. A climate of support and cooperation as well as assistance for ill teachers to deal with work missed due to absence might be useful strategies.  相似文献

The link between formal education and the formation of national attachment is widely acknowledged. Yet, research on teachers’ national attachment is still relatively rare. Based on a comparative analysis of survey data obtained from 281 Berlin and London state secondary school head teachers, this paper proposes a multivariate model in which notions of national identity, levels of national pride and levels of supranational attachment represent predictors of national attachment. The respective statistical analyses reveal striking cross‐national similarities in terms of the individual and joint explanatory impact of these predictors. Other findings concern correlations between different notions of Britishness/Germanness and levels of national attachment, the relationship between national and supranational attachment, and associations between national pride and national attachment.  相似文献

This article is based on results from a research project which focused on chemistry teachers and student narratives from lived experience. The purpose was to find a way to make abstract chemistry more meaningful. The project began with six experienced teachers who used narratives and stories as a didactic tool. These narratives stemmed from the teachers individual lived experience and thus were designed differently. Later, interviews with students showed that five adult students and six younger students all appreciated the use of narratives as ameaning-making activity to help them grasp the abstract subject. The most interesting finding was that the students revealed several narratives from their own lives where the theories of chemistry played an important role in explaining events that otherwise had been mysterious to them. Thus the teachers and students showed that the ancient human method of sharing experience through narrative is still alive and useful in chemistry education.  相似文献

ABSTRACT

This case study examined how the agency of a fifth-grade pupil appeared across different learning environments in the primary school context. In this study, agency is defined as the initiatives taken by an individual in interactive situations. The research question is: how does a pupil’s agency manifest and vary through taking initiatives across different learning environments within curriculum-based education? The empirical data consist of 50 video episodes including learning activities in a classroom, in a vegetable garden and on a nearby farm. The findings show that the pupil’s agency varied across learning environments, manifesting itself through complementing, supportive, constructive and challenging initiatives. When developing pedagogy that supports learning across formal and informal learning environments, it is essential to enable pupils to take different kinds of initiatives and to exercise their agency in versatile contexts.  相似文献

To investigate the role of early regulatory problems (RP), such as problems in feeding, sleeping, and calming down during later development, the association between parent-reported RP at 3 months (no-RP, n = 110; RP, n = 66) and attention to emotional faces at 8 months was studied. Eight-month-old infants had a strong tendency to look at faces and to specifically fearful faces, and the individual variance in this tendency was assessed with eye tracking using a face-distractor paradigm. The early RPs were related to a lower attention bias to fearful faces compared to happy and neutral faces after controlling for temperamental negative affectivity. This suggests that early RPs are related to the processing of emotional information later during infancy.  相似文献
