200 pairs of twins were assessed at 14 months of age in the laboratory and home. Measures were obtained of temperament, emotion, and cognition/language. Comparisons between identical and fraternal twin correlations suggest that individual differences are due in part to heritable influences. For temperament, genetic influence was significant for behavioral observations of inhibition to the unfamiliar, tester ratings of activity, and parental ratings of temperament. For emotion, significant genetic influence was found for empathy and parental ratings of negative emotion. The estimate of heritability for parental report of expression of negative emotions was relatively high, whereas that for expression of positive emotions was low, a finding consistent with previous research. For cognition and language, genetic influence was significant for behavioral indices of spatial memory, categorization, and word comprehension. Shared rearing environment appears influential for parental reports of language and for positive emotions, but not for other measures of emotion or for temperament. 相似文献

This paper looks at access to adult education and vocational education and training (VET) provision in fishing communities in the Western Cape, South Africa. Fishing communities are being disadvantaged due to geographical and socio-political marginalisation, and the predominance of informal sector employment in the context of worldwide marine resource depletion. Neither public nor private provision is adequately serving rural areas or the informal sector in this context. Using the sustainable livelihoods approach as a tool of analysis, this paper argues that a more cross-sectoral approach is needed to tackle equity and poverty concerns in adult education and training provision. 相似文献

In 2 experiments we asked whether training in multiple contexts could eliminate context-dependent memory retrieval at 6 months as it does for adults. We found that 24-hour retention was disrupted when infants were trained in one context and tested in another but not when they were trained in multiple contexts prior to testing in a novel context (Experiment 1). After a long delay, however, training in multiple contexts did not facilitate memory retrieval in a novel context: An otherwise effective retrieval cue (the training mobile) did not alleviate forgetting 3 weeks later when it was presented in a novel context (Experiment 2). These findings demonstrate that multiple learning contexts can override the debilitating effects of an altered context on memory retrieval at 6 months, but only over the short term. The resistance of older memories to retrieval in novel contexts after long periods of disuse may be adaptive, insuring that potentially inappropriate or irrelevant memories will not be expressed. 相似文献

72 children, ages 6 to 11 years, were presented with a series of stories involving psychological harm (name-calling) in a game context. Situations were presented in which intentions, consequences, and game context were varied, along with order of story presentation. Comparisons between acts of physical and psychological harm were also conducted. Although responses in some conditions were influenced by order of presentation, age differences were found in children's evaluations of agents' actions and recipients' reactions for psychological harm in game contexts. Younger children were more likely to ignore intentions and consequences or the recipient's perspective and to focus on contextual features (e.g., game rules). Older children were more likely to base their evaluations on intentions, or both intentions and consequences, and to take into account the recipient's perspective. Game context interacted differentially with psychological and physical harm at all ages. Evaluations of acts of physical harm were more likely than acts of psychological harm to be transformed by game context. 相似文献

Concepts associated with the equality symbol 总被引:1,自引:0,他引:1

This paper looks at recent research dealing with uses of the equal sign and underlying notions of equivalence or non-equivalence among preschoolers (their intuitive nitions of equality), elementary and secondary school children, and college students. The idea that the equal sign is a do something signal (an operator symbol) persists throughout elementary school and even into junior high school. High schoolers' use of the equal sign in algebraic equations as a symbol for equivalence may be concealing a fairly tenuous grasp of the underlying relationship between the equal sign and the notion of equivalence, as indicated by some of the shortcut errors they make when solving equations.This article is based on a paper presented at Fourth International Conference of the International Group for the Psychology of Mathematics Education, Berkeley, California, August 1980.

The specificity of memory retrieval by 3-month-old infants was examined in 3 experiments. All infants were trained in the mobile conjugate reinforcement paradigm to kick their feet to produce movement in an overhead crib mobile and were tested 2 weeks later. 24 hours prior to the test, subjects received a 3-min reminder treatment. The results of Experiment 1 demonstrated that only the moving training mobile alleviated forgetting after the 2-week retention interval; forgetting was not alleviated by exposure to the stationary training mobile or to the mobile stands and ribbon alone. The results of Experiments 2 and 3 demonstrated that, once retrieved, the reactivated memory was highly specific to the conditions of original training. Furthermore, the memory attributes that were the last to be forgotten (e.g., the general or global features) were the first to be retrieved following the reminder treatment. Conversely, those memory attributes that were forgotten first (e.g., the specific or local details) were the last to be retrieved. These findings have important implications for infant memory retrieval, reminiscence, and infantile amnesia. 相似文献

‘Laddish’ attitudes and behaviours are central to current discourses on boys’ ‘underachievement’, as they are seen by many people to impede the progress of some boys in school. Whilst the vast majority of concern about ‘laddishness’ has, to date, focused upon boys, according to media reports there are now good reasons to worry about girls. Anecdotes from teachers and reports in the media suggest that some schoolgirls are now acting ‘laddishly’, that they are ‘ladettes’. This paper explores ‘ladette’ cultures in secondary schools, drawing upon interview data from100 pupils and 30 teachers. It tackles and discusses the following questions: (a) What does the term ‘ladette’ mean to pupils and teachers? (b) Do school‐aged ‘ladettes’ ‘exist’—and if so, what are they like inside and outside of school? (c) In what ways are ‘ladettes’ similar to, and different from, ‘lads’? (d) Are teachers concerned about ‘ladettes’? (e) Are ‘ladette’ behaviours on the increase? 相似文献
