This article deals with relationships and marriages of the Tlingit with immigrants from the Russian Empire as well as with representatives of other European and non-European peoples during the period when Alaska belonged to the Russian Empire. Matrimonial relations existed in two variants: legal, sanctified by the church, and in the form of permanent extramarital cohabitation or casual relationships. The latter variant absolutely predominated. With this, there was a sharply reflected gender imbalance, since men absolutely predominated among the immigrants, and therefore Tlingit women emerged in the role of marriage partners in the overwhelming majority of cases. A directly opposite pattern was observed in Tlingit contacts with the Athapaskans and to some extent with the Eyak. Matrimonial connections exerted influence on the workings of the Russian colonization, stimulated growth in mixed populations, and facilitated gradual acculturation of the Tlingit, along with contributing to the expansion of their ethnic territory. 相似文献

Comorbidity rates between ADHD and anxiety disorders (AD) are high, but little is known about the nature of this co-occurrence. A dominant idea is that AD may intensify some (i.e., attention and working memory) and attenuate other (i.e., inhibition) ADHD symptoms. Results are mixed, potentially because of between-study differences. To investigate this further we performed a meta-regression analysis on 11 studies (n ‘ADHD-only’ = 695; n ‘ADHD + AD’ = 608), containing 35 effect sizes on attention, inhibition and working memory. Main results were: (1) no evidence of a negative effect of AD on attention and working memory; (2) better response inhibition in children with ADHD with AD than those with only ADHD (medium ES g = ? .40); (3) medication moderated this association: the effect seemed limited to studies that included medication-naïve participants; (4) the difference between the two groups increased with age for attention and with proportion of boys for working memory ability. There was no effect of comorbid disruptive behavior disorder. In conclusion, AD seems to be a protective factor for inhibition problems as assessed with laboratory tasks in ADHD, especially in children who are medication naïve. Further, AD may have a protective function for attention in older children, and for working memory in boys with ADHD. It is therefore important to screen for AD when diagnosing ADHD, and to educate those with comorbid AD about the possible positive function of feeling anxious. Potential negative effects of ADHD medication on inhibition in children with comorbid AD should be considered. 相似文献

Studying memory in infants can be challenging, as they cannot express their subjective recollection verbally. In this study we use a novel method with which we can assess episodic recognition memory through pupillometry, using identical procedures and stimuli for infants and adults. In three experiments of 4‐ and 7‐month‐old infants, and adults we show that the adult pupillary response is larger to previously seen than to never seen items (old/new effect). Pupil dilations index subjective memory experience in adults, producing distinct pupil dilations to items judged as remembered, familiar, and new, regardless of actual previous exposure (Experiment 1). Seven‐month‐old infants demonstrate a clear pupillary old/new effect, very similar to that of adults (Experiment 2), whereas 4‐month‐olds do not demonstrate such an effect (Experiment 3). Our findings suggest that the mnemonic mechanisms that serve infants' and adults' episodic recognition memory are more similar than previously asserted: they are not fully developed at 4 months of age but that there is contiguity in human episodic memory development from 7 months of age. 相似文献

Recent evidence suggests division of labor in phonological analysis underlying speech recognition. Adults and children appear to decompose the speech stream into phoneme‐relevant information and into syllable stress. Here we investigate whether both speech processing streams develop from a common path in infancy, or whether there are two separate streams from early on. We presented stressed and unstressed syllables (spoken primes) followed by initially stressed early learned disyllabic German words (spoken targets). Stress overlap and phoneme overlap between the primes and the initial syllable of the targets varied orthogonally. We tested infants 3, 6 and 9 months after birth. Event‐related potentials (ERPs) revealed stress priming without phoneme priming in the 3‐month‐olds; phoneme priming without stress priming in the 6‐month‐olds; and phoneme priming, stress priming as well as an interaction of both in 9‐month‐olds. In general the present findings reveal that infants start with separate processing streams related to syllable stress and to phoneme‐relevant information; and that they need to learn to merge both aspects of speech processing. In particular the present results suggest (i) that phoneme‐free prosodic processing dominates in early infancy; (ii) that prosody‐free phoneme processing dominates in middle infancy; and (iii) that both types of processing are operating in parallel and can be merged in late infancy. 相似文献

Dental education programs are known to be highly stressful and stress can affect general health. The aims were to identify sources of stress among preclinical students and to evaluate their perceived levels of stress, self-efficacy and effective coping strategies in a private dental school. One hundred preclinical students in a Turkish private dental school were surveyed using dental environment stress (DES), perceived stress (PSS), general self-efficacy (G-SES) and brief coping scales (Brief-COPE). Age, gender, history of psychiatric treatment, factors that affected the choice of dentistry, choice rank of dental school, scholarship and income was recorded. ‘Exams and grades’ followed by ‘Fear of failing course or year’ were found to be the most stressprovoking factors. The most and the least stressprovoking DES domains were ‘Workload’ and ‘Social stressors’, respectively. ‘Social stressors’ affected male more than female (p < .05). The most and the least common coping strategies were found to be ‘Planning’, and ‘Drug’, respectively. Female used ‘Instrumental support’ more than male (p < .05). Demographic factors had impact on the perceived stress factors and levels, as well as coping strategies. Unlike previous studies establishing high stress levels in dental students, preclinical students displayed moderate level of stress. Clinical dental education might be more responsible for creating stress. 相似文献

Animate entities are often better remembered than inanimate ones. The proximal mechanisms underlying this animacy effect on recall are unclear. In two experiments, we tested whether the animacy effect is due to emotional arousal. Experiment 1 revealed that translations of the animate words used in the pioneering study of Nairne et al. (Psychological science, 24, 2099–2105, 2013) were perceived as being more arousing than translations of the inanimate words, suggesting that animacy might have been confounded with arousal in previous studies. In Experiment 2, new word lists were created in which the animate and inanimate words were matched on arousal (amongst several other dimensions), and participants were required to reproduce the animate and inanimate words in a free recall task. There was a tendency towards better memory for arousing items, but robust animacy effects were obtained even though animate and inanimate words were matched on arousal. Thus, while arousal may contribute to the animacy effect when it is not carefully controlled for, it cannot explain the memory advantage of animate items. 相似文献

When students are faced with the decision of whether to assist a peer, they should be sensitive to the potential risks associated with doing so. Two factors associated with risky helping behaviour in the classroom are: (1) the grading practices that are used, and (2) knowledge of a peer’s relative status. Normative (“curved”) grading creates a situation in which peer-interactions are potentially competitive, but it is only those interactions with peers of a similar status that carry the potential for assistance to be costly to oneself. In two studies, we created hypothetical scenarios in which the grading practices (normative or absolute) and peer-status proximity (proximate, distant, or unknown) were manipulated, and asked participants to report their willingness to cooperate with a peer by sharing their notes from an important lecture. We found that when normative grading was used, individuals were less willing to assist a peer when they knew that the peer’s status was proximate to their own. There was also less cooperation when peer status was unknown, under normative grading, which is consistent with a risk-aversion tendency. 相似文献

Cases like that of John Howard Yoder – a pacifist theorist who perpetrated sexual violence – raise difficult questions about teaching material implicated in traumatic pasts. This paper argues that “moral injury” provides a useful framework for understanding the dynamics of teaching prominent cases of tainted legacies like Yoder's and for developing best pedagogical practices across the field of religious ethics. The moral injury framework empowers students to think critically and self‐reflectively about authority, conceptions of the good, the various stakes for different persons and communities in social issues, and the need for moral repair. It establishes the importance of professor and student preparation; propels students into the moral questioning and analysis that constitutes “ethics”; draws attention to the connections between and intersectionality of various moral problems while also attending to important moral distinctions; and affords opportunities to study individual and institutional efforts at moral repair. 相似文献

Academic self-handicapping is a very popular subject of research in educational psychology, in which a growing number of related findings are reported. However, apart from a recent meta-analysis (Schwinger et al. in J Educ Psychol 106(3):744–761, 2014), the last comprehensive review of the subject was published 17 years ago (Urdan and Midgley in Educ Psychol Rev 13(2):115–138, 2001). This paper integrates relevant findings accumulated since then, which are discussed in a coherent interpretive framework. The first part of the paper discusses the definition and theoretical grounds of academic self-handicapping, then its manifestations in an academic context are enumerated. The second part of the study focuses on the self-protective function of stereotypes based on self-handicapping as well as on the impressions self-handicapping students may make on others at school. A summary of the contributions of goal orientation theory is provided in relation to self-handicapping, and the effects of various goal orientations and goal structures on academic performance are analysed. Based on an analysis of interactions between self-handicapping and academic performance, the authors argue for the importance of prevention and suggest possible ways to prevent self-handicapping. In conclusion, measurement issues of academic self-handicapping and the methodological paradox inherent in questionnaire measures are discussed. 相似文献

A popular strategy for meeting over-determination and pre-emption challenges to the comparative counterfactual conception of harm is Derek Parfit’s suggestion, more recently defended by Neil Feit, that a plurality of events harms A if and only if that plurality is the smallest plurality of events such that, if none of them had occurred, A would have been better off. This analysis of ‘harm’ rests on a simple but natural mistake about the relevant counterfactual comparison. Pluralities fulfilling these conditions make no difference to the worse for anyone in the over-determination cases that prompted the need for revising the comparative conception of harm to begin with. We may choose to call them harmful anyway, but then we must abandon the idea that making a difference to the worse for someone is essential to harming. I argue that we should hold on to the difference-making criterion and give up the plural harm principle. I offer an explanation of why Parfit’s and Feit’s plural harm approach seems attractive. Finally, I argue that the consequences of giving up the plural harm principle and holding on to the simple comparative counterfactual analysis of harm are less radical than we may think, in relation to questions about wrongness and responsibility. 相似文献
