Comparative experimental studies of imitative learning have focused mainly on primates and birds. However, cetaceans are promising candidates to display imitative learning as they have evolved in socioecological settings that have selected for large brains, complex sociality, and coordinated predatory tactics. Here we tested imitative learning in killer whales, Orcinus orca. We used a ‘do-as-other-does’ paradigm in which 3 subjects witnessed a conspecific demonstrator’s performance that included 15 familiar and 4 novel behaviours. The three subjects (1) learned the copy command signal ‘Do that’ very quickly, that is, 20 trials on average; (2) copied 100 % of the demonstrator’s familiar and novel actions; (3) achieved full matches in the first attempt for 8–13 familiar behaviours (out of 15) and for the 2 novel behaviours (out of 2) in one subject; and (4) took no longer than 8 trials to accurately copy any familiar behaviour, and no longer than 16 trials to copy any novel behaviour. This study provides experimental evidence for body imitation, including production imitation, in killer whales that is comparable to that observed in dolphins tested under similar conditions. These findings suggest that imitative learning may underpin some of the group-specific traditions reported in killer whales in the field. 相似文献

This study measures and compares the level of congruency between male sexual orientation and gender identification using the Kinsey Scale in three cultures: Brazil (Florianópolis), Turkey (Istanbul) and Thailand (Bangkok) with social class as the control mechanism. Quantitative techniques are utilized in comparing the self-evaluation of sexual orientation and gender identification among young men with same-sex, opposite-sex and both-sex orientations or behaviors. Results: In all three cultures, homosexuals were much more likely than bisexuals or heterosexuals to enjoy receiving anal sex and performing fellatio. Bisexual and heterosexual men, as expected, reported enjoying vaginal penetration and cunnilingus more than homosexual men. Same-sex oriented male self-evaluations of homosexual orientation and feminine gender identification scored similarly on the Kinsey Scale (0–6) in all three countries. These data support the traditional identity trichotomy used in the field: homosexuality, bisexuality and heterosexuality. When controlling for nationality only small differences were found amongst the participants; however, social class or level of education did have a significant effect on the relationship between self-evaluation of sexual orientation and gender identification. 相似文献

In this paper I revisit Gregory Kavka’s Toxin Puzzle and propose a novel solution to it. Like some previous accounts, mine postulates a tight link between intentions and reasons but, unlike them, in my account these are motivating rather than normative reasons, i.e. reasons that explain (rather than justify) the intended action. I argue that sensitivity to the absence of possible motivational explanations for the intended action is constitutive of deliberation-based intentions. Since ordinary rational agents display this sensitivity, when placed in the toxin scenario they will believe that there is no motivational explanation for actually drinking the toxin and this is why they can’t form the intention to drink it in the first place. I thus argue that my Motivating-Explanatory Reason Principle correctly explains the toxin puzzle, thereby revealing itself as a genuine metaphysical constraint on intentions. I also explore at length the implications of my account for the nature of intention and rational agency. 相似文献

This study aimed to understand the nature of nurturing and restraining relationships in a school communiy. The inquiry entailed a single instrumental case study of a selected school community in a semi-urban context in South Africa. Participants were learners (n=720), teachers (n=33) and administrative and terrain staff members (N=8) as well as two parents. Data on participants' perceptions of relationships in the school community were collected using work sessions/nominal group techniques, visual representations, and focus group interviews. Thematic analysis of the data revealed connectedness, respect, care and transparent communication as aspects that nurture relationships. Limited connectedness between people, the abuse of power, shifting of responsibility and disrespect for one another were revealed as aspects that restrain relationships. 相似文献

The goal of this study was to analyze the relationships to be found among stigma perception, active and avoidant coping strategies, and subjective and psychological well-being in a sample of 133 people with HIV. The results showed that stigma perception and avoidant coping strategies (venting, self-blame, denial, behavioural disengagement and substance use) were positively associated, whereas, both stigma perception and avoidant coping were negatively associated with different measures of well-being (affect balance, self-acceptance and environmental mastery). These negative relationships between stigma perception and the three well-being measures were mediated by the use of avoidant coping strategies. Results suggest that psychosocial intervention programs for people who report psychological distress arising from prejudice must be aimed at developing appropriate ways to deal with this prejudice. Intervention programs should also include strategies to directly increase well-being since from a positive psychology viewpoint certain interventions have been shown to do so, and HIV research has also shown that well-being is associated with lower mortality rates. 相似文献

The amount of information attached to a noun phrase (henceforth, NP) has been shown to enhance accessibility and increase pronominal reference in language production. However, both the effect of information quantity on the comprehension of ambiguous pronouns and the time course of any informativity effect have been left unexplored. In two eyetracking experiments, we investigated how additional information on the part of NP referents influenced the resolution of following ambiguous pronouns. The results of the first experiment revealed an informativity effect, with more looks to the informationally richer referent than to the competitor. However, the effect of additional information emerged late in time when the referent was the object of the verb. The second experiment replicated the results of the first and also showed that, consistent with the online results, an ambiguous pronoun is interpreted as referring to the informationally richer NP in an offline, explicit pronoun resolution task. The results lend support to theories of language processing that assume that explicit information increases the accessibility of the associated concept, in contrast to approaches that assume that accessibility is associated with givenness. 相似文献

This study explored the relationship between employees’ employability capacities and their organisational commitment foci. A convenience sample of 196 South African human resource professionals participated in the study, consisting of 73% females and 88% black African people, predominantly within their early career stages (aged > 45 years). Data on individuals’ employability capacities and organisational commitment were collected via questionnaires. Canonical correlation analysis (CCA) was performed to assess the association between the variables of employability capacities and organisational commitment foci. Participants’ lifelong learning capacities (goal-directed behaviour and continuous learning orientation) were positively associated with their career commitment. This finding suggests that a strong lifelong orientation is likely to increase involvement in one’s occupation within the organisation, which contributes to organisational commitment. Lifelong learning capacities appear important to human resource professionals’ career development within their employer organisation. 相似文献

This experiment investigated contextual diversity effects on novel word learning in English as a second language (L2). A group of advanced English speakers, whose native language was Spanish, participated in the study. Participants learned the meaning of real but obscure words that were embedded in either two or 12 different sentences and learned over two days (frequency of exposure was kept constant). On day three, participants were tested using reading aloud and semantic decision tasks. The results showed that participants learned the meaning of words in both conditions fairly well as revealed by their accuracy in the semantic decision task. However, words experienced in 12 different contexts generated more accurate and faster reaction times (RTs), suggesting the acquisition of more robust semantic representations. Strikingly, reading latencies were also faster for the 12-sentence condition, which might imply that semantics has an effect on reading newly learned words in English as a second language. These results are discussed and accommodated in view of the DRC and the PDP models of single-word reading. 相似文献
