Fourteen hundred and four mice from two inbred strains (Balb/c and C57BL/6), F1, F2, and backcrosses were subjected to four trials in a water-escape task and to a swimming test. Detailed analysis of mice behavior in these situations showed that the "F1 hybrid vigor" affected behavioral characters not directly related to physical vigor but of potential adaptive value. Their superiority was mainly due to more frequent adoption of an efficient behavioral tactic (direct or edge escape paths toward the exit) and more rapid progress with experience in this respect than other generations exhibited. These results clearly show that heterosis is not limited to physical vigor but may extend to behavioral and even psychological characters. 相似文献

The increasing number of asylum seekers and refugees in Europe calls for even more professionals to take care of refugees' mental health. Although different studies claim that migration could be a potential risk factor for self-harming behaviours, an in-depth exploration of the presence and characteristics of self-harm in the context of asylum is needed. In accordance with PRISMA guidelines, a systematic review was conducted across the databases Scopus, PubMed, Web of Knowledge and PsycArticles, regarding the main features of self-harming behaviour among refugees in Europe. Twelve articles and 3 main trajectories were identified: (1) A context at-risk: self-harm and detention centres; (2) A target at-risk: self-harm and unaccompanied minors; (3) A comparison between the mental health of asylum seekers and natives. Research on this topic in Europe is still underdeveloped and disorganised. Studies have mainly carried out wider quantitative investigations on mental health, usually overlapping self-harm with suicide. Detention centres emerged as the most widely investigated context and the one with the highest risk for self-harming behaviours. Instead, unaccompanied minors emerged as a particularly vulnerable category. Research in this field should be improved, combining quantitative and qualitative methods for a deeper understanding of the meanings of self-harm across cultures. 相似文献

How can servant leadership focused primarily on developing employees help them to become more ethical and prosocial, and to achieve positive results reaching beyond mere compliance with their tasks? More specifically, we propose that servant leadership may influence employees to engage in positive deviant behavior (PDB), meaning non-conforming behavior that is positive and ethical. Using self-determination theory (SDT), our research examines the effect of perceived servant leadership on the adoption of PDB by employees, mediated by basic psychological needs satisfaction and intrinsic motivation. To this end, we conducted a quantitative study of 344 French employees’ answers to an online survey. Structural equation modeling results indicated that the relationship between perceived servant leadership and innovative PDB is strongly predicted by SDT. Intrinsic motivation mediates the relationship between perceived servant leadership, satisfaction of basic psychological needs, and innovative PDB. Several limitations and implications will be discussed. 相似文献

In two experiments, we investigated memory for words location after writing a text. Experiment 1 demonstrated the existence
of a memory for words location in writing by showing that participants who first composed a text and were then asked to locate
words extracted from their text performed above a chance level established using a computer simulation, and better than participants
who did not compose a text but were told the subject of the text. Experiment 2 showed that memory for words location in writing
is mainly supported by a visuospatial representation of the text, as indicated by the lower recall of words location by participants
who performed a visuospatial concurrent task at the time of the composition, compared with participants who performed a verbal
concurrent task. The findings highlight the role of a spatial representation of the physical layout of the text and the role
of such a memory in the writing process.

Background Relatively little is known about the contribution of students' beliefs regarding the nature of academic ability (i.e. their implicit theories) on strategies used to deal with examinations. Aims This study applied Dweck's socio‐cognitive model of achievement motivation to better understand how students cope with examinations. It was expected that students' implicit theories of academic ability would be related to their use of particular coping strategies to deal with exam‐related stress. Additionally, it was predicted that perceived control over exams acts as a mediator between implicit theories of ability and coping. Sample Four hundred and ten undergraduate students (263 males, 147 females), aged from 17 to 26 years old (M = 19.73, SD = 1.46) were volunteers for the present study. Methods Students completed measures of coping, implicit theories of academic ability, and perception of control over academic examinations during regular classes in the first term of the university year. Results Multiple regression analyses revealed that incremental beliefs of ability significantly and positively predicted active coping, planning, venting of emotions, seeking social support for emotional and instrumental reasons, whereas entity beliefs positively predicted behavioural disengagement and negatively predicted active coping and acceptance. In addition, analyses revealed that entity beliefs of ability were related to coping strategies through students' perception of control over academic examinations. Conclusions These results confirm that exam‐related coping varies as a function of students' beliefs about the nature of academic ability and their perceptions of control when approaching examinations. 相似文献

A long history of examining reasoning using the Wason selection task has revealed that many respondents are biased towards choices that match the items expressed in the rule. One reason for this particular heuristic may be that no better information is immediately available, and thus matching items win over the competing choice simply via recognition. In two experiments, we sought to examine whether a stronger memory trace could override the matching bias. We created rules from common, easily recognisable nursery rhymes and varied the degree to which the presented rules matched the commonly known rhymes. The components of the remembered rhyme had a strong influence on the participants’ selections, suggesting that a strong memory trace can override the usual matching bias. We provide an interpretation of these results in light of answer fluency, mental models, and probabilistic estimates. 相似文献

康德谎言禁令认为任何时候都必须诚实,甚至在面对凶犯询问朋友藏身之处时也不能说假话,这引发了激烈争议。谎言的道德价值与说谎者的情境地位有本质关联:主动的、以骗取信任来获取利益的谎言是积极谎言,是谎言禁令所严格禁止的;被动的、避免伤害的谎言是消极谎言。消极谎言可以分为面对灾祸的与面对邪恶的两种情境。面对灾祸的谎言是善意谎言,出自避免伤害的动机;面对邪恶的被迫谎言不属于“蓄意的不真实”,而是严格意义的“被迫的不真实”;这不是为谎言辩护,而是为处于邪恶的逼迫之情境中弱者或受害者的生存权辩护。上述概念与真实的背离,是康德谎言禁令产生道德困惑与理论争议的根本原因。 相似文献
