Bullying appears to be ubiquitous across cultures, involving hundreds of millions of adolescents worldwide, and has potentially serious negative consequences for its participants (particularly victims). We challenge the traditionally held belief that bullying results from maladaptive development by reviewing evidence that bullying may be, in part, an evolved, facultative, adaptive strategy that offers some benefits to its practitioners. In support of this view, we draw from research that suggests bullying serves to promote adolescent bullies' evolutionarily-relevant somatic, sexual, and dominance goals, has a genetic basis, and is widespread among nonhuman animals. We identify and explain differences in the bullying behavior of the two sexes, as well as when and why bullying is adaptive and when it may not be. We offer commentary on both the failures and successes of current anti-bullying interventions from an evolutionary perspective and suggest future directions for both research and anti-bullying interventions. 相似文献
Dementia diseases, especially Alzheimer’s disease (AD), are of considerable importance in terms of social policy and health economics. Moreover, against the background of the current Karlsruhe judgement on the legalisation of assisted suicide, there are also questions to be asked about medical humanities in AD.
Methodology
Relevant literature on complementary forms of therapy and prognosis was included and discussed.
Results
Creative sociotherapeutic approaches (art, music, dance) and validating psychotherapeutic approaches show promise for suitability and efficiency in the treatment of dementia, but in some cases still need to be scientifically tested. Biomarker-based early diagnosis of dementia diseases is increasingly becoming a subject of debate against the background of the Karlsruhe ruling.
Discussion
Needs-oriented and resource-enhancing approaches can make a significant contribution to improving the quality of life of people with dementia. The discussion on the issue of “assisted suicide” should include questions of the dignity and value of a life with dementia.
Outlook
The integrative dementia therapy model can be complemented by a religion- and spirituality-based approach. Appropriate forms of psychotherapy should be scientifically evaluated.
In the past 20 years, many studies in the cognitive neurosciences have analyzed human ability to navigate in recently learned and familiar environments by investigating the cognitive processes involved in successful navigation. In this study, we reviewed the main experimental paradigms and made a cognitive-oriented meta-analysis of fMRI studies of human navigation to underline the importance of the experimental designs and cognitive tasks used to assess navigational skills. We performed a general activation likelihood estimation (ALE) meta-analysis of 66 fMRI experiments to identify the neural substrates underpinning general aspects of human navigation. Four individual ALE analyses were performed to identify the neural substrates of different experimental paradigms (i.e., familiar vs. recently learned environments) and different navigational strategies (allocentric vs. egocentric). Results of the general ALE analysis highlighted a wide network of areas with clusters in the occipital, parietal, frontal and temporal lobes, especially in the parahippocampal cortex. Familiar environments seem to be processed by an extended temporal-frontal network, whereas recently learned environments require activation in the parahippocampal cortex and the parietal and occipital lobes. Allocentric strategy is subtended by the same areas as egocentric strategy, but the latter elicits greater activation in the right precuneus, middle occipital lobe and angular gyrus. Our results suggest that different neural correlates are involved in recalling a well-learned or recently acquired environment and that different networks of areas subtend egocentric and allocentric strategies. 相似文献
Father-child resemblance is increasingly attracting attention from researchers interested in studying paternal investment. The current study sought to determine whether a quasi-experimental infant massage intervention would increase father's perceptions of resemblance. The study included a dozen fathers in each of two groups: the first received an intensive series of lessons on infant-father massage along with their infants, while the second group served as a neutral control. We failed to find significant correlations between paternal investment and resemblance, but we found that fathers who participated in the infant massage intervention reported significantly larger post-study ratings of resemblance and lower ratings of paternal stress. This suggests that the relationship between father-child resemblance and paternal investment may be bidirectional. 相似文献
In the present paper, we aimed to provide evidence in support of the idea tested in a recent study by Lanciano and colleagues that flashbulb memories (FBMs) are a special class of autobiographical memories that can be assessed through the autobiographical implicit association test (aIAT). FBMs and event memories (EMs) for the news of the resignation of Pope Benedict XVI were evaluated in three samples of churchgoer Catholic, non-churchgoer Catholic and Evangelical Italian participants through the traditional self-report measures (specificity/accuracy, confidence, consistency) and aIAT indices. Results confirmed the strength of the association between FBM and true information. The aIAT effect was stronger for FBMs than for EM details, and for Catholic respondents who were the group most concerned by the original event. Furthermore, the use of implicit measures for memory assessment concurs with the traditional self-report indices of FBMs. The present evidence supports the idea that FBMs are special autobiographical memories which remain detailed, certain and consistent over time. 相似文献
Horizontal eye movement is an essential component of the psychological intervention “eye movement desensitization and reprocessing” (EMDR) used in posttraumatic stress disorder. A hypothesized mechanism of action is an overload of the visuospatial sketchpad and/or the phonological loop of the working memory. 相似文献
The aim of the present study was to uncover the temporal dynamics of face recognition as a function of reward. Event-related
potentials (ERPs) were recorded during the encoding and the subsequent old/new memory test in response to faces that could
be associated with a monetary reward. The behavioral results showed that faces associated with reward at both encoding and
retrieval were recognized better than the unrewarded ones. ERP responses highlighted that successful encoding predictive of
subsequent memory was greater for faces associated with reward than for faces without reward-driven motivational learning.
At retrieval, an early positive-going component was elicited for potentially rewarded faces on frontal regions, while the
occipito-temporal N170 component showed priming effects as a function of reward. Later on, larger centro-parietal ERP components,
related to recognition memory, were found selectively for reward-associated faces. Remarkably, electrophysiological responses
varied in a graded manner, with the largest amplitude yielded by faces with double reward, followed by faces associated with
reward only at encoding. Taken together, the present data show that the processing of outcome expectations affects face structural
encoding and increases memory efficiency, yielding a robust and sustained modulation over frontal and temporal areas where
reward and memory mechanisms operate in conjunction. 相似文献
The ability to imagine future events (episodic future thinking—EFT) emerges in preschoolers and further improves during middle childhood and adolescence. In the present study, we focused on the possible cognitive factors that affect EFT and its development. We assessed the ability to mentally project forward in time of a large cohort of 135 6- to 11-year-old children through a task with minimal narrative demands (the Picture Book Trip task adapted from Atance and Meltzoff in Cogn Dev 20(3):341–361. doi:10.1016/j.cogdev.2005.05.001, 2005) in order to avoid potential linguistic effects on children’s performance. The results showed that this task can be used to assess the development of EFT at least until the age of 8. Furthermore, EFT scores correlated with measures of phonological short-term and verbal working memory. These results support the possibility that cognitive factors such as working memory play a key role in EFT. 相似文献
