In a previous study, Adachi, Kuwahata, Fujita, Tomonaga & Matsuzawa demonstrated that infant Japanese macaques (Macaca fuscata) form cross‐modal representations of conspecifics but not of humans. However, because the subjects in the experiment were raised in a large social group and had considerably less exposure to humans than to conspecifics, it was an open question whether their lack of cross‐modal representation of humans simply reflected their lower levels of exposure to humans or was caused by some innate restrictions on the ability. To answer the question, we used the same procedure but tested infant Japanese macaques with more extensive experience of humans in daily life. Briefly, we presented monkeys with a photograph of either a monkey or a human face on an LCD monitor after playing a vocalization of one of these two species. The subjects looked at the monitor longer when a voice and a face were mismatched than when they were matched, irrespective of whether the preceding vocalization was a monkey's or a human's. This suggests that once monkeys have extensive experience with humans, they will form a cross‐modal representation of humans as well as of conspecifics.  相似文献

IQs were correlated with the z score of suicide rate minus z score of homicide rate using nine regions of the world--established market economies, formerly socialized Europe, India, China, other Asian nations, Sub-Saharan Africa, Latin America/Caribbean, Middle East Crescent, and the USA. Correlations were .85 and .83 with crude rates and age-adjusted rates, respectively. The homicide findings are consistent with previous research in individual countries showing that less intelligent persons commit homicide more often. However, the present findings of a positive correlation between IQ and suicide rates are the opposite of what has been found in the more definitive studies within countries. Explanations for the apparent paradox and for the findings more generally were offered.  相似文献

Volunteering older adults plays a role in maintaining well-being through facilitation of face-to-face communication. However, the COVID-19 pandemic reduced volunteer opportunities involving physical interaction among seniors. While studies have reported that indirect communication such as non-face-to-face can support and improve mental health, it remains unclear whether it can substitute face-to-face communication among older volunteers accustomed to frequent interpersonal interactions. Therefore, the current study aimed to examine the relationship between communication forms and well-being during the pandemic by communication partner, among volunteers aged 65 years and above. Participants engaged in REPRINTS, which are volunteer who read picture books to children. At questionnaire survey was completed to investigate changes in the frequency of face-to-face and non-face-to-face communication before and during the pandemic, and well-being using the WHO-5. The results showed that maintaining or increasing the frequency of face-to-face communication with friends and neighbours before to during the pandemic was associated with a lower risk of being determined poor well-being (ORs: 0.465, 95% CI: 0.274–0.789, p = .004). This study demonstrated the significance of creating opportunities for face-to-face communication to maintain the well-being of older volunteers during the pandemic.  相似文献

Customers allowed to cocreate products are more willing to purchase them eventually because of not only their utilitarian but also their hedonic and experiential value. Experiential responses seem especially relevant in the cocreative consumption of cultural and intangible goods, such as music. To examine how such intangible aspects of cocreation can influence a consumer's intention to purchase, we let two groups of participants rate their experience consuming music in either a traditional or cocreative way, in an experimental situation inspired by the work of American rock band Nine Inch Nails. Participants in the traditional group had to passively watch a series of music videos; participants in the cocreative group were tasked to produce a video montage using the same material. In the traditional group, purchase intention was predicted by music quality, mediated by willingness to reexperience; in the cocreative group, however, purchase intention was only predicted by the consumers' experiential response, with no mediation of either music quality or willingness to reexperience. Additionally, the overall experiential response to music was lower in the cocreative group than in the traditional group, leading to lower intention to purchase. These results suggest that cocreated value for intangible goods is predicted at least as much by the consumers' experiential response as by their evaluation of product quality. It also suggests that there is nothing systematically positive in having consumers participate in the coproduction of intangible goods and that research is needed to identify the factors predicting the perceived quality of a cocreative experience.

Changing demographics indicate a significant increase in the number of surviving elderly, a decrease in the number of children in each family, and an increase in the number of surviving generations. Four guidelines are offered for minimizing the stress and maximizing the coping strategies of the elderly and their families: a) aging must be viewed as a life-span developmental experience, b) aging is a biopsychosocial phenomenon, c) supportive others can occupy critical positive or negative roles in the adaptation process, and d) the elderly and their families must develop proactive, anticipatory strategies for coping with the exigencies of age. These guidelines are offered to help the elderly face the challenge of aging successfully.  相似文献

Some types of stressor act on the immune system via the network comprising the endocrine-immune-nervous systems, and are reportedly responsible for the onset of diseases as well as giving impetus to their advance. It is important for the maintenance and promotion of health to cope with stress-induced changes in immunocompetence. Therefore, we studied the effects of administration of a novel biological response modifier (CM6271) derived from the mycelia of the basidiomycete Tricholoma matsutake on the NK cell activity in mice under restraint stress, in order to evaluate its potential to modulate immune responsiveness in stress-loaded individuals. (1) When C57BL/6 mice were restrained in 50-ml tubes for more than 6 h, splenic NK cell activity decreased significantly, but recovered gradually after the mice were released. The extent of the reduction of activity and the degree of recovery depended on the duration of the restraint. (2) The oral administration of CM6271 caused a significant acceleration of the recovery of the activity. This effect was dependent on the timing of administration and the dose given. (3) The administration of CM6271 had no clear effect on the blood levels of ACTH, corticosterone or lipid peroxide levels in the liver. These findings suggest that CM6271 promotes recovery from the decrease in NK cell activity induced by restraint stress.  相似文献

Acute mental stress is believed to induce transient arterial dysfunction, but relatively few data are available. We therefore examined the effect of mental stress tasks that could induce differential hemodynamic responses on arterial dysfunction. Forty‐eight participants conducted either a mental arithmetic (MA) task or a mirror‐tracing (MT) task. Cardiovascular indices and arterial stiffness were measured before, during, and after these tasks. Analysis revealed that increases in arterial stiffness during the task and during recovery were more pronounced for the MA than for the MT, and that evoked hemodynamic response was more myocardial for MA than for MT. These results clearly show that MA and MT tasks that induce differential hemodynamic responses have a differential effect on arterial stiffness. This finding sheds light on the underlying mechanism that may account for the relationship between cardiovascular reactivity and cardiovascular disease.  相似文献

Japanese is an SOV, head-final language with phonologically null arguments. Due to these characteristics, any (or all) of the arguments classified by a verb may be null. Consequently, verb argument information which Japanese readers/listeners receive overtly is sometimes incomplete. Furthermore, the arguments in a string may or may not belong to the same clause, and the disambiguating verb argument information does not become available until the end of a clause. These characteristics pose a question of whether or not verb argument information is a useful source of information for on-line syntactic processing in Japanese. An experiment using three types of complex NPs was designed specifically to examine whether Japanese readers use the argument structure information, or alternatively, they simply use minimal attachment in on-line processing of syntactically ambiguous structures. The reading times of three types of complex NPs suggest that native speakers of Japanese indeed utilize verb argument information, and they do so immediately. This finding supports the hypothesis that the Japanese language is processed in the similar way to English in that verb argument information functions as an important source of information in on-line processing. The difference between processing English and processing Japanese is that the former has a mechanism which keeps track of null arguments as well as overt ones.This research was supported in part by a grant to Mineharu Nakayama by the College of Humanitiesm The Ohio State University. A portion of this paper was presented at the CUNY Sentence Processing Conference (1992). I would like to thank Paul G. Gorrell, Julie E. Boland, Laurie A. Stowe, Mineharu Nakayama, and Jerry Packard for their useful comments and discussions.  相似文献

The Revised Chen Internet Addiction Scale (CIAS-R) was developed to assess Internet addiction in Chinese populations, but its psychometric properties in adolescents have not been examined. This study aimed to evaluate the factor structure and psychometric properties of CIAS-R in Hong Kong Chinese adolescents. 860 Grade 7 to 13 students (38 % boys) completed the CIAS-R, the Young’s Internet Addiction Test (IAT), and the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) in a survey. The prevalence of Internet addiction as assessed by CIAS-R was 18 %. High internal consistency and inter-item correlations were reported for the CIAS-R. Results from the confirmatory factor analysis suggested a four-factor structure of Compulsive Use and Withdrawal, Tolerance, Interpersonal and Health-related Problems, and Time Management Problems. Moreover, results of hierarchical multiple regression supported the incremental validity of the CIAS-R to predict mental health outcomes beyond the effects of demographic differences and self-reported time spent online. The CIAS is a reliable and valid measure of internet addiction problems in Hong Kong adolescents. Future study is warranted to validate the cutoffs of the CIAS-R for identification of adolescents with Internet use problems who may have mental health needs.  相似文献
