The ability to balance work and family demands can affect marital satisfaction, family cohesion, and job satisfaction. While most research in this area has utilized middle-class Anglo-American samples, the present investigation examined dual-earner, working-class Mexican- Americans. Positive relationships were found between work-family balance and satisfaction with marriage, family life and jobs with gender and acculturation showing moderating effects on some variables. Family therapists should be cognizant of the impact of work- family demands on marriage and family functioning even when working class minority families do not offer these issues as presenting problems. 相似文献

Mirror neurons are increasingly recognized as a crucial substrate for many developmental processes, including imitation and social learning. Although there has been considerable progress in describing their function and localization in the primate and adult human brain, we still know little about their ontogeny. The idea that mirror neurons result from Hebbian learning while the child observes/hears his/her own actions has received remarkable empirical support in recent years. Here we add a new element to this proposal, by suggesting that the infant's perceptual‐motor system is optimized to provide the brain with the correct input for Hebbian learning, thus facilitating the association between the perception of actions and their corresponding motor programs. We review evidence that infants (1) have a marked visual preference for hands, (2) show cyclic movement patterns with a frequency that could be in the optimal range for enhanced Hebbian learning, and (3) show synchronized theta EEG (also known to favour synaptic Hebbian learning) in mirror cortical areas during self‐observation of grasping. These conditions, taken together, would allow mirror neurons for manual actions to develop quickly and reliably through experiential canalization. Our hypothesis provides a plausible pathway for the emergence of mirror neurons that integrates learning with genetic pre‐programming, suggesting new avenues for research on the link between synaptic processes and behaviour in ontogeny. 相似文献

In the present fMRI study the issue of the specific cortices activation during imagery generation in different sensory modalities is addressed. In particular, we tested whether the vividness variability of imagery was reflected in the BOLD signal within specific sensory cortices. Subjects were asked to generate a mental image for each auditory presented sentence. Each imagery modality was contrasted with an abstract sentence condition. In addition, subjects were asked to fill the Italian version of the Questionnaire Upon Mental Imagery (QMI) prior to each neuroimaging session. In general, greater involvement of sensory specific cortices in high-vivid versus low-vivid subjects was found for visual (occipital), gustatory (anterior insula), kinaesthetic (pre-motor), and tactile and for somatic (post-central parietal) imagery modalities. These results support the hypothesis that vividness is related to image format: high-vivid subjects would create more analogical representations relying on the same specific neural substrates active during perception with respect to low-vivid subjects. Results are also discussed according to the simulation perspective. 相似文献

Honor has been an indispensable reference in the life of individuals and societies throughout the course of human history.
As a basic concern of men and women, the phenomenon already appears in the earliest literary testimonies. The heroes of the
Greek, Roman or German epic poems adapt their behavior to the demands of this particular deity, honor. Literature, at any
time, in any culture, in any language, makes constant use of honor as an effective dramatic element. The recurrent presence
is certainly a reflection of the actual significance the phenomenon of honor had in everyone’s life. This essay clarifies
why honor is given such importance; why it has been considered to be more valuable for the individual than his/her own life.
To this end, the mention of public opinion is unavoidable. This phenomenon, in its social psychological conception, is the
key that permits us to enlighten the labyrinth of honor. 相似文献

Acetylcholine-receptor blockers produce amnesia of aversively motivated behaviors. However, when animals are submitted to relatively high intensities of footshock (over-reinforcement), anticholinergic treatment does not induce memory impairments. The aim of this work was to determine whether the antiamnesic effect produced by increasing the magnitude of the negative reinforcer is gradually established or if a threshold should be reached to obtain such an effect. Wistar rats were trained in passive avoidance using 2.5, 2.6, 2.7, 2.8, 2.9 or 3.0 mA; 5 min after training they were given one systemic injection of scopolamine (8 mg/kg). An amnesic state was produced in the groups that were trained with the lower intensities (2.5-2.7 mA); with the three higher intensities near-perfect retention was evident. These results suggest that acetylcholine is critically involved in memory consolidation, and that by increasing the magnitude of the negative reinforcer, a threshold is reached where cholinergic activity of the nervous system is not necessary for the development of the consolidation process. 相似文献

Four-year results of a youth smoking prevention program using assertiveness training 总被引:2,自引:0,他引:2
Assertiveness training and its relationship to smoking behavior and how young adolescent boys and girls differ with respect to assertion was investigated. A total of 161 seventh-grade students from six health education classes participated. Two classes received an innovative smoking education program, two classes received assertiveness training plus an innovative smoking education program, and two classes received only the smoking education program usually offered by the school. Locus of control and levels of assertion and smoking behavior were assessed at pre- and posttest. The results indicate that boys are significantly more assertive than girls at age 12 (p = .0018), and this assertiveness increases equally over the next four years (p less than .0001). There were no significant differences in smoking behavior among the three groups; however, trends in smoking behavior in the desired direction were observed. There is no significant difference in smoking behavior between boys and girls. In this respect the sexes have reached equality, that is, girls are initiating cigarette smoking as frequently as are boys. Finally, there were no significant changes in assertion among the groups. It is concluded that the utility of assertiveness training for young adolescents is questionable. 相似文献

The reliability of the 30-item Modified Rathus Assertiveness Schedule (MRAS) was examined using the test-retest method over a three-week period. The MRAS, which was administered to 103 white middle-class seventh graders, yielded correlations of .74 using the Pearson product and Spearman Brown correlation coefficient. The correlations for males yielded .77 and .72 using the Pearson Product and Spearman Brown techniques, respectively. For females the correlations for both tests were .72. Paired t tests by sex indicated no significant change in MRAS scores between test administrations. These findings add to the existing information on the reliability of the MRAS. 相似文献
