The objective of this study is to analyze the mediating role of intrinsic and extrinsic job satisfaction in the relationship between the 2 dimensions of work-family conflict-family interfering with work (FIW) and work interfering with family (WIF)-and general job satisfaction. Step-by-step hierarchical regression analyses were carried out on a sample of 151 men and women from a Spanish public organization. The results confirmed the mediating role of intrinsic job satisfaction in the case of FIW. This highlights the importance of taking into account the level of satisfaction with the intrinsic facets of one's job as a measure for understanding why FIW has a negative impact on general job satisfaction. 相似文献

Generalization gradients have been investigated widely in animal conditioning experiments, but much less so in human predictive learning tasks. Here, we apply the experimental design of a recent study on conditioned fear generalization in humans (Lissek et al., 2008) to a predictive learning task, and examine the effects of a number of relevant procedural parameters drawn from the generalization literature in animal conditioning. Experiment 1 shows that prior discrimination learning and steady-state testing procedures sharpen the gradient; Experiment 2 shows that within-subjects testing of the range of generalization stimuli also sharpens the gradient. In addition, Experiment 2 shows that, in case of very flat initial generalization, an orderly gradient can reveal itself through differential rates of extinction learning. Finally, Experiment 2 also evidenced an orderly gradient of generalization-of-extinction. These results suggest that discrimination processes have an important effect on the generalization of predictive learning in humans, and highlight behavioral analogies between animal conditioning and human predictive learning. 相似文献

Two experiments examined the role of numerical distance in updating numerical information in working memory. In the first
experiment, participants had to memorize a new number only when it was smaller than a previously memorized number. In the
second experiment, updating was based on an external signal, which removed the need to perform any numerical comparison. In
both experiments, distance between the memorized number and the new one was manipulated. The results showed that smaller distances
between the new and the old information led to shorter updating times. This graded facilitation suggests that the process
by which information is substituted in the focus of attention involves maintaining the shared features between the new and
the old number activated and selecting other new features to be activated. Thus, the updating cost may be related to amount
of new features to be activated in the focus of attention. 相似文献

This paper describes an acculturative integration approach that stresses the contribution of liberation psychology. Immigrant integration is a challenge for receiving countries in the Western world due to the frequent asymmetrical and oppressive conditions suffered by newcomers in their new settlements. The cross-cultural perspective connects integration with psychological acculturation, emphasizing harmony between acquisitions of the new culture while maintaining cultural heritage, and creating opportunities for intergroup relationships. In turn, liberation psychology permits an understanding of the acculturative transition as an empowerment and self-construction process by which immigrants acquire a new vision of the world and of themselves, transforming both structural conditions and themselves. From this perspective we conceptualize acculturative integration as the process by which newcomers become an accepted part of the new society through a reflexive and evaluative process, changing their social references and position, rebuilding their social and personal resources, and achieving a new agency in coherence with their new challenges and goals. In this process, they acquire critical thinking about unequal conditions, gain capacities to respond to the inequalities, and take effective actions to confront them. We illustrate this process using the narratives of nine Moroccan women who are living in asymmetrical and oppressive local contexts in Andalusia, the southern-most region of Spain. 相似文献

Male aggressiveness is a complex behavior influenced by a number of genetic and non-genetic factors. Traditionally, the contribution of each of these factors has been established from experiments using artificially selected strains for high/low aggressive phenotypes. However, little is known about the factors underlying aggressive behavior in natural populations. In this study, we assess the influence of genetic background vs. postnatal maternal environment using a set of cross-fostering experiments between two wild-derived inbred strains, displaying high (STRA, derived from Mus musculus domesticus) and low (BUSNA, derived from Mus musculus musculus) levels of aggressiveness. The role of maternal environment was tested in males with the same genetic background (i.e. strain origin) reared under three different conditions: unfostered (weaned by mother), infostered (weaned by an unfamiliar dam from the same strain), and cross-fostered (weaned by a dam from a different strain). All males were tested against non-aggressive opponents from the A/J inbred strain. Resource-holding potential was assessed through body weight gains and territory ownership. The STRA males were shown to be aggressive in both neutral cage and resident-intruder tests. On the contrary, the BUSNA males were less aggressive in all tests. We did not find a significant effect of postnatal maternal environment; however, we detected significant maternal effect on body weight with differences between the strains, fostering type and interactions between these factors. We conclude that the aggressiveness preserved in the two strains has significant genetic component whose genetic basis can be dissected by quantitative trait loci analysis. 相似文献

The aim of this study was to analyze the extent to which the relations and the stability of the neonatal behaviour and the infant behaviour at both 4 and 12 months could be used to predict the infant temperament at 6 years. Seventy-two full-term, normal-weight, healthy children were followed from 3 days postpartum to 6 years. Neonatal behaviour at 3 and 30 days was assessed using the Neonatal Behaviour Assessment Scale (NBAS), behaviour at 4 and 12 months was assessed using the Infant Behaviour Record (IBR) from the Bayley Scales for Infant Development (BSID) and temperament at 6 years was assessed using the Dimensions of Temperament Survey-Revised (DOTS-R). Negative and positive affectivity and attention were the factors extracted from the behaviours of the IBR. Our results showed a low/moderate correlation between neonatal behaviour on the one hand and behaviour at 4 and 12 months and temperament at 6 years on the other hand. The motor performance, orientation and ANS stability of the neonate at 3 and 30 days were predictors of positive and negative affectivity at 4 months. State regulation and ANS stability at 3 days were predictors of negative affectivity and attention respectively at 12 months. Negative affectivity at 12 months and endurance at 30 days were predictors of general activity and persistence/attention at 6 years. Also, an inverse relation was found between state regulation at 30 days and general activity at 6 years, and a positive relation was found between attention at 4 months and persistence/attention at 6 years. We conclude that neonatal behaviour and behaviour in the first year of life are good predictors of temperament at 6 years and that early negative affectivity has an important role on infant temperament development. 相似文献

The aim of this study was to examine postural control in children with cerebral palsy performing a bilateral shoulder flexion to grasp a ball from a sitting posture. The participants were 12 typically developing children (control) without cerebral palsy and 12 children with cerebral palsy (CP). We analyzed the effect of ball mass (1 kg and 0.18 kg), postural adjustment (anticipatory, APA, and compensatory, CPA), and groups (control and CP) on the electrical activity of shoulder and trunk muscles with surface electromyography (EMG). Greater mean iEMG was seen in CPA, with heavy ball, and for posterior trunk muscles (p < .05). The children with CP presented the highest EMG and level of co-activation (p < .05). Linear regression indicated a positive relationship between EMG and aging for the control group, whereas that relationship was negative for participants with CP. We suggest that the main postural control strategy in children is based on corrections after the beginning of the movement. The linear relationship between EMG and aging suggests that postural control development is affected by central nervous disease which may lead to an increase in muscle co-activation. 相似文献

The results of this study are part of an investigation to determine whether the cognitive-emotional process of emotional recognition is deficient as a function of the clinical condition and alexithymia in subjects with somatization. This investigation applied the self-assessment of emotion and used a procedure that minimizes the use of verbal skills and verbal comprehension. The specific goal of this study was to verify whether there were differences in the covariation between alexithymia and self-evaluation of the emotional reaction in clinical and nonclinical subjects. The results of this study highlight the significant differences between clinical and control subjects. There were inverse significant correlations with the affective valence in clinical subjects, whereas in the ratings of the TAS-20 in control subjects, there were direct correlations with activation. In the conclusions, we discuss whether the variability of the results of previous research of the relationship between alexithymia and emotional recognition is a characteristic feature of this relationship or an effect of the different sampling and procedures utilized. 相似文献

The aim of this study was to evaluate a procedure to reveal the emergence of full naming in typically developing children. In Experiment 1, five 6-year-old children (a) learned tacts of pictures and the emergence of the selection of these pictures upon hearing their names was tested; and (b) the selection of other pictures was taught and the emergence of the tacts was tested. All children showed the emergence of picture selection and 3 children showed the emergence of the tacts. In Experiment 2a, the children's correct repetition of the names of 3 pictures was verified first, then the experimenter presented the pictures with their names without requiring any behavior other than attending. Finally, the emergence of picture selection and the tacts was tested. Experiment 2b replicated Experiment 2a with words that were easier to pronounce. Picture selection and the tacts emerged; this performance documented full naming for the first time with typically developing children. These procedures can be used to induce naming capacity in children who lack it; hence, they can be applied to teach children with learning delays. 相似文献
