Freud (1933) suggested that women enter motherhood with a motivation to compensate for anatomical and psychological inferiority. This motivation is reflected in the desire to bear a son. Freud's idea was investigated by examining pregnant women's preferences regarding fetal gender and their emotional reactions (anxiety and depression) to information about fetal gender following an ultrasound examination and postpartum. Subjects were first-time and third-time pregnant women. In the third-time pregnant group only women who had two previous children of the same gender were investigated. First-time pregnant women did not express a predominant preference for any gender, third-time pregnant women preferred a child of a gender they did not have. In the first pregnancy, after the examination, subjects experienced a significant decrease in depression, and postpartum a significant elevation in both emotions. Preference and information about fetal gender affected depression only when they interacted with the time of measurement. In the third pregnancy, anxiety and depression were highest after the examination and the strongest elevation in both emotions was reported by women who had two sons, preferred a daughter and were informed they will deliver a son. The findings in both pregnancies put doubt on Freud's ideas about the motivation for motherhood, and suggest that social factors may also play a part in determining mother's attitude and emotional reactions towards fetal and neonate's gender. 相似文献

The contextual modulation of conditioned taste aversions by the physical environment and time of day is similar 下载免费PDF全文

In a pair of experiments, we have compared the ability of changes of place (Exp. 1) and changes of time of day (Exp. 2) to separately modulate learned saline-aversion memory phenomena in rats. Neither a spatial nor a temporal change disrupted latent inhibition using the present behavioral procedure. However, pre-exposure to the taste increased the contextual control of the learned aversion expression. The aversion reappeared in the place or at the time of conditioning after extinction in a different context. The results indicate that environmental and temporal contexts can independently, but similarly modulate taste aversion learning. 相似文献

Semantic categorization in the human brain: spatiotemporal dynamics revealed by magnetoencephalography 总被引:2,自引:0,他引:2

We examined the cortical representation of semantic categorization using magnetic source imaging in a task that revealed both dissociations among superordinate categories and associations among different base-level concepts within these categories. Around 200 ms after stimulus onset, the spatiotemporal correlation of brain activity elicited by base-level concepts was greater within than across superordinate categories in the right temporal lobe. Unsupervised clustering of data showed similar categorization between 210 and 450 ms mainly in the left hemisphere. This pattern suggests that well-defined semantic categories are represented in spatially distinct, macroscopically separable neural networks, independent of physical stimulus properties. In contrast, a broader, task-required categorization (natural/man-made) was not evident in our data. The perceptual dynamics of the categorization process is initially evident in the extrastriate areas of the right hemisphere; this activation is followed by higher-level activity along the ventral processing stream, implicating primarily the left temporal lobe. 相似文献

In analogy with Rousseau's concept of ‘civil religion’ as a system of ‘positive dogmas’, ‘without which’, as he observed, ‘a man cannot be a good citizen’, this paper advances the concept of ‘civil epistemology’ as the positive dogmas without which the agents of government actions cannot be held accountable by democratic citizens. The civil epistemology of democracy shapes the citizen's views on the nature of political reality, on how the facts of political reality can be known and by whom. Modern liberal democratic politics assumes that the exercise of political power can be manifest in a visible domain of publicly accessible facts. It rests on the Enlightenment faith in the powers of light and visibility to demystify political power, render political actors more exposed and therefore more honestly accountable and enlist the sense of sight as a vehicle of universal political participation. It is, in this context, that technology has come to play such an important symbolic role in the construction of the particular democratic genre of public action as a political spectacle. Democratic civil epistemology, and technology ‐ in the widest sense of the word ‐ as the prototype of action which can be observed in the field of visual perception, uphold the democratic conception of politics as a view. Together they define political actors as visible performers, journalists as observers (who translate actual seeing into virtual seeing) and the citizens as witnesses. 相似文献

The current study explored the relationship between religious coping and cumulative health risk associated with health behavior
patterns in a sample of 256 Latina and Caucasian female caregivers of elderly relatives with dementia. Primary analyses examined
the relationship between religious coping (both positive and negative) and an overall index of cumulative health risk. Secondary
analyses were conducted on the individual health behaviors subsumed in the broader index. Findings revealed that negative
religious coping was significantly associated with increased cumulative health risk. Positive religious coping was predictive
of decreased cumulative health risk among Latina caregivers but not among Caucasians. Negative religious coping was significantly
associated with both an increased likelihood for weight gain and increased dietary restriction. Positive religious coping
was associated with decreased likelihood for weight gain in Latinas. Implications for both caregivers and clinicians are discussed. 相似文献

We examined the factor structure of the Neuroticism scale of the Eysenck Personality Questionnaire (EPQ–R–N; S. B. G. Eysenck, Eysenck & Barrett, 1985) and its factor invariance across sex and racial/ethnic groups in a sample of 1,979 adolescents. Using confirmatory factor analyses, we compared a hierarchical model to previous models of the EPQ–R–N and to single-factor and 3-factor structures. The hierarchical factor structure in which a general factor coexists with 3 group factors (depression, social concerns, and worry) was superior to alternative models. The general factor accounted for more than 60% of the variance in EPQ–R–N total scores and was invariant across sex and ethnicity. The 3 group factors varied across ethnicity and sex. We discuss the implications of these findings for conceptualization and assessment of neuroticism using the EPQ–R–N. 相似文献

Intraspecific communication between mice takes place mainly via urinary chemosignals or "pheromones". Pheromones can influence aggressive and reproductive behavior as well as the neuroendocrine condition of the recipient female mice via their olfactory system. In this study, reproductively cyclic mice in the estrus phase were used to test intraspecific agonistic aggressive behavior. Data were obtained also on the count of the eggs shed in the oviducts. The results showed that (i) individually housed female mice are more aggressive toward an intruder female mouse than grouped mice, (ii) mice in which the vomeronasal organ was removed show aggressive behavior intermediate between individually housed and grouped mice, and (iii) a within group analysis did not show a positive correlation between aggression and presence of shed eggs in the oviducts. 相似文献

Words become associated following repeated co-occurrence episodes. This process might be further determined by the semantic characteristics of the words. The present study focused on how semantic and episodic factors interact in incidental formation of word associations. First, we found that human participants associate semantically related words more easily than unrelated words; this advantage increased linearly with repeated co-occurrence. Second, we developed a computational model, SEMANT, suggesting a possible mechanism for this semantic-episodic interaction. In SEMANT, episodic associations are implemented through lateral connections between nodes in a pre-existent self-organized map of word semantics. These connections are strengthened at each instance of concomitant activation, proportionally with the amount of the overlapping activity waves of activated nodes. In computer simulations SEMANT replicated the dynamics of associative learning in humans and led to testable predictions concerning normal associative learning as well as impaired learning in a diffuse semantic system like that characteristic of schizophrenia. 相似文献
