Genetic Influence Helps Explain Variation in Human Fertility: Evidence From Recent Behavioral and Molecular Genetic Studies 总被引:1,自引:0,他引:1

To search for genetic influence on human fertility differentials appears inconsistent with past empirical research and prior interpretations of Fisher's fundamental theorem of natural selection. We discuss Fisher's theorem and give reasons why genetic influences may indeed account for individual differences in human fertility. We review recent empirical studies showing genetic influence on variance in fertility outcomes and precursors to fertility. Further, some of the genetic variance underlying fertility outcomes overlaps with that underlying fertility precursors. Findings from different cultures, different times, different levels of data, and both behavioral and molecular genetic designs lead to the same conclusion: Fertility differentials are genetically influenced, and at least part of the influence derives from behavioral precursors that are under volitional control, which are themselves genetically mediated. 相似文献

With data gathered from 96 female college students, intercorrelations were examined among self-concept ratings of masculinity and femininity, and scales from two personality-trait measures of masculinity and femininity—the Adjective Check List (ACL) and the Extended Personal Attributes Questionnaire (EPAQ). The sign and magnitude of the correlations between pairs of measures were successfully predicted on the basis of the congruence between measures of both the gender relevance and the desirability of the self-rated traits comprising each measure. The desirability of the trait items employed in self-report personality-trait scales of masculinity and femininity evidently introduces methods variance that can either inhibit or potentiate the relationship with other scales composed predominantly of either desirable or undesirable traits. When balanced for the desirability of trait items, personality-trait scores of masculinity and femininity were substantially inversely correlated with each other, and only marginally correlated with self-concept ratings of masculinity and femininity, but these correlations remained in the anticipated directions. This result is consistent with the findings of Pedhazur and Tetenbaum (“Bem Sex Role Inventory: A Theoretical and Methodological Critique,” Journal of Personality and Social Psychology, 1979, 37, 996–1016), and supports Spence's (Masculinity, Femininity, and Gender-Related Traits: A Conceptual Analysis and Critique of Current Research,” In B. A. Maher and W. B. Maher (Eds.), Progress in Experimental Research, Vol. XIII, Normal Personality Processes, New York: Academic Press, 1984) position that personality traits should be viewed as only one of many possible referents for gender/sex role identity. 相似文献

Nineteen of 27 patients suffering from Irritable Bowel Syndrome (IBS) who had completed a multicomponent treatment involving progressive muscle relaxation, thermal biofeedback, cognitive therapy and IBS education were located and evaluated 4 yr posttreatment. Seventeen of 19 (89.5, or 63% of the total original sample) rated themselves as more than 50% improved. Six of the 12 patients (50%) who submitted symptom monitoring diaries met our criteria for clinical improvement, i.e. achieving at least a 50% reduction in primary IBS symptom scores. The means on all measures at long-term follow-up were lower than those obtained prior to treatment. When follow-up symptom means were compared with pretreatment means, significant (P less than 0.05) reductions were obtained on abdominal pain/tenderness, diarrhea, nausea, and flatulence. 相似文献

Aplysia fasciata attempt to bite and swallow food wrapped in a plastic net, tasting food through holes in the net. Net-enclosed food cannot be swallowed, and becomes cyclically lodged and pushed out of the buccal cavity. Aplysia gradually modify their response to this food, and eventually cease to respond. Twenty-four hours following training, memory is maintained, as shown by savings upon retraining. An essential component of the behavioral plasticity is food becoming stuck within the buccal cavity: when the lips are stimulated without allowing food to enter the buccal cavity, animals stop responding, but training takes longer, and memory is not retained. Savings upon retraining are contingent upon temporal pairing of food upon the lips and stimuli from within the buccal cavity: when lip stimuli and the experience of food stuck within the buccal cavity occur sequentially (rather than simultaneously), 24 hr later, animals are not significantly different from naive subjects. 相似文献

This article presents a random walk model that can be analyzed without recourse to Wald's (1947) approximation, which neglects the excess over the absorbing barriers. Hence, the model yields exact predictions for the absorption probabilities and all mean conditional absorption times. We derive these predictions in some detail and fit them to the extensive data of an identification experiment published by Green et al. (1983). The fit of the model seems satisfactory. The relationship of the model to existing classes of random walk models (SPRT and SSR; see Luce, 1986) is discussed; for certain combinations of its parameters, the model belongs either to the SPRT or to the SSR class, or to both. We stress the theoretical significance of the knowledge of exact results for the evaluation of Wald's approximation and general properties of the several models proposed derived from this approximation. 相似文献

Various field studies and experimental simulations demonstrated that causal reasoning increases after unexpected as well as after unpleasant events. However, unpleasant events are seen as less likely than pleasant ones in everyday life. Accordingly, the subjective probability of the event and its hedonic quality were naturally confounded in these studies. To isolate the contribution of both determinants, the subjective probability and the valence of an event were independently manipulated in a laboratory experiment. Subjects completed an ostensible ‘professional skills test’ and received either success or failure feedback in relation to a criterion set by the experimenter. The subjective probability of success was varied by informing subjects about the distribution of success and failure in a comparable population (either 23 per cent or 77 per cent were said to meet the criterion). The results indicate a pronounced valence effect: The intensity of causal reasoning and the number of possible reasons reported for the outcome was greater after negative than after positive feedback, independent of the a priori probability of the outcome. No evidence for an increase in causal explanations after unexpected, as compared to expected, events was obtained. Several mediating processes are discussed. 相似文献
