Selectivity in paternal and infanticidal responses by male mice: effects of relatedness, location, and previous sexual partners. 总被引:1,自引:0,他引:1
Male mice tend to be infanticidal to unrelated infants but parental to their own offspring. The present study examines three hypotheses that might explain this apparent discrimination. There was no evidence of selective infanticide toward infants encountered for the first time on the basis of kinship, location, or cues associated with previous sexual partners. However, males tended to direct more paternal responses toward their own unfamiliar infants than toward unrelated infants, infants encountered in the male's home cage than those in the cage of another male, and when cues associated with a previous sexual partner were present. Data suggested that the responses of females to male intruders might influence the responses of those males. It was concluded that the infanticidal responses of male mice are mediated by a particular state of the male but that males in a noninfanticidal state may vary their paternal responsiveness on the basis of direct and indirect cues concerning relatedness. 相似文献

The influential hypothesis that humans imitate from birth – and that this capacity is foundational to social cognition – is currently being challenged from several angles. Most prominently, the largest and most comprehensive longitudinal study of neonatal imitation to date failed to find evidence that neonates copied any of nine actions at any of four time points (Oostenbroek et al., [2016] Current Biology, 26, 1334–1338). The authors of an alternative and statistically liberal post‐hoc analysis of these same data (Meltzoff et al., [2017] Developmental Science, 21, e12609), however, concluded that the infants actually did imitate one of the nine actions: tongue protrusion. In line with the original intentions of this longitudinal study, we here report on whether individual differences in neonatal “imitation” predict later‐developing social cognitive behaviours. We measured a variety of social cognitive behaviours in a subset of the original sample of infants (N = 71) during the first 18 months: object‐directed imitation, joint attention, synchronous imitation and mirror self‐recognition. Results show that, even using the liberal operationalization, individual scores for neonatal “imitation” of tongue protrusion failed to predict any of the later‐developing social cognitive behaviours. The average Spearman correlation was close to zero, mean rs = 0.027, 95% CI [?0.020, 0.075], with all Bonferroni adjusted p values > .999. These results run counter to Meltzoff et al.'s rebuttal, and to the existence of a “like me” mechanism in neonates that is foundational to human social cognition. 相似文献

This study aimed at investigating the relationship between hours of homework, stress, and mood disturbance in senior high school students, 141 boys and 228 girls, recruited from high schools across Victoria, Australia. Participants' ages ranged from 16 to 18 years (M = 16.6, SD = .6). A 1-wk. homework diary, a Self-reported Stress scale, and the Profile of Mood States were administered to students. Analysis showed that the number of hours spent completing homework ranged from 10 to 65 hours per week (M = 37.0, SD = 12.2). Independent samples t-test analyses showed significant sex differences, with female students scoring higher on hours of homework, stress, and mood disturbance compared to male students. Pearson product-moment correlations were significant and positive for hours of homework with stress and for hours of homework with mood disturbance. 相似文献

Social interaction interventions for youth with severe disabilities should emphasize interdependence
An emphasis on independence may be limiting the outcomes achieved by social interaction research. Given the lack of correlation between intellectual or adaptive functioning level and meaningful social outcomes for people with severe disabilities, a focus on increasing skills as a mechanism for increasing social outcomes seems misplaced (or, at least, inefficient). It is argued here that a more productive route for researchers to follow will be to emphasize interdependence. Implications of such a focus will change where interventions are implemented, curricular foci, and the types of instructional strategies used to improve the social life of youth with severe disabilities.

The fields of genetics and neuroscience are yielding findings useful in understanding complex behavior-environment relations. We believe that these developments in interdisciplinary basic research are of interest to applied behavior analysts because of the long history of basic findings being used by the readership of the Journal of Applied Behavior Analysis to improve everyday human activities. An awareness of contemporary developments in a range of basic research disciplines may facilitate the systematic replication of those functional relations in applied settings. In this context, we selectively review papers published in the Journal of the Experimental Analysis of Behavior and other basic research journals that relate to gene-brain-behavior relations. 相似文献
