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

In the present study, the effect of food-related cues on the desire to eat chocolate in hungry and satiated subjects was investigated.
Subjects (n=46) were randomly assigned to either a hungry or satiated group and then assigned to a group receiving one of the following
stimuli: taste (2 M&Ms), sight (a photograph of M&Ms), cognition (a passage describin M&Ms), or control (no stimulus). In
each testing session, subjects rated their desire to eat chocolate before and after the 90-s presentation of the particular
stimulus. Each subject was then given a half pound of M&Ms so that actual consumption could also be measured. Results indicated
that, following the presentation of the sight and taste stimuli, the subjects’ desire to eat chocolate was significantly increased.
Furthermore, no differences in chocolate consumption due to state of hunger or type of food-related stimulus presented were
found. 相似文献

This study examined the influence of gender and various background factors on science anxiety. Students (50 women, 37 men) took the Science Anxiety Scale (Mallow, 1994), provided information about high school and college academic accomplishments, described gender-role stereotyping in the home, and evaluated their science teachers and science experiences. Most participants were Caucasian and from an upper-middle class background. Women were not uniformly more science anxious and had a relatively similar science background to men, although they had higher science grades in high school and did report less stringent sex-role socialization in the home. However, students with high science anxiety took fewer science courses in college, had lower SAT-Q scores, and reported that their high school science teachers were not helpful. The findings regarding gender- and anxiety-linked differences are discussed in terms of women's and men's differential interpretations of their abilities, the influence of parental gender typing on pursuit of science, and the gender-appropriateness of studying science. 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

Research indicates that in general, curiosity leads to more intense processing of an advertisement, which might result in a more skeptical response toward a persuasive message. However, we propose the opposite and argue that a process of evoking curiosity toward a stimulus in the first step (with the creation of an information gap) and resolving it in the second step creates a positive affective experience. Upon receiving curiosity-resolving information after becoming curious, consumers are less skeptical toward the advertised product, which leads to a more favorable attitude and a higher purchase intention. Based on four studies, we demonstrate curiosity's skepticism-reducing effect, its downstream consequences, and the underlying mechanism of positive affect. We show that this curiosity-stimulating way of information disclosure caused the effect instead of the information itself, which remained constant. The effects occur for integral curiosity, directed at the focal product, and for incidental curiosity, elicited by an unrelated stimulus. These results contribute to understanding consumer responses to curiosity-evoking advertisements, which are widespread, and provide implications for consumer psychologists, practitioners, and policy makers. 相似文献

The Personal Acquaintance Measure: a tool for appraising one's acquaintance with any person 总被引:1,自引:0,他引:1

The authors developed and evaluated the psychometric properties of the 18-item Personal Acquaintance Measure (PAM) and investigated how the PAM relates to self- other agreement in personality ratings. Results support that 6 factors represent the PAM (Duration, Frequency of Interaction, Knowledge of Goals, Physical Intimacy, Self-Disclosure, Social Network Familiarity), which showed evidence of internal consistency, test-retest reliability over 3 weeks, sensitivity to known group differences, discriminant validity from socially desirable responding, and convergent validity with other relationship inventories. Results also show that the PAM positively predicted self-other agreement. The authors discuss the implications of these findings for the PAM and research in person perception, although this measure may also be used in other research areas. 相似文献
