This study examined infants' abilities to separate speech from different talkers and to recognize a familiar word (the infant's own name) in the context of noise. In 4 experiments, infants heard repetitions of either their names or unfamiliar names in the presence of background babble. Five-month-old infants listened longer to their names when the target voice was 10 dB, but not 5 dB, more intense than the background. Nine-month-olds likewise failed to identify their names at a 5-dB signal-to-noise ratio, but 13-month-olds succeeded. Thus, by 5 months, infants possess some capacity to selectively attend to an interesting voice in the context of competing distractor voices. However, this ability is quite limited and develops further when infants near 1 year of age. 相似文献

Little is known about the acoustic cues infants might use to selectively attend to one talker in the presence of background noise. This study examined the role of talker familiarity as a possible cue. Infants either heard their own mothers (maternal-voice condition) or a different infant's mother (novel-voice condition) repeating isolated words while a female distracter voice spoke fluently in the background. Subsequently, infants heard passages produced by the target voice containing either the familiarized, target words or novel words. Infants in the maternal-voice condition listened significantly longer to the passages containing familiar words; infants in the novel-voice condition showed no preference. These results suggest that infants are able to separate the simultaneous speech of two women when one of the voices is highly familiar to them. However, infants seem to find separating the simultaneous speech of two unfamiliar women extremely difficult. 相似文献

Aggressive behavior in girls has received far less attention than similar problems in boys. This study examined self-representation, and others' representation of self, as predictors of relational aggression, overt aggression, and assaultive behavior in 32 girls and 52 boys, 10 to 17 years of age, referred for assessment due to significant aggressive and delinquent behavior problems. As predicted, negativity of self-representation predicted relational aggression in girls but not boys. Negativity of self-representation also predicted overt aggression and assaultive behavior in both girls and boys. Parental representations of self were not predictive in this sample; however, negativity of peer representations of self, was associated with increased relational aggression in girls and decreased relational aggression in boys. Negativity of peer representations of self also predicted overt aggression and assaultive behavior in both girls and boys. Results suggest that the evaluation of self-other representations may be valuable in the assessment of risk for gender specific patterns of aggression. 相似文献

This essay examines the increasing commodification of the body with respect to tissues, games, and embryos. Such commodifcation contributes to a diminishing sense of human personhood on an individual level, even as it erodes commitments to human flourishing at the societal level. After the case for social harm resulting from the increasing commodification of the body is made, the question becomes whether that harm is best remedied by following any of three approaches by which government traditionally seeks to promote the flourishing of its citizens. The author concludes that it is not, and that what is needed is a pragmatic and somewhat casuistic approach to the regulation of contested commodities--that which legal scholar Margaret Jane Radin calls "incomplete commodification." 相似文献

This paper offers a reading of Heidegger's 1931 lectures on Aristotle's Metaphysics, Theta 1-3 that relates that discussion to Heidegger's later work on The Question Concerning Technology and then, more briefly, to contemporary philosophical discussions of ecological issues. This reading is intended to open the possibility of using Heidegger's re-interpretation of Aristotle as a source within the Western European tradition for understanding our relationship to the natural world in a way that could provide the philosophical tools for addressing ecological problems more adequately and effectively. 相似文献

This study investigated variables related to how students choose to be remembered after high school (remembrance role). Over four hundred students in small, medium, and large high schools in a midwestern state provided information on demographics, parental characteristics, personality traits, participation in high school activities, and remembrance role. Discriminant analysis revealed that sports participation, social activity participation, high school academic rank, mother's education, and masculinity were the variables most strongly associated with the four remembrance roles: brilliant student, most popular, athletic star, and leader in activities. The findings are discussed, and suggestions for future research are presented. 相似文献

Three experiments illustrate that humor in advertisements prevents the development of negative brand associations due to resistance. Previous research on humor in advertising suggested that humor can counter negative responses during ad processing, but less is known about the effect of humor on the development of negative brand associations in memory. Brand associations are important because there is often a time delay between ad exposure and brand decisions. We separately manipulated two typical aspects of humor processing, that is, distraction and positive affect, and examined their effects on the development of respectively negative and positive brand associations. All experiments were conducted with university students as participants. The results showed that resistance causes negative brand associations (Experiments 1 and 2), and humor prevents the development of these negative brand associations more than nondistracting positive stimuli and neutral stimuli (Experiment 2 and 3). The prevention of negative brand associations was caused by the distractive properties of humor. Irrespective of resistance, the positive affect engendered by humor enhanced positive brand associations. Experiment 3 showed that distraction and positive affect in humor uniquely contribute to brand preference. Together, these results illustrate that the effect of humor on resistance follows a two-step process: humor forestalls the development of negative brand associations because of its distractive properties (cognitive mechanism), and engenders positive brand associations because of its positive emotional outcomes (affective mechanism). These effects of humor on brand associations jointly promote brand preference. 相似文献

Sexual assault is an insidious problem in the United States military. In 2005 the Department of Defense (DoD) created the Sexual Assault Prevention and Response Office, which centralizes responsibility for sexual assault training. However, this training initiative has undergone little evaluation by outside researchers. Addressing this need, we analyzed responses from over 24,000 active duty personnel who completed the 2010 DoD Workplace and Gender Relations Survey. We assessed whether sexual assault training exposure (None, Minimal, Partial, or Comprehensive) predicted accurate knowledge of sexual assault resources and protocols. Using a social-ecological framework, we investigated whether institutional and individual factors influenced Service members’ training exposure and judgment of training effectiveness. According to our results, exposure to comprehensive training predicted lower sexual assault incidence and superior knowledge. However, comprehensive training differed as a function of military branch, rank, gender, and sexual assault history. Judgments of training effectiveness also varied across these dimensions. Our results highlight the importance of considering context, gender, and victimization history when evaluating institutional efforts to end sexual violence. The DoD’s 2010 annual report on military sexual assault concluded that “most Active Duty members receive effective training on sexual assault” (p. 104). Our results cast doubt on that assertion. 相似文献
