An adaptive up-down tracking procedure was used in combination with a visually reinforced head turn response to examine auditory sensitivity for 500, 2000, and 8000-Hz tone bursts in infants 6 to 18 months of age. Six- and 10-month-old infants were tested with headphone presentation of stimuli, while 10-, 14, and 18-month-olds were tested in sound field. Infant threshold estimates for both headphone and sound field were within 15 dB of adult comparisons for all frequencies and age groups. Six-month-olds were significantly less sensitive to the 8000-Hz tone than to either of the lower frequency stimuli, but older infants demonstrated approximately equal sensitivity for all three frequencies tested. 相似文献

Comments on the Heller et al. telephone intervention with isolated elderly women are presented. The importance of addressing contextual factors involved in assessments of social support in community samples is discussed. Comparisons are drawn between the assessment of social support among an elderly sample and an assessment of social support among a sample of chronic illness patients. Three key issues are discussed: (a) Is a little support better than no support and is a little all we really need? (b) Is family support more important than friend support, at least to this population? (c) Can long-term relationships be replaced? 相似文献

This study examined the effects of personal religious orientation, religious denomination, and gender on attitudes toward women and their work roles using a sample of 263 single undergraduate university students. Subjects with a high intrinsic religious orientation put significantly more emphasis on family than career in their anticipated general lifestyle relative to those with a low intrinsic religious orientation. Subjects with a high intrinsic religious orientation were also more likely to anticipate the female spouse spending less time in a profession during the children's early years. Males showed more traditional attitudes toward women than females, but there were no gender effects on measures of preferred general lifestyle, preferred child-care distribution, or preferred career involvement for the wife. Subjects belonging to mainline and conservative denomination did not differ significantly in their attitudes toward women or their work roles. 相似文献
