It has been established through several decades of research that children's home environments significantly influence their development. Many researchers have also been interested in expanding research beyond indirect measures of the home environment, such as socioeconomic status, to help understand the nature of specific environmental mechanisms which influence early behavior and cognitive development. The Home Observation for Measurement of the Environment (HOME) Inventory was developed to meet these needs. Specifically, HOME measures the quality of stimulation in a child's early family environment. Almost all studies of the approach's reliability and validity have been conducted with US samples. HOME is, however, being used in other countries. The authors report their findings from a study of whether the psychometric properties of HOME based upon US samples parallel those found in Costa Rica, and whether HOME discriminates between Costa Rican environments with different associations to child health and development. Focus centers upon the infant/toddler version of the HOME Inventory. HOME data for 183 healthy Costa Rican infants were compared to the original HOME standardization sample from Little Rock, Arkansas. The study found the HOME Inventory to be helpful in identifying children at risk for delayed development in this Latin American sample. Lower HOME scores related to a shorter duration of breastfeeding and differentiated children with iron deficiency anemia in infancy, a condition associated with long-lasting developmental disadvantage.  相似文献

Gender role perceptions of five objects—Ideal Woman, Ideal Man, Most Women, Most Men and Self—were elicited from 3300 university students, 81% of whom were Caucasian, with 7% Hispanic, 6% African-American, and 4% Asian. Profiles of student responses for the five objects provided a comprehensive updating of 1970s research on student gender roles. Women (N= 1842) and men (N= 1148) students generally preferred an androgynous Ideal Woman. Women also preferred an androgynous Ideal Man, but men preferred a masculine sex-typed Ideal Man. Women and men's perceptions of Most Women and Men continued to be sex-typed. Men's self perceptions were androgynous, while women saw themselves as feminine sex-typed. Findings suggest that little change in students' gender role perceptions has occurred in the past 15 years.  相似文献

RESOLUTION OF LEXICAL AMBIGUITY BY EMOTIONAL STATE   总被引:2,自引:0,他引:2  
Abstract— The role of emotion in the resolution of lexical ambiguity was investigated. Happy and sad subjects listened to a list of words that included homophones that had happy and neutral meanings (eg., presents-presence ) and homophones that had sad and neutral meanings (eg., mourning-morning ). Words were presented every 3 s, and subjects wrote down the words, as they heard them (Meaning could be identified by spelling in all cases). An interaction between emotional state and homophone category was observed. Sad subjects were more likely to write down sad meanings than were happy subjects. Results are discussed with reference to the literatures on both emotion and lexical access.  相似文献
