Infants’ understanding of auditory events

Infants’ reaching‐in‐the‐dark was studied in a sample of normal 7.5–11‐month‐olds to determine whether infants can use sound cues to localize and recognize the action and objects of complex events. Infants were shown an event in which a moving, sounding object rotated clockwise through the infant's reaching space in the light and dark. Infrared recorded videotapes were later coded for reaching behaviour. Results showed that infants were able to localize the object on most trials in the dark but were slower and less efficient than in the light. Infants grasped the object at first contact and contacted the object near its salient feature in the dark, suggesting recognition of the object. Further, contact time was 1.7 s less when infants grasped the object at first contact in the dark (recognition) than when they touched the object, suggesting that recognition of the object improves reaching efficiency. There were no age and gender differences. In sum, the results support the use of the reaching‐in‐the‐dark method to demonstrate auditory localization of moving sounds and to reveal infants capacity to use represented information to guide subsequent action.

Phonological short‐term memory and vocabulary development: further evidence on the nature of the relationship

The nature and generality of the developmental association between phonological short‐term memory and vocabulary knowledge was explored in two studies. Study 1 investigated whether the link between vocabulary and verbal memory arises from the requirement to articulate memory items at recall or from earlier processes involved in the encoding and storage of the verbal material. Four‐year‐old children were tested on immediate memory measures which required either spoken recall (nonword repetition and digit span) or recognition of a sequence of nonwords. The phonological memory–vocabulary association was found to be as strong for the serial recognition as recall‐based measures, favouring the view that it is phonological short‐term memory capacity rather than speech output skills which constrain word learning. In Study 2, the association between phonological memory skills and vocabulary knowledge was found to be strong in teenaged as well as younger children, indicating that phonological memory constraints on word learning remain significant throughout childhood.

Maternal correlates of infant temperament ratings and of infant-mother attachment: A longitudinal study

This study examined longitudinally correlates of mothers' ratings of their infant's temperament and of the infant-mother attachment relationship. Measures included Carey's Revised Infant Temperament Questionnaire, child-rearing attitudes, psychophysiological responses to an unfamiliar infant's crying pre- and postdelivery, psychophysiological responses to the mother's own infant's crying, and assessments of infant-mother attachment. The results indicated that maternal ratings of infant temperament at 4 months were significantly related not only to concurrent cry responsiveness but also to cry responsiveness and child-rearing attitudes predelivery, as well as to the quality of attachment at 1 year. It is suggested that a differential response pattern of mothers of “easy” and of “difficult” infants, which affects the developing infant-mother bond, may in part originate in maternal dispositions existing prior to parenthood.     

Girls Not Boys Show Gender-Connotation Encoding from Print

The present study examines gender differences in children's encoding of gender-connotation from words. The release from proactive interference method was used to measure gender-connotation encoding. Forty-eight third-grade children attending a public elementary school serving a predominantly White middle-socioeconomic-status community participated and were presented with stimulus words in print. The design of the study can be characterized as a two (gender) by two (condition: control vs. experimental) by four (trials) factorial. Results revealed reliable proactive interference buildup and release for gender-connotation for girls, but not for boys. This new finding, taken together with extant research, demonstrates that while both boys and girls have the ability to encode gender-connotation from aurally presented words, the spontaneous activation of gender-connotation attributes with print is not guaranteed for boys.

Brief Report: Power and Attitudes in Relationships (PAIR) Among a Sample of Low-Income,African-American Women: Implications for HIV/AIDS Prevention

This study describes a scale that was designed to measure low-income urban, heterosexual women's perception of Power and Attitudes in Relationships (PAIR). Although frequently mentioned in the literature as an important aspect of women's risk for HIV, there are few described scales which measure such attitudes among this population. PAIR was based in part on Connell's (1987) Theory of gender and power. PAIR was found to be reliable (alpha = 0.79) among a Baltimore cross-sectional sample of inner-city women (n = 417), half of whom were HIV-negative and half were HIV-positive. Our findings suggest that PAIR is reliable among both HIV-infected and HIV-uninfected inner-city women. The scale can be a useful tool in understanding the interpersonal context of women's risk of HIV.
