Infant recognition memory and later intelligence

The present study asked if tests of visual recognition memory during infancy based on differential fixation to novel and previously seen targets are valid predictors of later intelligence for children scoring in the normal to superior range of intelligence. Statistically significant and moderate correlations of .37 and .57 were obtained between infant recognition memory scores obtained at four to seven months and later vocabulary tests of intelligence, for 54 children tested at four and for 39 children seen at seven years, respectively. The coefficients did not vary by sex, and were independent of differences in socio-economic status.     

Religiosity/spirituality and health. A critical review of the evidence for biological pathways

The authors review evidence regarding the biological processes that may link religiosity/spirituality to health. A growing body of observational evidence supports the hypothesis that links religiosity/spirituality to physiological processes. Although much of the earliest evidence came from cross-sectional studies with questionable generalizability and potential confounding, more recent research, with more representative samples and multivariate analysis, provides stronger evidence linking Judeo-Christian religious practices to blood pressure and immune function. The strongest evidence comes from randomized interventional trials reporting the beneficial physiological impact of meditation (primarily transcendental meditation). Overall, available evidence is generally consistent with the hypothesis that religiosity/spirituality is linked to health-related physiological processes--including cardiovascular, neuroendocrine, and immune function--althogh more solid evidence is needed.     

Social Network Characteristics,Social Support,and Cigarette Smoking among Asian/Pacific Islander Young Adults

Cigarette smoking may be one of the factors contributing to the high levels of cancer‐related mortality experienced by certain Asian/Pacific Islander (A/PI) subgroups (e.g., Native Hawaiian). Given the collectivist cultural orientation attributed to A/PI groups, social strategies are recommended for substance abuse or smoking cessation treatment among A/PI. However, research examining how social network characteristics and social support relate to smoking across A/PI subgroups has been lacking. This study investigated the associations between social network characteristics (e.g., size, composition), perceived social support, and recent cigarette use across Native Hawaiian, Filipino, and East Asian (e.g., Japanese, Chinese) young adults (18–35 year old). Cross‐sectional, self‐report data were collected from N = 435 participants (M age = 25.6, SD = 8.3; 61% women). Ethnic differences were found in a number of pathways linking social network characteristics, perceived social support, and cigarette smoking. Larger network size was strongly associated with higher perceived social support and lower recent cigarette smoking among Native Hawaiians but not Filipinos or East Asians. Higher perceived social support was associated with lower recent smoking among East Asians and Filipinos but not Native Hawaiians. Implications are discussed with regard to smoking prevention and cessation among A/PI.     

Synchrony,complexity and directiveness in mothers’ interactions with infants pre- and post-cochlear implantation

This study investigated effects of profound hearing loss on mother–infant interactions before and after cochlear implantation with a focus on maternal synchrony, complexity, and directiveness. Participants included two groups of mother–infant dyads: 9 dyads of mothers and infants with normal hearing; and 9 dyads of hearing mothers and infants with profound hearing loss. Dyads were observed at two time points: Time 1, scheduled to occur before cochlear implantation for infants with profound hearing loss (mean age = 13.6 months); and Time 2 (mean age = 23.3 months), scheduled to occur approximately six months after cochlear implantation. Hearing infants were age-matched to infants with hearing loss at both time points. Dependent variables included the proportion of maternal utterances that overlapped infant vocalizations, maternal mean length of utterance, infant word use, and combined maternal directives and prohibitions. Results showed mothers’ utterances overlapped the vocalizations of infants with hearing loss more often before cochlear implantation than after, mothers used less complex utterances with infants with cochlear implants compared to hearing peers (Time 2), and mothers of infants with profound hearing loss used frequent directives and prohibitions both before and after cochlear implantation. Together, mothers and infants adapted relatively quickly to infants’ access to cochlear implants, showing improved interactional synchrony, increased infant word use, and levels of maternal language complexity compatible with infants’ word use, all within seven months of cochlear implant activation.     

Neurodevelopmental outcomes of Ugandan infants with HIV infection: an application of growth curve analysis.

Neurodevelopmental outcomes of human immunodeficiency virus Type 1 (HIV-1)-infected infants of non-drug-using mothers were assessed in a controlled, prospective study from birth to 24 months with 3 groups: 61 infants of HIV-infected mothers, 234 uninfected infants of HIV-infected mothers (seroreverters), and 115 uninfected infants of uninfected mothers. Compared with seroreverters and uninfected infants, HIV-infected infants demonstrated lower mental and motor development on the Bayley Scales and greater deceleration in their rate of motor development. HIV-infected infants with abnormal neurologic exams had lower motor and mental test scores and lower rates of motor Bayley Scales scores than their HIV-infected counterparts with normal neurologic exams. Contrary to prediction, no group differences in mean performance or growth rates were found on visual information processing on the Fagan Test of Infant Intelligence.     

WOMEN'S PSYCHOLOGICAL ADJUSTMENT FOLLOWING EMERGENCY CESAREAN VERSUS VAGINAL DELIVERY

The present study was designed to investigate possible differences in psychological adjustment and satisfaction between women delivering vaginally and those delivering by emergency cesarean section. Women's satisfaction with the birth experience was distinguished from postpartum psychological adjustment, as measured by depression, anxiety, and confidence in mothering ability. Twenty-two women who delivered vaginally and twenty-two women who delivered by emergency cesarean section were selected according to stringent criteria, to control for factors known to be associated with positive cesarean outcomes. Significant differences were found in level of satisfaction, with cesarean mothers reporting less satisfaction with the delivery than vaginal mothers. However, no differences were found between the groups on the three measures of psychological adjustment. Under optimal conditions, cesarean deliveries are not associated with adverse early postpartum psychological adjustment.
