Recognition memory and intelligence

The assumption that individual differences in recognition memory are associated with individual differences in intelligence was explored by administering intelligence tests and tests of immediate visual recognition memory to a sample of 52 5-year-old children expected to vary widely from one another in intelligence. Each child was given the Peabody Picture Vocabulary Test (Form L) and two tests of immediate recognition memory: one test for 27 abstract patterns and one test for 27 unfamiliar cartoon faces. The mean PPVT-IQ for the sample was in the average range at 98.1. Interindividual variability in IQ proved to be high as reflected in the group SD of 22.6, with scores ranging from 40 to 136. The recognition tasks proved to be of moderate difficulty. Individual differences in memory for patterns were highly related to memory for faces (r = .76), indicating that the overall recognition test was reliable. The most important result of the present study was the strong association between recognition memory performance and PPVT-IQ of .70. The relation between recognition memory and IQ could not be accounted for by the inclusion of a few very low IQ children, since the association remained high at .61 when children with IQs below 75 were omitted from analysis. In short, the present results indicate that immediate recognition memory is highly associated with intelligence.     

The Cutest Little Baby Face: A Hormonal Link to Sensitivity to Cuteness in Infant Faces

ABSTRACT— We used computer image manipulation to develop a test of perception of subtle gradations in cuteness between infant faces. We found that young women (19–26 years old) were more sensitive to differences in infant cuteness than were men (19–26 and 53–60 years old). Women aged 45 to 51 years performed at the level of the young women, whereas cuteness sensitivity in women aged 53 to 60 years was not different from that of men (19–26 and 53–60 years old). Because average age at menopause is 51 years in Britain, these findings suggest the possible involvement of reproductive hormones in cuteness sensitivity. Therefore, we compared cuteness discrimination in pre- and postmenopausal women matched for age and in women taking and not taking oral contraceptives (progestogen and estrogen). Premenopausal women and young women taking oral contraceptives (which raise hormone levels artificially) were more sensitive to variations of cuteness than their respective comparison groups. We suggest that cuteness sensitivity is modulated by female reproductive hormones.     

Unmarried, nonresident fathers' involvement with their infants: a risk and resilience perspective.

The authors used a subsample of fathers (n = 652) who participated during the 1-year follow-up of the Fragile Families and Child Wellbeing study to assess the influence of risk and resilience factors on unmarried, nonresident fathers' involvement with their infants. They examined the additive, multiplicative, and moderating models of risk and resilience in relation to paternal involvement. Fathers' relationship to the child's mother was conceptualized as a risk or resilience factor. Fathers in acquaintance relationships with the mother and fathers who scored higher on the additive risk index were less involved in child care. Fathers who scored higher on the additive resilience index were more involved in child care. There was a multiplicative effect of relationship status and the risk index on fathers' involvement. The findings point to the importance of programs that address risk and resilience conditions affecting nonresident fathers in interaction with the quality of relationships they have with their children's birth mother.     

Peritraumatic fear, helplessness and horror and peritraumatic dissociation: do physical and cognitive symptoms of panic mediate the relationship between the two?

The goal of this study was to examine whether panic mediates the relationship between fear, helplessness, and horror (PTSD criterion A2) and dissociation at the time of trauma. The study sample included 709 police officers and 317 peer-nominated civilians who had been exposed to a variety of critical incidents. Participants filled out measures of critical incident exposure, PTSD criterion A2, panic, and dissociation. Results indicate that together, physical and cognitive symptoms of panic completely mediate the relationship between criterion A2 and dissociation in civilians, and partially mediate that relationship in police. These results provide support for the idea that panic mediates the relationship between fear, helplessness, and horror (criterion A2) and dissociation at the time of trauma. The results also raise the possibility, however, that the mediational role of panic may be further moderated by additional variables.     

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.
