Videotaping effects on the behaviors of low income mothers and their infants during floor-play interactions

Interaction behaviors and language measures of low income mothers and their 12-month-old infants were compared for floor-play situations in which the mother was aware and unaware of being videotaped. When the mothers were aware of being videotaped, they were more proximal to their infants, offered and demonstrated toys more frequently, engaged in more frequent interaction games, vocalized more frequently, emitted a greater number of words as well as declarative and imperative utterances, and their infants engaged in more constructive play. Combining the analysis of variance and correlational analyses results suggested that the verbal behaviors of mothers were inflated and their non-verbal behaviors were distorted when they were aware of being videotaped. The implications of these data for the use of videotaping as an assessment and intervention tool are discussed.     

Early mother-infant interaction during breast- and bottle-feeding

Thirty-two primiparous mothers with their neonates, 20 breast-fed and 12 bottle-fed, were videotaped during feeding longitudinally (at 3, 10 days, 1 and 3 months) in order to investigate whether patterns of mother-infant interaction observed during breast- and bottle-feeding differ also for behavior not directly related to sucking. Infant state, sucking behavior, mother behavior and mother-infant interaction were analyzed by both sequential and non sequential analysis. Results suggest that the method of feedings affects mother-infant interaction observed during and just after feeding also for some behavior not directly related to sucking. The percentage of mutual touch, tactile stimulation and mother's gaze to infant was significantly more elevated during breast-feeding. Independently of the feeding mode, significant sequential dependencies between infant state of alertness and auditory stimulation, and auditory stimulation and mutual gaze were found.     

Attitudinal and demographic predictors of breast-feeding and bottle-feeding behavior by mothers of six-week-old infants

The demographic and attitudinal characteristics of 42 bottle feeding and 41 breast feeding mothers of 6 week old infants were compared. The women were patients of private physicians in Nashville, Tennessee. Data was obtained from self-administered questionnaires distributed through the physicians' offices. The women were primarily middle class whites and one-half of the women were multiparous and one-half were primiparous. On the basis of the information obtained in the questionnaires respondents were given scores on 13 demographic and family history characteristics and on 16 attitudinal scales which measured the mothers' preceptions of family life, child rearing, and breast feeding. Discriminant function analysis was used to assess the differences in the mean scores on each of the 29 variables for the 2 groups of mothers. Major findings were: 1) breast feeding mothers were significantly more educated and had significantly more breast feeding friends than bottle feeding mothers; 2) breast feeding mothers viewed their husbands as significantly more supportive of their feeding method than bottle feeding mothers; 3) bottle feeding mothers perceived more conflict in their marriages than breast feeding mothers; 4) bottle feeding mothers tended to favor accelerating the development of their infants more than the other mothers; and 5) breast feeding mothers had more positive attitudes toward breast beeding than bottle feeding mothers. Most of the women in both groups decided on their method of feeding prior to delivery, and complications during and following delivery did not alter their plans significantly. The 2 groups did not differ significantly in the degree to which they: 1) fostered dependency in their infants; 2) felt possessive toward their infants; 3) rejected the housewife role; and 4) were secluded at home.     

Resource-dependent effects during sex categorization

The limited capacity of face perception resources in the left cerebral hemisphere was examined using a sex categorization task. One study tested the hypothesis that sex categorization is impeded whenever feature extraction resources in the left hemisphere are simultaneously being utilized by another task. This hypothesis was tested by presenting prime faces for either 32 ms or 320 ms to either the left or right visual-field just before centrally presented target faces were categorized by sex. Results showed that sex categorization was slower after prime faces were presented for 32 ms in the right visual-field compared to the left visual-field. This difference was not found after the 320 ms prime length. The results are interpreted in the context of a neurocognitive model of social perception and suggest that efficient sex categorization depends, in part, on the availability of facial feature extraction resources in the left hemisphere.     

Neonatal amphetamine exposure and hippocampus-mediated behaviors

Previous studies linking amphetamine use during pregnancy to changes in the behavioral development of affected infants have greatly increased society’s level of concern regarding amphetamine use by women of reproductive age. The aim of this study was to investigate whether exposure to d-amphetamine sulfate during the brain growth spurt, the most dynamic period of brain development, alters hippocampus-mediated behaviors during both pre-adolescence and young adulthood. Sprague–Dawley rat pups were intragastrically administered a milk formula containing 0, 5, 15 or 25 mg/kg/day of amphetamine from postnatal day (PD) 4–9. Following weaning, the effects of neonatal amphetamine exposure on hippocampus-mediated behaviors were assessed using the open-field, the water maze, and the conditioned taste aversion behavioral tasks. Results from these behavioral tests revealed that while amphetamine exposure during the brain growth spurt alters behaviors in open-field testing, it does not interfere with performance in either the water maze or the conditioned taste aversion paradigm. These results offer speculation that the effects of neonatal amphetamine exposure on hippocampus-mediated behaviors may be related to interactions between the “temporal” (time of drug exposure) and “regional” (different regions of the hippocampus) vulnerability issues.     

Differences in practices of body stimulation during the first 3 months: Ethnotheories and behaviors of Italian mothers and West African immigrant mothers

This study investigated cultural differences, continuity and change of practices concerning body stimulation in a context of immigration. Parenting behaviors during the interaction with infants at 4, 8 and 12 weeks, and parenting ethnotheories at 12 weeks of first-generation West African immigrant mothers in Italy and autochthonous Italian mothers were compared. A qualitative inspection of ethnotheories using a thematic approach was included. As expected, results showed that immigrant mothers placed more emphasis on motor stimulation and showed longer durations of rhythmic motor and rhythmic tactile behaviors than Italian mothers; the latter placed more emphasis on tactile stimulation than immigrant mothers. The practice of motor stimulation in immigrant mothers was also adapted to values of the new context of life, becoming a positive interaction game with a mutual exchange of positive emotions. Findings express the complexity of a multidimensional process of acculturation.     

Altering withdrawn and intrusive interaction behaviors of depressed mothers

Interaction coaching was given to 44 depressed mothers who had either a withdrawn or intrusive interaction style with their infants. The intrusive and withdrawn mothers were given instructions either to imitate their infants' behavior or to keep their infants' attention. The results suggested that the specific type of interaction coaching for the specific type of depressed mother (imitation for the intrusive mothers and attention-getting for the withdrawn mothers) significantly improved their interaction behaviors with their infants.     

Discipline behaviors of Chinese American and European American mothers

In any society, parenting beliefs are a reflection of that society's cultural values and traditions (J. U. Ogbu, 1981). Verbosity, a parenting behavior considered dysfunctional in European American culture, may not be problematic in Chinese culture. The authors recruited 31 Chinese American and 30 European American mothers and used questionnaires to measure parenting behaviors and child behavior problems. The Chinese American mothers also completed a questionnaire assessing their acculturation level. The Chinese American mothers had higher levels of verbosity than did the European American mothers; however, there were no differences between the groups in child behavior problems. The results also revealed higher levels of laxness in the Chinese American mothers compared to the European American mothers. Acculturation level did not predict verbosity or laxness levels. Results suggest that the effectiveness of a parenting style should be defined relative to cultural context.     

Extinction effects during the assessment of multiple problem behaviors

Extinction effects were evaluated in a multiple baseline across behaviors design with 2 boys after just one of several target problem behaviors was observed during a functional analysis. Other target behaviors emerged as extinction was introduced sequentially across all problem behaviors. Results demonstrated an efficient strategy for simultaneously assessing multiple problem behaviors maintained by the same consequence.     

Preconscious effects of temporary goals on attention

Two experiments examined whether accessible goals preconsciously direct selective attention. Goal activation was manipulated by one's goal pursuit being either undermined or affirmed (resulting in an experienced state of either incompleteness or completeness). Attention responses were assessed through a Stroop-like task (Experiment 1) and a response-time task in which participants indicated a stimulus' direction of motion (Experiment 2). Results showed that when goals were accessible, attention was drawn toward goal-relevant items—even when these items were to be ignored and when responses occurred too fast for conscious control. Accessible goals directed implicit cognition (i.e., attention toward stimuli associated with the goal), despite the fact that these goals were not chronically held, but manipulated in the lab.     

Preschool children with externalizing behaviors: Experience of fathers and mothers

Childhood behavior disorders are related to family stress and maladjustment. Little is known, however, about the adjustment of families with preschool-aged children at risk for subsequent behavior disorders. Moreover, fathers' perceptions of child problem behavior and their reactions to it generally have been neglected. Subjects were mothers and fathers of 52 preschool-aged children assigned to one of three groups: control, moderate externalizing, and high externalizing. Higher child externalizing behavior was associated with greater negative family impact, lowered parenting sense of efficacy, and child-rearing practices that were more authoritarian and less authoritative. Mothers and fathers did not differ in actual perceived level of child behavior problems, although both believed that mothers saw more problems. Child Group × Parent interactions indicated that mothers experienced increased stress and a need for help with moderate as well as high child externalizing behaviors, whereas fathers were not elevated on these measures unless the child's externalizing behaviors were high. Implications of these findings for early family intervention are considered.This study is part of the Preschool Project, conducted at UCLA's Fernald Child Study Center, Co-PIs Bruce L. Baker and Barbara Henker. We appreciate the involvement of Barbara Henker, Erin Gallagher, Laurel Smith, and Terry Webster.

Infants’ expressive behaviors to mothers and unfamiliar partners during face-to-face interactions from 4 to 10 months

Changes in the organization of infant looking, facial expressions, and vocalizations were examined over age (4, 7, and 10 months) and with different social partners. Although infants at all ages accompanied smiling with looking at both mothers and unfamiliar partners, 7- and 10-month infants accompanied vocalization with looking only when they were with mothers. Seven- and 10-month-olds vocalized with unfamiliar partners only when they were smiling at the same time. When mothers stopped talking, infants reduced smiling significantly at all ages, yet vocalized more at 10 months. In the second half of the first year, there are fundamental changes in the coordination of infant expressive behaviors that reveal a keen attunement to variations in maternal behavior and the familiarity of social partners.     

An evolutionary psychology perspective on sex differences in exercise behaviors and motivations

Researchers have found that men and women pursue sex-appropriate strategies to attract mates. On the basis of intrasexual competition, men should be more likely to enact behaviors to look larger, whereas women should be more likely to enact behaviors to look smaller. The types of exercises that each performs should reflect this expectation. The present study replicates and extends work by L. Mealey (1997) on sex differences in exercise behavior. In the present study, male participants focused their energy on gaining muscle mass and enhancing their upper body definition, whereas female participants focused their energy on losing weight with emphasis on their lower body. Both sexes reported efforts to improve their abdominal region. It appears that men and women adopt sex-appropriate exercise behavior as a method of self-enhancement for intrasexual competition.     

Interactive effects of social context and sex role identity on female self-disclosure during the acquaintance process

Female subjects who differed in masculinity and in femininity self-disclosed to a same-sex confederate in contexts that made either social/expressive motives or instrumental motives particularly salient. The confederate spoke first on each of four disclosure topics, presenting either intimate or nonintimate information in her disclosures. The results were consistent with our primary assertion that measures of sex role identity would accurately forecast contextual variations in female self-disclosure. Specifically, femininity tended to promote self-disclosure in social/expressive contexts while clearly inhibiting such exchanges in the instrumental context. Supplementary data revealed that the tendency of highly feminine participants to close up in the instrumental context stemmed not from problems in their contemporaneous interpersonal relationships with their partners, but rather from a concern that disclosing too much might adversely affect their partners' evaluation of their competencies. Although masculinity did not exert direct effects of female self-disclosure within any particular context, it did have an influence, for subjects high in femininity were highly self-revealing across contexts if they were also high in masculinity (i.e., androgynous).This research was supported by National Institute of Mental health Grant MH 43726-01 to David R.

Adolescent triangulation into interparental conflict: Role of cognitive appraisals and birth-order

ABSTRACT

Triangulation of adolescents into interparental conflict has since long been recognized as a risk factor for adolescents’ psychological adjustment. However, there is a scarcity in research focusing on exploring the variables that make adolescents more vulnerable to get triangulated. This study used a cross-section research design to examine the relationship between interparental conflict and adolescent triangulation into that conflict in an under-researched population of Pakistani school going adolescents (N = 521), with an age range of 13-19 years (M = 15.25; SD = 1.46); while exploring the role of adolescent’s cognitive appraisals (threat and self-blame) and birth-order. The results indicated that interparental conflict, appraisal of threat and appraisal of self-blame are significant predictors of adolescent triangulation. Moreover, this study also revealed the moderating role of adolescent birth order in the relationship between interparental conflict and triangulation, as well as between appraisal of self-blame and triangulation; indicating that the ‘only’ child in the family was at the highest risk of being triangulated into their parents’ arguments, while the youngest child was least likely to get involved.     

Attachment in preterm infants and their mothers: Neonatal risk status and maternal representations

High‐risk neonatal status, indexed by an intracranial hemorrhage (ICH), and maternal representations of past and present attachment relationships were examined as predictors of infant attachment in a sample of preterm infants. Participants included 50 19‐month‐old infants and their middle‐class, predominantly African American mothers. A maternal‐report questionnaire and a structured interview were used to assess past relationship history with mother and current relationship with infant, respectively. The Strange Situation Paradigm was used to assess attachment security. Multiple logistic regression analyses suggested that maternal representation of the infant—but not ICH or maternal childhood history—significantly predicted infant attachment security. ICH and maternal history of childhood rejection were predictive of disorganized infant attachment. The findings are consistent with previous data that suggest that maternal factors are more important than infant factors in determining infant attachment security. These data also suggest that neurological deficits may contribute to disorganized infant attachment. © 2000 Michigan Association for Infant Mental Health.     

Women’s oral sex behaviors and risk of partner infidelity

Pham and Shackelford (2013a) documented that men at greater risk of their partner’s infidelity reported greater interest in and spent more time performing oral sex on their partner. The current study is an extension of their study to a female sample. We recruited 200 women to investigate whether women’s oral sex behaviors are related to the risk of their partner’s infidelity. The results indicate that women at greater risk of partner infidelity did not report more interest in, or spend more time performing, oral sex on their partner. Additionally, the relationships between partner infidelity risk and interest in, and time spent, performing oral sex were greater for men than women. We discuss limitations of this research and discuss explanations for the results.
