Measurement variability in infant and maternal behavioral assessment

Evaluations of methodological assessments sometimes show similar, sometimes different patterns of findings reflective of different approaches to the same problem. In this study, frequencies of behaviors of infants and mothers in two cultures based on continuous coding were compared with frequencies based on time-sampling, and resulting patterns of findings were evaluated. Time-sampling and continuous coding give different estimates of absolute frequency of typical infant and maternal behaviors between individuals and between cultural groups. However, time-sampling adequately preserves the relative ranking of infant and mother behaviors among individuals and between cultural groups. If research is concerned with the relative standing of individuals and/or groups on frequency of infant or maternal behavior, then (under specified circumstances) time-sampling and continuous coding yield comparable results.     

Infants' perception of directional alignment of texture elements on a spherical surface

By appropriately compressing texture elements on a circular surface, one can evoke the impression of being confronted with the depiction of a spherical object in the picture plane. According to Todd and Akerstrom (1987), the 3D perception of such an object can be eliminated if the optical elements are not sufficiently elongated or if they are not aligned with one another. In the current investigation, 4‐month‐old infants were tested for their ability to react to a disruption of the directional alignment variable. They were habituated to either a spherical surface or a surface the spatial layout of which was destroyed by reorienting the texture elements, and were afterwards tested with a further ellipsoid object and with a further flat surface. Data analysis revealed that the female infants, but not the male participants, preferred the novel posthabituation display, that is, the test stimulus which included a change in the orientational alignment of texture elements. These findings are discussed within the context of development of sensitivity to pictorial depth cues. It is possible that infants as young as 4 months of age respond to manipulations of the directional alignment factor per se, while older infants are capable of using this factor as a cue for 3D object shape.

Who's controlling whom? Infant contributions to maternal play behavior

Because the way mothers play with their children may have significant impacts on children's social, cognitive, and linguistic development, researchers have become interested in potential predictors of maternal play. In the present study, 40 mother–infant dyads were followed from child age 5–20 months. Five‐month habituation rate and 13 and 20 month temperamental difficulty were found to be predictive of maternal play quality at 20 months. The most parsimonious theoretical model was one in which habituation was mediated by temperamental difficulty in predicting mother play. Consistent with prior speculation in the literature, these data support the possibility that mothers adjust some aspects of their play behaviors to fit their children's cognitive and temperamental capabilities.

Perception of correlated attributes involving African–American and white females' faces by 10‐month‐old infants

Thirty‐two 10‐month‐olds were habituated to stimuli containing an African–American female face or a white female face paired with a specific object. Test stimuli maintained or violated habituation stimuli pairings (i.e. categories). Results add to an emerging literature showing that 10‐month‐olds perceive categories of social information based on detection of correlated attributes. Copyright © 2003 John Wiley & Sons, Ltd.     

Behavioral and environmental correlates of infant abuse in group- living pigtail macaques

The present study investigated the context of occurrence of infant abuse and the behavior of abusive mothers and their infants in pigtail macaques (Macaca nemestrina). Subjects were 8 abusive mothers with their infants and 8 control mother-infant pairs living in 3 captive social groups. The most common forms of abuse were infant crushing and dragging and the most common context of occurrence was social stress. Severe and mild abuse differed in the frequency but not in the type of abuse patterns. Abusive mothers had controlling parenting styles relative to nonabusive mothers, and abused infants played at a later age and less frequently than controls. This study replicates previous findings on the parenting styles of abusive macaque mothers and provides new evidence on the context of occurrence of abuse and its consequences for infant health and social development.

Intergenerational Transmission of Trauma-Related Distress: Maternal Betrayal Trauma,Parenting Attitudes,and Behaviors

The purpose of this study was to elucidate mechanisms involved in the intergenerational transmission of trauma-related distress. This study investigated whether betrayal trauma (BT; abuse by a person close to the victim) and specific parenting attitudes and behaviors among mothers with child abuse histories predicted internalizing and externalizing symptoms in their children. Mothers and children (ages 7–11) were recruited for a project on parenting and stress (N = 72). Maternal betrayal trauma predicted both internalizing (β = 0.33, p < .01) and externalizing symptoms (β = 0.25, p < .05) even when controlling for mothers’ trauma-related symptoms. Negative attitudes toward limit setting predicted externalizing symptoms (β = ?0.33, p < .05). Poorer communication (β = ?0.39, p < .05) but higher parenting satisfaction (β = 0.38, p < .01) predicted internalizing symptoms. These findings demonstrate the importance of assessing maternal trauma and parenting characteristics as part of interventions with symptomatic children.     

The ideological manipulation of Hebrew literature in English translation in the 1970s and 1980s

In the past two decades, the field of translation studies has increasingly focused on the role of ideology in literary translation and cross-cultural transfer. This paper presents findings from the close textual comparison of original works of Hebrew literature and their English translations published in the United States during the 1970s and 1980s. I specify translation strategies that have had ideological effects on the source texts, and demonstrate how historically or ethically charged subject matter was manipulated so as to subdue “problematic” aspects of the text for the (largely Jewish) target audience. The two major categories of manipulations had to do with the moral dimension of the portrayal of Israel and Israeli society, particularly in subject matter related to the Israeli–Palestinian conflict; and with the relationship between Israel and other nations, and between Israel and Diaspora Jews. As stressed by recent sociological studies of translation, the translations can be seen both as reflective of contemporary socio-political trends of thought, and as practices playing an unseen role in strengthening these trends.     

Individual,relationship, and context factors associated with parent support and pressure in organized youth sport

ObjectivesWe examined the association of multiple process, person, and context factors (Bronfenbrenner, 2005) with parents’ involvement (support and pressure) in sport. Specifically, we examined (a) the concordance among self, partner, and child reports of fathers and mothers for key study variables, and (b) prediction of parent support and pressure in youth sport by warmth and conflict in the parent–child relationship, parent positive and negative affect, and mastery and ego dimensions of the coach-created motivational climate.DesignCross-sectional survey.MethodSelf-reports of study variables were collected from athletes (ages 11–13 years) and parents from participating families (final N = 201). Multitrait-multimethod analysis was used to address the first study aim and multivariate multiple regression analysis for the second aim.ResultsValues for concordance among reporters were largely significant and in hypothesized directions, yet were of modest magnitude and suggested low reporter agreement (Cohen's κ range = −.07–.35). Multivariate relationships were significant and were of low to moderate magnitude (R_d range = .04–.22). Canonical loadings showed that warmth, positive affect, and mastery climate positively associate with support, whereas conflict, negative affect, and ego climate positively associate with pressure from fathers and mothers. Conflict and positive affect positively associated with support and pressure in some functions, suggesting complexity in interpretations of parent involvement.ConclusionFindings support the adaptive role of parent-child warmth, positive parent affect, and coach-created mastery motivational climate in youth sport; however, low concordance of reporter perceptions must be considered when pursuing family-related questions in sport.
