Posture Development in Infants at Heightened versus Low Risk for Autism Spectrum Disorders

Evidence suggests that children and adults diagnosed with autism spectrum disorders (ASD) exhibit difficulties with postural control. Retrospective video studies of infants later diagnosed with ASD indicate that infants who eventually receive an ASD diagnosis exhibit delays in postural development. This study investigates early posture development prospectively and longitudinally in 22 infants at heightened biological risk for ASD (HR) and 18 infants with no such risk (Low Risk; LR). Four HR infants received an autism diagnosis (AD infants) at 36 months. Infants were videotaped at home at 6, 9, 12, and 14 months during everyday activities and play. All infant postures were coded and classified as to whether or not they were infant‐initiated. Relative to LR infants, HR infants were slower to develop skill in sitting and standing postures. AD infants exhibited substantial delays in the emergence of more advanced postures and initiated fewer posture changes. Because posture advances create opportunities for infants to interact with objects and people in new and progressively more sophisticated ways, postural delays may have cascading effects on opportunities for infant exploration and learning. These effects may be greater for infants with ASD, for whom posture delays are more significant.     

Maternal Functioning, Time, and Money: The World of Work and Welfare

Numerous studies have assessed families' employment and financial stability following welfare reform. Yet little research has addressed whether welfare and work transitions are linked with other changes in family functioning. Using a representative sample of approximately 2,000 low-income urban families from the Three-City Study, analyses assessed whether mothers' welfare and employment experiences over a two-year period following welfare reform were related to changes in family well-being. Lagged regression models controlling for family characteristics and earlier levels of functioning found that moving into employment and stable employment (of 30 hours or more per week) were linked to substantial increases in income and improvements in mothers' psychological well-being. Movements into employment also were associated with declines in financial strain and food insecurity. Sustained or initiated welfare receipt was related to relative declines in income, physical health, and psychological well-being, but also to improved access to medical care. In contrast, mothers' welfare and work experiences showed very limited relations to changes in the quality of parenting or of children's home environments. These patterns were similar for families with young children and those with adolescent children. Results suggest that parenting behaviors are more resistant to change than are maternal emotional and economic functioning.     

Social mobility in Scotland since the middle of the twentieth century

Extensive mobility between class of origin and class of destination has been a characteristic feature of societies in Europe and North America since the middle of the twentieth century. Most mobility has been upward, and most of that has been explicable by occupational change – by the rise in the proportion of the labour force which works in service‐class jobs and the decline in the proportion in manual jobs. This pattern may now be changing, because parents of younger cohorts (people born since the 1960s) have themselves benefited from upward mobility and so there is less scope for further upward movement by their offspring. The paper uses a large new data source for Scotland to investigate these topics. It finds that there is still a great deal of mobility, and that, although upward mobility still predominates, its amount is lower in younger cohorts than in older. Nevertheless, relative mobility has not changed as upward mobility has declined, just as in earlier studies it was found not to have changed as upward mobility rose. These patterns are similar for men and women.     

Effects of alcohol on the nonverbal communication of anxiety: The impact of beliefs on nonverbal behavior

Three male and three female raters were shown videotapes of 29 male subjects who were speaking to a silent female confederate. Raters were asked to make 10 judgments about the subjects' behavior. The subjects had been assigned to one of two expectancy conditions in which they were led to believe the drink they consumed prior to meeting the confederate contained alcohol and tonic or tonic only. Actually, half of the subjects in each expectancy condition received alcohol and half received tonic only. Judgments of the female raters viewing the videotapes were congruent with physiological measures of the subjects' anxiety. Those subjects who believed they received alcohol were perceived by female raters as more relaxed, less anxious, less inhibited, and more dominant than subjects who believed they received tonic. The actual content of the drink had no significant effects on the raters' judgements of the subjects' behavior. Male raters were unable to discriminate among the experimental conditions. Implications for possible gender of rater effects in behavioral assessment procedures as well as for the impact of beliefs on nonverbal communication are discussed.     

PARTY POLITICS AND THE PRICE OF PAYOLA

The literature contains two competing views of the role of political parties: parties are treated either as associations of interest groups supported to the degree that they offer electoral support in the lawmaker's district, or as expressions of the personal ideologies of the lawmakers. In this paper parties are treated as bargaining agents for groups of lawmakers in their dealings with interest groups. Interest groups are depicted buying votes on proposals where those votes are cheapest. Parties are combinations of consistently low-price vote suppliers. The theory has empirical power that discriminates between it and the two competing models.

How Parenting Style Affects False Belief Understanding

This study investigated whether mothers facilitate false belief understanding, and if so, what strategies are particularly relevant. The mothers of 64 3- and 4-year-olds were given questionnaires eliciting information about mother's education, mother's occupation, number of younger and older siblings, the time the child spends with mother, and about how mothers deal with five disciplinary situations with their child. Three variables were positively correlated with belief understanding: age, number of older siblings, and number of times mothers said they would respond to the disciplinary situations by asking the child to reflect on the victim's feelings (How Feel responses). These three variables had an independent effect on belief understanding because each was significant after accounting for the influence due to the other two variables. In contrast, there was no significant positive relation between belief understanding and mothers who engaged their child in general discussion and exploration of the disciplinary issues, or who simply reprimanded the child without discussing the situation. The effects for number of older siblings and How Feel responses remained even after the influence due to the child's age, verbal mental age, time spent with the mother, and number of younger siblings was accounted for. The results are consistent with recent research showing that parent-child relations may be important for theory of mind understanding. More importantly, they provide insight into a specific strategy by which parents may help children learn about mental states.     

Adolescents' attention to traditional and graphic tobacco warning labels: an eye-tracking approach

The objective of this study was determine if the inclusion of Canadian-style graphic images would improve the degree to which adolescents attend to, and subsequently are able to recall, novel warning messages in tobacco magazine advertising. Specifically, our goal was to determine if the inclusion of graphic images would (1) increase visual attention, as measured by eye movement patterns and fixation density, and (2) improve memory for tobacco advertisements among a group of 12 to 14 year olds in the western United States. Data were collected from 32 middle school students using a head-mounted eye-tracking device that recorded viewing time, scan path patterns, fixation locations, and dwell time. Participants viewed a series of 20 magazine advertisements that included five U.S. tobacco ads with traditional Surgeon General warning messages and five U.S. tobacco ads that had been modified to include non-traditional messages and Canadian-style graphic images. Following eye tracking, participants completed unaided- and aided-recall exercises. Overall, the participants spent equal amounts of time viewing the advertisements regardless of the type of warning message. However, the warning messages that included the graphic images generated higher levels of visual attention directed specifically toward the message, based on average dwell time and fixation frequency, and were more likely to be accurately recalled than the traditional warning messages.
