Behavioral phenotype of individuals with Down syndrome

Evidence is reviewed for a developmentally-emerging behavioral phenotype in individuals with Down syndrome that includes significant delay in nonverbal cognitive development accompanied by additional, specific deficits in speech, language production, and auditory short-term memory in infancy and childhood, but fewer adaptive behavior problems than individuals with other cognitive disabilities. Evidence of dementia emerges for up to half the individuals studied after age 50. Research issues affecting control group selection in establishing phenotypic characteristics are discussed, as well as the possible genetic mechanisms underlying variation in general cognitive delay, specific language impairment, and adult dementia.

Christian Churches and Immigrant Support in Canada: An Organizational Ecology Perspective

Canada receives roughly 250,000 immigrants each year, and the government spends considerable resources on assisting them to settle and integrate into Canadian society through the agencies they support. Most of these new immigrants settle in Canada’s largest cities, where churches meet specific needs that extend beyond the capacities of government agencies. In smaller centers, churches cover a wide range of services because few government supports are available. Little is known about the work of churches in Canada in spite of their importance to immigrant settlement and integration. In this study, we examine the services offered to immigrants by Canadian Christian churches. We show how the service provision of Christian churches is constrained by other organizations and groups in their environment, in ways consonant with the organizational ecology framework. Specifically, churches service the needs of immigrants by adapting to specific niche needs and by filling in gaps left by other service providers.     

A Closer Look at the Yardstick: A New Discount Rate Measure with Precision and Range

In intertemporal choice research, choice tasks (i.e., choosing between $80 today and $100 in a year) are often used to elicit a discount rate. The discount rate derived from a choice task, however, is largely restricted by the granularities and ranges of the questions asked. We examined this restriction in three popular discount rate measurements using simulations and experiments, and we propose an alternative procedure (Three‐option Adaptive Discount rate measure (ToAD)), which is capable of measuring a wide range of discount rates (from approximately .035% to 350 000% annual percentage rate) with high precision using 10 questions, in under a minute. ToAD can be easily implemented in online surveys (i.e., Qualtrics). Copyright © 2015 John Wiley & Sons, Ltd.     

Revisiting the Relationship Between Marriage and Wellbeing: Does Marriage Quality Matter?

This paper revisits the marriage and wellbeing relationship using variables reflecting marriage quality and data from the US, the UK and Germany. People in self-assessed poor marriages are fairly miserable and much less happy than unmarried people, even in the first year of marriages. However, people in self-assessed good marriages are even happier than the literature suggests. Women show greater range of responses to marriage quality than men. The effect of employment status and subjective health on happiness and the marriage effects on interpersonal trust and mental health change dramatically when marriage quality is controlled for. A strong link from happiness to marriage does not exist. However, happier people are more likely to stay single instead of being unhappily married, but less likely to stay single compared to being very happily married and happiness cannot predict staying single versus being pretty happily married.     

Meta-analysis of the relationship between risk perception and health behavior: the example of vaccination.

BACKGROUND: Risk perceptions are central to many health behavior theories. However, the relationship between risk perceptions and behavior, muddied by instances of inappropriate assessment and analysis, often looks weak. METHOD: A meta-analysis of eligible studies assessing the bivariate association between adult vaccination and perceived likelihood, susceptibility, or severity was conducted. RESULTS: Thirty-four studies met inclusion criteria (N = 15,988). Risk likelihood (pooled r = .26), susceptibility (pooled r = .24), and severity (pooled r = .16) significantly predicted vaccination behavior. The risk perception-behavior relationship was larger for studies that were prospective, had higher quality risk measures, or had unskewed risk or behavior measures. CONCLUSIONS: The consistent relationships between risk perceptions and behavior, larger than suggested by prior meta-analyses, suggest that risk perceptions are rightly placed as core concepts in theories of health behavior.     

Stepparents’ Attachment Orientation,Parental Gatekeeping,and Stepparents’ Affinity-Seeking with Stepchildren

Remarried stepfamilies are a sizable portion of American families; in a 2011 Pew Center survey, 42% of respondents reported at least one stepfamily member. Family clinicians and researchers suggest that stepparents’ ability to develop close bonds with stepchildren may be critical to the well-being of couple and family relationships. Using actor-partner interdependence models to analyze dyadic data from 291 heterosexual remarried stepfamily couples, we explored factors related to stepparents’ efforts to befriend their stepchildren. Specifically, we evaluated how remarried parents’ gatekeeping and stepparents’ perceptions of their attachment orientations were associated with their own and their spouse's perceptions of stepparents’ affinity-seeking behaviors. Securely attached stepparents and stepparents with anxious attachment orientations engaged more frequently in affinity behaviors than did stepparents with avoidant attachment orientations; there was no difference between securely attached and anxious stepparents. Stepparents’ reports of parents’ restrictive gatekeeping were strongly and negatively associated with both stepparents’ and parents’ reports of stepparent affinity-seeking (actor and partner effects). Parents’ reports of their own restrictive gatekeeping were also negatively (but more weakly) associated with parents’ reports of stepparent affinity-seeking. Implications for families, clinicians, and relationship researchers and theorists are discussed.     

Attending to the peripheral world while driving

Do inexperienced drivers see less of the world when driving? Previous research suggests that participants detect fewer peripheral targets while watching video clips of dynamic hazardous driving scenes due to increases in foveal demand (i.e. the presence of a hazard), increases in peripheral target eccentricity, and the lack of driving experience. The current study aimed to further explore the role of experience as a key factor in the potential narrowing of spatial attention, and the possibility of differences in the time course of attentional deployment. It was predicted that the amount of narrowing due to central processing demands would change as a function of driving experience, with more experienced drivers suffering less narrowing due to their mastery of central processing demands in road scenes. The data did not support the narrowing hypothesis, though they did support the alternative strategic difference between the driver groups in the time‐course of attentional deployment. Learners seem to suffer attentional degradation in extra‐foveal regions over a longer period of time whereas experienced drivers seem to invest peripheral attention at the hazard location in short but intense bursts.

The Influence of Videoconference Technology and Interview Structure on the Recruiting Function of the Employment Interview: A Field Experiment

This field experiment examined whether interview medium and interview structure affects the attractiveness of organizations, interviewer friendliness and performance. Attractiveness ratings of 25 organizations were provided by 92 real job applicants, assigned to either a face–to–face (FTF) or a videoconference (VC) interview. An interview medium X structure interaction showed FTF applicants were attracted most to organizations who conducted their interviews with less structure, while VC applicants were more attracted to organizations using structured interviews. Interview structure had no effect on applicants’ perception of the interviewer’s performance; however, interviewers’ performance was rated higher for FTF than VC interviews. Applicants were more satisfied with their FTF performance in less structured interviews and more satisfied with their VC performance in highly structured interviews.     

Living and Loving Cybernetics

How we learn to interpret our experiences influences the sorts of experiences we seek. In other words, habits of mind become habits of action. Cybernetics, as a way of thinking, changes how we act. My testimony demonstrates that the appeal of cybernetics remains strong today, for those who are lucky enough to stumble across its beauty, as I was. Cybernetics contributed to the theoretical foundation and conceptualization of my dissertation, and it positively influences my teaching, whether I am teaching cybernetics explicitly or not. While I am fortunate to be able to integrate cybernetics in my work, what delights me most is living it in my every day.
