Adolescent Female Identify Development

The purpose of this study was to (a) add to the current literature on female identity development and (b) determine whether a gender specific pattern of identity formation is evident in females during their early and middle adolescent years. The Measures of Psychosocial Development (MPD) was administered by graduate students to 317 males and 332 females in sixth, eighth, tenth, and twelfth grades from schools in a small and a mid-sized mid-western city. The schools were selected because they were representative of the racial/ethnic status of the cities (African American, 12%, Asian American, 4%, European, 63%, Latino, 10%, and Native American, 6%; 5% did not state their ethnicity). The results of the two by four analyses of variance (gender by grade) indicated that females blend interpersonal and intrapersonal identity development, whereas males appear to develop only intrapersonal identity. Limitations and recommendations for future research are also included.     

Transfer of pattern recall skills may contribute to the development of sport expertise

Superior recall of domain‐specific patterns is well established as a defining attribute of expert performers. Recent studies on the developmental histories of expert team ball sport players (e.g. Baker, Côté, & Abernethy, 2003a ) also suggest that experts characteristically receive exposure to a wide range of sports in their developing years and that this related sports experience may reduce the amount of sport‐specific training needed to become an expert. This study examined whether the facilitation of expertise associated with other sport experience might arise from positive transfer of pattern recall skills from one sport to another. Expert netball, basketball and field hockey players and experienced non‐experts performed a recall task for patterns of play derived from each of these sports. Experts from sports different to those shown in the presented pattern consistently outperformed non‐experts in their recall of defensive player positions, suggesting some selective transfer of pattern recall skills may indeed be possible.

The Relational Health Indices: A Study of Women's Relationships

A new measure of women's relationships, the Relational Health Indices (RHI), comprises three scales that assess growth-fostering connections with peers, mentors, and communities. The RHI was developed using the Relational Model (Jordan, Kaplan, Miller, Stiver, Surrey, 1991; Miller & Stiver, 1997), a theory of women's psychological development. The 37-item measure assesses three conceptual dimensions of growth-fostering relationships: engagement, authenticity, and empowerment/zest. This study examined the psychometric properties of the RHI with a group of 450 students at a women's liberal arts college, providing evidence for the reliability, validity, and utility of the new measure. The factor analyses confirmed a three-subscale structure: engagement, authenticity, empowerment/zest. The RHI's components generally demonstrate good overall internal consistency. Furthermore, associations between RHI scales and convergent validation scales were significant and in the direction hypothesized. Correlations with adjustment scales varied across the RHI components. The RHI has potential for enriching our understanding of important, subtle qualities and complex dynamics of both dyadic and group relationships, especially among women. The instrument is available for use by researchers interested in continuing the scale and theory development.     

Parenthood and productivity: A study of demands, resources and family-friendly firms

We examine how the presence of children is related to women’s and men’s productivity. We hypothesize family demands, family resources, and family-friendly workplaces are also related to productivity. Productivity for 670 Alberta law firm lawyers is analyzed using a standardized measure of productivity referred to as billable hours. The results suggest that mothers with school-aged children are less productive than non-mothers, whereas fathers with preschool-aged children are more productive than non-fathers. While time spent on household and childcare tasks significantly reduces women’s productivity, we find little support for the benefits of family resources or working in a family-friendly firm for women. Rather, fathers seem to benefit more: family resources are positively related to their productivity and family-friendly benefits allow them more time for leisure. These results support the assumption that having children is negatively related to women’s productivity but challenges the belief that family-friendly policies are primarily beneficial only to mothers trying to balancing work and family.     

Beta‐binomial ANOVA for multivariate randomized response data

There is much empirical evidence that randomized response methods improve the cooperation of the respondents when asking sensitive questions. The traditional methods for analysing randomized response data are restricted to univariate data and only allow inferences at the group level due to the randomized response sampling design. Here, a novel beta‐binomial model is proposed for analysing multivariate individual count data observed via a randomized response sampling design. This new model allows for the estimation of individual response probabilities (response rates) for multivariate randomized response data utilizing an empirical Bayes approach. A common beta prior specifies that individuals in a group are tied together and the beta prior parameters are allowed to be cluster‐dependent. A Bayes factor is proposed to test for group differences in response rates. An analysis of a cheating study, where 10 items measure cheating or academic dishonesty, is used to illustrate application of the proposed model.     

Precocity of fine motor control and task context: hitting a ball while stepping

To determine if children under 5 years were able to intercept a moving object while stepping, the authors had 9 3-year-olds hit a ball that the authors dropped from a ramp from 5 heights (1.5, 2.0, 2.5, 3.0, and 3.5 m). The statistical analysis showed that the hand movement times were similar regardless of ball rolling heights and that the hand initiation times were dependent on the ball rolling times. Children under 5 years were able to hit a moving ball, and they performed this hitting according to a temporal coupling between ball displacements and the hand contact with it. The participants' behavior of hitting while stepping supports the idea that the motor system implicitly knows what the cognitive system ignores.     

The error statistical philosopher as normative naturalist

We argue for a naturalistic account for appraising scientific methods that carries non-trivial normative force. We develop our approach by comparison with Laudan’s (American Philosophical Quarterly 24:19–31, 1987, Philosophy of Science 57:20–33, 1990) “normative naturalism” based on correlating means (various scientific methods) with ends (e.g., reliability). We argue that such a meta-methodology based on means–ends correlations is unreliable and cannot achieve its normative goals. We suggest another approach for meta-methodology based on a conglomeration of tools and strategies (from statistical modeling, experimental design, and related fields) that affords forward looking procedures for learning from error and for controlling error. The resulting “error statistical” appraisal is empirical—methods are appraised by examining their capacities to control error. At the same time, this account is normative, in that the strategies that pass muster are claims about how actually to proceed in given contexts to reach reliable inferences from limited data.
