Coincidence timing of finger, arm, and whole body movements

Two experiments investigated the effects of different types of movement responses on coincidence timing skill. The view was taken that the sensory-motor integration of the movement responses would be reflected in the accuracy and consistency of anticipation timing. A Bassin anticipation timer provided a light stimulus velocity of 3 mph for both experiments and the movements studied included a simple key press using a finger, an arm movement to a key press, and whole body movements culminating with a kick or step to a target. The experiments were modelled closely on the seminal study by Grose (1967). The results of Exp. 1 supported our prediction by demonstrating superiority of the finger task over the two larger movements for all measures of coincidence timing ability. The purpose of Exp. 2 was to compare the slightly different versions of the whole body task-that used in the first experiment and that used by Grose (1967). The results confirmed the close similarity of the two movement tasks and re-affirmed the results of Exp. 1. Exp. 2 also investigated sex effects on coincidence timing ability and, in contrast to previous evidence indicating that females perform with less accuracy and consistency than do males, no significant differences were found. Analysis of practice effects showed that, although there were no significant improvements over trial blocks in Exp. 1, there were significant improvements in Exp. 2. Comparisons with other research suggests that repeated practice in solving a coincident timing problem using whole body movements can lead to improved performance. In general, the findings are consistent with the constructs of action theory and emphasize the roles perceptual and movement variables have in defining situational constraints. Also, findings indicate that proficiency in coincidence anticipation appears to be influenced by the planning and organisation required for movement execution.     

Assessing Religious Faith in Medical Patients: Cross-Validation of the Santa Clara Strength of Religious Faith Questionnaire

Growing attention has focused on the relationship between religiosity and health outcomes. However, research has been constrained by the limited availability of measures suitable for use with medical patients. This study examined the psychometric properties of the Santa Clara Strength of Religious Faith Questionnaire (SCSORF) in two well-defined samples of medical patients, representing a range of illness severity: 1) 175 women seen at a gynecology clinic; and 2) 104 cancer patients treated at a bone marrow transplantation program. Evidence for convergent validity was demonstrated by moderately high correlations with other measures of religious involvement. Divergent validity was demonstrated by small associations with social desirability. The measure was not strongly associated with demographic background or medical variables. Modest correlations with conceptually-related measures commonly used in health research (e.g., social support, optimism, existential meaning, purpose in life) further supported the divergent validity of the instrument. Results suggest that this may be a useful, concise measure for assessing religious involvement in medical patients.     

Is Therapeutic Alliance Influenced by a Feminist Approach to Therapy?

Although the feminist critique of marriage and family therapy has been a significant part of the literature for many years, its impact has been blunted by two criticisms. The first suggests that the feminist critique lacks empirical support. The second suggests that the feminist critique promotes an alliance with women clients at the expense of men. The first criticism has been addressed in recent years. The present study examined the relationship between feminist principles and therapeutic alliance. Results suggest that feminist principles actually enhance therapeutic relationship for men clients but has no effect on therapeutic relationship for women clients.of the Marriage and Family Therapy Program     

Conduct Disorder in Girls: A Review of the Literature

The study of Conduct Disorder (CD) has primarily been limited to boys. The lack of research resulted from a premise that CD in girls was rare. However, CD in girls is a relatively common psychiatric diagnosis, and appears to be associated with several serious outcomes, such as Antisocial Personality Disorder and early pregnancy. Understanding gender differences in the course and severity of CD may lead to important information about etiology. Empirical studies on precursors, developmental course, risk factors and treatment for CD in girls are reviewed, while highlighting similarities and differences between girls and boys. Generally, CD symptoms in girls are stable. Precursors to CD in girls probably include Oppositional Defiant Disorder and temperamental factors, but also may include certain negative cognitions. What distinguishes CD in girls is the high risk they have to develop comorbid conditions, especially internalizing disorders. Risk factors for CD in girls partly overlap with those known for boys, but some factors appear to be highly salient for girls. Finally, there may be some significant effects of gender on treatment efficacy. Implications of these findings for future etiologic research are discussed.     

Misconduct in science: Controversy and progress

Conclusion It is clear that the concept of scientific misconduct continues to evolve. As always it is the goal of Science and Engineering Ethics to move the discussion forward, to encourage and facilitate discussion of the ethical issues and problems that practicing scientists and engineers encounter in the course of pursuing their professions. This collection of articles and commentaries provides a variety of perspectives that we expect will facilitate communication among and within the groups who must participate in this evolution.

A Comparative Study of Educational and Cultural Determinants of Adolescent Values

This article compares the results of three surveys in adolescent values. The subjects comprise young people with a modal age of 15 years from three countries‐‐England, Saudi Arabia and the United States. The contrasting educational systems of these countries are described with particular reference to the place of religious education within their curricula. An open‐ended questionnaire, designed to prompt statements from young people about their values, is introduced and its provenance is described. Similarities but also significant differences are found in the values expressed across the three cultures. Most marked is the high value placed on parents and friendship by the English young people, the importance attached to being well adjusted and feeling good about oneself in the American group and the prominence given to Islam by the Saudi Arabian adolescents.     

Potential Bone-Marrow Donors and Their Spouses: The Effects of Volunteerism on Distress Levels1

The current study sought to provide a better understanding of the reactions of bone-marrow volunteers to the possibility of donating by examining these volunteers in the context of their closest relationships. Using Tesser's (1988) self-evaluation maintenance (SEM) model as a guide, we examined the influence of spouses who are also volunteers on each member of the couple's distress levels and on the marrow volunteer's ambivalence about donating. We also examined the independent effects of known risk factors for donation-related distress and the combined effects of spouse volunteer status and these risk factors on distress levels. Questionnaire data were collected from 278 couples selected from 39 bone-marrow donor centers. Results demonstrated that when spouses of potential donors were engaged in any type of volunteer activity, members of the couple felt greater anxiety than when spouses were not volunteers. Additionally, other variables were found to have a conjoint effect with spouse volunteer status on volunteer and spouse anxiety levels.     

Temporal dynamics of anxiety-related attentional bias: is affective context a missing piece of the puzzle?

Previous research has demonstrated that anxious individuals attend to negative emotional information at the expense of other information. This is commonly referred to as attentional bias. The field has historically conceived of this process as relatively static; however, research by [Zvielli, A., Bernstein, A., &; Koster, E. H. W. (2014). Dynamics of attentional bias to threat in anxious adults: Bias towards and/or away? PLoS ONE, 9(8), e104025; Zvielli, A., Bernstein, A., &; Koster, E. H. W. (2015). Temporal dynamics of attentional bias. Clinical Psychological Science, 3(5), 772–788.], and others, challenges this assumption by demonstrating considerable temporal variability in attentional bias amongst anxious individuals. Still, the mechanisms driving these temporal dynamics are less well known. Using a modified dot-probe task, the present study examined the impact of two relevant contextual variables- affective valence and trial repetition. Affective context was instantiated by the presentation of negative versus neutral pictures before each trial, while repetition context was achieved via the presentation of the valenced pictures in either a blocked- or mixed-trial design. Results indicate that individuals with higher trait-anxiety levels were significantly more influenced by blocked presentations of negative affective information, leading to greater temporal fluctuations in attentional bias. Furthermore, our findings provide additional evidence that attentional bias is best conceptualised as dynamic and variable, and that an individual’s affective experience is one factor that regulates attentional bias dynamics. Implications relating to theoretical and methodological factors are discussed.     

Constructing Difference: Lego® Set Narratives Promote Stereotypic Gender Roles and Play

LEGO® construction sets are a staple in many children’s lives. Given worldwide distribution, generations of children have grown up playing with these brightly colored, interlocking plastic bricks. Historically marketed to all children, the LEGO® Group has begun targeting male and female consumers differentially with the introduction of product lines such as LEGO® City and LEGO® Friends. Although the packaging, marketing, brick colors, and characters have changed, little is known about whether these product series encourage differences in the way boys and girls play. This content analysis compared the play narratives of sets marketed to boys (LEGO® City) and girls (LEGO® Friends). Our analysis found distinct gendered messages that encourage boys to enact various skilled professions, heroism, and expertise, whereas girls are encouraged to focus on having hobbies, being domestic, caring for others, socializing, being amateurs, and appreciating and striving for beauty. Although LEGO® City and Friends sets offer opportunities for construction, they also promote stereotyped gender roles for enacting femininity and masculinity in play. Parents, educators, and practitioners often focus on the educational affordances of LEGO® construction. We recommend that they also consider the other lessons, both explicit and implicit, being taught through gender-specific LEGO® sets.     

Development and Validation of the Female Muscularity Scale

Socially promoted physical appearance ideals for women place increasing importance on muscularity, resulting in growing muscularity concerns among traditional college-age women. To date, however, instruments for assessing the type of muscularity concerns reported by women are lacking. The aim of the present study was therefore to develop such a scale and examine its psychometric properties among a sample of young women. Findings from an exploratory factor analysis (n = 235) and a confirmatory factor analysis (n = 130) revealed a two-factor structure, including a five-item Attitudes subscale (α = .89) and a five-item Behaviors subscale (α = .90), which were moderately correlated, r = .50. In addition, the scale demonstrated good 2-week test-retest reliability (r = .76), and the subscales revealed moderate-to-large associations with body image concerns, drive for thinness, and exercise engagement, indicating concurrent validity. Thus the new Female Muscularity Scale is a useful and promising tool for assessing muscularity concerns among young women, and it may help toward understanding the role of pressures to achieve a toned body in the development of body image, eating, and exercise disorders.
