Developmental Co-ordination Disorder and Emerging Adulthood: Not Just a Motor Disorder

This paper discusses the focus of the special edition on emerging adulthood in DCD and how the different papers present the increasing awareness not only of the disorder but the continuation of difficulties into adulthood. It highlights the varying presentation at this stage and the impact these difficulties have on quality of life. Finally, it calls for further research to be undertaken to increase the understanding of DCD for both clinicians and researchers.     

Driver responses to motorcycle and lead vehicle braking events: The effects of motorcycling experience and novice versus experienced drivers

In many countries, motorcyclists are over-represented in traffic collision fatalities and injuries compared to vehicle registrations. Why drivers may violate the right-of-way of motorcyclists traveling as lead vehicles in front of drivers is empirically examined in two studies that were conducted with a moderate-fidelity driving simulator. The purpose of the first study was to determine if drivers, who also held a motorcycle license (N = 16), drove cars differently than regular drivers (N = 16) around motorcycles. The two groups did not differ on responses to motorcycling braking events, which was consistent with previous research on car following. The second study compared the driving performance of sixteen novice teenage drivers (M = 16.2 years of age) to 15 experienced drivers (M = 32.9) over the span of six monthly simulator sessions. Novice drivers’ perception response times (PRT) to the braking events were significantly longer than those of the experienced drivers. PRTs to motorcycle and lead vehicle braking events decreased over sessions. For all participants, PRTs to the motorcycle events were longer than to the car events. The implications of these results for motorcyclists and drivers with different levels of experience are discussed.     

Malleability in communal goals and beliefs influences attraction to stem careers: evidence for a goal congruity perspective

The goal congruity perspective posits that 2 distinct social cognitions predict attraction to science, technology, engineering, or mathematics (STEM) fields. First, individuals may particularly value communal goals (e.g., working with or helping others), due to either chronic individual differences or the salience of these goals in particular contexts. Second, individuals hold beliefs about the activities that facilitate or impede these goals, or goal affordance stereotypes. Women's tendency to endorse communal goals more highly than do men, along with consensual stereotypes that STEM careers impede communal goals, intersect to produce disinterest in STEM careers. We provide evidence for the foundational predictions that gender differences emerge primarily on communal rather than agentic goals (Studies 1a and 3) and that goal affordance stereotypes reflect beliefs that STEM careers are relatively dissociated from communal goals (Studies 1b and 1c). Most critically, we provide causal evidence that activated communal goals decrease interest in STEM fields (Study 2) and that the potential for a STEM career to afford communal goals elicits greater positivity (Study 3). These studies thus provide a novel demonstration that understanding communal goals and goal affordance stereotypes can lend insight into attitudes toward STEM pursuits.     

The gray area: exploring attitudes toward infidelity and the development of the Perceptions of Dating Infidelity Scale

Prior research has distinguished between emotional versus sexual infidelity. Two studies examined the development of the Perceptions of Dating Infidelity Scale (PDIS) to assess attitudes toward specific behaviors that constitute these types of infidelity in romantic relationships. Exploratory and confirmatory factor analyses indicated three factors to the scale: Ambiguous, Deceptive, and Explicit behaviors. In both studies, there were gender differences on ratings of the behaviors. The construct validity of the scale was assessed with measures of sociosexual orientation, guilt, and coping with unwanted sexual situations. It was found that the Ambiguous behaviors were positively correlated with avoidance of unwanted sexual situations, while the Deceptive and Explicit scales were positively correlated with guilt and avoidance and negatively associated with an unrestricted sociosexual orientation and acting on attractions toward friends.     

The role of common motor responses in stimulus categorization by preschool children

The purpose of this study was to assess the role of common motor responses as the "speaker" behavior on stimulus class formation, and the emergence of functional classes. Experiment 1 examined whether training one motor response to a set of three stimuli and a second motor response to another set of three stimuli would result in correct category-sort responses for 5 typically developing preschool children. Three of the children passed the categorization tests. Experiment 2 examined whether the classes formed in Experiment 1 were functional classes, and whether participants who did not pass categorization tests in Experiment 1 would do so following common vocal tact training. The 2 participants who failed categorization tests in Experiment 1 passed these tests in Experiment 2, although none of the participants passed the tests for functional classes. The results of the current study did not unequivocally support the naming hypothesis. Future research should therefore evaluate other possible sources of control that aid in stimulus categorization.     

Parenting and child body mass index: Longitudinal investigation of maternal and paternal influence

The aim of this study was to investigate the cross‐sectional and longitudinal relationships between general parenting and body mass index (BMI) status of children between the ages of 4 and 7 in Australia. A nationally representative sample of 4,423 children (49% female) and their parents was used for the present study. Measures of parental demandingness and responsiveness were completed by parents at child age 4–5 years. Height and weight measurements of children were taken at child age 4–5, and again at 6–7, from which BMI status was calculated. No influence of mothers' parenting on child BMI status was shown, and fathers' responsiveness was found to be predictive of increased risk for overweight/obesity at 6–7 years. While the present study is complicated by measurement issues, findings suggest that increased risk for overweight in young children may be associated with responsiveness in fathers. Obesity prevention programs involving parents should take into account the influence of fathers' parenting on child BMI status.     

When partner caring leads to sharing: Partner responsiveness increases expressivity, but only for individuals with low self-esteem

Two studies examined whether perceiving a partner as responsive leads people to be more expressive with that partner, and whether the effects of perceived partner responsiveness on expressivity are moderated by self-esteem. In Study 1, female undergraduates with high or low self-esteem disclosed to a fictitious partner about a sad event. Participants either received an understanding, caring, and validating written response from their ostensible partner or did not receive a response. In Study 2, participants wrote an email, supposedly to another participant, about a sad event and received either a highly responsive or a non-responsive email response. In both studies, partner responsiveness increased expressivity among individuals with low self-esteem but not among individuals with high self-esteem. These results provide the first experimental evidence for Reis and Shaver's (1988) theorizing about responsiveness and self-disclosure.     

Studying Ideological Groups Online: Identification and Assessment of Risk Factors for Violence

Recent acts of violence have demonstrated the impact of violent ideological groups worldwide. However, the systematic study of these groups is somewhat limited. The Internet is a valuable tool for investigating ideological group behavior because it is easily accessible and commonly used by these groups. This study attempted to extend previous research by examining online message boards to assess processes particular to ideological group membership. A content analysis was conducted on several group process variables using 29 groups with message boards. A Kruskal‐Wallis test with follow‐up pairwise comparisons was used to find that violent ideological groups differed from nonviolent ideological and nonviolent nonideological groups on 7 group process variables and 3 content variables. Implications are discussed.     

Encouraging Active Classroom Discussion of Academic Integrity and Misconduct in Higher Education Business Contexts

The present study assessed business students’ responses to an innovative interactive presentation on academic integrity that employed quoted material from previous students as launching points for discussion. In total, 15 business classes (n = 412 students) including 2nd, 3rd and 4th year level students participated in the presentations as part of the ethics component of ongoing courses. Students’ perceptions of the importance of academic integrity, self-reports of cheating behaviors, and factors contributing to misconduct were examined along with perceptions about the presentation. Discussion sessions revealed that academic misconduct is a complex issue. For example, knowledge of what constitutes misconduct was not consistent across domains (e.g. exam contexts versus group work), penalties were not wholly known, and there was variation in perceived responsibility for reporting and representing academic integrity. Survey measures revealed that self-reported academic misconduct was more prevalent than expected with only 7.5% of students indicating they had never cheated in any way. Furthermore, results showed gender and year of study as predictive factors for issues related to academic misconduct. In general, students were receptive to this form of presentation. The implications of such instructional interventions for enhancing ethical behaviors in higher education classrooms are discussed.     

Infant physiological regulation and maternal risks as predictors of dyadic interaction trajectories in families with a preterm infant

This longitudinal study examined predictors of rates of growth in dyadic interaction quality in children born preterm who did not experience significant neurological findings during neonatal intensive care unit (NICU) hospitalization. Multiple methods were used to collect data from 120 preterm infants (48% girls, 52% boys) and their mothers. Infant heart rate variability (HRV), gestational age, neonatal health, feeding route, and maternal socioeconomic (SES) risks were assessed at NICU discharge (mean of 36 weeks postconception). Mother-child interactions were observed at 4, 9, 16, and 24 months postterm and analyzed with hierarchical linear modeling. On average, children's quality of play, interest, and attention increased over time while their dysregulation and irritability decreased, whereas average maternal positive affect and involvement declined in quality (ps < .05), although there was individual variation in rates of change. Mothers of infants with higher postfeeding HRV (i.e., vagal regulation) exhibited less decrease in positive affect and involvement between 4 months and 24 months, compared with mothers of infants with lower HRV (p < .05). Although infants with higher postfeeding HRV showed less positive affect and communication at 4 months, they exhibited significantly greater increases in positive affect and social competence and decreases in dysregulation and irritability between 4 months and 24 months, compared with infants with lower HRV (ps < .05). Dyads experiencing more SES risks showed less optimal interactions at 4 months; this difference remained as children grew older (ps < .05). Results have implications for our understanding of social development in preterm infants.
