Effects of Movement Improvisation and Aerobic Dancing on Motor Creativity and Divergent Thinking

Creativity is considered to be an embodied concept, where internal psychological and external behavioral processes are intertwined. Creativity enhancement programs often target the cognitive side of this bi‐dimensionality leaving the impact of motor interventions underexplored. To address this gap in the literature, we tested the effectiveness of two motor programs on motor creativity and divergent thinking (verbal and figural). A total of 92 college students (M_age = 25.36, SD = 2.66) were randomly allocated to a movement improvisation, an aerobic dance, or a control condition. Participants in both motor programs took part in ten 30‐minute classes twice a week over a period of 5 weeks. The findings revealed a significant effect of the motor programs on motor fluency and flexibility. Movement improvisation yielded the greatest effects on those variables, followed by aerobic dancing and control condition. Movement improvisation also impacted significantly more figural originality than the control condition. However, the effects were limited to the motor domain and failed to transfer into other divergent thinking variables. The findings highlighted the contribution of movement programs to creative potential development, and the imperative role of a non‐judgmental environment, where individuals are free to move spontaneously.     

Relations Between Parents’ Anxiety Symptoms,Marital Quality,and Preschoolers’ Externalizing and Internalizing Behaviors

Our objective was to expand understanding of the associations between fathers’ and mothers’ anxiety symptoms, their perceptions of marital quality, and their children’s maladjustment behaviors. Sixty Israeli families with a child aged 3–5 participated. Mothers and fathers completed self-report questionnaires assessing parents’ anxiety symptoms, marital dissatisfaction, and marital overt conflict, and child internalizing and externalizing behaviors. The actor–partner interdependence mediation model (APIMeM) design with distinguishable dyads within a path analysis framework was used. Findings showed that marital dissatisfaction of both mothers and fathers partially mediated the links between mothers’ anxiety and child behaviors. For externalizing behaviors, actor and partner effects were found, so that mothers’ anxiety symptoms predicted mothers’ own marital dissatisfaction (actor effect) and fathers’ marital dissatisfaction (partner effect), which, in turn were linked with children’s externalizing behaviors. As for internalizing behaviors, only actor effect was found, so that mothers’ anxiety symptoms were linked with maternal dissatisfaction, which, in turn, was linked with child internalizing behaviors. For fathers’ anxiety symptoms, the APIMeM indicated only direct effects on both internalizing and externalizing behaviors. These findings highlight the risk associated with parental anxiety and the contribution of the marital relations to children’s adjustment and are discussed in light of Bronfenbrenner’s ecological model and Emotional Security Theory.     

Predictors of aerobic physical activity and resistance training among Canadian adults with type 2 diabetes: An application of the Protection Motivation Theory

BackgroundIt is well established that both aerobic physical activity (PA) and resistance training are essential in the treatment and management of type 2 diabetes (T2D), but few studies have examined the determinants of both modes of PA in the same sample.PurposeThe main objective was to investigate the utility of the Protection Motivation Theory (PMT) in predicting aerobic PA and resistance training in a population sample of T2D adults.MethodsA total of 244 individuals completed self-report PMT constructs of vulnerability, severity, fear, response efficacy, self-efficacy and intention, and a 3-month follow-up that assessed aerobic PA and resistance training.ResultsPMT explained 19% (p < .001) and 20% (p < .001) of the variance respectively for aerobic PA and resistance training behaviour. Significant associations were found between self-efficacy (β = 0.45, p < .001) and gender (β = 0.15, p < .05) for aerobic PA, and self-efficacy (β = 0.48, p < .001) and age (β = 0.17, p < .05) for resistance training. PMT accounted for 43% (p < .001) and 56% (p < .001) of the variance respectively for aerobic PA and resistance training intentions. For aerobic PA, response efficacy (β = 0.14, p < .05) and self-efficacy (β = 0.59, p < .001) were significantly associated with intention, while response efficacy (β = 0.23, p < .001), self-efficacy (β = 0.64, p < .001) and age (β = 0.10, p < .05) were significantly related with resistance training intention.ConclusionsNone of the unique constructs of the PMT (i.e., perceived vulnerability, severity and fear) were significant with either aerobic and resistance training intention. These results may guide the development of effective PA interventions in people with T2D.     

Gaining Control Over Traumatic Experiences: The Role of Guilt in Posttraumatic Stress Disorder

The present study explores the relationship between guilt, sense of control, and posttraumatic stress disorder. Seventy-eight participants who had experienced a traumatic event completed the following self-report measures online: the Posttraumatic Stress Diagnostic Scale, the Guilt Cognitions subscale of the Trauma-Related Guilt Inventory, the Posttraumatic Cognitions Inventory, and Sense of Control During the Trauma. Results revealed that “behavioral self-blame” that refers to functioning during the trauma, positively correlated with posttraumatic stress symptoms. However, when Sense of Control During the Trauma was introduced into the analysis, this correlation appeared only for participants who had experienced lack of control during the traumatic event. Among the participants who had experienced a sense of control, no such link was found. Results suggest that guilt may be produced to avoid feelings of helplessness following the trauma, because guilt conveys a sense of control.     

The application of the random regret minimization model to drivers’ choice of crash avoidance maneuvers

This study explores the plausibility of regret minimization as behavioral paradigm underlying the choice of crash avoidance maneuvers. Alternatively to previous studies that considered utility maximization, this study applies the random regret minimization (RRM) model while assuming that drivers seek to minimize their anticipated regret from their corrective actions. The model accounts for driver attributes and behavior, critical events that made the crash imminent, vehicle and road characteristics, and environmental conditions. Analyzed data are retrieved from the General Estimates System (GES) crash database for the period between 2005 and 2009. The predictive ability of the RRM-based model is slightly superior to its RUM-based counterpart, namely the multinomial logit model (MNL) model. The marginal effects predicted by the RRM-based model are greater than those predicted by the RUM-based model, suggesting that both models should serve as a basis for evaluating crash scenarios and driver warning systems.     

Planning maximally smooth hand movements constrained to nonplanar workspaces

The article characterizes hand paths and speed profiles for movements performed in a nonplanar, 2-dimensional workspace (a hemisphere of constant curvature). The authors assessed endpoint kinematics (i.e., paths and speeds) under the minimum-jerk model assumptions and calculated minimal amplitude paths (geodesics) and the corresponding speed profiles. The authors also calculated hand speeds using the 2/3 power law. They then compared modeled results with the empirical observations. In all, 10 participants moved their hands forward and backward from a common starting position toward 3 targets located within a hemispheric workspace of small or large curvature. Comparisons of modeled observed differences using 2-way RM-ANOVAs showed that movement direction had no clear influence on hand kinetics (p < .05). Workspace curvature affected the hand paths, which seldom followed geodesic lines. Constraining the paths to different curvatures did not affect the hand speed profiles. Minimum-jerk speed profiles closely matched the observations and were superior to those predicted by 2/3 power law (p < .001). The authors conclude that speed and path cannot be unambiguously linked under the minimum-jerk assumption when individuals move the hand in a nonplanar 2-dimensional workspace. In such a case, the hands do not follow geodesic paths, but they preserve the speed profile, regardless of the geometric features of the workspace.     

The Role of Biodata and Intelligence in the Predictive Validity of Assessment Centres

The present study assessed three of Klimoski and Brickner's ¹ 1 See Klimoski and Brickner (1987) in reference list.
explanations for assessment centres' predictive validity: criterion contamination, the influence of biodata, and the effect of assessed intellectual level. Data were collected in a major Israeli industrial organisation on the job performance and advancement of 91 managers who had participated in an assessment centre four to seven years earlier. Little empirical support was garnered for Klimoski and Brickner's claims. Assessment centre scores were found to be similarly correlated in a significant fashion with both contaminated and uncontaminated criteria of later management performance. Although biodata and intelligence variables were correlated with assessors' evaluations, they did not notably contribute to the predictive validity of assessment centre scores. It seems that information reached by observing behaviours reflected during exercises and simulations are the main factors affecting the validity of assessment centres.     

Development of the Injury Perceptions Questionnaire (InjPQ)

Objectives: Injuries are major causes of morbidity and mortality in the population. Given the central role of perceptions in self-regulation of health conditions, it is important to investigate how they are perceived. This article describes the development of the Injury Perceptions Questionnaire (InjPQ).

Methods: A concurrent study in a diverse sample of injured individuals (n = 333). The internal structure and the reliability (Cronbach’s α) of InjPQ sub-scales were explored by factor analyses. Relationships between injury perception dimensions and equivalent illness perception scales and outcome measures (self-assessed health; physical, emotional and social functioning; depression, anxiety and somatisation; satisfaction with life) were investigated.

Results: The InjPQ was found to represent the following perception scales: injury identity composed of social and body part components, PTSD symptoms, Injury event, Injury specific emotions, Injured self-image, Positive consequences, Responsibility/guilt, Coping, Time distance, Dependency, Healthy self, External attributions and Injury risk factors. The reliability and construct validity of the scales were found adequate.

Conclusions: Injury perceptions can be reliably measured. While partly overlapping with equivalent illness perception scales, the InjPQ depicts cognitive dimensions unique to injury that add significantly to explaining variance in outcomes. The InjPQ is recommended for research and clinical use as a measure of injury perceptions.     

Gift Giving at Israeli Weddings as a Function of Genetic Relatedness and Kinship Certainty

This study examines gift giving at Israeli weddings. In accordance with kin selection theory, we hypothesized that wedding guests possessing greater genetic relatedness to the newlyweds would offer greater sums of money as wedding gifts. We also hypothesized that family members stemming from the maternal side (where the genetic lineage has higher kinship certainty) would offer the newlyweds more money than those stemming from the paternal side. Data on the monetary gift sums of the wedding guests from 30 weddings were collapsed according to two criteria: (a) genetic relatedness (0%, 6.25%, 12.5%, 25%, and 50%) and (b) kinship certainty (maternal or paternal lineage). Both hypotheses were supported. We discuss the implications of these data in understanding family dynamics, as well as practical applications associated with the marketing of gifts.
