Do motor ability and handwriting kinematic measures predict organizational ability among children with Developmental Coordination Disorders?

Background and aimChildren with Developmental Coordination Disorders (DCD) exhibit deficient daily performance concealed in their perception–action mechanism. The aim of this study was to analyze behavior organization of children with DCD, in varied tasks that require generating and monitoring mental representations related to space and time inputs/requirements, for achieving better insight about their perception–action mechanism.MethodParticipants included 42 children aged 7–10, half of whom were defined with DCD and half were typically developing (TD). The children were matched for age, gender and school. They were evaluated using the Movement–ABC and performed three handwriting tasks on an electronic tablet that is part of a computerized system (ComPET – Computerized Penmanship Evaluation Tool). In addition, their teachers completed the Questionnaire for Assessing Students’ Organizational Abilities-Teachers (QASOA-T) to assess the children’s daily organizational ability.ResultsSignificant group differences (DCD versus controls) were found for all handwriting kinematic measures across the three handwriting tasks and for the children’s organizational abilities. Motor ability predicted a considerable percentage of the variance of the kinematic handwriting measures (30–37%), as well as a high percentage of the variance of their organizational abilities (67%). The coefficient of variance of the pen tilt added an additional 3% to the prediction of their organizational abilities.ConclusionsThe results of this study exhibited deficient ability among children with DCD in organizing their behavior in varied real-world tasks requiring generation and monitoring representation related to space and time. The significance of the results to understanding the performance mechanism and implication to the clinical field are discussed.     

Less is not always more: The case of the 36-item short form of the Zimbardo Time Perspective Inventory

Recently, a shortened version of the Zimbardo Time Perspective Inventory (ZPTI; Zimbardo & Boyd, 1999) was proposed as a “gold standard” (Sircova et al., 2014, p. 9). In this study, we examined the internal consistency and structural validity of this version of the ZPTI in samples of adolescents from the United Kingdom (N = 913) and the United States (N = 815), and adults from Australia (N = 667). Results provided support for the internal consistency of ZPTI scores, but structural validity analyses indicated poor fit and numerous problematic items. The findings call into question the use of scores on this shortened version of the ZTPI.     

Mindfulness meditation and relaxation training increases time sensitivity

Two experiments examined the effect of mindfulness meditation and relaxation on time perception using a temporal bisection task. In Experiment 1, the participants performed a temporal task before and after exercises of mindfulness meditation or relaxation. In Experiment 2, the procedure was similar than that used in Experiment 1, except that the participants were trained to mediate or relax every day over a period of several weeks. The results showed that mindfulness meditation exercises increased sensitivity to time and lengthened perceived time. However, this temporal improvement with meditation exercises was primarily observed in the experienced meditators. Our results also showed the experienced meditators were less anxious than the novice participants, and that the sensitivity to time increased when the level of anxiety decreased. Our results were explained by the practice of mindfulness technique that had developed individuals’ abilities in devoting more attention resources to temporal information processing.     

Salience-based progression of visual attention: Time course

In a visual search task, visual attention progresses from the most to the least salient item until a target is found. The time course of such salience-based progression remains unclear although the temporal deployment seems as crucial as the spatial deployment. The present study investigated how the general hierarchical pattern takes place. Healthy volunteers were presented with a primed visual search paradigm in which the primes consisted of three items differing in salience for either 33, 50 or 100 ms. Subsequently one of them became the target and participants had to make a judgment about it. In order to progress on the basis of salience, attention seemed first to be captured by the most salient item. Secondly, the first two most salient items seemed both encompassed within the attentional spotlight. At that time, the least salient item seemed inhibited, completing the stepwise progression of attention. In summary, our data suggest that the hierarchical pattern is built up over time through orienting and expansion of the spotlight, and inhibition of the least salient signals. Furthermore, complementary analyses revealed a proximity effect influencing the selection of the next location to visit. As predicted by different computational models, items located closely to the first visited location were more prone to attract attention than distant items but interestingly enough, this effect only applied to the least salient item suggesting a balance between salience and proximity criteria. Critically also, salience and proximity effects seem to have different time courses. Results are only partially explained by current visual attention models and require further investigation.     

The emotional body and time perception

We examined the effects of emotional bodily expressions on the perception of time. Participants were shown bodily expressions of fear, happiness and sadness in a temporal bisection task featuring different stimulus duration ranges. Stimulus durations were judged to be longer for bodily expressions of fear than for those of sadness, whereas no significant difference was observed between sad and happy postures. In addition, the magnitude of the lengthening effect of fearful versus sad postures increased with duration range. These results suggest that the perception of fearful bodily expressions increases the level of arousal which, in turn, speeds up the internal clock system underlying the representation of time. The effect of bodily expressions on time perception is thus consistent with findings for other highly arousing emotional stimuli, such as emotional facial expressions.     

Driving in the fasting month of Ramadan: An observational study on speeding,horn honking,and using seat belts

The aim of this study was to examine how Ramadan, i.e., fasting month for believers of Islam, was associated to observable driving behaviours (i.e., speeding, horn honking, and using seat belts) as compared to non-Ramadan. Observations on speeding, horn honking, and using seat belts were held during and after Ramadan in different times of the day in the same region of the city of Ankara. Speeds of 1885 vehicles were measured by hand held radar on a two-way eight-lane road with a 50 km/h speed limit. Horn honking was recorded at a signalised intersection with a hidden camera when the light turned into green in terms of 510 traffic light cycles. Seat belt wearing of 2106 drivers was observed at the same intersection. Findings indicated that (a) mean speed was lower, (b) honked horns were higher, and (c) seat belt use was lower in Ramadan as compared to non-Ramadan, though each negative driving behaviour was prevalent in both periods. Thus this study showed that the Ramadan period had a limited role on speeding, horn honking, and using seat belts.     

Inhomogénéité des évaluations de durée d’incapacité totale de travail. Comparaison d’évaluations des durées d’incapacité totale de travail entre les médecins légistes,les médecins généralistes et les urgentistes

Setting a total length for time off work is a forensic act that all physicians must be able to perform. Given the importance of the legal consequences of this evaluation, it seems desirable that this practice is mastered by all practitioners. However, in practice there is often a disparity between forensic assessments and evaluations provided by other practitioners. To assess this difference in evaluation, we conducted a retrospective study, looking at 4 years of archives, of victims of Marseille's forensic service (CHU Timone), and highlighted a disparity between medical examiners, GPs and emergency physician's assessments. In both comparisons between medical examiners versus GPs (n = 367) or medical examiners versus emergency physicians (n = 511), were found in one third of cases of forensic requalification. The majority of checks on where GP's (80%) determined on over 8 days leave were reassessed under this limit by a medical examiner. This trend is reversed for the majority of (61%) requalification cases of emergency assessments (assessment over eight days by medical examiners. This study, proving a fact long suspected, raises many questions about these disparities evaluation we have discussed.     

Towards computational models of intention detection and intention prediction

Intention recognition is one of the core components of mindreading, an important process in social cognition. Human beings, from age of 18 months, have been shown to be able to extrapolate intentions from observed actions, even when the performer failed at achieving the goal. Existing accounts of intention recognition emphasize the use of an intent (plan) library, which is matched against observed actions for recognition. These therefore cannot account for recognition of failed sequences of actions, nor novel actions. In this paper, we begin to tackle these open questions by examining computational models for components of human intention recognition, which emphasize the ability of humans to detect and identify intentions in a sequence of observed actions, based solely on the rationality of movement (its efficiency). We provide a high-level overview of intention recognition as a whole, and then elaborate on two components of the model, which we believe to be at its core, namely, those of intention detection and intention prediction. By intention detection we mean the ability to discern whether a sequence of actions has any underlying intention at all, or whether it was performed in an arbitrary manner with no goal in mind. By intention prediction we mean the ability to extend an incomplete sequence of actions to its most likely intended goal. We evaluate the model, and these two components, in context of existing literature, and in a number of experiments with more than 140 human subjects. For intention detection, our model was able to attribute high levels of intention to those traces perceived by humans as intentional, and vice versa. For intention prediction as well, our model performed in a way that closely matched that of humans. The work highlights the intimate relationship between the ability to generate plans, and the ability to recognize intentions.     

“All I have to do is pass”: A discursive analysis of student athletes' talk about prioritising sport to the detriment of education to overcome stressors encountered in combining elite sport and tertiary education

ObjectivesIncreasingly, athletes are expected to undertake tertiary education contemporaneously with their sporting careers. However, to do so may prove difficult and stressful. Exploration of the stressors encountered by student-athletes in combining the two pursuits is limited. There is also limited research examining whether combining the two pursuits impacts upon sporting or educational success.Design and methodA discursive psychological approach was employed, examining twenty interviews conducted with Australian athletes enrolled in tertiary education, exploring how athletes integrated sport and education.ResultsWithin the interviews, athletes constructed their primary academic goal as to ‘just pass’. Athletes repeatedly presented themselves as sacrificing educational success to integrate the two pursuits. Moreover, athletes constructed accounts of themselves as prioritising sport, but as passive in decision-making around priorities. In doing so, athletes produced accounts that removed their own agency for their sacrificed academic success. The interviewees also constructed time as a barrier to the successful integration of sport and education. In the dataset time was constructed either as fixed, limited and externally controlled, or as flexible and controllable.ConclusionsThese alternate constructions allowed athletes to remove agency for poor educational outcomes, or conversely, enabled them to present themselves as successfully able to integrate sport and education. Thus, differing constructions of time were used to achieve different rhetorical ends. Implications and interventions for supporting student athletes successfully to combine sport and education are discussed.     

Effects of two types of career interventions on students with different career coping styles

Research on the efficacy of career interventions often lacks comparative analysis of the effects of different types of interventions. Additionally, little is known about the effects of interventions on diverse clients. Previous studies showed that students display different career coping styles and that these styles are relatively consistent across samples. The present study analyzes the effect of two types of career interventions (a single career information session and a six-week career intervention) on the career adaptability of students with different career coping styles. The study involved 319 students from grade 9 and grade 12 of three Portuguese public schools. Results show that although the interventions were effective for most of the students, the single informative session improved the career curiosity and confidence of only one group of students, whereas the six week career intervention revealed a more robust effect in students with insecure, pessimistic or superficial career coping styles. The theoretical and practical implications of the study are also discussed.
