A multi-year evaluation of the effects of a Response to Intervention (RTI) model on identification of children for special education

The purpose of this study was to examine the effects of implementation of a systematic response to intervention (RTI) model on the identification and evaluation of children for special education. Using a multiple baseline design, a systematic model of assessment and intervention was introduced in consecutive years for all elementary schools (N = 5) in the district. Effect of the RTI model on number of evaluations conducted, percentage of evaluated children who qualified for services, and proportion of identified children by sex and ethnicity before and after implementation of the model was examined. Additionally, outcomes for children who did not have an adequate response to intervention versus those who were at-risk but responded successfully to short-term intervention were examined. A cost analysis of use of the model was provided. The degree to which data obtained were used by the decision-making team was also examined. The assessment and intervention procedures, decision rules, and schoolwide training methods are described in detail and practical implications are discussed.     

"What if…": The Use of Conceptual Simulations in Scientific Reasoning

The term conceptual simulation refers to a type of everyday reasoning strategy commonly called "what if" reasoning. It has been suggested in a number of contexts that this type of reasoning plays an important role in scientific discovery; however, little direct evidence exists to support this claim. This article proposes that conceptual simulation is likely to be used in situations of informational uncertainty, and may be used to help scientists resolve that uncertainty. We conducted two studies to investigate the relationship between conceptual simulation and informational uncertainty. Study 1 was an in vivo study of expert scientists; the results suggest that scientists do use conceptual simulation in situations of informational uncertainty, and that they use conceptual simulation to make inferences from their data using the analogical reasoning process of alignment by similarity detection. Study 2 experimentally manipulated experts' level of uncertainty and provides further support for the hypothesis that conceptual simulation is more likely to be used in situations of informational uncertainty. Finally, we discuss the relationship between conceptual simulation and other types of reasoning using qualitative mental models.

Situated problem solving in Kashmiri carpet weaving practice

This paper discusses situated problem solving accomplished in the three constituent domains of Kashmiri carpet weaving practice viz. designing, coding and weaving. While, the designers’ problem relates to carving spatial regions on graph-sheets, the coders’ problem relates to cognitively demarcating relevant coding area in those graphs while generating code. Likewise, the weavers’ problem lies in demarcating weaving-territory on the loom, while the manufacturers’ problem relates to determining a particular spatial area for quality assessment. The paper discusses how the actors create fixed, transient and negotiable boundaries on the graph, the loom and the carpet to solve this problem of area determination and demarcation.Section 1 introduces this practice, its task domains and the problem of area determination and demarcation, Section 2 discusses the methodology, Section 3 discusses in detail the problem of area-determination in each task domain and the problem solving strategies employed by the actors using material available in their task-environments itself. In addition, the problem and resolution of area determination as encountered by the manufacturers is discussed. The paper concludes with a discussion on findings of this study with larger findings in cognitive science and accentuates the role played by situated and distributed cognition in unearthing the findings reported in this paper.     

Resilience in elite sport and at work – A comparative analysis among German elite athletes and employees

ObjectiveThe first purpose was to examine and compare the different levels of resilience for elite athletes and employees. Second, we investigated the relationship between resilience and personality traits for both groups. Finally, we explored how resilience is linked to sporting success.DesignCross-sectional, self-report survey.MethodA total of 720 participants (mean age = 28.59, SD = 22.02, males = 51.7%, 256 elite athletes, 132 dual students, and 332 employees) were surveyed and completed scales about resilience, personality traits, and sporting success. Analysis of variance to identify mean level differences between groups and regression analysis to examine the effect of resilience on sporting success.Results and conclusionsThe group of athletes shows significantly higher levels of resilience than the groups of dual students and employees. We find positive relationships between resilience and all considered personality traits but find that the level of correlations varies. Resilience is rather a prerequisite for top-level sports participation than a predictor for sporting success.     

Dynamic locomotor imagery in athletes with severe visual impairments

Motor imagery is a mental process not accompanied by movement and widely studied in healthy subjects, related to hand movements in terms of timing. This study compared static and dynamic motor imagery analyzing temporal and spatial features in different locomotor conditions in three different groups of subjects: high-skilled athletes with visual impairments, a group of sighted unprofessional athletes and a control group of sighted subjects. We found that dynamic motor imagery resulted in timely closer to real performance than static motor imagery. The discrepancies between dynamic motor imagery and real condition, in fact, resulted limited to uncommon locomotion, such as lateral walking. Motor imagery resulted closer to real performance in terms of timing than in terms of step length, with the exception of athletes with visual impairments that, differently from the other groups, did not show any significant differences between the numbers of imagined and performed steps. It opens a new question about the relationship between temporal and spatial imagination of locomotion.     

Passion,grit and mindset of Iranian wrestlers: A socio-psychological approach

The study presents a socio-psychological analysis of the conventional psychological concept of passion, grit and mindset among Iranian elite wrestlers, along with exploring the associations of the aforementioned variables. We conducted a cross-sectional, correlational questionnaire survey among 124 international and national Iranian top male wrestlers and recruited 106 male and female Iranian university students as a control group to provide more rationale of the variables within the context. Passion Scale, Grit-S Scale and Theories of Intelligence Scale (TIS) were used to measure the variables. The wrestlers scored high on the passion, grit and growth mindset scales, higher than the controls. Further analysis indicated a positive association between passion, grit and growth mindset on wrestlers as a whole and the subgroups. There were, however, no differences in terms of the level of competency and achievement within the groups of wrestlers, which counters former findings. This research contributes valuable insights into how passion, grit and growth mindset, considering the interplay between individual agency and an apt social context, sustain athletes’ desire for tough training; motivate them to overcome a series of setbacks and challenging situations in order to meet further achievements in such a competitive sport. The research further provides insight into a distinctive sport culture and proposes how the socio-cultural context of athletes impacts their mentality and achievement.     

Perspectival representation and fallacies in metaethics

Abstract

The prevailing theoretical framework for theorising about representation construes all representation as involving objective representational contents. This classic framework has tended to drive philosophers either to claim that evaluative judgements are representations and therefore objective, or else to claim that evaluative judgements are not really representations, because they are not objective. However, a more general, already well-explored framework is available, which will allow theorists to treat evaluative judgements as full-fledged representations (thus doing justice to their representational aspects) while leaving open whether they are objective. Such a more general conception of representational content is exemplified, e.g. by Lewis’s ‘centred contents’ and Gibbard’s framework of ‘contents of judgement’, thus it is not new. I shall start in §1 by introducing the more general framework of perspectival contents and then illustrate in §2 how awareness of it can help expose the fallaciousness of certain widely used forms of argumentation in metaethics.     

Using another's gaze as an explicit aid to insight problem solving

Research has shown that implicitly guiding attention via visual cues or unrelated tasks can increase the likelihood of solving insight problems. We examined whether following another person making specific skin-crossing saccades could induce similar attentional shifts and increase solution rates for Duncker's ((1945) Duncker, K. 1945. On problem solving. Psychological Monographs, 58 (5, Whole No. 270)[Crossref] , [Google Scholar]) radiation problem. We presented 150 participants with one of three 30-s eye movement patterns from another problem solver: (a) focusing solely on the central tumour; (b) naturally making skin-crossing saccades between the outside area and the tumour from multiple angles; or (c) making deliberate skin-crossing saccades between the outside area and the tumour from multiple angles. Following another person making skin-crossing saccades increased the likelihood of solving the radiation problem. Our results demonstrate that another person's eye movements can promote attentional shifts that trigger insight problem solving.     

Biomechanical Motor Patterns in Normal Walking

Motor patterns in normal human gait are evident in several biomechanical and EMG analyses over the stride period. Some of these patterns are invariant over the stride period with changes of cadence, while others are closely correlated with speed changes. The findings for slow, natural, and fast walking are summarized: 1. Joint angle patterns over the stride period are quite invariant, and do not change with cadence;

2. Moment of force patterns at the ankle are least variable and quite consistent at all speeds;

3. A recently defined support moment is quite consistent at all speeds.

4. Moments at the knee and hip are highly variable at all cadences but decrease their variability as cadence increases;

5. Mechanical power patterns at all joints show consistent timing over the stride period;

6. EMG profiles of 5 muscles show consistent timing over the stride, but the amplitude increases as walking speed increases.

Arguments are presented to support the concept that walking speed is largely controlled by gain and that the timing of the motor patterns, which is extremely tightly synchronized with the anatomical position, is under major afferent control.
