Self‐esteem,stigma and community participation amongst people with learning difficulties living in the community

A cross‐sectional study examined the relationship between self‐esteem, community participation, age, perceived stigma and social support amongst a sample of 50 people with mild to moderate learning difficulties attending two day centres. Respondent‐paced, structured interviews following ethical and assessment guidelines were used to gather data. Retest interviews were conducted with 20% of the sample 3 months subsequently and only those measures with good test–retest reliability were used to test hypotheses. The results showed fairly high levels of community participation and self‐esteem. Self‐esteem was negatively correlated with stigma and a sub‐group with high concerns regarding meeting strangers was identified. In accordance with studies of non‐disabled samples, self‐esteem was positively associated with age. Social support was comparable to, or higher than, that observed in non‐disabled samples. High social support was observed for staff going out with respondents and for practical help from liked persons and friends. Community participation appeared to be related to higher self‐esteem in older participants but lower self‐esteem in younger participants. Implications for future research and practice are discussed.

Difficulties experienced by older drivers during their regular driving and their expectations towards Advanced Driving Aid Systems and vehicle automation

The aim of this study was to analyse the difficulties experienced by older drivers during their regular driving, and to identify their needs and their expectations regarding Advanced Driving Aid Systems (ADAS) and vehicle automation. More than 100 items were investigated by using a Focus Group method based on a Collective Questionnaire (named FoG-CoQS). Thirty elderly drivers, 15 females and 15 males aged from 70 to 81 years (mean age of 73.3; S.D. = 3.18) were recruited among a representative sample of 76 older drivers living in the Rhône area and having previously participated to an on-road experiment, in order to collect from this Focus Group method further information about the driving difficulties they experienced in their everyday life and their expectations towards driving aids. Seven main topics were more particularly investigated, recovering at last all the main dimensions of the driving task (from navigation to speed control, through intersection crossing).Regarding driving difficulties, one of the most interesting result collected is the high contrast between the literature review, identifying Left Turn (LT) manoeuvres at crossroads as a risky driving situation for elderly drivers, and the relatively low values of perceived difficulties (i.e. compared to other driving sub-tasks) collected during this Focus Group among our sample of older drivers. Regarding the driving aid functions investigated, 10 of them obtained high scores of “perceived utility” (i.e. overpassing 60% on scales ranging from 0% [no utility] to 100% [high utility]), and they concerned assistances liable to support all the main components of the driving task investigated in this study.Additional results are related to the differences between the elderly female and male drivers. Several driving situations were assessed as significantly more difficult to perform by the older female than by the older male drivers, like intersection crossing, entering expressways, or implementing a lane change manoeuver. By contrast, this gender effect is more limited regarding driving aids: synthetically, men and women have a positive attitude towards driving aid systems and their expectations for future ADAS are quite similar (for instance, “informative systems” are preferred than driving aids based on “vehicle automation”).Finally, from two transversal items (i.e. “difficulties” to perform a driving sub-task and “perceived utility” of ADAS), it was possible to rank older drivers’ difficulties experienced during their everyday life (from lowest difficulties to “navigate on a familiar itinerary” to highest when “interacting with bicyclists”) and their expectations towards driving aids (from lowest utility score given to “Automatic Lane Change systems” to highest utility value provided to “Speed Informer systems”). At last, older drivers’ acceptance and expectations towards highly automated cars was also investigated: full automation was assessed as an interesting solution to ensure the self-mobility of elderly peoples in their circle, but also for themselves in the future, in case of impairments of their own cognitive or physical capacities.     

The influence of motivational and emotional factors in mathematical learning in secondary education

IntroductionWhile motivation has, for decades, been investigated as a key component of academic learning and performance, academic emotions have often been left out of the scope of investigation. According to several researchers, mathematics learning seems to be particularly affected by students’ emotions.ObjectiveThis paper is aimed at characterizing the emotions and motivation of eighth grade students in a mathematical setting and highlighting the cluster of emotions–activity emotions vs outcome emotions–which best predict math value, math self-concept, behavioral engagement and math performance.MethodData were collected through questionnaires from 115 students and analyzed through means comparisons and linear regressions.ResultsResults indicated that eighth grade students give a relatively high value to mathematics have a positive mathematics self-concept and are moderately engaged in mathematical tasks. Regression analysis showed that mathematics value and behavioral engagement are better explained by activity emotions while mathematics self-concept and performance are better predicted by outcome emotions.ConclusionThe implications of these findings in terms of educational practices are discussed at the end of this study.     

A Challenge to Divine Psychologism

Alvin Plantinga proposes that mathematical objects and propositions are divine thoughts. This position, which I call divine psychologism, resonates with some remarks by contemporary thinkers. Plantinga claims several advantages for his position, and I add another: it helps to explain the glory of mathematics. But my main purpose is to issue a challenge to divine psychologism. I argue that it has an implausible consequence: it identifies an entity with God's relation to that entity. I consider and rebut several ways in which a divine psychologist might argue that this is not really a consequence, or that the identification is plausible.     

Potential traumatic events in early childhood and behavioural resilience: a longitudinal case control study

Abstract

Resilience can be evidenced when an exposure to potentially traumatic event (PTE) has no negative impact on behavior. This study explored the effects of exposure to PTE applying a longitudinal design with 592 children (mean age 4 years) followed across three years. Children who had experienced a PTE and those who had not, were compared over time. Behavioral difficulties and prosocial behaviour for children experiencing PTE did not differ from those who had not experienced a PTE suggesting resilience among the exposed children. PTE in itself seems to carry minimal risk for symptoms of behaviour difficulties among preschool children.     

Magnitude processing and complex calculation is negatively impacted by mathematics anxiety while retrieval‐based simple calculation is not

Mathematics anxiety (MA) refers to the experience of negative affect when engaging in mathematical activity. According to Ashcraft and Kirk (2001), MA selectively affects calculation with high working memory (WM) demand. On the other hand, Maloney, Ansari, and Fugelsang (2011) claim that MA affects all mathematical activities, including even the most basic ones such as magnitude comparison. The two theories make opposing predictions on the negative effect of MA on magnitude processing and simple calculation that make minimal demands on WM. We propose that MA has a selective impact on mathematical problem solving that likely involves processing of magnitude representations. Based on our hypothesis, MA will impinge upon magnitude processing even though it makes minimal demand on WM, but will spare retrieval‐based, simple calculation, because it does not require magnitude processing. Our hypothesis can reconcile opposing predictions on the negative effect of MA on magnitude processing and simple calculation. In the present study, we observed a negative relationship between MA and performance on magnitude comparison and calculation with high but not low WM demand. These results demonstrate that MA has an impact on a wide range of mathematical performance, which depends on one's sense of magnitude, but spares over‐practiced, retrieval‐based calculation.

听写困难儿童在笔画加工中的整体干扰效应

听写困难是指儿童阅读正常而听写落后的现象,是一种常见的儿童学习障碍类型。听写困难儿童的字形表征缺陷可能来源于局部字形加工中的整体干扰。分别从整体字形干扰和整体语音干扰两个角度来考察听写困难儿童在笔画加工中的整体干扰机制。整体字形干扰研究表明,笔画加工过程受到整体字形的干扰,这种干扰发生在所有儿童身上,但对听写困难儿童的干扰效应更为明显;整体语音干扰研究表明,在笔画加工过程中,正常儿童受到整体语音的显著干扰,而听写困难儿童并未受到整体语音的干扰。综合整体字形干扰和整体语音干扰的结果,提出听写困难儿童的整体字形加工能力缺陷假说和笔画的视觉加工模式假说,究竟哪一种假说更为合理,还有待进一步研究     

It pays to compare: An experimental study on computational estimation

Comparing and contrasting examples is a core cognitive process that supports learning in children and adults across a variety of topics. In this experimental study, we evaluated the benefits of supporting comparison in a classroom context for children learning about computational estimation. Fifth- and sixth-grade students (N = 157) learned about estimation either by comparing alternative solution strategies or by reflecting on the strategies one at a time. At posttest and retention test, students who compared were more flexible problem solvers on a variety of measures. Comparison also supported greater conceptual knowledge, but only for students who already knew some estimation strategies. These findings indicate that comparison is an effective learning and instructional practice in a domain with multiple acceptable answers.
