Math anxiety: A review of its cognitive consequences,psychophysiological correlates,and brain bases

A decade has passed since the last published review of math anxiety, which was carried out by Ashcraft and Ridley (2005). Given the considerable interest aroused by this topic in recent years and the growing number of publications related to it, the present article aims to provide a full and updated review of the field, ranging from the initial studies of the impact of math anxiety on numerical cognition, to the latest research exploring its electrophysiological correlates and brain bases from a cognitive neuroscience perspective. Finally, this review describes the factors and mechanisms that have been claimed to play a role in the origins and/or maintenance of math anxiety, and it examines in detail the main explanations proposed to account for the negative effects of math anxiety on performance: competition for working memory resources, a deficit in a low-level numerical representation, and inhibition/attentional control deficit.     

Do Pro-environmental Behaviors and Awareness Contribute to Improve Subjective Well-being?

In this paper, we study the influence of both environmental awareness and behaviors on subjective well-being (SWB). By using ordered logit techniques in a sample from Granada, a city in southern Spain, we find that concern about the environment and voluntary work actions to preserve it are relevant for SWB. When both are combined, namely when a person is concerned and volunteers, the influence on SWB is greater. These results introduce the SWB dimension in the knowledge-concern-action paradox, which states that even if the individual is concerned about the environment, this concern does not always translate into personal action to preserve it. Actions such as habits related to water saving inside the household are not significant in explaining SWB, but using devices that save water increases it. In summary, our results suggest that actions and awareness have either a positive or no significant influence on SWB, but never a negative influence.

具身道德隐喻映射机制的双向性及其问题——基于具身效应“可重复性危机”的思考

具身认知研究虽已取得令人瞩目的进展,但某些具身效应存在可重复性较低的问题。若长期忽视这一问题,将严重损害心理学的科学性,甚至引发一定程度的“可重复性危机”。本文从道德概念清洁隐喻的两大映射方向出发,基于两大实验类型对相关研究中可能存在的问题因素分别展开分析。未来研究应关注更注重社会互动的组织道德,将道德概念具身隐喻研究引申到现实问题中,并借助认知神经科学技术更全面地考察身体经验、情绪体验和认知加工在道德清洁隐喻加工中的作用。     

The cognitive underpinnings of emerging mathematical skills: Executive functioning,patterns, numeracy,and arithmetic

Background: Exposure to mathematical pattern tasks is often deemed important for developing children's algebraic thinking skills. Yet, there is a dearth of evidence on the cognitive underpinnings of pattern tasks and how early competencies on these tasks are related to later development. Aims: We examined the domain‐specific and domain‐general determinants of performances on pattern tasks by using (a) a standardized test of numerical and arithmetic proficiency and (b) measures of executive functioning, respectively. Sample: Participants were 163 6‐year‐olds enrolled in primary schools that typically serve families from low to middle socioeconomic backgrounds. Method: Children were administered a battery of executive functioning (inhibitory, switching, updating), numerical and arithmetic proficiency (the Numerical Operations task from the Wechsler Individual Achievement Test‐II), and three types of pattern tasks. Results: Contrary to findings from the adult literature, we found all the executive functioning measures coalesced into two factors: updating and an inhibition/switch factor. Only the updating factor predicted performances on the pattern tasks. Although performance on the pattern tasks were correlated with numerical and arithmetic proficiency, findings from structural equation modelling showed that there were no direct or independent relationships between them. Conclusions: The findings suggest that the bivariate relationships between pattern, numeracy, and arithmetic tasks are likely due to their shared demands on updating resources. Unlike older children, these findings suggest that for 6‐year‐olds, better numerical and arithmetic proficiency, without accompanying advantages in updating capacities, will no more likely lead to better performance on the pattern tasks.     

Spanish adaptation of a perceived Social Support Scale in sportspeople

Social support is a variable that has a great influence in the sport context. In fact, this variable not only affects the athlete's performance but it has also shown to be related to psychological disorders such as Burnout Syndrome. The aim of this paper was to illustrate the Spanish adaptation of a social support scale in the sport context. The normative group who took part in the final version of the research was composed of 397 athletes aged between 13 and 64 years old (mean= 19.23 and standard deviation= 6.67). The scale shows: adequate factorial and construct validity, acceptable fit indexes (Kaiser-Meyer-Olkin= 0.785, Root Mean Square Residual= 0.078; Kelly's criterion= 0.075), a negative correlation with the dimensions of burnout and no relationship with respect to self-esteem. In addition, it also shows high reliability (a= 0.88). Furthermore, statistically significant differences have been found in relation to genders - where women require greater social support. In contrast, males tend to display a lower level of social support with team players and international athletes. Moreover, differential item functioning (DIF) was carried out to explore sex bias, however, none of the items exhibit DIF problems.     

The relationship between blushing propensity, social anxiety and facial blood flow during embarrassment

To investigate blushing in relation to blushing propensity scores and core elements of social anxiety, facial blood flow was monitored in 86 normal volunteers during an embarrassing task (singing a children's song). Increases in facial blood flow were greater in women than men, as were scores on the Blushing Propensity and Fear of Negative Evaluation scales. In addition, high scores on the Blushing Propensity and Social Interaction Anxiety scales were associated with large increases in facial blood flow during singing. However, this appeared to be due primarily to social anxiety because the association between blushing propensity scores and changes in facial blood flow disappeared when social interaction anxiety scores were taken into account. These findings suggest that people generally base their beliefs about blushing on cues other than changes in facial blood flow. Social anxiety may augment increases in facial blood flow during embarrassment, independently of expected or perceived blushing.     

Experimental determination of trapping efficiency of optical tweezers

We report an experimental determination of trapping efficiency of optical fields acting on spherical particles diluted in viscous fluids. This parameter was derived from experimentally calculated trap stiffness for micron-sized silica beads with particle radii of 1.5 and 4.8 microns, respectively. In order to obtain the trap stiffness, we used the equipartition theorem, and introduced an experimental procedure to calibrate the optical tweezers set-up. The method consists of the calculation of the trapping efficiency by using the curves of the trap stiffness vs. the incident power. Using this approach we measured the efficiency for different values of displacements of the beads in the optical trap, and compared these results with numerical and theoretical calculations reported in the literature, and an excellent agreement was found. We have shown that the ratio of efficiencies is very close to the ratio of the particle radii.
