TL;DR: For instance, the authors found that sex differences in spatial abilities are found in species in which one sex or the other engages the physical world in more complex ways, such as having a larger home range.

TL;DR: In this paper , the authors tested the hypothesis that there are sex differences in the pathways to mathematical development and found that the spatial pathway to mathematical competence was relatively more important for boys and the in-class attention pathway for girls.
Abstract: The study tested the hypothesis that there are sex differences in the pathways to mathematical development. Three hundred forty-two adolescents (169 boys) were assessed in various mathematics areas from arithmetic fluency to algebra across 6th to 9th grade, inclusive, and completed a battery of working memory, spatial, and intelligence measures in middle school. Their middle school and 9th grade teachers reported on their in-class attentive behavior. There were no sex differences in overall mathematics performance, but boys had advantages on all spatial measures (ds = .29 to .58) and girls were more attentive in classroom settings (ds = -.28 to -.37). A series of structural equation models indicated that 6th- to 9th-grade mathematical competence was influenced by a combination of general cognitive ability, spatial abilities, and in-class attention. General cognitive ability was important for both sexes but the spatial pathway to mathematical competence was relatively more important for boys and the in-class attention pathway for girls.

TL;DR: In this paper , a step back in time to pre-modern societies and an examination of life in remaining traditional societies today reveals that universal formal schooling is an historically recent phenomenon, and that instructional practices modify evolved or biological primary abilities to create evolutionarily novel or biologically secondary academic competencies (e.g., reading).
Abstract: Schooling is ubiquitous in the modern world and academic development is now a critical aspect of preparation for adulthood. A step back in time to pre-modern societies and an examination of life in remaining traditional societies today reveals that universal formal schooling is an historically recent phenomenon. This evolutionary and historical recency has profound implications for understanding academic development, including how instructional practices modify evolved or biological primary abilities (e.g., spoken language) to create evolutionarily novel or biologically secondary academic competencies (e.g., reading). We propose the development of secondary abilities promotes the emergence of academic self-concepts that in turn are supported by evolved systems for self-awareness and self-knowledge. Unlike some forms of self-knowledge (e.g., relative physical abilities) that appear to be universal and central to many people’s overall self-concept, the relative importance of academic self-concepts are expected to be dependent on explicit social and cultural supports for their valuation. These culturally contingent self-concepts are contrasted with universal social and physical self-concepts, with implications for understanding variation students’ relative valuation of academic competencies and their motivations to engage in academic learning.

TL;DR: In this article , the authors provide state-of-the-art reviews of the brain and cognitive systems that are engaged during some aspects of mathematical learning, as well as the self-beliefs, anxiety and social factors that influence engagement with mathematics, along with discussion of any associated sex differences.

TL;DR: For instance, this paper found that the difference in performance between genders in algebra and word problems was mediated by spatial abilities and mathematics anxiety, controlling myriad confounds. But, there were no sex differences on the general algebra measure or for mathematics achievement.
Abstract: Adolescents' (n = 342, 169 boys) general algebra and algebra word problems performance were assessed in 9th grade as were intelligence, academic achievement, working memory, and spatial abilities in prior grades. The adolescents reported on their academic attitudes and anxiety and their teachers reported on their in-class attentive behavior in 7th to 9th grade. There were no sex differences on the general algebra measure or for mathematics achievement, but boys had an advantage on the algebra word problems measure (d = .51) and for spatial abilities (ds = .29 to .58). Boys had higher mathematics self-efficacy (d = .24 to .33), lower mathematics anxiety (ds = -.31 to -.53) and were less attentive in classrooms (ds = -.28 to -.37). A series of structural equation models revealed the sex difference for algebra word problems was mediated by spatial abilities and mathematics anxiety, controlling myriad confounds.

TL;DR: The authors investigated the role of working memory in symbolic and spatial algebra and related tasks across five experiments and found that both verbal and spatial working memory retention engage domain-general attention, but that their maintenance mechanisms differ.
Abstract: We investigated the role of working memory in symbolic and spatial algebra and related tasks across five experiments. Each experiment combined a processing task (expression evaluation, arithmetic, coordinate plane, geometry, or mental rotation) with verbal and spatial memory loads in a dual-task design. Spatial memory was compromised in the presence of more difficult processing tasks, and verbal memory was only compromised in the presence of algebraic tasks. The latter was related to the demands of retaining quantities associated with variables in verbal memory. We suggest that both verbal and spatial working memory retention engage domain-general attention, but that their maintenance mechanisms differ. Verbal memory has attention-based and rehearsal-based mechanisms, and thus sustaining verbal information over a short period is less attention-demanding than holding spatial information. We suggest that effects of a memory load on processing (e.g., x = 6) depend on whether use of maintenance strategies are possible for the specific memory load while carrying out processing. In all, our results indicate that algebraic tasks use domain-general attention and include verbal processing of algebraic variables (i.e., information conveyed in x, y). We discuss the implications for algebra learning and working memory theories. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
TL;DR: It is pointed out that contemporary evolutionary-developmental accounts address the shortcomings of mainstream evolutionary psychology they describe, while maintaining an adaptationist perspective that includes a central role of evolved, domain-specific information-processing mechanisms.
Abstract: Narvaez et al. (2022), in their article "Evolving Evolutionary Psychology," argue that mainstream evolutionary psychology is based on misguided neo-Darwinian adaptationist thinking and an antiquated computationalist, "mind-as-computer" framework and offer their own developmentally informed theory as an alternative. While applauding Narvaez et al. for promoting the role of development in evolutionary explication and as a potential metatheory for psychology, we point out that contemporary evolutionary-developmental accounts address the shortcomings of mainstream evolutionary psychology they describe, while maintaining an adaptationist perspective that includes a central role of evolved, domain-specific information-processing mechanisms.
