Speech and Language Disorders in Kenyan Children: Adapting Tools for Regions with Few Assessment Resources

This study sought to adapt a battery of Western speech and language assessment tools to a rural Kenyan setting. The tool was developed for children whose first language was KiGiryama, a Bantu language. A total of 539 Kenyan children (males=271, females=268, ethnicity=100% Kigiryama) were recruited. Data were initially collected from 52 children (pilot assessments), and then from a larger group of 487 children (152 cerebral malaria, 156 severe malaria and seizures, 179 unexposed). The language assessments were based upon the Content, Form and Use (C/F/U) model. The assessment was based upon the adapted versions of the Peabody Picture Vocabulary Test, Test for the Reception of Grammar, Renfrew Action Picture Test, Pragmatics Profile of Everyday Communication Skills in Children, Test of Word Finding and language specific tests of lexical semantics, higher level language. Preliminary measures of construct validity suggested that the theoretical assumptions behind the construction of the assessments were appropriate and re-test and inter-rater reliability scores were acceptable. These findings illustrate the potential to adapt Western speech and language assessments in other languages and settings, particularly those in which there is a paucity of standardised tools.     

Knowledge‐How and Cognitive Achievement

According to reductive intellectualism, knowledge‐how just is a kind of propositional knowledge (e.g., Stanley & Williamson 2001; Stanley 2011a, 2011b; Brogaard, 2008a, 2008b, 2009, 2011, 2009, 2011). This proposal has proved controversial because knowledge‐how and propositional knowledge do not seem to share the same epistemic properties, particularly with regard to epistemic luck. Here we aim to move the argument forward by offering a positive account of knowledge‐how. In particular, we propose a new kind of anti‐intellectualism. Unlike neo‐Rylean anti‐intellectualist views, according to which the possession of knowledge‐how is just a matter of possessing certain abilities, we submit that knowledge‐how is a particular kind of cognitive achievement attained just when cognitive ability is connected in the right way with successful performance.     

Knowledge‐How and Epistemic Luck

Reductive intellectualists (e.g., Stanley & Williamson 2001; Stanley 2011a; 2011b; Brogaard 2008b; 2009; 2011) hold that knowledge‐how is a kind of knowledge‐that. For this thesis to hold water, it is obviously important that knowledge‐how and knowledge‐that have the same epistemic properties. In particular, knowledge‐how ought to be compatible with epistemic luck to the same extent as knowledge‐that. It is argued, contra reductive intellectualism, that knowledge‐how is compatible with a species of epistemic luck which is not compatible with knowledge‐that, and thus it is claimed that knowledge‐how and knowledge‐that come apart.     

Exploring the Relationship Between Mathematics Anxiety and Performance: An Eye‐Tracking Approach

The mechanisms underpinning the relationship between math anxiety and arithmetic performance are not fully understood. This study used an eye‐tracking approach to measure a range of eye movements of 78 undergraduate students in response to performance on an arithmetic verification task. Results demonstrated a significant positive relationship between self‐reported math anxiety and response time, indicating reduced processing efficiency. Analysis of eye‐movement data reinforced the utility of an eye‐tracking approach in studying arithmetic performance; specific digit fixations, dwell time, saccades, and regressions all significantly predicted response time. Furthermore, findings highlighted significant positive correlations between math anxiety and fixations, dwell time, and saccades. Despite there being little evidence that eye movements mediate the math anxiety‐to‐performance relationship, relationships observed between math anxiety and eye movements provide a useful starting point for research using an eye‐tracking methodology in studying math anxiety and performance; the present findings suggest future work should focus on calculation strategy.

A Person‐oriented Approach to Identifying Parenting Styles in Mothers of Early School‐age Children

A substantial body of work has been dedicated to understanding the behaviours that characterize mothers' interactions with their children. Most research on parenting has used a variable‐oriented approach, limiting analysis to one or a few parenting behaviours and failing to identify higher‐order interactions or patterns among variables. Thus, little is known about how different behaviours co‐occur in individual mothers to form styles of parenting. In this study, a person‐oriented approach was used to develop a typology of maternal parenting styles based on a broad range of observed and self‐reported parenting behaviours. The study sample consisted of 408 socio‐demographically diverse mother–child pairs. Cluster analysis revealed six parenting groups—(1) balanced parenting; (2) warm/involved parenting; (3) task‐focused parenting; (4) detached/inconsistent parenting; (5) intrusive parenting; and (6) self‐critical parenting—two of which (task‐focused and self‐critical parenting) have not been previously represented in the parenting literature. The maternal parenting typology developed through this study provides useful information on the profiles of parenting behaviour that are associated with the highest levels of demographic and psychological risk in mothers who exhibit these profiles.

VARIETIES OF EXTERNALISM

Our aim is to provide a topography of the relevant philosophical terrain with regard to the possible ways in which knowledge can be conceived of as extended. We begin by charting the different types of internalist and externalist proposals within epistemology, and we critically examine the different formulations of the epistemic internalism/externalism debate they lead to. Next, we turn to the internalism/externalism distinction within philosophy of mind and cognitive science. In light of the above dividing lines, we then examine first the extent to which content externalism is compatible with epistemic externalism; second, whether active externalism entails epistemic externalism; and third whether there are varieties of epistemic externalism that are better suited to accommodate active externalism. Finally, we examine whether the combination of epistemic and cognitive externalism is necessary for epistemology and we comment on the potential ramifications of this move for social epistemology and philosophy of science.     

Can music lessons increase the performance of preschool children in IQ tests?

The impact of music on human cognition has a distinguished history as a research topic in psychology. The focus of the present study was on investigating the effects of music instruction on the cognitive development of preschool children. From a sample of 154 preschool children of Tehran kindergartens, 60 children aged between 5 and 6 were randomly assigned to two groups, one receiving music lessons and the other (matched for sex, age and mother’s educational level) not taking part in any music classes. Children were tested before the start of the course of music lessons and at its end with 4 subtests of the Tehran-Stanford-Binet Intelligence Scale (TSB). The experimental group participated in twelve 75-min weekly music lessons. Statistical analysis showed significant IQ increase in participants receiving music lessons, specifically on the TSB verbal reasoning and short-term memory subtests. The numerical and visual/abstract reasoning abilities did not differ for the two groups after lessons. These data support studies that found similar skills enhancements in preschool children, despite vast differences in the setting in which the instruction occurred. These findings appear to be consistent with some neuroimaging and neurological observations which are discussed in the paper.
