The Difference

Abstract. An association between intelligence at age 7 and a set of five single-nucleotide polymorphisms (SNPs) has been identified and replicated. We used this composite SNP set to investigate whether the associations differ between boys and girls for general cognitive ability at ages 2, 3, 4, 7, 9, and 10 years. In a longitudinal community sample of British twins aged 2-10 (n > 4,000 individuals), we found that the SNP set is more strongly associated with intelligence in males than in females at ages 7, 9, and 10 and the difference is significant at 10. If this finding replicates in other studies, these results will constitute the first evidence of the same autosomal genes acting differently on intelligence in the two sexes.

AbstractAccumulating evidence suggests that dietary interventions might have potential to be used as a strategy to protect against age-related cognitive decline and neurodegeneration, as there are associations between some nutrients, food groups, dietary patterns, and some domains of cognition. In this study, we aimed to conduct the largest investigation of diet and cognition to date, through systematically examining the UK Biobank (UKB) data to find out whether dietary quality and food groups play a role on general cognitive ability. This cross-sectional population-based study involved 48,749 participants. UKB data on food frequency questionnaire and cognitive function were used. Also, healthy diet, partial fibre intake, and milk intake scores were calculated. Adjusted models included age, sex, and BMI. We observed associations between better general cognitive ability and higher intakes of fish, and unprocessed red meat; and moderate intakes of fibre, and milk. Surprisingly, we found that diet quality, vegetable intake, high and low fibre and milk intake were inversely associated with general cognitive ability. Our results suggest that fish and unprocessed red meat and/or nutrients that are found in fish and unprocessed red meat might be beneficial for general cognitive ability. However, results should be interpreted in caution as the same food groups may affect other domains of cognition or mental health differently. These discrepancies in the current state of evidence invites further research to examine domain-specific effects of dietary patterns/food groups on a wide range of cognitive and affective outcomes with a special focus on potential covariates that may have an impact on diet and cognition relationship.

Musical Excerpts

Brazilian listeners ( N = 303) were asked to identify emotions conveyed in 1-min instrumental excerpts from Wagner’s operas. Participants included musically untrained 7- to 10-year-olds and university students in music (musicians) or science (nonmusicians). After hearing each of eight different excerpts, listeners made a forced-choice judgment about which of eight emotions best matched the excerpt. The excerpts and emotions were chosen so that two were in each of four quadrants in two-dimensional space as defined by arousal and valence. Listeners of all ages performed at above-chance levels, which means that complex, unfamiliar musical materials from a different century and culture are nevertheless meaningful for young children. In fact, children performed similarly to adult nonmusicians. There was age-related improvement among children, however, and adult musicians performed best of all. As in previous research that used simpler musical excerpts, effects due to age and music training were due primarily to improvements in selecting the appropriate valence. That is, even 10-year-olds with no music training were as likely as adult musicians to match a high- or low-arousal excerpt with a high- or low-arousal emotion, respectively. Performance was independent of general cognitive ability as measured by academic achievement but correlated positively with basic pitch-perception skills.
