Abstract Study Objectives This study examines the cross-sectional and two-year follow-up relationships between sleep and stress and total hippocampal volume and hippocampal subfield volumes among older adults. Methods 417 adults (aged 68.8±7.3; 54% women) from the Irish Longitudinal Study on Ageing completed an interview, a questionnaire and multiparametric brain MRI. The relationships between self-reported sleep duration, sleep problems, perceived stress and total hippocampal volume were examined by using ordinary least squares regressions. Linear mixed-effects models were used to investigate the relationships between sleep duration, sleep problems, perceived stress, changes in these measures over two-years and hippocampal subfield volumes. Results No cross-sectional and follow-up associations between sleep and total hippocampal volume and between stress and total hippocampal volume were found. By contrast, Long sleep (≥9-10 hours / night) was associated with smaller volumes of molecular layer, hippocampal tail, presubiculum and subiculum. The co-occurrence of Short sleep (≤6 hours) and perceived stress was associated with smaller cornu ammonis 1, molecular layer, subiculum and tail. Sleep problems independently and in conjunction with higher stress, and increase in sleep problems over 2 years were associated with smaller volumes of these same subfields. Conclusion Our study highlights the importance of concurrently assessing sub-optimal sleep and stress for phenotyping individuals at risk of hippocampal subfield atrophy.

Preterm Children

The vocabulary size and composition of one group of full-term and three groups of low risk preterm children with different gestational ages (GA) were longitudinally compared at 10, 22 and 30 months of age. Expressive vocabulary development was assessed through the CDI. Cognitive development was also assessed at 22 months (Batelle Developmental Inventory), and data concerning biological and environmental characteristics of the children were also obtained. Growth curve analyses indicated that there were no significant differences in vocabulary size or percentage of word categories among GA groups. Regression analyses showed that word production and cognitive scores measured at 22 months were the main predictors of total vocabulary and word categories at 30 months. Gender, maternal education and GA did not contribute in a significant way to the variance of use of the vocabulary categories or vocabulary size. Therefore, GA does not seem to affect vocabulary development and composition when biomedical complications associated to prematurity are excluded.

Stage Change

Microprocesses of stage change were studied by applying Snyder and Feldman's consolidation/transition model to substages and subcontents of Selman's stages of friendship reasoning in a six-year longitudinal study of 97 9-to 15-year-old children. It was hypothesised that individuals exhibiting reasoning above their own modal stages would be more likely to experience a developmental advance in modal reasoning, even when examined at the level of substage and subcontent. This was confirmed; however, the amount of variance in above mode reasoning was not related to development. Finally, controversies in the prior literature were explained by methodological differences. It was concluded that the Piagetian processes underlying the Snyder and Feldman model were supported.
