Parental Personality,Relationship Stress,and Child Development: A Stress Generation Perspective

This study aimed to investigate associations among the parental personality dimensions of self‐criticism and dependency, parental relationship stress, and child development from a stress generation perspective. Data from 79 first‐time parents and their children aged 8–13 months, who were followed up in a two‐wave, 1‐year longitudinal study, were analysed within a multilevel structural equation modelling framework in order to account for within‐couple interdependence. Results revealed that, as hypothesised, both parental self‐criticism and dependency were associated with increased levels of relationship stress, which in turn were negatively related to child development. Hence, parental personality features in combination with relationship stress may be an important target in couple and family‐based interventions. Implications for further research on family dynamics and interventions are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Effects of problem presentation durations on arithmetic strategies: a study in young and older adults

Young and older adults were asked toaccomplish a computational estimation task (i.e. provide approximate sums to two-digit addition problems like 38 + 74) under a short versusa longer presentation duration condition. In a choice condition, participants selected the better strategy more often under a long than undera short presentation duration and after an easier than after a harder problem. In the no-choice condition, influence of presentation durationon strategy execution depended on the preceding problems, as participants showed sequence poorer strategy effects. That is, participantswere slower while executing the poorer than while executing the better strategy on current problems following better strategy problems (butequally fast after poorer strategy problems) only under short presentation duration condition. These findings have important theoreticalimplications, as current assumptions of computational models of strategies cannot explain how problem presentation durations influencestrategy selection and strategy execution.
