The irrelevant sound effect (ISE) typically refers to a disruptive effect of a to-be-ignored sound in serial recall tasks, where lists of visually presented items (digits and letters) must be recalled in serial order. Although extensively studied in adults, studies on developmental aspects of the ISE are scarce. The present study aims to increase our understanding of developmental changes of auditory distraction in children beyond serial recall. Two tasks (i.e., word categorization and evaluation of simple mathematical equations) were designed to test retrieval from semantic memory. Proportion correct and reaction times (adjusted for speed-accuracy tradeoff) were measured in 8-9 and 12-13-year-olds. Results revealed a developmental change in the susceptibility to auditory distraction. Whereas older children were not affected by background sounds, younger children showed impairment in both proportion correct and adjusted reaction times. Overall, results suggest that attention distraction and immature attention control mechanisms contribute to ISEs in young children.

This study examines the importance of saving during adolescence as one way of obtaining larger sums of money, and investigates differences between adolescents who choose to save and those who do not. To this end, the strategies “saving,” “negotiating,” “selling,” and “earning” are taken into account in designing a questionnaire. Two measures of saving behaviors are used: “general tendency to save” and “saving by adjusting expenditure” when faced with an income constraint. The sample consists of 470 British school students from age 11 to 18. Results show that up to age 15, the strategies “saving” and “negotiating” are equally important and more important than “selling” or “earning.” When 15 or older, adolescents prefer “saving” above “negotiating.” Regression analyses reveal that adolescents who favor “saving” when confronted with a short‐term income constraint report a general tendency to save. Findings demonstrate the importance of developing positive financial habits early in life.
