Participants who engaged in oral self-affirmation techniques demonstrated a ten-point IQ increase and were more likely to seek aid services.
A study by Harvard researchers found no effect of music training on the cognitive abilities of young children. Despite popular belief, studying music does not enhance intelligence or improve academic performance. However, the study did find some small differences in spatial task performance between music and visual arts groups.
