This work compared two common variants of a lexical decision task (LDT) through two different analysis procedures: first, the classical ANOVA method, and second, by fitting the data to an ex-Gaussian distribution function. Two groups of participants (old and young university students) had to perform, blocks of go/no-go and yes/no tasks. Reaction times and error rates were much lower in the go/no-go task than in the yes/no task. Changes in the ex-Gaussian parameter related to attention were found with word frequency but not with the type of LDT tasks. These findings suggest that word frequency shows an attentional cost that is independent of age. 相似文献

Despite the increase in the incidence and prevalence rates of children and adolescents' mental disorders, there are few works performed with large and representative samples of children and adolescents with psychopathological symptoms. The present work analyses 588 participants referred by first care pediatricians to a specialized unit for children and adolescents' mental health. As a result of the study, a statistically significant relation was found between age and diagnosis: a larger incidence of behavioral disorders, communication disorders, elimination disorders, pervasive developmental disorders, impulse-control disorders from 0 to 5 years; behavioral disorders and attention deficit hyperactivity disorder (ADHD) were more common from 6 to 11 years, behavioral and anxiety disorders were more likely at 12 to 15 years; and, lastly, behavioral disorders were more prevalent from 16 to 18 years. With respect to gender, there was a significant relationship with diagnosis: boys had more behavioral disorders, whereas girl had more anxiety disorders. To conclude, a relationship between mental disorders and developmental achievements could be indicated in the younger group. Additionally, externalizing disorders in boys and internalizing ones n girls were more prevalent across all ages. 相似文献
