Using the single-outcome gambling task, this study investigated

age-related and sex-related differences between the FRN in middle and late adolescents and adults. Forty healthy adolescents (15-17 years old) and 28 healthy adults (20-25 years old) were recruited in the event-related potentials study. The electrophysiological selleck kinase inhibitor response to gains and losses of low and high magnitude were recorded during the single-outcome gambling task. The FRN significantly delayed in middle and late adolescents compared with adults (232.875 vs. 211.714 ms). Adults are more sensitive to the magnitude of feedback (larger amounts: 50 cents vs. small amounts: 10 cents) than valence (gain: +50/10 vs. loss: -50/10). However, middle and late adolescents are neither sensitive to magnitude nor to valence. Men showed significantly more negative FRN amplitude than women both in adolescents and adults. In addition, the hostility Acalabrutinib chemical structure subscore of the Buss-Perry Aggression Questionnaire was negatively correlated with FRN amplitude. The results of this study suggested that the age-related differences did exist between the FRN in adolescents and those in adults. Men require more neural activity than women to achieve similar feedback both in adolescents and adults.

“Impairments on neuropsychological and eye

movement tasks have been demonstrated in schizophrenic patients and also reported in their unaffected relatives. However, it is not clear to what extent these phenotypes overlap. This study examined the relationship between specific eye movement and neuropsychological measures. The relationship between performance on eye movement and neuropsychological tasks was

measured in 79 schizophrenic patients (63% from Multiply affected families), 129 of their healthy first-degree relatives, and 72 normal controls. Antisaccade scores were correlated with most measures of neurocognitive functioning, and this correlation was strongest in schizophrenic patients in all cases. In the schizophrenic patients, but not their relatives or controls, AR-13324 the antisaccade distractibility error (ADE) score correlated significantly with current intelligence, verbal memory (immediate and delayed recall), and associative learning. In the case of crystallised IQ and delayed verbal memory, smaller correlations were present in unaffected relatives. although neither survived Bonferroni correction. Smooth pursuit performance was unrelated to any neuropsychological measure. Our study Suggests that antisaccade errors are likely to represent part of a generalized neuropsychological deficit in schizophrenia. (C) 2008 Elsevier Ireland Ltd. All rights reserved.”
