Binocular pattern reversal evoked potentials (PREPs) and EEG power were recorded bilaterally from occipital scalp of 50 boys and 50 girls aged 5-14. PREP latency was unaffected by either age or gender. Amplitudes, however, were consistently larger for girls than boys, with differences diminishing by adolescence. Significant electrophysiological asymmetries(More)
Because the trier of fact determines the weight to be assigned to an examiner's opinion by assessing the strength and persuasiveness of his or her analysis of the data, it is essential that forensic reports communicate the examiner's reasoning process. This study analyzes community examiners' reports on competence to stand trial (CST), emphasizing the(More)
Three intensities of patterned and unpatterned flashes were used to elicit occipital visually evoked potentials (VEPs) from 4 groups of 15 subjects: boys and girls aged 7-9 years and boys and 15 girls aged 13-15 years. Interstimulus intervals (ISIs) of 1, 2 and 4 sec were used. Amplitude/intensity (A/I) slope was computed for each ISI and flash type(More)
Administered a modified Stroop Color-Word Test to 80 healthy males aged 21-90 years as part of a study of neuropsychological functioning. No age differences were demonstrated on simple reading tasks; however, significant age effects were observed for the color naming and interference tasks (ps less than .001). Ss in the oldest age groups (61-70 and 71-90(More)
Power spectral analysis and cortical coupling were computed on eyes closed EEG recorded from 80 normal volunteers: 20 females and 20 males aged 25-35 years and 20 females and 20 males aged 55-70 years. Recordings were from Fz, Cz, C3, Pz and Oz areas. The results indicate that with increased age there was a greater uniformity of EEG activity across the(More)
Electrophysiological age and sex differences in visual pattern responsivity were investigated. Pattern reversal evoked potentials (PREPs) and visual evoked potentials (VEPs) to patterned and unpatterned flashes were recorded from 20 normal subjects in each of 4 groups: young females and males aged 25-35 years and older females and males aged 55-70 years.(More)
