1. The effect of noise on the amplitude and morphology of cortical auditory evoked potentials
Abstract Objective: To analyze the effect of noise on electrophysiological measurements (P1-N1-P2 complex) of cortical auditory evoked potentials in normal hearing individuals of different ages. Methods: The inclusion criteria for the study were young individuals, adults and elderly, aged 18–75 years, with auditory thresholds up to 25 dB. Participants we

2. Efeito da idade no processamento auditivo temporal: benefício da modulação do mascaramento e efeito do pós-mascaramento
RESUMO Objetivo Investigar o efeito da idade no benefício da modulação do ruído mascarante (masking release) e no pós-mascaramento ( forward masking). Métodos Participaram da pesquisa jovens (média de idade de 18 anos e quatro meses) e idosos (média de idade de 64 anos e três meses) falantes nativos do Português Brasileiro e com audição norma

3. Inhibitory effect of a visual prime stimulus in simple reaction time task. / Efeito inibidor de um estímulo precedente visual em uma tarefa de tempo de reação simples.
Studies about attention orienting that use Posner?s procedure have demonstrated two effects: an initial facilitation of responsivit when the target stimulus appears in the same location as the prime stimulus and a subsequent inhibition of this responsvity. In a previous work we could not find the early facilitatory effect of attention orienting in a simple r

4. Control of attention by a peripheral visual cue depends on whether the target is difficult to discriminate
The influence of a peripheral cue represented by a gray ring on responsivity to a subsequent target varies. When a vertical line inside a ring was a go target and a white small ring inside a ring was a no-go target, reaction time was shorter at the same location relative to a different location. However, no reaction time difference between the two locations

5. Visual information processing after severe closed head injury: effects of forward and backward masking.
Three tachistoscopic tasks were employed to assess whether survivors of severe closed head injury (CHI) exhibit a disturbance of information processing within peripheral and/or central visual pathways. Twelve survivors of severe CHI and 12 individually matched control subjects completed a recognition threshold (no mask) task, a monoptic, forward masking by v

6. On- and Off-Frequency Forward Masking by Schroeder-Phase Complexes
Forward masking by harmonic tone complexes was measured for on- and off-frequency maskers as a function of masker phase curvature for two masker durations (30 and 200 ms). For the lowest signal frequency (1 kHz), the results matched predictions based on the expected interactions between the phase curvature and amplitude compression of peripheral auditory f
