25. Comparison of Pre-Attentive Auditory Discrimination at Gross and Fine Difference between Auditory Stimuli
Abstract Introduction Mismatch Negativity is a negative component of the event-related potential (ERP) elicited by any discriminable changes in auditory stimulation. Objective The present study aimed to assess pre-attentive auditory discrimination skill with fine and gross difference between auditory stimuli. Method Seventeen normal hearing individual

26. Temporal Resolution and Active Auditory Discrimination Skill in Vocal Musicians
Abstract Introduction Enhanced auditory perception in musicians is likely to result from auditory perceptual learning during several years of training and practice. Many studies have focused on biological processing of auditory stimuli among musicians. However, there is a lack of literature on temporal resolution and active auditory discrimination skills i

27. Brainstem Encoding of Aided Speech in Hearing Aid Users with Cochlear Dead Region(s)
Abstract Introduction Neural encoding of speech begins with the analysis of the signal as a whole broken down into its sinusoidal components in the cochlea, which has to be conserved up to the higher auditory centers. Some of these components target the dead regions of the cochlea causing little or no excitation. Measuring aided speechevoked auditory brain

28. Auditory Evoked Potentials with Different Speech Stimuli: a Comparison and Standardization of Values
Abstract Introduction Long Latency Auditory Evoked Potentials (LLAEP) with speech sounds has been the subject of research, as these stimuli would be ideal to check individualś detection and discrimination. Objective The objective of this study is to compare and describe the values of latency and amplitude of cortical potentials for speech stimuli in adu

29. Comparison of different speech tasks among adults who stutter and adults who do not stutter
OBJECTIVES: In this study, we compared the performance of both fluent speakers and people who stutter in three different speaking situations: monologue speech, oral reading and choral reading. This study follows the assumption that the neuromotor control of speech can be influenced by external auditory stimuli in both speakers who stutter and speakers who d

30. Long Latency Auditory Evoked Potential in Term and Premature Infants
Introduction The research in long latency auditory evokes potentials (LLAEP) in newborns is recent because of the cortical structure maturation, but studies note that these potentials may be evidenced at this age and could be considered as indicators of cognitive development. Purpose To research the exogenous potentials in term and premature infants

31. Modulation of spatial attention to visual targets by emotional environmental sounds
Previous research has shown that visual spatial attention can be modulated by emotional prosody cues, but it is not known whether such crossmodal modulation of visual attention is associated with the engagement or disengagement of attentional resources. To test this, we employed a modified spatial cueing task, where participants indicated whether a visual ta

32. An experiment set-up for analysis of lateralization judgments of binaural stimuli
INTRODUCTION: The aim of this work is to present a physical implementation of a noninvasive methodology to analyze the directional sensitivity of human auditory system. A computer controlled experiment set-up has been designed and developed to study the behavior of human subjects under the presentation of interaural time delays and interaural amplitude diffe

33. Temperament: an event-related potential study using the oddball paradigm
The present study examined the structure of interrelations between brain event-related potentials and behavioral measures and temperament dimensions during an attention task. Three temperament questionnaires were used: Eysenck Personality Inventory, Strelau Temperament Inventory, and Rusalov Structure of Temperament Questionnaire. Event-related potentials we

34. Controle ativo acústico estrutural: projeto, simulação e análise de qualidade sonora / Active structural acoustic control: design, simulation and analysis of sound quality
This master thesis deals with the study of active noise and sound quality control systems in automotive applications, and the innovative assessment of their performance based on relevant psychoacoustic metrics in this area such as Loudness, Roughness and Tonality. A methodology for designing and implementing active control systems based on psychoacoustic met

35. Estímulos CE-chirp e narrow band CE-chirps na avaliação eletrofisiológica da audição: resultados clínicos em neonatos, lactentes e crianças / CE-chirp and narrow band CE-chirps stimuli in electrophysiological assessment of hearing: clinical outcomes in neonates, infants and children
Os Potencias Evocados Auditivos de Estado Estável (PEAEE) têm sido apontados como uma alternativa aos Potenciais Evocados Auditivos de Tronco Encefálico (PEATE) para estimar os limiares auditivos em crianças que não conseguem realizar a avaliação auditiva comportamental com procedimentos condicionados. O objetivo deste estudo foi verificar a aplicabil

36. Correspondência fazer-dizer : variáveis de controle e condições de manutenção e generalização / Doing-saying correspondence: controlling variables and maintenance and generalization conditions.
The present proposal is based on the assumption that verbal responding is an operant behavior established and maintained by reinforcement contingencies. Study 1 evaluated the effects of three different correspondence training methods on the maintenance of eleven childrens accurate self-report. Doing consisted of reading aloud a written word presented on a co
