Auditory Reaction Time

Latencies for phonation initiation (from adducted, abducted, and a subject method, prephonatory vocal-fold position) were studied in 30 young adults under an auditory reaction time paradigm as a function of random prestimulus intervals. Shortest latencies were obtained when the auditory stimulus was presented within a 1000- to 2000-millisecond flame. Stimulus delivery at intervals exceeding or preceding this time flame increases the latency of vocal reaction.

Somatosensory Stimuli

A missing stimulus task requires an immediate response to the omission of a regular recurrent stimulus. The task evokes a subclass of event-related potential known as omitted stimulus potential (OSP), which reflects some cognitive processes such as expectancy. The behavioral response to a missing stimulus is referred to as omitted stimulus reaction time (RT). This total RT measure is known to include cognitive and motor components. The cognitive component (premotor RT) is measured by the time from the missing stimulus until the onset of motor action. The motor RT component is measured by the time from the onset of muscle action until the completion of the response. Previous research showed that RT is faster to auditory than to visual stimuli, and that the premotor of RT to a missing auditory stimulus is correlated with the duration of an OSP. Although this observation suggests that similar cognitive processes might underlie these two measures, no research has tested this possibility. If similar cognitive processes are involved in the premotor RT and OSP duration, these two measures should be correlated in visual and somatosensory modalities, and the premotor RT to missing auditory stimuli should be fastest. This hypothesis was tested in 17 young male volunteers who performed a missing stimulus task, who were presented with trains of auditory, visual, and somatosensory stimuli and the OSP and RT measures were recorded. The results showed that premotor RT and OSP duration were consistently related, and that both measures were shorter with respect to auditory stimuli than to visual or somatosensory stimuli. This provides the first evidence that the premotor RT is related to an attribute of the OSP in all three sensory modalities.

The Relationship

Balance in children is one of the most important things to notice during its development. Increased risk of loss ofbalance is often associated with a slow reaction time. The purpose of this study was to determine the relationshipbetween auditory reaction time and body balance in students at Elementary School in Baha village. This research wasconducted in March 2018 with cross sectional analytic study design. Samples were taken by simple random samplingmethod with 96 samples. The sample age range is 8 - 10 years. The independent variable is auditory reaction timemeasured using computerized reaction time test software. Dependent variable is body balance measured usingPediatric Balance Scale. The relationship between two variables was analyze using Pearson Correlation test. There isa significant correlation between auditory reaction time to body balance, based on data output from analysis withsignificance <? (p = 0,006). Furthermore, based on data output known Correlation Coefficient of -0.228 which meansthe existence of negative and linear relationship. There was a significant relationship between auditory reaction timeand body balance in elementary school children in Baha Village.Keywords: Reaction Time, Auditory, Balance, Children

Interlingual Homographs

This chapter on the reading of words by multilinguals considers how retrieving words in two or more languages is affected by the lexical properties of the words, the sentence context in which they occur, and the language to which they belong. Reaction time and event-related potential (ERP) studies are discussed that investigate the processing of cognates, interlingual homographs, and words with different numbers of neighbors, both in isolation and in sentence context. After reviewing different models for multilingual word retrieval, it is concluded that multilingual word recognition involves a language-independent, context-sensitive, and interactive pattern recognition routine, with temporal properties that can be determined not only by “classical” reaction time techniques, but even better by up-to-date research techniques such as eye-tracking and ERP recordings.

Emotional Words

Objectives: Stuttering and phonological processing are mutually related. Emotion is an effective factor in fluency and language processing; however, its underlying neural mechanism remains unclear. Event-Related Potential (ERP) is a non-invasive highly-beneficial method with high time resolution for language processing. The present study aimed to explore phonological processing in emotional words in Children Who Stutter (CWS), compared to Typically-Developing Children (TDC). Methods: Ten Persian-speaking CWS (3 girls, 7 boys), aged 7-10 years (Mean±SD = 8.9±0.11) and 10 TDC who are matched in age (Mean±SD = 8.7±0.12) and gender were given 120 emotional words (high-valence low-valence) and neutral words to read. Phonological processing was measured by the aloud reading task, while ERP was simultaneously recorded. The collected results were analyzed as behavioral (reaction time and reading accuracy) and electrophysiological (amplitude and topography). Repeated-measures Analysis of Variance (ANOVA) and Independent Samples t-test were used for between-group comparisons. Results: The obtained behavioral data included Reaction Time (RT) and accuracy. There were no significant differences between the explored CWS and TDC in RT and accuracy (P>0.05). The mean value of amplitudes presented significant differences between CWS and TDC in language processing areas (P<0.05). The collected results indicated higher mean values of amplitude for neutral words. The distribution highly differed between the investigated CWS and TDC in neutral and negative words. However, there were similarities in positive words in distribution between the study groups. Discussion: The studied CWS and TDC were similar concerning behavioral results. High-valence words in the CWS group presented a higher similar distribution, compared to the TDC groups; however, low-valence words in the explored CWS had a more similar amplitude to the TDC group for neutral words. Then, emotional content facilitated phonological processing in the investigated CWS in the given time range.
