The study of auditory and visual reaction times in chronic smokers

چکیده
Audio-visual reaction time is a reliable indicator to assess the processing capability of central nervous system and sensory motor performance in response to an external stimulus. The present study was aimed to find out whether chronic smoking affects the processing capability of central nervous system. The audiovisual reaction times of 120 male subjects with age ranging from 25 to 55 years forming various groups as control and smoker were measured by a device “Response Analyzer”. The auditory reaction time was recorded for high frequency sound and visual reaction time for red light. The observations revealed that both auditory and visual reaction times were significantly delayed in chronic smokers as compared to that in controls. The results indicated that alteration of the processing capability of central nervous system as reflected by the changes in auditory and visual reaction times might be due to impaired perceptual-motor coordination in chronic smokers.

Comparison of the Effect of Visual and Auditory Distractions on the Physiological Parameters during the Dressing Change Procedure in 6-12-Year-Old Children
Background and Objective: As pain impulses ascend from the spinal cord, the autonomic nervous system is stimulated and leads to changes in physiological parameters. This study aimed to compare the effect of visual and auditory distractions on the physiological parameters during dressing change procedure in children aged 6-12 years. Materials and Methods: This blinded clinical trial was conduct...
متن کاملSelective deficits in human audition: evidence from lesion studies
The human auditory cortex is the gateway to the most powerful and complex communication systems and yet relatively little is known about its functional organization as compared to the visual system. Several lines of evidence, predominantly from recent studies, indicate that sound recognition and sound localization are processed in two at least partially independent networks. Evidence from human...

Since there are variations in the reaction times of athletes in different sports, the aim of the present study was to evaluate the effectiveness of a specific training program on a simple reaction time of male gymnasts. In this longitudinal study, fourteen adolescent gymnasts (mean age 12.6 ± 2.1 years) were randomly selected to work out for 15 months in the artistic group. Simple reaction ti...
