Caffeine has often been studied in connection with reaction time. I hope this review helps you write a good report on your reaction time experiment. Kroll found no effect of purely muscular fatigue on reaction time. Three times simple auditory reaction time was taken, and out of them fastest response was used for this study. However, the reaction time advantage of the preferred over the non-preferred hands was so small that they recommended alternating hands when using a mouse.
Perceptual and Motor Skills 95 3: Brebner and Welford report that reaction times are faster when the subject has been warned that a stimulus will arrive soon. The Journals of Gerontology, Series A 57 8: They are age,[ 4 ] sex,[ 4 , 5 ] gender,[ 4 , 6 ] handedness,[ 7 , 8 ] physical fitness,[ 9 , 10 ] sleep,[ 9 ] fatigue,[ 9 ] distraction,[ 9 , 11 ] alcohol,[ 12 ] caffeine,[ 13 ] diabetes,[ 14 ] personality type and whether the stimulus is auditory or visual. The effect of caffeine consumption on reaction time. Reaction time is fastest with an intermediate level of arousal, and deteriorates when the subject is either too relaxed or too tense Welford, ; Broadbent, ; Freeman, It was as if the isometric contraction allowed the brain to work faster.
Bertelson found that as long as the warning was longer than about 0. Formulate and test hypotheses regarding reaction times.
Personal tempo and phenomenal time at different age levels. Electroencephalography and Clinical Neurophysiology 5: In a surprising finding, Szinnai et al.

In this review, I have ignored these brain organization questions and summarized the major literature conclusions that are applicable to undergraduate laboratories using my Reaction Time software. In this study, there is statistically no significant difference in reaction time between congenital blind and normal healthy persons with a different kind of sound such as horn, bell, ring, and whistle in their group.
Pushing the liherature of task difficulty for the right and left hands in manual aiming. Subjects were explained and demonstrated about the procedure to be performed. Compensating loterature alcohol-induced impairment: Attentional dynamics in postural control during perturbations in young and older adults.
Index finger of the dominant hand of participant was used on the liteerature to get a response. Minor upper respiratory tract infections slow reaction time, make mood more negative, and cause disturbance of sleep Smith et al. Older age, traumatic brain injury, and cognitive slowing: Kashihara and Nakahara found that vigorous exercise did improve choice reaction time, but only for the first 8 minutes after exercise.
Work of the integrated organism. Van den Berg J, Neely G. They are age,[ 4 ] hime 45 ] gender,[ 46 ] handedness,[ 78 ] physical fitness,[ 910 ] sleep,[ 9 ] fatigue,[ 9 ] distraction,[ 911 ] ,iterature 12 ] caffeine,[ 13 ] diabetes,[ 14 ] personality type and whether the stimulus is auditory or visual. Study had been carried reviea in two groups: Welford and Broadbent reviewed studies showing that distractions increase reaction time. The lab tested the reaction time on Biology students at Inver Hills Community College, and the effect and choice, where the subject gives a response that corresponds to the stimulus Kosinski, A Literature Review on Reaction Time.
Procedures done before obtaining simple reaction time The detailed information of study to participants and informed written consent was taken before staring the reaction time.
The time course of preparation. Simple auditory reaction time response with four different type of sound was recorded in both groups. Hy effect of caffeine consumption on reaction time. Monte BuchsbaumEnoch Callaway Perceptual and motor skills The preferred hand was generally faster.
The present study was undertaken on the sample size containing 50 blind subject and 50 healthy control subjects with applying necessary inclusion and exclusion criteria as mentioned earlier.
Motivation and Emotion 28 2: Other Factors Influencing Reaction Time. In other words, the relationship is: There are multiple stimuli and multiple responses. Lenzenweger found that the reaction times of schizophrenics was slower than those of normal people, but their error rates were the same.
An example very much like our experiment was reported by Surwilloin which reaction was faster when a single tone sounded than when either a high or a low tone sounded and the subject was supposed to react only when the high tone sounded.
