1 A highly complex drug made up of a whole series of chemicals with different reaction times , designed to fire particular synapses in the brain itself — to create , if you like , a false landscape of experience .
2 A similar conclusion emerges from a study by Caplan ( 1972 ) using another reaction time technique in which subjects had to decide whether a target word presented after a two-clause sentence had occurred in that sentence .
3 One month later the two groups had similar reaction times .
4 A. Simple reaction time When a light is switched on ( or a note is sounded ) a button must be pressed as quickly as possible ; the delay in doing this is measured .
5 The consequences for the performance of simple tasks was that simple and choice reaction times were worse at night than during the day , and that as days on the night shift went by , simple reaction time tasks became slower .
6 One group of Italian workers attempted to deal with the problem of ensuring equivalent left and right hemisphere damage in their two groups of patients by assessing simple reaction time to a visually presented stimulus .
7 A problem with this manoeuvre , however , is that certain evidence implicates the right hemisphere in control of simple reaction time ( Benson and Barton , 1970 ; Howes and Boller , 1975 ; Nakamura and Taniguchi , 1977 ) and thus equivalent response times for left and right hemisphere groups may not in fact reflect equivalent damage at the two sides of the brain .
8 Simple reaction time refers to a response , such as a key press , indicating merely that the stimulus has been detected , whereas discriminative reaction time refers to a response where some kind of discrimination is called for between two stimuli presented either simultaneously or successively .
9 On recruitment to the first study 92 healthy subjects rated their mood and performed various tasks ( a variable fore period simple reaction time task , five choice serial response task , repeated numbers detection task , free recall test , delayed recognition memory test , logical reasoning test , focused attention task , and categoric search task ) that have been described previously .
10 On recruitment to the second study 86 subjects , some of whom had symptomatic infections , rated their mood and performed 10 minute versions of the simple reaction time task and serial response task .
11 In the first study four of the 26 subjects with symptomatic infections had influenza B and showed a 38% increase in the mean time taken for the variable fore period simple reaction time task , from 320 ( SD 24 ) ms when recruited to 440 ( SD 90 ) ms when symptomatic .
12 The subjects with influenza B showed a 19% increase in the reaction time for the 10 minute version of the variable fore period simple reaction time test when compared with the controls ( symptomatic value 440 ( SD 82 ) ms , control value 369 ( SD 79 ) ms , p<0.05 ) .
13 Influenza B impaired performance of the simple reaction time task by about 20–40% , which is comparable to the 5–10% deterioration seen with alcohol consumption or work at night .
14 He hoped to achieve this by superimposing these mental activities upon the simple reaction time , SRT , and then subtracting the known value of the SRT from the total reaction time to give the duration of this mental activity .
15 Through this , it was also possible to calculate the the time taken for the simple reaction time involved in the relay of messages between the brain and the hand .
16 Simple reaction time is a fraction of the time required to react even when having to choose between only two possibilities .
17 Also , by separating the simple reaction time we see that reaction time increases steadily as the amount of discrimination required increases .
18 He hoped to achieve this by superimposing these mental activities upon the simple reaction time , SRT , and then subtracting the known value of the SRT from the total reaction time to give the duration of this mental activity .
19 The reaction product was visualised using a substrate solution containing 0.05% 3,3-diaminobenzidinetetrahydrochloride ( DAB ) ( Serva , Heidelberg , Germany ) , 0.01% hydrogen peroxide , 0.01% nickel chloride , and 0.01% cobalt chloride in TRIS buffered saline ( pH 7.6 ) with a usual reaction time of 10 minutes under microscopic examination .
20 It is hypothesised that words processed at deeper levels will be better recognised than those processed to only a shallow level and that reaction times will be longer at deeper levels of processing .
21 In the whole , as the degree of discrimination increased it was found that reaction time increased at a fairly constant rate .
22 It also hypothesises that reaction time increases as the size of a set from which an object must be identified increases .
23 Conversely , the constant reaction time found with left visual field presentations has been taken to imply that the right hemisphere processes information simultaneously , that is in parallel .
24 Although my elder two sons are experts in Streetcleaner Two , Sonic the Warthog and Attack of the Psychopathic Hippopotami , they live in Glasgow , where fast reaction times and knowledge of weird mutant creatures is necessary for survival on the no-mean-city streets , where the drivers are worse than the megabytten monsters .
25 We report the results of two studies to determine whether natural influenza B similarly prolongs human reaction times and whether other performance indicators are affected .
26 His stance should be relaxed , not fixed , since an unspecialized stance provides mobility and avoids the waste of valuable reaction time involved in switching to the best stance with which to meet an oncoming attack .
27 And so we will try and reestablish and reaffirm the main basic principles to make sure that you maintain proper safety margins and er good reaction time , room to manoeuvre , as we 're going through .
28 Scoring : A the end of the 50 experimental trials , all reaction times were crossed out the response sheet for incorrect answers , excluding them from further analysis .
29 Nor can it explain the shift from an initial RVF superiority on a visual reaction time task to a LVF superiority when a concurrent memory list of nouns is superimposed on the perceptual task ( Hellige , Cox and Litvac , 1979 ) .
30 Taken together with the finding that an initial RVF superiority on a visual reaction time task gave way to a LVF superiority when subjects were required to simultaneously hold in memory a list of nouns ( Hellige , Cox and Litvac , 1979 ) , this implies that dynamic shifts in attention are insufficient to explain all perceptual laterality effects .
