reaction

 [re-ak´shun]
1. opposite action or counteraction; the response of a part to stimulation.
2. the phenomena caused by the action of chemical agents; a chemical process in which one substance is transformed into another substance or substances.
3. in psychology, the mental or emotional state that develops in any particular situation.
4. the specific cellular effect produced by foreign matter, as in testing for allergies. For specific reactions, see under the name, such as pirquet's reaction.
reaction of degeneration the reaction to electrical stimulation of muscles whose nerves have degenerated, consisting of loss of response to a faradic stimulation in a muscle, and to galvanic and faradic stimulation in the nerve.
reaction time the time elapsing between the application of a stimulus and the resulting reaction.

reaction time 

The time interval between the onset of a stimulus and the response of a subject. Visual stimulations with a flash of light give rise to reaction times varying between 130 and 180 ms. This figure diminishes significantly with age.

Nevertheless, on the whole, the reversal of temporal and magnitude relations gave rise to similar levels of accuracy and response latency and the accuracy and response latency of temporal relational responding was similar to previous studies.
For all command types, response latency data were collected with the use of M Stopwatch, an iPhone application, and were calculated by converting all data from minutes and seconds to total seconds.
The response latency of Ft, Mt, St, and Ss GCs was the same as that in the S1 condition.
As compared to saline, MeOV at doses 15 and 30 mg/kg significantly elevated the response latency duration to a maximum rise of 20.33 2.75 s in hot plate test, while itincreased to a maximum of 18.333.38 s in tail immersion test as shown in figures 3 and 4 respectively.
We currently do not know how absence of one physiological ankle and the sensorimotor structures associated with the ankle affect the EMG response latency following SSRs in transtibial prosthesis users in the prosthetic and intact limbs.
Response Latency ([LAT.sub.n]): The time that passes (measured in milliseconds) during trial n from the start of the trial until a button is first pressed.
These limitations with the IRAP seem to emerge from the need to compare differences in response latency between blocks of consistent trials and blocks of inconsistent trials.
In addition, the program recorded data for each participant's overall average response latency for all North American males, Middle Eastern males, CVC stimuli, and arbitrary line stimuli, as well as individual latency averages for all stimuli.
However, scholars suggest response latency measures may be a more valid means of assessing implicit racial prejudice because research has shown that traditional racial prejudice measures are subject to social desirability responses, whereas response latency techniques are an indirect, unobtrusive measure of racial attitudes (Dovidio, Kawakami, Johnson, Johnson, & Howard, 1997).
Waveform dynamics of the ERGs in response to individual flashes of light were analyzed for (a) response latency, defined as the amount of time elapsed from the onset of the light stimulus until the onset of the photoreceptor response, and (b) time-to-peak, defined as the amount of time elapsed from the onset of the light stimulus until the peak response.
It was anticipated (hypothesis 1) that a participant's dysphoric status (dysphoric v non-dysphoric \ control) would influence response latency to cue words with controls being quicker to access AMs than dysphoric participants.
H2: On average, response latency will be shorter with increasing apparent dimensionality.
