In particular, van Leeuwen and van den Hof (1991) and Kubovy and Wagemans (1995) measured information content of visual stimulus using Shannon's measure of information.
The authors hypothesized that (1) negative valence (unpleasant) stimuli and/or high arousal stimuli will lead to greater tinnitus loudness and annoyance than positive valence and/or low arousal stimuli, and (2) auditory emotional stimuli, which are in the same modality as the tinnitus, will exhibit a greater effect on tinnitus outcome measures than visual stimuli.
The time measured between the onset of the visual stimulus and a participant's movement from the home key was defined as reaction time (RT), and the time measured between a participant's lift from the home key and depression of the response key was defined as movement time (MT).
An additional point regarding the validity of non-symbolic number sense measures is that these measures are inherently confounded by visual stimulus parameters which may distort results (see Szűcs, Nobes, Devine, Gabriel & Gebuis, 2013b; Gebuis & Reynvoet, 2012; Clearfield & Mix, 1999; Mix et al., 1997).
Test trials were conducted after each conditioning session to measure neuronal responses to the conditioned visual stimulus.
Main Outcome Measure: Reaction time: latency between visual stimulus and verbal response.
Visual shifts are typically measured as changes of straight-ahead judgments of a visual stimulus after a period of prism adaptation, whereas proprioceptive shifts are measured as changes of straight-ahead pointing [29].
The Hooper Visual Organization Test (Hooper, 1983) measures an individual's ability to spatially organize visual stimulus parts.
The ease of use of the single digital measure to evaluate creativity of visual stimuli provides academics and students an initial assessment of the quality of content selected prior to subjective aesthetic judgment.
The first test was 30 sec in duration and measured simple reaction time as speed of motor response to a repeated unexpected visual stimulus.
