Effect of light color temperature on selective attention, error rate and reaction time
Investigating the effect of light color temperature on selective attention, error and human reaction time Abstract Background and aims: In humans, the reaction time limit is associated with several factors. It includes the time that takes to stimulate the sensory member, the stimulus effect is transmitted to the brain, then is perceived and the decision is made; consequently, the command resu...
متن کاملAttention Span (sec) Figure 9. Response Time as a Function of Attention Span for Metricom Attention Span (sec) Figure 10. Response Time as a Function of Attention Span for the Wavelan Nis
An important issue to be addressed for the next generation of wirelessly-connected hand-held devices is battery longevity. In this paper we examine this issue from the point of view of the Network Interface (NI). In particular, we measure the power usage of two PDAs, the Apple Newton Messagepad and Sony Magic Link, and four NIs, the Metricom Ricochet Wireless Modem, the AT&T Wavelan operating a...
متن کاملBackward masking and the central performance drop
Kehrer [Spatial Vision 2 (1987) 247] found that texture discrimination performance sometimes peaks in the parafovea rather than at the fovea, and he referred to this phenomenon as the central performance drop (CPD). Kehrer used a backward mask to limit performance and Morikawa [Vision Res. 40 (2000) 3517] argued that in some cases the temporal aspects of the backward mask may be critical to the...
متن کاملSpatial processing and visual backward masking
Most theories of visual masking focus prima-rily on the temporal aspects of visual information processing, strongly neglecting spatial factors. In recent years, however, we have shown that this position is not tenable. Spatial aspects cannot be neglected in metacontrast, pattern and un-masking. Here, we review these results.
متن کاملFrequency discrimination in forward and backward masking.
Frequency difference limens for pure tones preceded by a forward masker or followed by a backward masker were obtained across a wide range of signal levels. Relkin and Doucet [Hear. Res. 55, 215-222 (1991)] have shown that at a masker-signal delay of 100 ms, the thresholds of high-SR (spontaneous rate) auditory-nerve fibers are recovered, while the low-SR fiber thresholds are not. Therefore, fo...
