Since contrast sensitivity (CS) relies on the accuracy of stimulus presentation, the reliability of the psychophysical procedure and observer's attention, the measurement of the CS-function is critical and therefore, a useful threshold contrast measurement was developed. The Tuebingen Contrast Sensitivity Test (TueCST) includes an adaptive staircase procedure and a 16-bit gray-level resolution. In order to validate the CS measurements with the TueCST, measurements were compared with existing tests by inter-test repeatability, testretest reliability and time. The novel design enables an accurate presentation of the spatial frequency and higher precision, inter-test repeatability and test-retest reliability compared to other existing tests. 429-441 (1946). 4.

“…83 In successive evaluations, observers have to retain their sensory impression of the preceding stimulus in mind while waiting for and then judging the current stimulus. 92 Thus, a possible explanation of interval bias is memory limitation: The observer either cannot or does not record an accurate sensory intensity in the first stimulus when making comparison with the second stimulus. 83 Mental representations of previously encountered physical stimuli tend to be lower (e.g.…”

Light sources are available in a variety of spectral power distributions (SPDs) and this affects spatial brightness in a manner not predicted by quantities such as illuminance. Tuning light source SPD to better match the sensitivity of visual perception may allow the same spatial brightness but at lower illuminance with potential reductions in energy consumption. Consideration of experimental design was used to review 70 studies of spatial brightness. Of these, the 19 studies considered to provide credible evidence of SPD effects were used to explore metrics for predicting the effect of SPD but did not provide conclusive evidence of a suitable metric, in part because of incomplete reporting of SPD characteristics. For future work, these data provide an independent database for validating proposed metrics.

“…It is common to see pronounced response biases in designs with more than one alternative to choose from (Jäkel & Wichmann, 2006) (Jäkel & Wichmann, 2006). In our task this could have been due to the fact that observers reported their perceptual decision using both hands on the Optimal experimental design for MAPS 22 keyboard, and that their handedness could have interacted with response frequency.…”

Perceptual bias is inherent to all our senses, particularly in the form of visual illusions and aftereffects. However, many experiments measuring perceptual biases may be susceptible to non-perceptual factors, such as response bias and decision criteria. Here we quantify how robust Multiple Alternative Perceptual Search (MAPS) is for disentangling estimates of perceptual biases from these confounding factors. First our results show that while there are considerable response biases in our four-alternative forced choice design, these are unrelated to perceptual biases estimates, and these response biases are not produced by the response modality (keyboard versus mouse). We also show that perceptual bias estimates are reduced when feedback is given on each trial, likely due to feedback enabling observers to partially (and actively) correct for perceptual biases. However, this does not impact the reliability with which MAPS detects the presence of perceptual biases.Finally, our results show that MAPS can detect actual perceptual biases and is not a decisional bias towards choosing the target in the middle of the candidate stimulus distribution. In summary, researchers conducting a MAPS experiment should use a constant reference stimulus, but consider varying the mean of the candidate distribution. Ideally, they should not employ trial-wise feedback if the magnitude of perceptual biases is of interest.
