Comparing Judgments of Visual Clarity and Spatial Brightness through an Analysis of Studies Using the Category Rating Procedure
Steve Fotios,Deniz Atli +1 more
TL;DR: In this article, a review of the descriptions reported in past articles suggests that some researchers consider spatial brightness and visual clarity to be different, although this is not a universal opinion, and analyses of the results of brightness and clarity judgments given by naive test participants to lighting of different spectral power distribution in previous work suggests that similar judgments are given when the meanings of these items are undefined in the test procedure and this is the more frequent situation.

Lamp spectrum and spatial brightness at photopic levels: A basis for developing a metric
TL;DR: In this article, the spectral power distribution (SPD) of a light source is used to better match the sensitivity of visual perception, which may allow the same spatial brightness but at lower illuminance with potential reductions in energy consumption.

Lamp spectrum and spatial brightness at photopic levels: Investigating prediction using S/P ratio and gamut area
TL;DR: In this article, an experiment was carried out to investigate spatial brightness at photopic levels under lighting of different spectral power distributions, and it was concluded that while lighting of a higher S/P ratio was brighter, the S /P ratio alone was insufficient to predict spatial brightness.
Rating Spatial Brightness: Does The Number Of Response Categories Matter?

TL;DR: In this paper, a range of graphical and statistical methods of analysis were employed, with one approach being to ignore all ratings given to the neutral category in odd scales, and it was found that while the response distribution may have changed, the number of response categories did not affect the central tendency of opinion.

Comparing Judgements of Visual Clarity and Spatial Brightness

- 01 Apr 2012
TL;DR: In many studies evaluating the visual environment test participants are asked to make judgements of particular visual attributes such as brightness, clarity and pleasantness as mentioned in this paper, which may be a dubious assumption, in particular because in the majority of studies it appears that the nature of visual attributes was not well defined.
