Raw data of visual search parameters of individuals with normal trichromacy and colour vision deficiency

Background: Colour-related search tasks are common in many professional fields. The study investigated whether increasing chromatic saturation can enhance the visual performance of individuals with colour vision deficiency (CVD) in colour-related search tasks.
Methods: 10 normal trichromats (5M, 5F; Mean (SD) age: 23.1 (3.3) years) and 15 individuals with CVD [8 deutans and 7 protans identified by HRR plates] (14M, 1F; aged 28.6 (8.7) years) participated in this study. Four naturalistic sceneries of everyday tasks/ birds, animals, and flowers of 15 different colour combinations (1 pair of colours in each combination. e.g., ‘brown/black’ or ‘red/green’) were presented in ‘low’ saturation, ‘original’ (unaltered images) and ‘high’ saturation condition using the Psychopy program on a colour-calibrated monitor. On each trial, the subject was asked to identify a specific-coloured target.
Results: Overall, the visual search performance index (expressed as product of accuracy and a reciprocal ..., The data is collected is based on a visual search task. The participants are required to perform a visual search task which involves identifying targets of varying difficulty in sceneries. The time taken for the correct response and accuracy is calculated, which is used towards the calculation of performance index (product of speed and accuracy)., , # Raw\_datasheet\_CVD\_search.xlsx

### Description of the data and file structure

There are two sheets in the Excel sheet. One sheet contains the data obtained for each of the CVD followed by sheet obtained for normal trichromats.

The three key terms are obtained for each colour combinations in each of the three saturation conditions (low, original and high) are accuracy, reaction time and performance index.

Performance index is a measure that summarises both reaction time and accuracy.

The colour combinations are arranged in alphabetical order.

The type of defect is also marked separately in a column. Out of 15 subjects with CVD, 8 had deutan deficiency and whereas 7 had protan deficiency

Sd column represents the standard deviation of the reaction time.

Figures 4 to 6 can be derived using the data provided in this excel sheet.
