Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Data on performance of 18 human subjects that searched for images of medium sized Tetrix subulata grasshoppers presented in sequences (10 images in each sequence) on computer screens against photographs of natural grasshopper habitat. The subjects were presented with three size-invariable sequences each (one for each of the black, grey and striped grasshopper colour morphs). The file includes information on background image identity, grasshopper colour morph, grasshopper image number, response time (time until response, either detection of grasshopper or incorrect response) and response (detection of grasshopper or incorrect response). Data for each sequence is included on a separate sheet.
