These files contain the data analysed and reported in the journal article **Carragher, D. J., Lawrence, B. J., Thomas, N. A., & Nicholls, M. E. R. (2018). Visuospatial asymmetries do not modulate the cheerleader effect**, published in *Scientific Reports*. If you have any further questions about the data contained in the spreadsheets, please send me an email: daniel.carragher@flinders.edu.au Experiment 1 The analysed cheerleader effect data is included in the columns 'LVF_Distractors_CE', 'BL_Distractors_CE' and 'RVF_Distractors_CE'. These columns show the cheerleader effect measure that has been calculated for each distractor condition, for each participant. Importantly, these values are change scores that were created by subtracting the attractiveness rating for each target image seen alone from the rating given to the same image seen among a group. Positive values indicate that the faces were rated to be more attractive in a group. Negative values indicate that the faces were rated to be more attractive alone. Experiment 2 The analysed data is included in the columns 'LVF_Target_CE', 'Centre_Target_CE' and 'RVF_Target_CE'. These columns show the cheerleader effect measure that has been calculated for each target condition, for each participant. Importantly, these values are change scores that were created by subtracting the attractiveness rating for each target image seen alone from the rating given to the same image seen among a group. Positive values indicate that the faces were rated to be more attractive in a group. Negative values indicate that the faces were rated to be more attractive alone. Exclusions The spreadsheet includes data from all tested participants. In order to replicate the results reported in the article, several participants must be excluded from analysis in both experiments. Participants are to be excluded if a '1' appears in the 'Exclusion' column. The final column in each spreadsheet contains a written reason for each exclusion. Mixed- and Left-handed participants were excluded from final analysis. Handedness was determined using the FLANDERS handedness questionnaire. Scores on the FLANDERS range from -10 (strongly left-handed) to +10 (strongly right-handed). Scores of -10 to +5 were criteria for exclusion. The column labelled 'Line Click Accuracy' shows the average vertical deviation that the participant made when making their response on the visual analogue scale. The value represents the average deviation from the visual analogue scale as a percentage of total screen size. We nominally elected to exclude participants with deviations greater than 2%, as we could not guarantee that the participant had completed the task carefully. In the published article, these are the participants 'who did not complete the task as instructed'. Finally, data was excluded if it fell further than 3SD from the condition mean. Importantly, these calculations occurred once data from participants excluded for Handedness and Line Click Accuracy had already been excluded from the dataset. All data from a participant was excluded from all analysis if a single cheerleader effect score fell further than 3SD from any one condition mean.
