Abstract
First paragraph: There is an error in the analysis pipeline for the greyscales (GRE) and gratingscales (GRA) tasks. This has led to all spatial bias scores (PSEs) for the greyscales and gratingscales tasks having inverted signs: all positive values (i.e. rightward biases) should be negative (i.e. leftward biases), and vice versa. The spatial bias values per se are not affected. All other tasks are unaffected and this does not change the main message of the article (i.e. significant intra-task correlations across 2 testing days, but no inter-task relationships between the 5 tasks). This single error in the processing pipeline has led to the following errors throughout the article: There is an error in the Methods section under the subheading “LM, GRE and GRA tasks.” The second sentence should read: Accuracy for each of the 17 stimulus asymmetries was converted into a percentage of trials where the subject perceived the stimulus to be either longer (LM) / darker (GRE) / have more “thin stripes” (GRA) on the right side of space. There are several errors in the Results section. The third sentence under the subheading “Summary of overall task bias” should read: There was a significant, weak leftward bias for the GRE task on Day 1 [t(49) = 2.098, p = 0.041] but not Day 2. The first sentence of the second paragraph under the subheading “Inter-task reliability” should read: Only the MLB and GRA tasks provided significant (yet weakly) correlated mean measures of bias at α = 0.05 that failed to maintain significance when the alpha was Bonferroni corrected for multiple comparisons (Pearson’s r = -0.287, p = 0.043, adjusted α = 0.005). The first sentence of the second paragraph under the subheading “Principal component analysis (PCA)” should read: There were strongly positive loadings for the GRA and MLB tasks on the first principal component (PC1). There are several errors in the Discussion section. The fourth sentence of the first paragraph should read: A mean leftward bias was found in the GRE task on the first day of testing, whereas there was no mean lateralised bias when participants were re-tested. The second sentence under the subheading “Inter-task correlations” should read: Although the MLB and GRA tasks proved to hold the closest correlation between measures of asymmetry relative to the other 3 tasks (r = -0.287, p = 0.043) this did not survive multiple comparison correction.
