Beh'al = ratings that came from the initial behavioural landmark characterisation study. Correlations are shown between: mean salience scores from the initial characterisation study, the actual size and permanence of landmarks in Fog World, and ratings of permanence, salience and size from the fMRI subjects post-fMRI scan. Each cell shows the Pearson correlation r value above the corresponding p value. Significant correlations are highlighted in bold text.
*
Correlation is significant at the 0.05 level (2-tailed).
†
Correlation is significant at the 0.01 level (2-tailed).
