The files raw_data_implicit.csv, raw_data_mean.csv, raw_data_variance.csv and raw_data_shape.csv contain data accompanying the preprint "Limits of perception and richness of behaviour: Dissociating implicit and explicit ensemble representations" by Sabrina Hansmann-Roth, Árni Kristjansson, David Whitney and Andrey Chetverikov. The folder R-code contains all files used to analyse the data and create the Figures in the result section of the preprint. Short data description from the paper: "Visual ensembles, like leaves on a tree, often share properties such as shape or color. This redundancy can be quantified as a feature probability distribution whose summary statistics (e.g., mean) observers can report explicitly. Here, we show that such explicit reports underestimate the richness of ensemble perception. Participants searched for an odd-one-out target among heterogeneous distractors and their memory of distractor characteristics was tested explicitly or implicitly. Our observers could explicitly distinguish distractor sets with different mean and variance, but not differently-shaped probability distributions. In contrast, implicit assessment revealed encoding of mean, variance, and importantly, also distribution shape. Furthermore, explicit measures had common noise sources that distinguished them from implicit measures. We conclude that feature distributions are encoded in rich detail and can guide behaviour, while explicit summary judgments are based on information equivalent to a few samples from fully encoded distributions."
