Controls for the multiple association learning assay. The simultaneous conditioning experiment shows that rovers (forR), sitters (fors) and sitter mutants (fors2) were able to perform similarly in single and double conditioning trials. The memory scores do not differ even when flies were required to learn more information in the double conditioning. Error bars represent ±s.e.m. (n = 20 for each bar; black bars, single training; white bars, double training).
