Heterogeneity in types of errors. a An example error (thick line) made to the rightward target when cued to the left (monkey M, session 2). This type of error can be characterized as an early plan that is not changed even after receiving a contradictory cue (type 1). Light traces indicate all correct trials with the same leftward cue. b An incorrect reach to the bottom target (monkey C, session 1). This type of error can be characterized as a late reversion to the initial plan (type 2). c An incorrect reach to the leftward target (monkey M, session 1). This error represents a late switch away from the correct reach plan (type 3). d Histogram showing the frequency of each error type for both monkeys (monkey C, black; monkey M, gray). Filled and open segments indicate whether the errors were made to a favored or non-favored target, respectively
