Fig. 1.

(a) The figure provides a schematic depiction of the employed experimental paradigm used. Within a block design (each epoch 27 s), the task alternated between Memory Encoding, Rest/Rehearsal and Cued Retrieval. During Memory Encoding, nine objects (3s/object, 9 objects total) were presented in random sequence in their associated grid location for naming. An instruction free fixation interval followed. During cued Retrieval, grid locations were cued and participants were asked to recall (by naming) the object associated with the location. A total of eight epochs of each type were employed in sequence to maximize the chances of participants reaching asymptotic performance. (b) Averaged behavioral performance across the eight epochs is depicted (# correct) with a relational Gompertz function fitted to the mean performance curve of all 19 subjects (dashed line). As the shaded windows indicate, performance could be differentiated into early epochs (linearly increasing performance regime) and late epochs (asymptotic performance regime).
