In perceptual learning, performance often improves within a short time if only one stimulus variant is presented, such as a line bisection stimulus with one outer-line-distance. However, performance stagnates if two bisection stimuli with two outer-line-distances are presented randomly interleaved. Recently, S. G. Kuai, J. Y. Zhang, S. A. Klein, D. M. Levi, and C. Yu, (2005) proposed that learning under roving conditions is impossible in general. Contrary to this proposition, we show here that perceptual learning with bisection stimuli under roving is possible with extensive training of 18000 trials. Despite this extensive training, the improvement of performance is still largely specific. Furthermore, this improvement of performance cannot be explained by an accommodation to stimulus uncertainty caused by roving.

Synaptic weight decay with selective consolidation enables fast learning without catastrophic forgetting (2019, background): “This is indeed a well known phenomenon in psychophysics, called roving (Tartaglia et al., 2009b; Parkosadze et al., 2008) or interleaved learning (Flesch et al., 2018).”

Perceptual learning, roving and the unsupervised bias. (2012, unknown): “…perceptual learning does not occur when certain stimulus types are combined during training, i.e. under so called roving conditions (Banai et al., 2009; Kuai et al., 2005; Otto et al., 2006; Parkosadze et al., 2008; Tartaglia, Aberg, & Herzog, 2009; Yu, Klein, & Levi, 2004; Zhang et al., 2008).”

Perceptual learning and roving: Stimulus types and overlapping neural populations. (2009, unknown): “Moreover, roving affected the learning process but not performance per se, i.e. baseline performance for a stimulus type in roved and non-roved condition was roughly comparable Parkosadze et al., 2008.”
