“…For these subjects, visual inspection confirmed that none of the 5 exemplar SFT models were supported. It is possible that these data reflect some mixture of serial and parallel processing (see e.g., Little, Eidels, Houpt, Garrett, & Griffiths, 2018;Tillman & Evans, 2019), or a hybrid stopping rulehowever there is no available diagnostic for such phenomena at this time.…”

It has long been known that cues can be used to improve performance on memory recall tasks. There is evidence to suggest additional cues provide further benefit, presumably by narrowing the search space. Problems that require integration of two or more cues, alternately referred to as memory intersections or multiply constrained memory problems, could be approached using several strategies, namely serial or parallel consideration of cues. The type of strategy implicated is essential information for the development of theories of memory, yet evidence to date has been inconclusive. Using a novel application of the powerful Systems Factorial Technology (Townsend & Nozawa, 1995) we find strong evidence that participants use two cues in parallel in free recall tasks -a finding that contradicts two recent publications in this area. We then provide evidence from a related recognition task showing that while most participants also use a parallel strategy in that paradigm, a reliable subset of participants used a serial strategy. Our findings suggest a theoretically meaningful distinction between participants strategies in recall and recognition based intersection memory tasks, and also highlight the importance of tightly controlled methodological and analytic frameworks to overcome issues of serial/parallel model mimicry.

“…It is not clear why some subjects in Experiment 2 did not exhibit any of the canonical SFT model signatures. It is possible that these subjects utilized some hybrid or mixture of processes, which can be difficult to diagnose (Little et al, 2018;Tillman & Evans, 2019).…”

“…For the conjunctive category, values of both dimensions are combined orthogonally to create stimuli for which these decisions are either easy on both dimensions, difficult on both dimensions, or easy on one dimension but difficult on the other. By performing contrasts of the mean RTs (and the distributions), one can differentiate whether the stimulus dimensions are combined in serial, in which case the interaction will be additive, in parallel, in which case the interaction will be underadditive, or coactive and pooled into a single decision, in which case the interaction will be overadditive (Algom et al, 2015;Altieri et al, 2017;Little et al, 2019Little et al, , 2022Townsend & Nozawa, 1995). Hence, both dimensions of the stimulus are relevant and selective attention cannot be used to filter out either dimension unlike in the present task.…”

In the study of perceptual categorization, a key distinction is made between separable and integral dimensions. Separable dimensions are easy to attend in isolation, while integral dimensions are not. Little et al. (2016) showed that when trial-by-trial responses are analyzed, a consistent pattern of sequential effects was found in a modified Garner paradigm using integral-dimension stimuli. The present experiments investigated whether these pronounced sequential effects are also found with separable-dimension stimuli. Four experiments using two different types of separable dimensions were conducted. The results indicated that similar patterns of sequential effects were present for separable-dimension stimuli, but, unlike for integral dimensions, the effect of a change in the irrelevant dimension in the filtering task was not found. Further, for separable dimensions, the overall pattern of sequential effects did not vary between the Garner tasks (i.e., control, correlated, and filtering). To explain these results, we fit a sequence-sensitive exemplar model and compared the fits of this model to a novel sequence-sensitive feature model, in which only the relevant feature influences the categorization decision. We found that the full exemplar model provided a more compelling account of both our separable dimension data and the integral dimension data of Little et al. (2016). These findings provide a more complete understanding of perceptual categorization and add to the growing body of literature on the prevalence and critical implications of strong sequential effects in cognitive tasks.
