“…Within the multiple-component model, it is proposed that working memory consists of multiple resources, many of which are domain-specific. A distinction is made specifically between resources supporting verbal memory and resources supporting visuospatial memory (Baddeley, 1986; Baddeley & Logie, 1999; Baddeley et al, 2019; Berry et al, 2019; Shah & Miyake, 1996). The model proposes two entirely separate subsystems for holding verbal and visuospatial information, the phonological loop and the visuospatial sketchpad, respectively.…”

An ongoing major debate centers around whether multi-tasking in working memory, that is, performing several mental activities at once, is supported by multiple specialized domain-specific or by a single-purpose domain-general cognitive resources. Working memory theories differ in their explanations and predictions about when performing two mental tasks causes performance failures, versus when two processes can be carried out concurrently with negligible cognitive costs. In particular, the predictions of domain-specific and domain-general views on working memory are in conflict with one another when it comes to the cognitive cost associated with concurrent verbal and visuospatial processing and storage tasks. Previous tests of these predictions using traditional methods have led to ambiguous and inconsistent conclusions, however. To make critical progress in this theoretical debate, we used a radically different approach combining Bayesian state-trace analysis with an experimental design fully crossing processing and storage tasks differing only in the domain of representation (verbal vs. visuo-spatial).Across two experiments, we show unambiguously that a single, domain-general factor can account for briefly maintaining verbal and visuo-spatial information in a multitasking scenario.

“…The first two experiments examined recall accuracy in two different continuous response tasks implemented under conditions of simultaneous encoding of multi‐item arrays. Experiment 1 used a color–orientation task adapted from Berry et al (2019). In this task, participants are presented with an array of colored bars of varying orientations, followed by a test probe, with the task being to align the orientation of this bar with that seen during the encoding phase, based on its color.…”

“…For Experiment 1, the orientation recall task was adapted from that employed in Berry et al (Berry et al, 2019), with the task written in Psy-choPy 1.84 (Peirce, 2007). Participants were presented with 4-item arrays of colored bars each measuring 2 Â 0.3 of visual angle (1.75 cm Â 0.25 cm) at different orientations (see Figure 1a).…”

Debate continues regarding the possible role of the hippocampus across short-term and working memory tasks. The current study examined the possibility of a hippocampal contribution to precise, high-resolution cognition and conjunctive memory.We administered visual working memory tasks featuring a continuous response component to a well-established developmental amnesic patient with relatively selective bilateral hippocampal damage (Jon) and healthy controls. The patient was able to produce highly accurate response judgments regarding conjunctions of color and orientation or color and location, using simultaneous or sequential presentation of stimuli, with no evidence of any impairment in working memory binding, categorical accuracy, or continuous precision. These findings indicate that hippocampal damage does not necessarily lead to deficits in high-resolution cognitive performance, even when the damage is severe and bilateral.

Visual short-term memory (vSTM) is often measured via continuous-report tasks whereby participants are presented with stimuli that vary along a continuous dimension (e.g., colour) with the goal of memorising the stimuli features. At test, participants are probed to recall the feature value of one of the memoranda in a continuous manner (e.g., by clicking on a colour wheel). The angular deviation between the participant response and the true feature value provides an estimate of recall---and hence, vSTM---precision. Two prominent models of performance on such tasks are the two- and three-component mixture models (Bays et al., 2009; Zhang & Luck, 2008). Both models decompose participant responses into probabilistic mixtures of: (1) responses to the true target value based on a noisy memory representation; (2) random guessing when memory fails. In addition, the three-component model proposes (3) responses to a non-target feature value (i.e., binding errors). Here we report the development of mixtur, an open-source package written for the statistical programming language R that facilitates the fitting of the 2- and 3-component mixture models to continuous report data. We also report the results of several simulations conducted to develop recommendations for researchers on trial numbers, set-sizes and memoranda similarity, as well as conducting parameter recovery and model recovery simulations. It is our hope that mixtur will lower the barrier of entry for utilising mixture modelling
