3D Shapes

In the past two decades, significant advances have been made to understand the psychophysical properties of visual short-term memory (VSTM). Most studies, however, make inferences based on memory for simple surface features of 2D shapes. Here, we examined the role of object complexity and dimensionality on the psychophysical properties of VSTM by comparing orientation memory for 2D lines and complex 3D objects in a delayed-response continuous report task, where memory load (Experiment 1) or axis of rotation (Experiment 2) was manipulated. In both experiments, our results demonstrate an overall cost of complexity that affected participants raw errors as well as their guess rate and response precision derived from mixture modelling. We also demonstrate that participants’ memory performance is correlated between stimulus types and that memory performance for both 2D and 3D shapes is better fit to the variable precision model of VSTM than to tested competing models. Interestingly, the ability to report complex objects is not consistent across axes of rotation. These results indicate that, despite the fact that VSTM shares similar properties for 2D and 3D shapes, VSTM is far from being a unitary process and is affected by stimulus properties such as complexity and dimensionality.

With Memory

Does the maintenance of feature bindings in visual short-term memory (VSTM) require sustained focused attention? This issue was investigated in three experiments, in which memory for single features (i.e., colors or shapes) was compared with memory for feature bindings (i.e., the link between the color and shape of an object). Attention was manipulated during the memory retention interval with a retro-cue, which allows attention to be directed and focused on a subset of memory items. The retro-cue was presented 700 ms after the offset of the memory display and 700 ms before the onset of the test display. If the maintenance of feature bindings – but not of individual features – in memory requires sustained focused attention, the retro-cue should not affect memory performance. Contrary to this prediction, we found that both memory for feature bindings and memory for individual features were equally improved by the retro-cue. Therefore, this finding does not support the view that the sustained focused attention is needed to properly maintain feature bindings in VSTM.

Short-term memory has mostly been investigated with verbal or visuospatial stimuli and less so with other categories of stimuli. Moreover, the influence of sensory modality has been explored almost solely in the verbal domain. The present study used the same experimental paradigm to investigate auditory and visual short-term memory for different types of stimuli. In each trial, participants were presented with two sequences of events, separated by a silent delay, and had to indicate whether the two sequences were identical or different. Performance in this recognition (delayed-matching-to-sample) paradigm was compared for materials that were either verbal (i.e., chained syllables without meaning) or nonverbal (i.e., not easily described by verbal labels). For the latter ones, the event sequence could either entail a contour, which is a pattern of up and down changes (based on non-pitch features), or not. All materials were implemented in both auditory and visual modalities. As previous research has reported better auditory memory (and to some extent, visual memory), and better auditory contour recognition for musicians than non-musicians, the recognition tasks were performed by a group of musicians and a group of non-musicians. Results revealed a selective advantage of musicians for the auditory no-contour stimuli and for the contour stimuli (both visual and auditory), suggesting that musical expertise is associated with specific short-term memory advantages in domains close to the trained domain, even extending cross-modally. These findings offer new insights into the role of encoding strategies and their effect on short-term memory performance across modalities.
