“…Our findings indicate that symmetry facilitates the tactile processing of stimuli, even when it is an incidental encoding property and participants' attention is not focused on this property, because participants were not informed that some configurations would be symmetric. This finding is consistent with other studies showing that symmetry enhances visual memory in an automatic fashion [51,52]. However, a critical difference emerged in the performance of sighted and blind participants related to the orientation of the symmetry axis.…”

“…Using a similar task in the visual modality, Rossi-Arnaud and colleagues [51,52] found that the presence of symmetry (although irrelevant for the purpose of their task), facilitated the memory retrieval of target patterns. Our aim was to determine whether this was also the case in blind individuals when perceiving similar configurations in the haptic domain.…”

Symmetry Detection in Visual Impairment: Behavioral Evidence and Neural Correlates

Bilateral symmetry is an extremely salient feature for the human visual system. An interesting issue is whether the perceptual salience of symmetry is rooted in normal visual development. In this review, we discuss empirical work on visual and tactile symmetry detection in normally sighted and visually impaired individuals. On the one hand, available evidence suggests that efficient visual symmetry detection may need normal binocular vision development. On the other hand, converging evidence suggests that symmetry can develop as a principle of haptic perceptual organization in individuals lacking visual experience. Certain features of visual symmetry detection, however, such as the higher salience of the patterns containing a vertical axis of symmetry, do not systematically apply to the haptic modality. The neural correlates (revealed with OPEN ACCESS Symmetry 2014, 6 428 neuroimaging) associated with visual and haptic symmetry detection are also discussed.

“…Thus, we can argue that features within the separated conditions were bound together in some form during encoding and maintenance. Although the data do not allow a specification of the precise nature of this binding and the underlying representations, it is emerging that the creation of bindings is relatively cost free in terms of attention even when factors such as continuation and symmetry also appears to be relatively cost free in terms of attentional resources, with demanding concurrent activity again failing to cause differential disruption (Rossi-Arnaud et al, 2006;Woodman et al, 2003). It seems plausible to assume that these binding processes operate at a relatively peripheral perceptual level, before the resultant binding is registered in working memory.…”

Binding across space and time in visual working memory

292Perceiving the world involves simultaneously processing across a range of channels of separable features, such as shape, color, and location, followed by a process in which they are bound together into objects, scenes, and episodes. The subsequent binding processes and the temporary storage involved have formed a major focus for recent work in the area of visual short-term and working memory (e.g.,

“…An important factor in remembering such an array is that of symmetry, with patterns having vertical symmetry being more memorable. This effect was studied by Rossi-Arnaud, Pieroni and Baddeley (2006) using a sequential method of presentation such that the participants were required to observe and then reproduce a pattern of stimuli, each comprising a sequence of locations on a 5 by 5 matrix, after which the participant had to recall the array. Patterns could be symmetrical along a vertical, horizontal or diagonal axis, or could be asymmetric.…”

Investigating the episodic buffer

A brief account is presented of the three-component working memory model proposed by Baddeley and Hitch. This is followed by an account of some of the problems it encountered in explaining how information from different subsystems with different codes could be combined, and how it was capable of communicating with long-term memory. In order to account for these, a fourth component was proposed, the episodic buffer. This was assumed to be a multidimensional store of limited capacity that can be accessed through conscious awareness. In an attempt to test and develop the concept, a series of experiments have explored the role of working memory in the binding of visual features into objects and verbal sequences into remembered sentences. The experiments use a dual task paradigm to investigate the role of the various subcomponents of working memory in binding. In contrast to our initial assumption, the episodic buffer appears to be a passive store, capable of storing bound features and making them available to conscious awareness, but not itself responsible for the process of binding.like André, I regard executive control as being at the heart of working memory (Vandierendonck, De Vooght & Van der Goten, 1998). I have however, always regarded analysing it as presenting a very tough problem. For many years I attempted to tackle the problem, by postulating a central executive that was capable of performing all of the many functions required by our multicomponent model, apart from those that could be assigned to the phonological loop or the visuo-spatial sketchpad. In short, the central executive was an allpowerful homunculus, a little man who ran the whole working memory show.This served the function of allowing us to concentrate on the more tractable questions of understanding the visuo-spatial and phonological subsystems, but was clearly not satisfactory. This became abundantly clear when, in writing my 1986 monograph, I reached the end of the first draft and realised that I had completely left out the central executive. Rather than starting again from scratch, I decided to borrow an attentional control model from elsewhere. But which model? This turned out not to be a problem since, although there were a number of models concerned with the attentional control of perception, we needed an action control mechanism. choosing a suitable model proved easy, as there only appeared to be one, that proposed by norman and Shallice (1986).
