“…Second, serial recall of imitation components was assessed by means of free imitation of the stimulus model, as opposed to the constrained, discrete measures used in most other studies. Finally, error is regarded as a continuous variable, rather than a binary one, such as correct or incorrect (see Farrand et al 2001;Rhodes et al 2004). This is arguably more applicable to real-life tasks, which often involve dynamic objects, and are repeated by an observer whose goal is a reproduction that is roughly isomorphic with the model, but not necessarily identical to it (Schaal et al 2003).…”

A fundamental challenge in neuroscience is to understand the mechanisms by which multicomponent actions are represented and sequenced for production. We addressed this challenge with a movement-imitation task in which subjects viewed the quasi-random, two-dimensional movements of a disc and then used a stylus to reproduce the remembered trajectory. The stimulus disc moved along straight segments, which differed sufficiently from one another that it was possible to trace individual segments' fate in the resulting movement imitation. A biologically based segmentation algorithm decomposed each imitation into segments whose directions could be compared with those of homologous segments in the model. As the number of linked segments in a stimulus model grew from three to seven, imitation became less accurate, with segments more likely to be deleted, particularly from a model's final stages. When fidelity of imitation was assessed segment by segment, the resulting serial position curves showed a strong primacy effect and a moderate recency effect. Analysis of pairwise transposition errors revealed a striking preponderance of exchanges between adjacent segments that, along with the serial position effects, supports a competitive queuing model of sequencing. In analogy to results with verbal serial recall, repetition of one directed segment in the model reduced imitation quality. Results with longer stimulus models suggest that the segment-by-segment imitation generator may be supplemented in the final stages of imitation by an error-signal driven overlay that produces a late-course, real-time correction. Results are related to neural mechanisms that are known to support sequential motor behavior and working memory.

“…Retention is tested immediately after presentation, when all dots are re-presented simultaneously in their original locations and the participants are required to mark them, using a mouse-driven pointer, in their order of presentation. Primacy and recency effects are found in such a task, but more noteworthy is that recency is of a magnitude approaching that found typically in auditory verbal serial recall tasks (Farrand & Jones, 1996;Farrand, Parmentier, & Jones, 2001;Jones et al, 1995). This suggests that marked recency is not a defining characteristic of auditory serial recall; a visuospatial task that requires serial recall may exhibit it also.…”

The suffix effect-the loss of recency induced by a redundant end-of-list item-was studied in a visuospatial serial recall task involving the memory for the position of dots on a screen. A visuospatial suffix markedly impaired recall of the last to-be-remembered dot. The impact on recall was roughly of equal magnitude whether the suffix shared attributes with the to-be-remembered dots (Experiment 1) or was visually distinct (Experiments 2 and 3). Although the presence of a tone suffix also impaired serial memory for the last items in the sequence, the impact of a visuospatial suffix was more marked, implying a specific as well as a possible general effect of suffix in the visuospatial domain (Experiment 4). The suffix effect seems not to be a phenomenon confined to verbal material but rather a universal phenomenon possibly related to grouping.

“…In Experiment 1, we sought to test De Lillo's (2004) suggestion of a hierarchical organization based on spatial proximity while avoiding the limitations pointed out above by using the dots task (Farrand & Jones, 1996;Farrand, Parmentier, & Jones, 2001;Jones et al, 1995;Tremblay et al, 2001) rather than the Corsi task, and by including a control condition in which locations did not form spatial groups. We predicted that performance should be best when locations were temporally and spatially proximate, intermediate in the absence of spatial groups, and weakest when temporal and spatial proximity clashed.…”

Organization of visuo-spatial serial memory: interaction of temporal order with spatial and temporal grouping

This study investigates whether memory for sequences of spatial locations can be represented hierarchically, that is, as successive groups containing the order of constituent locations. Two grouping manipulations are used: Temporal grouping, based on the verbal serial memory literature, and spatial grouping, based on recent empirical work on visuo-spatial serial memory. In Experiment 1, we examine the relationship between spatial grouping and temporal order and showed that recall performance increases when both temporal and spatial organization correlate, but decreases when they clash. Experiments 2 and 3 show that the latter result is confounded by differences in path length (length of spatial path defined by the locations) between conditions, and that no effect of the spatial organization is observed when path length is controlled for. In Experiment 4, an alternative method to spatial grouping, temporal grouping, is used to induce hierarchical organization. A recall advantage is found in the temporal grouping condition. The results suggest that hierarchical representations can be imposed on order information for visuo-spatial sequences, either when participants have pre-existing knowledge about the form of the path formed by the sequence or when temporal boundaries delimit chunks; that increased path length is the cause of the performance decrement observed when dots from separate spatial groups are presented successively; and that path length and more generally sequence characteristics should be taken into account in designing future research on visuo-spatial serial memory.
