“…It has been shown that Corsi sequences are processed configurationally by encoding the location of each item in the sequence in relation to the other icons in the display rather than on the basis of egocentric coordinates centred on the body of the participant (Avons, 2007;Avons & Trew, 2006). Some facilitating effects for clustered sequences could stem from the particular visual shapes obtained by mentally drawing the connections between items in clustered sequences and using visual memory to help guiding their recall.…”

“…It has been shown that intrinsic spatial coordinates are used for coding the position of each item in a Corsi display (Avons, 2007;Avons & Trew, 2006) and that the display is processed configurationally (Boduroglu & Shah, 2006). Nevertheless, the display of items in the Corsi test is typically irregular (see Berch, Krikorian, & Huba, 1998 for a review) and, with some notable exceptions discussed later, systematic assessments of how spatial structure affects recall are rare.…”

“…Performance was impaired when the template was moved between the display of each location during presentation, but not when the same translation movements occurred during the recall phase (Avons, 2007, Experiments 1 and 2). Avons and Trew (2006) also found that performance was disrupted when template movements occurred in the retention interval. One account proposes that interference arises from the conflicting demands posed by encoding (or rehearsing) the sequence while monitoring the moving template.…”

1068This article will describe a new method for identifying the spatial reference frame used to encode a sequence of spatial locations. The method is quite general and can be applied in any situation in which two reference frames can be moved in relation to each other in a controlled manner. Here, the method will be used to address concerns about the nature of the reference frame and the involvement of movement interference in spatial span, a task commonly used to estimate spatial short-term memory (STM). Spatial span provides an ideal vehicle for illustrating the method, so we shall first review recent findings and issues concerning spatial span and then proceed to describe the method. Spatial SpanIn spatial span, a sequence of discrete spatial locations is presented at a fixed rate in full view of an observer. The observer's task is to remember the sequence and reproduce it by pointing to the locations of the sequence in the correct order. The task was initially devised by Corsi (1972) as an analogue of digit span and was presented as an array of nine wooden blocks fixed to a rectangular board. The experimenter indicated a spatial sequence by tapping each block in succession. The Corsi task can readily be adapted to computerized presentation, in a format in which the board is shown in plan view as a rectangular frame enclosing a number of squares and the sequence is indicated by highlighting each square in turn. With computer presentation, the configuration is more flexible; for example, the positions of the squares can be varied across trials, rather than fixed, and the number of squares can vary. In addition, computer presentation allows the visibility of the tokens during presentation to be controlled. In the original Corsi task, all the possible locations, which were fixed objects, were visible throughout presentation and recall. In the form of the task used here, only one spatial token is displayed at a time during presentation, derived from the dots task developed by Jones and his colleagues (Jones, Farrand, Stuart, & Morris, 1995). In all cases, all the potential spatial locations are visible during recall, when the observer reconstructs the sequence. For a review of spatial span and its clinical applications, see Berch, Krikorian, and Huha (1998).A number of dual-task studies have explored the effect of various kinds of interference presented concurrently with the spatial sequence or during the retention interval. These studies have consistently shown impairment caused by spatial tapping, by spatial attention shifts, and by directing eye movements to irrelevant targets (e. (Smyth, Pearson, & Pendleton, 1988). One interpretation is that the sequence of locations is remembered in the form of a motor plan, so that any task that engages movement control processes will produce interference. A similar account has been proposed to explain interference with visual imagery tasks (e.g., Baddeley, 1986;Logie, 1995;Postle, Idzikowski, Della Sala, Logie, & Baddeley, 2006). Others have argued that movement and ocul...
