Everyday Life Activities

Working memory is a system that keeps limited information on-line for immediate access by cognitive processes. This type of active maintenance is important for everyday life activities. The present study shows that maintaining a location in spatial working memory affects the trajectories of saccadic eye movements toward visual targets, as the eyes deviate away from the remembered location. This finding provides direct evidence for a strong overlap between spatial working memory and the eye movement system. We argue that curvature is the result of the need to inhibit memory-based eye movement activity in the superior colliculus, in order to allow an accurate saccade to the visual target. Whereas previous research has shown that the eyes may deviate away from visually presented stimuli that need to be ignored, we show that the eyes also curve away from remembered stimuli.

Traumatic Memories

<p>Eye-Movement Desensitisation and Reprocessing (EMDR) is a psychotherapy that incorporates the use of saccadic Eye-Movements (EM) to alleviate distress caused by traumatic memories. Although EMDR is recognised as a front-line treatment for individuals suffering from Posttraumatic Stress Disorder (PTSD), the mechanisms underlying the efficacy of the EM component remain a point of contention. The aim of the current research was to investigate first, whether EM reduced ratings of memory vividness and emotionality by taxing Working Memory (WM) capacity, and second, to examine whether EM lowered the number of intrusive thoughts under two opposing suppression conditions. In two experiments, 244 non-clinical participants were asked to recall an unpleasant memory while simultaneously engaging in fast-EM, slow-EM or a no-EM control. Participants then received an instruction to intentionally avoid thinking about the memory, or to think about whatever came to mind. Relative to no-EM, fast-EM and slow-EM had no significant effect on vividness and emotionality ratings, nor did they influence the number of intrusive thoughts. In addition, the level of suppression intent had no impact on memory outcomes. Overall, the results from these two experiments oppose earlier findings in support of WM theory, and a significant body of research that has demonstrated the efficacy of the EM component. Implications for the EM component in EMDR are discussed, and an alternative explanation for EM is offered.</p>

Attention Shifts

We have previously argued that rehearsal in spatial working memory is interfered with by spatial attention shifts rather than simply by movements to locations in space (Smyth & Scholey, 1994). It is possible, however, that the stimuli intended to induce attention shifts in our experiments also induced eye movements and interfered either with an overt eye movement rehearsal strategy or with a covert one. In the first experiment reported here, subjects fixated while they maintained a sequence of spatial items in memory before recalling them in order. Fixation did not affect recall, but auditory spatial stimuli presented during the interval did decrease performance, and it was further decreased if the stimuli were categorized as coming from the right or the left. A second experiment investigated the effects of auditory spatial stimuli to which no response was ever required and found that these did not interfere with performance, indicating that it is the spatial salience of targets that leads to interference. This interference from spatial input in the absence of any overt movement of the eyes or limbs is interpreted in terms of shifts of spatial attention or spatial monitoring, which Morris (1989) has suggested affects spatial encoding and which our findings suggest also affects reactivation in rehearsal.
