Abstract

The ability to recall and manipulate information about objects and locations is known as visuospatial working memory (VSWM). One controversial idea is that the ability to form and retain visuospatial working memories is linked to our ability to make eye-movements. More specifically, locations are memorised by making a map of the eye-movements that are needed to look at those locations. This project is designed to test this idea using a new technique called eye-rotation. In this technique, participants are asked to perform memory tasks on a computer with the eye in its usual position (ie facing straight ahead) or with the head rotated by 40 degrees (so that the participant is looking at the computer out of the corner of their eye). In the rotatedcondition it is impossible for participants to plan or execute eye-movements further into the periphery. If VSWM relies on eye-movements, this manipulation (which prevents eye-movements) should lead to poorer memory performance. The project will investigate the role of the eye-movement system in three different memory processes: the formation of spatial working memories (encoding) how these memories are kept active (rehearsal) the recall of spatial information that has been stored in long-term memory (retrieval).

Data collection mode

Computer based tasks were used to measure working memory span. Experiments were run on Eprime which recorded the items presented to participants and the responses that participants made. Participants were Durham University students. There were 12 participants in Experiment 1 and 14 participants in Experiment 2, 3, & 4For each participant we collected 5 e-prime data files which recorded their memory span in different tasks (Digit Span, Corsi Blocks task, Visual Patterns Task, Size Comparison Task, Arrow Span task). The data were analysed using SPSS. Each SPSS spreadsheet contained 12 variables: Visual Frontal Nasal, Visual Frontal Temporal, Visual Abducted40 Nasal, Visual Abducted40 Temporal, Verbal Frontal Nasal, Verbal Frontal Temporal, Verbal Abducted40 Nasal, Verbal Abducted40 Temporal, Spatial Frontal Nasal, Spatial Frontal Temporal, Spatial Abducted40 Nasal, Spatial Abducted40 Temporal,Experiments 2 – 4: For each participant we collected 2 e-prime data files which recorded their memory span in different tasks (Corsi Blocks task and Visual Patterns Task). The data were analysed using SPSS. Each SPSS spreadsheet contained 12 variables:VisualFrontNasal, VisualFrontTemp, VisualAbduct40Nasal, VisualAbduct40Temp, VisualAbduct20Nasal, VisualAbduct20Temp, SpatialFrontNasal, SpatialFrontTemp, SpatialAbduct40Nasal, SpatialAbduct40Temp, SpatialAbduct20Nasal, SpatialAbduct20Temp
