KIN 315 Motor Learning Fall 2009 Name Lab 6 Working Memory: Remembering Limb Movements Introduction Purpose: To demonstrate the characteristics of working memory for remembering limb movements. Different retention interval conditions are compared to determine how each condition influences retention test performance. Forgetting is inferred from the amount of error occurring during the retention test, which means that a higher amount of error indicates that more has been forgotten. Task and Equipment Needed The task is a line-drawing task. The blindfolded participant draws a line of a self-selected length along a ruler or straight-edge. This drawing activity is followed by a retention interval of a specified length which may or may not include an activity. After the retention interval the blindfolded participant attempts to draw a line that is the same length as the previously drawn line. Equipment • Pencil • Blindfold • Blank paper (3 sheets) • Ruler or straight-edge Procedures Organize the students in pairs. One should be designated the participant and one the experimenter. They should be seated so that they face each other. The participant experiences three trials in each of three different retention interval conditions (nine total trials): (1) Immediate recall; (2) 20-sec. unfilled retention interval; and (3) 20-sec. filled retention interval. Each trial involves the following protocol: (1) Goal movement - The participant draws a line of a desired length along the ruler or straight-edge. (2) Retention interval - The participant engages in the requirements of the retention interval. (3)
