The effects of grouping and cueing in the performance of location tasks
Interior Design and Furnishings
In location tasks such as assembly of a control panel, operators respond to stimulus information by locating a given target in an extensive set of response alternatives. Arrangement of the response alternatives and the method of presenting the location information (cueing), as well as the interaction between these factors, were hypothesised to influence performance in this type of task. To test these hypotheses, a factorial experiment involving 60 subjects was performed in which five levels of grouping and four levels of cueing were investigated. Grouping appeared to affect location accuracy more than location time, whereas the effects of cueing were found to be significant for both location accuracy and time. The absence of an interaction effect between grouping and cueing suggested that the effects of these factors on performance were independent.
