Abstract

ELLIPSES TEST - A NEW RESEARCH TOOL TO MEASURE EXTENSIVE VS INTENSIVEATTENTIONThe article presents a new computerised attention tool. Existing methods rely on assessing the effectivenessof signal detection, treating it as a result of a choice between speed and correctness (Duncan and Humphreys,1989). Their disadvantage is a lack of possibility to observe the style of working, a high level of complexity ofthe stimuli and the structure of the material, which imposes sequential method of processing. Ellipses Test isa tool which, in addition to traditional measures of effi ciency, like ommision and commision errors and speed ofwork, provides a measurement of perceptual fi eld search strategy. Two studies were carried out to evaluate itspsychometric properties. In the fi rst experiment, we manipulated intensive vs. extensive attention and compareda) the effi ciency of signal detection, b) the scanning strategy. The second experiment was conducted in a schemeof repeated measurements to test the reliability of the tool. The results indicate that the test allows to observea different method of scanning for extensive and intensive attention. The test was proven reliable and accurate.
