- Abstract
The Assessment of Basic Learning Abilities (ABLA) assesses the ease or difficulty with which individuals with intellectual disabilities are able to learn a simple imitation and five two-choice discriminations, referred to as levels. During ABLA Level 2, referred to as a position discrimination (Kerr, Meyerson, & Flora, 1977), the client is presented with a yellow can always on the left and a smaller red box always on the right, and the correct response is to place an irregularly shaped piece of foam into the container on the left (the yellow can). With this task a client can learn to make a correct response based on position, colour, shape, or size cues, or some combination of these. The current study evaluated the relative difficulty of ABLA Level 2 and two additional types of position discriminations. The second type of task was similar to ABLA Level 2, except that it used identical containers, and thus contained both relative and absolute position cues, but not shape, colour, or size cues. The third type of task was similar to ABLA Level 2; however, it incorporated identical containers that varied in their absolute positions, which required a relative position discrimination to arrive at the correct response. In two experiments that each used a single-subject design with replication across three participants who passed ABLA Level 2 but failed all higher levels, the results demonstrated that there was no consistent difference in difficulty between the three types of tasks.
