A correct-response rate of 51 percent in a two-choice picture-pointing task indicates what?

• A. A random pointing response
• B. Successful intervention
• C. Development of crucial discrimination skills
• D. Readiness to progress to a three-picture task

Answer: (A)

A correct-response rate of 51 percent in a two-choice picture-pointing task indicates a random pointing response. This rate is just slightly above the level of chance, where one would expect a correct-response rate of 50 percent if responses were purely random. In such a task, with two choices, achieving around 51 percent implies that the individual is not reliably distinguishing between the two options, as their performance is predominantly at the level of random guessing. In contrast, higher rates of success would reflect an effectiveness in answering the task. A correct-response rate closer to significantly above chance would signify intentional choice-making and the development of skills necessary to discriminate between the options. Thus, a score only slightly above chance suggests that further support or intervention may be necessary before progressing to more complex tasks.
