Create a two-part paper using your notes from the preparatory steps. In the first part, describe a battery of six to seven tests to understand Kayla's disorder. For each test, identify the cue that's used to infer depth and design a behavioural test to assess whether Kayla uses that cue. Consider how an experiment can be designed to test this cue, including the stimuli you can present and Kayla's expected response if she infers depth incorrectly. Also, discuss the possibility of deficits that damage multiple depth cues simultaneously.
Now, let's say Kayla struggles with one or two of the tests but aces the others. (You decide which ones she struggles with!) Your task is to explain how you'd use these results to form a hypothesis about the neurological source of Kayla's difficulties. For instance, if she fails the size constancy test, what brain processes could be the culprit? Maybe you could look for studies online that explore how our visual cortex enables us to perceive size constancy. Ultimately, you need to detail a set of tests and what you can infer from their outcomes. This is where you can really show off what you know. Don't just list the different depth perception cues. Instead, you need to connect these cues to the psychological processes that could explain her observed behaviour.
In the second section, detail a rehabilitation program tailored for Kayla. What specific strategies can address her depth-perception disorder? Consider the techniques Sue Barry employed to correct her binocular vision, but avoid simply replicating them, as they might not be suitable for Kayla. Instead, be creative. Consider the psychological processes involved in the flow of visual information, from the retina through the visual cortex. Identify which processes are impaired in Kayla. Can physical therapy help? If there's neurological damage, full recovery might be impossible, but she could still learn compensatory strategies. Perhaps, similar to Sue, Kayla developed a counterproductive coping mechanism as a child that can be unlearned. When outlining this rehabilitation program, provide specific details. Avoid vague suggestions; instead, create a schedule for Kayla, including milestones to track her progress.
