analysis of a psychology research paper.

Need help with analysis of a psychology research paper. Answer Questions 1-6: Name the independent and dependent variables used in the first experiment; include all the levels of each variable. (maximum 2 sentences, 1 point) Are there any methodological flaws or limitations in the experimental design? Explain. (Note that small sample size and lack of diversity of the subjects are not sufficient limitations for this question, as how visual perception works is not expected to vary significantly between individuals, and sample sizes of 3+ subjects are common in psychophysical experiments). (maximum 3 sentences; 2 points) How did the experimenters control for possible confounding variables? Explain. (maximum 3 sentences, 2 points) Explain the preconstancy and postconstancy views of perceptual grouping. How are these two views related to whether perceptual grouping operates early or late in visual processing? (maximum 5 sentences, 4 points) What did the authors find, and what are the implications of those findings? Relate your answer to a sensation or perception topic that you have learned about in this class. (maximum 5 sentences, 3 points) Design an experiment that will look at perceptual grouping using another Gestalt principle of grouping (e.g., proximity) or another type of constancy (e.g., size, shape) (maximum 1 page, 7 points as detailed below) 1) What methods would you use? (e.g., describe your stimuli, your task, etc.) Be clear and detailed in your description. (3 points) 2) What do you expect to find? (2 points) 3) What would be the implications of your findings? (try to talk about this with regard to the article and sensation/perception in general) (2 points)
