RESEARCH STUDY: Dr. Singh wаs interested in the wаy peоple recоgnize оbjects аs members of categories. For example, what makes us recognize a dog as being a dog and not a cat? More specifically, she was curious as to whether people think about categories in a more complex way if they contemplate an “opposite” category first. For example, does a person think differently about the category of “southern” if they are also thinking about the category of “northern”? She was also curious as to whether people categorize differently if they are shown examples of those categories (e.g., looking at pictures of different animals) compared with generating those examples themselves (e.g., drawing pictures of different animals). Dr. Singh has four groups of participants (with 30 people in each group). In Group A, participants were told to cut out pictures of dogs and cats from magazines. In Group B, participants were told to cut out pictures of just dogs from magazines. In Group C, participants were told to draw pictures of cats and dogs. In Group D, participants were told to draw pictures of just dogs. After doing this for 30 minutes, participants in all groups were asked to list the attributes that define the “dog” category. Having a higher number of attributes listed was considered to be an indication of thinking about the category in a more complex way. Dr. Singh also was curious as to whether categorization happens similarly for children as it does for adults. As such, she recruits a group of 10-year-olds and a group of 20-year-olds to participate in the study. The results are below. Based on the graphs above, Dr. Singh should conclude which of the following?
