Dr.Elder was interested in the way people recognize objects as members of categories.For example,what makes us recognize a dog as being a dog and not a cat? More specifically,he 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 first think about the category of "northern"? He is also curious as to whether people categorize differently if they are exposed to category members compared with generating category members.Dr.Elder 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.The results of his study are below.

-To make his study a 2×2×3 factorial design,which of the following would Dr.Elder need to do?
A)Add a second dependent variable (quality of the category attributes listed)
B)Add a new manipulated variable (time to complete the task: 5 minutes versus 10 minutes versus 15 minutes)
C)Add a new participant variable (sex: males versus females)
D)Add a new independent variable (activity condition: alone versus with a friend)

Dr. Elder can add a new manipulated variable of time to complete the task (5 minutes, 10 minutes, 15 minutes) to make it a 2x2x3 factorial design. This will allow the examination of whether more time spent on the task leads to more complex categorization. Adding a second dependent variable of quality of the category attributes listed or a participant variable of sex would not change the design to a 2x2x3 factorial design. Adding a new independent variable of activity condition (alone vs with a friend) would create a 2x2x2 factorial design, not a 2x2x3 factorial design.
