Exercise #1 1. Contrary to our prediction and to the findings of Struthers and Hansen (1992), we did not find cocaine-related group differences in infants’ preferences for novelty 2. a. The first hypothesis, which predicted that each of the four cognitive variables would be significantly related to adolescent worry was partially supported. b. The second hypothesis, which proposed that the four cognitive variables would contribute to the discriminant function and that the discriminant function would be effective in classifying moderate and high worriers into their respective groups, was also partially supported. c. The third hypothesis, which postulated that intolerance of uncertainty would have the strongest relationship with adolescent worry scores and would be the most important variable in discriminating between moderate and high worry groups, was supported 3. The results of this experiment contradicted our hypothesis that a belief that a vehicle crashed would increase witnesses’ perceptions of a vehicle’s speed Exercise #2 1. a. According to the analysis, the instate adjudication advantage was significantly greater on instate home grounds (15%) than on outstate home grounds (5%). That finding is consistent with previous evidence of the effect of game location on penalties. b. Nonetheless, the findings are consistent with those of previous experimental studies of in- group favoritism, insofar as the allocation of rewards promotes in-group advantage over the outgroup rather than absolute in-group gains. Exercise #3 1. a. Consequently, our study provides quantitative evidence to challenge some of the existing anecdotal evidence indicating that adoption is stigmatizing (Brodzinky, 1984; Miall, 1987).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
