Question: To study the effects of primacy and recency, two groups were chosen randomly from a large sociology class. Both groups read a two-page description of a person at work, which included a paragraph telling how the person had been particularly helpful to a new employee. For half of the participants the "helping" paragraph was near the beginning (primacy), and for the other half the "helping" paragraph was near the end (recency). Afterward, each participant wrote a paragraph describing the worker's leisure activities. The dependent variable was the number of positive adjectives in the paragraph (words such as good, exciting, cheerful). Based on these data, write a conclusion about primacy and recency

Assuming that the temperature dependence of IS arises mostly because IS is proportional to n2 i , use the expression for ni in Eq. (3.2) to determine the factor by which n2 i changes as T changes from 300 K to 305 K. This will be approximately the..
