STUDY 2

*Possible in class study: Show images of the two sandwiches and ask people which one they think has more calories. *

Specific hypotheses to be tested

First hypothesis: The amount of perceived amount of calories for sandwiches from a restaurant making health claims (i.e., Subway) will be lower than for sandwiches from a restaurant not making such claims.

Second hypothesis: Respondents with higher nutrition involvement will have a more accurate understanding of how many calories are in each sandwich than respondents with lower nutrition involvement, and this effect will be stronger for large sandwiches than for smaller sandwiches.

What variables are being tested? Hint: There are three IV’s and one DV.

Not to be included in slides:

IV = Sandwich Brand, Size of Sandwich, Nutrition Involvement

DV= number of perceived calories.

This study tests if your nutrition involvement will help you distinguishes the actual calorie content of the subway and MacDonald’s sandwiches. The study also tests what effect portion size has on participants calorie prediction’s. The halo effect here is that subway is perceived to be the healthier option than MacDonald’s when in fact they have the same calorie content.

Research methodology and procedures

* Participants were asked to estimate the calorie content of two different types of sandwiches and sizes respectively.

* In this case they were compared to one another

* Used a five item scale and asked respondents to answer statements such as “I pay close attention to nutrition” on a 1 = strongly disagree to 9 = strongly agree.

* This part of the study introduces the moderator “nutrition involvement”

Chart interpretation

Can anyone interpret the findings of this chart? Does anyone know what the graph would look like if high nutrition involvement did mitigate health halo effects?
