The impact of perceptual fluency manipulations on processing speed and ratings of relatedness for gender role schemas using the IAT
(2016-12-15) Streich, Breeanna
The purpose of the current study was to combine research on schema violations and perceptual fluency to determine the impact of perceptual fluency manipulations on ratings of relatedness for gender role schemas through the use of an Implicit Association Test (IAT). The goal of this study was to gain a better understanding of the cognitive impact of processing manipulations. It was hypothesized that congruent blocks would have faster response times than incongruent blocks in the IAT. It was also hypothesized that perceptual fluency could be strategically manipulated to counteract the slowdown effect associated with schema-incongruent information. In addition, it was predicted that ratings of relatedness would be correlated with response times in that perceptually fluent blocks would be rated as more related than perceptually disfluent blocks. The results showed a main effect of congruency on response times and ratings of relatedness. It was found that the slowdown effect could successfully be eliminated through the use of perceptual fluency manipulations. However, perceptual fluency manipulations did not have a significant impact on ratings of relatedness. Future studies should utilize other methods to manipulate perceptual fluency, as well as investigate how changes in response times can influence different types of attribute ratings.
The impact of product health description and serving size information on consumption
(2018-08-23) Streich, Breeanna
The main goal of this study was to investigate the effects of manipulating product health descriptions and serving size information on actual calorie consumption and estimations of calorie consumption. In a 3 (no description vs. healthy description vs. unhealthy description) by 2 (normal serving size information vs. larger serving size information) factorial design, 150 females over the age of 18 years were invited to partake in a “taste test” of an oatmeal cookie product. In terms of consumption, it was found that participants who received the larger serving size information (labelled as 4 cookies/280 calories), which was double that of the normal serving size information presented on traditional packaging (labelled as 2 cookies/140 calories), consumed significantly less (M=139.92 calories, SD=98.88) than those who received the normal serving size information (M=197.98 calories, SD=145.96). Participants therefore consumed approximately 29% less when they were presented the larger serving size information compared to the normal serving size information. When looking at overall accuracy of calorie estimations or how close their estimation was to their actual consumption, it was found that those who received the larger serving size information were significantly more accurate at estimating their actual calorie consumption (M=57.42 calories, SD=73.97) than those who received the normal serving size information (M=94.70 calories, SD=109.68). Furthermore, participants presented with a healthy product description were significantly more likely to underestimate the amount of calories they consumed during the experiment (M=-52.70 calories, SD=92.25) than those who received no product description (M=-6.72 calories, SD=132.81) or an unhealthy product description (M=7.89 calories, SD=127.14). Thus, product descriptions as well as serving size information can have a significant impact on calorie consumption and an individual’s estimation of their perceived calorie intake.
