This study examined the effects of context on emotional ratings using standardized ratings to form 3 levels of images. Participants, shown only 1 level of context, rated each image using a Likert Scale. We proposed that if context effects infl uence emotional ratings, then ratings would differ by weighted stimulus contexts. Results indicated that context effects altered how participants rated images. However, when participants were informed to be aware of context effects, ratings were closer to standardized ratings. These results show that emotional responses are infl uenced by context and further, that awareness of context can overcome this infl uence.
APPENDIX Task RulesRule 1. Participants had to correctly identify whether units were to be placed on a truck, or sent to the pick-up order window based on the label associated with the unit.Rule 2. Participants were required to ship units labeled as "regular" within two task-days (4 min in real time), and units labeled as "rush order" within one task-day (2 min in real time).Rule 3. Participants were required to dispatch trucks to no more than three out of fi ve available shipment zones.Rule 4. Each of the units displayed were labeled with a particular business name. Units with the same business names were to be shipped together on one truck rather than dispersed between several trucks.Rule 5. Each truck had a limited capacity, and participants were required to limit loads on each truck to that capacity. Rule 6. Trucks exceeding their capacity by more than 20% were not dispatched.
Rule 7.Orders fi rst appeared in the "queue, " which was a waiting list of orders not yet accepted. Participants were required to accept orders from the queue within one task day (2 min in real time).PSI CHI JOURNAL OF UNDERGRADUATE RESEARCH | SUMMER 2010
