December 5, 2007

The 11th annual Dordt College Psychology Student Research Conference will be held Wednesday, Dec. 12, 3:30-5:00 p.m., at the Campus Center’s Eckhardt Lounge. The public is invited to attend.



Presenters are 10 students in an experimental psychology course taught by Dr. Sherri Lantinga. Participants designed original experiments, collected and analyzed data, and compiled their findings. Their PowerPoint presentations are as follow:

Samuel Zylstra (Munster, IN) and Jeremiah Kats (Boise, ID) studied the effect of caffeine on working memory capacity in regular and irregular caffeine consumers. Their study evaluated 51 undergraduate students who either did or did not consume caffeine before doing a computerized working memory task.

Jaime Altena (Sioux Center) and Kayla Dykstra (Hudsonville, MI) studied the effect of male presence on food consumption in college females. They examined the food consumption of 47 female participants with and without males present.

Stephanie Van Voorst (Sioux Center) and Georgina Aquino (Curenavaca, Mexico) studied the effect of color on test performance, focusing on the relationship between emotional response to color and its effect on test performance.

Jeanetta Groenedyk (Downs, KS) and Karyn Zuidhof (Lacombe, Canada) examined the effects of clothing on children’s perceptions of likability. They gathered the responses of 89 children to a booklet with questions about pictures of men in either casual or formal attire.

Paulina Aquino (Curenavaca, Mexico) and Beverly Leusink (Abbotsford, Canada) assembled a poster presentation on the effects of college experience on reading rate and comprehension. They will be available for questions from 4:30-5:00 p.m. Aquino and Leusink asked 66 undergraduates to participate in a reading comprehension test after reading either a long or a short essay. Their comprehension test scores were compiled according to class standing and essay length.
