PSY4360.02 In-Class Activity 09/09/25
Class Activities: Research Design (Max: 10 points)
Activity 1: Design the Study Scenarios (Group Work)
Instructions: In groups, read the assigned research question and decide which design
(experimental, correlational, cross-sectional, longitudinal) best fits. Outline participants,
variables, procedures, and note strengths/limitations.
Group #: 6
Group members:
Scenarios:
1. Does caffeine improve memory performance in college students?
This experiment would go best as an experimental study. The participants would be
students who do and do not drink coffee, and the variables would be the independent
variable, which is how much coffee they drink, and the dependent variable would be the
effect on their memory. Procedures would be measuring how their memory is based on
whether they drink coffee. Limitations would be students’ honesty and whether they go
through with drinking or not drinking coffee.
2. Is time spent on social media related to anxiety levels in teenagers?
The experiment would be correlational. It’s looking at a relationship. The
participants would be teenagers who use social media and their anxiety levels. The
variables would be the independent variable, social media, and the dependent variable, the
anxiety levels. The procedure would be testing the anxiety levels of the teenagers at the end
of the given time of the study. The strengths would be being able to test a large group of
teenagers to see the cause and effects; however, the limitations would be confounding
variables like teenagers who are not assigned social media use social media.
3. How do children’s vocabulary skills develop between ages 3 and 7?
This is a longitudinal study. It’s testing the vocabulary skills over time. The
participants would be age groups of 3-7, and the variables would be the dependent variable
(the vocabulary skills) and the independent variable (age). The procedure would be testing
the children over time, and the limits could be children dropping out of the experiment.
