errors in time, color (color recall procedure), temperature and accuracy
perception (measured-estimated difference).
Secondary outcome
Medication use, mood severity, demographic characteristics.
Background summary
Earlier studies have shown that mood has an influence on time estimation and
color perception. We want to investigate these and other forms of perception
are influenced by depressed or hypomanic mood in a bipolar population.
Study objective
We want to identify perception biases in bipolar patients with both depressive
and hypomanic mood symptoms.
Study design
Between-subjects design with two clinical groups.
Study burden and risks
Participants will perform a 30 to 45-minute assessment, including a computer
task and the assessment of several questionnaires. The burden and risks are
minimal. These particular groups were chosen because earlier research has shown
an effect of mood on several recall tasks; we will try to replicate this
finding with a bipolar sample. No invasive or other medical procedures will be
performed.
