Laboratory Trials Research
Laboratory trials typically involve repeated presentations of stimuli (interventions or treatments) and measurements (trials). They often use equivalent materials to control the effects of memorizing. Stimuli are often presented on visual and auditory devices. They are commonly used in vision, cognitive, and human performance research. Laboratory trials also are used in materials research and testing. Examples include testing the effects of colored text and backgrounds on reading speed and comprehension and testing the effects of distractors on target detection and recognition. An industrial example might test the effects of variable temperatures on the properties of a material or product.
