The participants' improved performance over time suggests a practice effect, which occurs when repeated exposure to a task leads to improved performance as individuals become more familiar with the task and develop more efficient strategies. Contrarily, a fatigue effect would imply worsening performance over time, a boredom effect would imply disengagement or lack of motivation, and a contrast effect would involve performance being influenced by previous experiences or stimuli.
