Define what a practice effect is in the context of psychological research and identify the specific type of experimental design in which it occurs.
Question: Define what a practice effect is in the context of psychological research and identify the specific type of experimental design in which it occurs.
Sample answer: A practice effect is a specific type of carryover effect that occurs in within-subjects experiments. It happens when participants perform better on a task in later experimental conditions not because of the actual experimental manipulation, but because they have gained experience and had the opportunity to practice the task during earlier conditions.
Key points:
- Identifies the practice effect as a type of carryover effect.
- Specifies that it occurs in within-subjects experiments.
- Explains that performance improves in later conditions due to gained experience.
- Clarifies that the improvement is not caused by the experimental manipulation.
Rubric: Full credit requires stating that it is a carryover effect, identifying that it happens in within-subjects experiments, and explaining that performance improves due to prior experience or practice rather than the experimental manipulation.

In a within-subjects experiment, which of the following accurately describes a practice effect?
Arrange the following steps in the correct chronological order to illustrate how a practice effect typically develops within a within-subjects research design.
A researcher is testing whether a specific type of background music improves productivity on a repetitive data-entry task using a within-subjects design. Participants work in silence for 30 minutes, followed by 30 minutes of working with the music. If the participants' speed increases during the music condition primarily because they became more efficient at navigating the data-entry software during the initial silence condition, this improvement is an example of a practice effect.
A researcher is analyzing the results of a within-subjects study on puzzle-solving speed. Match each specific observation with the explanation that best identifies the cause of the participant's performance change.
In a within-subjects experiment, a practice effect occurs when participants perform a task better in later conditions simply because they gained experience with the task in earlier conditions, rather than because of the experimental manipulation.
Why does a practice effect present a challenge when interpreting the results of a within-subjects experiment?
A researcher interprets an improvement in puzzle-solving speed between two trials as evidence that a new 'nootropic' coffee is effective. To evaluate the internal validity of this interpretation, a peer reviewer would argue that the study is confounded by the _____ effect, as participants likely became more efficient at the task through experience.
Match each hypothetical research scenario to the experimental design concept it best exemplifies.
A researcher conducts a within-subjects study where participants solve math puzzles under two lighting conditions. If participants perform faster in the second condition purely because they became familiar with the puzzle format during the first trial, this threat to internal validity is called a _____ effect.
Arrange the steps a researcher would take to design and evaluate a within-subjects study to determine whether a practice effect is confounding the results.
Define what a practice effect is in the context of psychological research and identify the specific type of experimental design in which it occurs.
Based on the concept of practice effects, explain why Dr. Smith's conclusion might be flawed and describe the alternative reason that could explain the participants' faster performance on the second puzzle.
A researcher conducts a within-subjects study requiring participants to shoot free throws with two different types of basketballs. If participants score more points with the second basketball solely because they warmed up and got used to the shooting motion while using the first one, what specific phenomenon is affecting the results?
