Based on the concept of carryover effects, explain why the ratings for the average-looking individual were skewed in this experiment. In your response, identify the specific carryover effect occurring and explain how the sequence of exposure led to this outcome.
Case context: A researcher is conducting a study on social judgment. Participants in the experiment are first asked to evaluate a highly attractive individual. Immediately afterward, the same participants are asked to evaluate an average-looking individual. The researcher notices that the participants judge the average-looking individual much more harshly than participants who rate the average-looking individual without first seeing the highly attractive individual.
Question: Based on the concept of carryover effects, explain why the ratings for the average-looking individual were skewed in this experiment. In your response, identify the specific carryover effect occurring and explain how the sequence of exposure led to this outcome.
Sample answer: The ratings were skewed due to a context effect (or contrast effect), which is a specific carryover effect. Because participants were tested in the highly attractive condition first, this initial condition altered how they perceived the stimulus in the subsequent condition. The sequence of exposure skewed their judgment of the average-looking individual, causing them to rate that individual more harshly.
Key points:
- Identifies the phenomenon as a context effect or contrast effect
- Explains how the sequence of exposure (the order of conditions) skews judgment
- Explains that testing in the first condition alters the participant's perception of stimuli in the subsequent condition
Rubric: Grading Rubric: - 2 points: Identifies the phenomenon as a context effect (or contrast effect). - 2 points: Explains that it is a carryover effect arising from the sequence of testing conditions. - 2 points: Demonstrates comprehension of the mechanism: exposure to the first condition alters the perception of the stimuli or task interpretation in the later condition.

Which of the following best defines a context effect in psychological research?
Arrange the steps that describe how a context effect influences a participant's judgment during a psychological research study.
In a research study where participants complete multiple tasks in a specific sequence, the initial condition (the context) can influence how they perceive subsequent stimuli. Match each experimental 'context' with the most likely 'contrast effect' on the participant's perception of the stimulus in the next condition.
In a psychological study on social judgment, a researcher finds that participants rate an average-looking individual as 'unattractive' only when they have just finished evaluating a highly attractive person. This shift in judgment represents a context effect because the initial exposure to the attractive person established a subjective frame of reference that skewed the perception of the subsequent individual.
In within-subjects research designs, which of the following statements best explains how a context effect (or contrast effect) skews a participant's responses?
In a within-subjects experiment, participants who first evaluated a highly attractive defendant subsequently rated an average-looking defendant more harshly than if they had not seen the attractive defendant first. This shift in judgment caused by the sequence of conditions is called a(n) _____.
To evaluate the validity of a researcher's claim that a stimulus is 'objectively' weak, a reviewer must determine if the sequence of testing has created a _____ effect, which would mean the participant's judgment was skewed by a relative comparison to a preceding high-intensity condition rather than being an absolute measurement.
A researcher uses a within-subjects design in which participants first rate the performance of an exceptionally skilled musician and then rate the performance of a moderately skilled musician. Participants give the second musician lower scores than a separate group of participants who rated only the moderately skilled musician. Labeling this rating difference a context effect is the correct interpretation of the pattern.
A researcher suspects that sequential testing has distorted participant responses in a within-subjects experiment. Match each concept with the specific role it plays in producing or explaining a context effect.
A peer reviewer is critically evaluating a within-subjects experiment to judge whether a context effect undermines the validity of the study's conclusions. Order the steps of this evaluation from first to last.
Define a context effect (or contrast effect) in the context of psychological research, and recall how it operates as a specific type of carryover effect.
Based on the concept of carryover effects, explain why the ratings for the average-looking individual were skewed in this experiment. In your response, identify the specific carryover effect occurring and explain how the sequence of exposure led to this outcome.
If a within-subjects design requires participants to evaluate a highly attractive person followed by an average-looking person, apply the concept of a context effect to predict how this sequence will affect the ratings of the average-looking person and briefly explain the underlying mechanism.
