What scale did participants use to measure guilt or innocence after the transcript?

1. A 5-point scale

2. A 10-point scale

3. A 7-point scale

4. A verbal response scale

The correct answer is: A 7-point scale

The correct answer is the use of a 7-point scale for participants to measure guilt or innocence after analyzing the transcript. A 7-point scale provides a moderate number of response options, which allows participants to express varying degrees of certainty or ambivalence regarding guilt or innocence. This is particularly useful in psychological research, as it captures a range of opinions and feelings that might be more nuanced than a simple binary choice (guilty or not guilty). Using a scale with more points than a simple thumbs up or thumbs down can lead to more detailed data, which is essential in understanding the complexity of judgments like guilt. A 7-point scale strikes a balance, giving enough granularity without overwhelming the participants with too many options, which could lead to confusion or inconsistency in their responses. This method is often preferred in psychological assessments and studies because it facilitates a more in-depth understanding of participants' perceptions, attitudes, or beliefs. Consequently, the choice of a 7-point scale is especially relevant in scenarios where emotional and cognitive evaluations are being measured, such as in judgments of guilt or innocence.
