Summary
Exposure to diverse stimuli of a person, like various facial expressions, enhances likability more than repeated exposure to a single stimulus. This finding extends the mere exposure effect by highlighting the impact of stimulus variability.
Area of Science:
- Social Psychology
- Cognitive Psychology
- Human Perception
Context:
- The mere exposure effect suggests repeated stimulus exposure increases liking.
- Previous research focused on frequency of exposure to identical stimuli.
- This study explores if stimulus variability impacts likability more than repetition.
Purpose:
- To investigate if multiple subliminal exposures to varied stimuli of the same person enhance likability.
- To compare the effect of multi-angle and multi-expression exposures against single-stimulus repetition.
Summary:
- Participants underwent subliminal exposure to a person's face from multiple angles or with various expressions.
- Likability was measured using the Go/No-go Association Task.
- Multi-angle exposure effects were similar to 21 repetitions of a single image; multi-expression exposure significantly increased likability compared to single expressions.
Impact:
- Findings suggest stimulus variability, particularly diverse facial expressions, is more effective for increasing likability than simple repetition.
- This research offers insights into optimizing social perception and interpersonal attraction through varied stimuli.
- Results contribute to understanding the nuances of the mere exposure effect in social cognition.

01:23McNemar's Test
McNemar's Test is a nonparametric statistical test used to determine if there is a significant difference in proportions between two related groups when the outcome is binary (e.g., yes/no, success/failure). It is beneficial when we have paired data, such as pre-test/post-test designs, where the same subjects are measured under two different conditions. The test is named after the statistician Quinn McNemar, who introduced it in 1947. It is commonly used in situations where subjects are...
01:13Multiple Comparison Tests
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
