Verified step by step guidance

1. Understand the concept of 'first impression' in psychology, which refers to the initial perception or judgment we form about another person upon meeting them.
2. Recognize that research in emotional processing and social cognition has investigated the speed at which these impressions are formed.
3. Recall that studies using methods like rapid exposure to faces and measuring brain responses have shown that first impressions can be formed extremely quickly.
4. Note that the key finding is that a first impression can be formed in as little as one-tenth of a second, highlighting the brain's rapid processing capabilities.
5. Therefore, the correct answer is that first impressions can be formed in as little as 0.1 seconds, rather than requiring minutes or hours of interaction.
