The issue of communication

Dr. MacDonald's talk is relevant to the process of interviewing/interrogating witnesses/suspects because it highlights the importance of being aware of the limitations of non-verbal cues. Interviewers should not rely solely on non-verbal cues to determine whether someone is being deceptive. They should also consider the context of the conversation and other factors that could be influencing the person's behavior.

Here are some of the key points from Dr. MacDonald's talk:

• There is no single non-verbal cue that is always associated with deception.
• Non-verbal cues can be influenced by a variety of factors, such as anxiety, trauma, and cultural norms.
• The context of the conversation is important when interpreting non-verbal cues.
• Interviewers should not rely solely on non-verbal cues to determine whether someone is being deceptive.

In this talk, Dr. Sarah MacDonald, a forensic psychologist, discusses the use of non-verbal cues to detect deception. She argues that while there are some non-verbal cues that are associated with deception, such as fidgeting and avoiding eye contact, these cues can also be caused by other factors, such as anxiety or trauma. Dr. MacDonald also discusses the importance of considering the context of the conversation when interpreting non-verbal cues.
