On what cues should social perceivers focus in order to try to detect if someone is trying to deceive others? Conversely, on what cues do social perceivers typically focus, and why are these cues less revealing?

Question

What will be an ideal response?

Answer 1

Research has shown that of the four channels of communication (i.e., words, the face,
the body, and the voice), the voice is the least controllable by the deceiver, and thus is
the most revealing cue. The voices of people who are lying, particularly when they are
highly motivated to deceive, tend to rise in pitch, and there is an increase in speech
hesitations. The next most revealing cue is the body. Fidgety movements of the hands
and feet and restless shifts in posture tend to be evident in someone who is lying.
Perceivers, however, typically focus on the less revealing cues. Perceivers tend to
focus on the words that people say, as well as on the face. This strategy is likely to fail
because people can control these channels of communication fairly well, even when
they are lying.
