CMN 122 Final Exam Study Guide
1. Which communication channel is it easier/harder to detect when someone is being deceptive. Which
channel is it easier/harder to successfully tell a lie? - Answer -Clues to Lying:
-voice pitch is a more dependable indicator than facial expression
-ears are better than eyes at distinguishing truth from falsehood
-tone in which words are spoken=very valuable indicator as to whether someone is lying (434)
-face=least leaky channel, best liar
-person's ability to deceive varies with the sending capacity of the channel that is ued
-the greater that channel's sending capacity (the more messages it can send, the more quickly it can
send them, the more visible they are) then the more deceptive that channel can be
-face has maximal sending capacity, esp well equipped to tell lies
-the body is less controllable, slower, less obvious; reduced sending; reduced sending capacity makes
lying with the body difficult, but it also makes the body a leaky channel: Gestures and other body
movements (fidgeting, signs of nervousness) often betray deceit (436)
-hierarchy of "leaky channels"; Rosenthal put discrepancies between two channels of cmn (smiling face
w/ angry voice) at top of list as leakiest
-next came fleeting body movements or facial expressions, tone of voice, body in general, lastly the face
, -discrepancy=leakiest of channels; involves two modes of cmn that are hard to control simultaneously
(435)
6. What are the olfactory communication myths for humans? - Answer -1.Humans have smaller "smell
brains" than the rest of the animal kingdom
--olf bulb has been there all along, just harder to find
2.We're above scent-driven socialization
--body scents important in mate attraction, aromatic by products of the immune system
3.Each of us has a unique "smellprint" that is equally appealing to all others
--body odor is relative; we smell best to a person whose genetically based immunity to disease differs
most from our own
4.The notion that animal senses play a role in personal attraction diminishes our humanity
--scientific understanding of the role of smell in our lives leads only to conclusions that our tastes and
emotions are highly sophisticated, the product of many inputs
7. How is perfumed related to perceptions (e.g., women who wear lots of perfume are perceived as...)? -
Answer --quantity of perfume applied was related to perceptions of both social attraction and
competence in a negative manner: positive perceptions were highest in the "no perfume" condition and
steadily decreased until they were lowest n the "high perfume" condition
-diff pattern for physical attraction:
-highest rating were in the "low perfume" condition rather than the "no perfume" condition; latter
finding seemed to be driven by men's responses
-pattern of men's and women's responses were similar except for the finding that men's ratings of phys
attractiveness peaked in low perfume condition, while women's respondent's scores generally fell more
directly from no perfume condition to high condition
-increasing applications of perfume resulted in steadily increasing neg evaluations of interviewers social
and phys attractiveness and competence
3. What incorrect cues do police officers tend to focus on when attempting to detect deception? -
Answer --detectives were strongly influenced by the subjects social anxiety and public self consciousness
(ability to become aware of another's perspective and to act from that perspective); those who have
strong sense of this will seem more credible
