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
-detectives interpreted behavior displayed by people who had less public self consciousness and
more social anxiety not as a form of natural behavior but as deceptive behavior
-detectives strongly influenced by confederates clothing
-detectives associated less smiling and increase of hand and arm movements with deception,
even though previous research has indicated that a decrease not an increase of hand and arm
movements indicates deception and smiling doesn't provide reliable info about deception
2. How is status/power/dominance related to chronemics? (i.e. how will dominant people use
chronemics) - Answer -chronemics=examines use and structure of time and various meanings
attached to it
-Waiting-time:
-act of making subordinate wait can be used to assert dominance; waiting time decreases as
status increases
-Talk-time and Interaction Management:
-dominant individuals will talk more and will hold the floor for a greater proportion of the total
time than will a less dominant person
-high status persons cmn more frequently and speak longer in group discussion
-high-status/dominant interrupt more frequently
-subordinates response latencies are shorter; superior may take time to answer
