how is lying behavior studied
HOW IS LYING BEHAVIOR STUDIED?
  • FAKED LYING
    • COUNTERATTITUDINAL LIES
    • COUNTERFACTUAL LIES
  • “REAL” LYING
    • CHEATING & STEALING FORMATS
    • MOST LIES ARE NOT “MAJOR” & GENERALLY PEOPLE ARE NOT AFRAID OF BEING CAUGHT
difficulties in identifying liar behavior
DIFFICULTIES IN IDENTIFYING LIAR BEHAVIOR
  • NO SINGLE BEHAVIOR HAS BEEN FOUND TO BE ASSOCIATED WITH LYING AND NOTHING ELSE
  • DIFFERENT TYPES OF LIES (PREPARED OR NOT; LONG OR SHORT; ETC.) AND DIFFERENT MOTIVES (PROTECTING SELF; AVOIDING CONFLICT; WHITE LIES; ETC.) ARE LIKELY TO SHOW DIFFERENT BEHAVIORS
nonverbal behavior
NONVERBAL BEHAVIOR
  • INITIALLY, NONVERBAL BEHAVIOR THOUGHT TO BE THE KEY TO IDENTIFYING LIAR BEHAVIOR BECAUSE IT WAS THOUGHT TO BE OUT OF OUR AWARENESS AND CONTROL
slide6
NOW WE KNOW:
    • FACIAL MOVEMENT IS SUBJECT TO CONSIDERABLE CONTROL, BUT MICRO EXPRESSIONS, FALSE SMILES, AND POOR TIMING MAY BE CLUES TO DECEIT
    • FEET/HANDS/BODY ARE LESS UNDER CONSCIOUS CONTROL AND MAY SHOW MORE “LEAKAGE”
    • LIARS MAY BE THE LEAST CONSCIOUS OF VOCAL SIGNALS
    • ATTEMPTED CONTROL MAY RESULT IN OVERCOMPENSATION--E.G., EYE GAZE
motivational impairment process
MOTIVATIONAL IMPAIRMENT PROCESS
  • THIS IS A THEORY (SUPPORTED BY SOME RESEARCH) WHICH ARGUES THAT THE MORE IMPORTANT THE LIE TO THE LIAR, THE GREATER THE CHANCES THAT IT CAN BE DETECTED FROM NONVERBAL CUES AND THE LESS LIKELY IT CAN BE DETECTED FROM VERBAL CUES
nonverbal
NONVERBAL
  • LESS SMILING
  • FAKE SMILING (NO USE OF LOWER EYELIDS)
  • MORE SPEECH ERRORS
  • MORE HESITATIONS DURING SPEECH
  • LONGER LATENCY OF RESPONSE
  • HIGHER PITCH
other nonverbal behaviors which commonly occur
OTHER NONVERBAL BEHAVIORS WHICH COMMONLY OCCUR
  • PUPIL DILATION
  • RAPID BLINKING
  • NERVOUS MANNERISMS
  • SHRUGS
  • IDIOSYNCRATIC SIGNALS--E.G., SWALLOWING/GULPING; RED NECK; ETC.
verbal behavior
VERBAL BEHAVIOR
  • LESS CONTENT--SHORTER RESPONSE LENGTH
  • ALLNESS TERMS--E.G., ALL, EVERY, NONE, NOBODY, ALWAYS
  • FEWER VERIFIABLE REFERENTS MENTIONED--NONSPECIFIC INFORMATION; VAGUE; ABSTRACT
  • SLIPS OF THE TONGUE
lies embedded in conversational acts
LIES EMBEDDED IN CONVERSATIONAL ACTS
  • LIES WHICH FULFILL THE NEED FOR ACCEPTANCE/AGREEMENT
  • LIES WHICH DENY SELF-DEPRECATIONS
  • LIES USED TO DEFUSE ANTICIPATED REJECTIONS
general factors used in judging the possibility of deceptive verbal behavior
GENERAL FACTORS USED IN JUDGING THE POSSIBILITY OF DECEPTIVE VERBAL BEHAVIOR
  • PLAUSIBILITY
  • CONCRETENESS
  • CLARITY
  • CONSISTENCY
cognitive emotional processes associated with lies
COGNITIVE EMOTIONAL PROCESSES ASSOCIATED WITH LIES
  • LIMITED TO LIES IN WHICH THE LIAR KNOWS HE/SHE IS LYING AND PERCEIVES IMPORTANT CONSEQUENCES OF THE ACT AND IS NOT A PATHOLOGICAL LIAR
slide16
THE TWO MOST STUDIED
    • AROUSAL
    • COGNITIVE DIFFICULTY
