Responding to Emotion Flashcards
If emotion expressions are adaptations, what is their function?
For many expressions, apparent links between action tendency / function of emotion and facial movements of expression.
Anger:
Action tendency = attack; facial movement looks like a snarl
Disgust:
Need to avoid or expel toxic substances; facial movement closes nasal passage and pushes objects out of mouth
Fear:
Need to detect threats in environment and signal fear to group members; wide eyes are recognisable and increase visual field; flared nostrils increase air capacity
Facial expressions:
reflect both internal feeling states and the social intentions / motivations of the expresser
Prosody:
refers to the nonverbal components of speech that convey information, particularly emotion information.
To a large extent, affective signals in the voice are uncontrollable.
Voice expression:
Voice primarily conveys the degree to which a person is physiologically aroused, but nothing about specific emotion states (Bachorowshki, 1999).
E.g. anger and joy involve increases in pitch and loudness (both high-arousal states)
Key acoustic properties of emotion:
- Pitch
- Loudness
- Rhythm and tempo
- Breathiness
- Nasality
- Glottal excitation (e.g., different vowels and consonants)
Attention refers to
a cluster of processes that focuses awareness on to a particular part of your experience.
Emotional faces capture attention…
- Particularly those that communicate threat (anger, fear expressions)
- Even when presentation is brief (20 ms)
Broaden-and-build theory predicted…
broadening of attention during positive emotion state
Fredrickson & Branigan, 2005
Whole-person emotion expression is…
contributed to by face, the body and voice emotion signals
Emotions hold…
our attention, making it more difficult to disengage from object
Suggested level of arousal, rather than valence, determines…
narrowing of attentional scope
Weapon focus
(Loftus et al., 1987)
Witnesses to a crim are in a state of heightened arousal, and scope of attention narrows to threatening stimulus (like a gun). This reduces the amount of extraneous information they can take in, like an accurate description of the suspect’s clothing.
