To what extent do cognitive and biological factors interact in emotion? (22)

To What Extent (22) – Consider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument.

Components in Emotion

Biological Interaction

Neurobiological contribution to emotion (Theorist: LeDoux)
Two routes from sensory stimulus to Amygdala
1. Fast route – Thalamus to Amygdala

2. Slow route – Thalamus > Cortex > Hippocampus > Amygdala

LeDoux – Fear in rats experiment (Biological factors in emotion)
[A] Investigate the role of the amygdala.
[P]
  • Rats were conditioned to feel fear when they hear the sound of a bell.
  • Assumption that the brian has made a connection between the bell and fear.
  • LeDoux lesioned the rats to find out which part of the brain made the connection between the bell and fear.
[F]
  • After several lesions, they removed the Auditory Thalamus.
  • The rats did not show respond to the bell with fear anymore.
  • In further studies, they found out that lesions on one site of the amygdala was able to stop blood pressure from rising.
[C]
  • This shows that there are biological interactions with emotions.
[E]
  • Unethical study
  • Induced feat in subjects, caused mental harm.
  • Performed lesioning on subjects, cause physical harm.
  • Subjects did not have rights to withdraw.


Cognitive Interaction

Theory of Appraisal (Theorist: Lazarus)

Spiesman et al. – Audio track interfering with emotion
[A] Prove the Theory of Appraisal can interfere with emotion.
[P]
  • Participants were shown a documentary of an unpleasant traditional ritual.
  • There were three groups of participants.
  • Group 1: Trauma group
  • They were shown the documentary with a soundtrack that emphasized the pain.
  • Group 2: Denial group
  • They were shown the documentary with a soundtrack which suggested that the ritual was joyful and happy.
  • Group 3: Intellectualisation group
  • They were shown the documentary with a soundtrack that gave an anthropological interpretation of the ritual.
[F]
  • Participants reacted more emotionally in the Trauma group when compared with the other two.
  • Because they evaluated the situation (painful soundtrack).
  • Thought it was appropriate to display negative emotions because situation showed potential harm.
[C]
  • Shows that through appraising the situation, different emotions can be displayed with the same stimuli.
  • Hence showing the Theory of Appraisal (cognition) can interfere with emotion.
[E]
  • Ecological validity: Low, lab conditions.
  • Controlled environment, removes confounding variable.


Both Cognitive and Biological Interaction

Two Factor Theory of Emotion – Schachter & Singer

Schachter &amp Singer – Injection study (Two Factor Theory of Emotion)
[A] Show that both cognition and biological factors interact with emotion.
[P]
  • 184 male college students participated in the experiment. They were taken to a private room.
  • The experimenter told them the aim of the experiment was to see “the effect of vitamin injection on visual skills”.
  • Deception: In actual fact the aim of the experiment was to test the Two Factor Theory of Emotion.
  • The participants were given either a placebo shot (with no side effects) or an adrenalin shot.
  • The effects was increased heart rates, blood pressure, blood sugar level and respiration.
  • The effects started showing at 3 minutes and lasted for 10 minutes to an hour.
  • Participants were put into one of the 4 experimental conditions.
  • 1. Adrenalin ignorant – participants with adrenalin were not told of the effects.

    2. Adrenalin informed – participants were informed with the side effects so they were prepared.

    3. Adrenalin misinformed – participants were not informed with the true side effects.

    4. Control – placebo injection without being told what side effects to expect.

  • Participants were then assigned either
  • Euphoria (feeling of happy) condition – Assistant in the waiting room carried out silly actions to entertain participants.
  • Anger condition – Assistant in the waiting room annoyed the participant.
  • Researchers observed through one-way mirror.
  • Participants filled in a self appraisal form.
[F]
  • Euphoria condition
  • Misinformed participants were feeling happier than all other groups.
  • Ignorant participants were the second happiest.
  • Anger condition
  • Ignorant participants felt the angriest.
  • Placebo participants felt the second angriest.
[C]
  • Participants were more influenced by the assistant because they had no explanation for the emotion high.
  • Leads to a wrong labeling of the physiological responses.
  • Supports the Two Factor Theory of Emotion.
  • Physiological arousal in different emotion is entirely the same.
  • We label our arousal according to cognition.
  • Cannot fully evaluate the feeling of emotional arousal.
  • Leading to misattribution
  • Influenced by surrounding situation.
[E]
  • Observations and self appraisal of emotion was subjective.
  • Measurements were rudimentary, only pulse was measured.
  • Low in ecologically validity
  • Lab experiment, unlikely to have a sudden emotional arousal.
  • Emotion arousal might be caused by external stimuli (i.e. the other way around).
  • Unethical: Induced anger and aggression in participants.
