Presentation Articles Flashcards
What are the aspects and advantages of discrete emotion theories?
- There is a limited set of basic emotions that make up the entire spectrum through combination
- Expression of these basic emotions is similar across cultures
- Makes it easy to compute an output behavior from emotional states
How do emotions arise according to appraisal theory?
Via the comparison of individual needs and external demands - the person-environment relationship. This is assessed in terms of appraisal variables, which are questions like “Is this event desirable?” etc.
Why are appraisal theories sometime criticized in their psychological plausibility?
According to them, there are cognitive processes (evaluating of appraisal variables) that precede emotions. This contradicts the fast and automatic emotional responses we see in the real world.
What are the four parts to the EMA Model?
- Representation of the agent-environment relation
- Appraisal derivation process
- Emotion derivation process
- Affect Consequences
The behavioral and cognitive output of the EMA model can affect which steps in the EMA process?
- Overt behavior
- The evaluation of appraisal variables
- The perception of the agent-environment relation
What kind of emotions are difficult to model computationally?
Complex social emotions like embarrassment etc.
What are the evaluation criteria of a CRUM?
- Representational Power
- Computational Power
- Psychological Plausibility
- Neurological Plausibility
- Practical Applicability
is backpropagation supervised or unsupervised?
Supervised
Describe the neural connection between the Dentate Gyrus and the CA3.
The input from the DG excites relatively few CA3 cells (sparse input), but different patterns of activation of the DG trigger different sets of CA3 neurons
What would a computational representation of the hippocampus have to be able to do?
- Store a large number of patterns after a single presentation
- Retrieve information on the basis of partial cues
How would learning in the DG be modeled computationally?
With competitive learning
How would CA3 be represented computationally?
As an auto-associator
Competitive learning would be used to model which parts of the hippocampal system?
Dentate Gyrus and CA1
Name 3 rule-based systems
ACT
GPS
SOAR
Why do rule based systems have a higher computational power than logic systems?
Because rules don’t have to be interpreted as always true/relevant
