Module 1 Flashcards
Most complex computer in the known universe
Brain
Cognition
Sum of mental activities resulting in the acquisition of information from the environment, processing this information, and using it to make a behavioral decision
3 steps involved in cognition
Acquisition, processing, behavioral decision
Scientific research that is concerned with understanding the world without a specific use in mind
Basic research
Scientific research to find an application or solution to a problem
Applied research
Human factors
Field of psychology concerned with the application of findings to the design of systems humans interact with
Artificial intelligence
Machine that can perform human-like intelligent behaviors
Type of intelligence historically missing from artificial intelligence
Flexible intelligence
What improved artificial intelligence ?
Programming the computer to learn and get better : machine learning
Large language model
Advanced machine learning algorithms that process and generate human-like text by understanding patterns in the data they’ve been trained on
Cognitive psychology
Field concerned with studying the mind through the observation of behaviors
Naturalistic observation
Observing behaviors in people’s natural environment
Cognition is primarily concerned with understanding the _____ that produce complex behaviors even though separate abilities are studied
Processes
Depressive symptoms linked to ____ decline with age (symptom of dementia)
Memory
2 parts of a hypothesis
Cause and effect
True or false : confirming a hypothesis means it is true
No, only that the theory seems effective at explaining the phenomenon in question
Phenomenon-based research
When an “effect” is discovered, and follow-up research examines the nature of the effect
_____ effect is an example of phenomenon-based research
Placebo
Example of Placebo effect from 1799
An experiment tested the effects of disease reduction from Perkins tractors, metal “disease extractors” & placebo wooden tractors – found no difference
Emotional enhancement effect (cognitive psychology of emotions)
Emotional stimuli are more easily attended to and remembered than neutral stimuli
Behavioral experiments show focal memory enhancements for ____negative/positive stimuli in an image
Negative
When we see someone with a gun, we remember their face ___less/more than when we see someone with a drink
Less
Neuroscience
Studies what parts of the brain carry out functions we see behaviorally
Amygdala activity predicts _____ for emotional but not neutral images
Memory
Computational modeling
Building and modelling the mind-brain connection
Computational models use boxes and arrows to build artificial agents to try to simulate ______
Emotions
If computational models emotional circuits lead to the same effects we see in humans, we can know …
The circuits driving emotions in humans
What cognitive approach is this ? “If we really understand how something works; we should be able to build it”
Computer modelling / AI
