Perception and Cognition Flashcards
Cognitive Psychology
understanding human cognition through observation of behaviour during performance on cognitive tasks
Cognitive neuroscience
using behaviour and the brain to understand human cognition
Cognitive neuropsychology
studying brain damaged patients to understand human cognition in general
provides evidence of brain cognition linkages
computational cognitive psychology
artificial inteligence
computational modelling
cognitive architectures
using computational models ( algorithims) to understand cognition
many models fail to make new theoretica predictions
fail to generalise
a
Sequencia funcionamento
Stimulus- Attention-Perception-thought process-decision-Response or Action
Bottom -up processing
diretamente influenciado por estímulos do ambiente ( externos)
Top-down processing
influenciado por fatores internos (knowloge, expectations)
Parallel Processing
-more than one process at the same time
-comum com tarefas praticadas
Cascade processing
-um tipo de parallel processing
-um processo comeca antes do anterior terminar
-pessoas formam hipóteses antes mesmo de terminar de ler todas as letras
Stoop Effect
interfering signals in your brain that compete for your attention
PRP Paradigm (Psychological Refractory Period)
2 stimulus são apresentados em rápida sucessão e cada um requer uma resposta rápida.
-Perceptual analyses pode ser feita ao mm tempo
-Response selection/ Decision tem que ser feita uma de cada vez.
-Response processing vem por ultimo (da primeira tarefa primeiro, depois da segunda)
Cognitive psychology STRENGTHS AND LIMITATIONS
S_ primeiro systematic approach
levou a inúmeras teorias e tasks adopted by other approaches
very flexible: can be applied in any aspect of cognition
L_a maioria das tarefas sao impuras e lack ecological validity
indirect evidence of underlying processes
theories are often vague and hard to test.
