Cognitive Psychology Flashcards
behaviourist
one who adheres to the perspective in psychology that focuses on observable behaviour
biological perspective
perspective in psychology that describes cognition according to the mechanisms of the brain
embodied cognition
a perspective in psychology that cognition serves for bodily interaction with the environment
representationalist
one who adheres to the perspective in psychology that concepts can be represented in the mind
scientific method
a method of gaining knowledge in a field that relies on observations of phenomena and which allows for tests of hypotheses about those phenomena
empiricism
the principle that the key to understanding new things is through systematic observation
determinism
the principle that behaviours have underlying causes and that understanding involves identification of what these causes are and how they are related to the behaviour of interest
testability
the principle that theories must be stated in ways that allow them to be evaluated through observation
parsimony
the principle of preferring simple explanations over more complex ones
dependent variable
the behaviour that is measured in a research study
independent variable
a factor in an experiment that is manipulated by the researcher (e.g.: randomly assigning subjects to a group in the experiment)
case study
a research study that focuses on intensive analyses of a single individual or more broadly on a single observation unit
correlational study
a research study that examines relationships between measure variables
experimental study
a research study that examines causal relationships between variables
the absolute threshold
the smallest amount of stimulus energy necessary to detect a stimulus. For example, the smallest amount of light energy that enables a person to just barely detect a flash of light would be the absolute threshold for seeing that light.
the difference threshold
(called DL from the German ‘Differenze Limen’, which is translated as ‘difference threshold’) is the smallest difference between two stimuli that a person can detect.
sensory system
a system that receives and processes input from stimuli in the environment
distal stimulus
stimulus in the environment
proximal stimulus
stimulus as it is represented in the mind
bottom-up processing
understanding the environment through basic feature identification and processing
top-down processing
understanding the environment through global knowledge of the environment and its principles
theory of unconscious inference
the idea that we make unconscious inferences about the world when we perceive it
Gestalt Psychology
a perspective in psychology that focuses on how organisational principles allow us to perceive and understand the environment
Principle of Pragnanz
an organisational principle that allows for the simplest interpretation of the environment
affordances
behaviours that are possible in a given environment
ventral pathway
the pathway in the brain that processes “what” information about the environment
