Cognitive psychology Flashcards
Empiricism
The theory that all knowledge is derived from sense-experience. Stimulated by the rise of experimental science, it developed in the 17th and 18th centuries, expounded in particular by John Locke, George Berkeley, and David Hume.
Nativism
The theory or doctrine that concepts, mental capacities, and mental structures are innate rather than acquired or learned. Championed by Descartes and Kant
Soma and its size
Neuron body, 5-100 micrometers
Terminal bouton game to dendrite size
10-50 nanometers
Pyramidal cell
Soma looks like a diamond with one axon and maybe a few branches protruding one way and one branch with many dendrite branches protruding the other way.
Cerebellar Purkinje cell
Triangular soma with a mess of dentrites stemming from it almost in a square. One axon going the other direction.
Motor cell
Round soma with many dendrites stemming from various parts of the circle. One myelinated axon that connects to the muscle
Sensory cell
Soma between receptor cell and the brain. Axon between receptor cell and soma. All is myelinated.
Coarse coding
The activation of broad semantic fields that can include multiple word meanings and a variety of features, including those peripheral to a word’s core meaning. In neuroscience, it is when a single neuron responds to a range of events.
Cortical minicolumn
a vertical column through the cortical layers of the brain, comprising perhaps 80–120 neurons. Might be related to extreme localization
Hemodynamic response
Allows the rapid delivery of blood to active neuronal tissues. Since higher processes in the brain occur almost constantly, cerebral blood flow is essential for the maintenance of neurons, astrocytes, and other cells of the brain.
Near-infared spectroscopy
NIRS can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., in branches of cognitive psychology as a partial replacement for fMRI techniques.[9] NIRS can be used on infants, and NIRS is much more portable than fMRI machines, even wireless instrumentation is available, which enables investigations in freely moving subjects.[10][11] However, NIRS cannot fully replace fMRI because it can only be used to scan cortical tissue, where fMRI can be used to measure activation throughout the brain. Special public domain statistical toolboxes for analysis of stand alone and combined NIRS/MRI measurement have been developed[12] (NIRS-SPM).
What is BOLD
Blood Oxygen Level Dependent response used in reading fMRIs
Marr’s computational level
Where classic cognitive models fall, even if it includes ERP and fMRI evidence.
It is constrained by the goals, the dimensions of the environment and behavior. It’s expressed as an equation.
Marr’s process level
Representation and algorithm stage. Converts input and output into a function. Unconstrained because there can be many algorithms to reach the same conclusion. There can be an optimal algorithm, but the brain doesn’t always behave optimally.
Marr’s implementation level
Neuroscience. It has massive parameters
Appreciative agnosia
Apperceptive agnosia is failure in recognition that is due to a failure of perception.
Associate agnosia
associative agnosia is a type of agnosia where perception occurs but recognition still does not occur.
