Psych 203 Midterm I || with 100% Error-free Answers.
Primacy effect correct answers tendency to remember words at the beginning of a list especially
well
recall accuracy correct answers Memory recall decreases after a longer interval.
(Behavioral Research method)
recency effect correct answers tendency to remember words at the end of a list especially well
Recognition accuracy correct answers E.g. face recognition. Used a distractor.
(Behavioral Research Method)
Priming correct answers Occurs when processing of a stimulus is facilitated by the prior
presentation of a related stimulus.
Congruent (priming) correct answers if the target is a tool, the prime is another tool.
Incongruent (priming) correct answers If the target is a face, the prime is a tool
Eye tracking correct answers Behavioral Research Method: behavior of eye
Divided visual field correct answers Behavioral Research Method: useful for split brain patients
Neuropychology correct answers Studying the damaged brain: tramatic brain injury, stroke,
lobotomy.
E.g. Phineas Gage
Resolution correct answers Ability to tell
two points in space apart
two points in time apart
High spatial resolution correct answers fine detail
High temporal resolution correct answers fast detail
Spatial frequency correct answers Vision touch: measured in cycles/unit of space
Temporal frequency correct answers Hearing, touch: measure in cycles/unit of time like Hertz
Electrophysiology: single neuron ("unit") recording correct answers Eavesdropping on a cell
Learn about information cells are representing and processing
Electrophysiology: (EEG&ERP) correct answers Extracranial
Learn about person's arousal state
Learn about the timing of neural events
, Poor spatial resolution
Electrophysiology: Electro-corti-cography (ECoG) correct answers Invasive = electrical field
potentials recorded directly from the surface of depths of brain
Good spatial and temporal resolution
Capable of stimulation and recording.
Electrophysiology: Magnetoencephalography correct answers Measures magnetic fields
produced by electrical currents in brain.
Good temporal and fair spatial resolution
Requires "SQUID" array
Neuroimaging: Magnetic Resonance Imaging correct answers Good spatial resolution
Observe anatomical and structural images
Poor temporal resolution
Neuroimaging: Diffusion tensor imaging (DTI) correct answers Special application of MRI
Reveals white matter tracts within the brain
same spatial resolution as MRI
Poor temporal resolution
Neuroimaging: Functional Magnetic Resonance Imaging correct answers Measures increases and
decreases in blood flow
Low spatial resolution
better temporal resolution
Blood oxygenation level dependent
Manipulation/perturbation: Transcranial Magnetic Stimulation (TMS) correct answers Electric
currents flow and sum at their point of intersection.
Strong magnetic field
Alters the electrophysiological properties of the underlying cortical neurons.
temporal resolution = milliseconds
spatial resolution = millimeters
Manipulation/perturbation: Transcranial Direct Current Stimulation correct answers Two
electrodes on head that can induce transient disruption of brain actives.
Inexpensive and painless.
Positron Emission Tomography (PET) correct answers Requires injection of radioactive isotopes
to measure changes in cerebral blood flow
Rare
Spatial resolution is poorer than MRI
Do not require strong magnetic field
Interactionism correct answers Rene Descartes
Form of dualism
