AND SOLUTIONS GUARANTEE A+
✔✔TMS (transcranial magnetic stimulation) - ✔✔Deactivates neurons. Able to see what
the effect is and deduce function accordingly.
✔✔Sensation - ✔✔Stimulation of a sense organ
✔✔Perception - ✔✔Organization and interpretation of senses
✔✔Transduction - ✔✔Conversion from physical signals to mental ones
✔✔Psycophysics - ✔✔Measuring strength of stimulus and our sensitivity to the
stimulus.
✔✔Absolute threshold - ✔✔Minimum intensity needed to detect a stimulus in 50% of
trials
✔✔JND (just noticable difference) - ✔✔Minimum change in the intensity to be noticed
✔✔Weber's Law - ✔✔We detect stimuli proportionally
✔✔Sensory adaption - ✔✔Prolonged stimulation decreases stimulation
✔✔Cones - ✔✔Detect color. Require light. 3 different kinds for 3 frequencies. Densely
packed in fovea
✔✔Rods - ✔✔Detect low level light. No color information. None in the fovea
✔✔Ventral Stream - ✔✔Path to temporal lobe. Responsible for recognizing the object.
✔✔Dorsal Stream - ✔✔Travels to the parietal lobe. Allows us to tell where the object is
and use it.
✔✔Visual form agnosia - ✔✔Inability to recognize objects by sight. Damage to ventral
stream
✔✔Change blindness - ✔✔When people fail to detect changes to visual details in a
scene.
✔✔Inattention blindness - ✔✔Failure to perceive objects that are not the focus of
attention.
✔✔Properties of light - ✔✔hue, brightness, saturation
, ✔✔Properties of sound - ✔✔pitch, loudness/intensity, tambre
✔✔cochlea - ✔✔fluid filled tube, rolled up. Organ for auditory transduction
✔✔basilar membrane - ✔✔structure in the inner ear that vibrates with frequencies.
✔✔4 Touch receptors - ✔✔Heavy pressure, light touch, vibration, and skin stretch
✔✔Pheremone - ✔✔Scent transmitted by another member of our species
✔✔Chemoreception - ✔✔Signal travels to olfactory bulb, very linked to emotional
centers.
✔✔Taste receptor types - ✔✔Sweet, sour, salty, bitter, umami
✔✔Phenomenology - ✔✔How things seem to the conscious person
✔✔Consciousness - ✔✔A person's subjective experience of the world and the mind
✔✔Problem of other minds - ✔✔We don't know what others actually perceive.
✔✔Experience and agency - ✔✔Experience: Ability to feel pain, pleasure, hunger,
anger, etc.
Agency: Ability for self control and planning
✔✔Mind-Body Problem - ✔✔How is the brain and body related to the mind
✔✔4 PROPERTIES OF CONSCOUSNESS - ✔✔Intentionality: Being directed towards
an object. Able to act on something in your surroundings.
Unity: Able to integrate information from all senses into one coherent whole.
Selectivity: Including some objects in your conscousness and excluding others. (cocktail
party phenomenon)
Transience: Tendency to change.
✔✔Levels of consciousness - ✔✔Minimal: Low - level sensation recognition
Full: Able to know and report mental state
Self: When attention is drawn to the self as an object
✔✔Rebound effect of thought suppression - ✔✔Tendency for a thought to occur more
frequently when attempting to suppress it. (White bear)
✔✔Ironic monitor - ✔✔Idea that the mental process that monitors errors themselves
produces them.
