1
what cues are taken into account when perceptually organizing?
depth, form, motion, constancy
2
what do binocular cues provide?
depth perception(due to retinal disparity)

Retinal disparity is defined as the way that your left eye and your right eye view slightly different images. ... Retinal disparity is important in gauging how far away objects are. The more difference (or greater disparity) between the image each eye has of the same object, the closer it is to you.
3
what is convergence?
gives depth perception based on how much eyes are turned inward
4
what do monocular cues provide?
relative size

interpositon

relative height

shading/countour

motion (through motion parallax) - things farther away move slower, closer moves faster

constancy - perception of object doesn't change even if the image cast on the retina is diferent. size constancy, shape constancy, color constancy
5
how does your inner ear adapt to loud noises?

what are the 3 elements of feature detection? what sense is it used for?
color, form, motion

Feature detection involves the perceptual discrimination of specific aspects of a given stimulus via feature detectors. Feature detectors are specific neurons that preferentially fire in response to very specific stimuli.

Feature detection occurs for all the senses but is most often described regarding vision. Feature detectors in the visual system respond to aspects of the visual stimulus, such as horizontal lines or right angles (among others). The visual system is organized such that feature detectors synapse on neurons that respond to more complex stimuli (eg, faces) localized in certain areas of the brain (eg, fusiform face area)

EXCLUSIVELY VISION

occurring together is higher than the probability of one alone (ex. Linda being a
bank teller and feminist is greater than just being a bank teller. However
statistically speaking there are more bank tellers than feminist bank tellers so it’s
more likely she is just a bank teller than a feminist + bank teller, which your
instincts might be telling you)

language and thought are both independent, but converge through
development. Eventually learn to use them at same time via socialization -
Believed children developed language through social interaction with adults who
already knew the language
235

Event-->Physiologic Response-->Interpretation-->Emotion

Interpreting the physiological signs resulting from an event

Ex2: A man, who is allergic to bees, encounters a bee. The man’s heart
beat increases, he starts sweating, and he interprets these physiological
changes as the emotion fear.

MNEMONIC: JAMES BOND - he's all about action - when an event happens - our body has ACTION happen first (physiological response) - then we interpret
254
what is the Cannon-Bard theory of emotion?
Event-->Physiologic Response+Emotion

Emotion+Physiologic response happens at same time
Ex: holding your cat (event) causes your heart rate (physiological
response) to increase and feel joy (emotion) at the same time.

mnemonic: picture a bad cannon splitting a cannonball into two (simultaneous)
255
What is the Schacter-Singer theory of emotion?
Event-> PR + Identify reason for the situation
(PR) (consciously)-> Emotion

Ex: Holding your cat (event)-> Physiological response of increase HR/or
changes in NT level-> label the situation and identify reason for
physiological response and event (This is really nice, I like holding my cat,
this makes me happy)-> emotion (Happy)

Requires identifying reason for response

imagine a singer - doesn't know their voice is good - when she finished everyone is clapping for her. event first, which leads to a physiological arousal (clapping), and then she interpets the clapping and realizes that shes a good singer (labeling) then experiences the emotion
256
what is the Lazarus theory of emotion? and other name
Event-->label event(as good\/bad)-->emotion+physiologic response

Requires labeling of event before experiencing emotion and physiologic response at same time

Ex. Event (holding cat)-> labeling situation as good->emotion (joy) + physiological response.

appraisal and the secondary appraisal.
261
what is the primary appraisal of stress?
Initial assessment of stressor. Can be irrelevant, benign/helpful, or negative. If negative move to secondary appraisal. Nothing to do with intensity of it, just whether its negative or not
262
what is the secondary appraisal of stress?
evaluation of your ability to cope with the situation. Determine intensity and risk of sressor. Based on Harm, threat, and challenge of stressor
263

decreased reflexive response to stimulation (lower motor neuron sign)
279
what are the components of the muscle stretch reflex?
afferent (stimulus), efferent (response).

causes a muscle to contact after it’s stretched, as a protective response

Somatosensory neurons (afferent) in muscle spindles form excitatory synapse in
spinal cord with another neuron in the spinal cord, which sends axon out back to
same muscle that was stretched, and excite skeletal muscle cells to contract –
lower motor neurons (efferent)

medulla, pons, midbrain, reticular formation. basic functions like HR and RR. connects cerebellum to cerebral cortex and spinal cord
298
what is the function of the cerebellum?
fine motor control/voluntary movement. proprioception

The cerebellum is critical for motor learning, which occurs whenever an organism repeatedly practices a motor task, such as swimming, driving, or speaking. Motor learning is the foundation for procedural memory, the acquisition of which relies heavily on the cerebellum. Because the mice were tested in the Morris Water Maze each day for one week, the cerebellum would be involved in motor learning of this skill.

The cerebellum is also responsible for integrating information from the visual, vestibular, and somatosensory systems to maintain balance and posture, coordinate complex movements requiring multiple muscles, and control precision of fine motor movements. The cerebellum also receives feedback from the body regarding the position of body parts in space and relative to each other (proprioception)

FRONTAL LOBE IS VOLUNTARY MOVEMENT NOT MOTOR COORDINATION YOU IDIOT
