Motor Learning exam 2

Extroreceptive Information

Stimulus/Info primarily arising outside the body like hearing, smell, touch, taste and vision

Vision

Information about objects moving, primary for motor skills

Interoceptive Information

Senses from within the body like proprioception and kinesthesia

Kinesthesia

Forces/motion in muscles, CHANGE in body orientation

Vestibular apparatus

located in inner ear ; info about balance, posture, and orientation

Muscle Spindle

Located in Skeletal Muscle ; sends information about muscle length to CNS

Golgi Tendon Organ

Located between muscle and tendon ; provides information about force in the muscle

Somatosensation

Combination of proprioception (interoceptive) and haptic (exteroception) info giving us our bodily sensation of touch, pain, temp and limb position

Meissner Corpuscals

Detects deforming skin

Merkel discs

located edge, where skin deformed. deep touch,

Pacinan Corpuscal

Detects pressure, vibration, detects texture, and lifting/unloading of an object

Ruffini endings

Lateral tension, stretch. this monitors slippage

Somatic Receptors

Shows how sensitive each area of our body’s skin is to touch

Motor Receptors

Shows how much organ space is detected to controlling certain voluntary muscle activity throughout our body

Ventral Stream

Located in the inferoreceptive cortex

Tau

time to contact is defined as the inverse of the rate of dilation of an image on the retina

Feature Integration theory

Automatically create “maps” —> usually shapes and colors. More distinctive the features, the quicker one can identify it

Movement Filter

allows visual attention to be directed at moving items

Temporal Occlusion

Researches are looking to see when experts detect critical info in these time series

Event Occlusion

used to determine which determine which visual info is most important for generating a correct motor skill

Visual Selective Attention

role of vision in motor skill performance in directing visual attention to environmental info that influences the performance of an action

Attentional Spotlight

selection features of interest on the feature integration map “goal directed”
