Pay Attention
This occurs when intentional processing inhibits or prevents the processing of a critical sensory event.
Inattention blindness
MT= a + b[Log2(2A/W)
Fitts Law
In skeletal muscle near insertion of tendon
Detect changes in muscle tension (i.e. force)
Poor detectors of muscle length changes
Golgi-Tendon Organs (GTO)
What three tasks make up the KTK movement battery?
Lateral Jumping
Platform
Balance Beam
When writing methods and results sections of research papers, this "point of view" should always be used.
Third-person
Types of Attentional Interference include Structural and Capacity Interference. This type of interference is defined as Physical or neurological structures are the source of the impairment.
Structural interference:
describes the relationship between movement time, movement amplitude, and target width in aiming movements that use a combination of open- and closed-loop control.
Fitts Law
General term for actions involving reaching for and grasping objects
Prehension
What is a perfect score on the Balance Beam portion of the KTK?
72
Name the test:
Participants start with toes at the edges of the zero-distance mark. Participants will jump forward as far as possible landing on both feet. The distance jumped will be measured in centimeters and participants will return to starting position. Performance of each trial will be videotaped and jump distance will be normalized to a percent of standing height.
Standing Long Jump
According to Kahneman (1973) perceptual narrowing includes increased arousal causes __________ of the attentional focus, with progressive elimination of input from irrelevant sources.
narrowing
Give a real world example of Fitts Law in action. Simply name a device or invention that is based on the relationship that Fitts described
Mouse
Prosthesis
Pop-up menus opened faster than pull-down menus (less distance to go)
Pie-menu vs. linear menu
Keyboard design
cockpit design
etc
•Motor skills that require simultaneous use of two arms
•May require two arms to move with the same or different spatial and/or temporal characteristics
Bi-manual Coordination
Does the size of the platform effect the performance test?
no: a 25cm or 30cm platform did not differ in performance
What does TGMD stand for
Test of gross motor development
The ________ shows how the brain deals with conflicting information. It is interference in the completion of a task caused by one area of the brain dominating and inhibiting the response of other functional areas.
Stroop effect
What is the relationship between how much force you produce, and the variability of that force
Many motor abilities are highly related and can be grouped as a singular, global motor ability
General Motor Ability Hypothesis
The Körperkoordinationstest für Kinder (KTK) is German test battery developed by _(authors name(s)____. In 2007, the same authors published a reworked version of the manual. The test battery aims to evaluate the level of overall body coordination in children (aged 5y,0m to 14y,11m) by means of four gross motor subtests:
Kiphard and Schilling in 1974
Participants will start lying on their back with their hands by their side. Their feet should be in line with the strip of tape placed 18 inches from the wall. No instructions will be given to the participant on how to stand. The participant will be instructed when given the “go” command they are to stand as fast as possible and touch the designated spot on the wall in front of them. The participant will complete five trials.
Supine to stand
We’ve all experienced it, and drinks are not required. All it takes is a room full of people, with many conversations taking place at the same time. This creates a noisy environment of simultaneous talk-talk-talk, yet somehow amidst the hubbub, we are able to pick out interesting conversations nearby, ignoring the rest as background noise.
The Cocktail Party Effect
The hardest thrown baseball in MLB was clocked at 105.5 miles per hour (twice). What position did these players play?
Outfield (Center Field)
•A general trait or capacity of a person
•Relatively enduring characteristic
•A determinant of a person’s achievement potential for the performance of specific skills
Ability
differential rotation is indicative of what level of forceful throwing?
highest: level 4
