according to recent research discussed in class, the gender gap in men’s and women’s world record performances has been stable(at about 10%) since what year?
1983
what is the name specifically given to the scientific approach used to study individual differences?
differential approach
***experimental approach can show causality, differential cannot
according to the research published in the journal Pediatrics and discussed in class, what is the correlation coefficient between IQ and motor coordination in children?
.44 (weak/moderate correlation)
between the Theory of General Motor Ability and the Specificity Hypothesis, which is more recent?
specificity hypothesis
who is responsible for your abilities?
your parents
what correlation coefficient indicates no association whatsoever between variables?
zero
the ________________ of a correlation determines the extent to which the correlation can be used to predict one variable from knowledge of another variable
strength
true or false: if you found a correlation coefficient of +0.82 between arm length and ball throwing distance, you would be able to conclude that arm length affects throwing distance.
false
correlation coefficients between _____________ and ______________ are typically considered strong
0.7 and 1
the stronger the correlation, between two motor tasks, the ______________ abilities are likely shared by the tasks.
more
in science, theory yields predictions. these predictions form the basis of __________________
hypothesis
true or false: a person’s potential for skilled performance is easily predicted
false
under ideal conditions, the ____________________ nervous system can regenerate somewhat following an injury
peripheral
true or false: any spinal cord injury that occurs at the lumbar level will be an incomplete injury
false
what 3 elements are critical to performance of any motor skill?
perceiving, deciding, producing
what 2 things determines functional impairment of SCI?
completeness and location
what does injury of the cervical spine cause?
tetraplegia
neurons that send info out into the spinal cord
motor/efferent
neurons that receive info into the brain
sensory/afferent
how does the brain/spine interface(digital bridge) work to restore movement to the paraplegic man?
2 implants are placed into the brain and extended into the spinal cord and 2 implants are placed there as well; electrodes in brain send info to spinal cord electrodes
what neurotransmitter plays a role in SIDS?
serotonin
why do pediatricians advise babies to sleep on their backs?
does not obstruct breathing
where do spinal nerves serving the legs exit/enter the spinal cord? arms?
lumbar spine; cervical spine
where in your brain are respiration, BP, and HR regulated?
