Lab 2 Flashcards
What is Lab 2 About?
Sensory and Motor system integration
Nervous System Integration
The generation of a motor output based on the sum of the sensory inputs.
How is much of the integration done within the nervous system?
Through reflex arcs
what reflex does not require the brain?
The Patellar reflex
Why is it that animals with larger brains can learn more quickly?
They have more inter neurons and neuronal connections.
Reaction time:
Start of a signal to the response
What factors influence reaction time
- ) Signal complexity
- ) strength
- )duration
Three ways in which the sensory system stimulated affects reaction time:
- ) There are differences in afferent conduction times between sensory systems.
- ) Some sensory systems can change instantly while others change more slowly.
- ) Certain sensory systems are more sensitive.
Visual Motor Learning
Increasing the accuracy, speed and coordination of tasks involving hand-eye coordination the more often you perform them.
Calculation for Standard error of the mean
SEM= STDEV/SQRTn
Can you calculate a standared error for the students?
no
What does the SEM mean?
quantifies how much the reaction times vary among the students
A 95% confidence interval represents…
the range of values that you can expect to contain the true mean of the population.
What does a smaller SEM mean?
A smaller SEM signifies a smaller amount of variation in the population as a whole.
What does it mean if your data lies within the 95% CI calculated for the class data?
Your data will not likely be statisitically different from the population as a whole.
