Question 1

In general, visual information is stored for _____________ seconds while auditory information is stored for _________ seconds&#10;A)2: 3&#10;B)3: 2&#10;C)2: 10&#10;D)2: 10.&#10;

Accepted Answer

In general, visual information is stored for 2 seconds while auditory information is stored for 3 seconds .
Key Takeaway: Sensory memory is a short lived memory of a sensory stimuli after it has ceased. Auditory information is stored for 3 seconds while visual information is approximately 2 seconds. Sensory memory does not need to be long as the sensory receptors send the information through neurotransmitters to the brain where it is interpreted. The short memory also allows for new stimuli to be received and processed.

Question 2

Teenagers with borderline personality disorder are much more likely to_____________.&#10;A)take offense to harmless comments on their political views&#10;B)irrational fears of presenting information to large groups of people&#10;C)have difficult and unstable relationships with most people in their lives&#10;D)hold extremely liberal views on social and cultural issues

Accepted Answer

Teenagers with borderline personality disorder are much more likely to have difficult and unstable relationships with most people in their lives.
Key Takeaway: Borderline personality disorders are considered personality disorders listed in Cluster B of the Diagnostic and Statistical Manual V (DSM-V). This disorder is usually identified early during adolescence or even earlier. Sufferers tend to have fragmented and volatile relationships with their friends, family, and teachers. They show fears of abandonment and will exhibit angry outbursts and an unstable mood.

Question 3

Sensory (afferent) neurons perform what main function in the nervous system?&#10;A)Transmit nerve impulses from one neuron to another&#10;B)Transmit nerve impulses from effector sites to the spinal cord and brain&#10;C)Transmit nerve impulses from the neurolemma to the myelin sheath&#10;D)Transmit nerve impulses from the brain and spinal cord to the effector sites

Accepted Answer

Sensory neurons transmit nerve impulses from effector sites, such as muscles and organs, via receptors to the spinal cord and brain. An example of this is when touching a hot object, the signal of the sensation of heat is transmitted from sensory neurons to the brain.

Question 4

Which of the following sensory receptors responds to touch and pressure?&#10;A)Chemoreceptors&#10;B)Mechanoreceptors&#10;C)Nociceptors&#10;D)Fibroreceptors

Accepted Answer

Mechanoreceptors respond to touch and pressure. These receptors of mechanical force are significant to the fitness professional because they sense distortion in tissues during all forms of motion, such as the stretching of tendons and ligaments through exercise.

Question 5

Sensorimotor integration is the nervous systems ability to perform what function?&#10;A)Interpret sensory stimulus in order to execute appropriate motor response&#10;B)Integrate the kinetic chain into the nervous system's response&#10;C)Determine the efficiency of a muscle movement&#10;D)Produce enough force to affect a rotary motion

Accepted Answer

Sensorimotor integration is the nervous systems ability to interpret sensory stimulus in order to execute appropriate motor response. This is vital to the trainer providing proper guidance on form and function of exercises in order for the client to learn and train them properly and achieve positive results. If trained using improper exercise technique, the client will continue to perform that in that manner, and develop muscular imbalance or dysfunction.

Question 6

What is the official currency of Australia?&#10;A)Australian rupiah&#10;B)Australian pound&#10;C)Australian dollar&#10;D)Australian kina

Accepted Answer

The Australian dollar is the currency of Australia. It is linked with the kina, the official currency of Papua New Guinea. The fractional unit of the Australian dollar is also the cent. They do not have a penny and do use $1 and $2 coins.

Question 7

Why is there a discrepancy between long-term and short-term effects of a change in demand?&#10;A)The market is slow to understand most changes.&#10;B)The market waits to see if the change is permanent.&#10;C)Equilibrium situations always take time to settle down.&#10;D)There is a cost associated with adapting to the market.

Accepted Answer

Short-term and long-term effects are different because there is a cost associated with adjusting to the market. For example, if a farmer must choose between growing corn or wheat, he or she will check prices before buying seeds. But a farmer who has already bought seeds would face a large loss by throwing them out and buying seeds for a different crop.
