IB SEHS EXAM UPDATED ACTUAL
Exam Questions and CORRECT Answers
Feedback - CORRECT ANSWER - describes information resulting from an action or
response
Evaluate the concept of the psychological refractory period (PRP) - CORRECT
ANSWER - The period of time during which the response to a second stimulus is
significantly slowed because a first stimulus is still being processed.
The processing of s2 cannot take place until processing of s1 is complete.
Hick's Law - CORRECT ANSWER - as you double the number of stimulus-response
couplings there is a linear increase in response time
Response Time = - CORRECT ANSWER - Reaction Time + Movement Time
Response Time - CORRECT ANSWER - the time from the introduction of a stimulus to
the completion of the action required to deal with the situation
Reaction time - CORRECT ANSWER - time elapsed for the onset of a stimulus to the start
of the response
Movement time: - CORRECT ANSWER - time it takes to carry out the motor aspect of
the performance
Compare different methods of memory improvement. - CORRECT ANSWER - Rehearsal:
the more a memory is rehearsed, the more likely it is that it will be remembered.
Coding: crucial first step to creating a new memory. It allows the received item of interest to be
converted into a construct that can be stored and then recalled later from short-term or long-term
memory
Brevity: the quicker a process is learned, the more likely it is to be remembered.

Clarity: initially you don't always know what to respond to; the coach/teacher can begin with
simple approach and build on the information; help you focus.
Chunking: pieces of information are grouped together then remembered as one piece of
information.
Discuss the relationship between selective attention and memory. - CORRECT
ANSWER - Selective attention (SA) operated in the short-term sensory store (STSS). Only
the relevant information is passed to the short-term memory (STM) where it is held for several
seconds. SA ensures that information overload does not occur and prevents confusion, as the
brain would not be able to cope with streams of information. A filtering mechanism operates,
which separates the relevant information so that athletes concentrate on one cue or stimulus (for
example, the ball, position of player in a game of tennis) to the exclusion of others. SA is very
important when accuracy or fast responses are required and can be improved by learning through
past experiences and interaction with long-term memory.
Selective attention - CORRECT ANSWER - the individual focusing on relevant
information while ignoring irrelevant information. Unselected stimuli are filtered out but selected
stimuli are compared to information stored in LTM. This allows us to make decisions on what
action to take.
Outline the components associated with sensory input. - CORRECT ANSWER -
Exteroceptors: provide information from outside the body. The main Exteroceptors involved in
sensation with regard to sport are vision and audition.
Proprioceptors: Proprioception means "sense of self". In the limbs, the proprioceptors are sensors
that provide information about joint angle, muscle length, and muscle tension, which is
integrated to give information about the position of the limb in space.
Interceptors: provide information from within the body, information about body position, and the
position of limbs. The main interceptors involved in sport are the vestibular apparatus, which
provided the information about balance; and joint receptors, muscle spindles, and Golgi tendon
organs, which provide information about limb positions. Receptors sensing blood pressure,
plasma osmolality, blood glucose concentration or the degree of stretching of the urinary
bladder.
Describe Welford's model of information processing. - CORRECT ANSWER - -Take in
information through our senses and temporarily store all of these inputs prior to sorting them out
• The inputs that are seen as relevant to the decision are then stored in the short-term memory
