IB SEHS EXAM Questions With Correct
Answers

Feedback - answer✔✔describes information resulting from an action or response

Evaluate the concept of the psychological refractory period (PRP) - 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 - answer✔✔as you double the number of stimulus-response couplings there is a
linear increase in response time

Response Time = - answer✔✔Reaction Time + Movement Time

Response Time - answer✔✔the time from the introduction of a stimulus to the completion of the
action required to deal with the situation

Reaction time - answer✔✔time elapsed for the onset of a stimulus to the start of the response

Movement time: - answer✔✔time it takes to carry out the motor aspect of the performance

Compare different methods of memory improvement. - 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. - 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 - 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. - 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. - 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
• A decision is made by comparing the information in the short-term memory with previous
experiences stored in the long-term memory
• With reference to the long term memory for the required action the decision is carried out
• The action and the results are stored for future reference
• The whole process then begins again

Describe a simple model of information processing. - answer✔✔Information processing is the
system by which we take information from our surrounding environment, use it to make a
decision and then produce a response: input-decision-making-output.
All the approaches are only models. Input and output are assessable/observable, but the decision-
making process can only be speculation.
(Input -> Decision Making -> Output)
