IB SEHS EXAM 2025 QUESTIONS
AND 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.
