The question you should ask yourself is do you really want to be with someone who does not respect your feelings. If they can't accept how you feel, then that will cause a lot of problems later on. In a good relationship you must work together and be on the same page.

__________ reaction time is a stimulus response. Instant Simple Complex Automatic
MrRa [10]

Answer:

The correct answer is option (3) Complex.

Explanation:

The complex reaction time is a stimulus response. The complex reaction time may be defined as the latency that exists between the variable response and the variable stimulus.  It decides the arrival of the stimulus and the time required to generate the response. The fatigue and type of stimulus may affect the reaction time.

Further explanation:

  • Reaction time may be defined as the time required for the onset of any stimuli and the emission response of an organism.
  • Simple reaction time is the only time that is taken to react towards a stimuli.
  • The reaction time can be affected by various factors like age, gender, sex, race, stimulus type, stimulus intensity and psychological stability.  
  • Complex reaction time takes more time than the simple reaction time as they store the information for longer time.  
  • The information processing and transmission of the information of a particular stimuli can be measured in terms of the reaction time.
  • The visual stimuli, auditory stimuli strength and its generation time response can be calculated by the reaction time.
