If I notice that Heng and Yolanda are often together and I "fill in" my inference that they are now lovers, then I am illustrating the concept of perception called

Closure

Explanation:

Perception can simply be defined as the way or means in which people organize and interpret their sensory impressions so as  give their environment a meaning.

in closure, when we see an incomplet image, data or information or when given incomplete information, we want  to seek completion thereby  filling in bits which do not actually exist.  In doing that we may have fill it up with the wrong or right information. example is  when we see or we were given visual images to view,  that is we  include the extension of lines to form an unbroken outline of an object. most times  we read meaning to what we see and run into conclusions that are not really real. Closure is important because it gives the parties the opportunity to own their part

Most times,  when you see an image that has missing parts, your brain will fill in the blanks and make a complete image so you can still recognize the pattern.

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.

chronological thinking is an indispensable tool to structure a historical narrative and to give meaning to a sequence of events. the final section presents the results of a survey to test the chronological thinking of lower secondary school students carried out by the educational research institute.
