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.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.        

is there multiple choice or do you need like an essay answer?
