In the past, behaviorists were not likely to view cognition as a part of learning because cognition a. does not affect behavior b. disproved their theories c. is unobservable d. had never been studied

c. is unobservable      

Explanation:

According to the behaviorist, learning occurs mostly through observation. They believed a person learns various aspects of his or her life through ways of observation. the process of observation includes imitation, modeling, etc. Behaviorists demonstrated various studies that demonstrate behavior is a learned process such as experiments on classical conditioning. Whereas, cognition refers to the mental processes that involve comprehension and knowledge.

In the past, behaviorists were not likely to view cognition as a part of learning because cognition is unobservable.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals

what are the statements.?
