Research on memory construction shows that
- hypnotic suggestion is a particularly effective technique for accurate memory retrieval
- recent events are more vulnerable to memory distortion than events from our more distant past
- false memories often feel as real as true memories
- it is very difficult to lead people to construct memories of events that never happened

- false memories often feel as real as true memories

Explanation:

            Memories are very important to everyone.It is the basis of our lives. We live by our memory thinking about our past good times and sometimes bad times.

           Memories forms and are eliminated every single moment. Memory construction is the formulation or formation of a new memories. And the process of constructing old memories are called memory reconstruction.

          Many research have been done on memories by researchers. And one of the most important fact of the research done on memory construction shows that the false memories that are built in the brain often feel as real as true memories.

Thus the answer is --

"false memories often feel as real as true memories"

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
