In psychology, the behavioral perspective is a perspective which proposes that our behavior is learned as a result of our interaction with the environment. In other words, we learn from our environment how to act (based on reinforcement, punishment or by seeing other people's actions) and this learning is what determines our behavior.

In this example, Natassia believes that boys learn to be more aggressive because they are more frequently exposed to external pressures to fight. In other words, Natassia believes that aggression is a behavior that boys learn from their environment through the pressure of other people. Thus, this would exemplify the behavioral perspective.

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.
