Instead, the theory espouses a bidirectional influence in which evolutionary pressures alter human development such that individuals are able to create increasingly complex environmental innovations that, "in turn, create new selection pressures for the evolution of specialized biological systems for functional consciousness, thought, language, and symbolic communication" (p.
Some of Penny's comedic role in the series is rooted in her ability to execute practical and simple solutions to problems of which the guys try to solve through complicated or scientific means. For example, in the episode "", Sheldon reveals that in spite of his ability to talk excessively to people in small groups, he has a severe case of stage fright, and wouldn't be able to accept an award. While Leonard tries to get to the root of his problem through a psych evaluation, and attempts to use meditation, Penny solves the problem by having him buy a new suit and getting him intoxicated right before he makes his speech.
In "", Penny stops by when Leonard and Howard are working late on their guidance system prototype and she stays helping them make parts for it. She is very happy getting to play scientist. She and Bernadette are both furious when Raj tells them that they went to go see a movie and lied to them, but all is forgiven when they return with flowers, an apology, and the offer to pay for dinner.
"Actually, that's not true, Leonard. Recently I've been thinking that given the parameters of your experiment, the transport of electrons through the aperture of the Nano fabric metal rings is qualitatively no different from the experiment already conducted in the Netherlands...observed phase shift in the diffusing electrons inside the metal ring already conclusively demonstrated the electron analog of the Aharonov-Bohm quantitative interference effect...That's it, that's all I know. Oh, wait! Fig Newton's were named after a small town in Massachusetts not the scientist!"[Penny unknowingly insulting Leonard's work]
Bandura's social cognitive theory stands in clear contrast to theories of human functioning that overemphasize the role that environmental factors play in the development of human behavior and learning.
