«Continually changing scenes can keep a
child (or adult) riveted to a television screen for hours. Why are
fast-changing images in a video game or music video so intensely
pleasurable? In "Perceptual Pleasure and the Brain,"
Irving Biederman and Edward A. Vessel propose that the human brain
has evolved a craving for information that can be satisfied through
continual visual stimulation. Information from the eye speeds along
pathways in the brain that are rich in opioid receptors—the same
pleasure-modulating molecular receptors that are targeted by opiate
drugs—ultimately reaching so-called association areas, where
memories are elicited. A phenomenon called competitive learning can
explain why our craving for information sends us in search of visual
novelty and richly interpretable patterns. Using evidence from
brain-imaging studies, Biederman and Vessel suggest that boredom sets
in when people are presented inputs at a rate slower than their rate
of comprehension.»

E ficamos preocupados quando, questionando
os estudantes acerca da temática que os preocupa, como resposta não
obtemos referências relativamente à sua localidade, à sua
própria situação existencial, à sua direta interação, mas a
tudo o que vem pelos meios de comunicação de massa.
