The expression to be a bore had been used in print in the sense of "to be tiresome or dull" since 1768 at the latest. The expression "boredom" means "state of being bored," 1852, from bore (v.1) + -dom. It also has been employed in a sense "bores as a class" (1883) and "practice of being a bore" (1864, a sense properly belonging to boreism, 1833). The word "bore" as a noun meaning a "thing which causes ennui or annoyance" is attested to since 1778; "of persons by 1812". The noun "bore" comes from the verb "bore", which had the meaning "[to] be tiresome or dull" first attested [in] 1768, a vogue word c. 1780–81 according to Grose (1785); possibly a figurative extension of "to move forward slowly and persistently, as a [hole-] boring tool does."
A 1989 study indicated that an individual's impression of boredom may be influenced by the individual's degree of attention, as a higher acoustic level of distraction from the environment correlated with higher reportings of boredom. Boredom has been studied as being related to drug abuse among teens. Boredom has been proposed as a cause of pathological gambling behavior. A study found results consistent with the hypothesis that pathological gamblers seek stimulation to avoid states of boredom and depression. It has been suggested that boredom has an evolutionary basis that encourages humans to seek out new challenges. It may influence human learning and ingenuity.
There was also a piano, well littered with music, a sewing bag thrown down upon a cretonned window seat, and the generous fireplace was flanked by two huge baskets, one heaped with magazines, the other a perfectly round mound of yellow fur, which suddenly took form and life as a yellow tabby cat fastened hopeful topaz eyes upon them, blinked away a brief disappointment, and then yawned with ennui.
