A phenomenon whereby the uninterrupted repetition of a word eventually leads to a sense that the word has lost its meaning.
The concept of semantic satiation was described by E. Severance and M.F. Washburn in The American Journal of Psychology in 1907. The term was introduced by psychologists Leon James and Wallace E. Lambert in the article "Semantic Satiation Among Bilinguals" in the Journal of Experimental Psychology (1961).
Several prominent moral psychologists and philosophers make much of a phenomenon they term moral dumbfounding, which is characterized by dogmatic insistence on a moral judgment for which no good reasons can be given. They hold that the phenomenon shows something important about ordinary moral judgment: that commonplace reasons offered for moral judgment are mere post hoc rationalizations of decisions made on other grounds. The chapter argues that the prominent and influential dumbfounding study does not work on its own terms, because its examples ignore crucial distinctions concerning harm and wrongness, and between dumbfounding and inarticulate reason-responsiveness. In fact there are good reasons for moral condemnation of every case they consider, but the problem is not just a matter of poorly chosen examples.
In a 2006 book by Daniel Levitin entitled This Is Your Brain on Music: The Science of a Human Obsession, he states that research has shown musicians and people with obsessive–compulsive disorder (OCD) are more likely to suffer from earworm attacks. An attack usually involves a small portion of a song, a hook, equal to or less than the capacity of one's auditory short-term memory. Levitin reports that capacity as usually 15 to 30 seconds.
Our findings offer a neural basis for the
spontaneous and sometimes vexing experi-
ence of hearing a familiar melody in one’s
head. Whereas previous investigations have
explicitly directed subjects to imagine a
specific auditory experience 2–4,we provided
no instruction. Instead, simply muting
short gaps of familiar music was sufficient to
trigger auditory imagery — a finding that
indicates the obligatory nature of this phe-
nomenon. Corroborating this observation,
all subjects reported subjectively hearing
a continuation of the familiar songs, but not
of the unfamiliar songs, during the gaps in
Failures of self-regulation are common, leading to many of the most vexing problems facing contemporary society, from overeating and
obesity to impulsive sexual behavior and STDs. One reason that people may be prone to engaging in unwanted behaviors is heightened
sensitivity to cues related to those behaviors; people may overeat because of hyperresponsiveness to food cues, addicts may relapse
following exposure to their drug of choice, and some people might engage in impulsive sexual activity because they are easily aroused by
erotic stimuli. An open question is the extent to which individual differences in neural cue reactivity relate to actual behavioral outcomes.
Here we show that individual differences in human reward-related brain activity in the nucleus accumbens to food and sexual images
predict subsequent weight gain and sexual activity 6 months later. These findings suggest that heightened reward responsivity in the
brain to food and sexual cues is associated with indulgence in overeating and sexual activity, respectively, and provide evidence for a
common neural mechanism associated with appetitive behaviors
Osborn's research found that the more an individual believed in television portrayals of romance, the less likely they were to be committed to their relationships. In August 2012, several of the most-watched television shows (Burn Notice, True Blood, The Big Bang Theory, and Two and a Half Men) featured romantic relationships prominently throughout their episodes. This research is especially important at helping individuals understand the impact that television viewing can have on their relationships.
“In this study I found that people who believe the unrealistic portrayals on TV are actually less committed to their spouses and think their alternatives to their spouse are relatively attractive,” Osborn said. “My hope would be that people would read this article and take a look at their own relationships and the relationships of those around them. How realistic are your expectations for your partner and where did those expectations come from?”
"There are several reasons why media usage may be associated with self-objectification among women. First, greater usage of sexually objectifying media may be associated with higher levels of self-objectification because these media focus on women's physical appearance (Aubrey & Frisby, 2011; Baker, 2005) and place pressure on women to focus on their own appearance (Fredrickson & Roberts, 1997).
