Death Thought Accessibility
Another paradigm that TMT researchers use to get at unconscious concerns about death is what is known as the death thought accessibility (DTA) hypothesis. Essentially, the DTA hypothesis states that if individuals are motivated to avoid cognitions about death, and they avoid these cognitions by espousing a worldview or by buffering their self-esteem, then when threatened, an individual should possess more death-related cognitions (e.g., thoughts about death, and death-related stimuli) than they would when not threatened.
The DTA hypothesis has its origins in work by Greenberg et al. (1994) as an extension of their earlier terror management hypotheses (i.e., the anxiety buffer hypothesis and the mortality salience hypothesis). The researchers reasoned that if, as indicated by Wegner’s research on thought suppression (1994; 1997), thoughts that are purposely suppressed from conscious awareness are often brought back with ease, then following a delay death-thought cognitions should be more available to consciousness then (a) those who keep the death-thoughts in their consciousness the whole time, and (b) those who suppress the death-thoughts but are not provided a delay. That is precisely what they found. However, it should be noted that other psychologists have failed to replicate these findings.
In these initial studies (i.e., Greenberg et al. (2004); Arndt et al. (1997)), and in numerous subsequent DTA studies, the main measure of DTA is a word fragment task, whereby participants can complete word fragments in distinctly death-related ways (e.g., coff_ _ as coffin, not coffee) or in non death-related ways (e.g., sk_ _l as skill, not skull). If death-thoughts are indeed more available to consciousness, then it stands to reason that the word fragments should be completed in a way that is semantically related to death.

Famous quotes containing the words death and/or thought:
“I was now at a university in New York, a professor of existential psychology with the not inconsiderable thesis that magic, dread, and the perception of death were the roots of motivation.”
—Norman Mailer (b. 1923)
“Men are born to write. The gardener saves every slip, and seed, and peach-stone: his vocation is to be a planter of plants. Not less does the writer attend his affair. Whatever he beholds or experiences, comes to him as a model, and sits for its picture. He counts it all nonsense that they say, that some things are undescribable. He believes that all that can be thought can be written, first or last; and he would report the Holy Ghost, or attempt it.”
—Ralph Waldo Emerson (1803–1882)
