The efficacy of different implicit death anxiety measures was examined. In Study 1 (N = 133), the death-word-fragment task (DWFT), commonly used to test death-thought accessibility in terror management theory (TMT) research, did not differentiate between mortality salience (MS) and control conditions. Instead, death-related word completions were associated with word dimensions other than MS induction. Study 2 (N = 155) tested three implicit measures (lexical-decision task, dot-probe task, ambiguous pictures task), which differentiated between conditions, revealing greater sensitivity than the DWFT. As TMT research widens its scope, investigating measures to capture implicit death concerns is important.
