(1994), Journal of Personality, 62, 615-640] is a self-report questionnaire measuring people's general tendency to suppress unwanted negative thoughts.

In their study, Kassin and Kiechel (1996) falsely accused students of causing a computer crash and found that 69% of them were willing to sign a false confession, 28% internalized guilt, and 9% confabulated details to support their false beliefs. The authors interpreted these results to mean that false confessions can be easily elicited. However, in their(More)

The present article describes two studies that addressed the issue of whether imagination inflation is related to certain personality characteristics (i.e. social desirability, imagery ability, and(More)

However, a critical analysis of the methods employed in these studies indicates that many of them do not address memory in the strict sense of the word. Instead, some of these studies assess the confidence that participants have in a fictitious (childhood)(More)
The present study investigated the relationship between deductive reasoning and phobic fear. In the first experiment, we succesfully evaluated a reasoning paradigm that was specifically designed to index interference effects of prior beliefs. Forty-two female undergraduates were presented with a series of syllogisms varying in believability and logical(More)

A large sample of adolescents (n = 437) completed the Defense Style Questionnaire for Adolescents, the Junior version of the Eysenck Personality Questionnaire, and a scale measuring symptoms of(More)
The current study examined the role of thought suppression in spider phobia. Spider phobic (n = 41) and non-phobic (n = 40) subjects were asked to monitor their thoughts for three 5 min periods. During the first period, all subjects were instructed to "think about anything". During the second period, half of the subjects received suppression instructions(More)
The present study examined developmental patterns in children's interpretation of anxiety-related physical symptoms and emotional reasoning (i.e., the tendency to infer danger on the basis of physical response information). A sample of 171 children aged between 4 and 13 years were interviewed after listening to a number of vignettes in which the presence(More)
