Cognitive Biases in Pathological Health Anxiety

2016

Pathological health anxiety refers to the medically unfounded fear of suffering from a severe illness. Differences in cognitive processes related to attention, memory, and evaluation of health threat have been hypothesized to underlie pathological health anxiety. In no study, however, have researchers systematically and simultaneously assessed different cognitive biases. On the basis of the idea that multiple cognitive biases simultaneously contribute to psychopathology (the combined-cognitive-bias hypothesis), we compared 88 patients with pathological health anxiety, 52 patients with depressive disorder, and 52 healthy participants on their performance in several cognitive tasks involving…

Selective processing of food— and body—related information and autonomie arousal in patients with eating disorders

1998

Both attentional bias (using the modified Stroop Task) and autonomic reactivity (skin conductance level) to food- and body-related information were assessed in 25 patients with eating disorders (15 patients with anorexia, 10 patients with bulimia) amI 18 women controls. Patients with anorexia showed the greatest inrerference in color-naming foodrelated words. However, on this occasion there were no difierences in body condition, probably because of heterogeneity of clinical samples and because the control group were staff members, so the target information was very familiar to them. The groups differed in their autonomic reactivity while performing Ihe Stroop. Ihe patients with anorexia res…

Best not to bet on the horserace: A comment on Forrin and MacLeod (2017) and a relevant stimulus-response compatibility view of colour-word contingen…

2018

International audience; One powerfully robust method for the study of human contingency learning is the colour-word contingency learning paradigm. In this task, participants respond to the print colour of neutral words, each of which is presented most often in one colour. The contingencies between words and colours are learned, as indicated by faster and more accurate responses when words are presented in their expected colour relative to an unexpected colour. In a recent report, Forrin and MacLeod (2017b, Memory & Cognition) asked to what extent this performance (i.e., response time) measure of learning might depend on the relative speed of processing of the word and the colour. With keypr…

Is VIRTU4L larger than VIR7UAL? Automatic processing of number quantity and lexical representations in leet words.

2015

Recent research has shown that leet words (i.e., words in which some of the letters are replaced by visually similar digits; e.g., VIRTU4L) can be processed as their base words without much cost. However, it remains unclear whether the digits inserted in leet words are simply processed as letters or whether they are simultaneously processed as numbers (i.e., in terms of access to their quantity representation). To address this question, we conducted two experiments that examined the size congruity effect (i.e., when comparisons of the physical size of numbers are affected by their numerical magnitudes) in a physical-size judgment task. Participants were presented with pairs of leet words th…

Mental fatigue induced by prolonged self-regulation does not exacerbate central fatigue during subsequent whole-body endurance exercise

2015

International audience; It has been shown that the mental fatigue induced by prolonged self-regulation increases perception of effort and reduces performance during subsequent endurance exercise. However, the physiological mechanisms underlying these negative effects of mental fatigue are unclear. The primary aim of this study was to test the hypothesis that mental fatigue exacerbates central fatigue induced by whole-body endurance exercise. Twelve subjects performed 30 min of either an incongruent Stroop task to induce a condition of mental fatigue or a congruent Stroop task (control condition) in a random and counterbalanced order. Both cognitive tasks (CTs) were followed by a whole-body …
