Cardiac threat appraisal and depression after first myocardial infarction
2012
The present study investigated cardiac threat appraisal and its association with depression after first myocardial infarction (MI). A semi-structured interview allowing for DSM-IV-Axis I diagnoses was administered to 36 patients after first MI. Patients completed self-reports 5 to 15 days after the MI (time 1), 6 to 8 weeks later (time 2) and again 6 months later (time 3). Assessments at time 1 included indices of cardiac threat appraisal, locus of control, coping, and depression while at time 2 and time 3 only measures of depression were obtained. Cardiac threat appraisal was significantly correlated with depression at time 1, but was unrelated to depression scores at time 2 and time 3. Fu…
Understand and optimize mental strategies during motor learning
2022
Motor imagery-based motor learning, also known as mental practice, can improve motor performance. However, questions remain concerning the mechanisms involved in mental practice, at the neurophysiological and behavioral levels. In a first study, we show an increase of short-interval intracortical inhibition during motor imagery, supporting the hypothesis that motor imagery induces the generation of an inhibited motor command. In a second study, we show modulations in functional connectivity between the cerebellum and the primary motor cortex following a mental practice session, corroborating at the neurophysiological level the hypothesis of the involvement and updating of internal models af…
Orthographic and Phonological Neighborhoods in Naming: Not All Neighbors Are Equally Influential in Orthographic Space
1997
Abstract The neighborhood size effect refers to the finding that single word naming is faster for stimuli that are orthographically similar to numerous lexical entries. We explored the nature of this phenomenon in five experiments with French pseudowords and words, and we examined the orthographic and the phonological characteristics of neighbors through quantitative analyses of a word corpus. Experiments 1 and 2 showed that the facilitatory effect of neighborhood size was determined by a subset of neighbors, called phonographic neighbors, which are also phonologically similar to the target letter string. Experiments 3 to 5 aimed at assessing the influence of phonographic neighbors as a fun…
Is perception a two-way street ?The case of feedback consistency in visual word recognition
1998
It is generally assumed that during reading, the activation produced over orthographic units feeds forward to phonological units. Supporting interactive models of word recognition, Stone, Vanhoy, and Van Orden (1997) recently claimed that phonological activation reverberates to orthographic processing units and consequently constrains orthographic encoding. They found that the consistency of the relations between phonology and orthography (feedback consistency) influenced lexical decision performance. We explored the effect in five experiments conducted with French words. Although feedback consistency affected writing performance, no significant effect was observed in lexical decision even …
