La version française du dictionnaire pour le LIWC : modalités de construction et exemples d’utilisation

LIWC is, originally, a text analysis program that counts words of English texts in psychologically meaningful categories. It provides an analysis (in percentage) for 80 dimensions of language (functional words, topics, punctuation). The goal of this methodological note is to present the French LIWC. This version respects the structure of the categories of the English version of the software and gives explanations about the user guide such the preparation of the to be analyzed texts. Then, we explain the decisions for translating the English dictionary into French. We emphasize the constraints imposed by the morphology of written French language and the difficulties encountered (elision of the article, elision of negation and of verbs’ tense). Presenting the translation problems allows understanding the modalities of construction of the dictionary and allows for a LIWC user to build a personalized dictionary in order to analyze contents more suited to the research needs. A qualitative comparison of dimensions obtained with both the French and English versions for 66 bilingual texts of various types and contents provides satisfactory results. A statistical comparison of 119 expressive writings produced by students from three university courses (Humanities, Sciences and Psychology) about a given event (success or failure to an exam) shows the validity of the French version for identifying the expressed contents. Thus, this tool should be efficient for undertaking research in different fields of psychology (health, work and education) concerning oral and written language produced in different contexts.     

Specific and differential prediction of health anxiety by disgust sensitivity and propensity

Current models of health anxiety suggest that fear resulting from false alarms to perceived threats to one's health results in the development of hypochondriasis and related disorders. Disgust has been proposed as an affective response that may function as an etiological and maintenance mechanism in health anxiety. Moreover, the way in which an individual perceives the disgust response (disgust sensitivity) may affect health anxiety, separately from their likelihood of experiencing disgust (disgust propensity). The present study utilized multiple hierarchical regression analysis to investigate the degree to which self-reported disgust sensitivity and disgust propensity differentially predict elevated health anxiety in a sample of 620 non-treatment-seeking undergraduates. Further, this effect is tested in comparison to that of anxiety sensitivity, a construct demonstrated to be strongly related to health anxiety. Analyses indicate that disgust sensitivity, rather than disgust propensity, is primarily responsible for this relation. An additional analysis tested the specificity of disgust sensitivity relative to anxiety sensitivity. Disgust sensitivity was no longer significant after including anxiety sensitivity in the model. Suggestions for further evaluation of this relation are provided. These results suggest that although disgust sensitivity may appear related to health anxiety, this relation may be confounded by anxiety sensitivity.     

On some recent moves in defence of doxastic compatibilism

According to the doxastic compatibilist, compatibilist criteria with respect to the freedom of action rule-in our having free beliefs. In Booth (Philosophical Papers 38:1–12, 2009), I challenged the doxastic compatibilist to either come up with an account of how doxastic attitudes can be intentional in the face of it very much seeming to many of us that they cannot. Or else, in rejecting that doxastic attitudes need to be voluntary in order to be free, to come up with a principled account of how her criteria of doxastic freedom are criteria of freedom. In two recent papers, Steup (Synthese 188:145–163, 2012; Dialectica 65(4):559–576, 2011) takes up the first disjunct of the challenge by proposing that even though beliefs cannot be practically intentional, they can be epistemically intentional. McHugh (McHugh forthcoming) instead takes up the second disjunct by proposing that the freedom of belief be modelled not on the freedom of action but on the freedom of intention. I argue that both Steup’s and McHugh’s strategies are problematic.     

The Positive Influence of Creating a Holistic Facial Composite on Video Line‐up Identification

Witnesses to a crime may be asked to create a facial composite of the offender from memory. They may then view a suspect in a police line‐up. Previous research on this topic has found both recognition impairment and enhancement following composite construction. In Experiment 1, creator‐participants employed the holistic facial composite system system EFIT‐V or the feature‐based E‐FIT system to create a single composite, and in Experiment 2, creators constructed up to three EFIT‐Vs. In both experiments, facial composite creators were one‐and‐a‐half times more likely than non‐composite creating controls to make correct target identifications from a video line‐up. No between condition effects were found in target‐absent trials in Experiment 1. The development of holistic facial composite systems has enhanced suspect identification rates in police investigations, and these results suggest that the use of such a system can also have a positive influence on a composite‐creating witness' later recognition of the suspect.

Parental socioeconomic status and the neural basis of arithmetic: differential relations to verbal and visuo‐spatial representations

We examined the relation of parental socioeconomic status (SES) to the neural bases of subtraction in school‐age children (9‐ to 12‐year‐olds). We independently localized brain regions subserving verbal versus visuo‐spatial representations to determine whether the parental SES‐related differences in children's reliance on these neural representations vary as a function of math skill. At higher SES levels, higher skill was associated with greater recruitment of the left temporal cortex, identified by the verbal localizer. At lower SES levels, higher skill was associated with greater recruitment of right parietal cortex, identified by the visuo‐spatial localizer. This suggests that depending on parental SES, children engage different neural systems to solve subtraction problems. Furthermore, SES was related to the activation in the left temporal and frontal cortex during the independent verbal localizer task, but it was not related to activation during the independent visuo‐spatial localizer task. Differences in activation during the verbal localizer task in turn were related to differences in activation during the subtraction task in right parietal cortex. The relation was stronger at lower SES levels. This result suggests that SES‐related differences in the visuo‐spatial regions during subtraction might be based in SES‐related verbal differences.     

Differential prefrontal-temporal neural correlates of semantic processing in children

This study used functional magnetic resonance imaging (fMRI) to examine brain-behavior correlations in a group of 16 children (9- to 12-year-olds). Activation was measured during a semantic judgment task presented in either the visual or auditory modality that required the individual to determine whether a final word was related in meaning to one of two previous words (e.g., found-tank-lost). The main finding was that higher performers (i.e., accuracy) were associated with more activation in posterior representational systems including the inferior and middle temporal gyri, whereas lower performers were associated with more activation in anterior regions including the inferior and middle frontal gyri. This pattern of results was interpreted as reflecting an elaborated semantic representational system in temporal areas for the high accuracy performers that allowed them to efficiently and accurately make meaning based judgments. The low accuracy performers may have an inaccurate or weakly interconnected semantic system that results in greater use of frontal areas in a feature selection process.
