Perception d’attributs des visages parlants par le nouveau-né humain

A visual preference method is used for studying how human newborns can process internal characteristics on speaking faces in a multimodal context. In a first experiment, two mobile faces associated with a speech sound are opposed: one is clear and the other is blurred. A preference for the clear face is observed. A second experiment contrasts two clear faces, showing lip movements respectively congruent and non-congruent with the associated speech sound. No preference is observed in this situation. These results show that newborns process mobile faces by orienting their attention on more information than that corresponding to very low spatial frequencies. It seems however that they cannot detect the correspondences between the lip movements and the associated sounds.     

La distribution du voisinage influence l'amorçage orthographique non masqué des mots écrits

The aim of the present research is to study whether orthographic neighbourhood distribution influences unmasked orthographic priming. Two word conditions were compared in the lexical decision task. All word targets had two higher frequency neighbours that were either spread across two letter positions (SINGE/linge-songe) or concentrated on a single letter position (RUCHE/riche-roche). Results showed an inhibitory effect of unmasked orthographic priming. Furthermore, this priming effect was influenced by the target neighbourhood distribution. Priming was only found when the word targets had two neighbours that were spread across two letter positions. These data are discussed within an interactive activation framework in terms of prime activation (Versace and Nevers, 2003).     

L'effet de l'hétérogénéité sémantique dans la détection de mots

The effects of three semantic factors (semantic priming of the target, semantic distance between the word-target and distractors, and semantic heterogeneity of the target context) on the detection of a word among other words were examined by using the classical paradigm of target detection (varying the number of distractors). Results showed that these three semantic factors affect performance: a target was better detected 1) when primed by its superordinate category than when it was defined as the “odd-one-out”; 2) when the semantic context was homogeneous than heterogeneous; and 3) when it was semantically unrelated to the context than semantically related. These results help specifying the cognitive processing of each word while searching for a word among others.     

Imagerie visuelle et rappel moteur d'enchaînements : effet du bilinguisme français vs créole

The two experiments reported in the present paper concern (i) the differential imagery value of French and Creole and (ii) the influence of language on the recall of sequences of patterned movements in a bilingual population. Creole words were obtained a higher imagery value than French words, certainly because Creole is an oral and vernacular language. Motor recall scores were better when the sequence was presented in Creole compared to French. The generation of visual images by Creole would facilitate the memorization and recall of new sequences of movements. The effect of language on imagery value of words and motor recall among bilingual French-Creole subjects was discussed in terms of nature of information encoding in each language.     

Visual exploration of reaching space during left and right arm movements in 6-month-old infants

Infant's manual laterality and eye-hand coordination emerge during the second part of the first year of life with the development of reaching. Nevertheless, little is known about the potential asymmetric characteristics of this coordination. The aim of this study was to describe visuo-spatial exploration in 6-month-old infants during reaching, according to the hand used. More specifically, we examined if the use of the left or the right hand was linked to a specific type of visual exploration. Gaze direction during goal-directed reaching towards an object placed on the table was measured with a remote ASL 504 eye tracker (Bedford MA). Twelve babies aged 6 months were observed during six reaching sessions, alterning three sessions with an object on the left side of the subject and three with an object on the right side. Gaze direction and some hand variables (hand activity, hand opening and hand position from the body) were coded with The Observer software. Results showed that babies visually explore their reaching space differently according to the hand used: they look more at the object when they use their right hand and more around the object when they use their left hand; they also look more often at their left hand than at their right one. These results suggest that an asymmetric visuo-manual coordination exists as early as 6 months: vision seems to support (1) left hand during reaching for evaluate distances from object to baby by means of visual feedbacks and (2) right hand for identify what sort of object is. Results are discussed in light of manual specialization and specific hemispheric skills at this age.     

Influence de la préparation d’une atteinte manuelle sur l’orientation initiale de l’attention lors d’une tâche de recherche visuelle

This paper deals with the links between spatial attention and reaching movement's motor preparation. During a visual search task, participants prepare to manually reach a button of the numeric keypad and execute it when they find an intruder on the screen. The experimental devices allowed us to control two directions: on the one hand, the direction of the response button's manual reach (on the horizontal plane) and on the other hand, the direction of the intruder's direct attentional reach, starting from the fixation point (on the vertical plane). The results show that: (a) reaction times are shorter when there is a directional congruence between these two directions than when there is incongruence; (b) this effect is significant when attention is voluntarily shifted, whereas it is no longer significant when attention is automatically captured by an intruder. These results suggest that visual search's initial direction is determined by the prepared manual reach. These data are discussed in the premotor theory of attention's framework.     

Le TASC200, une épreuve d’attention et de saillance visuelle : fidélité, validité et normes préliminaires

In the clinical setting, attention is classically assessed by tasks that do not take into account theoretically important aspects, such as the salience-based guidance of visual search. The aim of this study was to develop a paced paper-and-pencil task for clinical use based on strong theoretical accounts that would assess salience-based visual search and that would meet the psychometric requirements for the assessment of attention. Participants were required to search and cancel targets of varying visual saliences as quickly and as accurately as possible during a predefined short period of time. The targets were intermixed with distractors. In agreement with theories of salience-based visual search, the results showed that the most salient targets were detected more easily than less salient targets. The task exhibited a quite acceptable test-retest reliability, and two construct validity studies showed that different scores involve different processes. This new task fully complies with the major theories of salience-based guidance of attention during visual search. It also meets the requirements of a plausible clinical task since its psychometric qualities are quite good. Preliminary normative data (n = 863) are presented for clinical use.     

Validation of the French version of the Object Spatial Imagery and Verbal Questionnaire

IntroductionThe Object Spatial Imagery and Verbal Questionnaire (OSIVQ) measures individual differences in Visual-Verbal cognitive style and distinguishes between spatial and object visual imagery.ObjectiveThe aim of this study was to evaluate the psychometric properties of a French version of the OSIVQ.MethodSeven hundred fifty-two participants completed the French OSIVQ and 144 of them also completed a paper-and-pencil assessment to evaluate spatial imagery, object imagery and verbal abilities.ResultsPrincipal component analyses of the OSIVQ showed good internal construct validity. Results also revealed pronounced individual differences and a significant gender effect. Confirmatory factorial analyses gave support to a three-dimensional model of cognitive style. Furthermore, correlations were observed across the different dimensions of the questionnaire and specific paper-and-pencil tasks.ConclusionOur results highlight the good psychometric properties of the French version of the OSIVQ.     

Fidélité inter juge d’une mesure du stress par échelle visuelle analogique

The use of a visual analogue scale (VAS) for the assessment of stress during occupational health examination could be an useful tool. However, psychometrics features of the VAS have to be assessed. The aim of this study is to test the inter judge reliability of the VAS in a psychological dimension assessment. Two occupational physician have used the VAS in a worker group. There is no significant difference in the distribution of VAS values. This result supports the hypothesis of a satisfactory inter judge reliability of the VAS in stress measurement.     

A review of processing and analysing visual metaphors in psychology

IntroductionA visual metaphor is an image depicting an incongruity in the spatial distribution of visual elements, which is not consistent with reality. In this paper, we present an overview of theoretical and empirical studies on visual metaphor processing.ObjectiveFirstly, attention is given to the spatial distribution of visual elements, which defines the type of visual metaphors as well as the meaning operations required to understand the communicative message. The paper then reviews several empirical studies that collect behavioural measures for assessing visual metaphor processing using questionnaires and exploring the role played by cognitive abilities. In line with the contemporary literature, we then present three semiotic dimensions for visual metaphor processing, namely the expression, conceptualisation, and communication. We then present a pilot study that focusses on these three dimensions. Few research studies have collected behavioural data for visual metaphors processing. This may be due to the lack of theoretical framework in the corresponding field of research. These three semiotic dimensions highlight the value of pursuing research on visual metaphors in the scope of psychology. The presented pilot study could be a starting point for the investigation of visual metaphors in the framework of psychology.ConclusionWe propose future avenues of research that consider the visual structure of metaphors and meaning operations while assessing the influence of cognitive abilities in visual metaphor processing.
