EXPRESS: A new experimental paradigm to investigate how imagery-based suggestions are embodied.

This study investigated how imagery-based-suggestions were embodied in perception and behaviour. In experiment 1, Participants listened to several suggestion scripts while stretching the left arm (they were required not to move). During 30s, the script invited participants to imagine the experimenter facing them.

The Simon effect under reversed visual feedback.

Our aim was to study the processes involved in the spatial coding of the body during actions producing multiple simultaneous effects. We specifically aimed to challenge the intentional-based account, which proposes that the effects used to code responses are those deemed relevant to the agent's goal. Accordingly, we used a Simon paradigm (widely recognized as a suitable method to investigate the spatial coding of responses) combined with a setup inducing a multimodal discrepancy between visual and tactile/proprioceptive effects (known to be crucial for body schema construction and action control).

Promoting a hand sanitizer by persuasive messages: moving bottle and background color as approach and avoidance cues.

In message-based health interventions, peripheral cues such as motion and color capture exogenous attention. These cues may elicit approach and avoidance motivation and the core ingredients of persuasion (argument framing, source of the message, and persuasion knowledge). In two studies, we presented participants with persuasive messages about a hand sanitizer.

On the relationship between valence and arousal in samples across the globe.

Affect is involved in many psychological phenomena, but a descriptive structure, long sought, has been elusive. Valence and arousal are fundamental, and a key question-the focus of the present study-is the relationship between them. Valence is sometimes thought to be independent of arousal, but, in some studies (representing too few societies in the world) arousal was found to vary with valence.

The visual size of graspable objects is needed to induce the potentiation of grasping behaviors even with verbal stimuli.

Merely perceiving objects usually grasped with a power or a precision grip (e.g., an apple vs.

Anticipating the magnitude of response outcomes can induce a potentiation effect for manipulable objects.

Merely seeing large objects (e.g., apples) potentiates power grip whereas seeing small objects (e.

How movement direction shapes the spatial representation of its effects: About the consequence of the ideomotor bidirectional association.

Ideomotor theories assume that action and perception share a common representational system in which a movement and its effect are equally represented and integrated by a bidirectional association. However, there is no mention of how this association leads to influence the representational content of each part. In this article, we investigated the influence of movement properties on the spatial representation of auditory effects.

When combined spatial polarities activated through spatio-temporal asynchrony lead to better mathematical reasoning for addition.

Several recent studies have supported the existence of a link between spatial processing and some aspects of mathematical reasoning, including mental arithmetic. Some of these studies suggested that people are more accurate when performing arithmetic operations for which the operands appeared in the lower-left and upper-right spaces than in the upper-left and lower-right spaces. However, this cross-over Horizontality × Verticality interaction effect on arithmetic accuracy was only apparent for multiplication, not for addition.

Effect of combined motor and spatial cues on mathematical reasoning: a polarity correspondence account.

We examined whether combined motor or spatial polarities could influence accuracy in two mathematical operations. Four experiments were conducted and showed that, when two corresponding polarities were activated, accuracy in multiplicative operations was greater than when non-corresponding polarities were activated, whereas no effect was found for additive operations. These results were established with motor cues (Left/Right and Arm Extension/Flexion, as behavioral approach-avoidance tendencies) and perceptual spatial cues (Left/Right and DOWN/UP cues).

Valence activates motor fluency simulation and biases perceptual judgment.

The concept of motor fluency, defined as the positive marking associated with the easy realisation of a movement, is used to explain the various compatibility effects observed between emotional valence and lateral space. In this work, we propose that these effects arise from the motor fluency simulation induced by emotionally positive stimuli. In a perceptual line bisection task (Landmark task) we primed each trial with an emotionally positive word, negative word, neutral word or no word before asking participants to verbally indicate the side of the vertical mark on the horizontal line (Experiment 1) or to indicate the longest side of the line (Experiment 2).

Reducing Stereotype Threat With Embodied Triggers: A Case of Sensorimotor-Mental Congruence.

In four experiments, we tested whether embodied triggers may reduce stereotype threat. We predicted that left-side sensorimotor inductions would increase cognitive performance under stereotype threat, because such inductions are linked to avoidance motivation among right-handers. This sensorimotor-mental congruence hypothesis rests on regulatory fit research showing that stereotype threat may be reduced by avoidance-oriented interventions, and motor congruence research showing positive effects when two parameters of a motor action activate the same motivational system (avoidance or approach).

Emotions and language about motion: Differentiating affective dominance with syntax from valence with semantics.

Motion as encoded in linguistic cues is used to differentiate affective valence and dominance. Participants were invited to rate their affective responses to different words along valence and dominance scales. The words were nouns describing static cues and verbs describing motion, connected to DOWN/UP and Avoidance/Approach cues.

A continuous mapping between space and valence with left- and right-handers.

In this research, we examined whether emotional valence could correspond to a continuous lateral bias in space, according to a mental metaphor that establishes the mapping between a concrete domain (space) and an abstract one (valence). Because acting with one's dominant hand is associated with fluency and positive valence (the bodily specificity hypothesis, or BSH), we asked strong right- and left-handers to perform two spatial location tasks using emotional faces with seven levels of valence. We hypothesized and showed through two studies that, according to the BSH, extreme valenced stimuli (as compared to moderate and weak ones) would be located more at the extremity of a horizontal line, according to the correspondences between handedness and the different valences of the stimuli.

Motor and cognitive integration: effect of bilateral behaviors on judgment.

Performing approach vs. avoidance behaviors (arm flexion vs. arm extension) on the one hand, and lateralized peripheral activations (left side vs.

Motor influences on judgment: Motor and cognitive integration.

Performing motor behaviours (arm flexion vs. extension) that correspond also to lateralized peripheral activations (left vs. right side) of the motivational systems of approach versus avoidance have been previously shown to impact cognitive performance and judgment.

Vertical metaphor with motion and judgment: a valenced congruency effect with fluency.

Following metaphorical theories of affect, several research studies have shown that the spatial cues along a vertical dimension are useful in qualifying emotional experience (HAPPINESS is UP, SADNESS is DOWN). Three experiments were conducted to examine the role of vertical motion in affective judgment. They showed that positive stimuli moving UPWARD were evaluated more positively than those moving DOWNWARD, whereas negative stimuli moving DOWNWARD were evaluated as less negative than those moving UPWARD.

Affective judgement about information relating to competence and warmth: an embodied perspective.

Several studies have shown that social judgement may be defined by two dimensions, competence and warmth. From a functional perspective, embodied theories have proposed that warmth may be associated with physical distance, whereas competence may be connected to a vertical motion (UPWARD/DOWNWARD). Two main studies were conducted to examine if approach-avoidance and vertical motion could influence affective judgements about traits representing these two social dimensions.

Influence of bilateral motor behaviors on flexible functioning: an embodied perspective.

To examine the influence of bilateral motor behaviors on flexibility performance, two studies were conducted. Previous research has shown that when performing unilateral motor behavior that activates the affective and motivational systems of approach versus avoidance (arm flexion vs. extension), it is the congruence between laterality and motor activation that determines flexibility-rigidity functioning (Cretenet & Dru, 2009).

Performing lateralized approach and avoidance behaviors: effects on perceptual, affective and confidence judgments.

In recent work, we showed that the judgment of affective stimuli is influenced by the degree of congruence between apparently innate hemispheric dispositions (left hemisphere positive and approach, right hemisphere negative and avoidance), and the type of movement produced by the contralateral arm (flexion-approach; extension-avoidance). Incongruent movements (e.g.

Influence of peripheral and motivational cues on rigid-flexible functioning: Perceptual, behavioral, and cognitive aspects.

Recent research has shown that performing approach versus avoidance behaviors (arm flexion vs. extension) effectively influences cognitive functioning. In another area, lateralized peripheral activations (left vs.

Influence of unilateral motor behaviors on the judgment of valenced stimuli.

Two experiments were conducted so as to examine how different motor activations (unilateral contraction and extension-flexion paradigms) of the motivational systems of approach and avoidance influenced participants' evaluations of valenced stimuli (figurative expressions and everyday life pictures). The results of the first Study (Study 1) showed that a motor congruence model was operative when processing positive facial expressions, this phenomenon was reversed, however, when negative faces were processed. This occurrence disappeared when weaker negative or positive faces were evaluated.

Players' quality of play and overall interest of the game in dyadic competition.

These experiments examined the cognitive processes involved in judging the quality of play of a player competing against another player and the overall interest of a competitive game as a function of the players' respective ability and motivation levels. For the quality of play of one player, a very simple information integration rule was found. Quality of play was judged almost exclusively as an additive function of the ability and motivation levels of the player.

A neurobehavioral investigation into judgmental processes: effect of bilateral motor behaviors.

Two experiments were conducted in order to examine how different bilateral motor activations of the approach and avoidance motivational systems influenced participants' evaluations of valenced stimuli (figurative expressions and pictures of everyday situations). The first Study (Study 1) showed that participants judged valenced expressions according to the motor congruence model put forward by Cretenet and Dru (2004). This may depend on the compatibility of the valenced stimuli with the congruency of the bilateral motor behaviors that involved two unilateral motor behaviors that are congruent to each other.

Influence of bilateral motor actions on judgements: additional evidence for the motor congruence hypothesis.

One experiment was conducted to examine the influence of bilateral motor actions involving two parameters of movement (flexion vs extension of the arm and laterality as bodily activation of different motivational systems) on judgements. Arm flexion or unilateral right contraction (involving the positive and approach motivational system) has been shown to determine positive evaluations, whereas arm extension or unilateral left contraction (involving the negative and withdrawal motivational system) has led to negative evaluations. Participants (N = 72) had to evaluate neutral Chinese ideographs after performing one of four combined bilateral motor actions (right flexion/left extension, bilateral flexion, bilateral extension, and left flexion/right extension).

Performance schemata in dyadic competition and cooperation.

We examined performance schemata in dyadic competitive and cooperative situations, that is, the ways people perceive the relationship between performance level, capacity level, and degree of motivation in situations in which two people confront or collaborate with one another. In Experiment 1, 104 participants judged the possible performance of Person A, whose ability and motivation levels were communicated, competing against Person B, whose ability and motivation levels were also communicated. When judging A's performance, participants seemed first to assess the difficulty of the task facing A and second to integrate information relative to A according to a rule with changing parameters already proposed by Surber (1981a, 1981b).
