“…Therefore, regarding landscapes and the space representation that they involve, it seems reasonable to infer that not only the physical features of a landscape affect its neural and psychological representation, but so do many other mechanisms, such as emotional processes (through, for example, the emotional/agreeable valence attributed to a landscape). Several previous studies have demonstrated the influence of emotional information on motor reactions [such as in posturography; 5,6,7,8].…”

From year-to-year, environment is becoming one of the major concerns of human societies. Few studies have investigated the biological processes involved in environmental scene perception. Here, we initiate a line of research by beginning to study emotional processes involved in this perception. Our results demonstrate a clear distinction between "Clean" and "Polluted" environments according to the pleasure and approach desire ratings they induced. Moreover, women expressed higher pleasure in the "Clean" condition, as did older participants. Finally, rural scenes induced higher pleasure in participants than urban ones.

“…In this framework, this study questions the interrelation between the motor and affective components of behavior [5]. We have explored this issue in the introductions of several of our studies [5,6,7,8], and it has been studied elsewhere. For example, Darwin proposed that emotion adapts behavior to the context [9].…”

“…Regarding the pattern of motor response to sexual content, we found a tendency to lean forward in “relapsers,” compared to “abstainers.” However, the link between sexual content and posturographic responses remains unclear (for a review, see Lelard et al, 2019). For example, passive viewing of sexually explicit films depicting heterosexual intercourse elicits a freeze‐like response rather than avoidance or estrangement (Mouras et al, 2015).…”

“…First, there is mounting evidence suggesting that emotional state can influence postural control. This has been explored through displacements of the center of pressure (COP) when the participant stood up on a posturographic platform (Gurfinkel, 1973; Lelard et al, 2019). Indeed, the evaluation of small body sways in response to emotional conditions demonstrated a consistent automatic responses pattern (Lelard et al, 2019).…”

Indeed, the evaluation of small body sways in response to emotional conditions demonstrated a consistent automatic responses pattern (Lelard et al, 2019). For instance, unpleasant visual stimuli (e.g., mutilation) or arousal stimuli (e.g., explicit sexual visual content) led to either backward movements (withdrawal behavior; Hillman et al, 2004) or freezing response, respectively (e.g., Azevedo et al, 2005; Mouras et al, 2015).…”

Background Spontaneous motor responses of approach and avoidance toward stimuli are important in characterizing psychopathological conditions, including alcohol use disorder (AUD). However, divergent results have been reported, possibly due to confounded parameters (e.g., using a symbolic vs. a sensorimotor task, implementation of approach–avoidance as a measure vs. a manipulation). Methods We studied whole‐body/posturometric changes by using a sensorimotor measure relying on embodied cognition principles to assess forward (approach) and backward (avoidance) spontaneous leaning movements. Over a 12‐second period, 51 male patients with AUD and 29 male control participants were instructed to stand still in response to both alcohol and sexual visual content. Patients with AUD were then divided into “abstainers” and “relapsers,” depending on their continuous abstinence at 2 weeks postdischarge (obtained via a telephone follow‐up interview). The effects of the group, the stimulus type, the experimental period, and their interactions on the posturometric changes were tested using mixed Analyses of variance (ANOVAs), with a significance threshold set at 0.05. Results Contrary to our expectations, patients and controls did not show significant difference in their forward/backward micromovements while passively viewing alcohol or sexual content (p > 0.1). However, in line with our hypothesis, patients who relapsed several weeks following discharge from the rehabilitation program were significantly more reactive and more likely to lean back during the first seconds of viewing alcohol cues (p = 0.002). Further, “relapsers” were more likely to lean forward during exposure to sexual content than participants who remained abstinent (p < 0.001). Conclusions Among individuals with AUD, there are distinct pattern of spontaneous movements that differentiate “abstainers” and “relapsers,” findings that can be understood in light of existing data and theories on action tendencies.
