“…This effect supports the finding that the amount of time used to determine the laterality of a hand figure is reliably influenced by the actual posture of the responding body part during the task (Jeannerod, 1994; Jeanerod & Decety, 1995; Lameira et al, 2008a; Lameira et al, 2009; Mercier, Aballea, Vargas, Paillard, & Sirigu, 2005; Parsons, 1987, 1994; Parsons & Fox, 1998; Sirigu & Duhamel, 2001; Vargas, Oliver, Craighero, Fadiga, Duhamel, & Sirigu, 2004). This effect also supports our previous findings that the response to a dorsal view of a hand figure is faster than the response to a palm view in a laterality judgment made with a prone posture of the participant's hand (Lameira et al, 2008a,b, 2009).…”

“…The present results also revealed an effect of view on MRTs in both groups although opposite patterns were found. In the Hand group in which the participants considered the stimulus to be their own hands, the dorsal view of their hand yielded faster responses than the palm view (Lameira, Guimarães-Silva, Ferreira, Werneck-Galvão, Pereira Jr, & Gawryszewski, 2008b; Lameira et al, 2009; Parsons, 1994; Rangel et al, 2010). This effect supports the finding that the amount of time used to determine the laterality of a hand figure is reliably influenced by the actual posture of the responding body part during the task (Jeannerod, 1994; Jeanerod & Decety, 1995; Lameira et al, 2008a; Lameira et al, 2009; Mercier, Aballea, Vargas, Paillard, & Sirigu, 2005; Parsons, 1987, 1994; Parsons & Fox, 1998; Sirigu & Duhamel, 2001; Vargas, Oliver, Craighero, Fadiga, Duhamel, & Sirigu, 2004).…”

A visual stimulus (e.g., a letter, word, or object) may have a lasting effect on the processing of subsequent stimuli. The present study verified the priming effect of a figure (i.e., five-petal daisy) on manual reaction time (MRT) to another equal or different five-petal daisy. Two distinct groups were tested. One group was instructed that the five-petal daisy represented a human hand. The other group was instructed that the five-petal daisy represented a flower. The figures in the pairs of stimuli could share or not share some features such as handedness and view. In both groups, after being informed whether the five-petal daisy represented a flower or human hand, an uninformative flower was presented for 200 ms in the center of the screen. After 1000 ms, a second flower was presented in the same location until the observer responded by pressing a left or right switch. The results showed that prior presentation of the five-petal daisy affected MRT only when the figure represented a human hand. Furthermore, an opposite effect of view on MRT was found. The shorter MRT to the back (dorsal) view of the figure that represented a human hand could be attributable to a faster response to the dorsal view of a hand figure made with a prone posture of the participants' hand than to a front (palm) view. The longer MRT to the back view of the figure that represented a flower may be due to a mental rotation of the object along its vertical axis before selecting the correct response because the response was based on the position of the asymmetrical petal in the canonical front view of the daisy.

“…The handedness recognition paradigm is known to depend on implicit motor simulation (Jeannerod, 2001) and has been used mostly with visual stimuli (Parsons, 1994;Gawryszewski et al, 2007;Lameira et al, 2008a;Lameira et al, 2008b). The present work is the first to investigate the haptic properties of motor simulation in a handedness recognition task.…”

“…This is because biomechanical constraints that normally restrict the actual movement of body parts also influence their implicit movement (Parsons, 1987(Parsons, , 1994Petit, Pegna, Mayer, & Hauert, 2003). Movements that are difficult to execute, for example, are also difficult to be mentally simulated and lead to longer reaction times (Gawryszewski, Silva-dos-Santos, Santos-Silva, Lameira, & Pereira, 2007;Lameira, Guimarães Silva, Werneck-Galvão, Pereira, & Gawryszewski, 2008a;Parsons, 1987Parsons, , 1994.…”

The handedness recognition of visually perceived body parts engages motor representations that are constrained by the same biomechanical factors that limit the execution of real movements. In the present study, we used small plastic cutouts that represented the human hand to investigate the properties of mental images generated during their haptic exploration. Our working hypothesis was that any handedness recognition task that involves body parts depends on motor imagery. Forty-four blindfolded, right-handed volunteers participated in a handedness evaluation experiment using their index finger to explore either the back or palm view of a haptic stimulus that represented the human hand. The stimuli were presented in four different orientations, and we measured the subjects' response times. Our results showed that stimulus configurations that resemble awkward positions of the human hand are associated with longer response times (p < .006), indicating that the haptic exploration of stimuli that represent body parts also leads to motor imagery that is constrained by biomechanical factors.

“…If coding the spatial features of the body part is framed within a mental body structure (i.e., the BSR), then coding should be modulated as a function of (a) the anatomo‐physiological constraints of the human body; (b) the least awkward way of moving the limbs, and (c) the frontal/back plane. However, if the BS also influences automatic and implicit body part coding, as in the explicit body part processing (e.g., in handedness recognition and hand laterality judgment; de Lange et al, 2008; Funk & Brugger, 2007; Lameira et al, 2008; Parsons, 1994; Petit & Harris, 2005, or in‐between test, Dolgilevica et al, 2020; Tamè et al, 2017), then the proprioceptive features of one's own corresponding body part should favour view‐related priming effects, and observers should code handedness by cognitively binding the stimulus's visual features to the proprioceptive features of their own corresponding body part, elaborated through the BS (Ionta & Blanke, 2009; Schwoebel et al, 2001).…”

Does the body talk to the body? The relationship between different body representations while observing others’ body parts

The way human bodies are represented is central in everyday activities. The cognitive system must combine internal, visceral, and somatosensory, signals to external, visually driven information generated from the spatial placement of others’ bodies and the own body in the space. However, how different body representations covertly interact among them when observing human body parts is still unclear. Therefore, we investigated the implicit processing of body parts by manipulating either the body part stimuli’ posture (conditions a and b) or the participants’ response body posture (conditions c, d, and e) in healthy participants (N = 70) using a spatial compatibility task called Sidedness task. The task requires participants to judge the colour of a circle superimposed on a task‐irrelevant body part picture. Responses are facilitated when the spatial side of the responding hand corresponds to the spatial code generated by the hand stimulus's position with respect to a body of reference. Results showed that the observation of the task‐irrelevant body parts oriented participants’ attention and facilitated responses that were spatial compatible with the spatial position such body parts have within a configural representation of the body structure (i.e., Body Structural Representation) in all the five experimental conditions. Notably, the body part stimuli were mentally attached to the body according to the most comfortable and less awkward postures, following the anatomo‐physiological constraints. Moreover, the pattern of the results was not influenced by manipulating the participants’ response postures, suggesting that the automatic and implicit coding of the body part stimuli does not rely on proprioceptive information about one's body (i.e., Body Schema). We propose that the human body's morphometry knowledge is enriched by biomechanical and anatomo‐physiological information about the real body movement possibilities. Moreover, we discuss the importance of the automatic orienting of attention based on the sidedness within the context of imitational learning.
