“…Walking direction can be detected quickly from seeing biological movements (Bertenthal & Pinto, 1994;Chang & Troje, 2008;2009a;2009b;Kuhlmeier, Troje & Lee, 2010;Neri, Morrone & Burr, 1998; see also Wang, Yang, Shi & Jiang, 2014), it can trigger attention (Shi, Weng, He & Jiang, 2010), and influence responses, even when it is task-irrelevant (Bosbach et al, 2004(Bosbach et al, , 2005Kourtzi & Shiffrar, 1999;Thornton & Vuong, 2004;Verfaillie, 2000).…”

Response priming in general is a suitable tool in cognitive psychology to investigate motor preactivations. Typically, compatibility effects reflect faster reactions in cases in which prime and target suggest the same response (i.e., compatible trials) compared with cases in which prime and target suggest opposite responses (i.e., incompatible trials). With moving dots that were horizontally aligned, Bermeitinger (2013) found a stable pattern of results: with short SOAs, faster responses in compatible trials were found; with longer SOAs up to 250 ms, faster responses in incompatible trials were found. It is unclear whether these results are specific to the special motion used therein or whether it generalizes to other motions. We therefore used other motions realized by arrangements of dots. In four experiments, we tested point-light displays (biological coherent walkers vs. less biological scrambled/split displays) as primes. In two experiments, eye gaze motions realized by moving dots representing irises and pupils (i.e., biological) versus the same motion either without surrounding face information or integrated in an abstract line drawing (i.e., less biological) were used. We found overall large positive compatibility effects with biological motion primes and also positive-but smaller-compatibility effects with less biological motion primes. Most important, also with very long SOAs (up to 1320 ms), we did not find evidence for negative compatibility effects. Thus, the pattern of positive-followed-by-negative-compatibility effects found in Bermeitinger (2013) seems to be specific to the materials used therein, whereas response priming in general seems an applicable tool to study motion perception.

“…Thornton and Vuong (2004) used point-light walkers in a flanker paradigm. Participants were asked to judge the direction of a central target (pointlight walker) that was flanked by a number of additional walkers, walking in the same (congruent trials) or different (incongruent trials) direction.…”

“…Walkers always appeared at the same location in the center of the screen and we suggest that it is unlikely that large eye movements significantly affected results in the current research. Furthermore, eye movements are not generally thought to play a major role in biological motion processing and PLWs can be processed accurately in the periphery [57,58]. A final limitation of the current study could be the range of walking speeds used.…”

IntroductionAction and perception are two inherently linked aspects of human behavior that allow us to understand and interact with our surroundings. The interplay between action production and perception enables humans to act in a number of highly demanding situation such as unusual, novel or unstable environments [1]. Babies interact with their environment in a myriad of different ways such as imitation, selfmotion and observing the examples of others [2][3][4]. These interactions serve to shape not only their knowledge about the world, but also their understanding of the functionality of their bodies.Action performance interacts with action perception, and viceversa. This is reflected in the brain, as both performing and perceiving actions activate similar cortical areas [5]. Previous research has revealed significant interactions between action perception and action execution, and studies have shown that action perception can interfere with action execution reciprocally [6][7][8]. It is particularly insightful to study such interactions in populations with abnormal skeleto-muscular and/or neural development, as in these populations the brain may have adapted differently to handle physical differences, which in turn may influence how affected individuals interact with their surroundings. For example Sinha et al. [9] have shown that individuals with autism spectrum disorder, adapt their sensory input atypically, resulting in diverse behavioral traits. Down Syndrome (DS) is one of the most common genetic disorders (14 per 10 000 live births) caused by the presence of a complete or partial third copy of chromosome 21 (Trisomy 21) [10]. DS is a genetic change that impacts not only intellectual ability, but also motor development and motor control over the lifetime [11,12]. Abnormal brain functioning related to learning has been reveled in a number of studies [13][14][15][16]. In addition to neurodevelopmental abnormalities, corporal abnormalities are also common in DS. These abnormalities are highly related to the impaired motor control of voluntary movements [11,17].Children with DS require more time to learn basic movements. Additionally, as movement complexity increases they achieve gross motor functions at an average age that is almost twice that of typically developed children [18]. However, despite delays in motor development and the control of voluntary movements, the DS population does not exhibit a complete absence of the production of gross motor skills. For instance, individuals with DS are often capable of walking and jumping, as well as fine motor skills and manual dexterity. Examples of functional motor development can be seen when special teaching strategies are implemented [19][20][21][22][23][24]. This demonstrates that individuals with DS are at least somewhat able to adapt to their motor impairments. In more realistic tasks, Latash [11,17] argue that, when confronted with an unexpected or unclear motion situation, individuals with DS choose to act slowly (bradykinesia) during the initiation ph...

“…Indeed, it has been demonstrated that the walking direction of point-light walkers can be incidentally processed [37] and even induce reflexive attentional orienting [21], suggesting an intrinsic sensitivity of the human visual attention system to biological motion signals [17,38,39]. Because a fast moving biological entity is more likely to signal a threat, it is thus crucial for an organisms survival to quickly and precisely judge its moving direction in order to make an appropriate response (e.g., fight-or-flight reaction).…”

Motion speed modulates walking direction discrimination: The role of the feet in biological motion perception

et al. 2011

The human visual system is tuned to the motions of biological entities, which provide potentially vital information for survival. The current study examines the interplay between motion speed and motion direction perception. Following a brief presentation of a point-light walker walking straight ahead or slightly leftward or rightward, observers were asked to quickly judge the walking direction (left or right). Participants showed better direction discrimination when the walker walked at a fast pace compared to a natural or slow pace, and this was not simply due to a difference in motion cycles. Moreover, walking direction sensitivity could be enhanced by increasing the feet motion speed alone, so long as the direction of feet movement was consistent with that of the other body parts. These findings demonstrate that our perception of walking direction is influenced by local motion speed, and highlight the role of the feet in biological motion perception. biological motion, motion speed, walking direction, discrimination Citation:Cai P, Yang X Y, Chen L, et al.
