execute an accurate and fast blocking movement, especially at higher levels of competition where faster gameplay creates greater time constraints ( Panfil & Superlak, 2012 ). Successful decision-making when blocking requires exceptional levels of two performance elements, perception–action coupling and

The quiet-eye (QE) phenomenon has been found to predict subsequent motor performance. However, it remains unclear whether this effect also holds for considerably extended QE durations. Therefore, in 2 ball-throwing studies, QE durations of 400–3,200 ms were experimentally induced. Inferior performance was found in short QE-duration conditions; however, there was no difference between the long QE-duration conditions. Extrapolations beyond the observed QE values showed performance gains up to 2,000 ms and a shallow interval of optimality at a QE duration of about 3,000 ms. These results, together with the fact that the intended absolute QE durations were not achieved, point toward an inhibition explanation of the QE. Thus, the initial performance gain is interpreted as shielding of the movement parameterization against suboptimal alternatives, whereas the performance loss due to very long QE durations is ascribed to mutually balancing the processes of shielding and environmental monitoring.

In this opinion paper, we aim to delineate the development of the person–object differentiation in visuomotor behavior as established during the first two years of life, which can be conceived as a precursor for the broader distinction between animate and inanimate entities, which in turn form the basis of the more inclusive biological–nonbiological distinction (Poulin-Dubois, Lepage, & Ferland, 1996). We then discuss embodied sensorimotor simulation, which allows us to use the self as a model for perceiving objects in our environment, as a potential mechanism underlying this distinction.

This study used a virtual, simulated 3 vs. 3 rugby task to investigate whether gaps opening in particular running channels promote different actions by the ball carrier player and whether an effect of rugby expertise is verified. We manipulated emergent gaps in three different locations: Gap 1 in the participant’s own running channel, Gap 2 in the first receiver’s running channel, and Gap 3 in the second receiver’s running channel. Recreational, intermediate, professional, and nonrugby players performed the task. They could (i) run with the ball, (ii) make a short pass, or (iii) make a long pass. All actions were digitally recorded. Results revealed that the emergence of gaps in the defensive line with respect to the participant’s own position significantly influenced action selection. Namely, “run” was most often the action performed in Gap 1, “short pass” in Gap 2, and “long pass” in Gap 3 trials. Furthermore, a strong positive relationship between expertise and task achievement was found.

Infants show a dramatic shift in postural and emotional responsiveness to peripheral lamellar optic flow (PLOF) following crawling onset. The present study used a novel virtual moving room to assess postural compensation of the shoulders backward and upward and heart rate acceleration to PLOF specifying a sudden horizontal forward translation and a sudden descent down a steep slope in an infinitely long virtual tunnel. No motion control conditions were also included. Participants were 53 8.5-month-old infants: 25 prelocomotors and 28 hands-and-knees crawlers. The primary findings were that crawling infants showed directionally appropriate postural compensation in the two tunnel motion conditions, whereas prelocomotor infants were minimally responsive in both conditions. Similarly, prelocomotor infants showed nonsignificant changes in heart rate acceleration in the tunnel motion conditions, whereas crawling infants showed significantly higher heart rate acceleration in the descent condition than in the descent control condition, and in the descent condition than in the horizontal translation condition. These findings highlight the important role played by locomotor experience in the development of the visual control of posture and in emotional reactions to a sudden optically specified drop. The virtual moving room is a promising paradigm for exploring the development of perception–action coupling.

This study investigated whether 5- to 11-year-old children perceive affordances in the same way as adults (M age = 22.93, SD = 2.16) when presented with a task and four tools (nail in a block of wood and a hammer, rock, wrench, and comb; bucket of sand and a shovel, wooden block, rake, and tweezers; and a screw in a block of wood and a screwdriver, knife, dime, and crayon). Participants were asked to select the best tool and act on an object until all four assigned tools had been selected. No explicit instructions were provided because we were interested in how task perception would influence tool selection and action. Results support the notion that the capacity to perceive affordances increases with age. Furthermore, differences in the way in which 5-year-olds acted on the screw in a block of wood demonstrated that the ability to detect some affordances takes longer to refine. Findings help to further the understanding of the development of perception-action coupling.

Making contact with the ball when receiving a serve is a refined skill that requires years of practice ( Goulet, Bard, & Fleury, 1989 ). Superior hand–eye coordination and perception–action coupling enable the motor system to make contact with a fast-approaching ball, a feat that challenges the
