“…As stated in the introduction section, an eect of optical size and expansion rate has been observed in tasks where CBA strategy is known to provide a good account for participants behavior (Chardenon et al, 2004;de Rugy et al, 2001). In those studies it has been shown that optical expansion did impact participants' behavior although the eect was of a moderated importance and was taking place at the end of the trial.…”

“…This hypothesis would be consistent with interception studies showing a marginal yet demonstrated eect of target's optical size and rate of expansion. For instance, Chardenon et al (2004);de Rugy et al (2001) showed that target's optical expansion inuences participants' speed adjustments, particularly at the end of the trials where participants decreased their approach speed for high target's optical expansion rate.…”

“…For some of these studies, the target has only appeared moments before the required step (e.g. [14]) or has been incorporated into specific laboratory equipment, such as treadmills [15] or virtual reality systems [12]. By incorporating a task that involves an every-day activity, the current study aimed to generalize the findings of previous locomotor pointing research [2,13] to everyday situations.…”

Perceptual-motor regulation in locomotor pointing while approaching a curb

2018

Locomotor pointing is a task that has been the focus of research in the context of sport (e.g. long jumping and cricket) as well as normal walking. Collectively, these studies have produced a broad understanding of locomotor pointing, but generalizability has been limited to laboratory type tasks and/or tasks with high spatial demands. The current study aimed to generalize previous findings in locomotor pointing to the common daily task of approaching and stepping on to a curb. Sixteen people completed 33 repetitions of a task that required them to walk up to and step onto a curb. Information about their foot placement was collected using a combination of measures derived from a pressure-sensitive walkway and video data. Variables related to perceptual-motor regulation were analyzed on an inter-trial, intra-step and inter-step level. Similar to previous studies, analysis of the foot placements showed that, variability in foot placement decreased as the participants drew closer to the curb. Regulation seemed to be initiated earlier in this study compared to previous studies, as shown by a decreasing variability in foot placement as early as eight steps before reaching the curb. Furthermore, it was shown that when walking up to the curb, most people regulated their walk in a way so as to achieve minimal variability in the foot placement on top of the curb, rather than a placement in front of the curb. Combined, these results showed a strong perceptual-motor coupling in the task of approaching and stepping up a curb, rendering this task a suitable test for perceptual-motor regulation in walking.

“…An alternative methodology is to examine modifications in behavior when a specific property is gradually modified during the trial. Within-trial manipulations are commonly applied in studies that aim to identify perceptual-motor mechanisms in interceptive tasks [ 17 ], heading tasks [ 18 ], and locomotor pointing tasks [ 19 ]. We believe that within-trial manipulations may also help to identify the perceptual-motor strategies used by pilots.…”

Eye position affects flight altitude in visual approach to landing independent of level of expertise of pilot

The present study addresses the effect of the eye position in the cockpit on the flight altitude during the final approach to landing. Three groups of participants with different levels of expertise (novices, trainees, and certified pilots) were given a laptop with a flight simulator and they were asked to maintain a 3.71° glide slope while landing. Each participant performed 40 approaches to the runway. During 8 of the approaches, the point of view that the flight simulator used to compute the visual scene was slowly raised or lowered with 4 cm with respect to the cockpit, hence moving the projection of the visible part of the cockpit down or up in the visible scene in a hardly noticeable manner. The increases and decreases in the simulated eye height led to increases and decreases in the altitude of the approach trajectories, for all three groups of participants. On the basis of these results, it is argued that the eye position of pilots during visual approaches is a factor that contributes to the risk of black hole accidents.
