Embodied choices bypass narratives under radical uncertainty.

Johnson et al. suggest that we rely on narratives to make choices under radical uncertainty. We argue that in its current version Conviction Narrative Theory (CNT) does not account for embodied, direct sensorimotor influences on choices under radical uncertainty that may bypass narratives, particularly in highly time-constrained situations. We therefore suggest to extend CNT by an embodied choice perspective

Let’s do the time warp again – embodied learning of the concept of time in an applied school setting

This article has been accepted for publication in Interactive Learning Environments, published by Taylor & Francis. Embodied Cognition approaches suggest that movements influence the understanding of abstract concepts such as time. It follows that moving the arms as watch hands should boost children’s learning to read the clock. In a school setting, we compared three learning conditions: an embodied (movement) condition, an interactive App condition, and a text condition. Age, self-reported enjoyment, and group size were controlled. In a clock-time-test, the embodied condition resulted in better performances than the mean of the other conditions in small, but not in large groups. This innovative, theory-informed approach may advance learning of abstract concepts in children

Spatial distances affect temporal prediction and interception.

The more distant two consecutive stimuli are presented, the longer the temporal interstimulus interval (ISI) between their presentations is perceived (kappa effect). The present study aimed at testing whether the kappa effect not only affects perceptual estimates of time, but also motor action, more specifically, interception. In a first step, the original kappa paradigm was adapted to assess the effect in temporal prediction. Second, the task was further modified to an interception task, requiring participants to spatially and temporally predict and act. In two online experiments, a white circle was successively presented at three locations moving from left to right with constant spatial and temporal ISIs in between. Participants were asked to either (i) indicate the time of appearance of the predicted fourth stimulus (Exp. 1) or to (ii) intercept the predicted fourth location at the correct time (Exp. 2). In both experiments the temporal response depended on the spatial intervals. In line with the kappa effect, participants predicted the final stimulus to appear later (Exp. 1) or intercepted it later (Exp. 2), the more distant the stimuli were presented. Together, these results suggest that perceptual biases such as the kappa effect impact motor interception performance. [Abstract copyright: © 2022. The Author(s).

Aufmerksamkeitsfokus und visuelle Selektion im Sport

Die vorliegende Arbeit hat sich mit Fragen zum Aufmerksamkeitsfokus und zur visuellen Informationsselektion in sportartspezifischen Entscheidungssituationen auseinander gesetzt. Auf der Grundlage einer technisch-methodisch sowie zwei weiteren inhaltlich-theoretisch motivierten Fragestellungen wurden drei übergeordnete Experimente durchgeführt, die methodisch einerseits auf dem Hinweisreizparadigma und andererseits auf dem Flicker-Cueing Paradigma basierten. Die Ergebnisse der Arbeit zeigen erstens, dass das Hinweisreizparadigma nicht auf die Untersuchung visueller Aufmerksamkeitsprozesse in sportartspezifischen Entscheidungssituationen übertragen werden kann. Zweitens scheint Flicker Cueing als visuelle Form der Aufmerksamkeitslenkung effektiver zu sein als verbale Instruktionen. Drittens scheinen frequente Flicker in videobasierten Entscheidungstrainings ihre Fähigkeit, die Aufmerksamkeit exogen zu lenken, aufgrund von Gewöhnungseffekten zu verlieren

A Lifespan Perspective on Embodied Cognition

Since its infancy embodied cognition research has fundamentally changed our understanding of how action, perception, and cognition relate to and interact with each other. Ideas from different schools of thought have led to controversial theories and a unifying framework is still being debated. In this perspective paper, we argue that in order to improve our understanding of embodied cognition and to take significant steps toward a comprehensive framework, a lifespan approach is mandatory. Given that most established theories have been developed and tested in the adult population, which is characterized by relatively robust and stable sensorimotor and cognitive abilities, we deem it questionable whether embodied cognition effects found in this population are representative for different life stages such as childhood or the elderly. In contrast to adulthood, childhood is accompanied by a rapid increase of sensorimotor and cognitive skills, and the old age by a decline of such capacities. Hence, sensorimotor and cognitive capacities, as well as their interactions, are more fragile at both extremes of the lifespan, thereby offering a unique window into the emergence of embodied cognition effects and age-related differences therein. A lifespan approach promises to make a major contribution toward a unifying and comprehensive theory of embodied cognition that is valid across the lifespan and ‘gets better with age.

Walking back to the future: The impact of walking backward and forward on spatial 2 and temporal concepts

Embodied cognition frameworks suggest a direct link between sensorimotor experience and cognitive representations of concepts (Shapiro, 2011). We examined whether this holds also true for concepts that cannot be directly perceived with the sensorimotor system (i.e., temporal concepts). To test this, participants learned object–space (Exp. 1) or object–time (Exp. 2) associations. Afterwards, participants were asked to assign the objects to their location in space/time meanwhile they walked backward, forward, or stood on a treadmill. We hypothesized that walking backward should facilitate the on-line processing of ”behind”/“past”-related stimuli, but hinder the processing of “ahead”/“future”-related stimuli, and a reversed effect for forward walking. Indeed, “ahead”- and “future”-related stimuli were processed slower during backward walking. During forward walking and standing, stimuli were processed equally fast. The results provide partial evidence for the activation of specific spatial and temporal concepts by whole-body movements and are discussed in the context of movement familiarity

Effects of visual blur and contrast on spatial and temporal precision in manual interception.

The visual system is said to be especially sensitive towards spatial but lesser so towards temporal information. To test this, in two experiments, we systematically reduced the acuity and contrast of a visual stimulus and examined the impact on spatial and temporal precision (and accuracy) in a manual interception task. In Experiment 1, we blurred a virtual, to-be-intercepted moving circle (ball). Participants were asked to indicate (i.e., finger tap) on a touchscreen where and when the virtual ball crossed a ground line. As a measure of spatial and temporal accuracy and precision, we analyzed the constant and variable errors, respectively. With increasing blur, the spatial and temporal variable error, as well as the spatial constant error increased, while the temporal constant error decreased. Because in the first experiment, blur was potentially confounded with contrast, in Experiment 2, we re-ran the experiment with one difference: instead of blur, we included five levels of contrast matched to the blur levels. We found no systematic effects of contrast. Our findings confirm that blurring vision decreases spatial precision and accuracy and that the effects were not mediated by concomitant changes in contrast. However, blurring vision also affected temporal precision and accuracy, thereby questioning the generalizability of the theoretical predictions to the applied interception task.

Interrelations between temporal and spatial cognition: The role of modality-specific processing

© 2018 Loeffler, Cañal-Bruland, Schroeger, Tolentino-Castro and Raab. Temporal and spatial representations are not independent of each other. Two conflicting theories provide alternative hypotheses concerning the specific interrelations between temporal and spatial representations. The asymmetry hypothesis (based on the conceptual metaphor theory, Lakoffand Johnson, 1980) predicts that temporal and spatial representations are asymmetrically interrelated such that spatial representations have a stronger impact on temporal representations than vice versa. In contrast, the symmetry hypothesis (based on a theory of magnitude, Walsh, 2003) predicts that temporal and spatial representations are symmetrically interrelated. Both theoretical approaches have received empirical support. From an embodied cognition perspective, we argue that taking sensorimotor processes into account may be a promising steppingstone to explain the contradictory findings. Notably, different modalities are differently sensitive to the processing of time and space. For instance, auditory information processing is more sensitive to temporal than spatial information, whereas visual information processing is more sensitive to spatial than temporal information. Consequently, we hypothesized that different sensorimotor tasks addressing different modalities may account for the contradictory findings. To test this, we critically reviewed relevant literature to examine which modalities were addressed in time-space mapping studies. Results indicate that the majority of the studies supporting the asymmetry hypothesis applied visual tasks for both temporal and spatial representations. Studies supporting the symmetry hypothesis applied mainly auditory tasks for the temporal domain, but visual tasks for the spatial domain. We conclude that the use of different tasks addressing different modalities may be the primary reason for (a)symmetric effects of space on time, instead of a genuine (a)symmetric mapping

Kissing right? On the consistency of the head-turning bias in kissing

The present study investigated the consistency of the head-turning bias in kissing. In particular we addressed what happens if a person who prefers to kiss with the head turned to the right kisses a person who prefers to kiss with the head turned to the left. To this end, participants (N=57) were required to kiss a life-sized doll's head rotated in different orientations that were either compatible or incompatible with the participants' head-turning preference. Additionally, participants handedness, footedness, and eye preference was assessed. Results showed that a higher percentage of participants preferred to kiss with their head turned to the right than to the left. In addition, the right-turners were more consistent in their kissing behaviour than left-turners. That is, with the doll's head rotated in an incompatible direction, right-turners were less likely to switch their head to their non-preferred side. Since no clear relationships between head-turning bias and the other lateral preferences (i.e., handedness, footedness, and eye preference) were discerned, the more consistent head-turning bias among right-turners could not be explained as deriving from a joint pattern of lateral preferences that is stronger among individuals with rightward as compared to individuals with leftward lateral preferences. © 2010 Psychology Press

Deceptive body movements reverse spatial cueing in soccer

This article has been made available through the Brunel Open Access Publishing Fund.The purpose of the experiments was to analyse the spatial cueing effects of the movements of soccer players executing normal and deceptive (step-over) turns with the ball. Stimuli comprised normal resolution or point-light video clips of soccer players dribbling a football towards the observer then turning right or left with the ball. Clips were curtailed before or on the turn (-160, -80, 0 or +80 ms) to examine the time course of direction prediction and spatial cueing effects. Participants were divided into higher-skilled (HS) and lower-skilled (LS) groups according to soccer experience. In experiment 1, accuracy on full video clips was higher than on point-light but results followed the same overall pattern. Both HS and LS groups correctly identified direction on normal moves at all occlusion levels. For deceptive moves, LS participants were significantly worse than chance and HS participants were somewhat more accurate but nevertheless substantially impaired. In experiment 2, point-light clips were used to cue a lateral target. HS and LS groups showed faster reaction times to targets that were congruent with the direction of normal turns, and to targets incongruent with the direction of deceptive turns. The reversed cueing by deceptive moves coincided with earlier kinematic events than cueing by normal moves. It is concluded that the body kinematics of soccer players generate spatial cueing effects when viewed from an opponent's perspective. This could create a reaction time advantage when anticipating the direction of a normal move. A deceptive move is designed to turn this cueing advantage into a disadvantage. Acting on the basis of advance information, the presence of deceptive moves primes responses in the wrong direction, which may be only partly mitigated by delaying a response until veridical cues emerge
