“…Fragaszy and Mangalam (2018) stress the need for immediate contact with grasping skin or target surface, but cascade-driven interactions allow no straightforward segregation of short-range interaction from more distal forces. Rather than an empty expanse, environmental space is full of clutter whose integral flow supports organisms via contact through distributed-but-rarely-distinct modalities (e.g., optical, acoustic, and haptic (1979), Pittenger (1995), andHarrison et al (2021), respectively). The specificity of localized sensor cells is physiologically real, but they distract from the non-exclusivity and often mutuality of manipulation and, say, observation when mechanical contact is lost (Stoffregen et al, 2017).…”

The ubiquity of tool use in human life has generated multiple lines of scientific and philosophical investigation to understand the development and expression of humans' engagement with tools and its relation to other dimensions of human experience. However, existing literature on tool use faces several epistemological challenges in which the same set of questions generate many different answers. At least four critical questions can be identified, which are intimately intertwined-(1) What constitutes tool use? (2) What psychological processes are involved in tool use? (3) Which of these psychological processes are specific to tool use? (4) Which psychological processes involved in tool use are specific to Homo sapiens? To help advance a multidisciplinary scientific understanding of tool use, six author groups representing different academic disciplines (e.g., anthropology, psychology, neuroscience) and different theoretical perspectives respond to each of these questions, and then point to the direction of future work on tool use. We find that while there are marked differences among the responses of the respective author groups to each question, there is a-perhaps surprisingdegree of agreement about many essential concepts and questions. We believe that this interdisciplinary and intertheoretical discussion will foster a more comprehensive understanding of tool use than any one of these perspectives (or any one of these author groups) would (or could) on their own.

“…When actively traversing (e.g., walking through) an environment, multiple sources of information about self-motion are redundantly available. This includes visual information (Ellmore & McNaughton, 2004), vestibular information (Israel et al, 1997;Mittelstaedt, 1999), and podokinetic information (Glasauer et al 1994(Glasauer et al , 2002Harrison et al, 2021). Podokinetic information refers to the information that is created by the movements of the legs during locomotion (Weber et al, 1998).…”

“…Running Head: PODOKINETIC PATH INTEGRATION FOR CRAWLING GAITS 4 Path integration based upon podokinetic information has been investigated in a set of gait manipulation experiments in which direct-route homing tasks have been performed without vision (e.g., while blindfolded) and the gait patterns and gait parameters used in the outbound and inbound phases of the task have been systematically manipulated (Abdolvah et al, 2015;Harrison, 2020;Harrison et al, 2021;Isenhower et al, 2012;Schwartz, 1999;Turvey et al, 2009;. These gait manipulation experiments have repeatedly shown that the podokinetic information supporting path integration is not associated with simple lower-order variables, such as the number of steps, elapsed time, or the energy expended during outbound and inbound travel.…”

Self-motion can be perceived via podokinetic information, that is, based upon the movements of the legs during legged locomotion. This information can be integrated in order to perceive a path of travel through the environment (i.e., via podokinetic path integration). Two types of podokinetic information have been distinguished by analyzing the patterns of bias that result from manipulating the gait patterns used in direct-route homing tasks. Each type of podokinetic information has been associated specific groupings of gaits that support equivalent perceptual measurements of self-motion. Specifically, gaits are grouped if they can be varied across the outbound and inbound phases of a homing task (e.g., walking outbound and jogging inbound) and the accuracy of homing task performances does not differ from matched gait control conditions.Recently, it was theorized that different types of podokinetic information are related to the differences in the kinematic form of limb motions in these groupings of gaits. Here we test an alternative hypothesis, namely, that attention plays a role in selecting the type of podokinetic information. In three experiments we manipulated the crawling gait patterns used in direct-route homing tasks. Consistent with our hypotheses, we observe that selfmotion is equivalently measured via crawling movement patterns that 1) have distinct kinematic forms, but that similarly direct participants' attention onto controlling the swing phase trajectories of their arms, and 2) have distinct inter-limb coordination patterns (i.e., pace vs. trot), but do not require attention to be specifically focused upon swing phase arm trajectories.

“…Successful navigation through an environment requires the accurate estimation of one’s traveled distance (path integration) and direction of self-motion (heading). Previous studies have documented the role of visual ( 1 ), vestibular ( 2 ), auditory ( 3 ), and tactile ( 4 , 5 ) information for the processing of traveled distance. Studies on heading perception have mainly focused on visual (e.g., Ref.…”

Self-motion through an environment induces various sensory signals, i.e., visual, vestibular, auditory, or tactile. Numerous studies have investigated the role of visual and vestibular stimulation for the perception of self-motion direction (heading). Here, we investigated the rarely considered interaction of visual and tactile stimuli in heading perception. Participants were presented optic flow simulating forward self-motion across a horizontal ground plane (visual) or airflow towards the participants' forehead (tactile), or both. In separate blocks of trials, participants indicated perceived heading from unimodal visual, tactile, or bimodal sensory signals. In bimodal trials, presented headings were either spatially congruent or incongruent with a maximum offset between visual and tactile heading of 30°. To investigate the reference frame in which visuo-tactile heading is encoded, we varied head and eye orientation during presentation of the stimuli. Visual and tactile stimuli were designed to achieve comparable heading accuracies between modalities. Nevertheless, in bimodal trials, heading perception was dominated by the visual stimulus. A change of head orientation had no significant effect on perceived heading, while, surprisingly, a change in eye orientation affected tactile heading perception. Overall, we conclude that tactile flow is more important to heading perception than previously thought.
