“…Therefore, our results suggest that proprioception can provide only a gross orientation in space when we are walking along curved paths. This explanation agrees with others who suggested a similar role for proprioception for path integration [10,22–24]. …”

Path integration refers to the ability to integrate continuous information of the direction and distance travelled by the system relative to the origin. Previous studies have investigated path integration through blindfolded walking along simple paths such as straight line and triangles. However, limited knowledge exists regarding the role of path complexity in path integration. Moreover, little is known about how information from different sensory input systems (like vision and proprioception) contributes to accurate path integration. The purpose of the current study was to investigate how sensory information and curved path complexity affect path integration. Forty blindfolded participants had to accurately reproduce a curved path and return to the origin. They were divided into four groups that differed in the curved path, circle (simple) or figure-eight (complex), and received either visual (previously seen) or proprioceptive (previously guided) information about the path before they reproduced it. The dependent variables used were average trajectory error, walking speed, and distance travelled. The results indicated that (a) both groups that walked on a circular path and both groups that received visual information produced greater accuracy in reproducing the path. Moreover, the performance of the group that received proprioceptive information and later walked on a figure-eight path was less accurate than their corresponding circular group. The groups that had the visual information also walked faster compared to the group that had proprioceptive information. Results of the current study highlight the roles of different sensory inputs while performing blindfolded walking for path integration.

“…These data reinforce the notion that there are important individual differences in cognitive strategies during path integration (Israel et al, 2005; Siegler, 2000). In an experimental setting, the methodology might tend to make memory of the surrounding environment less salient (for example, because multiple trials are conducted without visual input, allowing the spatial memory to decay).…”

“…Instead, our current data demonstrate another crucial difference between verbal and pointing responses in the context of indications of angular displacement. Specifically, the frame of reference during whole-body rotations has a significant effect on the integration of incoming sensory signals (Israël et al, 2005; Siegler, 2000). In other words, incoming sensory signals during passive whole-body rotations may be directly integrated to yield a perception of self-motion and self-location estimates in egocentric-based terms, and as a result, spatial memory of the external environment is not needed.…”

The role of spatial memory and frames of reference in the precision of angular path integration

Angular path integration refers to the ability to maintain an estimate of self-location after a rotational displacement by integrating internally-generated (idiothetic) self-motion signals over time. Previous work has found that non-sensory inputs, namely spatial memory, can play a powerful role in angular path integration (Arthur et al., 2007, 2009). Here we investigated the conditions under which spatial memory facilitates angular path integration. We hypothesized that the benefit of spatial memory is particularly likely in spatial updating tasks in which one’s self-location estimate is referenced to external space. To test this idea, we administered passive, nonvisual body rotations (ranging 40° – 140°) about the yaw axis and asked participants to use verbal reports or open-loop manual pointing to indicate the magnitude of the rotation. Prior to some trials, previews of the surrounding environment were given. We found that when participants adopted an egocentric frame of reference, the previously-observed benefit of previews on within-subject response precision was not manifested, regardless of whether remembered spatial frameworks were derived from vision or spatial language. We conclude that the powerful effect of spatial memory is dependent on one’s frame of reference during self-motion updating.

“…For professional classical dancers, the high variability noted when they return to the start position during passive sitting body rotations of 270° (completion) shows a deficiency in integrating vestibular signals for updating the egocentric representation of an external target. That finding suggests a preference for the allocentric strategy, whereas the seated position in rotation was slower than a pirouette (Israel, Lecoq, Capelli, & Golomer, 2005). This assessment needs to be verified, correlating these results with those obtained in an upright position during a pirouette, which is quicker and does not involve the vestibular system and the other spatial references in the same way.…”

To analyze individual behavior in spatial navigation especially for pirouette preparations (complete whole-body rotations), the authors studied horizontal shoulder-hip interactions under 2 constraints: postural (right and left supporting legs [SL]) and spatial (clockwise [CW] and counterclockwise [CCW]). They performed kinematic analysis at the start and end of the shoulder-hip horizontal rotations (run-up) with regard to imagery of motor actions. On the basis of the Vividness of Movement Imagery Questionnaire, they classified 8 female expert ballet dancers and 7 untrained female participants according to their movement imagery style (kinesthetic and visual). At the run-up's end, the shoulders initiated the turn independently of SL but differently depending on training: CW for dancers and CCW for untrained participants (their commonly used direction). Kinesthetic and mixed imagery styles prevailed in dancers, whereas simply a mixed style appeared among untrained participants. Thus, dance training enhances the imagery of kinesthetic sensation and influences the choice of spatial direction, facilitating the body-space interaction.
