What's Up with High- and Low-Pitched Sounds? Reference Frames used in the Crossmodal Correspondence Between Auditory Pitch and Visuospatical Height
… Can low and high tones be used as spatial cues to upright for self-orientation? And what spatial frame(s) of reference is used to perceptually bind these crossmodal features? In experiment 1, participants’ Perceptual Upright (PU) was measured with and without presented auditory orientation …

Separating Component Signals of Episodic Simulation Using a Catch Trial Design
… disambiguated neural activity related to task orientation: i.e., preparing to remember events from the past or imagine events in the future) from activity related simulating events, per se. The current experiment uses functional MRI and employs a catch trial design to test the hypothesis that …

Top-down modulation of visual attention
This body of work examines the effects of pre-cues on visual search for targets defined by a colour-orientation conjunction. Cueing the identity of targets enhanced the efficiency of search, with stronger effects from cueing the colour of the target compared to cueing its orientation, even though …

Orchestration : the movement and vocal behavior of free-ranging Norwegian killer whales (Orcinus orca)
… activity and call types containing additional orientation cues. Tail slaps produced by tagged animals were identified using a rapid pitch change and occurred primarily within 20m of the surface. Two simultaneously tagged animals maneuvered similarly when tail slapping within 60s of one another, …

Movements, dive behavior and trophic ecology of leatherback turtles (Dermochelys coriacea) in the northwest Atlantic
… turtle tracks to examine migratory orientation cues of fifteen leatherbacks in the North Atlantic subtropical gyre. Individual leatherbacks were significantly oriented with no difference between adult and sub-adult headings, and turtles were significantly oriented with respect to …

Mechanisms of Compass Orientation in C57BL/6 Laboratory Mice
Compass orientation or menotaxis is defined as the ability to orient at a specific angle relative to a directional cue. Cues used for compass orientation include the sun, stars, moon, geomagnetic field and polarized light. While there is evidence in a variety of organisms for compass orientation, …

Effect of Age on Visual Dependence for Spatial Orientation and Postural Control
Effective spatial orientation and postural control requires the integration of proprioceptive, vestibular and visual inputs. Increased visual dependence has been reported in older adults but the underlying mechanisms remain unknown. The aims of this research were to investigate the methodological …

Training Wayfinding: Natural Movement In Mixed Reality
… to wirelessly track users' head position and orientation while presenting a graphic representation of their virtual surroundings, through which the user walked using natural movement. As previous studies have shown that virtual environments can be used to train navigation, the ability to add …
