Abstract We quantified foraging rates and foraging visibility metrics for four Neotropical warblers—Slate-throated Redstart (Myoborus miniatus), Golden-crowned Warbler (Basileuterus culicivorus), Wilson's Warbler (Wilsonia pusilla), and Black-and-White Warbler (Mniotilta varia)—under flocking and solitary conditions in western Panama to test hypotheses regarding the relative influences of predation pressure and social facilitation on foraging behavior. We also compared foraging behavior in primary forests and in traditionally managed shade coffee fields for two species (Slate-throated Redstart

Abstract:
The use of three-dimensional auditory technology which provides localization of auditory cues presented through headphones is proposed as a means of providing supplemental information to pilots on the spatial orientation of an aircraft. This technique shows promise for reducing accidents due to spatial disorientation associated with high visual load. A study was conducted using Air Force pilots as subjects to determine desirable cue characteristics for accurately localizing auditory cues using this technique. The study examined the use of nine different cue types at each of two frequency level

Abstract:
Real-world objects are complex, containing information at multiple orientations and spatial scales. It is well established that at initial cortical stages of processing, local information about an image is separately represented at multiple spatial scales. However, it is not yet established how these early representations are later integrated across scale to signal useful information about complex stimulus features, such as edges and textures. In the studies reported here, we investigate the scale-integration processes involved in distinguishing among complex patterns. We use a concurrent-resp

Abstract:
This article proposes three control algorithms for the emergence of self-organized behaviours, including aggregation, flocking and rendezvous, in swarm robotics systems. The proposed control algorithms are based on a local polar coordinates’ control law available in the literature for posture regulation; this law is adapted to work in a self-organized robotic swarm using distance and bearing as coupling information. Therefore, the robots only need to know the radial distance and orientation to the goal; additionally, the three algorithms are based on self-organization, eliminating the need for

Abstract:
To localize objects relative to ourselves, we need to combine various sensory and motor signals. When these signals change abruptly, as information about eye orientation does during saccades, small differences in latency between the signals could introduce localization errors. We examine whether independent temporal information can influence such errors. We asked participants to follow a randomly jumping dot with their eyes and to point at flashes that occurred near the time they made saccades. Such flashes are mislocalized. We presented a tone at different times relative to the flash. We foun

Dependent measures included memory for items, order, and response latency. The presence of a spatial cue had a significant effect on memory for order but not on memory for an item. For response latency, there were significant main effects for visual field and direction. There were also several significant interactions of visual field, direction, and orientation.

Features can be used in a second and separate step, but only to locate a goal rather than as a reorientation cue.

Abstract:
AbstractSeveral behavioral studies show that semantic content influences reach-to-grasp movement responses. However, not much is known about the influence of motor activation on semantic processing. The present study aimed at filling this gap by examining the influence of pre-activated motor information on a subsequent lexical decision task. Participants were instructed to observe a prime object (e.g., the image of a frying pan) and then judge whether the following target was a known word in the lexicon or not. They were required to make a keypress response to target words describing properties either relevant (e.g., handle) or irrelevant (e.g., ceramic) for action or unrelated to the prime object (e.g., eyelash). Response key could be located on the same side as the depicted action-relevant property of the prime object (i.e., spatially compatible key) or on the opposite side (i.e., spatially incompatible key). Results showed a facilitation in terms of lower percentage errors when the target word was action-relevant (e.g., handle) and there was spatial compatibility between the orientation of the action-relevant component of the prime object and the response. This preliminary finding suggests that the activation of motor information may affect semantic processing. We discuss implications of these results for current theories of action knowledge representation.

Abstract:
AbstractIn recent years, assistive technology and digital accessibility for blind and visually impaired people (BVIP) has been significantly improved. Yet, group discussions, especially in a business context, are still challenging as non-verbal communication (NVC) is often depicted on digital whiteboards, including deictic gestures paired with visual artifacts. However, as NVC heavily relies on the visual perception, whichrepresents a large amount of detail, an adaptive approach is required that identifies the most relevant information for BVIP. Additionally, visual artifacts usually rely on spatial properties such as position, orientation, and dimensions to convey essential information such as hierarchy, cohesion, and importance that is often not accessible to the BVIP. In this paper, we investigate the requirements of BVIP during brainstorming sessions and, based on our findings, provide an accessible multimodal tool that uses non-verbal and spatial cues as an additional layer of information. Further, we contribute by presenting a set of input and output modalities that encode and decode information with respect to the individual demands of BVIP and the requirements of different use cases.
