Retinal speed did not correlate well with the actual risk of predation because it confounded a predator's direction of approach with its speed and proximity.
Under such empirical analysis, the zero-adjusted inverse Gaussian distribution is appropriate to reflect the distributional characteristics of crash rates and provide a new direction of approaches in the field of crash data analyses.
Although vision can in principle provide instant information on a predator's position, direction of approach and identity, prey animals that face fast predators have to respond so early (close to the limits of detection) that visual cues are unreliable predictors of actual risk.
A careful review of the geometry of the engagement will reveal that even a moderately skewed off-frontal direction of approach will drastically reduce the chances that fragments from the Iron Dome warhead could be sprayed onto the warhead of the artillery rocket.
(1) Motor constraints Iconic gesturing may be rare because it is mechanically easier for an ape to depict a movement in space (e.g. direction of approach, location of desired grooming ), than to pantomime other types of activities.
The fruit fly can plan an escape trajectory that takes into account both its initial posture and the direction of approach of a looming stimulus.
As discussed in the introduction, Howell [5] measured the "threshold distance" at which an aircraft (DC-3) could be detected by a vigilant observer precisely aware of the direction of approach.
The safest place is the side or corner of an underground room opposite the tornado's direction of approach (usually the northeast corner), or the central-most room on the lowest floor.
As for Midway -- in which the Americans enjoyed knowledge of "enemy objective, timing, strength, direction of approach, launch position," and scored an impressive victory -- he insists that it was not a pure intelligence victory, as some have contended, but a victory in which chance played an equally important role.
The Passions may be seen as a continuation of the Treatise of man, except that the direction of approach is different.
The variation of perceived orientation with gaze angle could reflect a neural gain field effect, but could also be attributable to the direction of approach to the target, - the proximal face being closer to the fovea and therefore enjoy a competitive advantage in representing a visible cube face.
