Cognitive Abilities in Human Echolocation
The human ability to echolocate differs between individuals. Blind perform significantly better then sighted. There is very limited research on psychological factors underlying this ability. This study is based on earlier research by Schenkman and Nilsson (2010). The research questions in the present study were whether blind individuals perform better then sighted on general cognitive tasks, if...
متن کاملA Device for Human Ultrasonic Echolocation
Representing and interacting with the external world constitutes a major challenge for persons who are blind or visually impaired. Often, non-visual sensory modalities such as audition and somato-sensation acquire increased importance in sampling the environment. In many non-human species operating without vision, this is achieved by active echolocation, in which acoustic pulses are emitted and...
متن کاملEcholocation
in their length can quantitatively explain the dynamic range of all helical and non-helical cell geometries. The purified, detergent insoluble cytoskeleton complex from spiroplasmas contains over ten proteins, the main one being a 59 kDa product of the fib gene with no known prokaryotic or eukaryotic homologs. Infectivity in spiroplasmas is governed by an unusual lipoprotein, spiralin, which co...
متن کاملNeural Correlates of Natural Human Echolocation in Early and Late Blind Echolocation Experts
BACKGROUND A small number of blind people are adept at echolocating silent objects simply by producing mouth clicks and listening to the returning echoes. Yet the neural architecture underlying this type of aid-free human echolocation has not been investigated. To tackle this question, we recruited echolocation experts, one early- and one late-blind, and measured functional brain activity in ea...
متن کاملNeural Correlates of Human Echolocation of Path Direction During Walking.
Echolocation can be used by blind and sighted humans to navigate their environment. The current study investigated the neural activity underlying processing of path direction during walking. Brain activity was measured with fMRI in three blind echolocation experts, and three blind and three sighted novices. During scanning, participants listened to binaural recordings that had been made prior t...
