Comparing passive and active hearing: spectral analysis of transient sounds in bats.

In vision, colour constancy allows the evaluation of the colour of objects independent of the spectral composition of a light source. In the auditory system, comparable mechanisms have been described that allows the evaluation of the spectral shape of sounds independent of the spectral composition of ambient background sounds. For echolocating bats, the evaluation of spectral shape is vitally i...

The Effects of Cooperative Language Learning Strategies on Learning Active and Passive Structures among Iranian EFL Learners

This study aims at investigating the effects of cooperative language learning on learning active and passive structures among Iranian EFL students. The participants of the study were 60 high school students that were selected from third grade of Barikbin high school in Qazvin. All of the participants were male. Their level of proficiency was intermediate. Then the participants were divided into...

Broadband noise exposure does not affect hearing sensitivity in big brown bats (Eptesicus fuscus).

In many vertebrates, exposure to intense sounds under certain stimulus conditions can induce temporary threshold shifts that reduce hearing sensitivity. Susceptibility to these hearing losses may reflect the relatively quiet environments in which most of these species have evolved. Echolocating big brown bats (Eptesicus fuscus) live in extremely intense acoustic environments in which they navig...

Study of Numerical Processing Speed, Implicit and Explicit Memory, Active and Passive Memory, Conservation Abilities, and Visual-Spatial Skills of Students with Dyscalculia

Background and Purpose: Learning disorder is one of the common disorders in students, which can lead to the occurrence of educational problems and secondary disorders in them. Based on psychopathological criteria, dyscalculia is one of the subcategories of learning disorder. Children with this disorder have problems in perception of spatial relations and in different cognitive abilities. Theref...

Delayed Response and Biosonar Perception Explain Movement Coordination in Trawling Bats

Animal coordinated movement interactions are commonly explained by assuming unspecified social forces of attraction, repulsion and alignment with parameters drawn from observed movement data. Here we propose and test a biologically realistic and quantifiable biosonar movement interaction mechanism for echolocating bats based on spatial perceptual bias, i.e. actual sound field, a reaction delay,...
