Categorical Perception of Sound Frequency by Crickets
Categorical perception was tested in crickets by using two paradigms of human psychophysics, labeling and habituation-dishabituation, and the results show that crickets divide sound frequency categorically between attractive and repulsive sounds. Expand
Ultrasound-triggered, flight-gated evasive maneuvers in the praying mantis Parasphendale agrionina. I. Free flight.
Free-flying male praying mantises Parasphendale agrionina (Gerst.) perform evasive maneuvers when stimulated by ultrasound and when attacked by hunting, echolocating bats. They do not, however,Expand
Multisegmental analyses of acoustic startle in the flying cricket (Teleogryllus oceanicus): kinematics and electromyography.
Tethered, flying Australian field crickets stimulated with ultrasound respond with a rapid, short-latency turn from the sound source, and the kinematics of two behavioral components of this acoustic startle response are analyzed and electromyograms from the muscles involved in producing them are recorded to relate them to the relevance of the two behavior patterns to the execution of an escape response.

Ultrasound-triggered, flight-gated evasive maneuvers in the praying mantis Parasphendale agrionina. II. Tethered flight.
Several components of the in-flight evasive behavior resemble defensive displays on the ground, and it is suggested that this mantis has responded to predation pressure from bats with both flight-derived maneuvers and an aerial deimatic display. Expand

An ultrasonic stimulus induced negative phonotactic steering in the yaw axis of tethered, flying Australian field crickets, revealing that this behavior is more complex than a simple reflex. Expand
Kinematic and aerodynamic aspects of ultrasound-induced negative phonotaxis in flying Australian field crickets (Teleogryllus oceanicus)
Ultrasound induces flying crickets to roll away from the stimulus source location and this behavioral complexity lends further credence to the hypothesis that cricket negative phonotaxis provides a valuable function, perhaps as a bat avoidance response. Expand
The requirement for ROVs to perform ever more demanding tasks and the extension of their use into deeper waters has resulted in a need for a method of synthesising design solutions and assessingExpand
