Pseudoreplication in playback experiments, revisited a decade later

Animal Behaviour, 2001
Correspondence: D. E. Kroodsma, Department of Biology, University of Massachusetts, Amherst, MA 01003, U.S.A. (e-mail: kroodsma@bio.umass.edu). About 10 years ago, several papers in Animal Behaviour addressed the quality of experimental designs in ‘playback’ experiments (Kroodsma 1989a, b, 1990a, 1992; Searcy 1989; Weary & Mountjoy 1992), and this ...

Playback experiments: design and analysis

Acta ethologica, 2000
The scientific value of the outcome of an experiment is closely related to its design and analysis. This article deals with the design issues of pseudoreplication (whether the experimental design has the statistical features needed to answer the question as posed) and execution errors (problems arising from how the experiment was conducted).

Playback experiments for Thryothorus ludovicianus in urban backyard experiments

Journal of the Acoustical Society of America, 2015
Acoustic playback experiments were performed from June 2014 to April 2015 for Thryothorus ludovicianus (Carolina Wren) in a backyard environment in Austin, Texas. Acoustic recordings were made for pre-playback, playback, and post-playback periods for multiple song types.

Vibrational Playback Experiments: Challenges and Solutions

2014
Playbacks are one of the most useful experimental tools in animal communication research. Playbacks of substrate vibrations present special challenges, but conducting high-fidelity vibrational playbacks is not difficult and depends less on the specific equipment used than on avoiding some common pitfalls. We review the major issues, describing both the

Avian colour vision and avian video playback experiments

Acta ethologica, 2000
Video playback potentially allows the presentation, manipulation, and replication of realistic moving visual stimuli, in a way that is impossible with real animals or static dummies, and difficult even with mechanical models. However, there are special problems attached to the use of this technology; this article concentrates on the problem of accurate

Design of Playback Experiments: The Thornbridge Hall NATO ARW Consensus

1992
Playback is an experimental technique commonly used to investigate the significance of signals in animal communication systems. It involves replaying recordings of naturally occurring or synthesised signals to animals and noting their response. Playback has made a major contribution to our understanding of animal communication, but like any other ...

Primate Language and the Playback Experiment, in 1890 and 1980

Journal of the History of Biology, 2005
The playback experiment – the playing back of recorded animal sounds to the animals in order to observe their responses – has twice become central to celebrated researches on non-human primates. First, in the years around 1890, Richard Garner, an amateur scientist and evolutionary enthusiast, used the new wax cylinder phonograph to record and reproduce

Minke Whale (Balaenoptera Acutcrostrata) Response to a Sound Playback Experiment

2003
Abstract : A song playback experiment to singing minke whales on the Great Barrier Reef was carried out. Songs were played to singers at ranges of 0.5-2.0km A remotely monitored sonobuoy array was used to monitor whale movements and singing behavior.

Sound Playback Experiments with Southern Right Whales ( Eubalaena australis )

Science, 1980
A variety of sound recordings were played to southern right whales. Whales approached the loudspeaker and made frequent sounds in response to recordings of other southern right whales, but swam away and made relatively few sounds in response to playbacks of water noise, 200-hertz tones, and humpback whale sounds.
