The Use of Playbacks in Behavioral Experiments
2019Playback is a ubiquitous technique for the controlled manipulation and presentation of animal signals, and has become an invaluable tool in the study of animal communication. Playback stimuli can be manipulated or unmanipulated samples of natural signals, or they can be mathematically constructed de novo based on models of signal structure or signal ...

Signals and assessment in African elephants: evidence from playback experiments
Animal Behaviour, 1999A series of playback experiments using two elephant vocalizations, the 'musth rumble' and the 'oestrous call', was carried out in Amboseli National Park to examine signalling and assessment in African elephants, Loxodonta africana. In response to the musth rumble of a high-ranking male other musth males approached the speaker aggressively, whereas ...

An intentional vocalization draws others’ attention: A playback experiment with wild chimpanzees
Animal Cognition, 2014A vital step in the evolution of language is likely to have been when signalers explicitly intended to direct recipients' attention to external objects with the use of referential signals. Although animal signals can direct the attention of others to external events, such as in monkey predator alarm calls, there is little evidence that this is the ...

Guinea pig responses to conspecific vocalizations: Playback experiments
Behavioral and Neural Biology, 1981Eight playback experiments are described in which guinea pigs (Cavia porcellus) were individually observed while a tape recording of various guinea pig vocalizations was played. The behavior of subjects was also observed in a silent control test, and in response to nonvocal sounds of varying frequencies.

Conducting Playback Experiments and Interpreting their Results
1992The aim of this chapter is to discuss factors to be considered in the design, execution and interpretation of playback experiments. Most of these factors will be of general concern, even though my examples will be drawn heavily from two-speaker designs with frogs and toads as subjects.

Behavioural effects of persistent human disturbance: a playback experiment in a forest bird
Ecology LettersABSTRACT Increasing human presence and activities expose wild animals to persistent disturbances. Disturbed populations often become tolerant towards humans, although the underlying mechanisms are poorly understood. We used playback experiments to manipulate perceived level of human disturbance in great tits (

Enduring effects of videotape playback experience on family and marital relationships.
American Journal of Orthopsychiatry, 1969The playback of videotape recordings made during a therapy session provides a new therapeutic tool. Participants begin to grasp better the context and complexities of human interactions. Sharing this data with therapists leads patients to a more democratic therapeutic interaction, with implications for more democratic functioning in the families ...

A First Assessment of Birdnet Performance at Varying Distances: A Playback Experiment
Ardeola, 2023Bird vocalisations, like any other acoustic signals, attenuate over distance, and therefore their structure degrades progressively. Such degradation may have an impact on the ability of automated signal recognition software, to detect and correctly identify bird vocalisations.

How vervet monkeys perceive their grunts: Field playback experiments
Animal Behaviour, 1982Abstract Free-ranging vervet monkeys grunt to each other in a variety of social situations: when approaching a dominant or subordinate individual, when moving into a new area of their range, or when observing another group. Like other non-human primate vocalizations, these grunts have traditionally been interpreted as a single, highly variable call ...
