Breaking conversational rules matters to captive gorillas: A playback experiment [PDF]
Scientific Reports, 2020 AbstractAcross human cultures, conversations are regulated by temporal and social rules. The universality of conversational rules suggests possible biological bases and encourages comparisons with the communicative interactions of nonhuman animals. Unexpectedly, few studies have focused on other great apes despite evidence of proto-conversational rules

Bioacoustic Field Research: A Primer to Acoustic Analyses and Playback Experiments With Primates [PDF]
American Journal of Primatology, 2013 AbstractAcoustic analyses of primate vocalizations as well as playback experiments are staple methods in primatology. Acoustic analyses have been used to investigate the influence of factors such as individuality, context, sex, age, and size on variation in calls.

Context‐Dependent Reactive Antipredator Behavior of Chacma Baboons (Papio ursinus griseipes) Amidst Predator Recovery [PDF]
American Journal of Primatology, Volume 88, Issue 10, October 2026.Chacma baboons exhibited context‐dependent flight and vigilance behavior in response to experimental predator vocalizations in Mozambique's Gorongosa National Park. Reactions were strongest in juveniles and in individuals with fewer otherbaboons in frame and in response to leopard and wild dog cues, and weakened with increased exposure to predators ...

Variations in advertisement call modulations do not influence vocal interactions in bullfrog choruses [PDF]
JASA Express Letters, 2022 Chorusing male bullfrogs naturally vary the number of modulations within their advertisement call notes. A field playback experiment investigated whether these variations affect males' evoked vocal responses.

Brain Sciences, 2021 We investigated the effects of prior stress on rats’ responses to 50-kHz (appetitive) and 22-kHz (aversive) ultrasonic playback. Rats were treated with 0, 1, 6 or 10 shocks (1 s, 1.0 mA each) and were exposed to playbacks the following day.

Pupil size changes reveal dogs’ sensitivity to motion cues
iScience, 2022 Summary: Certain motion cues like self-propulsion and speed changes allow human and nonhuman animals to quickly detect animate beings. In the current eye-tracking study, we examined whether dogs’ (Canis familiaris) pupil size was influenced by such ...

A Study on the Development of Playback Control Software for Mark5B VSI System [PDF]
Journal of Astronomy and Space Sciences, 2010 We developed the playback control software for a high-speed playback system which is a component of the Korea-Japan Joint VLBI Correlator (KJJVC). The Mark5B system, which is a recorder and playback system used in the Korean VLBI Network (KVN), has two
