Breaking conversational rules matters to captive gorillas: A playback experiment. [PDF]
Sci Rep, 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.

Aversive behavioural responses of killer whales to sounds of long-finned pilot whales [PDF]
Scientific ReportsInteractions are common among marine species which use sound as the primary form of communication, yet the role of acoustic signals in mediating these interactions remains poorly understood.

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.

Synchronising video playback information within a distributed framework [PDF]
, 2013 This paper details a mechanism to distribute time coded objects to devices in order to synchronise and control video playback within a web environment. We comment on a three-tier architecture of server, client and second screen and the implementation of ...

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
