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

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.

Acoustic Features and Recognition of Distress Calls in Rhinolophus nippon: A Study Combining Machine Learning and Playback Experiments [PDF]
BiologyVocal signals are the primary medium of intraspecific communication in bats, yet the encoding features and recognition mechanisms of distress calls remain largely unclear.

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.

Transmission of Urgency Levels in the Alarm Calls of the Oriental Reed Warbler [PDF]
Ecology and EvolutionMany animals communicate predator‐related information to conspecifics through alarm calls that exhibit acoustic structural variations encoding key parameters such as predator type, body size, and urgency of danger.

Female Cuckoo Calls Are More Effective at Attracting Breeding Male Cuckoos and Their Hosts Than Male Cuckoo Calls [PDF]
Ecology and EvolutionVocalizations during the breeding season play a significant role in both intra‐ and inter‐specific communications. There have been numerous studies on the calls and functions of the common cuckoo (Cuculus canorus [CC]). However, there is limited research

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.

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 ...
