Perception of vocoded speech in domestic dogs
Anim Cogn. 2024 Apr 16;27(1):34. doi: 10.1007/s10071-024-01869-3.ABSTRACTHumans have an impressive ability to comprehend signal-degraded speech; however, the extent to which comprehension of degraded speech relies on human-specific features of speech perception vs. more general cognitive processes is unknown. Since dogs live alongside humans and regularly hear speech, they can be used as a model to differentiate between these possibilities. One often-studied type of degraded speech is noise-vocoded speech (sometimes thought of as cochlear-implant-simulation speech). Noise-vocoded speech is made by dividing the speech signa...

Figure-ground segmentation based on motion in the archerfish
Anim Cogn. 2024 Apr 15;27(1):33. doi: 10.1007/s10071-024-01873-7.ABSTRACTFigure-ground segmentation is a fundamental process in visual perception that involves separating visual stimuli into distinct meaningful objects and their surrounding context, thus allowing the brain to interpret and understand complex visual scenes. Mammals exhibit varying figure-ground segmentation capabilities, ranging from primates that can perform well on figure-ground segmentation tasks to rodents that perform poorly. To explore figure-ground segmentation capabilities in teleost fish, we studied how the archerfish, an expert visual hunter, perf...

How to solve novel problems: the role of associative learning in problem-solving performance in wild great tits Parus major
Anim Cogn. 2024 Apr 12;27(1):32. doi: 10.1007/s10071-024-01872-8.ABSTRACTAlthough problem-solving tasks are frequently used to assess innovative ability, the extent to which problem-solving performance reflects variation in cognitive skills has been rarely formally investigated. Using wild breeding great tits facing a new non-food motivated problem-solving task, we investigated the role of associative learning in finding the solution, compared to multiple other non-cognitive factors. We first examined the role of accuracy (the proportion of contacts made with the opening part of a string-pulling task), neophobia, explorati...

Social demonstration of colour preference improves the learning of associated demonstrated actions
Anim Cogn. 2024 Apr 9;27(1):31. doi: 10.1007/s10071-024-01865-7.ABSTRACTWe studied how different types of social demonstration improve house sparrows' (Passer domesticus) success in solving a foraging task that requires both operant learning (opening covers) and discrimination learning (preferring covers of the rewarding colour). We provided learners with either paired demonstration (of both cover opening and colour preference), action-only demonstration (of opening white covers only), or no demonstration (a companion bird eating without covers). We found that sparrows failed to learn the two tasks with no demonstration, a...

A preliminary analysis of the effect of individual differences on cognitive performance in young companion dogs
In this study, companion dogs under 12 months of age were tested once on two tasks purported to measure aspects of executive function: the delayed-search task (DST) and the detour reversal task (DRT). Owners also filled out the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) to evaluate how temperament influenced task performance. Contrary to prior research, performance did not improve with age on either task. However, the lack of age effects was likely the result of small sample sizes and individual differences across other factors influencing performance. Specifically, temperament differences as measured...

No evidence tube entrapment distresses rodents in typical empathy tests
Anim Cogn. 2024 Apr 1;27(1):29. doi: 10.1007/s10071-024-01863-9.ABSTRACTIn the first two experiments an empty tube open at one end was placed in different locations. Male hamsters, tested one at a time, tended to stay close to the tube or in it. During the first minute of the first 4 sessions of Experiment 3, the hamster was unrestrained. If it entered the tube, it was locked within the tube. If it did not enter the tube during the first min, it was placed in it, and the tube was locked. Fifteen min later, the tube was opened, and the hamster was unrestrained for a further 20 min. The tube remained open during Session 5. H...
