Emotion is defined as any mental experience with high intensity and high hedonic content. The existence and nature of emotions in non-human animals are believed to be correlated with those of humans and to have evolved from the same mechanisms. Charles Darwin was one of the first scientists to write about the subject, and his observational (and sometimes anecdotal) approach has since developed into a more robust, hypothesis-driven, scientific approach. Cognitive bias tests and learned helplessness models have shown feelings of optimism and pessimism in a wide range of species, including rats, dogs, cats, rhesus macaques, sheep, chicks, starlings, pigs, and honeybees. Jaak Panksepp played a…

Diagnostic performance of lung ultrasound compared to thoracic radiography in non-traumatized dogs and cats with respiratory distress in an emergency setting.. Introduction Respiratory distress is a medical emergency requiring rapid diagnostic decision-making. This prospective observational study evaluated the efficiency and diagnostic performance of lung ultrasound (LUS) and thoracic radiography (TXR) in dogs and cats presenting with tachypnea. Imaging-based suspected diagnoses were compared with definitive diagnoses established by specialists using additional diagnostic procedures. The influence of observer experience on diagnostic accuracy was assessed. Methods Client-owned animals with…

Semantic congruence impacts audiovisual processing in the Colavita effect.. The Colavita effect is a phenomenon that occurs when participants are presented with auditory, visual, and audiovisual stimuli and are tasked to identify the modality of the stimuli. When audiovisual stimuli are presented, participants occasionally miss the auditory component and report that the stimulus was visual only - reflecting visual dominance. The Colavita effect has been shown to be resistant to manipulations of semantic correspondence, which is surprising considering that semantic information impacts multiple perceptual tasks. It is possible that the brief auditory stimuli used for Colavita tasks do not all…
