Color vision is an important perceptual ability in most species and a crucial capacity underlying any cognitive task working with color stimuli. Birds are known for their outstanding tetrachromacy. Two jackdaws were trained to indicate whether they perceive two colors as same or different. The dominant wavelengths of the experimental assessed relate birds' performance physical qualities results that differences similarities had strong influence on behavioral data. Colors related reduced...
Categorization represents one cognitive ability fundamental to animal behavior. Grouping of elements based on perceptual or semantic features helps reduce processing resources and facilitates appropriate Corvids master complex categorization, yet the detailed categorization learning strategies are less well understood. We trained two jackdaws a delayed match category paradigm using novel, artificial stimulus type, RUBubbles. Both birds learned differentiate between session-unique categories...
Working memory (WM) is a crucial element of the higher cognition primates and corvid songbirds. Despite its importance, WM has severely limited capacity vulnerable to noise. In primates, attractor dynamics mitigate effect noise by discretizing continuous information. Yet, it remains unclear whether similar are seen in avian brains. Here, we show jackdaws (Corvus monedula) have behavioral biases as humans; memories less precise more biased demands increase. Model-based analysis reveal...
Grouping objects into discrete categories affects how we perceive the world and represents a crucial element of cognition. Categorization is widespread phenomenon that has been thoroughly studied. However, investigating categorization learning poses several requirements on stimulus set in order to control which feature used prevent mere stimulus-response associations or rote learning. Previous studies have wide variety both naturalistic artificial categories, latter having advantages such as...
