When making decisions in a cluttered world, humans and other animals often have to hold multiple items in memory at once -- for instance, remembering the different items on a shopping list. Interestingly, psychophysical experiments in humans and other animals have shown that sometimes the remembered stimuli become confused; that is, instead of reporting a stimulus that was actually present, the participant will occasionally report a chimeric stimulus, composed of feature values that were present but bound together in combinations that were not (e.g., setting out to buy a green apple and red pe

In complex environments, individuals need to be able to selectively focus on relevant information and to maintain it for later use. Attention and working memory (WM) represent two core cognitive abilities that are involved in cognitive control. Higher cognitive abilities have mostly been demonstrated in primates, yet corvid songbirds show remarkably similar skills. Therefore, we used jackdaws to study these instances of cognitive control. Two jackdaws were trained on a delayed estimation paradigm, tailored to probe attention and WM processes. One of two simultaneously presented sample colors h
