Dogs showing separation-related behaviour exhibit a ‘pessimistic’ cognitive bias
but rice will not make as effective use of the additional CO2 as would other C3 crops — those plants that, like 55% of grass species, have the basic mechanism of photosynthetic CO2 assimilation. An alternative is to change rice into a C4 plant, which could increase yield by up to 50% while using little or no more nitrogen or water. Although the challenges to such a venture are many and large, t...
متن کاملDogs with separation-related problems show a “less pessimistic” cognitive bias during treatment with fluoxetine (Reconcile™) and a behaviour modification plan
BACKGROUND Canine separation-related problems (SRP) (also described as "separation anxiety" or "separation distress") are among the most common behavioural complaints of dog owners. Treatment with psychoactive medication in parallel with a behaviour modification plan is well documented in the literature, but it is unknown if this is associated with an improvement in underlying affective state (...
متن کاملAgitated Honeybees Exhibit Pessimistic Cognitive Biases
Whether animals experience human-like emotions is controversial and of immense societal concern [1-3]. Because animals cannot provide subjective reports of how they feel, emotional state can only be inferred using physiological, cognitive, and behavioral measures [4-8]. In humans, negative feelings are reliably correlated with pessimistic cognitive biases, defined as the increased expectation o...
متن کاملA comparison between wolves, Canis lupus, and dogs, Canis familiaris, in showing behaviour towards humans
Both human and nonhuman primates use imperative pointing to request a desired object from another individual. Gaze alternation often accompanies such pointing gestures, and in species that have no hands this can in itself function as imperative pointing. Dogs have exceptional skills in communicating with humans. The early development of these skills is suggested to have been facilitated by dome...
متن کاملShift-Pessimistic Active Learning Using Robust Bias-Aware Prediction
Existing approaches to active learning are generally optimistic about their certainty with respect to data shift between labeled and unlabeled data. They assume that unknown datapoint labels follow the inductive biases of the active learner. As a result, the most useful datapoint labels—ones that refute current inductive biases— are rarely solicited. We propose a shift-pessimistic approach to a...
