Cognitive bias as an indicator of animal emotion and welfare: Emerging evidence and underlying mechanisms
TLDR
This paper found that animals in a negative affective state are more likely to respond to ambiguous cues as if they predict the negative event (a "pessimistic" response), than animals in more positive states.About:

An integrative and functional framework for the study of animal emotion and mood
TL;DR: D discrete and dimensional approaches are brought together to offer a structure for integrating different discrete emotions that provides a functional perspective on the adaptive value of emotional states, and suggest how long-term mood states arise from short-term discrete emotions.

Animal play and animal welfare
Suzanne D E Held,Marek Špinka +1 more
TL;DR: In this paper, the authors review evidence on four aspects of the play-welfare relationship: play indicates the absence of fitness threats, play acts as a reward and flags up the presence of opioid-mediated pleasurable emotional experiences; play brings immediate psychological benefits and long-term fitness and health benefits, and thus improves current and future welfare; and play is socially contagious and therefore capable of spreading good welfare in groups.

Agitated Honeybees Exhibit Pessimistic Cognitive Biases
TL;DR: This work asks whether honeybees display a pessimistic cognitive bias when they are subjected to an anxiety-like state induced by vigorous shaking designed to simulate a predatory attack and shows that the bees' response to a negatively valenced event has more in common with that of vertebrates than previously thought.
Journal ArticleDOI
Defining and assessing animal pain
TL;DR: Criteria that demonstrate, beyond a reasonable doubt, whether animals of a given species experience pain are defined that are vital to inform whether to alleviate pain or to drive the refinement of procedures to reduce invasiveness.

Prospect theory: an analysis of decision under risk
Daniel Kahneman,Amos Tversky +1 more
TL;DR: In this paper, the authors present a critique of expected utility theory as a descriptive model of decision making under risk, and develop an alternative model, called prospect theory, in which value is assigned to gains and losses rather than to final assets and in which probabilities are replaced by decision weights.

Development and validation of brief measures of positive and negative affect: The PANAS scales.
TL;DR: Two 10-item mood scales that comprise the Positive and Negative Affect Schedule (PANAS) are developed and are shown to be highly internally consistent, largely uncorrelated, and stable at appropriate levels over a 2-month time period.

A Neural Substrate of Prediction and Reward
TL;DR: Findings in this work indicate that dopaminergic neurons in the primate whose fluctuating output apparently signals changes or errors in the predictions of future salient and rewarding events can be understood through quantitative theories of adaptive optimizing control.

Risk, Ambiguity, and the Savage Axioms
TL;DR: The notion of "degrees of belief" was introduced by Knight as mentioned in this paper, who argued that people tend to behave "as though" they assigned numerical probabilities to events, or degrees of belief to the events impinging on their actions.
