Emotion, Pain, & Sentience

The psychology of cows

Domestic cows (Bos taurus) are consumed worldwide as beef and veal, kept as dairy product producers, employed as draft animals in labor, and are used for a long list of other products, including leather and manure. But despite global reliance...

Positive affect and learning: Exploring the “Eureka Effect” in dogs

Animals may experience positive affective states in response to their own achievements. We investigated emotional responses to problem-solving in dogs, separating these from reactions to rewards per se using a yoked control design. We also questioned whether the intensity of...

The psychology of cows? A case of over-interpretation and personification

Reviews of existing literature on topics that have been neglected, such as the subject of the cognitive and affective abilities of cows, are productive and necessary exercises in science (Elwen, Findlay, Kiszka, & Weir, 2011; Mulrow, 1994). These syntheses organize...

Investigating emotional contagion in dogs (Canis familiaris) to emotional sounds of humans and conspecifics

Emotional contagion, a basic component of empathy defined as emotional state-matching between individuals, has previously been shown in dogs even upon solely hearing negative emotional sounds of humans or conspecifics. The current investigation further sheds light on this phenomenon by...

Social transmission of Pavlovian fear: Fear-conditioning by-proxy in related female rats

Pairing a previously neutral conditioned stimulus (CS; e.g., a tone) to an aversive unconditioned stimulus (US; e.g., a foot-shock) leads to associative learning such that the tone alone will elicit a conditioned response (e.g., freezing). Individuals can also acquire fear...

Why it hurts: With freedom comes the biological need for pain

We argue that pain is not needed to protect the body from damage unless the organism is able to make free choices in action selection. Then pain (including its affective and evaluative aspects) provides a necessary prioritising motivation to select...

Emotional contagion of distress in young pigs is potentiated by previous exposure to the same stressor

This study tested whether emotional contagion occurs when piglets directly observe a penmate in distress (restraint) and whether there is an effect of previous experience on the response to subsequent restraint or exposure to conspecific distress. Piglets (49.7 ± 0.7...

Caution is required when considering sentience in animals: A response to the commentary by Briffa (2022) on “Hermit crabs, shells, and sentience” (Elwood 2022)

My recent review examined the complex and intimate relationship between hermit crabs and the empty gastropod shells upon which they depend for survival. Because shells come with costs as well as benefits, the crabs are highly selective about which ones...

Hermit crabs, shells, and sentience

Hermit crabs have an intimate relationship with gastropod shells and show numerous activities by which they locate, select, and change shells in different contexts. They gather information about new shells and update information about their existing shells. This involves integration...

Behavioural indicators of pain and suffering in arthropods and might pain bite back?

Pain in response to tissue damage functions to change behaviour so that further damage is minimised whereas healing and survival are promoted. This paper focuses on the behavioural criteria that match the function to ask if pain is likely in...
