Chickens Play To The Crowd, Cinzia Chiandetti
Animal Sentience
The time was ripe for Marino’s review of chickens’ cognitive capacities. The research community, apart from expressing gratitude for Marino’s work, should now use it to increase public awareness of chickens’ abilities. People’s views on many animals are ill-informed. Scientists need to communicate and engage with the public about the relevance and societal implications of their findings.
Displaying Jealous Behavior Versus Experiencing Jealousy,

Displaying Jealous Behavior Versus Experiencing Jealousy, Judit Abdai, Ádám Miklósi
Animal Sentience
Jealous behavior is the manifestation of complex behavioral interactions initiated by an individual who aims to maintain an important social relationship that is threatened by a rival. Researchers prefer to focus on the emotion thought to control this behavior, “jealousy,” before understanding the mechanisms of the behavior. Researchers conducting recent behavioral studies on jealous behavior in dogs are still struggling to find strong experimental evidence. Thus, the positive correlation between amygdala activation and reported aggression in dogs described in Cook et al.’s target article is far from constituting evidence for “jealousy” in dogs.

Sentience In Fishes: More On The Evidence, Michael L. Woodruff
Animal Sentience
In my target article, I argued that the brains of ray-finned fishes of the teleost subclass (Actinopterygii) are sufficiently complex to support sentience — that these fishes have subjective awareness of interoceptive and exteroceptive sense experience. Extending previous theories centered on the tectum, I focused on the organization of the fish pallium. In this Response to the commentaries, I clarify that I do not propose that the fish pallium is, or must be, homologous to the mammalian neocortex to play a role in sentience. Some form of a functionalist approach to explaining the neural basis of sentience across taxa is …

Social Relationships And Self-Directed Behavior In Hamadryas Baboons (Papio Hamadryas Hamadryas), Melissa C. Painter
Master’s Theses
Self-directed behavior, such as self-scratching and self-grooming, is a behavioral indicator of anxiety in nonhuman primates. Patterns of self-directed behavior are used to identify social and environmental factors related to primate anxiety. This study explored the social context in which individuals in a captive group of hamadryas baboons (Papio hamadryas hamadryas) exhibited self-directed behavior. Self-directed behavior in a partner’s presence was predicted to increase with relationship insecurity. More than 130 hours of behavioral observations were conducted on 12 baboons. Self-directed and social behavior were recorded with focal sampling to determine each animal’s self-directed behavior rate in the presence …
Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?,

Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?, Danielle M. Andrews
Theses and Dissertations--Psychology
The principle of least effort suggests that animals should minimize effort to reinforcement. Thus, not pecking should be preferred over pecking. However, pigeons often peck when it is allowed but not required (e.g., fixed time schedules) but pecking may be adventitiously reinforced. In the present experiment, to better compare a schedule of reinforcement that requires pecking with one that requires the absence of pecking, we compared a fixed-interval (FI) schedule in which reinforcement follows the first peck after the interval has elapsed and a differential-reinforcement-of-other behavior (DRO) schedule which requires pigeons abstain from pecking for a similar interval. The delay …
Does Observational Learning Influence Spatial Pattern Learning?,

Does Observational Learning Influence Spatial Pattern Learning?, Matthew Bruster
Electronic Theses and Dissertations
Previous studies have indicated both human and non-human animals come under control of a hidden spatial pattern when engaged in an open field search task, and rats appear to exhibit social learning in such tasks through the influence of a conspecific on their search behavior. Although human participants appear to perform similarly in both real-world and virtual environment versions of a spatial pattern search task, evidence from human participants for social learning in such a task remains lacking. The current experiments tested the influence of social learning (observational learning) on human performance in a spatial pattern learning task within a …

The Imprint Of Childhood Abuse On Trauma-Related Shame In Adulthood, Joan A. Reid
Dignity: A Journal of Analysis of Exploitation and Violence
Research has consistently linked residual trauma-related shame among child sexual abuse (CSA) survivors to sexual revictimization, health risk behaviors, and poorer response to mental health treatment. However, questions remain regarding the imprint of childhood maltreatment on trauma-related shame including which CSA characteristics or types of childhood maltreatment contribute to residual shame in adulthood. Using data drawn from a prospective study of 174 primarily African American women with histories of CSA and a matched comparison group, this study explores whether specific characteristics of CSA (familial CSA, CSA with penetration, force used by CSA perpetrator), repeat sexual victimization in adolescence, childhood physical …

Cultural Consultations In Criminal Forensic Psychology: A Thematic Analysis Of The Literature, Alesya Radosteva
Antioch University Full-Text Dissertations & Theses
The importance of culture as a reference point in clinical practices such as forensic psychology has been considerably valued yet poorly understood, especially in an age where precision and sophistication outlast cultural authenticity and patient-clinician relationship. This paper looks at the gaps and inconsistencies that exist in current forensic psychology research. The topic is introduced by delving into the understanding of the phenomenon of culture and its influences on our everyday conditioning. Aspects such as language, biological development, traditions, rituals, and narratives are emphasized as potent tools that drive individuals to create and mold culture according to needs and requirements …

Behavioral Indicators Of Poor Welfare In Shelter Dogs, Paige M. Adams, Suma Mallavarapu
The Kennesaw Journal of Undergraduate Research
We studied behavioral indicators of poor welfare in shelter dogs. Our research question was: How is the welfare of shelter dogs affected by length of stay at a shelter, age, sex, and breed. Data were collected on 18 dogs from October 2016 to March 2017 at a small private shelter in Marietta, GA. Data were collected in 15-minute sessions when the dogs were in their indoor enclosures. No significant differences were found in time spent in abnormal behaviors among dogs that were at the shelter for less than 1 month, 1-6 months, and longer than 6 months, between males and …

Signature Whistle Production During A Bottlenose Dolphin Group Integration, Megan S. Broadway
Dissertations
Bottlenose dolphins are an important species of interest because they possess a variety of abilities that are relatively rare in the animal kingdom, one being complex acoustic communication. Signature whistles - distinctive calls that are unique for each individual – are one of the most studied call types, but we know little about how these calls are used in various contexts, such as during an introduction. Looking at the socio-behavioral context in which signature whistles are used is likely the best way of learning how these whistles are used in a particular context (Caldwell, Caldwell, & Tyack, 1990). For this …

Evaluating Social Network Dynamics Of Bigg’S Killer Whales (Orcinus Orca) And Vessel Traffic Within A Transboundary Region: Implications For Conservation Management, Courtney Smith
Dissertations
The social lives of animals are defined by group dynamics based on the nature and strength of associations and movements between individuals, often resulting in highly complex and interconnected social networks. However, understanding of how environmental variables may shape this structure is poorly understood. Within the inland waters of Washington State and southern Vancouver Island, British Columbia, mammal-eating Bigg’s (transient) killer whales occur in relatively small, but stable social groups. Group size and occurrence in recent years has increased, coinciding with a growing whale watching industry. Given the central importance of the social network within killer whale population dynamics, such …

The Mental Homologies Of Mammals. Towards An Understanding Of Another Mammalsworld View, Marthe Kiley-Worthington
Theory of Mind Collection
Mammals’ mental homologies include that they look after their young, suckle and protect them; they acquire information about the world by learning. They have five types of sensory receptors and a brain to analyze the information and they feel: that is they are sentient. Mental homologies have been largely ignored by behavioural scientists since Darwin because of certain historical beliefs. This however has not been the case for people who have had to do with non-human mammals who have long recognized their mental similarities to humans. As a result, behavioural science has sponsored some inappropriate research (examples are given). The …

Goats Display Audience-Dependent Human-Directed Gazing Behaviour In A Problem-Solving Task, Christian Nawroth, Jemma M. Brett, Alan G. Mcelligott
Alan G. McElligott, Ph.D.
Domestication is an important factor driving changes in animal cognition and behaviour. In particular, the capacity of dogs to communicate in a referential and intentional way with humans is considered a key outcome of how domestication as a companion animal shaped the canid brain. However, the lack of comparison with other domestic animals makes general conclusions about how domestication has affected these important cognitive features difficult. We investigated human-directed behaviour in an ‘unsolvable problem’ task in a domestic, but non-companion species: goats. During the test, goats experienced a forward-facing or an away-facing person. They gazed towards the forward-facing person earlier …

The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott
Alan G. McElligott, PhD
The development of accurate measures of animal emotions is important for improving and promoting animal welfare. Cognitive bias indicates the effect of emotional states on cognitive processes, such as memory, attention, and judgement. Cognitive bias tests complement existing behavioural and physiological measures for assessing the valence of animal emotions indirectly. The judgement bias test has been used to assess emotional states in non-human animals; mainly in laboratory settings. The aim of this review is to summarise the findings on the use of the judgement bias test approach in assessing emotions in non-human animals, focusing in particular on farm livestock. The …

Vocal plasticity is the ability of an individual to modify its vocalizations according to its environment. Humans benefit from an extreme form of vocal plasticity, allowing us to produce a wide range of sounds. This capacity to modify sounds has been shown in three bird orders and in a few nonhuman mammal species, all characterized by complex vocal communication systems. In other mammals, there is no evidence for a social impact on vocal development. We investigated whether contact calls were affected by social environment and kinship during early ontogeny in goats, a highly vocal and social species. To test the …

Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott
Alan G. McElligott, PhD
Moods influence cognitive processes in that people in positive moods expect more positive events to occur and less negative ones (“optimistic bias”), whereas the opposite happens for people in negative moods (“pessimistic bias”). The evidence for an effect of mood on cognitive bias is also increasing in animals, suggesting that measures of optimism and pessimism could provide useful indicators of animal welfare. For obvious ethical reasons, serious poor treatments cannot be easily replicated in large mammals in order to study their long-term effects on moods. In this study, we tested the long-term effects (>2 years) of prior poor welfare …
Mutual Mother–Offspring Vocal Recognition In An Ungulate Hider Species (Capra Hircus),

Mutual Mother–Offspring Vocal Recognition In An Ungulate Hider Species (Capra Hircus), Elodie F. Briefer, Alan G. Mcelligott
Alan G. McElligott, PhD
Parent–offspring recognition can be essential for offspring survival and important to avoid misdirected parental care when progeny mingle in large social groups. In ungulates, offspring anti-predator strategies (hiding vs. following) result in differences in mother–offspring interactions, and thus different selection pressures acting on the recognition process during the first weeks of life. Hider offspring are isolated and relatively stationary and silent to avoid detection by predators, whereas follower offspring are mobile and rapidly mix in large social groups. For these reasons, hiders have been suggested to show low offspring call individuality leading to unidirectional recognition of mothers by offspring and …

Judgement Bias In Goats (Capra Hircus): Investigating The Effects Of Human Grooming, Luigi Baciadonna, Christian Nawroth, Alan G. Mcelligott
Alan G. McElligott, PhD
Animal emotional states can be investigated by evaluating their impact on cognitive processes. In this study, we used a judgement bias paradigm to determine if shortterm positive human-animal interaction (grooming) induced a positive affective state in goats. We tested two groups of goats and trained them to discriminate between a rewarded and a non-rewarded location over nine training days. During training, the experimental group (nD9) was gently groomed by brushing their heads and backs for five min over 11 days (nine training days, plus two testing days, total time 55 min). During training, the control group (nD10) did not experience …

Mother Goats Do Not Forget Their Kids’ Calls, Elodie F. Briefer, Mónica Padilla De La Torre, Alan G. Mcelligott
Alan G. McElligott, PhD
Parent–offspring recognition is crucial for offspring survival. At long distances, this recognition is mainly based on vocalizations. Because of maturation-related changes to the structure of vocalizations, parents have to learn successive call versions produced by their offspring throughout ontogeny in order to maintain recognition. However, because of the difficulties involved in following the same individuals over years, it is not clear how long this vocal memory persists. Here, we investigated long-term vocal recognition in goats. We tested responses of mothers to their kids’ calls 7–13 months after weaning. We then compared mothers’ responses to calls of their previous kids with …
Intrasexual Selection Drives Sensitivity To Pitch, Formants And Duration In The Competitive Calls Of Fallow Bucks,

Intrasexual Selection Drives Sensitivity To Pitch, Formants And Duration In The Competitive Calls Of Fallow Bucks, Benjamin J. Pitcher, Elodie Briefer, Alan G. Mcelligott
Alan G. McElligott, PhD
Background: Mammal vocal parameters such as fundamental frequency (or pitch; fo) and formant dispersion often provide information about quality traits of the producer (e.g. dominance and body size), suggesting that they are sexually selected. However, little experimental evidence exists demonstrating the importance of these cues in intrasexual competition, particularly fo. Male Fallow deer (bucks) produce an extremely low pitched groan. Bucks have a descended larynx and generate fo well below what is expected for animals of their size. Groan parameters are linked to caller dominance, body size and condition, suggesting that groans are the product of sexual selection. Using a …
