“…In other words, the better their performance, the more food they would receive right away. By providing a "jackpot" of unused food directly following training, we may have unintentionally reinforced poor performance in prior experiments (e.g., McGuire et al, 2017a).…”

“…Although cognitive bias paradigms have been presented to a variety of species ranging from honeybees (Anderson, Hardcastle, Munafò, & Robinson., 2012) to monkeys (Bethell et al, 2012;Pomerantz, Terkel, Suomi, & Paukner, 2012), only a handful of studies have investigated cognitive bias in apes; in chimpanzees (Allritz, Call, & Borkenau, 2016;Bateson & Nettle, 2015) and our own previous work with gorillas (McGuire, Vonk, Fuller, & Allard, 2017a;McGuire, Vonk, & Johnson-Ulrich, 2017b). We were interested in assessing emotional states in a group of bachelor silverback gorillas because they comprise a relatively young group of silverback gorillas that spend a fair bit of time engaging in agonistic behavior, as they attempt to shift or reaffirm their position in the dominance hierarchy.…”

“…We chose to adopt a methodology similar to that used by Keen et al (2014) because it seemed relatively easy to implement given that the gorillas had already participated in, but failed to adequately learn, an ambiguous cue paradigm presented on the computer touchscreen (McGuire et al 2017a;2017b). They had also previously demonstrated their ability to estimate quantities , making it feasible to use differing amounts of food reward as a means to assess optimism.…”

Animal Behavior and Cognition, 5(1) Abstract -In order to assess mood state in three male western lowland gorillas housed in a bachelor group, we developed a novel version of a cognitive bias task. The background color of a touchscreen presented a conditional 'if, then…" rule relating to outcomes involving differential amounts of food rewards. The gorillas struggled to reach a criterion of 80% responding required for testing. In follow-up experiments, we assessed whether the gorillas did in fact prefer three pieces of food to one piece of food when presented with images of food quantities and actual food quantities. Gorillas did not learn to select the stimulus that indicated three food items over one food item when we used images of actual quantities of the rewarded food but they did prefer three actual pieces of food. Thus, like other primates, gorillas may respond differently to quantities of edible and inedible items. In addition, they may struggle with learning conditional discriminations when cues to differential responses and outcomes are arbitrary rather than intuitively connected. These studies highlight the importance of methodology when devising tests to assess cognition or affect in nonhuman primates.

We have an ethical responsibility to provide captive animals with environments that allow them to experience good welfare. Husbandry activities are often scheduled for the convenience of care staff working within the constraints of the facility, rather than considering the biological and psychological requirements of the animals themselves. The animal welfare 24/7 across the lifespan concept provides a holistic framework to map features of the animal's life cycle, taking into account their natural history, in relation to variations in the captive environment, across day and night, weekdays, weekends, and seasons. In order for animals to have the opportunity to thrive, we argue the need to consider their lifetime experience, integrated into the environments we provide, and with their perspective in mind. Here, we propose a welfare assessment tool based upon 14 criteria, to allow care staff to determine if their animals' welfare needs are met. We conclude that animal habitat management will be enhanced with the use of integrated technologies that provide the animals with more opportunities to engineer their own environments, providing them with complexity, choice and control.

“…Instead, nonsystematic methods and subjective measures are typical, if an assessment is conducted at all. This approach leaves some question as to the effectiveness of various enrichment programs (Broom, 1988;Canali & Keeling, 2009;Clegg & Delfour, 2018;Delfour & Beyer, 2012;Hoy et al, 2010;Makecha & Highfill, 2018;Newberry, 1995), which range from simply adding objects to an enclosure to social housing (Daoudi et al, 2017;Yeater et al, 2013), training (Ramirez, 1999;Westlund, 2014), introducing scent (Nelson Slater & Hauber, 2017;Samuelson et al, 2016), or supplying more naturalistic or challenging feeding opportunities (Fernandez & Timberlake, 2019;McPhee, 2002;Wagman et al, 2018) to name a few. There is evidence that some enrichment programs may even result in an increase in unwanted behaviors, such as increased aggression (Franks et al, 2009), manipulation of the enrichment to the point in which it becomes dangerous for the animals (Hahn et al, 2000;Hare et al, 2007), or other undesirable behaviors (Bloomsmith et al, 1991).…”

Is Enrichment Always Enriching and How Would You Know? Unintended Consequences and the Importance of Formal Assessment of Enrichment Programs in Bottlenose Dolphins (Tursiops truncatus)

Bottlenose dolphins (Tursiops truncatus) are viewed as a highly intelligent species, capable of complex behaviors, requiring marine parks to maintain dynamic environmental enrichment procedures in order to ensure their optimal psychological and physiological well-being in human care. In this study, two experiments were conducted to determine the effects of different forms of enrichment on the behavior of bottlenose dolphins. In Experiment 1, the most successful enrichment included highly novel items, which resulted in avoidance, but also what is frequently considered positive behavioral changes including a reduction in circle swimming and an increase in social behavior. In Experiment 2, the use of choice resulted in negative unintended social consequences. These two experiments together demonstrate that the results of deploying enrichment may not be as clear-cut as previously presumed. In order to maintain positive benefits of enrichment, the results of this study suggest that unique forms of enrichment should be implemented on a variable schedule that is offered several times a year and consistently evaluated for effectiveness.
