Implications of breaking mother–young social bonds (2008, background): “Information about the emotional state of the animals is conveyed by the frequency, patterning and intensity of calls emitted during their attempts to reinstate contact, providing a means of assessing each caller’s level of motivation to reunite (Weary et al., 1999; Watts and Stookey, 2000; Knutson e”
On the Embodied Neural Nature of Core Emotional Affects (2005, background): “We can only obtain comparable evidence in other animals by careful studies of their natural emotional and motivated behaviours (Panksepp, 1998a, 2005a), especially their emotional vocalizations that may reflect their internal affective states (Knutson et al., 2002; Panksepp et al., 1988, 2002).”
A spatial judgement task to determine background emotional state in laboratory rats, Rattus norvegicus (2008, methodology): “This result failed to meet our prediction that, because 50kHz USVs appear to indicate a positive emotional state in the vocalizer (e.g. Knutson et al., 2002; Burman et al., 2007), the rats’ anticipation of a reward would be reflected in both the time taken for them to reach the probe location and…”
Cross-cultural recognition of basic emotions through nonverbal emotional vocalizations (2010, neutral): “Tickling triggers laugh-like vocalizations in nonhuman primates (25) as well as other mammals (26), suggesting that it is a social behavior with deep evolutionary roots (27).”
Vocal Expression of Emotions in Mammals: Mechanisms of Production and Evidence (2012, background): “There is substantial evidence from ethological, pharmacological, and brain stimulation studies that these two types of calls reflect the emotional valence of the caller, either negative (22 kHz alarm calls) or positive (50 kHz social calls, e.g. Knutson et al., 2002; Burgdorf & Moskal, 2009).”
The neurobiology of positive emotions. (2006, background): “…are organized similarly in the brains of all mammals, and it has been argued that we cannot make sense of such behavioral changes unless we begin to take affective experiences more seriously in the lives of other animals (Knutson et al., 2002; Panksepp et al., 2002; Panksepp et al., 2005).”
Affective consciousness: Core emotional feelings in animals and humans. (2005, background): “…''self-reports'') in environments where they have received drugs that are hedonically positive to humans, and negative vocalizations (22 kHz ''complaints'') when placed in locations where they have received aversive drugs (Burgdorf, Knutson, Panksepp, & Ikemoto, 2001a, 2001b; Knutson et al., 2002).”
Measuring emotional processes in animals: the utility of a cognitive approach. (2005, neutral): “It is also worth pointing out that, apart from some notable exceptions [52,53], the majority of research into emotion measurement in animals has focused on negative states, particularly fear, anxiety, and ‘stress’.”
What is it like to be a rat? Rat sensory perception and its implications for experimental design and rat welfare (2008, background): “The second ultrasonic vocalisation is the ‘22 kHz long-call’, which occurs mainly in aversive situations and might therefore indicate negative affect (Knutson et al., 2002).”
