“…Actually, it is a moot point whether "distress" calls reflect fear, anxiety, general stress, or whatever negative emotional or motivational state. It is a widely accepted conclusion (Bermant, 1963;Collias & Collias, 1956;Collias & Joos, 1953;Guyomarc'h, 1962;Hess & Schaefer, 1959;Hoffman, 1968;Rajecki, Eichenbaum, & Heilweil, 1973;Salzen & Tomlin, 1963) that these calls reflect some relatively unpleasant state. The existence of any strong, unpleasant psychological reaction seems incompatible with exploratory tendencies, but less incompatible with aggressive reactions.…”

Free interaction between domestic chicks involved intersubject pecking. During tests as early as 1 day after hatching, socially reared birds showed reliable social discriminations by pecking more at strangers than they pecked at their cage mates. Compared with socially reared birds, chicks reared in isolation exhibited certain exaggerated or atypical response patterns. These patterns included heightened rates of intersubject peeking, a pronounced tendency to peck at the head, elevated emotionality as reflected in the distress call, and the failure of pair-mates to show matched rates of environmental pecking. Inferences were drawn from these patterns, with the conclusion that infantile intersubject pecking in chicks may be based on aggressive rather than strictly exploratory tendencies. The findings were discussed in terms of the development of a basic tolerance for conspecifics and early social orderings.

“…It has been suggested that “[m]ost mammalian young cry when separated from their mothers and homes” (Carden, Barr, & Hofer, 1991, p. 17). Investigators have documented separation calls from a variety of animal young, including ducks (Gaioni, DePaulo, & Hoffman, 1980), chickens (Rajecki, Eichenbaum, & Heilweil, 1973), guinea pigs (Pettijohn, 1979), dogs (Gurski, Davis, & Scott, 1980), and human (Michelsson, Christensson, Rothgänger, & Winberg, 1996) and nonhuman (Newman, 1985) primates.…”

In the current revival of interest in the emotional and mental lives of animals, many investigators have focused attention on mammalian infants that emit distress vocalizations when separated from the home environment. Perhaps the most intensively studied distress vocalization is the ultrasonic vocalization of infant rats. Since its discovery, this vocalization has been interpreted both as a communicatory signal for the elicitation of maternal retrieval and as the manifestation of emotional distress. In contrast, the authors examined the cardiovascular causes and consequences of the vocalization, and on the basis of this work, they hypothesized that the vocalization is the acoustic by-product of the abdominal compression reaction (ACR), a maneuver that results in increased venous return to the heart. Therefore, the vocalization may be analogous to a sneeze, serving a physiological function while incidentally producing sound.

“…These vocalizations have received extensive analysis (cf. Andrew, 1969;Collias & Joos, 1952;Guyomarc'h, 1962;Rajecki, 1974;Rajecki, Eichenbaum, & Heilweil, 1973) and are known to have a number of physical differences. It is sufficient to state here that the distress call is reliably louder (above 80 decibels, generally) than any other vocalization in the bird's repertoire.…”
