Abstract
The Influence of Age, Sex, and Social Affiliation on the Responses of Bottlenose Dolphins (Tursiops truncatus) to a Novel Stimulus Over Time
Highlights
The novelty of an object is characterized by the difference between past and present experiences with the object, such that the greater the difference, the more novel the object (Corey, 1978)
Calves that were paired with their mothers interacted significantly more frequently with the apparatus and significantly more often in social groups than subadult and adult males who were not pair bonded with any other individuals (one-way ANOVA: F(2, 77) = 147.83, p < 0.05)
The results of this study suggest that there may be a variety of influences on the responses of bottlenose dolphins when exposed to a novel object
Summary
The novelty of an object is characterized by the difference between past and present experiences with the object, such that the greater the difference, the more novel the object (Corey, 1978). In a study conducted by Mettke-Hofmann et al (2006), more complex objects elicited a stronger behavioral response from garden warblers (Sylvia borin) than simpler objects (e.g., longer durations of exploration, stronger avoidance responses) They theorized that complex objects might be associated with a greater level of uncertainty. In a study of 10 animal species, all study subjects were more likely to interact with and orient towards novel objects presented for shorter and more variable time intervals (Kuczaj et al, 2002), and rodents, exhibited a decrease in the duration and intensity of exploratory behaviors when repeatedly exposed to a novel environment (Leussis & Bolivar, 2006)
