Abstract: Group foragers may be able to assess patch quality more efficiently by paying attention to the sampling activities of conspecifics foraging in the same patch. In a previous field experiment, we showed that starlings foraging on patches of hidden food could use the successful foraging activities of others to help them assess patch quality. In order to determine whether a starling could also use another individual's lack of foraging success to assess and depart from empty patches more quickly, we carried out two experimental studies which compared the behaviour of captive starlings sampling artificial patches both when alone and when in pairs. Solitary starlings were first trained to assess patch quality in our experimental two-patch system, and were then tested on an empty patch both alone and with two types of partner bird. One partner sampled very few holes and thus provided a low amount of public information; the other sampled numerous holes and thus provided a high amount of public information. In experiment 1, we found no evidence of vicarious sampling. Subjects sampled a similar number of empty holes when alone as when with the low and high information partners; thus they continued to rely on their own personal information to make their patch departure decisions. In experiment 2, we modified the experimental patches, increasing the ease with which a bird could watch another's sampling activities, and increasing the difficulty of acquiring accurate personal sampling information. This time, subjects apparently did use public information, sampling fewer empty holes before departure when with the high-information partner than when with the low-information partner, and sampling fewer holes when with the low-information partner than when alone. We suggest that the degree to which personal and public information are used is likely to depend both on a forager's ability to remember where it has already sampled and on the type of environment in which foraging takes place.

Abstract: Synopsis
Does a young chimpanzee's gaze subjectively link it to the outside world? Is seeing “about” something to this species? This volume reports the results of fifteen studies conducted with chimpanzees and preschool children. The findings provide little evidence that young chimpanzees understand seeing as a mental event. Even though young chimps spontaneously attend to and follow the visual gaze of others, they simultaneously appear oblivious to the attentional significance of that gaze. This interpretation is consistent with three different possibilities: chimpanzees may experience a delay in psychological development; alternatively, they may possess a different theory of attention, connected subjectively through other behavioral indicators; or the subjective understanding of visual perception may only be present in humans.

Davis, M. H. (1996). Empathy: A Social Psychological Approach. Boulder, CO: Westview Press.
Abstract: Product Description
Empathy has long been a topic of interest to psychologists, but it has been studied in a sometimes bewildering number of ways. In this volume, Mark Davis offers a thorough, evenhanded review of contemporary empathy research, especially work that has been carried out by social and personality psychologists.Davis’ approach is explicitly multidimensional. He draws careful distinctions between situational and dispositional “antecedents” of empathy, cognitive and noncognitive “internal processes,” affective and nonaffective “intrapersonal outcomes,” and the “interpersonal behaviora
l outcomes” that follow. Davis presents a novel organizational model to help classify and interpret previous findings. This book will be of value in advanced undergraduate and graduate courses on altruism, helping, nad moral development.

Abstract: The present study examined both human and horse heart rates (HRs) when humans stroked horses for 90 seconds; the subjective arousal levels of the humans were measured by the Tohoku Activation Deactivation Adjective Check List before and after stroking horses. Six male subjects with a positive attitude toward companion animals and 6 male subjects with a negative attitude were selected by their scores on the Pet Attitude Scale, and these two groups, together with a third group, of 6 subjects who were male members of the Doshisha University horse-riding club, participated in this experiment. The HRs of the human subjects during the first 10 seconds immediately after the stroking began were significantly higher than those obtained after that period, but these higher levels gradually returned to baseline levels. This tendency appears more clearly in the negative attitude group. The HRs of the horses increased during the first 20 seconds immediately after the human subjects of the NA group started stroking them, but gradually reduced as the stroking continued. The results of subjective arousal levels suggest a decrease in tension by stroking horses. These results suggest that a certain affectional interaction may exist between humans and companion animals.
