| Year | Publication | Social Behavior in Farm Animals | Abbreviated Journal | ||
| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | An understanding of social behavior is increasingly necessary in farm animal husbandry as more animals are housed in groups rather than in individual stalls or pens. There may be economic or welfare reasons for such housing. This book is the first to specifically address this important subject. The chapters fall into three broad subject areas: concepts in social behavior; species specific chapters; current issues. Authors include leading experts from Europe, North America, Australia and New Zealand. | ||||

| Title | Group fusion: the impact of winner, loser, and bystander effects on hierarchy formation in large groups | Type | Journal Article | ||

| Volume | 14 | Issue | 3 | Pages | 367-373 |

| Abstract | We present the results of a series of computer simulations that examined the impact of winner, loser, and bystander effects on hierarchy formation in fused groups. These effects and their implications for hierarchy structure and aggressive interactions were first examined in small four-member groups. Subsequent to this, the two small groups were fused into a single larger group. Further interactions took place in this fused group, generating a new hierarchy. Our models demonstrate clearly that winner, loser, and bystander effects strongly influence both the structure and types of interactions that emerge from the fusion of smaller groups. Four conditions produced results in which the same general patterns were uncovered in pre- and postfusion groups: (1) winner effects alone, (2) bystander loser effects alone, (3) winner and bystander winner effects operating simultaneously, and (4) all four effects in play simultaneously. Outside this parameter space, hierarchy structure and the nature of aggressive interactions differed in pre- and postfusion groups. When only loser effects were in play, one of the two clear alphas from the prefused groups dropped in rank in the eight-member fused group. When bystander winner effects were in play, it was difficult to rank any of the eight individuals in the fused group, and players interacted almost exclusively with those that were not in their original four-member group. When loser and bystander loser effects operated simultaneously, two top-ranking individuals emerged in the fused groups, but the relative rank of the other players was difficult to assign. | ||||

| Title | Tendency to inspect predators predicts mortality risk in the guppy (Poecilia reticulata) | Type | Journal Article | ||
| Year | 1992 | Publication | Behavioral Ecology | Abbreviated Journal | Behav. Ecol. |
| Volume | 3 | Issue | 2 | Pages | 124-127 |
| Keywords | |||||
| Abstract | Although predator inspection behavior in fishes has become a model system for examining game theoretical strategies such as Tit for Tat, the direct costs of inspection behavior have not been quantified. To begin quantifying such costs, I conducted an experiment that examined mortality due to predation as a function of predator inspection in the guppy (Poecilia reticulata). Before being subjected to a “survivorship” experiment, guppies were assayed for their tendency to inspect a predator. Groups were then composed of six guppies that differed in their tendency to inspect. These groups were placed into a pool containing a predator, and survivorship of guppies with different inspection tendencies was noted 36 and 60 h later. Results indicate that individuals that display high degrees of inspection behavior suffer greater mortality than their noninspecting shoalmates. | ||||

| Title | Search behavior in cats and dogs Interspecific differences in working memory and spatial cognition | Type | Journal Article | ||
| Year | 1996 | Publication | Animal Learning & Behavior | Abbreviated Journal | Anim Learn. & Behav. |
| Volume | 24 | Issue | 2 | Pages | 142-149 |
| Keywords | |||||
| Abstract | Cats and dogs search behavior was compared in different problems where an object was visibly moved behind a screen that was then visibly moved to a new position. In Experiments 1 (cats) and 2 (dogs), one group was tested with identical screens and the other group was tested with dissimilar screens. Results showed that in both species, search behavior was based on processing of spatial information rather than on recognition of the visual features of the target screen. Cats and dogs were unable to find the object by inferring its invisible movement. They reached a high level of success only if there was direct perceptual evidence that the object could not be at its initial position. When the position change was indicated by an indirect cue, cats searched more at the object`s initial than final position, whereas dogs searched equally at both positions. Interspecific similarities and differences are interpreted in terms of the requirements for resetting working memory. |

| Abstract | Gagnon and Dor (1992) showed that domestic dogs are able to solve a Piagetian object permanence task called the invisible displacement problem. A toy is hidden in a container which is moved behind a screen where the toy is removed and left. Dogs make more errors in these problems than they do in visible displacement tests, in which the object is hidden directly behind the target screen. In Experiment 1, we examinedcomponents ofthe standard procedure of invisible displacements that may make encoding or retention of the hiding location more difficult than it is in visible displacements. In Experiment 2, we compared dogs performances in visible and invisible displacement problems when delays of 0, 10, and 20 sec were introduced between the objects final disappearance and the subjects release. The results revealed that dogs poorer performance in invisible displacement tests is related to the complex sequence of events that have to be encoded or remembered as well as to a difficulty in representing the position change that is signaled, but not directly perceived. |

| Title | Social Learning in Animals: Sex Differences and Neurobiological Analysis | Type | Journal Article | ||

| Abstract | Social learning where an “individual's behavior is influenced by observation of, or interaction with, another animal or its products” has been extensively documented in a broad variety of species, including humans. Social learning occurs within the complex framework of an animal's social interactions that are markedly affected by factors such as dominance hierarchies, family bonds, age, and sex of the interacting individuals. Moreover, it is clear that social learning is influenced not only by important sexually dimorphic social constraints but also that it involves attention, motivational, and perceptual mechanisms, all of which exhibit substantial male-female differences. Although sex differences have been demonstrated in a wide range of cognitive and behavioral processes, investigations of male-female differences in social learning and its neurobiological substrates have been largely neglected. As such, sex differences in social learning and its neurobiological substrates merit increased attention. This review briefly considers various aspects of the study of social learning in mammals, and indicates where male-female differences have either been described, neglected and, or could have a potential impact. It also describes the results of neurobiological investigations of social learning and considers the relevance of these findings to other sexually dimorphic cognitive processes. | ||||

| Abstract | Processing of serial information was assessed by training six macaques on a five-item list of objects arranged into the four conditional pairs, A-B+, B-C+, C-D+, and D-E+. An analogous list (F through J) was similarly trained. Subsequently, both lists were linked by training on E-F+, a pair that provided adjacent elements from each list. Then, all unique and trained object pairs from both lists were presented as a test. Results indicated that the objects were retained as a single, linearly organized list with choice accuracy directly related to interitem distance between paired objects. A second experiment explored the consequences of incidence of conflicting information on list organization. In both experiments, selections depended on representational processes and supported the view that monkeys and pigeons retain serial lists in qualitatively different ways. | ||||
