Title | Modification of reconciliation behavior through social experience: an experiment with two macaque species | Type | Journal Article | ||
Year | 1993 | Publication | Child development | Abbreviated Journal | Child Dev |
Volume | 64 | Issue | 3 | Pages | 897-908 |
Keywords | Aggression; Animals; *Behavior, Animal; Female; Grooming; *Macaca; *Macaca mulatta; Male; Play and Playthings; *Socialization; Vocalization, Animal | ||||
Abstract | Reconciliation, defined as a friendly reunion between former opponents shortly after an aggressive encounter, is common in the stumptail macaque (Macaca arctoides) but rare in the rhesus macaque (M. mulatta). Juveniles of the two species were cohoused for 5 months, after which they were observed with conspecifics only. Control rhesus monkeys, matched in age and sex to the experimental subjects, went through the same procedure without exposure to the other species. A threefold increase in the proportion of reconciled fights was measured in the rhesus subjects. The difference emerged gradually during cohousing with the tutor species and was sustained following removal of this species. Other behavior, such as grooming and aggression, decreased over time. It is suggested that the social attitude of the subjects was affected through contact with a species characterized by a more relaxed dominance style. | ||||

Title | Directed forgetting in animals | Type | Journal Article | ||
Year | 1993 | Publication | Psychological bulletin | Abbreviated Journal | Psychol Bull |

Abstract | Directed-forgetting research with animals suggests that animals show disrupted test performance only under certain conditions. Important variables are (a) whether during training, the cue to forget (F cue) signals nonreward (i.e., that the trial is over) versus reward (i.e., that reinforcement can be obtained) and (b) given that reinforcement can be obtained on F-cue trials, whether the post-F-cue response pattern is compatible with the baseline memory task. It is proposed that some findings of directed forgetting can be attributed to trained response biases, whereas others may be attributable perhaps to frustration-produced interference. It is suggested that directed forgetting in animals should be studied using procedures similar to those used to study directed forgetting in humans. This can be accomplished by presenting, within a trial, both to-be-remembered and to-be-forgotten material. | ||||

Title | Varieties of learning and memory in animals | Type | Journal Article | ||
Year | 1993 | Publication | Journal of experimental psychology. Animal behavior processes | Abbreviated Journal | J Exp Psychol Anim Behav Process |
Volume | 19 | Issue | 1 | Pages | 5-14 |
Keywords | Animals; Association Learning; Birds; Conditioning, Classical; Evolution; Imprinting (Psychology); *Learning; *Memory; Social Environment; Species Specificity; Taste | ||||
Abstract | It is often assumed that there is more than one kind of learning--or more than one memory system--each of which is specialized for a different function. Yet, the criteria by which the varieties of learning and memory should be distinguished are seldom clear. Learning and memory phenomena can differ from one another across species or situations (and thus be specialized) in a number of different ways. What is needed is a consistent theoretical approach to the whole range of learning phenomena, and one is explored here. Parallels and contrasts in the study of sensory systems illustrate one way to integrate the study of general mechanisms with an appreciation of species-specific adaptations. | ||||

Title | Proximate causes of natal dispersal in feral ponies: some sex differences | Type | Journal Article | ||
Year | 1993 | Publication | Animal Behaviour. | Abbreviated Journal | Anim. Behav. |
Volume | 46 | Issue | 5 | Pages | 969-975 |
Keywords | |||||
Abstract | Abstract. Fifteen years of data on natal dispersal age and the context of dispersal for the feral ponies of Assateague Island, Maryland are presented. Ninety-seven per cent of males and 81% of females dispersed from their natal groups by 5 years of age. For animals that left their natal group, average age of dispersal was 20[middle dot]8 months for males and 24[middle dot]6 months for females. Male dispersal age was strongly and significantly correlated with number of peers in the natal group, and males dispersing with peers were significantly older than males dispersing without peers, suggesting that males delayed dispersal when peers were available for interaction. Female dispersal age was not influenced by number of peers, but was correlated with age of first reproduction. Factors not influencing dispersal age in either sex were presence of a younger sibling, maternal band transfers, and maternal age and dominance rank. The relatively high frequency of females failing to disperse from their natal groups is puzzling in light of data showing diminished fecundity in non-dispersing pony mares. | ||||

Title | Search behavior of dogs (Canis familiaris) in invisible displacement problems | Type | Journal Article | ||
Year | 1993 | Publication | Animal Learning & Behavior | Abbreviated Journal | Anim Learn. & Behav. |
Volume | 21 | Issue | 3 | Pages | 246-254 |
Keywords | |||||
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. |
