Title Repeatability and comparison of two maze tests to measure learning ability in horses Type Journal Article
Year 1986 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 16 Issue 2 Pages 103-119
Keywords
Abstract Sixteen Quarter Horses were randomly divided into two groups after sorting by age and sex. After a 10-day preconditioning period, each animal was scored for emotionality and trainability. Each group then completed a series of learning tasks in a modified T-maze for 20 consecutive days. Group P/D was initially tested on a simple place-learning task, while Group D/P was trained in a visual discrimination task. The groups were tested alternately on the two tasks with 10-day extinction periods between each task. Upon reaching a criterion of 11 of 12 correct responses (the last 8 responses consecutive), a horse was retired for the day. If this criterion was not attained, the horse completed 20 trials. Learning occurred at a faster rate on the discrimination tasks compared to the gradual learning curves observed on place tasks. Animals learned more rapidly and reached higher levels of performance as the series of tasks progressed. Trainability and emotionality scores tended to predict the final level of learning achieved. Correlations of performance ranks within emotionality and training groups were higher between tasks of the same type than between the different tasks. Rank correlations between odd and even days on each task indicated that the within-group rankings were more consistent on the discrimination task than on the place task.

Title Observational learning of two visual discriminations by pigeons: a within-subjects design Type Journal Article
Year 1986 Publication Journal of the experimental analysis of behavior Abbreviated Journal J Exp Anal Behav
Volume 46 Issue 1 Pages 45-49
Keywords Animals; Attention; Columbidae; Conditioning, Operant; Cues; *Discrimination Learning; *Imitative Behavior; Male; Visual Perception
Abstract Pigeon's observational learning of successive visual discrimination was studied using within-subject comparisons of data from three experimental conditions. Two pairs of discriminative stimuli were used; each bird was exposed to two of the three experimental conditions, with different pairs of stimuli used in a given bird's two conditions. In one condition, observers were exposed to visual discriminative stimuli only. In a second condition, subjects were exposed to a randomly alternating sequence of two stimuli where the one that would subsequently be used as S+ was paired with the operation of the grain magazine. In a third experimental condition, subjects were exposed to the performance of a conspecific in the operant discrimination procedure. After exposures to conspecific performances, there was facilitation of discriminative learning, relative to that which followed exposures to stimulus and reinforcement sequences or exposures to stimulus sequences alone. Exposure to stimulus and food-delivery sequences enhanced performance relative to exposure to stimulus sequences alone. The differential effects of these three types of exposure were not attributable to order effects or to task difficulty; rather, they clearly were due to the type of exposure.

Title Conflict between red deer hinds: the winner always wins Type Journal Article
Year 1986 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 34 Issue 4 Pages 1166-1171
Keywords
Abstract Dominance relations between free-living, female red deer (hinds) (Cervus elaphus L.) on the Isle of Rhum, Scotland, were investigated. Most interactions were won by the older hind of the pair and this was the case even when both individuals had reached full body size. The younger hind was more likely to be the winner if the conflict was escalated or if the two hinds were strangers, in which case escalation was more frequent than usual. When outside their normal home range, older hinds were much more likely to lose, and younger ones more likely to win, than usual. These results can be best explained by the hinds using previous experience as a cue for conventional resolution of conflict, with the result that dominance relationships established early in life are perpetuated. No such cue is available if the hinds have not previously met.

Title Wild Horses of the Great Basin: Social Competition and Population Size Type Book Whole
Year 1986 Publication Abbreviated Journal
Volume Issue Pages
Keywords Wildlife Behavior Ecology
Abstract Editorial Reviews

From Library Journal

Berger begins this scholarly and absorbing treatise by discussing the natural history of the horse in general. Then, on the basis of several years of field work, he describes and details the behavior and ecology of the wild horses in the Great Basin Desert of Nevada. The purpose of the book is not, however, merely to describe natural history, but also to test quantitatively several basic ecological hypotheses. Berger has done both well, and his book will be a major source of information on North American wild horses for years to come. The book will interest specialists and graduate students primarily. It may also appeal to anyone with a strong interest in wild horses, and the remote and starkly beautiful Great Basin. Nicholas J. Volkman, Point Reyes Bird Observatory, Stinson Beach, Cal.

Title Mutual grooming and nearest-neighbor relationships among foals of Equus caballus Type Journal Article
Year 1986 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 15 Issue 2 Pages 113-123
Keywords
Abstract A 3-year study was carried out on the developmental behavior of foals from birth to 24 weeks of age and the behavior of mares living with foals. Mutual-grooming partners of foals were primarily other foals. The peak frequency of mutual grooming occurred during Weeks 9-12, when fillies mutual-groomed 1.6 times h-1 and colts mutual-groomed 0.9 times h-1. Fillies mutual-groomed more frequently than colts (P < 0.025). Fillies mutual-groomed randomly with colts and other fillies (P < 0.05), whereas colts mutual-groomed almost exclusively with fillies (P = 0.03). At all ages studied, if a foal's nearest neighbor was not its mother, it was more likely to be another foal than would be expected if the foal was associating randomly with non-mother ponies. Fillies were more likely than expected to have a filly rather than a colt as their nearest neighbor (P = 0.01). Thus, during their first few months of life, the foals studied exhibited patterns of behavior which were consistent with the development of the usual social milieu of unmanaged adults, in which several mares form a cohesive herd with one or more stallions associating with them.
