Abstract |
Covering a wide range of key topics, from reasoning and communication to sensation and complex problem-solving, this engagingly-written text presents a comprehensive survey of contemporary research on animal cognition. Written for anyone with an interest in animal cognition, but without a background in animal behaviour, it endeavours to explain what makes animals tick.
With numerous illustrations and including exciting recent studies from many little-studied species (such as the weakly electric African fish), this text is ideal for psychology students who are interested in how much of our human cognition is shared by other species, for students of biology who want to know how complex animal behaviour can get, and for all those with an interest in the animal mind. |

Abstract |
Identification of horses with hot iron branding is one of the most controversial issues in German horse breeding and also discussed in other countries. Traditionally horses have been identified by hot iron branding with breed-specific symbols and additional numbers. Since 2009, European Union legislation requires that all horses born after that year must have a microchip implanted for identification, although some exceptions are possible. So far it has not been tested using scientific criteria to what extent branding and microchips reliably allow identification of individual horses. In this study, the readability of branding symbols and numbers was analyzed by 3 independent investigators in 248 horses participating in an equestrian competition. Microchip transponders implanted into the neck were read in another 182 horses on different breeding farms. Microchip readings were made on both sides of the neck and 3 different commercially available ISO 11785/11785 scanners were compared (A: Minimax II, B: I-MaxPlus, C: Isomax V, all by Virbac, Germany). Correct reading of the branding breed symbol in horses at an equestrian championship by the individual investigators was close to 90% and differed only marginally between the investigators. Correct identification of the breed-specific symbol by all 3 investigators occurred in 84% of cases. The double-digit number branded together with the breed symbol was identified correctly by all 3 investigators in 39% of cases with correct readings by individual investigators ranging from 47 to 54%. Correct identification of the branding signs did not differ significantly between horses of different coat color and age group. Readability of microchips differed between scanners. Best results were obtained with scanner C which allowed microchip reading on the implantation side in 100% and on the contralateral side of the neck in 95% of 182 horses. Time for location of the microchip on the implanted side ranged from 1 to 4 sec (1.1±0.4). Scanner A identified 92 and 25% of microchips on the implanted and contralateral side, respectively while corresponding values for scanner B were 86 and 20%. Readability of microchip transponders on the side contralateral to implantation was influenced by size and thus caliber of the horse. In conclusion, hot iron branding does not allow unique identification of horses and individual branding numbers can be read in less than 40% of the horses. Readability of microchip transponders is more reliable compared to hot iron branding but depends on the type of scanner used. Scanner C allowed identification of all horses tested and gave good results also when used on the contralateral side of the horses` neck. KW - |

Abstract |
In this study, the behaviour of Shetland pony foals after weaning was analysed. Foals were either weaned simultaneously (group SW; n=7) by removing all mares at the same time and leaving the foals as a group or foals were weaned consecutively (group CW; n=4) by removing one mare per day on consecutive days. Behaviour of the foals was observed 3 times per day (6:00-8:00, 12:00-14:00 and 18:00-20:00) from one day before weaning to 7 days (group SW) or 10 days (group CW) after removing the first mare. Vocalisation after removal mares was more frequent in foals weaned simultaneously (d 1: SW 66±37 per 2 hrs) than when mares were removed consecutively at one-day intervals (d1, i.e. removal of first mare: CW 3±2 per 2 hrs). In CW foals, vocalisation was most frequent on the day after removal of the last mare (day 5: 18±6 per 2 hrs), although it was lower than in SW foals on day 1 after weaning. Locomotor activity was highest in SW foals on days 1 and 2 after weaning (maximum 17±6 movements per 2 hrs, p<0.05 vs. CW: <2 movements per 2 hrs at all times). Frequency of defaecation increased to 7±1 per 2 hrs on day 1 after SW (p<0.05 vs. group CW), it was 3±2 per 2 hrs in group CW at the time 3 mares had been removed and was below 2 at all other times in both groups. The time, foals spent in lateral recumbency and in sternal recumbency was reduced to near zero during the two days following weaning (group SW) and the period during which mares were removed consecutively (group CW). Tactile contact between foals was increased in SW foals after weaning compared to CW foals during the period of consecutive weaning. Suckling on other foals increased in both groups for several days after weaning but did not differ between groups. No major changes over time or differences between groups were found for other behaviour parameters. Foals weaned simultaneously lost weight slightly but significantly (p<0.05) within two days after weaning (from 78±11 to 75±10) while no weight loss occurred in CW foals. In conclusion, SW elicited more pronounced behavioural changes than CW in pony foals. Consecutive weaning can be considered a more gentle method than SW and thus may be associated with lower risks and less stress for the foals. |

Abstract |
A computational theory of primate social intelligence is proposed in which primates represent social situations internally by discrete symbol structures, called scripts. Three well-defined computational operations on scripts are sufficient to support social learning, planning, and prediction. This gives a formal, predictive model with which to analyse how primate social knowledge is acquired, as well as how it is used. The theory is compared with primate data, such as Cheney and Seyfarth's observations of vervet monkeys. It gives simple, understandable script-based analyses of many observed phenomena--such as the recognition and use of kin relations, learning of alarm calls, habituation to calls, knowledge of rank, tactical deception, and attachment behaviour. I argue that a tight, concise theory of social cognition, such as script theory, is needed to explain the rapid learning and social guile seen in primates. It also has the benefits of simplicity and testability. The extension of scripts to incorporate a primate theory of mind is described in a subsequent paper. |
