| Abstract | Das Ziel der vorliegenden Studie war die Ermittlung der Kosten eines Verhaltenstests zur objektiven Temperamentbeurteilung. Sie wurde an 1028 Pferden auf 55 Zuchtveranstaltungen und Privatbetrieben ermittelt. Weiterhin wurde eine Befragung zur allgemeinen Akzeptanz einer solchen Beurteilung bei Reitpferden durchgeführt. Zusätzlich wurde mit Hilfe einer Online-Umfrage die Meinung zu den Kosten und dem Aufwand einer solchen Beurteilung ermittelt. Die Kosten der Einführung einer objektiven Temperamentbeurteilung entsprechen nach Einbeziehung aller Faktoren ca. 18 Euro je Pferd. Den Kosten steht die Zahlungsbereitschaft für eine verbesserte, da objektivierte Temperamentbeurteilung gegenüber. Insgesamt 56,7% der Befragten wären bereit, mehr als 11 Euro für eine objektive Interieurbeurteilung auf Leistungsprüfungen im Feld zu investieren. Im Rahmen von Stationsprüfungen wären sie sogar bereit mehr als 30 Euro aufzuwenden. Die Wertsteigerung eines im Rahmen des Verfahrens positiv bewerteten Pferdes um 5%, die von den Teilnehmern der Umfrage durchschnittlich angenommen wird, würde zusätzlich den Gewinn beim Pferdeverkauf steigern. Die Ergebnisse zeigen, dass die Kosten einer objektiven Temperamentbeurteilung durch eine erhöhte Zahlungsbereitschaft der Käufer scheinbar kompensiert werden können, so dass die Einführung eines Temperamenttests zur objektiven Interieurbeurteilung in Form der vorgestellten Untersuchungen grundsätzlich finanzierbar ist. [The aim of the present study was to assess costs as well as riders’ acceptance of an objective temperament evaluation in riding horses. Costs were determined based on a novel object test conducted in 1028 horses tested on 65 occasions during performance tests or in private stables. In addition, an online survey was used to identify riders’ opinion about the costs and benefits of such an assessment. Based on the conditions assumed in the present study the costs for temperament testing have amount 18 Euro per horse. More than 50% of the respondents were willing to pay more than 11 Euro for an objective temperament assessment in their horses during performance tests in field. Within performance tests on station they would spend more than 30 Euro for an objective temperament assessment. Participants further assumed a rise in value of favourably assessed horses by 5%, leading to increased profits when selling the horse. In conclusion, riders appear to be willing to cover the additional costs accrued from the temperament test. Therefore, the introduction of an objective temperament assessment is likely to pay off.] |

| Abstract | For a horse to succeed in a show-jumping career, the individual has to possess both excellent physical abilities as well as a suitable personality to perform under challenging conditions. Forty-one Dutch Warmblood horses were used to develop personality tests and correlations between test variables and early training performances in jumping were studied. In behavioural tests, during the first 2 years of the horses' lives, personality aspects like emotionality, reactivity to human and learning abilities were quantified. At the age of 3, horses were broken and received early training in show-jumping. The inter-relationship between several performance variables measured during this early training phase were studied using principal component analysis (PCA). Variables measured in the different personality tests (novel-object test, handling test, avoidance-learning test and a reward-learning test) showed no correlations, suggesting that these tests all triggered different aspects of a horse's personality. This study indicates that it is possible to predict a substantial part of the show-jumping performance of an individual horse later in life by personality traits earlier in life. | ||||

| Title | Dyadic relationships and operational performance of male and female owners and their male dogs | Type | Journal Article | ||

| Abstract | In the paper we investigate how owner personality, attitude and gender influence dog behavior, dyadic practical functionality and the level of dog salivary cortisol. In three meetings, 12 female and 10 male owners of male dogs answered questionnaires including the Neo-FFI human personality inventory. Their dyadic behavior was video-taped in a number of test situations, and saliva samples were collected. Owners who scored highly in neuroticism (Neo-FFI dimension one) viewed their dogs as social supporters and spent much time with them. Their dogs had low baseline cortisol levels, but such dyads were less successful in the operational task. Owners who scored highly in extroversion (Neo-FFI dimension two) appreciated shared activities with their dogs which had relatively high baseline cortisol values. Dogs that had female owners were less sociable-active (dog personality axis 1) than dogs that had male owners. Therefore, it appears that owner gender and personality influences dyadic interaction style, dog behavior and dyadic practical functionality. | ||||

| Abstract | In animals, behavioural properties such as aggressive propensity are often consistent over a life span, and they may form part of a behavioural syndrome. We studied how aggressive propensity influences dominance, contest behaviour and growth in the cooperatively breeding cichlid fish Neolamprologus pulcher. We tested whether intrinsic aggressive propensity (1) influences dominance in paired contests, (2) causes different aggression levels in contests with partners matched for aggressive propensity compared to unmatched partners, and how it (3) affects growth rate in groups that were either matched or unmatched for aggressive propensity. Intrinsic aggressive propensity was first scored with a mirror test and classified as high, medium or low. Thereafter we tested fish with either high or low aggressive propensity with partners matched for size and either matched or unmatched for aggressive type in a paired contest for a shelter. We scored dominance, aggression and submission. As predicted, (1) dominance was more clearly established in unmatched than in matched contests and (2) individuals with high aggressive propensity launched more attacks overall than fish with low intrinsic aggressiveness, suggesting a higher propensity to escalate independently of winning or losing the paired contest. However, contrary to expectation, (3) individuals with low aggressiveness grew faster than aggressive ones in unmatched groups, whereas the opposite occurred in matched groups. This suggests that individuals with low aggressive propensity may benefit from conflict evasion, which might allow them to gain dominance in the future owing to larger body size. | ||||

| Title | Learning performances in young horses using two different learning tests | Type | Journal Article | ||
| Year | 2003 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |

| Keywords | Horse; Personality; Learning performance; Consistency; Emotionality | ||||
| Abstract | To achieve optimal performance in equine sports as well as in leisure not only the physical abilities of the horse should be considered, but also the horse's personality. Besides temperamental aspects, like emotionality, or the horse's reactivity towards humans in handling situations, the learning ability of the horse is another relevant personality trait. To study whether differences in learning performance are consistent over time and whether individual learning performance differs between learning tests or is affected by emotionality, 39 young horses (Dutch Warmblood) were tested repeatedly in two learning tests. An aversive stimulus (AS) was used in one learning test (the avoidance learning test) and a reward was used in the other learning test (the reward learning test). During both learning tests behaviour as well as heart rate were measured. Each test was executed four times, twice when horses were 1 year of age, and twice when they were 2 years of age. Half of the horses received additional physical training from 6 months onwards. In both tests horses could be classified as either performers, i.e. completing the daily session, or as non-performers, i.e. returning to the home environment without having completed the daily session. There were some indications that emotionality might have caused non-performing behaviour, but these indications are not convincing enough to exclude other causes. Furthermore, there seem to be no simple relationships between measures of heart rate, behavioural responses putatively related to emotionality and learning performance. Horses revealed consistent individual learning performances within years in both tests, and in the avoidance learning test also between years. There was no significant correlation between learning performances in the avoidance learning test and the learning performances in the reward learning test. It is concluded that individual learning abilities are consistent over a short time interval for an avoidance learning test and a reward learning test and over a longer time for the avoidance learning test. Furthermore, results indicate that some horses perform better when they have to learn to avoid an aversive stimulus while others perform better when they are rewarded after a correct response. It is suggested that these differences may be relevant to design optimal individual training programmes and methods. | ||||

| Title | Personality differences explain leadership in barnacle geese | Type | Journal Article | ||

| Keywords | barnacle goose; boldness; Branta leucopsis; group behaviour; leadership; personality | ||||
| Abstract | Personality in animal behaviour describes the observation that behavioural differences between individuals are consistent over time and context. Studies of group-living animals show that movement order among individuals is also consistent over time and context, suggesting that some individuals lead and others follow. However, the relationship between leadership and personality traits is poorly studied. We measured several personality traits and leadership of individual barnacle geese, Branta leucopsis. We measured body size and scored the dominance of individuals living in a stable group situation before subjecting them to an open-field test, an activity test, a novel-object test, and a leadership test in which the order of the movement of individuals in pairs towards a feeding patch was scored. We found high repeatability for activity and novel-object scores over time. Leadership was strongly correlated with novel-object score but not with dominance rank, activity or exploration in an open field. These results provide evidence that leadership is closely related to some aspects of personality. Interestingly, an individual's arrival at the food patch was affected not only by the novel-object score of the focal individual, but also by the novel-object score of the companion individual, indicating that movement patterns of individuals living in groups are affected by the personality traits of other group members and suggesting that movement patterns of a group may be shaped by the mix of personality types present in the group. | ||||

| Title | Individual differences in cerebral lateralization are associated with shy-bold variation in the convict cichlid | Type | Journal Article | ||

| Keywords | animal personality; Archocentrus nigrofasciatus; cerebral lateralization; convict cichlid; life history strategy; shy-bold continuum | ||||
| Abstract | Cerebral lateralization, the preferential use of one hemisphere of the brain to perform certain cognitive functions, is a widespread and evolutionarily ancient adaptation. Lateralization appears to enhance cognitive capacity, yet substantial individual variation in the strength cerebral lateralization is apparent in all species studied so far. It is puzzling that cerebral lateralization, a seemingly advantageous trait, has not been driven to fixation. It has been suggested that variation in lateralization may be linked to individual variation in behaviour, which itself may be subject to disruptive selection. We examined the relation between cerebral lateralization and individual variation in boldness in the convict cichlid, Archocentrus nigrofasciatus. We show that convict cichlids that are more strongly lateralized when exploring a familiar environment, but not a novel one, are quicker to emerge from a shelter in a test for boldness. The possibility that cerebral lateralization is linked to life history strategy is discussed. | ||||

| Keywords | behaviour prediction; bonobo; bottom-up approach; chimpanzee; gorilla; individual differences; orang-utan; personality; traits | ||||
| Abstract | Using a multidisciplinary approach, the present study complements ethological behaviour measurements with basic theoretical concepts, methods and approaches of the personality psychological trait paradigm. Its adoptability and usefulness for animal studies are tested exemplarily on a sample of 20 zoo-housed great apes (five of each of the following species): bonobos, Pan paniscus; chimpanzees, Pan troglodytes verus; gorillas, Gorilla gorilla gorilla; and orang-utans, Pongo pygmaeus abelii. Data on 76 single trait-relevant behaviours were recorded in a series of 14 laboratory-based situations and in two different group situations. Data collection was repeated completely after a break of 2 weeks within a 60-day period. All behaviour records were sufficiently reliable. Individual- and variable-oriented analyses showed high/substantial temporal stability on different levels of aggregation. Distinctive and stable individual situational and response profiles clarified the importance of situations and of multiple trait-relevant behaviours. The present study calls for a closer collaboration between behavioural biologists and personality psychologists to tap the full potential of animal personality research. | ||||
