Title | Personality differences explain leadership in barnacle geese | Type | Journal Article | ||
Year | 2009 | Publication | Animal Behaviour. | Abbreviated Journal | Anim. Behav. |
Volume | 78 | Issue | 2 | Pages | 447-453 |
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 | Quantifying personality in the terrestrial hermit crab: Different measures, different inferences | Type | Journal Article | ||
Year | 2012 | Publication | Behavioural Processes | Abbreviated Journal | Behav. Process. |
Volume | 91 | Issue | 2 | Pages | 133-140 |
Keywords | Animal personality; Behavioral syndrome; Hermit crabs | ||||
Abstract | There is much interest in studying animal personalities but considerable debate as to how to define and evaluate them. We assessed the utility of one proposed framework while studying personality in terrestrial hermit crabs (Coenobita clypeatus). We recorded the latency of individuals to emerge from their shells over multiple trials in four unique manipulations. We used the specific testing situations within these manipulations to define two temperament categories (shyness-boldness and exploration-avoidance). Our results identified individual behavioral consistency (i.e., personality) across repeated trials of the same situations, within both categories. Additionally, we found correlations between behaviors across contexts (traits) that suggested that the crabs had behavioral syndromes. While we found some correlations between behaviors that are supposed to measure the same temperament trait, these correlations were not inevitable. Furthermore, a principal component analysis (PCA) of our data revealed new relationships between behaviors and provided the foundation for an alternate interpretation: measured behaviors may be situation-specific, and may not reflect general personality traits at all. These results suggest that more attention must be placed on how we infer personalities from standardized methods, and that we must be careful to not force our data to fit our frameworks. | ||||

Title | Kosten-Nutzen-Analyse einer objektivierten Temperamentbeurteilung bei Pferden [Economic evaluation of an objective temperament assessment in horses] | Type | Journal Article | ||
Year | 2013 | Publication | Züchtungskunde | Abbreviated Journal | |
Volume | 85 | Issue | 2 | Pages | 129-142 |

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.] |

Title | Evaluation of a novel method of horse personality assessment: Rater-agreement and links to behaviour | Type | Journal Article | ||
Year | 2007 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |

Abstract | The efficacy of questionnaire-based personality assessment has been shown in a variety of animal and human personality studies. There has been a recent increase in questionnaire-based studies focussing on equine personality but with a lack of comparability to studies on other species. The aim of this study was to test the reliability of an assessment method originally developed for primates and demonstrate reliability using three criteria (1) assessments by independent observers must agree with one another, (2) these assessments must predict behaviours and real-world outcomes and (3) observer ratings must be shown to reflect genuine attributes of the individuals rated, not merely the observer's implicit personality theories about how traits co-vary. The personality of 61 horses (Equus caballus) was assessed using a questionnaire constructed of 30 behaviourally defined adjectives (BDAs). Horses were each assessed by three judges, in addition to a total of 2 h behaviour observations recorded per horse. Rater agreement was demonstrated for 72.1% of the horses and 25 of the BDAs. Principal component analysis was carried out on the rating data and revealed six underlying personality components that were labelled “dominance”, “anxiousness”, “excitability”, “protection”, “sociability” and “inquisitiveness”. Component scores for horses were correlated against behavioural observations for the same horses and revealed significant correlations with 20 of the recorded behaviour variables. Correlations between specific components and their associated behaviours were logical and consistent with the types of behaviours that would be expected to be linked with such personality types. The data were shown to meet all three criteria and provided strong evidence that the assessment method was reliably measuring horse personality. | ||||

Title | Horses' learning performances are under the influence of several temperamental dimensions | Type | Journal Article | ||
Year | 2010 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |
Volume | 125 | Issue | 1-2 | Pages | 30-37 |
Keywords | Avoidance task; Equus caballus; Fearfulness; Learning; Personality; Temperament | ||||
Abstract | Learning performances are influenced by many factors, not only breed, age and sex, but also temperament. The purpose of this study was to understand how different temperamental dimensions affect the learning performance of horses, Equus caballus. First, we carried out a series of behavioural tests on 36 Welsh ponies aged 5-7 years to measure five temperamental dimensions: fearfulness (novel area test and surprise test), gregariousness (social isolation test), reactivity to humans (passive human test), tactile sensitivity (von Frey filament test) and activity level (evaluation of locomotor activity during all the tests). We then presented them with two learning tasks (avoidance and backwards-forwards tasks). In the avoidance task they had to learn to jump over a fence when they heard a sound associated with an aversive stimulus (puff of air). In the backwards-forwards task they had to walk forwards or move backwards in response to a tactile or vocal command to obtain a food reward. There was no correlation between performances on the two learning tasks, indicating that learning ability is task-dependent. However, correlations were found between temperamental data and learning performance (Spearman correlations). The ponies that performed the avoidance task best were the most fearful and the most active ones. For instance, the number of trials required to perform 5 consecutive correct responses (learning criterion) was correlated with the variables aimed at measuring fearfulness (way of crossing a novel area: rs = -0.41, P = 0.01 and time to start eating again after a surprise effect: rs = -0.33, P = 0.05) and activity level (frequency of trotting during all the tests: rs = -0.40, P = 0.02). The animals that performed the backwards-forwards task best were the ones that were the least fearful and the most sensitive. For instance, the learning criterion (corresponding to the number of trials taken to achieve five consecutive correct responses) was correlated with the variables aimed at measuring fearfulness (latency to put one foot on the area: rs = 0.43, P = 0.01; way of crossing a novel area: rs = 0.31, P = 0.06; and time to start eating again after a surprise effect: rs = 0.43, P = 0.009) and tactile sensitivity (response to von Frey filaments: rs = -0.44, P = 0.008). This study revealed significant links between temperament and learning abilities that are highly task-dependent. | ||||

Title | Empathy: Its ultimate and proximate bases | Type | Journal Article | ||

Abstract | There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cognitive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mechanism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors (e.g., alarm, social facilitation, vicariousness of emotions, mother-infant responsiveness, and the modeling of competitors and predators) that are crucial for the reproductive success of animals living in groups. The Perception-Action Model (PAM), together with an understanding of how representations change with experience, can explain the major empirical effects in the literature (similarity, familiarity, past experience, explicit teaching, and salience). It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empathy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of development, and situations. | ||||

Keywords | Animals; Animals, Domestic/*psychology; *Behavior, Animal; Cats/*psychology; Humans; *Personality | ||||
Abstract | Personality ratings of 196 cats were made by their owners using a 5-point Likert scale anchored by 1: not at all and 5: a great deal with 12 items: timid, friendly, curious, sociable, obedient, clever, protective, active, independent, aggressive, bad-tempered, and emotional. A principal components analysis with varimax rotation identified three intepretable components. Component I had high loadings by active, clever, curious, and sociable. Component II had high loadings by emotional, friendly, and protective, Component III by aggressive and bad-tempered, and Component IV by timid. Sex was not associated with any component, but age showed a weak negative correlation with Component I. Older animals were rated less social and curious than younger animals. | ||||
