Title Dimensions of horse personality based on owner and trainer supplied personality traits Type Journal Article
Year 2008 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 113 Issue 1 Pages 206-214
Keywords Horse; Personality; Domestication; Five-factor model
Abstract Ratings on 36 personality descriptive adjectives were made on 100 companion horses by owners, trainers, and stable managers. The descriptors had been previously provided by a subset of 30 raters based on their own experience with horses. Principal components analysis revealed three statistically significant factors accounting for 59% of the variance. The first was a large, complex factor resembling the human Agreeableness factor. This factor contained four clusters of items reflecting obedience, kindness, sociality, and non-aggressiveness. The second factor resembled human Extraversion, although it also contained items reflecting intellect and curiosity. The third factor reflected Neuroticism or Emotionality. Factors similar to Agreeableness, Extraversion, and Emotionality are frequently observed in other taxa. The diverse composition of the Agreeableness factor indicating covariation among obedience, kindness, sociality, and non-aggressiveness may be a result of the intense artificial selection for all four components during the 6000 years of horse domestication.

Title Trauma history and severity of gambling involvement among horse-race gamblers in a South African gambling setting Type Journal Article
Year 2006 Publication Psychological Reports Abbreviated Journal Psychol Rep
Volume 99 Issue 2 Pages 472-476
Keywords Adult; African Continental Ancestry Group/*psychology/statistics & numerical data; Aged; Aged, 80 and over; Cross-Sectional Studies; Female; Gambling/*psychology; Humans; *Life Change Events; Male; Middle Aged; Personality Inventory; Risk Factors; *Social Environment; Socioeconomic Factors; South Africa; Statistics; Stress Disorders, Post-Traumatic/epidemiology/*psychology
Abstract The purpose of this study was to ascertain the frequency of gambling involvement and the prevalence of problem gambling among horse race gamblers and to discover whether problem gambling in this sample is associated with a history of trauma. Among a sample of 266 South African horse-race gamblers (94% men and 6% women, Mage 46.8 yr., SD = 13.9, range 18-85 years), 31.2% were classified as probable pathological gamblers and 19.9% with problem gambling. Major weekly gambling activities included racetrack betting (82%), purchase of lottery tickets or scratch tickets (35%), purchase of sports lottery tickets (23%), and using casino type games (18%). Trauma history was significantly associated with gambling severity.

Title Responses of horses in behavioural tests correlate with temperament assessed by riders Type Journal Article
Year 2003 Publication Equine Veterinary Journal Abbreviated Journal Equine Vet J
Volume 35 Issue 2 Pages 176-183
Keywords Adult; Animals; *Behavior, Animal/physiology; Data Interpretation, Statistical; Female; *Handling (Psychology); Heart Rate/*physiology; Horses/physiology/*psychology; Humans; Male; Personality; Temperament/*physiology
Abstract REASONS FOR PERFORMING STUDY: Behavioural tests as well as observers' ratings have been used to study horses' temperament. However, the relationship between the ratings and the responses in behavioural tests has not yet been studied in detail. OBJECTIVES: The aim of the present study was to examine this relationship between ratings and responses. METHODS: Eighteen mature Swedish Warmblood horses were subjected to 2 behavioural tests, one relating to novelty (novel object test) and one to handling (handling test). Subsequently, 16 of these horses were ridden by 16 equally experienced students, having no former experience with the horses. Immediately after each ride, the students scored the horse for 10 temperamental traits using a line rating method. RESULTS: It was shown that for each temperamental trait all 16 riders agreed on the ranking of the horses (0.212<W<0.505, P < 0.001). CONCLUSIONS: Correlations between behavioural and heart rate variables in the behavioural tests revealed that horses with a high level of locomotion or much restlessness behaviour exhibited high mean heart rate and low heart rate variability. In particular, heart rate variables in the behavioural tests were found to correlate with riders' rating scores. Furthermore, the underlying components of the handling test, retrieved with a principal component analysis (PCA) correlated with riders' rating scores while the underlying components of the novel object test did not. POTENTIAL CLINICAL RELEVANCE: It is concluded that it is possible for a large panel of assessors to agree upon a horse's temperament and that objective measures from behavioural tests correlate significantly with temperamental traits assessed by a panel of assessors.
