Qualitative and quantitative changes in dogs' information-seeking behaviours during the subsequent phases of operant conditioning training using a scent lineup, were investigated. Particular interest was paid to behaviours which may have an impact on errors committed by dogs at work in a scent lineup and thus on the reliability of the canine identification of humans on the base of scent. Significant individual differences were found in dogs' performance in operant conditioning during match-to-sample trials. The style and time of sniffing the pattern scent sample as well as the searching time and number of stations sniffed in the lineup were found to influence the percentage of errors (false positive and false negative indications) made by dogs. The effects of the dogs' routine e.g. omitting stations, using other cues than olfactory ones (visual) and effects of the non-verbal communications between handler and dog have been discussed.

The main aim of the two-stage studies was to establish the structure of the personality traits that are attributed to domestic animals by their owners. 1279 associations were collected in a qualitative study of 154 participants who described their domestic animals: dogs or cats. The lexical taxonomy of associations was performed by 7 judges. The frequency analysis allowed isolating 50 personality descriptors which are most often used by the owners describing their domestic animals. This adjective list was completed by 400 persons (age range: 15-85; 200 cat owners and 200 dog owners). A principal component analysis and a confirmatory factor analysis distinguished six dimensions: Energy, Intellect, Friendliness, Conscientiousness, Agreeableness, and Antisocial dimension. A structural equations analysis established that the structures of personality characteristics attributed to dogs, cats and self-rating of their owners were similar. A short scale, of good psychometric validity, was compiled for further studies on perceived personality of domestic animals.
