The research of ethologists has provided a better understanding of the mechanisms, role and development of communication behaviour between young children and their peers. However, little is known about the communication systems between children and their pets. A study of these relational systems would be needed to understand how the child interacts with his whole environment.The present study is based on the analysis of video tapes filmed during spontaneous interactions between children from 2 to 5 years of age with their pet dog (N = 45) in their home environment. Inventories were made of the child and dog behaviours during these interactions. The results have shown the different dog behaviours induced by the child and the different child behaviours induced by the dog. The links between these behaviours and the variables which characterize both partners (age, sex, etc.) were treated by factor analysis of correspondences. These data are discussed in relation to the behavioural inventories of children and dogs with their peers and conspecifics. 相似文献

Despite the prevalence of dogs as family pets and increased scientific interest in canine behavior, few studies have investigated charac- teristics of the child or dog that influence the child–dog relationship. In the present study, we explored how behavioral and some self-report measures influence a child's reported attachment to their dog, as assessed by the Lexington Attachment to Pets Scale (LAPS). We tested specifically whether children (n = 99; mean age = 10.25 years, SD = 1.31) reported stronger attachment to dogs that were perceived as being more supportive (mea- sured by a modified version of the Network of Relationships Inventory), that were more successful in following the child's pointing gesture in a standard two-object choice test, or that solicited more petting in a sociability assess- ment. In addition, we assessed whether children's attachment security to their parent and being responsible for the care of their dog influenced re- ported attachment to the dog. Overall, perceived support provided by the dog was highly predictive of all subscales of the LAPS. The dog's success in following the child's pointing gestures and lower rates of petting during the sociability assessment were associated with higher ratings on the General Attachment subscale of the LAPS, but not on the other subscales. Caring for the dog did not predict the child's reported attachment to the dog, but did predict the dog's behavior on the point-following task and petting during the sociability task. If the child cared for the dog, the dog was more likely to be successful on the pointing task and more likely to be petted. These results indicate a dyadic relationship in which the child's care for the dog is associ- ated with the dog's behavior on the behavioral tasks, which in turn is related to the child's reported attachment to their dog. The direction of influence and nature of this dyad will be a fruitful area for future research. 相似文献

ABSTRACTThe primary objective of this program evaluation was to determine if a school-based education program is an effective means of informing elementary school-aged children enrolled in second through fourth grades about dog bite safety—the awareness of proper behavior when in the company of dogs to prevent bites, injuries, or fatalities. The pilot program, featuring written materials and a video, was developed to teach dog bite safety, and questionnaires were designed to assess the program. Students (n=486) from seven schools from Montgomery and Prince George's Counties in Maryland, USA participated. Pre- and post-program questionnaires assessed students' interactions, encounters, and relationships with dogs, as well as use of program materials, and changes in understanding about dog behavior, body language, and bite avoidance. The program results appeared to be highly effective in helping children understand how to prevent or avoid potentially threatening situations involving dogs. The program was most effective at teaching children that: (1) neighborhood and family dogs are most likely to cause dog bite-related injuries, (2) they should never run away from a dog, and (3) they should never touch a dog that is sleeping or eating. For most groups, there was also an increased level of recognition of canine body language. Almost half of the participants indicated that they had been bitten in the past, and over 80% knew the attacking dog. Finally, the findings suggest that an age-appropriate dog bite safety program delivered in an elementary school setting can be effective in producing awareness about preventing dog bite-related injuries. Future investigations should concentrate on monitoring actual changes in child behavior. 相似文献

Scientific literature exploring the value of assistance dogs to children with autism spectrum disorder (ASD) is rapidly emerging. However, there is comparably less literature reporting the effects of pet (as opposed to assistance) dogs to these children. In particular, there are no known validated scales which assess how children may alter their behaviours in the presence of the dog, to evaluate the efficacy of pet dogs to these families. Additionally, given the highly individualised nature of ASD it is likely that some children and families gain more benefits from dog ownership than others, yet no research has reported the effect of individual differences. This pilot study reports the development of a 28-item scale based on the perceived impact of a pet dog on a child with autism by parents (Lincoln Autism Pet Dog Impact Scale—LAPDIS). The scale is comprised of three mathematically derived factors: Adaptability, Social Skills and Conflict Management. We assessed how individual differences (aspects) may be associated with scores on these three factors. Family Aspects and Dog Aspects were not significantly associated with ratings on the three factors, but Child Aspects (including: contact with horses, child age, disability level and language abilities) were related to impact of the dog on all factors. Training Aspects were related to scores on Social Skills (formal training with children with ASD and dogs and attendance at PAWS workshops run by Dogs for Good). These results suggest that individual differences associated with the child and the training approach may be important considerations for a positive impact from dog ownership on families with children with ASD. Differences in family features and the dog may not be so important, but may be worthy of further investigations given the early stage of development in this field. 相似文献

In this study we sought to determine whether dog barks could be divided into subtypes based on context. We recorded barking from 10 adult dogs, Canis familiaris, of six breeds in three different test situations: (1) a disturbance situation in which a stranger rang the doorbell, (2) an isolation situation in which the dog was locked outside or in a room isolated from its owner and (3) a play situation in which either two dogs or a human and a dog played together. We analysed spectrograms of 4672 barks using macros that took 60 sequential frequency measurements and 60 sequential amplitude measurements along the length of the call. Statistical analyses revealed that barks are graded vocalizations that range from harsh, low-frequency, unmodulated calls to harmonically rich, higher-frequency, modulated calls. The harsh, low-frequency, unmodulated barks were more commonly given in the disturbance situation, and the more tonal, higher-pitch, modulated barks were more commonly given in the isolation and play situations. Disturbance barks were also longer in duration with more rapid repetition than the barks given in other contexts. Discriminant analysis revealed that dog barks can be divided into different subtypes based on context even within individual dogs, and that dogs can be identified by their bark spectrograms despite the context of the bark. 相似文献

A detector dog for screwworms (Diptera: Calliphoridae) 总被引:1,自引:0,他引:1
J B Welch 《Journal of economic entomology》1990,83(5):1932-1934
A male German wirehaired pointer, Canis familiaris L., was trained to search for and locate screwworm, Cochliomyia hominivorax (Coquerel); pupae; and animals infested with screwworms. The command, "find it" led to the detection of a screwworm-infested animal and the command "search" led to the detection of screwworm pupae. After approximately 5 mo of training, the dog could detect screwworm-infested animals. After 3 mo more of training, the dog could detect screwworm pupae. Through 7 August 1989, the dog had a success rate of 100% (265 tests) with training dummies and 94.7% (18 successes for 19 tests) with screwworm-infested animals, for an overall success rate of 99.7% (285 successes for 286 tests). Use of detector dogs at quarantine stations could result in increased efficiency, economic savings, and decreased possibility of reintroduction of screwworms into eradicated areas. 相似文献

Several factors influence how we interpret the behavior of another individual. In the current study, we investigated the effect of level of animal empathy, as well as the level of experience with dogs, on the interpretation of dog behavior. Forty-seven veterinary students participated in the study. Each student filled out a printed questionnaire on their experiences and skills with dogs, and then completed the Animal Empathy Scale. They were shown five 2-minute videos of dogs, and asked to cross off 19 visual analogue scales after each video clip, assessing 19 adjectives for each of the dogs. Principal component analysis (PCA) was performed on all of the visual analogue scale scores for each of the five videos. For every PCA, one of the components retained related to aggressiveness. For students with no prior responsibility for a dog, animal empathy score showed significant inverse correlations with the aggressiveness-component for four of the five videos watched by the students (r = –0.38, p = 0.044; r = –0.39, p = 0.039; r = –0.38, p = 0.047; r = –0.51, p = 0.005). Animal empathy did not show any significant correlation with components related to other types of emotion or behavior. There was no effect of any of the self-reported skills with dogs on the interpretation of dog behavior, and having had a dog in the family as a child only had sporadic effects. These results indicate that people with a low level of animal empathy and no prior responsibility for a dog assess dog behavior and emotion related to aggressiveness as more pronounced than people with a high level of animal empathy. The results also point to possible interactions between animal empathy, experience with dogs, and interpretation of dog behavior. 相似文献

Many studies show that people form strong affectional bonds with their dogs, treating them like family members or children. The present study investigates differences between women and men owners during interactions with their dogs, in a situation designed to investigate attachment and, thus, to promote emotional and affective responses: the Ainsworth's Strange Situation. Twenty‐five dog owners, 10 men and 15 women, were observed during free interactions with their pets in an adapted version of the ‘strange situation procedure’. Their behaviour towards their pets was videorecorded. Talking to the dog was evaluated together with the occurrence of affiliative and play behaviours. The owner's level of attachment to the dog was assessed using a questionnaire. Women and men differed in the use of verbal communication. Women talked more than men and had a shorter latency in starting talking. Their utterances resembled more closely infant‐directed speech or ‘motherese’. In contrast, there were no clear gender differences in affiliative and play behaviours. Both women and men engaged in play with their dogs and provided physical comfort. No differences emerged in the level of attachment reported by women and men owners in the questionnaire. These data support the hypothesis that the behaviour of modern pet owners towards their dogs is an interspecific parental behaviour, and suggest that behaviours evolved to provide care and comfort to human infants have been co‐opted for interacting with other social partners. The difference in verbal communication between women and men is in agreement with an evolutionary scenario suggesting a greater pre‐disposition in women to use language as a relational tool. 相似文献

ABSTRACTThis study addressed the issue of whether children who potentially have reduced access to parental resources have a stronger attachment bond with a dog, compared with children who have greater access. The study compared children in single-parent families with those in two-parent families on level of attachment to their family dog. Parents judged children's level of attachment to dogs by completing the Companion Animal Bonding Scale. The children's ages ranged between three and twelve years. Overall, children in single-parent families did show significantly higher levels of attachment to dogs than children in two-parent families. A comparison of attachment to dogs across family type showed that children in the early childhood stage in single-parent families had significantly higher levels of bonding with dogs than children in the early childhood stage in two-parent families. For the middle childhood stage there was no significant difference between family type and attachment to dogs. Comparisons within family type showed mixed results, and there were no significant gender differences in attachment levels across family type. Findings are discussed in light of attachment theory, family systems theory and implications for child development. 相似文献

ABSTRACTThis study investigated a question related to people's perceptions of dog personality. We examined whether people attribute personality characteristics to dogs based on physical features of the dog, specifically, coat color and ear shape. In order to address this question, we presented participants with photographs of dogs in which a single physical characteristic of the dog, either coat color (black vs. yellow) or ear shape (pointy ears vs. floppy ears) had been manipulated. Participants (n = 124) completed an online survey in which they rated the personality of the dogs (one black, one yellow, one with pointy ears, and one with floppy ears) while viewing these photographs. Participants rated dog personality using a brief inventory of the Big Five personality dimensions (the Ten-Item Personality Inventory). Participants rated the yellow dog significantly higher than the black dog on the personality dimensions of Agreeableness, Conscientiousness, and Emotional Stability. The floppy-eared dog was rated significantly higher than the pointyeared dog on Agreeableness and Emotional Stability and significantly lower on Extraversion. These results indicate that people attribute different personality characteristics to dogs based solely on physical characteristics of the dog. These results have implications for how people judge personality variables in dogs, particularly during brief encounters where physical attributes of the animal are likely to be highly salient. 相似文献

Given that human laughter has been posited to signal playfulness to dogs, nonserious social incongruity, and positive affect, laughter should occur during incongruous contexts in an affectively positive, nonserious social activity such as dog–human play. A total of 116 laughs in relation to dogs were discerned on videotapes of 46 dog–human play interactions in the US, 23 with familiar and 23 with unfamiliar pairs. Laughter occurred during 61% of interactions, and always expressed positive affect. Contexts in which laughter occurred (in decreasing frequency) were failure of the dog during play, or to play at all or as the person wanted; exaggerated or unexpected engagement by the dog; excretion; unexpected success by the dog in obtaining an object; and, once, threat from the dog. Laughter never induced play, and usually occurred when a dog was not playing. Women laughed more than men, especially for a male audience when playing with their own dog. In all contexts, participants experienced incongruous events; contexts were nonserious, except for the dog's threat, where laughter signaled friendliness. These data are largely consistent with laughter signaling positive affect and awareness of (usually nonserious) social incongruity, and inconsistent with laughter signaling playfulness to dogs. 相似文献

Human–dog interaction relies to a large extent on nonverbal communication, and it is therefore plausible that human sensitivity to nonverbal signals affects interactions between human and dog. Experience with dogs is also likely to influence human–dog interactions, and it has been suggested that it influences human social skills. The present study investigated possible links between human nonverbal sensitivity, experience with dogs, and the quality of human–dog interactions. Two studies are reported. In study 1, 97 veterinary students took a psychometric test assessing human nonverbal sensitivity and answered a questionnaire on their experience with dogs. The data obtained were then used to investigate the relationship between experience with dogs and sensitivity to human nonverbal communication. The results did not indicate that experience with dogs improves human nonverbal sensitivity. In study 2, 16 students with high, and 15 students with low, levels of human nonverbal sensitivity were selected. Each of the 31 students interacted once with an unknown dog in a greeting situation, and these human–dog interactions were videoed. We found that a combined score of dog behaviors relating to insecurity was associated with the students' level of nonverbal sensitivity and experience with dogs: the dog showed more of the insecure behavior when interacting with students with a low level of nonverbal sensitivity and no experience with dogs than it did when interacting with students with a high level of nonverbal sensitivity (irrespective of experience with dogs). 相似文献

Research on human–animal interaction in children has been studied in isolation rather than integrated with core theories of children’s relationships. This study is one of the first to examine how children’s relationships with pet dogs are related to their human relationships (parent–child attachments, friendships) and to child adjustment, and to include observational assessment of children’s interactions with their pet dog. Children (9 to 11 years old, n = 99) completed questionnaires regarding relationships with pet dogs, parents, and friends. Half the children were observed interacting with their pet dog. Children and teachers reported children’s adjustment. Children who felt closer to their dogs were more securely attached to mothers and fathers and reported more positive qualities and less conflict with friends. Children with more secure attachments to mothers, and greater companionship with dogs, interacted more with their dogs. Parental attachment and friendship quality, but not the pet dog relationship, were related to child adjustment. 相似文献

This study involved examining the ability of a postadoption intervention to reduce returns of newly adopted dogs to shelters by encouraging physical activity between adopters and their dogs. Guardians in the intervention group received emails with dog behavior and human activity advice as well as invitations to join weekly dog walks. Both the intervention and control groups completed surveys regarding outdoor activity with their dogs, their dog-walking habits, and perceptions of their dogs’ behaviors. Adopter–dog pairs in the intervention group were not significantly more active than those in the control group, nor did they show a reduced incidence of returning their dogs. Guardians in both groups who reported higher obligation and self-efficacy in their dog walking were more active regardless of experimental condition; however, obligation, dog-walking self-efficacy, and perceptions about their dogs’ on-leash behaviors did not predict rates of return to the shelter. These findings add to the understanding of shelter dog re-relinquishment and the effective utilization of resources postadoption, and they indicate further research is needed to address the complexities of this newly forming human–dog relationship. 相似文献

ABSTRACTThere is increasing evidence to suggest that dogs are beneficial for children with Autism Spectrum Disorder (ASD) in therapy sessions, and anecdotal reports suggest that dogs may have wider benefits, in a family setting. This study investigated the effect of dog ownership on family functioning and child anxiety. Using a validated scale of family strengths and weaknesses (Brief Version of the Family Assessment Measure-III [General Scale]), we compared parents of children with ASD who had recently acquired a pet dog (n=42, Intervention group) with a similar group of parents not acquiring a dog (n=28, Control group) at matched time points. A sub-population (n =14 acquiring a dog, n=26 controls) completed a parental-report measure of child anxiety (Spence Children's Anxiety Scale). The primary carer completed the scales via telephone at Baseline (up to 17 weeks before acquiring a dog), Post-intervention (3–10 weeks after acquisition), and Follow-up (25–40 weeks after acquisition). Over time, scores for family functioning showed significant improvements (reduced family weaknesses, increased strengths) in the dog-owning compared with the non-dog owning group. In comparison with the non-dog owning group, anxiety scores in the dog-owning group reduced by a greater percentage, most notably in the domains of Obsessive Compulsive Disorder (26% greater decrease), Panic Attack and Agoraphobia (24%), Social Phobia (22%), and Separation Anxiety (22%). The results illustrate the potential of pet dogs to improve whole family functioning and child anxiety. 相似文献

Dog bites are a human public health and dog welfare problem. This qualitative study is the first to use YouTube? to examine how viewers perceive risk of, and attribute blame for, dog bites. Comments underneath 10 videos, chosen to represent a diversity of dog-bite scenarios, were analyzed inductively using thematic analysis. Six themes emerged: 1) Commentators thought that dogs are inherently good-natured but wild animals and emphasized how dogs try to avoid biting people; 2) all recognized breeds of dogs were stereotyped and breed stereotypes were used to shift the blame away from the dog and onto a bite victim, unless the dog identified in a video was a pit bull type. The dog was often blamed in such case; 3) It was argued that a breed limits the extent to which a dog can be trained and controlled; 4) Owners/handlers were often blamed for bites due to their inability to control the dog, and commentators identified the need for appropriate training and socialization in order to control dogs and reduce bite risk; 5) Bite victims were also blamed for the bites when their behavior was perceived as provoking a dog. Although children's behavior was identified as causing a risk, parents of children bitten in the videos were blamed for bites instead due to their approach to child supervision; 6) Bites in a range of contexts, such as play or when viewers thought that the victim's behavior provoked a dog, were seen as well-de-served and normal. It was concluded that although comments on publicly available videos need to be interpreted with caution due to a self-selection bias, their analysis can help to identify attitudes and perceptions towards risk around dogs that could aid bite prevention interventions and policies. 相似文献

ABSTRACTPrevious studies conducted in the United States and Venezuela have demonstrated that people can correctly match portraits of unknown purebred dogs with their owners at statistically significant levels, suggesting that the popular belief in dog–owner physical resemblance is empirically valid. We investigated the perceived physical resemblance of dog–owner pairs in Japan, where the owners are racially more homogenous than in the countries in which the previous studies were conducted. In experiment 1, the matching performance by naïve judges was statistically significant, and a supplementary test suggested that perceived dog–owner physical resemblance plays a critical role in this. Experiment 2 presented a new procedure to test the perceived dog–owner physical resemblance and demonstrated that two-thirds of the judges selected a set of 20 real dog–owner pairs over a set of 20 fake dog–owner pairs, irrespective of whether it was an ownership-guessing task or a resemblance-based choice task. The ability to match correct dog–owner pairs (experiment 1) and the sensitivity to differentiate between real and fake dog–owner pairs (experiment 2) were not unique to the characteristics of the judges (e.g., whether or not they were dog lovers) because the task performance was independent of any measured judge-related factor. These results, taken together, provide another piece of positive evidence for the popular belief that there is a physical resemblance between dogs and their owners. Furthermore, the demonstration of dog–owner physical resemblance with racially homogeneous owner samples supports the generality and robustness of this phenomenon. The mechanism underlying this phenomenon (i.e., owners' selection of dogs that look like themselves or the convergence of appearance over time), however, remains to be elucidated by future studies. 相似文献

Hydatidosis is endemic in Neuquén, Patagonia, Argentina, even though sanitary authorities have been performing a control programme since 1970. At present, the programme is in consolidation phase, and dogs have being evaluated by arecoline purgation. The aims of this study were to evaluate diagnostic performance of a coproantigen (CAg) ELISA test developed “in house” and to assess CAg detection in prepatent period. We examined 8 dogs experimentally infected with Echinococcus granulosus and 403 rural dogs in an endemic area in Neuquén using CAg ELISA test and arecoline purgation. Within the experimental dog group, sensitivity and specificity of the test were 93.6% and 88.5% respectively. In rural dogs group, the overall prevalence of canine echinococcosis was 3.7% using arecoline purgation and 12.4% by the CAg test; sensitivity and specificity of the test using arecoline purge as standard were 73.3% and 89.9% respectively. Possible cross reactions in CAg test were evaluated in rural dogs: CAg was undetectable in 96.4% of the dogs infected only with taeniids non-E. granulosus, and in 90.1% of dogs infected with non-taeniid helminths. The CAg test could detect infections within prepatent period and produced negative results after worm expulsion. Our test showed adequate diagnostic performance with experimentally and naturally infected dogs, in the epidemiological situation of Neuquén. Employment of this sensitive and practical method for surveillance in the control programme in Neuquén would improve screening of canine echinococcosis by detecting infected dogs even with low burdens or within prepatent period. 相似文献
