Do As I Do: Copy Cat Social Imitation in Dog Training

by Cobb & Hecht in Do You Believe In Dog?

Join us for another guest post, this time from Claudia Fugazza of the Family Dog Project in Budapest. Claudia's here to discuss her recent publication in Applied Animal Behaviour Science on the efficiency of new methods in dog training.Hi Mia and Julie,Formal training methods used until now rely mainly on the well-known rules of individual associative learning. These methods work perfectly well for a very wide range of animals — pigeons, rats, dogs and even crabs — and human and non-human animals can learn by ‘click and treat,’ as noted in the popular training book by Karen Pryor. However, recent research has found substantial evidence that dogs could be predisposed to acquire information socially via the ‘Do as I do’ method. Do as I Do is a relatively new training method for people to use, based on dogs’ social cognitive skills, particularly on their imitative ability.  With this training technique, dogs learn new behaviors by observing and copying their handler. The dog is a copycat. This method relies on social learning, and it was recently introduced in the applied field of dog training.  As this method has started spreading in the dog training world, we felt that its efficiency and efficacy needed scientific testing. We were also wanting to know whether this method would be more or less efficient than other current training methods in training for particular behaviors.We expected that dogs would more easily copy object-related actions from a human demonstrator so we tested dogs’ efficiency in this kind of tasks. To do this, I travelled across Italy and the UK with my video-cameras as well as a heavy Ikea cabinet filled with objects (you can imagine the weird looks I got from security personal at checkpoints!). I used these objects to test dogs learning to open or close drawers and lockers, pick up items from it etc. Since training methods can be affected by the skills of the trainer, only experienced dog-owners pairs who achieved a certificate either for the ‘Do as I do’ method or for shaping / clicker training were included in the study. Each pair was tested using ‘his’ method for teaching three different object-related actions in three testing sessions. We expected that the ‘Do as I do’ method would prove more efficient for teaching complex tasks, compared to the shaping method that relies on individual learning. This expectation comes from what we know in humans: we tend to rely more on social learning when required to learn something difficult.Our research found that the ‘Do as I do’ method proved more efficient for teaching dogs complex tasks, like close a drawer, open a locker and pick up an item that was inside (i.e., the time needed by the owner to obtain the first correct performance of the predetermined action was shorter with the ‘Do as I do’ method compared to shaping). We did not find a significant difference in the efficiency of the methods for teaching dogs simple tasks like knocking over a bottle or ringing a bell.Now that we know a bit more on how to efficiently teach complex object-related actions, we are curious to know what happens when we want to teach different kind of complex actions, like body movements. We also want to know whether introducing social learning in dog training could have an effect on learning cues for trained action. We are aware that learning rates can be influenced by many factors, and we acknowledge that this study is just a very first step towards a more scientific approach to training paradigms. However we believe that this kind of information can be very important for the practitioners working in the applied field of dog training. We hope that the readers will not misinterpret the results and will not extend them to different actions and situations that were not tested.Furthermore we would like to emphasize that, despite being efficient for training some kinds of actions, the ‘Do as I do’ method does not replace the methods based on individual learning (for example think of how many actions are not imitable at all if the demonstrator is a human and the learner is a dog!). Instead ‘Do as I do’ is a useful (and fun!) addition to existing training paradigms. Experienced dog trainers may find effective ways to mix the different training techniques in order to obtain the best results with each dog.  Claudia FugazzaDo as I Do Book and DVDhttp://www.apprendimentosociale.it/en/claudia-fugazza/Family...

“I am Working-Class”: Self-Identification as a Measure of Social Class in Educational Research

by Mark Rubin in Mark Rubin's Social Psychology Research Blog

Governments around the world are trying to open up higher education to working-class people. For example, in January this year, the White House released a report titled: "Increasing college opportunity for low-income students: Promising models and a call to action." In the context of this general push towards widening participation in higher education, my colleagues and I have been developing a research project that aims to investigate social class differences in social integration among students atuniversity. After all, we need to bring working-class people into our universities socially and psychologically as well as physically. As we developed our research project, we quickly realised that the measurement of social class is an extremely contentious issue, with different researchers often preferring different measures. In particular, we noticed that there was a clear divergence between social psychologists and educational researchers in the types of social class measures that they used. Following the recommendations of a 2006 American Psychological Association report on measuring social class, modern-day social psychologists use subjective, self-identification measures of social class alongside more objective measures of income, occupation, and education (for a good example, see Michael Kraus’work). In contrast, educational researchers have tended to restrict themselves to objective measures and to ignore the more subjective aspects of social class (for a recent review, see Rubin, 2012; for a notable exception, see Ostrove & Long, 2007). We have discussed this interdisciplinary discrepancy in a recent review article published online this month in Educational Researcher. In our article, we call for educational researchers to follow the lead of social psychologists and complement (not replace) their objective measures of social class with measures of subjective social class. We believe that subjective measures are not only valid and reliable but also more direct and sensitive in their assessment of social class compared with objective measures. Most importantly, subjective measures tap the social identity aspect of social class, and they give a voice to students’ own opinions about their social class.

Oral Health Status among 12 Year Old Children in a Rural Kenyan Community

by JDOH in JScholar Publishers

Dental caries remains a common disease among school-aged children and is thought to be increasing worldwide, especially in developing countries. The Oral Health Country/Area Profile Project reported that the Decayed, Missing and Filled Teeth (DMFT) index, a standard indicator of oral health, increased steadily from 1.15 in 2004 to 1.19 in 2011 in 12-year-old children living in African countries [1]. In contrast, a systematic review of information published from 1967 to 1997 concluded that the DMFT index among 11–13-year-old in Sub-Saharan Africa had not increased significantly during this earlier time period [2,3]. However, assessing long-term trends in the incidence of dental caries is difficult due to the lack of nationwide survey data in most African countries. Several studies have examined oral health status among schoolchildren in Kenya, but they have mainly been conducted in urban areas and cross sectional in nature. Accordingly, neither the current oral health status nor changes over time is adequately documented in rural Kenyan schoolchildren.
