Experimental archaeology has grown beyond replicating craft and technology and is now exploring the nature of skill acquisition and learning processes. Questions such as to how people learned skills in the past and how that knowledge was transmitted/communicated, provide new areas in which experimental archaeology can produce essential data. The latest research on this subject is presented  in the November issue of the Cambridge Archaeological Journal, which explores these facets and opens up new areas of enquiry.

The first article, “Skill Learning and Human Brain Evolution: An Experimental Approach” by Dietrich Stout and Nada Khreisheh, provides an overview of recent studies in experimental archaeology directed at trying to understand how flint knapping is learned. Their study employs a methodology that includes psychology and neuroscience to record the learning process. Using fMRI (Functional magnetic resonance imaging), parts  of the brain are examined for changes in blood circulation that indicate areas of neural activation. In other words, by recording brain activity whilst  learning knapping skills, the engaged areas of the brain can be located, which in turn might be associated with other acquired skills. For example, it was noted  that the prefrontal cortex of the brain was engaged whilst  knapping. This is an area associated with higher order cognitive action, which might also be linked to language processing (Vigneau et al. 2011).

The article critically examines earlier studies which utilise  experimental archaeology to examine skill learning andsummarises these by, recording the length of time it took to learn the skills necessary to successfully reproduce Palaeolithic hand axes. These studies included both verbal instructions (Morgan et al. 2015) and non-verbal instructions (Putt et al. 2014). In addition the authors describe an interesting study carried out by Hecht et al.(2014), which showed how areas of the brain were active and then faded when skills were not frequently practiced. The authors recognise that longer term studies are needed and that this area of research has a rich potential for further work. While this article  focusses on the use of technology to record skill learning, it also  shows how experimental archaeology has become an essential part of research.

Two other articles, one by April Nowell and another by Francesco d’Errico and William E. Banks are part of the  special section; teaching and learning. While these are not specifically based on experimental archaeology, as seen in the article above, understanding the learning process can be a significant part of experimental archaeology. As experimental archaeologists we are not only recreating the tasks, but we are actively engaged in learning techniques that may have been lost, or are at least not commonly learned in modernsocieties. While we seek to replicate the technology and techniques used to create accurate reproductions of artefacts, we cannot replicate the exact conditions or environment in which they were created. For this reason the archaeology of learning can provide essential insights into the processes by which early humans, and even those who lived in later prehistory, learned technological processes and passed that knowledge on to others.

Nowell’s article concerns the Upper Palaeolithic children of Southwest France and Northern Spain, incorporating the pictorial culture of the period. In addition to the more familiar cave paintings there are thousands of carved objects, rock carvings, and alsobody art in the form of  tattoos and body paint (White 2007). There is also evidence for weaving and textile art (Kvavadze et al. 2009; Sofer 2004; Sofer et al. 2000).

Examination of paintings and hand prints in caves indicate that children participated in producing art along with adults. Nowell explores how imagery is used to transform the world and how children learn to recognise two-dimensional designs and to understand them as representations of three-dimensional objects. The fourth-dimension is also explored in the form of objects that move or have the semblance of motion. Examples of the latter form of  art come in the form of images animated by flickering fire to optical toys known as rondels or thaumatropes. These are perforated discs with an image on either side. When suspended on strings and pulled rapidly, the images create the semblance of motion. One example given shows a deer-like animal that appears to jump(Azèma and Riviére 2012, 322). Understanding the learning and recognition process of two- and three-dimensional representations helps us understand how early humans were able to hold an image in the mind while creating objects, resulting in new ways of seeing and interacting with the world.

The “Archaeology of Teaching: A conceptual framework” looks at the origins of cultural transmission and how to recognise it in the archaeological record. Francesco D’Errico and William Banks break down the learning process into a framework of spatial, temporal and social dimensions. For example the spatial category consists of eight elements, the first of which is learning from a distance, whereby  the learning process occurs when observed from a distance far enough removed that the practitioner is not aware of being observed. The steps proceeding describe  the proximity along with  the increased interaction of the participants in the teaching/learning process. The final element consists of an explanation in the absence of direct observation of action, in which the teaching is not transmitted directly, but instead is given in a coded form, such as writing or mathematics. The temporal dimension acknowledges that learning takes time and follows a similar process to the spatial dimension, in which teaching is done in increasingly larger sequences until finally the process is also delivered in a coded form. The final dimension is social, in which the first level of learning and teaching takes place between those of the same generation and becomes more complex as the relationship spans generations.In the article the authors include the  knapping strategy of the Oldowan stone tool industry, the manufacture of horn cores, the use of bone fragments as digging tools and the application of Aurignacian and early Upper Palaeolithic personal ornaments as case studies.

Using the systematic template  created for the learning processes, the examples utilised can be fitted into the categories of spatial, temporal and social dimensions. Therefore,  stone tool making could be learned by observation, but was more likely to be learned through gesture moulding whereby  the teacher guides the hands of the one learning, or by having details of the actions  described verbally.The framework could be applied to studies such as those carried out by Tostevin (2012), where  he explored the process of learning flint knapping through experiment and reconstruction of debitage.

The authors invite others to apply  the framework that they developed for learning dimensions.. Here experimental archaeology could benefit from the systematic observations of the teaching/learning process. Could a skill be learned from observing from a distance, or even close-up but without verbal guidance? Such exercises could enhance the experimental process and add to the subject of how knowledge could have been transmitted.

This issue also contains reviews of recent publications on material culture theory and other articles about early lithic technology, along with learning theory.
