This paper describes a hitherto unidentified adaptation in Grooved Ware pottery at the Ness of Brodgar, Orkney ( Fig. 1 ). The technological technique adopted appears designed to cope with a common problem of Grooved Ware potters at the Ness: that of detached cordons, where applied decorative cordons on the exterior surface of the vessels are knocked off or simply fall off. The evidence shows that, in the case of one large pottery deposit from the site, some vessel exteriors were specially prepared in order to ensure cordon adhesion. The Ness of Brodgar site is introduced, issues surrounding pottery production and applied decoration in the Late Neolithic, particularly in Orkney, are noted and the problem-solving sherds are described. The paper is illustrated in part by the use of Reflectance Transformation Imaging (RTI).

Reflectance Transformation Imaging

Newly discovered and previously documented Late Neolithic chalk plaques from the Stonehenge locality have been subjected to new, non-invasive techniques which allow access to previously unseen elements of archaeological evidence. The application of these methods – involving Reflectance Transformation Imaging (RTI) and Polynomial Texture Mapping (PTM) – has revealed detail of the surface preparation and allowed methods and sequence of the compositions to be unpicked, clarifying their complexities. The results reveal a range of approaches to the compositions, some of which demonstrate planning, order, and intention while others include less systematic, rapidly executed sketches. Investigations of lines and surfaces have been made, supplemented by preliminary studies of replicated test pieces, to examine potential implements used in their creation and remark on plaque biographies and surface attrition following manufacture. Furthermore, detail revealed by RTI provides indications of the orientations in which some of the plaques should be viewed and – in one instance – suggests a ‘reflected’ element that may not be entirely abstract. Results from improved radiocarbon determinations place the plaques in the early part of the 3rd millennium bc which, together with identification of individual motifs, allows the plaques and the designs to be reconsidered within the corpus of Neolithic art in the British Isles.

Reflectance Transformation Imaging

Latvia in the 11th–13th century poses a curious case for the coexistence of two different practices of Baltic ware production. The Baltic ware pots from lower reaches of the River Daugava and from the Courland region look not just stylistically, but also technologically different. Our paper assessed the production traces by using macro-observations, Reflectance Transformation Imaging (RTI) and extensive ethnographic material of Slavic pottery production of the 1900s, as well as using modern replicas as visual aids to assist in the identification of the principal coil attachment methods. The results showed that potters from the lower reaches of Daugava used the wheel’s rotation extensively during the shaping process of Baltic ware. The production of the pots required the potter to possess a level of technical skill which implied a level of professionalisation. Baltic ware from Courland was less technically complicated and used comparatively more of the methods of handmade pottery production.

Speech Model

The paper explores the processes by which children use private speech to regulate their behaviors. The first part of the paper explores the ontological development of self-regulating private speech. The theories of Vygotsky and Luria are used to explain this development. The second part of the paper applies these theories to pedagogical settings. The process by which children are exposed to dialogue strategies that help them solve problems is outlined. The strategy has children posing and answering four questions: What is the problem? How will I solve it? Am I using the plan? How did it work? It is argued that this model helps children systematically mediate their problem solving processes.
