'Figure it out!' Psychological Perspectives on Perception of Migration Period Animal Art

In this article we explore some perceptual-psychological and semiotic aspects of the Migration Period 'animal art'from the northern Germanic cultural area. Primarily, it is suggested that this art, which has been described as using symmetry and 'split representations', is laden with 'ambiguous figures' (including 'embedded figures' and 'reversible figures'). The ambiguous quality of the art is suggested to be presenton a perceptual level, but also on a compositional (structural) and iconographic level. Psychological (and neurological) processes involved in the perception of ambiguous figures and their effects are presented: Gestalt formation, unconscious processing, subliminal perception, motivated perception, and changed states of consciousness. It is suggested that this art instigated,or at least referred to such processes. In addit ion,on a semiot iclevel, t heart is suggested to contain information-condensation ('hyper-texts'), cryptic information, and to have had other semiotic functions.     

Early Port-Related Structure Studies

This paper examines three of Australia’s earliest port-related structure studies. Excavations conducted in 1984 and 1994 in vastly different circumstances, with markedly different oceanographic conditions, progressing through quite different substrates, were joined with 1993–1994 overview of all the port structures along the coast of Western Australia. Providing a better appreciation of submerged port-related structure studies as a bona fide part of maritime archaeology, these three studies and have ramifications for future work both in Australia and overseas.     

Bromine in teeth and bone as an indicator of marine diet

Nitrogen isotope ratios in tissues are often used to aid in the reconstruction of the marine component of diets in past populations. Elevated δ¹⁵N values normally found with high trophic level marine resource consumption can, however, also be mimicked by physiological conditions (breastfeeding, pathological states affecting nitrogen balance), climate (aridity), and anthropogenic environments (manuring). This paper presents a pilot study testing whether bromine concentrations can provide a tool for teasing apart possible causes of variation in nitrogen isotope ratios. Blind analyses of bromine in archaeological samples correctly identified individuals derived from coastal vs. inland regions and high vs. low marine consumption time periods. Thus, bromine can provide an important supplement to other isotopic analyses of diet.
