Archeology in Asia during the past twenty years has taken great strides. The three main areas of new research have been in paleoanthropology, investigation of post-pleistocene neolithic sites, and ethnology. The population of Asia is now known to have been distributed over the entire mainland and Indonesia during the Paleolithic period which embraced the first million years of human evolution. There is growing evidence for the existence of many centers of plant domestication in Asia, each of which appears to have developed out of an indigenous “mesolithic” period of collecting and gathering. Recent research in linguistics and ethnology point the way to unravelling the separate histories of Asia's many cultures.

Abstract This commentary focuses on three points: the need to consider semiotic ideologies of both researchers and autistic people, questions of commensurability, and problems with “the social” as an analytical concept. It ends with a call for new research methodologies that are not deficit-based and that consider a broad range of linguistic and non-linguistic communicative practices.

Based on the conception of sensation seeking as a need rather than a temperamental trait ( Hammelstein, 2004 ), we present a new assessment method, the Need Inventory of Sensation Seeking (NISS), which is considered to assess a motivational disposition. Three studies are presented: The first examined the factorial structure and the reliability of the German versions of the NISS; the second study compared the German and the English versions of the NISS; and finally, the validity of the NISS was examined in a nonclinical study and compared to the validity of conventional methods of assessing sensation seeking (Sensation Seeking Scale – Form V; SSS-V). Compared to the SSS-V, the NISS shows better reliability and validity in addition to providing new research possibilities including application in experimental areas.

Abstract. Several decades of research are reviewed, assessing patterns of psychophysiological reactivity in anxiety patients responding to a fear/threat imagery challenge. Findings show substantive differences in these measures within principal diagnostic categories, questioning the reliability and categorical specificity of current diagnostic systems. Following a new research framework (US National Institute of Mental Health [NIMH], Research Domain Criteria [RDoC]; Cuthbert & Insel, 2013 ), dimensional patterns of physiological reactivity are explored in a large sample of anxiety and mood disorder patients. Patients’ responses (e.g., startle reflex, heart rate) during fear/threat imagery varied significantly with higher questionnaire measured “negative affect,” stress history, and overall life dysfunction – bio-marking disorder groups, independent of Diagnostic and Statistical Manuals (DSM). The review concludes with a description of new research, currently underway, exploring brain function indices (structure activation, circuit connectivity) as potential biological classifiers (collectively with the reflex physiology) of anxiety and mood pathology.
