This article reports interrater reliability among 4 teams of raters who independently evaluated thought disorder in 20 Rorschach protocols using the Thought Disorder Index (TDI). Intraclass correlation coefficients were calculated to assess the degree of association among the 4 teams for total thought disorder scores, severity levels, and qualitative thought disorder factors. Highly acceptable agreement was obtained. Spearman rank order correlation coefficients for these same variables were significant for all possible pairings of teams. A repeated-measures analysis of variance indicated that the absolute amount of thought disorder tagged by each team differed even though the teams' relative rankings of thought disorder among subjects was very similar. Such scoring differences reflect individual differences in threshold for detecting deviant thinking.

The buried Paleozoic bedrock surface of southern Ontario is dissected by an interconnected system of valleys. These buried valleys are infilled with thick successions of glacial, interglacial, and fluvial sediments that contain a lengthy record of changing environmental conditions during the late Quaternary. Detailed logging of over 500 m of sediment recovered from 11 continuously cored boreholes provides the basis for this study. The boreholes were drilled within two poorly defined bedrock valleys located east of the Niagara Escarpment in southern Ontario as part of a groundwater exploration program. Six distinct facies types were identified within the cores: sand, gravel, fine-grained sediment, and sand-rich, mud-rich, and clast-rich diamict. Textural characteristics of the cored sediments and vertical changes in facies types were used to identify six stratigraphic units (SU I through SU VI) within the valley-infill deposits. These units are interpreted to record fluvial or colluvial (SU I), lacustrine (SU II), fluvial, glaciofluvial or deltaic (SU III), subglacial (SU IV), glaciofluvial (SU V) and subglacial or ice marginal (SU VI) conditions. Sediment characteristics and stratigraphic relationships allow tentative correlation with known surficial deposits. Analysis of the subsurface characteristics and geometries of this stacked succession of coarse- and fine-grained stratigraphic units also allows identification of the geometry of potential aquifers.

The hypothesis that the obese are more responsive than normals to both positive and negative affective stimuli was tested in two experiments. In the first, obese and normal high school males gave ratings of positively and negatively arousing slides. In the second, the behavior of obese and normal children in a positively and a negatively arousing situation was observed. Obese subjects in both studies responded more strongly than normals to the positive affective stimuli; obese subjects in the first study responded more strongly than normals to the negative emotional stimulus. A possible reason for the failure of obese subjects in the second study to respond more strongly than normals to the negative affective stimulus was discussed.
