The dopaminergic system, and in particular the dopamine D2 receptor, has been implicated in reward mechanisms in the brain. Dysfunction of the D2 dopamine receptors leads to aberrant substance-seeking behaviors (ethanol, drugs, tobacco, and food) and other related behaviors (pathological gambling, Tourette's disorder, attention-deficit/hyperactivity(More)
The entire healthy adult population of 19 nonmissionized nomadic Auca Indians of the Ecuadorian Amazon basin were given tests involving the four-colored Kohs Block Design, spatial-relational, lexical, and body and face shapes. The test results reveal a specific grouping of deficiencies in color naming (with preservation of color concept), block design(More)
Two tasks tapping various kinds of spatial-relations representation were given to test the role of spatial representation in writing and reading. (1) An intentional rotation task using six geometric (Bender-Gestalt) figures was performed by 356 children (ages 8 to 15 yr.), namely, 252 normal readers and 104 dyslexic children. (2) A draw-a-person test with(More)
The aim of the present study was to test the hypothesis that a brief clinical test of frontal lobe system (FLS) maturity levels, designated as Stages I, II, III, IV, can differentiate between three experimental groups (all of age 9-16): normal Ss, Ss with emotional problems, and juvenile delinquents. The stages represent 1) disjointedness of activities; 2)(More)
A neuropsychiatric and -psychological update of the crime "profile" and "signature" is a necessary addition to the traditional sociopsychological model likely to miss limbic system dysfunctioning. Thus, occurrence of a brief (c. 20 minutes) limbic seizure has been proposed based on behaviors of 12 white male homicidal loners, who showed a dozen symptoms and(More)
A novel test, Draw-A-Person-With-Face-In-Front, uses simple measurement with a ruler to detect subtle misrepresentation of spatial relations within the pattern of the human face (in contradistinction to facial recognition tests). Studies have repeatedly shown a close association between misrepresentation of the face and low or absent skills in widely(More)
