Fight Or Flight Response

A rank-order correlation was performed for nine cultural groups ranging from preliterate hunter-gatherers to literate medium-city dwellers. Two spatial tests of intrapattern spatial relations were used, the Draw-A-Person-With-Face-In-Front test and the Kohs Block Design, a test of constructive praxia. In contrast to traditional “Western” evaluations, credit was given for the preservation of the essential intrapattern shapes even when exact spatial relations among these shapes was incorrect. Such “errors” were labelled “neolithic face” patterns and “nonrandom errors,” respectively. Analysis suggested that the neglected intrapattern (in contrast to interobject) spatial relational skills emerge with literacy but is not yet actualized in preliterates whose survival requires quick fight or flight response upon prompt, albeit gross, assessment of salient shapes of prey or predators (human or animals). The positive Spearman rank-order correlarion of absent or low literacy skills with the percent of “neolithic face” drawings was .95 and with the “nonrandom” block designs .67. Suggestions were developed for assessing certain unusual “ecological” present situations or certain brain dysfunctions.

Main Factor

A new model posits that there are specific patterns of groupings of several delayed human cognitive functions or dysfunctions in certain ecological circumstances which characterize a significant portion of a cultural group. It is further posited that such patterns (“ecological syndromes”) are primarily based on as yet unknown neurophysiological givens. This deduction is based on the occurrence of several specific groupings of delayed cognitive functions or dysfunctions that have been identified in diverse time periods and cultural groups where no brain pathology can reasonably be expected. The “ecological syndromes” were, however, noted to be analogous to those found in neuropathology. The main factor contributing to such an “ecological syndrome” appears to be a specifically limited under-use of certain functions not needed for the survival of certain populations without implying any general cultural deprivation. Some examples of “ecological syndromes” are mentioned: low arithmetic skills linked with quantitatively inaccurate pictorial (and implied mental) representation of fingers, low literacy skills linked with specifically inaccurate pictorial (and implied mental) representation of the subtle spatial relations of the configuration of the human face, and an “ecological apractognosia” observed among wigmen of New Guinea.

Cultural Evolutionary

A new model posits the existence of a general link between ecological (cultural) factors and post-natally evolving cognitive functions and in particular the emergence of such functions in specific clusters. Such “ecological syndromes” are characteristic of a significant portion of a cultural group and analogous to syndromes found with certain brain lesions without implying them. Presently a specific link is noted between known low skills in arithmetic and as tested here, quantitatively inaccurate pictorial (and implied mental) representation of fingers in 78% of New Guineans and 70% of Indonesians living in remote areas, while only 16% of Western European regular school children (ages 7 to 10 yr.) misrepresented the fingers in drawing a person. Previously a link between low literacy skills and inaccurate spatial relations in representing the pattern of the face was found for diverse time periods and cultural groups.

Similarity Judgments

Reverse strategies are used in judgments of similarity by hunter-gatherers who prefer using shapes (attributes) in patterns, and literates who prefer judging relations among shapes The Kohs Block Design Test was given to healthy hunter-gatherers, 19 stone-age, preliterate, Amazonian Auca Indians and 130 semi-literate Dani and Asmat of inland Indonesian Western New Guinea. Further, 196 literate Indonesian city dwellers served as controls. The Auca and the Dani and Asmat groups preferentially constructed 20 specific, “nonrandom” modifications similar to the Kohs Block Design Test and preserved the salient component shapes but neglected relations among them. Hunter-gatherers' survival depends on prompt assessment of the salient shapes of prey and attackers. By contrast, literacy skills require painstaking assessment of subtle intrapattern spatial relations among shapes.

Pictorial Representations

A specific link is found between low of absent literacy skills and a specific misrepresentation of spatial relations exclusively of the upper part of the human face. This misrepresentation, determined by simple measurement, is found in 32% of the pictorial representations of 407 preschoolers whose drawings were published by various authors as well as in 32% of 44 preschoolers tested here. By contrast, after having had instruction in literacy, the proportion of such misrepresentations of the face drops to 7.5% and 10%, respectively, although, as expected, not in the drawings by 236 mildly mentally retarded or by 297 dyslexic children, 33% and 39% of whom, respectively, still misrepresent the face. In addition to a developmental factor, a further one, as yet undetermined, may be at work and related to a specific deficit in representing the spatial relations of the face. Data further support the previously suggested existence of a specific and general trend for a link between literacy skills and accurate representation of the spatial relations of the pattern of the face also noted previously in diverse cultural groups and periods.

Dyslexia Subtype with Simultaneous Processing of Intraobject Spatial Relations in an “Ecological Syndrome”

Visuospatial Representation

Three interrelated phenomena of a global visuospatial representation are discussed within the context of a subtype of “spatial dyslexia” as part of an “ecological syndrome.” (1) Results from a new test, Draw-A-Person-With-Face-In-Front (using simple measurement and requiring no graphic or aesthetic skills) showed in a third of 269 Australian Aboriginal school children a deficient representation of spatial relations within the natural pattern of the upper part of the human face. (2) The test performance apparently is an indicator of a similarly deficient representation of the spatial relations within written signs (single letters, short, isolated functional words, and novel or “nonwords” lacking strong semantic association and imageability). The test discriminates between two modes of visuospatial pictorial (and implied mental) representation, a simultaneous and merely “ inter object”-related global kind vs a successive and “ intraobject”-related one. Further support for such conceptualizing is found in a positive correlation between certain low literacy skills and the specific results (in 6000 examined cases) on the new drawing test. Both inabilities implicate a simultaneous global mode of visuospatial processing, which early in life promptly elicits the infants' in discriminate automatic “smiling response” and appears to be resorted to still later in life by persons with “spatial dyslexia.” (3) Such conceptualizing interrelates with the so far puzzling difference between “literal alexia” vs “verbal alexia” known to neuropathology (not implicated in the present cases but pointing to an underlying structuring process shared by pathological and by “ecological syndromes” alike).

Abstract People who plan ahead typically fare better during the response and recovery phases of a disaster. However, problems arise when the needs, wants, abilities, and resources of vulnerable people are not adequately considered. The lack of alignment between the literacy demands of existing materials and the literacy skills of many vulnerable subgroups limits their ability to understand and effectively use potentially life-saving information. Existing health literacy models that have demonstrated effectiveness in changing health behaviors and improving outcomes is a first step to reducing disaster-related morbidity and mortality in low resource and low literacy areas. This presentation will 1) describe how interdisciplinary collaborations can be used to address this public health issue, 2) explain how health literacy techniques can be applied when developing disaster materials, and 3) present research data on a social marketing campaign to improved disaster preparedness of older adults.

Neighbor Discovery Protocol

Neighbor discovery is a significant research topic in wireless sensor networks. After wireless sensor devices are deployed in specific areas, they attempt to determine neighbors within their communication range. This paper proposes a new Block design-based Asynchronous Neighbor Discovery protocol for sensor networks calledBAND. We borrow the concept of combinatorial block designs for neighbor discovery. First, we summarize a practical challenge and difficulty of using the original block designs. To address this challenge, we create a new block generation technique for neighbor discovery schedules and provide a mathematical proof of the proposed concept. A key aspect of the proposed protocol is that it combines two block designs in order to construct a new block for neighbor discovery. We analyze the worst-case neighbor discovery latency numerically between our protocol and some well-known protocols in the literature. Our protocol reveals that the worst-case latency is much lower than others. Finally, we evaluate the performance ofBANDand existing representative protocols through the simulation study. The results of our simulation study show that the average and maximum latency ofBANDis about 40% lower than that of existing protocols. Furthermore,BANDspends approximately 30% less energy than others during the neighbor discovery process.
