Experimental Study: Children's Perceptions Expressed Through Drawings and Coloring.

A large body of literature has addressed processes underlying human perception, with some assertions that children do not perceive space or colors in the same way as adults. Since children express themselves easily and acquire knowledge through graphic symbols, when determining psycho-motor maturity and perceptions of a preschool aged children, observers must evaluate their use of non-verbal graphics. Thus, we used young children's drawings to examine their use of color and spatial perception, as well as to identify differences between children in rural and urban communities. Of 94 participants from rural and urban communities, 46 were kindergarten aged (5.5-6.5 years), and 48 were preschool aged (4.5-5.5 years). Comparing children from urban and rural areas, there were significant differences in their perception of different colors and spatial relations. Motor abilities were significantly different between children of different ages and gender. We argue that the applied assessment methods, such as children's drawings, could be a basis for measuring effective learning and practicing of children's abilities as expressed in the classroom, and that tools may be useful for creating individualized educational plans and programs for developing children's skills through play.

Modelling driver propensity for traffic accidents: a comparison of multiple regression analysis and fuzzy approach.

This research proposes an assessment and decision support model to use when a driver should be examined about their propensity for traffic accidents, based on an estimation of the driver's psychological traits. The proposed model was tested on a sample of 305 drivers. Each participant completed four psychological tests: the Barratt Impulsiveness Scale (BIS-11), the Aggressive Driving Behaviour Questionnaire (ADBQ), the Manchester Driver Attitude Questionnaire (DAQ) and the Questionnaire for Self-assessment of Driving Ability. In addition, participants completed an extensive demographic and driving survey. Various fuzzy inference systems were tested and each was defined using the well-known Wang-Mendel method for rule-base definition based on empirical data. For this purpose, a programming code was designed and utilized. Based on the obtained results, it was determined which combination of the considered psychological tests provides the best prediction of a driver's propensity for traffic accidents. The best of the considered fuzzy inference systems might be used as a decision support tool in various situations, such as in recruitment procedures for professional drivers. The validity of the proposed fuzzy approach was confirmed as its implementation provided better results than from statistics, in this case multiple regression analysis.

The importance of spatial orientation and knowledge of traffic signs for children's traffic safety.

Pre-school children, as well as children from lower grades in primary school, who although rarely, completely independently participate in traffic, represent a vulnerable population from the standpoint of traffic safety. The greatest number of children were injured or killed in road traffic crashes on their way from home to kindergarten or school. Mostly due to lack of experience, children's behavior is confusing and often reckless and hasty. Safe behavior in the traffic environment demands certain cognitive skills. Unlike adults, children have less than fully developed peripheral vision. Also, changes occur in color perception, i.e. discrimination. All this leads to the conclusion that the stage of physical and mental development of the child is very important for safe participation in traffic. So, to estimate if they are sufficiently equipped to participate safely in traffic, a sensitive test for young children that may be suitable for their level of cognitive development is required. Accordingly, road safety education should be arranged in such a way that considers the child's level of development, as has been shown to be more effective when started at younger ages. Play is the most natural and easiest way of learning because it is the lens through which children experience their world, and the world of others. Having this in mind, if we want to measure the abilities of a child, and their preparedness for safety participation in traffic, unavoidable is to use non-verbal tests. The purpose of this study is to explore primary schooler's spatial, and abilities of color perception and memorization, as well as their performances in interpreting the meaning of traffic signs. In addition, neighborhood environmental correlates (rural-urban) and possible individual differences influences on the relationship among these abilities was examined. Knowledge about these factors affecting children's safety can be applied to improve relevant intervention measures for promoting safe participation of young children in traffic. It may constitute the basis for effective classroom work which implies the creation of individualized educational plans and programs, through which road safety skills could be acquired and adopted through play.
