瑞文推理测验上的性别差异

瑞文推理测验上是否存在性别差异？与较早期的研究结果不同, 较近的一系列研究发现在瑞文推理测验上存在性别差异, 且性别差异具有发展性。当前可以解释该性别差异的观点主要有两种, 其一是污染观, 即认为瑞文推理测验中发现的性别差异实质上是由于测验中其他成分的“污染”所致, 而在它所主要代表的g因素的发展中并不存在性别差异; 其二, 较新的研究提示, “污染”可能存在, 但在g因素上仍然具有性别差异, 这种差异是由生理上的原因造成的。研究者由此提出了智力性别差异的发展理论。本文主要从儿童青少年发展的角度回顾了有关瑞文推理测验性别差异的研究, 综述并分析了关于性别差异研究结果不一致的可能原因。     

Migratory selection for inversely related covariant T-, and IQ-Nexus traits: Testing the IQ/T-Geo-Climatic-Origin theory by the General Trait Covariance model

The IQ/T-Geo-Climatic Origin (GCO) theory admits that primordial northbound migration out of Africa increasingly demanded higher IQ and decreased aggression as temperatures sank. To organisms with a fixed intra-systemic energy budget, this meant that small-brained – High T (Lo-IQ/Hi-T)” masculine aggressive A5 males became too “expensive” in cold eco-niches, and were replaced by Low Testosterone androgyne A1 (Hi-IQ/Lo-T) light-weight males with sufficient energy for developing the large energy-greedy brain needed for survival during cold winters. The physiological re-balancing of T-Nexus and IQ-Nexus traits probably occurred during migration over the past 40,000 years.     

Personality,age, and fluid intelligence

A total of 383 participants (aged 19 to 66 years) completed the Raven's Progressive Matrices, the Myers‐Briggs Type Indicator (MBTI), the Fundamental Interpersonal Relations Orientation‐Behavior (FIRO‐B), and the California Psychological Inventory‐434 (CPI‐434). Results showed that IQ was positively correlated with perceiving (MBTI), control (FIRO‐B), intellectual efficiency (CPI‐434), achievement via independence (CPI‐434), and negatively correlated with sensing (MBTI), internality (CPI‐434) and norm‐favouring (CPI‐434), supporting the majority of the hypotheses. Participants' age was correlated with many measures, particularly intelligence and accounted for a third of the variance in IQ scores. Limitations are considered.     

Transfer in discrimination learning: Do children mediate more than adults?

A series of four-dimensional, discrimination-learning problems were presented to second-, sixth-, eighth-, and twelfth-grade students (ages 7, 11, 13, and 17 years, respectively). One pretraining problem, using different dimensions, preceded the four experimental problems; these employed identical dimensions and stimulus values. Solutions were selected without dimensional replacement.Blank-trial probes enabled detection of initial predictions. Results clearly indicated that (1) older subjects made dramatically fewer intradimensional predictions (utilizing the solution dimension from the preceding problem) than did younger subjects, (2) all age groups demonstrated systematic changes over problems; these reflected the specific solution sequence experienced, and (3) there were consistent developmental differences in the speed with which subjects noted and utilized regularities across problems.The pattern of data is not congruent with the expectations of mediation theory. However, it is in accord with the transfer hypothesis, which is a recent extension of hypothesis theory. The transfer hypothesis provides a theoretical framework which suggests when we should observe “mediational” behavior (i.e., intradimensional transfer) and when to expect the inverse.     

On the validity of Raven’s matrices test: Does spatial ability contribute to performance?

The paper reports on an investigation of the convergent and discriminant validity of Raven’s matrices in considering reasoning and spatial abilities. Raven’s advanced progressive matrices (APM) and four scales representing reasoning, visualization, mental rotation and closure were applied to a sample of N = 280 university students. The data were investigated by means of structural equation modeling. The results demonstrated convergent validity of APM with respect to reasoning. In contrast, in investigating discriminant validity substantial correlations of moderate size between APM and the scales representing spatial abilities were observed. However, the investigation of the structure of the prediction of APM revealed that the scales representing spatial abilities did not improve the prediction based on the reasoning scale alone at the latent level. Consequently, it is suggested that Raven’s matrices show good convergent validity and slightly impaired discriminant validity.     

Normative data for the Boston Naming Test in native Dutch-speaking Belgian children and the relation with intelligence

This paper reports the results of a normative study of the 60-item version of the Boston Naming Test (BNT) in a group of 371 native Dutch-speaking Flemish children between the ages of 6 and 12 years. Analysis of test results revealed that BNT performance was significantly affected by age and gender. The gathered norms were shown to be significantly lower than published norms for comparable North-American children. Error analysis disclosed remarkable similarities with data from elderly subjects, with verbal semantic paraphasias and 'don't know' responses occurring most frequently. Finally, BNT scores were shown to correlate strongly with general intelligence as measured with the Raven Progressive Matrices. The relation between both measures can be of help in the diagnosis of identification naming deficits and impaired word-retrieval capacities.     

Cross-generational acceptance of and interest in advanced vehicle technologies: A nationwide survey

The number of older drivers on the roadways is increasing; at the same time, technology in the automotive environment is rapidly evolving. To investigate the potential impact of these converging changes, this study used a cross-generational approach to compare driver attitudes toward advanced automotive technologies. Approximately 1000 drivers between the ages of 18 and 85 located across the United States responded to a survey about their opinions regarding general technology, advanced in-vehicle technology, and near-horizon connected vehicle systems. Participant responses were categorized using a generational construct, sorting responses not only by age but by shared life experiences (e.g. economic circumstances, involvement in wartime activities, cultural movements, etc.). The oldest generation (the “Silent” generation) exhibited the least interest in and comfort with advanced technology, although they owned and used advanced in-vehicle technology at approximately the same rates as the two middle generations. The youngest generation (the “Millennial” generation) was most likely to be interested in and comfortable with technology, but was least likely to own vehicles with advanced technology. All participants expressed interest in safety-related connected vehicle systems, but less so in infotainment applications. Reservations regarding data security and system cost were shared across generations. These findings are framed in the context of an aging population with unique driving and vehicle needs, and provide information that may assist both with vehicle technology design aspects and the proposed large-scale implementation of connected vehicle systems, including considerations for seniors and emphasis on safety systems and data security.     

Using an integrated simulation environment for the risk based design of advanced driver assistance systems

When designing new Advanced Driver Assistance Systems (ADAS), the existing guidelines like the RESPONSE 3 Code of Practice imply intense testing of the system prior series production. Within the EU-FP7-Project ISi-PADAS a new methodology of risk based design has been established which includes an integrated simulation platform. This integration enables intense testing of new prototypes in an accelerated way and therefore enhances the design process while directly combining the simulation results with a risk matrix.This paper describes the new methodology while focussing on the software framework and the procedure of risk assessment in detail. It shows the general approach as well as the appropriate steps taken for an ADAS prototype developed in the context of ISi-PADAS.
