Due to the last two decades of escalated technical development IQ researchers nowadays have to integrate some new pieces of empirical evidence coming from neuroscience. At the beginning of the 21st century the research of the neural background of intelligence arrived to a new chapter owing to the simple availability of functional imaging techniques, like fMRI and other neuro-physiological methods (e.g. EEG). To extend our results and to move on we need to clarify the relationship of data and organize our knowledge. In this review we summarize results on the neural background of intelligence that derive from clinical or normal, child or adult samples. The data suggest that intelligence is supported by a distributed integrated neural network.

The paper explores why certain adults are, or at least consider themselves to be, more ironic than others. The study looked at comprehension and application of irony compared to subjective affective evaluation of irony reported by Polish-speaking adults and with relation to nonverbal intelligence measured with the Wechsler Adult Intelligence Scale-Revised-Polish versions (WAIS-R(PL), 2004). Fifty-four subjects aged 20-66 years (28 females and 26 males) participated in Study 1 on subjective perception of irony. The comprehension, emotional valence and social functions of ironic meanings as well as the degree to which subjects perceived themselves as ironic were assessed through a self-report questionnaire. Inter-correlations were performed and related to the performance quotient (IQ) which was measured in Study 2, where 45 (24 females and 21 males) out of the 54 participants were tested with performance subtests of the Wechsler Adult Intelligence Scale-Revised-Polish versions (WAIS-R(PL), 2004). The nonverbal intelligence scale was administered. Performance on nonverbal intelligence tests is not limited by language abilities and its analysis and can be considered important for future cultural comparative studies. Subjects who perceived themselves as ironic showed a higher nonverbal IQ in comparison to subjects who described themselves as non-ironic or barely ironic. The pragmatic qualities of irony were analyzed for their affective valuation and balanced for gender. Individual differences and gender effects in the perception of the social functions of ironic utterances were found. The paper describes the implicit emotional layer conveyed in irony and its importance in irony processing and comprehension.

The paper presents propositions of modification in correlation and regression linear analysis. It is a result of problems in interpretation of statistical dependance measures in case where data are referring to aggregate units (e.g. countries). The paper shows results of research made at the beginning of 2000 for 81 countries by R. Lynn and T. Vanhanen who show that IQ is one of important factors contributing to differences in wealth of nations and rates of economic growth
