Beneath EEG mapping methods (e.g. Event Related Desynchronization, ERD) which focus on the level of cortical activation the coherence parameter is used to assess the level of functional coupling of brain areas. As there is strong empirical evidence that highly intelligent individuals display a more focused pattern in contrast to a more global pattern of activation during cognitive performance they should be characterized by a lower ERD as well as a lower task related coherence. In a sample of 26 males and 26 females we administered verbal, numerical and figural versions of the Posner task. Twenty-seven-channel scalp EEGs were recorded and Common Average Reference was calculated. Inter-and intrahemispheric task related coherence of EEG activity was computed. Four frequency bands were determined individually for each participant. The results show significant content-and sex related differences in both inter-and intrahemispheric task related coherence for theta and alpha bands. Generally, for all frequency bands total interhemispheric and long distance intrahemispheric coherence produced a consistent pattern of intelligence by sex interaction. While high IQ females display lower coherence as compared to low IQ females for males no significant difference was found. The results suggest sex related IQ differences in use of the brain as determined by EEG coherence.

Applications for calculating (1) distribution functions and bootstrap estimators (s. Tab. 1; c.f. Schrausser, 2023a, 2024a), (2) various parameters within the framework of psychophysiological EEG measurements (c.f. Schrausser, 2024b), (3) integral and interpolation (Schrausser, 2023b) and (4) matrix parameters (Schrausser, 2023c), s. Tab. 2. Further applications are (5) string-and number-transformation tools (Schrausser, 2023d) and finally (6) various console tools (Schrausser, 2023e), see Tab. 3.

Ptolemy's table of chord lengths from the Almagest converted into decimal values and recalculated. Presentation and discussion of Ptolemy's method of calculation and sexagesimal values in comparison to calculations by trigonometric functions with regard to several editors. A significant relationship between the difference values of the two methods and angle number was found: The higher the expansion angle, the greater the overestimation of chord lengths. Implications for early scientific astronomy in context with the development of mathematical methodology are discussed.
