Calculation of signal detection theory measures.

Signal detection theory (SDT) may be applied to any area of psychology in which two different types of stimuli must be discriminated. We describe several of these areas and the advantages that can be realized through the application of SDT. Three of the most popular tasks used to study discriminability are then discussed, together with the measures that SDT prescribes for quantifying performance in these tasks. Mathematical formulae for the measures are presented, as are methods for calculating the measures with lookup tables, computer software specifically developed for SDT applications, and general purpose computer software (including spreadsheets and statistical analysis software).

[Serotonin in arterial hypertension].

Serotonine was determined in 67 patients, 39 with arterial hypertension and 28--with normal arterial pressure. The patients are grouped into three: first group--males and females with confirmed atherosclerosis without and with systolic hypertension; the second group covers males with atherosclerosis without and with systolic hypertension and the third group --males and females with hypertonic diseases, II stage, the basic disease being complicated by atherosclerosis. The highest serotonine values were found in the patient groups without and with systolic hypertension, hypertonic disease with systolic-diastolic hypertension in males with diagnosed atherosclerosis. Serotonine impressed to be relatively lower in the females with hypertonic disease and atherosclerosis. Some humoral factors in females are presumed to be probable causes for those differences but further studies are still necessary.
