Effects of tobacco smoking on electroencephalographic, auditory evoked and event related potentials

After overnight abstinence, tobacco smokers smoked an average nicotine yield cigarette and nonsmokers sham smoked an unlit placebo cigarette. EEG alpha(1), delta, and theta frequency amplitudes decreased, whereas alpha(2) and beta frequency amplitude increased. Short, middle (EP) and long latency ERP were also studied in nonsmokers and smokers just after smoking, and after overnight abstinence from tobacco. Short latency potentials were unaffected by tobacco smoking or abstinence. Middle and long-latency potentials were reduced during abstinence and enhanced immediately after tobacco smoking. These findings indicate that compared to nonsmokers smokers have a higher arousal level after smoking than when partially abstinent. Evidence for both normalization from tobacco abstinence as well as stimulation was obtained.     

Synesthesia and creativity in fine arts students: An Empirical Look

Abstract:

A survey of 358 fine arts students at three large universities indicated that 23% (84) experienced synesthesia in a spontaneous and consistent manner, and 49% (175) reported no such experience. From this subject pool, 61 synesthetes and 61 controls, equated on gender, major, year in school, and verbal intelligence, received a battery of four creativity measures. The synesthetes scored significantly higher than controls on all four creativity measures; and their self‐rated frequency and vividness of synesthesia though significantly intercorrelated, correlated marginally with the measures of creativity. The results are consistent with anecdotal reports that synesthetes are often involved in musical and artistic fields, and possessive of a high degree of creativity.     

Assessment of creativity with the ACL: An empirical comparison of four scales

Several scales have been developed from the Adjective Check List to assess creativity, with almost no comparative data to evaluate them. In this study, two samples, one of research scientists and one of advanced architecture students, were assessed using the A CL scored for the Domino, Gough, Schaefer, and Yarnell scales of creativity. The results indicated a fair amount of equivalence among the four scales, with a tendency for the Domino and the Gough scales to have better convergent and discriminant validity.     

A personality measure of Erikson's life stages: the Inventory of Psychosocial Balance

The development and initial validation of the Inventory of Psychosocial Balance (IPB), designed to assess all eight Eriksonian psychosocial stages, is described. A pool of 208 items that survived a clinical analysis was administered to 528 subjects and then factor analyzed. The resulting eight factors parallel the eight stages and account for 72.34% of the total variance. Subsequent administrations of the IPB to various samples indicate adequate internal consistency and high test-retest reliability; significant correlations with the California Psychological Inventory (CPI) Social Maturity Index; consistent Q-sort portraits of high-scoring and low-scoring women; negligible correlations with test taking response styles, intelligence, and measures of psychopathology; and moderate developmental trends.     

Masculinity-femininity in creative college women.

The possible relationship between masculinity and creativity in college women was investigated through a battery of masculinity-femininity scales that tapped both manifest and latent masculinity, factorially derived clusters, and an ipsative measure. Two samples (n = 45 each) of women who had scored above the 75th percentile and below the 25th percentile respectively on two measures of creativity were used. High creative subjects scored higher on activity and described themselves as more masculine; indications are that they possess a broader, less stereotyped sex-role identity.
