Paradoxes in creativity and psychiatric conditions

Dimensions of manic symptoms in youth: psychosocial impairment and cognitive performance in the IMAGEN sample

“…Consistent with our second hypothesis, we found that the exuberant, but not the undercontrolled, dimension was positively and specifically associated with verbal intelligence. This finding is in keeping with suggestions about superior verbal performance in mania (Hurlow & MacCabe, ). We also showed that this association could not be explained by other personality characteristics, namely sensation seeking and extroversion.…”

“… First, in keeping with previous work (Brand et al., ; Holtmann et al., ; Stringaris et al., ) we expect that manic symptoms in adolescents can be parsed into two correlated dimensions: one of undercontrol, characterized by irritable and disinhibited symptoms that is associated with psychosocial impairment, and an exuberant dimension that does not contribute independently to psychosocial impairment. Second, we hypothesize that symptoms of exuberance will be positively associated with IQ scores, whereas symptoms of undercontrol will be negatively correlated with IQ. We expect that the exuberant dimension will be specifically associated with verbal IQ but not performance IQ, in keeping with suggestions about superior verbal performance in mania (Hurlow & MacCabe, ). To ensure that our findings are specific, we will also adjust for personality characteristics, such as sensation seeking or extraversion, as these have been suggested to correlate positively with intelligence in young people (Raine, Reynolds, Venables, & Mednick, ) and can also be related to manic symptoms (Bagby et al., ). Third, we expect that only symptoms of undercontrol, but not of exuberance, will be associated with measures of poor response inhibition as has been previously described for bipolar disorder (Bora, Yucel, & Pantelis, ).…”

“…We also showed that this association could not be explained by other personality characteristics, namely sensation seeking and extroversion. However, we note that next to accumulating evidence about superior cognitive performance in people at risk for BD (Hurlow & MacCabe, 2011), there are also studies that show no evidence of such an association (Zammit et al, 2004).…”

To ensure that our findings are specific, we will also adjust for personality characteristics, such as sensation seeking or extraversion, as these have been suggested to correlate positively with intelligence in young people (Raine, Reynolds, Venables, & Mednick, 2002) and can also be related to manic symptoms (Bagby et al, 1997).…”

Creative tendencies before a psychosis onset: Report based on the Swedish national cohort

“…Kod oba pristupa, kako su sugerisali Hurlow i McCabe, najbolje je sprovesti populacionu studiju [1] , jer sve što bi se izvodilo na manjim uzorcima može biti podložno "pristrasnosti" u uzorkova nju, pa samim tim i praćeno manje pouzdanim rezultatima. U ovom kontekstu, podaci nacionalnog registra Švedske pokazali su se kao dragocen material, koji je u poslednjoj deceniji analiziran kroz više dimenzija, postavši tako dragocen i jedinstven izvor informacija o povezanosti psihoza (afektivnih i neafek tivnih) sa kreativnošću − kako kod osoba sa već postavljenom dijagnozom, tako i kod onih koji su u premorbidnoj asimptomatskoj fazi.…”
