Compare changes in art quality before and after the onset of progressive nonfluent aphasia (PA).
Some patients with left frontotemporal lobar degeneration (FTLD), particularly PA start painting and improve in art despite their disease. There is only 1 case reported of FTLD where the person was an artist before onset.
Digital images of 7 paintings were obtained. Three paintings were from 6 years before onset of PA, 1 was from year of onset, and 3 were from 5 years after. Seven college-educated raters without art backgrounds, 5 men and 2 women, used a 1 to 5 point scale to rate 4 qualities of the paintings: representation, esthetics, novelty, and closure. The subjects had not previously viewed these paintings. One art expert also rated the paintings on these 4 qualities.
Quality ratings did not differ for 3 qualities, but novelty decreased over time. The art expert rated all qualities stable over time.
Artistic ability in this previously trained artist with PA did not improve. Instead, the novelty of her work decreased. FTLD may not improve artistic skills in those who already possess them and there can be a decrease in one quality strongly related to creativity-novelty.
比较进行性非流畅性失语(PA)发病前后艺术质量的变化。
一些左额颞叶变性(FTLD)患者,尤其是PA患者,尽管患病仍开始绘画并在艺术方面有所进步。仅报告了1例FTLD病例,患者在发病前是一名艺术家。
获取了7幅画作的数字图像。3幅画作来自PA发病前6年,1幅来自发病当年,3幅来自发病后5年。7名没有艺术背景的受过大学教育的评分者(5名男性和2名女性)使用1至5分的量表对画作的4种质量进行评分:表现、美学、新颖性和完整性。这些受试者此前未曾看过这些画作。一名艺术专家也对这些画作的这4种质量进行了评分。
3种质量的评分没有差异,但新颖性随时间下降。艺术专家认为所有质量随时间保持稳定。
这位先前受过训练的患有PA的艺术家的艺术能力没有提高。相反,她作品的新颖性下降了。FTLD可能不会提高那些已经具备艺术技能者的艺术技巧,并且与创造力密切相关的一种质量——新颖性可能会降低。
