Analysis of a Divergent Thinking Dataset
No full textDear Colleagues,
The Journal of Intelligence plans a special issue on the analysis of a divergent thinking dataset.
• The data are available right here!
• The main data are available for three Alternate Uses Objects (i.e., garbage bag, paperclip, and rope)
• The dataset includes many different scorings of the divergent thinking data such as variants of originality scorings (human ratings, statistical rarity, and semantic distance), as well as fluency and elaboration.
• Data for each single response are also available. This includes ratings of single responses, as well as text-mining features obtained for single responses, for example.
• Person-level covariates are also available (e.g., verbal fluency, typing speed, right-wing authoritarianism), but divergent thinking should always be part of the analysis performed.
• For an example of how the data can be analyzed, see:

We welcome all manuscripts which contribute to an understanding of new analytical approaches for researchers interested in divergent thinking research, a new understanding of the data, and/or to the measurement of divergent thinking, whether related or not to the approaches used in the papers mentioned above. Any type of analysis qualifies on the condition that it is of a sufficiently high level of quality. Specifically, the analysis could be…
• …simple or complex
• …outdated (some approaches used in the past might still be useful while other “old” methods of data analysis were simply overlooked) or modern (i.e., the newest approaches taken from the methods literature)
• …frequentist or Bayesian
• …psychometric (classical test theory, item response theory, or network psychometrics)
• …focused on prediction
The deadline for submission is 31st of July 2025. Submitted manuscripts will be subjected to the regular review process.

Heinz Forthmann and Darcy Ribeiro : documentary film on the Brazilian Indiens Service, SPI, 1949/1959
No full textOrientadores: Fernão Vitor Pessoa de Almeida RamosTese (doutorado) - Universidade Estadual de Campinas, Instituto de ArtesResumo: Esta pesquisa estuda o trabalho conjunto realizado pelo fotógrafo e cineasta Heinz Forthmann (1915-1978), brasileiro por opção, e pelo antropólogo Darcy Ribeiro (1922-1997) na Seção de Estudos, SE, do SPI. Criada em 1942 pelo indigenista Cândido Mariano da Silva Rondon, a SE tinha entre seus objetivos pesquisar e documentar em fotografia, cinema e gravação sonora, a vida, os ritos e as manifestações culturais dos povos indígenas do Brasil. As diretrizes de documentação etnográfica, criadas inicialmente por Harald Schultz, foram desenvolvidas, a partir de 1949, por Darcy Ribeiro, que buscou a integração entre pesquisas etnológicas, lingüísticas e a realização cinematográfica. Este ciclo de trabalho se estendeu até 1959, e gerou importantes filmes documentários que hoje se encontram dispersos, fragmentados ou perdidos, entre os quais: Os Índios Urubus, 1950; Funeral Bororo, 1953; Txukahamãe, 1955, e Jawari, 1957. É a memória desses filmes, o conhecimento de sua arte e método de realização etnográfica que este trabalho procura recuperarRésumé: Cette recherche étudie le travail conjoint réalisé entre le photographe et cinéaste Heinz Forthmann (1915-1978), Brésilien par option, et l¿anthropologue Darcy Ribeiro (1922-1997) à la Seção de Estudos, SE, du SPI.

Fifty Years Later and Still Working: Rediscovering Paulus et al.’s (1970) Automated Scoring of Divergent Thinking Tests
No full textAutomated scoring of divergent thinking tasks is a current hot topic in creativity research. Most of the debated approaches are unsupervised machine learning approaches and researchers seemingly just started to evaluate supervised approaches. Hence, rediscovering the seminal work of Paulus et al. (1970) came as a big surprise to us. More than fifty years ago, they derived prediction formulas for an automated scoring of the Torrance Test of Creative Thinking that was based on a set of text mining variables (e.g., average word length, word counts, and so forth). They found quite impressive cross-validation results. This work reintroduces Paulus et al.’s (1970) approach and investigates how it performs compared to semantic distance scoring. The main contribution of Paulus et al.’s (1970) neglected masterpiece on divergent thinking assessment is echoed by the findings of this work: Creative quality of responses can be well predicted by means of simple text mining statistics. The validity was also stronger as compared to semantic distance. Importantly, using the Paulus et al. (1970) features in a state-of-the-art supervised machine learning approach does not outperform the simple stepwise regression used by Paulus et al. (1970). Yet, we found that supervised machine learning can outperform the Paulus et al. (1970) approach, when semantic distance is added to the set of prediction variables. We discuss challenges that are expected for future research that aim at combining unsupervised approaches based on word embeddings and supervised learning relying on text mining features
