ResumoIntrodução: A forma como estímulos emocionais são processados e se relacionam com a cognição possui diversas implicações no campo da saúde mental. Há, portanto, a necessidade de instrumentos efetivos que viabilizem a mensuração da emoção. Objetivos: Criar, a partir do International Affective Picture System (IAPS), 20 conjuntos de fotos associadas temática, visual e emocionalmente, e eleger a foto mais representativa de seu respectivo conjunto; investigar a correlação entre os fatores de associação (emocional, temática e visual); e verifi car a correlação de emocionalidade dos 20 conjuntos com os dados da versão brasileira do IAPS. Método: Um total de 353 participantes avaliaram e julgaram o quão associadas entre si eram as fotos de cada conjunto e qual era a foto mais representativa de cada conjunto. Resultados: Dezoito dos 20 conjuntos demonstraram alta associação nos três fatores investigados. Em todos os conjuntos, foram obtidas hierarquias de representatividade. Houve signifi cativa correlação positiva entre os fatores de associação temática e visual (coefi ciente de correlação de Spearman, rho = 0,820; p < 0,01). Observou-se correlação signifi cativa tanto dos escores de valência (rho = 0,958) quanto dos escores de alerta (rho = 0,836; p < 0,01) para com os dados da versão brasileira nos 20 conjuntos. Conclusões: O material desenvolvido propicia a neurocientistas a possibilidade de manipulação e controle de variáveis relacionadas ao processamento emocional, e também pode contribuir para investigações com enfoque psiquiátrico. Descritores: IAPS, emoção, nível de alerta, imagens, avaliação em saúde. Abstract Introduction:The way in which emotional stimuli are processed and relate with cognition has many implications in the mental health fi eld. As a result, there is a need for effective instruments that allow measuring emotion. Objectives: To create 20 sets of thematically, visually, and emotionally associated pictures using the International Affective Picture System (IAPS), and to select the most representative picture in each set; to investigate the correlation between associative factors (emotional, thematic, and visual); and to assess the emotional correlation between the 20 sets and Brazilian normative data. Methods: A total of 353 participants evaluated the sets and defi ned to what degree the pictures in each set were associated with one another, and also which picture was the most representative of each set. Results: Eighteen of the 20 sets presented high association results in the three factors assessed. Hierarchical representations were obtained for the 20 sets. There was a signifi cant positive correlation between thematic and visual association (rho = 0.820; p < 0.01). Both valence (rho = 0.958) and arousal (rho = 0.836; p < 0.01) were signifi cantly correlated with Brazilian norms in all 20 sets. Conclusions: The sets of associated pictures created and herein described may be useful to neuroscientists, due to the possibility of manipulating and controlling variables related to emotional pro...
