“…The IAPS contains more than one thousand color photographs depicting real aspects and situations in life with standardized norms in three dimensions (affective valence, arousal and dominance) obtained in different countries around the world (e.g. Deák, Csenki, & Révész, 2010;Lasaitis, Ribeiro, Freire, & Bueno, 2008;Moltó et al, 1999;Silva, 2011;Soares et al, 2015;Verschuere, Crombez, & Koster, 2001). Although the IAPS remains widely cited, there are some reasons that explain the emergence of additional standardized pictures sets: (1) the intensive use of the IAPS stimuli in the same lab may produce a lost in part of its emotional power; (2) the range of situations represented by the IAPS pictures is wide but the number of available stimuli within the same topic is too small to be able to design studies with a elevated number of trials; (3) most of the pictures are over one or two decades old, so their quality is poor, or they are unfortunately outdated and unsuitable for the contemporary generation.…”

MATTER in emotion research: Spanish standardization of an affective image set

et al. 2021

Pictures with affective content have been widely used in the scientific study of emotions from two main approaches. On the one hand, the dimensional theories claiming that affective experiences can be described according to a few fundamental dimensions such as valence and arousal. On the other hand, the discrete-category theories proposing the presence of a number of basic and universal emotions. Although it has been demonstrated that these two approaches are not mutually exclusive, the existing standardized affective picture databases have been created from the dimensional perspective, which entails important gaps for research focused on discrete emotions.The present work introduces MATTER, a new database composed by 540 pictures depicting disgusting, fearful, neutral, erotic, mirthful and incongruent contents, and provides normative values (total N = 368, mean =120.47 ratings/picture) in valence and arousal dimensions, as well as in discrete affective (disgust, fear, erotica and mirth) and cognitive (incongruence and interest) features. A tentative classification into discrete categories is presented and physical properties of each picture are reported. Our findings suggest that MATTER constitutes a modern and suitable set of affective images including for first time both mirth and incongruence related pictures. Additionally, it will allow the examination of affective and cognitive processes in fear/disgust and humor/incongruence fields.

“…We selected 36 digital pictures from the International Affective Pictures System -IAPS (Lang, Bradley & Cuthbert, 1997) and divided them evenly into three conditions: 1) negative valence and high arousal; 2) positive EMOTION AND EARLY AUDITORY PROCESSING 7 valence and high arousal; and 3) neutral valence 1 . We categorized these pictures based on the scores obtained in the Brazilian adaptation of the test (Lasaitis et al, 2008). We established an additional control condition, with a non-picture presentation, by presenting a white screen.…”

Emotion influences how we perceive the world, but the neural substrates of this modulationare not completely understood. Here, we aimed to evaluate how emotional state modulatesthe early sensory processing of auditory stimuli. We recorded auditory event-relatedpotentials while participants were listening to neutral tones and watching emotionalpictures simultaneously. To verify the emotional responses, we collected the subjectiveassessment of pictures, heart rate, and brain rhythms. We found that the emotional statesfailed in modulating N1 and P2 amplitudes. However, N1 amplitude decreased when wepresented a picture, compared to a white background. These results suggest a suppressedemotional modulation over the processing of periodic neutral events, probably due to thepredictability of these events. Nonetheless, we observed a deceleration of the heart rateduring presentation of emotional pictures and an increase in theta power during thepresentation of positive pictures, which confirms the induction of emotional reactions.

“…To our knowledge, only a few sets of visual stimuli have norms for the Brazilian population. These data sets include the IAPS [22,23], the 400-pictures of objects of Cycowicz et al set [7], the locally developed data set of 89 pictorial stimuli for Brazilian middle aged and elderly individuals [24], and the White, Pardo, and Black Children Picture Set (BIC-Multicolor) composed of 120 portraits of children of 6–12 years of age from different races [25]. Although these data sets have been useful for research with Brazilian samples, a data set of realistic pictures of objects are still lacking for this population.…”

Brazilian norms for the Bank of Standardized Stimuli (BOSS)

et al. 2019

Norms for visual stimuli are critical for designing reliable psychological and neuroscientific studies. However, such normative sets of stimuli are scarce for the Brazilian population. Here, we report norms for the Bank of Standardized Stimuli (BOSS) for Brazilian college students. Sixty-five Brazilian university students rated the initial normative set of BOSS images for familiarity and visual complexity, and produced a name for each object. Data analysis focused on comparing the present norms to prior BOSS norms (English-Canadian, French-Canadian, and Thai) across four normative dimensions: familiarity, visual complexity, modal name agreement, and H value, and considered these dimensions according to whether items pertained to living or non-living domains. Correlation analyses revealed that the present norms show strong similarities to prior BOSS norms, although objects were scored as more familiar in the Brazilian relative to all prior norms, especially relative to the Thai norms. In addition, familiarity was greater for living than for non-living items in the English- and French-Canadian norms, but such difference was absent in the Brazilian and Thai norms, suggesting that familiarity is more strongly affected by culture than by semantic domain. In sum, even when cultural differences are considered, the current study reveals that the images of the BOSS data set are in general well known for Brazilians, demonstrating that they can be useful for psychological and neuroscientific research in Brazil.
