Complex Scenes From the International Affective Picture System (IAPS)

Abstract

Abstract. Complex scenes from standardized stimuli databases such as the International Affective Picture System (IAPS) are organized dimensionally rather than discretely. Further, the potentially unique function of socially relevant scenes is often overlooked. This study sought to identify discrete categories of complex scenes from the IAPS and to explore if there were qualitative features that make the emotional content of some social scenes identifiable with higher levels of agreement. One hundred and three participants (53.4% female, mean age 24.4) judged 118 IAPS scenes as reflecting fear, happy, sad, or neutral. A second judgment study was conducted with a separate group of participants ( N = 117; 79.2% female; mean age 30.41) to further characterize valid affective scenes across the full range of basic emotions. Sixty images received agreement on their emotional category from >70% of judges and were considered valid. IAPS identifier codes for these images are available for reference (along with the supplementary material from the second judgment study), organized by emotional and social content. An incidental observation was such that compared to nonsocial scenes, lower agreement rates were observed for social scenes across the board. Qualitative features of social scenes that were classified into emotional categories based on higher levels of agreement are discussed.

Assessing Motivational Biases in Brain and Behavior: Event-Related Potential and Response Time Concomitants of the Approach-Avoidance Task

“…Given that neutral images in current work included many complex scenes, meanwhile, current findings could reflect a bias toward increasing the size of those scenes that, despite (or because of) their emotional neutrality, perhaps invited exploration and disambiguation (cf. Wei, Roodenrys, Miller, & Barkus, 2020). Taken as a whole, current results could then suggest that AAT neurobehavior modulations can be influenced by other features (e.g., interest value) when emotional intensity is minimal, whereas they are increasingly influenced by general facilitation of approach/ avoid action as emotional intensity increases and then are more strongly biased toward specific emotion-congruent (avoidance or approach) action when emotional intensity is maximized.…”

Effects of affectively-loaded childhood-related photos from the IAPS on the induction of involuntary autobiographical memories in young and older adults

“…We chose a collection of five pictures representing childhood for use in our study. The slides are tagged with standardized valence values, so that experimental stimuli were classified as negative, neutral or positive in emotional content (Wei et al, 2020). Drawing on the standardized ratings provided with the tool, we used the following pictures: 2299 and 5,831 (positive stimuli); 2,345 and 9,041 (negative stimuli); and 2,312 (neutral stimulus) (Lang et al, 2008).…”

“…En el marco de este paradigma, el Sistema Internacional de Imágenes Afectivas (International Affective Picture System, IAPS, según su nombre en inglés, Lang et al, 2008) es una base muy utilizada a la hora de diseñar experimentos que requieran la inducción de emociones (Moltó et al, 2013). Encontramos variadas investigaciones actuales que utilizan dichos estímulos, en diseños que incluyen tanto variables cognitivas como fisiológicas, para estudiar distintos procesos psicológicos (p. e., Barbosa De la Torre et al, 2019;Bradley et al, 2017;Brush et al, 2021;Choi et al, 2017;Gantiva et al, 2018;Hartman et al, 2021;Álvarez-San Millán et al, 2022;Navalón et al, 2021;Pham et al, 2021;Robinson et al, 2021;Rohr et al, 2022;Sambuco, Costa, et al, 2020;Sege et al, 2020;Sill et al, 2019;Snowden et al, 2016;Ventura-Bort et al, 2022;Wang et al, 2021;Wei et al, 2020;Weymar et al, 2018;Wiens et al, 2022).…”
