Using international emotional picture sets in countries suffering from violence

Focused on the negative: emotions and visuospatial attention in generalized anxiety disorder

Global-local visuospatial attention is a core mechanism which highly affects the way we process our visuospatial environment. The current study aimed to examine the effect of negative emotions on global-local visuospatial processing in participants with generalized anxiety disorder (GAD) and in healthy controls (HCs). Participants performed two versions of the global-local-arrow task: they were asked to determine the direction (left or right) of the global arrow or of the local arrows that composed it, with or without emotional prime-cues. In the non-emotional task and in the neutral-valence condition of the emotional task, the GAD group did not differ from that of HCs - both groups exhibited a classic global processing bias (reactions to the global dimension were faster and less affected by the local dimension). In the negative-valence condition, global processing bias was only slightly reduced in HCs and almost completely eliminated in the GAD group. The results of the current study suggest that, in non-emotional conditions, global processing bias does not differ significantly between individuals with GAD and HCs. However, task-irrelevant negative cues were found to have a greater impact in reducing global bias for individuals with GAD compared to HCs. Potential implications are discussed.

A Systematic Review of International Affective Picture System (IAPS) around the World

Standardized Emotion Elicitation Databases (SEEDs) allow studying emotions in laboratory settings by replicating real-life emotions in a controlled environment. The International Affective Pictures System (IAPS), containing 1182 coloured images as stimuli, is arguably the most popular SEED. Since its introduction, multiple countries and cultures have validated this SEED, making its adoption on the study of emotion a worldwide success. For this review, 69 studies were included. Results focus on the discussion of validation processes by combining self-report and physiological data (Skin Conductance Level, Heart Rate Variability and Electroencephalography) and self-report only. Cross-age, cross-cultural and sex differences are discussed. Overall, IAPS is a robust instrument for emotion elicitation around the world.

Presenting KAPODI – The Searchable Database of Emotional Stimuli Sets

Emotional stimuli such as images, words, or video clips are often used in studies researching emotion. New sets are continuously being published, creating an immense number of available sets and complicating the task for researchers who are looking for suitable stimuli. This paper presents the KAPODI-database of emotional stimuli sets that are freely available or available upon request. Over 45 aspects including over 25 key set characteristics have been extracted and listed for each set. The database facilitates finding of and comparison between individual sets. It currently contains sets published between 1963 and 2020. A searchable online version ( https://airtable.com/shrnVoUZrwu6riP9b ) allows users to select specific set characteristics and to find matching sets accordingly, as well as to add new published sets.

Dynamic modulation of emotional processing

Recent findings suggest the processing of emotional stimuli is prioritized compared to neutral stimuli; however, it is not necessarily automatic and depends on several modulating factors. The current paper highlights three major factors that affect the reactions to emotional stimuli: (i) stimulus properties, (ii) task demands and attention, and (iii) individual characteristics. The evidence reviewed here suggests that individual characteristics shape the structure, function and connectivity within a neural network that is involved in the reactions to emotional stimuli. This neural network includes regions related to emotion and attention, in line with evidence for reciprocal connections between these two processes. Activation in this network further depends on the emotional value of a certain item, as well as physical features of the stimulus. This integrative view can lead to better understanding of the underlying mechanisms of emotional reactions, as well as better therapeutic approaches.
