Affective auditory stimulus database: An expanded version of the International Affective Digitized Sounds (IADS-E)

Abstract

Using appropriate stimuli to evoke emotions is especially important for researching emotion. Psychologists have provided several standardized affective stimulus databases-such as the International Affective Picture System (IAPS) and the Nencki Affective Picture System (NAPS) as visual stimulus databases, as well as the International Affective Digitized Sounds (IADS) and the Montreal Affective Voices as auditory stimulus databases for emotional experiments. However, considering the limitations of the existing auditory stimulus database studies, research using auditory stimuli is relatively limited compared with the studies using visual stimuli. First, the number of sample sounds is limited, making it difficult to equate across emotional conditions and semantic categories. Second, some artificially created materials (music or human voice) may fail to accurately drive the intended emotional processes. Our principal aim was to expand existing auditory affective sample database to sufficiently cover natural sounds. We asked 207 participants to rate 935 sounds (including the sounds from the IADS-2) using the Self-Assessment Manikin (SAM) and three basic-emotion rating scales. The results showed that emotions in sounds can be distinguished on the affective rating scales, and the stability of the evaluations of sounds revealed that we have successfully provided a larger corpus of natural, emotionally evocative auditory stimuli, covering a wide range of semantic categories. Our expanded, standardized sound sample database may promote a wide range of research in auditory systems and the possible interactions with other sensory modalities, encouraging direct reliable comparisons of outcomes from different researchers in the field of psychology.

Assessments of Acoustic Environments by Emotions – The Application of Emotion Theory in Soundscape

“…The IADS database consists of 167 natural sounds of 6 s duration that are common in daily life, which elicit different responses on the affective dimensions of valence, arousal, and dominance (Choi et al, 2015). Yang et al (2018) confirmed the findings of Bradley and Lang and observed that the relationship between a physical intensity of sound and valence looked more complex and that classical level indicators explained only a few percentage points of the total variance. Figure 3 proposes a conceptual framework for understanding the process of emotional responses triggered by a soundscape, drawing from the various outcomes of previous research on emotions induced by acoustic environments.…”

“…It seems that environmental sounds carry biologically significant information reflected in human emotional responses, and that emotions work to optimize adaptive responses to biologically meaningful events (Ma and Thompson, 2015). However, research on the auditory system has been less intensively performed in the past than research on the visual system (Yang et al, 2018).…”

“…In daily life, the various types of external stimuli that humans receive across different modalities have powerful effects on evoked emotions, influencing decision-making and subsequent behavior (Yang et al, 2018). However, the link between external stimuli and elicited emotions is still subject to extensive research.…”

EEG-Based BCI Emotion Recognition: A Survey

“…The International Affective Picture System (IAPS) [ 31 ] and the International Affective Digitized Sound System (IADS) [ 32 ] are the most popular resources for emotion elicitation. These datasets provide emotional stimuli in a standardized way.…”
