- The ability to detect and localize sounds in an environment is critical for survival. Localizing sound sources is a computational challenge for the human brain because the auditory cortex seems to lack a topographical space representation. However, attention and task demands can modulate localization performance. Here, we investigated whether the localization performance for sounds occurring directly in front of or behind people could be modulated by emotional salience and sound-source location. We measured auditory-induced emotion by ecological sounds occurring in the frontal or rear perceptual fields, and employed a speeded localization task. The results showed that both localization speed and accuracy were higher, and that stronger negative emotions were induced when sound sources were behind the participants. Our results provide clear behavioral evidence that auditory attention can be influenced by sound-source location. Importantly, we also show that the effect of spatial location on attention is mediated by emotion, which is in line with the argument that emotional information is prioritized in processing. Auditory system functions as an alarm system and is in charge of detecting possible salient events, and alarming for an attention shift. Further, spatial processing in the auditory dorsal pathway has a function of guiding the visual system to a particular location of interest. Thus, an auditory bias toward the space outside the visual field can be useful, so that visual attention could be quickly shifted in case of emotionally significant information.

- Auditory attention theories suggest that humans are able to decompose the complex acoustic input into separate auditory streams, which then compete for attentional resources. How this attentional competition is influenced by motivational salience of sounds is, however, not well-understood. Here, we investigated whether a positive motivational value associated with sounds could bias the attentional selection in an auditory detection task. Participants went through a reward-learning period, where correct attentional selection of one stimulus (CS+) lead to higher rewards compared to another stimulus (CS-). We assessed the impact of reward-learning by comparing perceptual sensitivity before and after the learning period, when CS+ and CS-were presented as distractors for a different target. Performance decreased after reward-learning when CS+ was a distractor, while it increased when CS- was a distractor. Thus, the findings show that sounds that were associated with high rewards captures attention involuntarily. Additionally, when successful inhibition of a particular sound (CS-) was associated with high rewards then it became easier to ignore it. The current findings have important implications for the understanding of the organizing principles of auditory perception and provide, for the first time, clear behavioral evidence for reward-dependent attentional learning in the auditory domain in humans.

- Even though traditional psychoacoustics has provided indispensable knowledge about auditory perception, it has, in its narrow focus on signal characteristics, neglected listener and contextual characteristics. To demonstrate the influence of the meaning the listener attaches to a sound in the resulting sensations we used a Fourier-time-transform processing to reduce the identifiability of 18 environmental sounds. In a listening experiment, 20 subjects listened to and rated their sensations in response to, first, all the processed stimuli and then, all original stimuli, without being aware of the relationship between the two groups. Another 20 subjects rated only the processed stimuli, which were primed by their original counterparts. This manipulation was used in order to see the difference in resulting sensation when the subject could tell what the sound source is. In both tests subjects rated their emotional experience for each stimulus on the orthogonal dimensions of valence and arousal, as well as perceived annoyance and perceived loudness for each stimulus. They were also asked to identify the sound source. It was found that processing caused correct identification to reduce substantially, while priming recovered most of the identification. While original stimuli induced a wide range of emotional experience, reactions to processed stimuli were emotionally neutral. Priming manipulation reversed the effects of processing to some extent. Moreover, even though the 5th percentile Zwickers-loudness (N5) value of most of the stimuli was reduced after processing, neither perceived loudness nor auditory-induced emotion changed accordingly. Thus indicating the importance of considering other factors apart from the physical sound characteristics in sound design.

- Psychoacoustical research provided indispensible knowledge on how human audition works, which is necessary for successful sound design applications. It may, however, be argued that traditional psychoacoustics, in its narrow focus on signal characteristics, has neglected listener and contextual characteristics. Thus, to demonstrate the influence of meaning the listener attaches to a sound we used an FFT processing to reduce the identifiability of 18 environmental sounds, since source identification is central to meaning attribution. In a listening experiment, 20 subjects listened to and rated all the processed stimuli first and then original stimuli, without being aware of the existence of two sets. Another 20 subjects rated only the processed stimuli, which were primed by their original counterparts. This manipulation was used in order to see the difference when the subject could tell what the sound source is. In both tests subjects rated their emotional experience for each stimulus on the orthogonal dimensions of valence and arousal, as well as perceived annoyance and perceived loudness for each stimulus. They were also asked to identify the sound source. It was found that processing caused correct identification to reduce substantially, while priming recovered most of the identification. While original stimuli induced a wide range of emotional experience, reactions to processed stimuli were affectively neutral. Priming manipulation reversed the effects of processing to some extent. Moreover, even though Zwickers-loudness value of most of the stimuli was reduced after processing, perceived loudness was only decreased for affectively negative stimuli.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents a new research project, which aims toreveal the elements of haptic sensation in playing pipeorgan with mechanical tracker actions. In order to reach this goal sets of experiments will be carried out. Layout of these experiments are (1) measuring manual key signatures and analyzing them together with the interviews with expert organists to study the extent they can feel and communicate key properties, (2) measuring dynamical properties of key action, recording sound and recording organist’s movements simultaneously during performance, and (3) running psychophysical experiments on expert organists using an experimental keyboard where key action can be simulated and altered. The outcome of this research project will contribute to organ building and documentation and new class of haptics-enabled digital musical instruments.

Negative emotion provides cues for orienting auditory spatial attention

Tidskriftsartikel (refereegranskat)abstract
- The auditory stimuli provide information about the objects and events around us. They can also carry biologically significant emotional information (such as unseen dangers and conspecific vocalizations), which provides cues for allocation of attention and mental resources. Here, we investigated whether task-irrelevant auditory emotional information can provide cues for orientation of auditory spatial attention. We employed a covert spatial orienting task: the dot-probe task. In each trial, two task irrelevant auditory cues were simultaneously presented at two separate locations (left-right or front-back). Environmental sounds were selected to form emotional vs. neutral, emotional vs. emotional, and neutral vs. neutral cue pairs. The participants’ task was to detect the location of an acoustic target that was presented immediately after the task-irrelevant auditory cues. The target was presented at the same location as one of the auditory cues. The results indicated that participants were significantly faster to locate the target when it replaced the negative cue compared to when it replaced the neutral cue. The positive cues did not produce a clear attentional bias. Further, same valence pairs (emotional-emotional or neutral-neutral) did not modulate reaction times due to a lack of spatial attention capture by one cue in the pair. Taken together, the results indicate that negative affect can provide cues for the orientation of spatial attention in the auditory domain.

- Research regarding the perception of sound focuses in large on the acoustical properties of the sound. We argue that, for a more complete picture of sound perception, one must take the non‐physical properties into account. By changing the emotional descriptor of a sound the perception in terms of level of annoyance will change. The present study investigates how a priming picture placing the origin of the sound in either a positive or negative environment affects the level of annoyance to same sound. Three different sounds were used in the experiment, all based on pink noise. The participants were, in the beginning of each sound, exposed to a picture telling where the sound originated. The picture was either a positive environment (a picture of a waterfall) or a negative environment (a picture of a larger factory). While listening to the sounds the participants completed different performance tasks. In the end of each sound the participants rated the level of annoyance. Results show that the annoyance ratings are significantly lower when primed with a positive picture. Results also indicate that for more attention demanding tasks this correlation is stronger. The findings are discussed in relation to theories of sound perception.

- This paper investigates how different types of data from psychoacoustical experiments may be combined to render further knowledge about the mechanisms underlying sound perception. Two studies were conducted with auditory alerts of short duration. First, an experiment where participants rated the dissimilarity among the auditory alerts was performed. This resulted in a two-dimensional multi-dimensional scaling solution. Second, an experiment where participants evaluated the stimuli with semantic descriptors and rated their emotional reactions to the sounds was performed. The output of this experiment was a reduced set of underlying perceptual and emotional dimensions. The results of the two experiments were then integrated by the use of multi-dimensional perceptual unfolding and a set mediation analyses. The integrative analyses showed that part of the cognitive categorization of the semantic descriptors was mediated by the emotional reactions to the sounds. The results are discussed in relation to theories of auditory perception and emotional response categorization.
