Abstract Introduction Misophonia is a recently defined disorder in which certain aversive repetitive sounds and associated stimuli elicit distressing and impairing affective, behavioral, and physiological responses. The responses in misophonia may be stronger when the sound is produced by close friends and family, suggesting that the context in which a triggering cue occurs may have an important role in misophonia. As such, the goal of this study was to test experimentally whether the context of the sound source influences affective and psychophysiological responses to triggering stimuli in misophonia. Methods Sixty one adults with misophonia and 45 controls listened to audio recordings (8 s) of human eating, animals eating, and human mouth smacking sounds (without eating). After a break, the same audio recordings were presented embedded within videos of human eating (congruent stimuli), animals eating (congruent stimuli), and, in the mouth smacking condition, with visually incongruent stimuli (hands playing in mud or in a bowl with a watery dough). Psychophysiological responses—skin conductance response (SCR) and heart rate (HR), and self-reported affective responses (valence, arousal, dominance) were gathered during the experiment in a laboratory. Results Participants with misophonia assessed all the stimuli as more negative and arousing than the controls, and reported feeling less dominant with respect to the sounds. Animal and mouth smacking sounds were assessed by all the participants as less negative and arousing than human eating sounds, but only in the audio-video conditions. SCR data partially confirmed increased psychophysiological arousal in misophonia participants during an exposure to mouth sounds, but did not reflect the self-report changes in response to different contexts. Misophonia participants had deeper deceleration of HR than controls during human eating sound with congruent video stimuli, while there was no group difference during human mouth smacking with incongruent video stimuli. Conclusion Results suggest that the context of mouth sounds influences affective experiences in adults with misophonia, but also in participants without misophonia. Presentation of animal eating sounds with congruent visual stimuli, or human mouth smacking sounds with incongruent stimuli, decreased self-report reaction to common misophonic triggers.

Does context matter in misophonia? A multi-method experimental investigation

Status:: #status/reviewed


Metadata


Article Review Table: (Siepsiak et al., 2023)

Background/Purpose Background-
• there is question as to if/how the context of triggers impacts the Misophonic response

Purpose-
• asses if/how the source of a Misophonia triggers influences the physiological and emotional Misophonic response (page 1)
• look at how context influenced physiological resposnes to triggers by manipulating the source (human vs animal) and the visualization of the source ( congruent vs incongruent video of sounds) (page 3)

predictions-
• • it was assumed that no effects of condition would be seen in the control group
• the Misophonic group would asses all stim as more negative, more arousing, and feeling less dominant compared to controls across all contexts
• higher HR and less pronounced HR decline for the Misophonia group compared to controls cross all contexts.
• reduced physiological response to
• Misophonics would assess congruent  animal noise/video and incongruent human noise/video as less negative/arousing and feel more dominant compared to the inverse.
• reduced response to animals when shown with videos (as opposed to audio only). (page 4)
Participants/samples • 61 Misophonics , 45 controls based on scores on the MisoQuest    
• recruited from social media, radio, and local news ads. subjects pre-screened with the MisoQuest
Measures self reports of emotinal response- used self report to measure the primary dimensions of Mehrabian and Russell,(1974) emotional evaluation: valance ( pleasurable/dis-pleasurable) arousal (arousal/relaxation) and control (dominance/submission)

• Self-Assessment Manikin
Procedures Stimuli
• videos gotten from YouTube/created by the authors. text gives little details about the specifics of the stim.

Procedure    
• subjects briefed on the task, being informed that they would be shown video's with sound that may be neutral, aversive or pleasant.
• they had a button they could press to stop sounds immediately or end the experiment immediately.
• subjects were presented a series of 8s audio recording of triggers (human eating. animal eating, and human mouth smacking without eating) and given no context for the sounds. after a break,  the same stim were shown but embedded in videos that matched the source ( congruent condition) or did not match the source ( incongruent).
• subjects reported affective responses using the Self-Assessment Manikin scales after each stim presentation ( for both the audio only and audio-video parts)
• physiological responses (SCR, HR)  were recorded throughout (page 6)
Results • Misophonics rated all stim more aversively/arousing with less dominance then controls did
• all subjects rated animal/mouth smacking as less aversive then eating sounds in the audio-Video condition.
• mouth smacking induced partial increases in physiological arousal but this was not reflected in self reported changes in responses in different contexts.  
• deeper HR deceleration for Misophonics in the congruent audio-video human eating condition, but no group differences for mouth smacking (page 1)
• congruent animal eating sounds/visuals and incongruent human eating sounds/visuals associated with reduced self reported misophonia responses (page 1)
Discussion/Limits Conclusion-
• results suggest the context of mouth sounds alters the affective experience  of both Misophonics and controls (page 1)
• findings are consistent with role of context in miso. specifically, miso response is reduced for non-human sources (page 13)

Limitations:: • small selection of possible stimuli, and limited info on the details of said stimuli.
Future Directions:: • the authors call for future research to replicate research findings on role of context on miso response in sample suffering significant impairments with the use of clinical interviews instead of questionnaires.
• author calls on future research looking into moderators other then jsut context on Misophonics resposnes ( ex: personal experience, mental state, etc.)
Relevance:: • a good source on possible methods of getting physiological measurements of miso responses. Specifically, HR and SCR
• used a method like the Samermit 2022 source swapping video study top see how context influenced affective resposnes to triggers
• showed strong role of identifying the stim and context on the Intensity of Misophonic resposnes.

  1. Heart Rate (HR):
        
        - No main group effects were found in the analysis, indicating no significant difference in HR reaction to stimuli between individuals with misophonia and controls.
        - Significant interactions were observed between Group, Stimuli, Presentation, and Time, showing that participants with misophonia had significantly deeper HR deceleration than controls in specific conditions, such as the audio-video human eating condition.
        - The study highlighted the importance of considering the influence of visual information on the psychophysiological reactions to common misophonic stimuli.
  2. Skin Conductance Response (SCR):
        - No Group main effect was found in the analysis of different stimuli conditions, suggesting that there was no significant difference in SCR between individuals with misophonia and controls in response to specific stimuli presentations.

In the study by Siepsiak et al. (2023), the researchers found that the heart rate (HR) results were more challenging to interpret due to several factors:

  1. Lack of Clear Group Differences:
         
         - In most of the analyses, no significant differences in HR responses were observed between individuals with misophonia and controls.
         - The absence of consistent group differences in HR reactions to stimuli made it difficult to draw definitive conclusions about the physiological responses in individuals with misophonia.
  2. Contradictory Results:
         
         - One notable finding was the deeper HR deceleration in participants with misophonia compared to controls during the presentation of congruent human eating sounds in the audio-video condition.
         - This result contradicted the hypothesis that there would be less pronounced deceleration in HR during human eating sounds, suggesting a potential orienting response rather than the expected pattern of response.
  3. Attentional Processing and Orienting Response:
         
         - The observed HR patterns may be related to cognitive and attentional processing of the stimuli, indicating increased attentional focus on misophonic triggers.
         - The results suggested that individuals with misophonia may exhibit an orienting response to specific stimuli, potentially reflecting heightened sensitivity or significance attributed to certain sounds.

Overall, the complexity and variability in the HR results, including the lack of consistent group differences and unexpected patterns of response, made it challenging to provide a straightforward interpretation of the physiological data in relation to misophonia
