Misophonics showed accuracy-over-speed bias and excessive cognitive control on a stop-signal task, supporting classification within the obsessive-compulsive spectrum

Eijsker 2019 stop signal task study supports the view that misophonia is a distinct psychiatric condition, potentially within the obsessive-compulsive spectrum. Patients showed a response bias favoring accuracy over speed, elevated psychopathology scores, and neural patterns indicative of excessive cognitive control and self-monitoring (evident by greater left DLPFC activation during correct going than during successful inhibition — the reverse of controls — suggesting they engage more cognitive control to slow their responses rather than during inhibition itself.) , traits aligned with perfectionism and compulsivity rather than impulsivity. These behavioral and neural findings parallel features observed in OCD, including rigid rule adherence and intolerance of mistakes, suggesting misophonia may be more appropriately classified within the obsessive-compulsive and related disorders framework.

Response Bias Favoring Accuracy Over Speed (Perfectionism / Behavioral Inflexibility Framing)

A stop-signal task study found that individuals with misophonia exhibited a response bias favoring accuracy over speed, accompanied by elevated psychopathology scores and neural patterns suggesting excessive cognitive control and self-monitoring. The authors interpreted this pattern as consistent with traits such as perfectionism and compulsivity, rather than impulsivity, aligning misophonia with behavioral styles characterized by rigid rule adherence and intolerance of mistakes. (Eijsker et al., 2019)

Response Bias / Accuracy–Over–Speed (Inhibition Task Framing)

In a stop-signal task examining inhibitory control, participants with misophonia demonstrated a bias toward prioritizing response accuracy over speed. This behavioral pattern suggests an altered response strategy during inhibitory control tasks, indicating that individuals with misophonia may adopt more cautious response strategies when performing tasks requiring response inhibition. (Eijsker et al., 2019)

Behavioral Inflexibility and Perfectionism Linkage in Stop-Signal Task Findings

Neural and behavioral results from a stop-signal task study suggested that individuals with misophonia show patterns consistent with behavioral inflexibility and perfectionism, including increased cognitive control and heightened self-monitoring during task performance. These features resemble traits commonly associated with obsessive–compulsive spectrum conditions, such as rigid adherence to rules and intolerance of errors. (Eijsker et al., 2019)
