MethodsParticipants (N=54) received one of three mood inductions (one positive, two negative) and then performed an auditory signal detection task to assess reality discrimination. ResultsParticipants who received either of the two negative inductions made more false alarms, but not more hits, than participants who received the neutral induction, indicating that negative affect makes participants more likely to misattribute internal, self-generated events to an external, non-self source. LimitationsThese findings are drawn from an analogue sample, and research that examines whether negative affect also impairs reality discrimination in patients who experience auditory hallucinations is required. ConclusionsThese findings sho...

The effect of auditory verbal imagery on signal detection in hallucination-prone individuals

“…This supports previous research using source memory tasks, which found that words associated with traumatic events were not more likely to be externally misattributed ( Bendall et al, 2011 ), but stands in contrast to research suggesting that emotionally negative outcomes affect low-level sensorimotor agency ( Yoshie & Haggard, 2013 ) and higher-level attributional biases ( Mezulis et al, 2004 ). Previous research has, however, shown that inducing negative affect in participants causes an increase in the number of external misattributions on a typical auditory signal detection paradigm ( Hoskin et al, 2014 , Smailes et al, 2014 ). This might imply that the content of the inner speech does not play a role in its misattribution, but instead a general state of negative affect may cause an increase in the likelihood of external misattributions.…”

Imaginary Companions, Inner Speech, and Auditory Verbal Hallucinations: What Are the Relations?

“…An auditory signal detection task (SDT) was used modeled on those used by Smailes et al (2014) and Moseley et al (2014). Participants were asked to listen to 60 trials containing 5-s bursts of white noise, played over headphones.…”

Tailoring Cognitive Behavioral Therapy to Subtypes of Voice-Hearing

“…Fourth, some voice-hearers are thought to have a trait-like bias in their reality discrimination skills, so that they tend to misattribute internal, self-generated cognitions to an external, non-self source (Brookwell et al, 2013 ). Moreover, this bias can be exacerbated by negative affect (Hoskin et al, 2014 ; Smailes et al, 2014 ).…”
