Neuroimaging predictors of treatment response in anxiety disorders.

Although several psychological and pharmacological treatment options are available for anxiety disorders, not all patients respond well to each option. Furthermore, given the relatively long duration of adequate treatment trials, finding a good treatment fit can take many months or longer. Thus, both clinicians and patients would benefit from the identification of objective pre-treatment measures that predict which patients will best respond to a given treatment.

Diminished rostral anterior cingulate cortex activation during trauma-unrelated emotional interference in PTSD.

Background: Previous research suggests that individuals with posttraumatic stress disorder (PTSD) preferentially attend to trauma-related emotional stimuli and have difficulty completing unrelated concurrent tasks. Compared to trauma-exposed control groups, individuals with PTSD also exhibit lower rostral anterior cingulate cortex (rACC) activation during tasks involving interference from trauma-related stimuli. However, it is not clear whether relatively diminished rACC activation in PTSD also occurs during interference tasks involving trauma-unrelated emotional stimuli.

An analysis of the determinants of the feeling of knowing.

Research has demonstrated that feeling-of-knowing (FOK) judgments are affected by the amount of accessible information related to an inaccessible target. Further, studies have demonstrated that, in some situations, FOK judgment magnitude is not only related to the amount (quantity) of accessed features, but also the correctness of those features (Thomas, Bulevich, & Dubois, 2011). The present study examined the conditions under which the correctness of features would influence FOK judgment magnitude.

Context affects feeling-of-knowing accuracy in younger and older adults.

In feeling of knowing (FOK) studies, participants predict subsequent recognition memory performance on items that were initially encoded but that cannot presently be recalled. Research suggests that FOK judgment magnitude may be influenced by the total amount, or quantity, of contextual information retrieved related to the unrecalled target (e.g.
