SR140333B ((S)1-3-(3,4-dichloro-phenyl)-3-[2(4-phenyl-1-aza-bicyclo[2.2.2]oct-1-yl]-ethyl]-piperidin-1-yl-2-(3-isopropoxy-phenyl)-ethanone benzenesulfonate) was a kind gift from Sanofi-Aventis, France. The results are presented as the mean ± S.E.M. The statistical significance among the groups was assessed using one-way analysis of variance followed by Bonferroni’s post-hoc test. P values lower than 0.05 were considered an indication of significance.

“Biased information processing is an important marker Mitomycin C mouse of negative mood, and contributes to the development

of depression and anxiety disorders (Mathews & check details Macleod, 2005). A negative interpretation bias refers to the attribution of a negative compared to a benign or positive meaning to an ambiguous situation (Butler & Mathews, 1983); it is relative, and considering a lack of positive interpretation bias is also of interest. Negative interpretation bias has been associated with clinical depression and depressed mood (dysphoria) (Butler and Mathews, 1983, Lawson et al., 2002 and Rude et al., 2003). Cognitive models of depression suggest that negative interpretation bias – seeing one’s glass as perpetually half empty rather than half full – is critical to the maintenance of depressed mood (Beck,

1976). Promoting a less Interleukin-3 receptor negative interpretation bias is an important component of successful cognitive behavioral therapy (CBT) for depression (Hollon et al. 2005). CBM2 techniques have recently been developed to target such negative biases directly via computer-based training rather than face-to-face therapy (MacLeod, Koster, & Fox, 2009). For positive CBM interpretation bias (CBM-I), participants are trained to resolve situations that initially appear ambiguous in a benign/positive rather than negative way. CBM-I was initially developed in the context of anxiety disorders (e.g. Grey and Mathews, 2000 and Mathews and Mackintosh, 2000). A CBM-I procedure emphasising the use of mental imagery to simulate scenarios, has been developed to reduce vulnerability to depressed mood (Blackwell and Holmes, 2010 and Holmes et al., 2009). Experiments and treatments designed to modify interpretation bias would clearly benefit from tools to measure it. Perhaps surprisingly, the choice is currently limited; the measures include a physiological test – measuring the magnitude of blink reflex (from a puff of air to the eye) in response to ambiguous stimuli (Lawson et al. 2002) – and a behavioral test such as the Scrambled Sentences Task (Wenzlaff, Wegner, & Pennebaker, 1993). In the latter, participants are asked to make a sentence from a mixed sequence of words (under a cognitive load and constrained time).
