Figure 4

Figure 4. From: Impaired context processing as a potential marker of psychosis risk state.

HC participants (n=35) show increased DLPFC activation bilaterally during Cue B trials, which require higher levels of cognitive control, but CHR (n=25) and FE (n=35) participants do not.

Figure 1

Figure 1. From: Impaired context processing as a potential marker of psychosis risk state.

AXCPT Task Parameters: Subjects make a target response to probe X, only when it follows the cue A. Non-target BX trials require increased cognitive control to prevent error.

Figure 3. From: Impaired context processing as a potential marker of psychosis risk state.

Between-group activation maps contrasting HC participants to FE and CHR groups at an uncorrected threshold of p<0.01 for illustration purposes. Regions surviving FWE correction are outlined in .

Figure 2

Figure 2. From: Impaired context processing as a potential marker of psychosis risk state.

CHR participants (n=25) show a specific deficit in cognitive control on the AXCPT, as indicated by higher BX errors (A) and lower d’ context (B), when compared to HC individuals (n=35), in a manner that is similar to FE individuals (n=35)

Figure 5

Figure 5. From: Impaired context processing as a potential marker of psychosis risk state.

In CHR individuals, the difference in activation (mean beta value) from Cue A to Cue B trials, which require higher levels of cognitive control, shows a pattern of association with improved ability to effectively process context on the AXCPT (d’-context, with 95% Confidence Intervals for the mean).
