Differential activity related to the contrast inter-item binding (object/object vs. object/colour + object/location).
<p>All activations are corrected for multiple comparisons (FDR<0.05).</p
General activation related to the delay period collapsed over all trials against a low level visual fixation baseline.
<p>All reported activations are whole brain corrected for multiple comparisons (FDR<0.05).</p
Taxonomy of types of relational memory, distinguishing intra-item binding (objects and their features that can be either intrinsic or extrinsic) and inter-item binding (two unrelated items that have highly similar characteristicsâwithin-domainâor have less overlap with respect to stimulus characteristicsâbetween-domain).

Mean number of trials (+SD) separated for the factors distraction and subsequent memory.

Behavioral results.
<p>Item recognition scores (dâ) for schema-congruent memories were enhanced only after consolidation (A), while schema-congruent associative memory scores (% correct) were enhanced already immediately after encoding and this effect persisted during time (B). Panels C and D show the congruency effect for both these memory measures over time, where the congruency effect on memory is found to increase for item recognition (C), but not for associative memory (D).</p

Brain regions activated in associative memory formation (Association remembered>Association forgotten).
<p>Sagittal view (<b><i>left</i></b>) and coronal view (<b><i>right</i></b>) show the activation in the left hippocampus (MNI -21 -9 -15, SVC, <i>p</i>â=â0.029). Images are thresholded at <i>p</i><0.001 uncorrected, for displaying purposes. L, left; R, right.</p
Bar graphs of the results of the delayed-match-to sample (WM) task.
<p>(a) Hit â False Alarm Rates for pairs consisting of one neutral and either another neutral or a low- or high arousal picture. (b) Corrected Recognition when considering Valence levels. Particularly pairs containing a low-arousal positive picture were more likely to be correctly remembered. Error bars represent the standard error of mean.</p
Experimental paradigm.
<p>Encoding task inside the scanner (<b><i>a</i></b>) and the post-scan memory tests (<b><i>b</i></b>, <b><i>c</i></b>). <b><i>a</i></b>, <b><i>top</i></b>, In each trial, the image of an object was presented first, followed by a fixation cross, the distraction task, and the face. <b><i>a</i></b>, <b><i>bottom</i></b>, The distraction task was either a simple visuo-motor control task (low distraction condition) or a working memory task (high distraction condition). In both tasks, six letters were sequentially presented and subjects had to indicate whether the final letter of each sequence was identical to one of the previous five letters. <b><i>b</i></b>, Face recognition memory test. Subjects had to make an old-new judgment on each sequentially presented face by a confidence rating on a six-point scale. <b><i>c</i></b>, The associative memory test. Subjects had to connect the studied object-face pairs by lines and add a confidence rating. Note: in this figure, the actual face stimuli are replaced by smiley, because of unclear copyright status.</p
Bar graphs of the results of the single-item LTM task.
<p>(a) âHit â False Alarm Ratesâ for neutral, low-arousal and high-arousal items in the single item LTM task. No significant differences were found. (b) Corrected Recognition when considering Valence levels. No statistically reliable differences were found.</p
