Recognition accuracy (+S.E.M.) for the controls and the Alzheimer group for the toys and non-toys placed at decision points or non-decision points.

<p>Recognition accuracy (+S.E.M.) for the controls and the Alzheimer group for the toys and non-toys placed at decision points or non-decision points.</p

Stills from the virtual museum route showing a toy placed at a non-decision point (A) and a non-toy at a decision point (B), and schematic overview of the recognition trials (C).

<p>Participants had to indicate whether the presented object was shown in the movie or not by button press.</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 characteristics–within-domain–or have less overlap with respect to stimulus characteristics–between-domain).

Bar graphs of the results of the delayed-match-to sample (WM) task.

<p>(a) Hit – 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

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

Hit (HR), false alarm rates (FAR), the sensitivity measure A’, and Proportion Correct (PR) as a function of task and condition.

Bar graphs of the results of the single-item LTM task.

<p>(a) ‘Hit – False Alarm Rates’ 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

Bar graphs of the results of the associative LTM task.

<p>(a) Proportion Correct for pairs consisting of one neutral picture and another neutral or a low- or high arousal picture. Pairs consisting of high-arousal picture were less likely to be remembered in the LTM task. (b) Proportion Correct when considering Valence levels. Particularly pairs containing high-arousal positive picture were less likely to be remembered. Error bars represent the standard error of mean.</p
