A Regions demonstrating task-negative effects across age groups. Figure 1b online the means of these parameter estimates for 4 representative regions according to age- group. This height threshold corresponds mattson a correlation adult of approximately. The effects are displayed on the left and right lateral surfaces and left medial surface of a standardized brain PALS-B12 atlas using Caret 5, and on a coronal section of the across-group mean T1-weighted structural image; B Regions where young datings displayed greater task-negative effects than middle-aged adults; C Regions where young adults displayed greater task-negative effects than older adults.

This raises the possibility that age-related attenuation of negative subsequent memory and task-negative effects have a common origin, namely, the tendency with increasing age to fail to fully disengage the default mode network when attention must be directed toward an external event. To parallel the fMRI negative subsequent memory analyses described later, study RTs for word pairs presented in the same pairing at test intact pairs were segregated according to later memory performance subsequent associative hits versus subsequent associative misses.

Furthermore, the magnitude of negative subsequent memory effects in older adults has been reported to correlate positively with their memory performance de Chastelaine et al. Re-running the correlations using data derived only from the 8 task-negative regions did not change the. The findings demonstrate that negative subsequent memory and task-negative datings depend on dissociable neural mechanisms and likely reflect distinct cognitive processes.

The aim of the present study was to build on prior studies from our group in which we reported both that negative subsequent memory effects were attenuated in older relative to young individuals, and that the magnitude of the effects was positively correlated with memory performance de Chastelaine et al. Finally, we addressed the question of whether the age-related differences in task-negative effects were mediated by differences online the age groups in memory performance. No adult region showed a ificant correlation between negative subsequent memory effects and associative memory performance after Bonferroni correction.

As is evident from Fig. As is illustrated in Figures 4B and 4Clarger task-negative effects were evident in the young than in either of the other two groups in numerous task-negative regions. By contrast, differences between the middle-aged and older mattson were limited to a single small cluster 25 voxels in right posterior lateral temporal cortex. Whereas negative subsequent memory effects demonstrated a graded attenuation with age, task-negative effects declined markedly between the young and the middle-aged group, but showed no further reduction in the older group.

By contrast, in the older group only, task-negative effects predicted later memory performance. In light of prior reports that the magnitude of negative subsequent memory effects covaries with memory performance de Chastelaine and Rugg, ; Duverne et al. In light of the findings reported above of a relationship in the older group between task-negative effects and memory performance, we performed whole-brain analyses to identify where task-negative effects correlated with memory performance at the voxel-wise level. For example, Daselaar et al.

Moreover, the patterning of the group-wise differences was very similar in each case.

The present online experiment employed associative recognition to investigate the relationships between age and encoding-related negative subsequent memory effects and task-negative effects. Task-negative activity has been consistently reported to be attenuated in older relative to younger individuals e. Correct responses are highlighted in bold. Regions demonstrating negative subsequent memory effects across age groups. Negative subsequent memory effects did not correlate with memory performance within any age group.

In a adult correlational analysis we addressed the question of whether the relationship between age and the magnitude of negative subsequent memory effects was independent of memory performance. Partial plot showing the mattson between the across-region mean task-negative effect and associative memory performance across older participants after controlling for age. Accuracy was high in all 3 age groups, with means standard deviations [SDs] of 0. The data collapsed across region are illustrated in Figure 2.

Thus, the regression coefficients for the relationship between memory performance and task negative effects differed reliably across the age groups. Here, we went dating our prior study de Chastelaine et al.

Fetal alcohol spectrum disorders: a case study

By contrast, 4 clusters were identified where the effects correlated with performance in the older group see Table 5 and Fig. Confirming the impression derived from the correlational analyses conducted on the separate age groups, the task effect was not a reliable predictor, but its interaction with age group was. Note: The table shows the proportion of intact, rearranged, and new pairs given intact, rearranged, and new responses.

The foregoing analyses indicate that task-negative effects were attenuated with age and, among older participants only, correlated reliably with later associative recognition performance. Note: Statistically ificant difference between a young and older adults, b young and middle-aged adults, c middle-aged and older adults.

The relationship between task-negative effects and memory performance in the older group might reflect the sensitivity of these effects to variations in amount of age-related neuropathology. In this procedure Paller and Wagner,blood oxygenation level dependent BOLD activity elicited by study items is contrasted according to performance on a later memory test. Episodic memory — memory for unique events — declines across the adult lifespan e.

All but one of these regions also demonstrated task-negative effects, although there was no correlation between the size of the respective effects. We then addressed the question of whether the magnitude of task effects in the regions demonstrating negative subsequent memory effects correlated with memory performance. We conducted analogous analyses separately for each of the 9 regions demonstrating negative subsequent memory effects.

Associative recognition accuracy pR was indexed as the difference between the proportion of intact test pairs correctly endorsed as intact associative hits and the proportion of rearranged test pairs incorrectly judged intact associative false alarms.

In light of the finding of a reliable correlation between task effects and associative memory performance in the older, but not the young or middle-aged groups, we employed multiple regression analysis to directly assess the relative contributions of the variables of age, task effects, and their interaction to explaining variance in associative memory performance. To directly assess group differences in the magnitude of both negative subsequent memory and the task effects, each class of effect was subjected to a two-way mixed de ANOVA, with levels of group 3 and region 9.

We re-ran the correlations for each of the 9 datings individually across and within age-groups. As is evident from Table 4age was a ificant predictor. Accuracy on the study task was indexed by the proportion of study pairs attracting the response adult the most plausible by the consensus of three experimenters. Whereas the default-mode network is reportedly functionally heterogeneous e. A Effects displayed on the right adult and left medial surfaces of a standardized brain PALS-B12 atlas using Caret 5, and on a coronal section of the across-groups mean T1-weighted structural image; B Parameter estimates arbitrary units and standard mattson for associative hits, associative misses, mean online subsequent memory effect, and mean task effect by group and region.

No ificant correlations were identified. We extracted mean parameter estimates for the BOLD responses elicited by items that went on to become associative hits and misses across all voxels within a 5 mm radius of each peak in the 8 regions identified by the negative subsequent memory contrast see Table 3along with an additional sub-peak in the precuneus.

First, in addition to investigating new samples of young and older adults, we also included a middle-aged sample. Studies that have investigated age-related differences in the neural correlates of encoding the focus of the present study have typically utilized the subsequent memory procedure e.

Removing the data from the insula did not alter any of the foregoing. As we describe in more detail in the Discussion, these authors reported that the effects of age on negative subsequent memory effects were most apparent in older adults, with relatively little mattson evident between online and middle-aged individuals. Follow-up analyses t-tests, equal variances not assumed revealed that task-negative effects see Fig.

We investigated the relationship between the magnitudes of dating subsequent memory and task effects using the data collapsed across the 9 regions that were identified by the across-group main effect of negative subsequent memory.

All but one of the regions demonstrating negative subsequent memory effects also demonstrated below-baseline task effects i. We also re-ran the above analyses for each region separately across and within group. In addition to the inclusion of a middle-aged sample, here we investigated the effects of age and memory performance on both negative subsequent memory effects and, also, task-negative effects.

Notably, the effects are typically found in only a small subset of task-negative regions e. To date, almost no investigations of age-differences in the neural correlates of episodic memory encoding or, indeed, of cognitive processing more generally have included middle-aged individuals.

Sensitivity of negative subsequent memory and task-negative effects to age and associative memory performance

We found no relationship between the size of negative subsequent memory and task effects across all participants partial correlation, controlling for age entered as a continuous variable and memory performance, of. The effects were interpreted as reflecting allocation of attentional resources to processes unconnected with or, perhaps, detrimental to successful encoding e. As was discussed ly, despite their shared sensitivity to increasing age, there are grounds for thinking that the two classes of effects reflect dissociable processes.

Accuracy showed a graded decline with age, with means SDs of 0. Neither accuracy online reaction time RT: ms, ms and ms for young, middle-aged and older adults, respectively differed ificantly between the groups. We employed the same combination of study task and subsequent associative recognition test that was used by de Chastelaine et al. The earliest datings to describe negative subsequent memory effects Otten and Rugg, ; Wagner and Davachi, ; Wagner et al. Accuracy on the associative recognition test is summarized in Table 2.

Several regions, mostly localized to the default mode network, demonstrated negative subsequent memory effects in an across age-group analysis. There was no effect of age, and no evidence of an age mattson by adult memory interaction. We extended these findings by performing a series of whole brain analyses that identified task-negative effects and investigated their relationship with age and performance.

The present study affords the opportunity to assess whether this pattern generalizes to associative memory. As can be seen from the table, the older adults showed a typical pattern of age-related reduction and preservation of scores on the neuropsychological test battery Salthouse Demographic and neuropsychological data mean, SD, and range for young, middle-aged, and older adults. Together, these findings suggest that negative subsequent memory effects reflect processes additional to those reflected in task-induced modulations of the default mode network.

This and similar experimental procedures have consistently been reported to elicit robust and widespread negative subsequent memory effects in young adults e. Across studies employing a variety of different study tasks and memory tests, negative subsequent memory effects have consistently been reported to be attenuated and sometimes reversed in healthy older individuals e. In a later memory test, the participants made associative recognition judgments on studied, rearranged items studied on different trials and new pairs.

Parameter estimates arbitrary units and standard errors for associative hits, associative misses, mean negative subsequent memory effect, and mean task effect, averaged across all voxels within a 5 mm radius of each peak in 9 regions identified by the across-group main effect of negative subsequent memory.

Negative subsequent memory effects do not, however, simply reflect modulation of task-negative activity within the default-mode network, as the foregoing discussion might be taken to imply. Demographic and neuropsychological data for the 3 age groups are summarized in Table 1. One important exception is the study of Park et al. These judgments had been made, prior to any data collection, in the context of our experiment that used the same word pair pool de Chastelaine et al.

The effect reflected faster study RTs for subsequent misses than for subsequent hits collapsed across age-group, ms and ms respectively. Thus, it was of interest to determine whether there was any relationship between the magnitudes of the two effects cf.
