This research is an integrative review of scientific evidence differentiating between cognitive reserve (CR) and brain maintenance concepts. Thus, we have examined how CR socio-behavioral proxies (i.e. education, occupational attainment, and leisure activities) may help to cope with age-related cognitive decline and negative consequences of brain pathology. We also analyze lifestyle factors associated with brain maintenance or the relative absence of change in neural resources over time. Medline and Web of Science databases were used for the bibliographic search in the last 20 years. Observational cohort studies were selected to analyze the effect of different CR proxies on cognitive decline, including dementia incidence, whereas studies employing functional neuroimaging (fMRI) were used to display the existence of compensation mechanisms. Besides, structural MRI studies were used to test the association between lifestyle factors and neural changes. Our findings suggest that education, leisure activities, and occupational activity are protective factors against cognitive decline and dementia. Moreover, functional neuroimaging studies have verified the existence of brain networks that may underlie CR. Therefore, CR may be expressed either through a more efficient utilization (neural reserve) of brain networks or the recruitment of additional brain regions (compensation). Finally, lifestyle factors such as abstaining from smoking, lower alcohol consumption, and physical activity contributed to brain maintenance and were associated with the preservation of cognitive function. Advances in multimodal neuroimaging studies, preferably longitudinal design, will allow a better understanding of the neural mechanisms associated with the prevention of cognitive decline and preservation of neural resources in aging.Attention abilities rest on the coordinated interplay of multiple components. One consequence to this multifaceted account is that selection processes likely intersect with perception at various junctures. Drawing from this overarching view, the current research examines how different forms of visuospatial attention influence various aspects of conscious perception, including signal detection, signal discrimination, visual awareness, and metacognition. In this effort, we combined a double spatial cueing approach, where stimulus- and goal-driven orienting were concurrently engaged via separate cues, with Type I and Type II signal detection theoretic frameworks through five experiments. Consistent with the modular view of visuospatial attention, our comprehensive assessment reveals that stimulus- and goal-driven orienting operate independently of each other for increasing perceptual sensitivity and reducing the decision bound. Conversely, however, our study shows that both forms of orienting hardly influence visual awareness and metacognition once perceptual sensitivity is accounted for. Our results therefore undermine the idea that attention directly interfaces with subjective aspects of perception. Instead, our findings submit a general framework whereby these attention modules indirectly impact visual awareness and metacognition by increasing perceptual evidence and decreasing the decision bound.

One critical question is how observers learn to avoid capture, particularly in situations where they receive no direct feedback about attentional performance. One possibility is that individuals have some level of introspective awareness of capture when it occurs. Once capture is detected, participants then adjust performance strategies to avoid subsequent attentional capture. It is currently unclear, however, if observers have any introspective awareness of attentional capture when it occurs. In the current study, participants attempted to locate a target shape and ignore a salient distractor. On half of trials, participants were then asked to classify whether their first eye movement was misdirected to the singleton distractor on that trial. The results demonstrated that participants clearly had some level of introspective awareness of attentional capture Oculomotor capture effects were much larger on “capture” report trials than on “no capture” report trials. Interestingly, there was no evidence that awareness of oculomotor capture prevented subsequent capture by salient items. Future research is needed to definitively determine whether metacognitive awareness can be used as a training tool to prevent capture.

However, the effectiveness of a dual-task paradigm is greatly reduced when studying working memory, because it is hard to distinguish dual-task interference due to shared executive processes from that due to shared memory storage. In the present study, we provided convergent evidence that dual-task cost in recall precision is a specific indicator of evaluating the interference across working memory representations that is irrelevant to executive processing. Experiments 1 and 2 showed that when two working memory tasks were performed concurrently, dual-task cost in recall precision showed up only if stimuli in the two tasks shared overlapping representational space. Experiments 3 and 4 found that when a working memory task was conducted concurrently with an attention-consuming task, no dual-task cost in recall precision showed up as long as stimuli in the two tasks did not share overlapping representational space. Experiment 5 further revealed that if a single-object tracking task is conducted while holding both color and location information in working memory, the tracking task would specifically affect the recall precision of the retrieved location (but not of the retrieved color). The present results suggested that dual-task cost in recall precision may provide a convenient and specific index for evaluating interference across working memory storage.
