Perceptual learning can develop over extended periods, with slow, at times sleep-dependent, improvement seen several days after training. As a result, performance can become more automatic, that is, less dependent on voluntary attention. This study investigates whether the brain correlates of this enhancement of automaticity are sleep-dependent. Event-related potentials produced in response to complex auditory stimuli were recorded while subjects' attention was focused elsewhere. We report here that following training on an auditory discrimination task, performance continued to improve, without significant further training, for 72 hr. At the same time, several event-related potential components became evident 48–72 hr after training. Posttraining sleep deprivation prevented neither the continued performance improvement nor the slow development of cortical dynamics related to an enhanced familiarity with the task. However, those brain responses associated with the automatic shift of attention to unexpected stimuli failed to develop. Thus, in this auditory learning paradigm, posttraining sleep appears to reduce the voluntary attentional effort required for successful perceptual discrimination by facilitating the intrusion of a potentially meaningful stimulus into one's focus of attention for further evaluation.

Alcohol dependence (AD) presents cognitive control deficits. Event-related potential (ERP) P300 reflects cognitive control-related processing. The aim of this study was to investigate whether cognitive control deficits are a trait biomarker or a state biomarker in AD. Participants included 30 AD patients and 30 healthy controls (HCs). All participants were measured with P300 evoked by a three-stimulus auditory oddball paradigm at a normal state (time 1, i.e., just after the last alcohol intake) and abstinence (time 2, i.e., just after a 4-week abstinence). The results showed that for P3a and P3b amplitude, the interaction effect for group × time point was significant, the simple effect for group at time 1 level and time 2 level was significant, and the simple effect for time point at AD group level was significant; however, the simple effect for time point at HC group level was not significant. Above results indicated that compared to HCs, AD patients present reductions of P3a/3b amplitude, and after 4-week alcohol abstinence, although P3a/3b amplitudes were improved, they were still lower than those of HCs. For P3a and P3b latencies, no significant differences were observed. These findings conclude that AD patients present cognitive control deficits that are reflected by P3a/3b and that cognitive control deficits in AD are trait- and state-dependent. The implication of these findings is helpful to understand the psychological and neural processes for AD, and these findings suggest that improving the cognitive control function may impact the treatment effect for AD.

Demands on directed attention can result in attentional fatigue, inhibiting our ability to voluntarily direct attention to important features of our surroundings. Inherently fascinating environments, such as nature, have been shown to promote recovery of attention while environments that do not possess these qualities, such as urban settings, do not promote recovery. Previous research has demonstrated benefits associated with exposure to nature including improved physiological and mental health, and increased performance in attention tasks. The goal of the current research was to utilise the P3 cognitive component of the event-related potential (ERP), which has been shown to be modulated by attentional demands, as a cognitive marker indicative of attentional recovery. We measured electroencephalography (EEG) data while participants simultaneously completed an auditory oddball task and viewed images of nature and urban scenes. A replication was attempted using the Attention Network Task (ANT) to show that the restorative qualities of nature influence executive, voluntary attention rather than involuntary attention. Contrary to our predictions, no significant differences in the P3 component were observed and we were unable to successfully replicate previous research using the ANT. However, significant differences were found in earlier EEG components which suggest that the auditory stimuli are being processed differently depending on the scene displayed. EEG differences were also found following presentation of the scenes themselves and are consistent with previous research related to differences in scene complexity, contrast, and other characteristics. Further research needs to focus on these auditory and visual EEG differences to better understand neural correlates associated with the restorative benefits of natural environments.
