Summary: Older adults show an enhanced N170 amplitude during the visualization of facial expressions of emotion. This effect is not specific to facial stimuli and is not modulated by own-age faces. The increased N170 amplitude in older adults may reflect a higher ambiguity of older faces due to age-related changes in their physical features, while the decreased P250 amplitudes for older faces may reflect a reduced processing of the emotional content of these faces.

Summary: The direction of eye gaze provides important information about others' attention and intentions. This review examined the sensitivity of the event-related potential component N170 to gaze direction. The findings suggest that N170 sensitivity to gaze direction is influenced by factors such as deviated faces, dynamic stimuli, and explicit tasks related to gaze or face processing.

Summary: The study examined how different components of event-related potential (ERP) to threat-related facial expressions are modulated by attentional conditions and interindividual differences in trait anxiety. The N170 response to fearful faces was found to increase regardless of perceptual load and spatial attention conditions, while the EPN response to fearful faces only increased during low load and spatial attention to the face. The results question the hypothesis of a general hypersensitivity toward fearful expressions in anxious individuals.

Summary: This study investigated the temporal processes of attentional modulation under high perceptual load using a perceptual load paradigm, considering perceptual load, distractor-target compatibility, and eccentricity. The results showed that high perceptual load significantly reduced attentional distraction from peripheral distractors, and the event-related potential results revealed shorter P2 latencies for peripheral distractors compared to central distractors under high perceptual load. The P3 component reflected a suppressed compatibility effect with increasing load. These findings suggest that the P2 and P3 components capture different aspects of attentional processing modulated by load and that the response patterns of selective attention modulated by perceptual load are influenced by eccentricity. Our electrophysiological evidence confirms the behavioral findings and indicates the neural mechanisms of attentional modulation.

Summary: The C1 event-related potential (ERP) captures the earliest stage of feedforward processing in the primary visual cortex (V1). There is a debate on whether top-down selective attention can modulate the C1. Results from a systematic review and meta-analysis suggest that attention has a moderate effect on the C1, with larger C1 amplitude for attended visual stimuli.

Summary: The Stroop effect is a well-documented phenomenon that demonstrates both interference and facilitation effects. Different versions of the Stroop task have been created for various purposes, serving as a measure of attention, inhibitory control, and executive functions. The implementation of eStroop, a new digital version based on verbal responses, confirms the Stroop effect and provides baseline data for future research and clinical testing, while offering insights into differences and similarities with other recent versions of the task.

Summary: This study examined how people update their beliefs about animal minds based on informative clues. The findings showed that participants tended to shift their beliefs too far when presented with evidence suggesting animals do not have minds, but did not shift far enough when presented with evidence suggesting animals do have minds. This effect was attenuated when humans were the targets of belief.

Summary: In nine experiments, it was found that people's judgments about animals' mental capacities are influenced by biases of anthropomorphism or mind-denial. These biases are influenced by individuals' dietary choices and can affect beliefs about animal minds. This research demonstrates that memories concerning animals' minds can deviate from reality and contribute to biased evaluations of their mental capacities.

Summary: This study explores the effects of prolonged mask usage on the human brain by analyzing EEG and physiological parameters. The results show that the mean EEG spectral power in alpha, beta, and gamma sub-bands of individuals wearing masks is smaller than those without masks. The performances on cognitive tasks and oxygen saturation level differ between the two groups, while blood pressure, body temperature, and heart rate are similar. The analysis also reveals that the occipital and frontal lobes exhibit the greatest variability in channel measurements.
