Article Abstract
Prospective memory (PM) is future-oriented memory that requires planning ahead, maintaining intention, recognizing cues, and responding correctly in time. PM tasks are susceptible to personality traits such as impulsivity. Barratt holds that impulsivity can be divided into three dimensions: non-planning impulsiveness, attentional impulsiveness, and motor impulsiveness. The characteristics of impulsive individuals in these three areas may contribute to their PM disadvantage. This study explored the impact of impulsivity on PM. Experiment 1 investigated the influence of impulsivity on PM under different attention load conditions. The results showed that the impulsive group was inferior only under the condition of high attention load; this effect was mainly related to the characteristics of attentional impulsiveness and motor impulsiveness. Experiment 2 explored the effect of impulsivity on PM under different response types, which were divided into delayed response condition and non-delayed response condition. The results showed that delayed response eliminated the impulsive individuals' deficiency in PM performance. This study focused on the influencing factors and processing mechanism by which impulsivity affects PM. It also found an effective method to improve the PM performance of impulsive individuals. These results have both theoretical and practical significance.

BackgroundThe production of verbal tenses is impaired in people with Alzheimer's disease (AD), as shown by several studies focusing on time reference and using sentence completion tasks. However, there is currently a limited understanding of how tense is produced in discourse with this disease. Discourse is interesting as it involves building a mental representation of the event to be narrated with its temporal framework and translating this framework into language using tense.

Background: Sleep duration plays a crucial role in cognitive health and is closely linked to cognitive decline. However, the relationship between sleep duration and cognitive function in the Chinese population remains poorly understood.
Objective: This study aims to evaluate the association between sleep duration and cognitive function among middle-aged and older adults in China.

It has been suggested that episodic memory relies on the well-studied machinery of spatial memory. This influential notion faces hurdles that become evident with dynamically changing spatial scenes and an immobile agent. Here I propose a model of episodic memory that can accommodate such episodes via temporal indexing.

Our understanding of how the medial temporal lobe (MTL) contributes to human cognition has advanced enormously over the past half a century. My work in the 1990s characterizing the role of recollection and familiarity processes in episodic memory led me to study the MTL's role in these two memory processes. In the current paper, I provide a personal commentary in which I describe the motivating ideas, as well as the invaluable impact of mentors, colleagues, and students that led to a series of studies showing that conscious recollection is critically dependent on the hippocampus, whereas familiarity-based judgments are dependent on regions such as the perirhinal cortex.

Study Objectives: Research linking children's sleep to cognitive outcomes is inconsistent and has largely focused on one aspect of sleep, such as duration, rather than measuring multiple dimensions of sleep health. We hypothesized that children's sleep health would be positively associated with inhibitory control and cognitive functioning.
Method: We cross-sectionally assessed 1595 participants (ages 7-11) from the Environmental influences on Child Health Outcomes cohort using the NIH Toolbox Cognition Battery, Environmental influences on Child Health Outcomes Sleep Health of Children and Adolescents questionnaire, and Patient Reported Outcome Measurement Information System Sleep Disturbance/Sleep-related Impairment instruments.
