Objectives: We aimed to understand how adverse childhood experiences (ACEs) correlated with undergraduates’ examination performance, while looking at the contributions of attentional control and resilience. Methods: Students aged 18–25 years were recruited from first-year Psychology classes (Total N = 488). ACE scores, as well as the Attention Cont...

Objectives Chronotype impacts our state at a given time of day, however, chronotype is also heritable, trait-like, and varies systematically as a function of age and sex. However, only a handful of studies support a relationship between chronotype and trait-like cognitive abilities (i.e., intelligence), and the evidence is sparse and inconsistent b...

OBJECTIVES: The current study presents a systematic review of the evidence for mindfulness-based interventions (MBIs) as a form of neuropsychological rehabilitation, a holistic approach to treatment that may be particularly well suited to persons with neurological illness and injury. METHODS: Following the PRISMA guidelines for systematic reviews,...

The purpose of this study was to examine whether a virtual reality plus neurofeedback (VR+NF) meditation experience (experimental condition) was more effective than a standard guided audio-only meditation (control condition) in improving mood in one hundred healthcare workers. Data collection occurred in a hospital setting between October, 2020 and...

Research and design of virtual reality technologies with mental-health focused applications has increased dramatically in recent years. However, the applications and psychological outcomes of augmented reality (AR) technologies still remain to be widely explored and evaluated. This is particularly true for the use of AR for the self-management of s...

Human sleep can be broadly categorized as rapid eye movement (REM) and non-REM (NREM) sleep according to the electrophysiological features and oscillations that characterize these distinct states. The most dramatic changes that occur to sleep are observed over the course of the life span. With aging, the neural oscillations of sleep may provide ins...

Objectives Interest in neurofeedback therapies (NFTs) has grown exponentially in recent years, encouraged both by escalating public interest and the financial support of health care funding agencies. Given NFTs’ growing prevalence and anecdotally reported success in treating common effects of acquired brain injury (ABI), a systematic review of the...

Objective The current study was intended to provide a rigorous systematic review of the evidence to date regarding the efficacy of mindfulness-based interventions (MBIs) in persons with neurologic illness/injury, a form of treatment that may be particularly well suited to the rehabilitation context due to its holistic approach. Data Selection The...

While previous research has established that virtual reality (VR) can be successfully used in the treatment of anxiety disorders, including phobias and PTSD, no research has examined changes in brain patterns associated with the use of VR for generalized anxiety management. In the current study, we compared a brief nature-based mindfulness VR exper...

Introduction Periodic limb movements (PLMs) during sleep increase with age and are associated with striatal neurodegeneration and dopamine deficiency. Limb movements are often associated with disruptions to non-rapid eye movement (NREM) sleep. Motor skill memory consolidation recruits the striatum and learning-dependent striatal activation is assoc...

Sleep facilitates the consolidation (i.e., enhancement) of simple, explicit (i.e., conscious) motor sequence learning (MSL). MSL can be dissociated into egocentric (i.e., motor) or allocentric (i.e., spatial) frames of reference. The consolidation of the allocentric memory representation is sleep-dependent, whereas the egocentric consolidation proc...

Sleep spindles-short, phasic, oscillatory bursts of activity that characterize non-rapid eye movement sleep-are one of the only electrophysiological oscillations identified as a biological marker of human intelligence (e.g., cognitive abilities commonly assessed using intelligence quotient tests). However, spindles are also important for sleep main...

Previous work has demonstrated an influence of the respiratory cycle and, more specifically, rhythmic nasal inspiration for the entrainment of slow oscillations in olfactory cortex during ketamine-xylazine anesthesia. This respiratory entrainment has been suggested to occur more broadly during slow-wave states (including sleep) throughout the foreb...
