A novel scoring protocol reveals age-related differences in abstract compared to concrete thinking in cued autobiographical remembering.

Human imagination has garnered growing interest in many fields. However, it remains unclear how to characterize different forms of imaginative thinking and how imagination differs between young and older adults. Here, we introduce a novel scoring protocol based on recent theoretical developments in the cognitive neuroscience of imagination to provide a broad tool with which to characterize imaginative thinking.

Shape of the past: Revealing detail arcs while narrating memories of autobiographical life events across the lifespan.

Humans can remember past autobiographical events through extended narratives. How these narrated memories typically unfold, however, remains largely unexplored. We evaluated how autobiographical memory details typically come together in a sample of 235 healthy young, middle-aged, and older adults.

Creative minds at rest: Creative individuals are more associative and engaged with their idle thoughts.

Despite an established body of research characterizing how creative individuals explore their world, relatively little is known about how such individuals navigate their , especially in unstructured contexts such as periods of awake rest. Across two studies, the present manuscript tested the hypothesis that creative individuals are more engaged with their idle thoughts and more associative in the dynamic transitions between them. Study 1 captured the real-time conscious experiences of 81 adults as they voiced aloud the content of their mind moment-by-moment across a 10-minute unconstrained baseline period.

Speaking Well and Feeling Good: Age-Related Differences in the Affective Language of Resting State Thought.

Unlabelled: Despite the prevalence and importance of resting state thought for daily functioning and psychological well-being, it remains unclear how such thoughts differ between young and older adults. Age-related differences in the affective tone of resting state thoughts, including the affective language used to describe them, could be a novel manifestation of the positivity effect, with implications for well-being. To examine this possibility, a total of 77 young adults ( = 24.

Direct access to specific autobiographical memories is lower in healthy middle-aged to older adult Apolipoprotein E ε4 carriers compared to non-carriers.

Recent research suggests that the retrieval of autobiographical memories among cognitively healthy middle-aged and older adults is sensitive to the Apolipoprotein E ε4 (APOE4) allele, a genetic marker that increases the risk of Alzheimer's disease (AD) dementia. However, whether the APOE4-associated alteration in autobiographical memory retrieval encompasses rapid (i.e.

Retrieving autobiographical memories in autobiographical contexts: are age-related differences in narrated episodic specificity present outside of the laboratory?

The Autobiographical Interview, a method for evaluating detailed memory of real-world events, reliably detects differences in episodic specificity at retrieval between young and older adults in the laboratory. Whether this age-associated reduction in episodic specificity for autobiographical event retrieval is present outside of the laboratory remains poorly understood. We used a videoconference format to administer the Autobiographical Interview to cognitively unimpaired older adults (N = 49, M = 69.

Mindfulness-based cognitive therapy neurobiology in treatment-resistant obsessive-compulsive disorder: A domain-related resting-state networks approach.

Mindfulness-based cognitive therapy (MBCT) stands out as a promising augmentation psychological therapy for patients with obsessive-compulsive disorder (OCD). To identify potential predictive and response biomarkers, this study examines the relationship between clinical domains and resting-state network connectivity in OCD patients undergoing a 3-month MBCT programme. Twelve OCD patients underwent two resting-state functional magnetic resonance imaging sessions at baseline and after the MBCT programme.

Efficacy and fMRI-based response predictors to mindfulness-based cognitive therapy in obsessive-compulsive disorder: Study protocol for a randomised clinical trial.

Background: Around 40-50% of patients with obsessive-compulsive disorder (OCD) suffer from obsessions and compulsions after receiving first-line treatments. Mindfulness-based cognitive therapy (MBCT) has been proposed as a reasonable augmentation strategy for OCD. MBCT trains to decentre from distressful thoughts and emotions by focusing on them voluntarily and with consciousness.

A dorsomedial prefrontal cortex-based dynamic functional connectivity model of rumination.

Rumination is a cognitive style characterized by repetitive thoughts about one's negative internal states and is a common symptom of depression. Previous studies have linked trait rumination to alterations in the default mode network, but predictive brain markers of rumination are lacking. Here, we adopt a predictive modeling approach to develop a neuroimaging marker of rumination based on the variance of dynamic resting-state functional connectivity and test it across 5 diverse subclinical and clinical samples (total n = 288).

Dreams share phenomenological similarities with task-unrelated thoughts and relate to variation in trait rumination and COVID-19 concern.

While recent neurocognitive theories have proposed links between dreams and waking life, it remains unclear what kinds of waking thoughts are most similar in their phenomenological characteristics to those of dreams. To investigate this question and examine relevance of dreams to significant personal concerns and dispositional mental health traits, we employed ecological momentary assessment and trait questionnaires across 719 young adults who completed the study during the COVID-19 pandemic, a time marked by considerable societal concern. Across the group and at the level of individual differences, dreams showed the highest correspondence with task-unrelated thoughts.

Past and future episodic detail retrieval is reduced among clinically normal older adults at higher genetic risk for late-onset Alzheimer's disease.

Objective: Remembering and imagining personal events that are rich in episodic (i.e., event-specific) detail is compromised in older adults who have mild cognitive impairment, a known risk factor for Alzheimer's disease dementia.

Functional connectivity with medial temporal regions differs across cultures during post-encoding rest.

Connectivity of the brain at rest can reflect individual differences and impact behavioral outcomes, including memory. The present study investigated how culture influences functional connectivity with regions of the medial temporal lobe. In this study, 46 Americans and 59 East Asians completed a resting state scan after encoding pictures of objects.

Task-unrelated thought increases after consumption of COVID-19 and general news.

Task-unrelated thoughts (TUTs) are frequent distractions from our everyday tasks, which can reduce productivity and safety during task performance. This necessitates the examination of factors that modulate TUT occurrence in daily life. One factor that has previously been implicated as a source of TUT is personally salient concerns.

Associations Between Age and Resting State Connectivity Are Partially Dependent Upon Cardiovascular Fitness.

Previous research suggests a marked impact of aging on structural and functional connectivity within the frontoparietal control network (FPCN) and default mode network (DMN). As aging is also associated with reductions in cardiovascular fitness, age-related network connectivity differences reported by past studies could be partially due to age-related declines in fitness. Here, we use data collected as part of a 16-week exercise intervention to explore relationships between fitness and functional connectivity.

Variation is the Norm: Brain State Dynamics Evoked By Emotional Video Clips.

For the last several decades, emotion research has attempted to identify a "biomarker" or consistent pattern of brain activity to characterize a single category of emotion (e.g., fear) that will remain consistent across all instances of that category, regardless of individual and context.

Tormenting thoughts: The posterior cingulate sulcus of the default mode network regulates valence of thoughts and activity in the brain's pain network during music listening.

Many individuals spend a significant amount of their time "mind-wandering". Mind-wandering often includes spontaneous, nonintentional thought, and a neural correlate of this kind of thought is the default mode network (DMN). Thoughts during mind-wandering can have positive or negative valence, but only little is known about the neural correlates of positive or negative thoughts.
