The default mode network supports a variety of mental operations such as semantic processing, episodic memory retrieval, mental time travel and mind-wandering, yet the commonalities between these functions remains unclear. One possibility is that this system supports cognition that is independent of the immediate environment; alternatively or additionally, it might support higher-order conceptual representations that draw together multiple features. We tested these accounts using a novel paradigm that separately manipulated the availability of perceptual information to guide decision-making and the representational complexity of this information...

Post-traumatic stress disorder (PTSD) is characterized by impairments in mnestic functions, especially in the domain of episodic memory. These alterations might affect different aspects of episodic memory functioning. Here we tested PTSD patients and healthy controls (matched for age, sex and education) in a newly developed virtual reality episodic memory test (VR-EMT), a test for mental time travel, episodic future thinking, and prospective memory (M3xT). In a cross-validation experiment, their performance was further evaluated in the Rivermead Behavioral Memory Test (RBMT)...

REVIEW
Nicola S Clayton, Clive Wilkins
In this paper we highlight seven myths about memory, which centre around the fact that memories, as we experience them, are not only about the past, they are also prospective. Although episodic memory provides the template for future scenarios, it can be reassessed each time it is recalled, and in part is dependent on the sequence in which events unfold. We explore seven myths about memory, and the relationship between memory and experience. We refer to 'The Moustachio Quartet', a series of novels, which highlight themes and ideas relevant to our argument, and 'The Creatures in the Night', a picture book of paintings that explore the passage of time...

BACKGROUND: Low and middle income countries face many challenges in meeting their populations' mental health care needs. Though family caregiving is crucial to the management of severe mental health disabilities, such as schizophrenia, the economic costs borne by family caregivers often go unnoticed. In this study, we estimated the household economic costs of schizophrenia and quality of life of family caregivers in Ghana. METHODS: We used a cost of illness analysis approach...

Previous studies have revealed that preschoolers selectively allocate their resources based on their social relationship with recipients such as friendship. In this investigation, we investigated how expectations about recipients' prosociality and the ability of future thinking relate to the selective allocation of resources. In Study 1, participants aged 3.5-6 years chose how to allocate resources from two ways (selfish allocation, where only the participants could receive stickers, and equal allocation, where the participants and recipients receive get the same number of stickers) in costly and non-costly situations with three recipients (friend, peer, and stranger)...

Spatial information is tightly intertwined with temporal and valence-based information. Namely, "past" is represented on the left, and "future" on the right, along a horizontal mental timeline. Similarly, right is associated with positive, whereas left is negative. We developed a novel task to examine the effects of emotional valence and temporal distance on mental representations of time. We compared positivity biases, where positive events are positioned closer to now, and right hemisphere emotion biases, where negative events are positioned to the left...

Mental time travel refers to the ability to recall a past event and imagine the future. Some researchers claim that this ability is unique to humans, while others argue that nonhuman animals also possess this ability. A study on apes by using eye-tracking revealed that chimpanzees and bonobos can remember a single event for 24 hours, suggesting that they possess at least some elements of mental time travel.

We examined patients with mental space navigation or mental time travel disorder to identify regions in the brain that may play a critical role in mental time travel in terms of clinical neuropsychology. These regions included the precneus, posterior cingulate gyrus, retrosplenial cortex, and hippocampus, as well as the orbitofrontal cortex: the anterior and posterior medial areas were both shown to be important in this process. Further studies are required to define whether these form a network for mental time travel...

OBJECTIVES: This study explored school start times (SST) in relation to sleep duration and adherence to guidelines among Canadian youth. METHODS: Using Year 4 (2015/2016) data from the Cannabis, Obesity, Mental health, Physical activity, Alcohol use, Smoking, and Sedentary behaviour (COMPASS) study, the sample included 35,821 grade 9-12 students at 78 secondary schools in Ontario and Alberta, Canada. Random intercepts models tested student-reported sleep duration and whether students met sleep recommendations, as a function of SST, controlling for student- (race/ethnicity, grade, sex, travel mode to school) and school-level (school-area urbanicity and median household income) correlates...

AIM: to explore experiences of stigma in people with inflammatory bowel disease. BACKGROUND: Diarrhoea, urgency and incontinence are common symptoms in inflammatory bowel disease. Social rules stipulate full control of bodily functions in adulthood: poor control may lead to stigmatisation, affecting patients' adjustment to disease. Disease-related stigma is associated with poorer clinical outcomes but qualitative evidence is minimal. DESIGN: An interpretive (hermeneutic) phenomenological study of the lived experience of stigma in inflammatory bowel disease...

BACKGROUND: Posttraumatic stress disorder (PTSD) is a prevalent mental health issue among veterans. Access to PTSD treatment is influenced by geographic (ie, travel distance to facilities), temporal (ie, time delay between services), financial (ie, eligibility and cost of services), and cultural (ie, social stigma) barriers. OBJECTIVE: The emergence of mobile health (mHealth) apps has the potential to bridge many of these access gaps by providing remote resources and monitoring that can offer discrete assistance to trauma survivors with PTSD and enhance patient-clinician relationships...

Mental time travel (MTT) allows navigation into the past, the future, and the minds of others, and it subserves future-oriented decision-making. Impaired MTT has been associated with a tendency to over-rely on the present, which is a characteristic of addictive behaviors. We here discuss the possible relationship between impaired autographical memory, future-oriented MTT, shortened time horizons, suboptimal social cognition, and poor decision-making in individuals with drug and gambling use disorders. We elaborate on how impaired MTT could compromise the process of change in addiction recovery and the effectiveness of psychotherapy...

Research suggests that odors may serve as a potent cue for autobiographical retrieval. We tested this hypothesis in Alzheimer's disease (AD) and investigated whether odor-evoked autobiographical memory is an involuntary process that shares similarities with music-evoked autobiographical memory. Participants with mild AD and controls were asked to retrieve two personal memories after odor exposure, after music exposure, and in an odor-and-music-free condition. AD participants showed better specificity, emotional experience, mental time travel, and retrieval time after odor and music exposure than in the control condition...

Mental Time Travel (MTT) is the ability of individuals to project themselves to the past or to the future. Studies have shown that schizophrenia (SZ) patients are impaired in MTT. The present study aimed to examine whether MTT in patients with SZ can be improved through Life Review Therapy. Fifty patients with SZ were randomly assigned to the training (SZ-training) or control (SZ-control) group. Whereas the SZ-training group received four-week Life Review Therapy in addition to conventional treatment, the SZ-control group only received conventional treatment...

Background: Travel medicine research has remained relatively unchanged in the face of rapid expansion of international travel and is unlikely to meet health challenges beyond infectious diseases. Our aim was to identify the range of health outcomes during travel using real-time monitoring and daily reporting of health behaviours and outcomes and identify traveller subgroups who may benefit from more targeted advice before and during travel. Methods: We recruited a prospective cohort of travellers ≥ 18 years and planning travel to Thailand for <5 weeks from the travel clinics in Zurich and Basel (Switzerland)...

Background: Severe mental illness occurring abroad is a difficult situation for patients, their families, and for the local medical community. Patients with mental problem are doublely stigmatized due to their mental illness and because they are foreigners in an unfamiliar country. The appropriate treatment is often delayed, while patients are often dealt with in a manner that violates their human rights. Moreover, repatriation - which is vital in this case - is often delayed due to the lack of international protocols for the transportation and treatment of mentally ill travelers...

AIMS: Investments to promote public transport utilisation are being championed to achieve sustainable development, but the potential co-benefits for mental health are comparatively under-researched. We hypothesised that frequent users of public transport would be more likely to have better mental health (possibly due to increased levels of physical activity), but among the more frequent users, less favourable perceptions of public transport infrastructure (PPTI) could have a negative influence on mental health...

A hallmark feature of episodic memory is that of "mental time travel," whereby an individual feels they have returned to a prior moment in time. Cognitive and behavioral neuroscience methods have revealed a neurobiological counterpart: Successful retrieval often is associated with reactivation of a prior brain state. We review the emerging literature on memory reactivation and recapitulation, and we describe evidence for the effects of emotion on these processes. Based on this review, we propose a new model: Negative Emotional Valence Enhances Recapitulation (NEVER)...

PURPOSE: Veterans with dementia and their caregivers in remote areas may not have access to specialists to provide diagnosis, treatment, and education. The purpose of this clinical demonstration project was to examine the feasibility, acceptability, and impact of a video consultations clinic for veterans with dementia or memory complaints and their caregivers. METHODS: The dementia clinical video telehealth (CVT) consultation clinic was established to identify, diagnose, and treat dementia in veterans at sites distant from the main medical center...

This study explored specificity and visual perspective of mental time travel in schizophrenia. Fifteen patients with schizophrenia and 18 controls were recruited. Participants were asked to recall or imagine specific events according to cue words. Results showed that schizophrenia patients generated fewer specific events than controls, the recalled events were more specific than imagined events. Schizophrenia adopted less field perspective and more observer perspective than controls. These results suggested that patients with schizophrenia were impaired in mental time travel both in specificity and visual perspective...
