How Much of What We Learn in Virtual Reality Transfers to Real-World Navigation?

Past studies suggest that learning a spatial environment by navigating on a desktop computer can lead to significant acquisition of spatial knowledge, although typically less than navigating in the real world. Exactly how this might differ when learning in immersive virtual interfaces that offer a rich set of multisensory cues remains to be fully explored. In this study, participants learned a campus building environment by navigating (1) the real-world version, (2) an immersive version involving an omnidirectional treadmill and head-mounted display, or (3) a version navigated on a desktop computer with a mouse and a keyboard.

Precision, binding, and the hippocampus: Precisely what are we talking about?

Endel Tulving's proposal that episodic memory is distinct from other memory systems like semantic memory remains an extremely influential idea in cognitive neuroscience research. As originally suggested by Tulving, episodic memory involves three key components that differentiate it from all other memory systems: spatiotemporal binding, mental time travel, and autonoetic consciousness. Here, we focus on the idea of spatiotemporal binding in episodic memory and, in particular, how consideration of the precision of spatiotemporal context helps expand our understanding of episodic memory.

Intraindividual variability in sleep and perceived stress in young adults.

Objectives: Research suggests strong associations between habitual sleep parameters (eg, mean duration, timing, efficiency), perceived stress, and insomnia symptoms. The associations between intraindividual variability (IIV; night-to-night within-person variation) in sleep, perceived stress, and insomnia have not been explored. This study examined associations between IIV in subjectively and objectively determined sleep parameters and to perceived stress in young adults with and without insomnia.

Experience with morphosyntactic paradigms allows toddlers to tacitly anticipate overregularized verb forms months before they produce them.

When do children acquire abstract grammatical categories? Studies of 2- to 3-year-olds' productions of complete morphosyntactic paradigms (e.g., all legal determiners with all nouns) suggest relatively later category acquisition, while studies of infant discrimination of grammatical vs.

Concrete processing of action metaphors: Evidence from ERP.

The timing of sensory-motor activation during the comprehension of action verbs used in a metaphorical sense is not well understood. In the present Event Related Potential (ERP) study, participants read verbs in metaphoric (The church bent the rules), literal-concrete (The bodyguard bent the rod), and literal-abstract (The church altered the rules) conditions. The literal concreteness effect, obtained by subtracting the abstract from the concrete, was revealed as an N400, frontally distributed.

Introduction to the special series-behavioral medicine at 40: origins, achievements, and future directions.

The Journal of Behavioral Medicine emerged 40 years ago as a part of a concerted effort to promote a greater understanding of health and illness through the integrated lenses of behavioral and biomedical sciences. The aim of this special series is to commemorate the 40th anniversary of the Journal of Behavioral Medicine through state-of-the-science reviews synthesizing the origins, evolution, current status, and future directions of key aspects of the field. In this introduction, we outline the impetus for this special series and highlight the key themes across the included papers.

The Promoting Activity in Cancer Survivors (PACES) trial: a multiphase optimization of strategy approach to increasing physical activity in breast cancer survivors.

Background: Despite the significant, empirically supported benefits of physical activity, the majority of breast cancer survivors do not meet recommended guidelines for physical activity. A variety of effective strategies to increase physical activity in breast cancer survivors have been identified. However, it is unknown which of these strategies is most effective or how these strategies might be combined to optimize intervention effectiveness.

Bouldering psychotherapy reduces depressive symptoms even when general physical activity is controlled for: A randomized controlled trial.

Background: Bouldering psychotherapy (BPT) combines psychotherapeutic elements with physical activity (PA). It might be effective for reducing symptoms of depression, but so far, no study has assessed individuals' levels of PA to control for whether positive effects on depression can also be found when adjusting for participants' levels of PA. This is important because PA itself has been proven effective in reducing depression and therefore might be an important variable to account for - especially in therapies using sport as one therapeutic mechanism.

Exploring end-of-life interaction in dyads of parents and adult children: a protocol for a mixed-methods study.

Background: A considerable number of terminally-ill adult children are outlived by at least one parent and receive palliative care prior to their death. At the same time, adult children continue to be confronted with their parents' terminal illnesses and end-of-life situations. The current study explores the specifics of dyadic interaction at the end of life between a) adult children suffering from a life-threatening disease and their parents, and b) terminally ill parents and their adult children.

Positive parenting behaviors in women who spontaneously quit smoking during pregnancy: Clues to putative targets for preventive interventions.

Background: While the majority of pregnant smokers do not respond to intervention, little is known about how a subset of pregnant smokers known as spontaneous quitters achieve sustained biologically-confirmed abstinence through delivery in the absence of intervention. We explore a developmental framework to address this question by viewing spontaneous quitting as an adaptive parenting behavior, facilitated by abilities necessary for sensitive parenting, or responsiveness. Utilizing existing data, we examined responsiveness from parenting assessments in women who exhibited a variety of smoking patterns during pregnancy, including spontaneous quitting.

Rightward and leftward biases in temporal reproduction of objects represented in central and peripheral spaces.

The basis for how we represent temporal intervals in memory remains unclear. One proposal, the mental time line theory (MTL), posits that our representation of temporal duration depends on a horizontal mental time line, thus suggesting that the representation of time has an underlying spatial component. Recent work suggests that the MTL is a learned strategy, prompting new questions of when and why MTL is used to represent temporal duration, and whether time is always represented spatially.

A cognitive-behavioral and mindfulness-based group sleep intervention improves behavior problems in at-risk adolescents by improving perceived sleep quality.

Objective: The aim of this study was to test whether a cognitive-behavioral and mindfulness-based group sleep intervention would improve behavior problems in at-risk adolescents, and whether these improvements were specifically related to improvements in sleep.

Method: Secondary analysis of a randomized controlled trial conducted with 123 adolescent participants (female = 60%; mean age = 14.48, range 12.

Registry study to assess hair loss prevention with the Penguin Cold Cap in breast cancer patients receiving chemotherapy.

Purpose: Chemotherapy-induced alopecia is a distressing side effect of cancer treatment. The aim of this registry study was to assess efficacy and tolerability of scalp hypothermia using Penguin Cold Caps (Penguin) in breast cancer patients.

Methods: Hair loss was assessed by patients using a 100-point Visual Analog Scale (VAS) and by physicians using the 5-point Dean Scale at baseline, every 3-4 weeks during chemotherapy, and at least 1 month after completion of chemotherapy.

Visual integration enhances associative memory equally for young and older adults without reducing hippocampal encoding activation.

The ability to remember associations between previously unrelated pieces of information is often impaired in older adults (Naveh-Benjamin, 2000). Unitization, the process of creating a perceptually or semantically integrated representation that includes both items in an associative pair, attenuates age-related associative deficits (Bastin et al., 2013; Ahmad et al.

Does MAOA increase susceptibility to prenatal stress in young children?

Background: We previously demonstrated a gene-by-prenatal-environment interaction whereby the monoamine oxidase A gene (MAOA) modified the impact of prenatal tobacco exposure (PTE) on adolescent disruptive behavior (DB), with the MAOA risk genotype varying by sex. We extend this work by examining whether this mechanism is evident with another common adversity, prenatal stress exposure (PSE), and whether sex differences are present earlier in development in closer proximity to exposure.

Methods: Participants were 281 mothers and their 285 children derived from a prenatal cohort with in-depth prospective measures of PSE and PTE.

Person-Environment Mergence and Separation: Otto Rank's Psychology of Emotion, Personality, and Culture.

Between 1924 and 1939 Otto Rank put forward three major elements of a comprehensive theoretical edifice that has yet to be fully articulated. These are conceptually linked by the fundamental importance of person-environment mergence and separation. Rank's theory of emotions highlights anxiety as the affect of separation, and guilt as the feeling that binds the individual to others.

Cultural Humility and Hospital Safety Culture.

Hospital safety culture is an integral part of providing high quality care for patients, as well as promoting a safe and healthy environment for healthcare workers. In this article, we explore the extent to which cultural humility, which involves openness to cultural diverse individuals and groups, is related to hospital safety culture. A sample of 2011 hospital employees from four hospitals completed measures of organizational cultural humility and hospital safety culture.

Body mass and cognitive decline are indirectly associated via inflammation among aging adults.

Inflammatory models of neurodegeneration suggest that higher circulating levels of inflammation can lead to cognitive decline. Despite established independent associations between greater body mass, increased inflammation, and cognitive decline, no prior research has explored whether markers of systemic inflammation might mediate the association between body mass and changes in cognitive functioning. To test such a model, we used two longitudinal subsamples (ns=9066; 12,561) of aging adults from the English Longitudinal Study of Ageing (ELSA) study, which included two cognitive measures components of memory and executive functioning, as well as measurements of body mass and systemic inflammation, assessed via C-reactive protein (CRP).

Studying the teaching of kindness: A conceptual model for evaluating kindness education programs in schools.

Recent research suggests that school-based kindness education programs may benefit the learning and social-emotional development of youth and may improve school climate and school safety outcomes. However, how and to what extent kindness education programming influences positive outcomes in schools is poorly understood, and such programs are difficult to evaluate in the absence of a conceptual model for studying their effectiveness. In partnership with Kind Campus, a widely adopted school-based kindness education program that uses a bottom-up program framework, a methodology called concept mapping was used to develop a conceptual model for evaluating school-based kindness education programs from the input of 123 middle school students and approximately 150 educators, school professionals, and academic scholars.

Social Rhythm Therapies for Mood Disorders: an Update.

Social rhythms are patterns of habitual daily behaviors that may impact the timing of the circadian system directly or indirectly through light exposure. According to the social rhythm hypothesis of depression, depressed individuals possess a vulnerability in the circadian timing system that inhibits natural recovery after disrupting life events. Social rhythm therapies (SRTs) support the implementation of regular, daily patterns of activity in order to facilitate recovery of circadian biological processes and also to improve mood.

Sleep confers a benefit for retention of statistical language learning in 6.5month old infants.

Infants show robust ability to track transitional probabilities within language and can use this information to extract words from continuous speech. The degree to which infants remember these words across a delay is unknown. Given well-established benefits of sleep on long-term memory retention in adults, we examine whether sleep similarly facilitates memory in 6.

Interpreting suffering from illness: The role of culture and repressive suffering construal.

Rationale: Mental and physical illnesses are among the most prominent forms of suffering. Cultural worldviews provide tools for making sense of and coping with suffering. In this research, we examine how culture influences both experts' and laypeople's interpretation of suffering from illness.
