Gamma and theta/alpha-band oscillations in the electroencephalogram distinguish the content of inner speech.

Inner speech refers to the silent production of language in one's mind. As a purely mental action without obvious physical manifestations, inner speech has been notoriously difficult to quantify. Inner speech is thought to be closely related to overt speech.

Integrating Videoconferencing Therapist Guidance Into Stepped Care Internet-Delivered Cognitive Behavioral Therapy for Child and Adolescent Anxiety: Noninferiority Randomized Controlled Trial.

Background: Self-guided internet-delivered cognitive behavioral therapy (ICBT) achieves greater reach than ICBT delivered with therapist guidance, but demonstrates poorer engagement and fewer clinical benefits. Alternative models of care are required that promote engagement and are effective, accessible, and scalable.

Objective: This randomized trial evaluated whether a stepped care approach to ICBT using therapist guidance via videoconferencing for the step-up component (ICBT-SC[VC]) is noninferior to ICBT with full therapist delivery by videoconferencing (ICBT-TG[VC]) for child and adolescent anxiety.

Psychological symptoms, quality of life and dyadic relations in family members of intensive care survivors: a multicentre, prospective longitudinal cohort study.

Background: There is scarce literature evaluating long term psychological or Quality of Life (QoL) outcomes in family members of ICU survivors, who have not experienced invasive ventilation. The objective was to compare long-term psychological symptoms and QoL outcomes in family members of intubated versus non-intubated ICU survivors and to evaluate dyadic relationships between paired family members and survivors.

Methods: Prospective, multicentre cohort study among four medical-surgical ICUs in Australia.

No electrophysiological evidence for semantic processing during inattentional blindness.

A long-standing question concerns whether sensory input can reach semantic stages of processing in the absence of attention and awareness. Here, we examine whether the N400, an event related potential associated with semantic processing, can occur under conditions of inattentional blindness. By employing a novel three-phase inattentional blindness paradigm designed to maximise the opportunity for detecting an N400, we found no evidence for it when participants were inattentionally blind to the eliciting stimuli (related and unrelated word pairs).

Two universal school-based prevention programs for depression and anxiety: 24-Month follow-up of an RCT.

Background And Objectives: Transdiagnostic approaches have been promoted as a means of maximising preventative effects across multiple problems with depression and anxiety suitable targets as they appear to have highly interconnected systems in pathology development and maintenance. This study investigated long-term effects of two universal school-based programs, Emotion Regulation (ER) and Behavioral Activation (BA), that sought to prevent depression and anxiety by targeting worry (a transdiagnostic feature) to promote resilience.

Methods: This follow-up study captured data from 162 of 316 initial students (aged 8-13; 52.

Continuous psychophysics for two-variable experiments; A new "Bayesian participant" approach.

Interest in continuous psychophysical approaches as a means of collecting data quickly under natural conditions is growing. Such approaches require stimuli to be changed randomly on a continuous basis so that participants can not guess future stimulus states. Participants are generally tasked with responding continuously using a continuum of response options.

Target motion misjudgments reflect a misperception of the background; revealed using continuous psychophysics.

Determining the velocities of target objects as we navigate complex environments is made more difficult by the fact that our own motion adds systematic motion signals to the visual scene. The flow-parsing hypothesis asserts that the background motion is subtracted from visual scenes in such cases as a way for the visual system to determine target motions relative to the scene. Here, we address the question of why backgrounds are only subtracted in lab settings.

A controlled evaluation of social prescribing on loneliness for adults in Queensland: 8-week outcomes.

Introduction: There have been few controlled evaluations of Social Prescribing (SP), in which link workers support lonely individuals to engage with community-based social activities. This study reports early outcomes of a trial comparing General Practitioner treatment-as-usual (TAU) with TAU combined with Social Prescribing (SP) in adults experiencing loneliness in Queensland.

Methods: Participants were 114 individuals who were non-randomly assigned to one of two conditions (SP,  = 63; TAU,  = 51) and assessed at baseline and 8 weeks, on primary outcomes (loneliness, well-being, health service use in past 2 months) and secondary outcomes (social anxiety, psychological distress, social trust).

Positive school climate and strong school identification as protective factors of adolescent mental health and learning engagement: A longitudinal investigation before and during COVID-19.

The COVID-19 pandemic resulted in significant disruptions for children and youth around the world, especially given school closures and shifts in teaching modes (on-line and hybrid). However, the impact of these disruptions remains unclear given data limitations such as a reliance on cross-sectional and/or short-interval surveys as well as a lack of broad indicators of key outcomes of interest. The current research employs a quasi-experimental design by using an Australian four-year longitudinal survey with student responses from Grade 7 to 10 (aged 12-15 years old) (N = 8,735 from 20 schools) in one education jurisdiction.

What next for behaviour change professional development in general practice? Insights from an environmental scan and workshops.

Background: A key role of general practice professionals (that is, GPs, and general practice nurses [GPNs]) is to support patients to change behaviours. Traditional approaches to assisting patients with, and learning about, behaviour change have modest outcomes.

Aim: To explore behaviour change with GPs and GPNs and the availability of related professional development (PD) opportunities.

COVID-19 infection associated with poorer mental health in a representative population sample.

Objective: There is limited evidence of the direct effects of COVID-19 infection on mental health, and whether these are influenced by vaccination or physical health symptoms. We aimed to investigate the relationships of COVID-19 infection, current symptom presentation, and vaccination status with mental health symptoms in adults.

Study Design And Setting: A cross-sectional sample of the Australian adult population that was representative by age, gender, and location was recruited through market research panels (N = 1407, 51.

Core features of callous-unemotional traits: a cross-cultural comparison of youth in four countries.

With considerable debate concerning the impact of culture on the expression of callous-unemotional (CU) traits, it is unclear whether the core features of CU traits generalize to youth across cultures. This study aimed to examine whether cultural differences are reflected in the core features of CU traits and the associations among these features. Network analysis was employed to identify the core features and to examine the network structure of CU traits operationalized by the Inventory of Callous Unemotional traits (ICU) in four community youth samples from different nations (Australia, N = 190; the UK, N = 437; the USA, N = 330; China, N = 503).

Neurophysiological evidence of motor preparation in inner speech and the effect of content predictability.

Self-generated overt actions are preceded by a slow negativity as measured by electroencephalogram, which has been associated with motor preparation. Recent studies have shown that this neural activity is modulated by the predictability of action outcomes. It is unclear whether inner speech is also preceded by a motor-related negativity and influenced by the same factor.

Callous-unemotional Traits and Child Response to Teacher Rewards, Discipline, and Instructional Methods in Chinese Preschools: A Classroom Observation Study.

Atypical responses to teacher rewards, discipline and different forms of instructional methods have been identified as potential contributors to disruptive behavior, low school engagement, and academic underachievement in children with elevated callous-unemotional (CU) traits. To date, research on CU traits in schools has relied on interview or questionnaire methods and has predominantly been conducted in Western countries. Thus, the present study aims to investigate the relationships between CU traits and children's responses to teacher rewards, discipline and instructional methods in the Chinese preschool context using classroom observation.

Street soccer and homelessness: Exploring social identities, health, and well-being.

Membership in social and physical activity groups has the potential to help people with a range of physical and mental health challenges. The purpose of this study was to examine the experiences of members of a unique physical activity group: people who were formerly or currently homeless participating in a street soccer program in Western Canada. Ten participants in the Vancouver Street Soccer League (VSSL) were interviewed about the extent to which this program fostered a sense of community, social connectivity, and quality of life among people with experience of homelessness.

Daily Cannabidiol Administration for 10 Weeks Modulates Hippocampal and Amygdalar Resting-State Functional Connectivity in Cannabis Users: A Functional Magnetic Resonance Imaging Open-Label Clinical Trial.

Cannabis use is associated with brain functional changes in regions implicated in prominent neuroscientific theories of addiction. Emerging evidence suggests that cannabidiol (CBD) is neuroprotective and may reverse structural brain changes associated with prolonged heavy cannabis use. In this study, we examine how an ∼10-week exposure of CBD in cannabis users affected resting-state functional connectivity in brain regions functionally altered by cannabis use.

Examining the relationship between aerobic fitness and cognitive control processes: An SFT and ERP study.

Previous studies have demonstrated a positive relationship between aerobic fitness and cognitive control, the ability to inhibit distractions (conflict control) or impulsive actions (response inhibition). However, it is unknown whether these sub-processes and their underlying information processing capacity are differentially related to aerobic fitness. To address this question, we employed a go/no-go version of the redundant-target task, which was administered concurrently with the recording of event-related potentials (ERPs) and the use of a reaction-time based diagnostic tool known as system factorial technology (SFT).

An updating-based working memory load alters the dynamics of eye movements but not their spatial extent during free viewing of natural scenes.

The relationship between spatial deployments of attention and working memory load is an important topic of study, with clear implications for real-world tasks such as driving. Previous research has generally shown that attentional breadth broadens under higher load, while exploratory eye-movement behaviour also appears to change with increasing load. However, relatively little research has compared the effects of working memory load on different kinds of spatial deployment, especially in conditions that require updating of the contents of working memory rather than simple retrieval.

The receiver operating characteristic area under the curve (or mean ridit) as an effect size.

Several authors have recommended adopting the receiver operator characteristic (ROC) area under the curve (AUC) or mean ridit as an effect size, arguing that it measures an important and interpretable type of effect that conventional effect-size measures do not. It is base-rate insensitive, robust to outliers, and invariant under order-preserving transformations. However, applications have been limited to group comparisons, and usually just two groups, in line with the popular interpretation of the AUC as measuring the probability that a randomly chosen case from one group will score higher on the dependent variable than a randomly chosen case from another group.

Eating disorders in weight-related therapy (EDIT): Protocol for a systematic review with individual participant data meta-analysis of eating disorder risk in behavioural weight management.

The Eating Disorders In weight-related Therapy (EDIT) Collaboration brings together data from randomised controlled trials of behavioural weight management interventions to identify individual participant risk factors and intervention strategies that contribute to eating disorder risk. We present a protocol for a systematic review and individual participant data (IPD) meta-analysis which aims to identify participants at risk of developing eating disorders, or related symptoms, during or after weight management interventions conducted in adolescents or adults with overweight or obesity. We systematically searched four databases up to March 2022 and clinical trials registries to May 2022 to identify randomised controlled trials of weight management interventions conducted in adolescents or adults with overweight or obesity that measured eating disorder risk at pre- and post-intervention or follow-up.

Estimating statistical power for ERP studies using the auditory N1, Tb, and P2 components.

The N1, Tb, and P2 components of the event-related potential (ERP) are thought to reflect the sequential processing of auditory stimuli in the human brain. Despite their extensive use in biological, cognitive, and clinical neuroscience, there are no guidelines for how to appropriately power ERP studies using these components. In the present study, we investigated how the number of trials, number of participants, effect magnitude, and study design influenced statistical power.
