Interpretability and clinical utility of the strength and stressors in parenting questionnaire.

This study aimed to enhance the interpretability and clinical utility of the strength and stressors in parenting (SSF) questionnaire, a parent-reported questionnaire designed to assess strength, stress and associated risks of mental ill-health in parents of children with developmental disabilities. Responses to the SSF and a demographic questionnaire were collected from 576 parents of children with (n = 203) and without (n = 373) developmental disabilities. To enhance the interpretability of the SSF, a subset of 129 parents were invited to complete an additional questionnaire consisting of three free-text questions regarding recent help-seeking behavior, experiences of mental ill-health and experiences of parenthood.

Effect of vertical, horizontal, and combined plyometric training on jump, sprint and change of direction performance in male soccer players.

Purpose: The purpose of this study was to compare the effects of vertical (VPT), horizontal (HPT) and combined vertical and horizontal (V+HPT) plyometric training on sprint, jump and change of direction (COD) performance in adult male soccer players.

Method: Participants were randomly allocated into VPT (n = 8), HPT (n = 8) and V+HPT (n = 8) groups which undertook eight weeks of PT, executing 100 foot contacts per session, twice weekly.

Results: Though demonstrably effective, no specific one of the three applied programmes enhanced performance to a greater extent than another with only the 40 m sprint for the HPT group (mean difference = 0.

FreDESS: a clinical tool for perceptual evaluation of stuttering.

Aim: Stuttering is a communication disorder that involves both manifest speech disfluencies and associated symptoms. The purpose of the present study was to introduce an easily administered and ecologically valid assessment tool designed for perceptual evaluation of stuttered speech, FreDESS (frequency of stuttering events, duration of events, effort, secondary behaviours, and severity). More specifically, we wanted to study its reliability and validity.

Gender-Affirming Voice Training for Trans Women: Acoustic Outcomes and Their Associations With Listener Perceptions Related to Gender.

Objectives: To investigate acoustic outcomes of gender-affirming voice training for trans women wanting to develop a female sounding voice and to describe what happens acoustically when male sounding voices become more female sounding.

Study Design: Prospective treatment study with repeated measures.

Methods: N = 74 trans women completed a voice training program of 8-12 sessions and had their voices audio recorded twice before and twice after training.

Gender-Affirming Voice Training for Trans Women: Effectiveness of Training on Patient-Reported Outcomes and Listener Perceptions of Voice.

Purpose: Although speech-language pathologists have provided gender-affirming voice training for trans women since the 1970s, evidence for this training's effectiveness remains weak. Our study aimed to redress limitations of earlier studies and evaluate voice training effects on outcomes important to trans women.

Method: Seventy-four trans women (19-54 years old) who wanted a more female-sounding voice were recruited through two health facilities and provided with an eight- to 12-session voice training program based on contemporary literature, usual clinical practice, and client-centered care principles.

A Cross-Sectional Investigation of the Impact of Stuttering on Swedish Females and Males in Childhood, Adolescence, and Young Adulthood.

Purpose: We aimed to cross-sectionally describe the impact of stuttering on persons who stutter (PWS): children, adolescents, and young adults. Based on previous research on PWS and psychosocial health in the general population, we hypothesized that (a) the adverse impact of stuttering in PWS would be larger among adolescents than children and young adults and that (b) females, especially adolescent females, would report being more adversely impacted by their stuttering than males.

Method: We pooled samples of Swedish PWS, obtaining 162 individuals (75 females and 87 males), aged 7-30 years.

Infection and speech: Disfluency and other speech symptoms in Pediatric Acute-onset Neuropsychiatric Syndrome.

Introduction: In the early 20 century a link between infection and speech disfluency was discussed. Recent reports indicate that PANS (Pediatric Acute-onset Neuropsychiatric Syndrome), and PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections) may be associated with a high incidence of speech disfluency. The present study specifically investigates disfluency and other speech symptoms following onset of PANS and PANDAS.

Asking parents about babbling at 10 months produced valid answers but did not predict language screening result 2 years later.

Aim: We evaluated the concurrent and predictive validity of questions to parents of 10-month-old children about babbling.

Methods: Children with at least one native Swedish-speaking parent were eligible for inclusion in this prospective longitudinal study. The parents were asked three questions about babbling at a routine healthcare visit.

Children and adolescents with speech sound disorders are more likely to have orofacial dysfunction and malocclusion.

Background: Children with speech sound disorders (SSD) form a heterogeneous group that differs in terms of underlying cause and severity of speech difficulties. Orofacial dysfunction and malocclusions have been reported in children with SSD. However, the association is not fully explored.

On the Benefits of Speech-Language Therapy for Individuals Born With Cleft Palate: A Systematic Review and Meta-Analysis of Individual Participant Data.

Purpose: Cleft lip and/or palate (CLP) is a common birth defect, and after reconstructive surgery, about 50% of children at 5 years of age have speech deviations and are referred to speech-language therapy (SLT). The peer-reviewed evidence for the benefit of SLT has been uncertain. Our objective was to systematically review and meta-analytically summarize the benefit of SLT for individuals born with CLP.

A preliminary validation of a dynamic speech motor assessment for Swedish-speaking children with childhood apraxia of speech.

Objective: Children with speech sound disorders (SSDs) have difficulties affecting different levels of speech production. For treatment to be beneficial, it is important to differentiate between Childhood Apraxia of Speech (CAS) - a motor speech disorder with deficits in speech praxis - and other SSDs (nonCAS-SSD). We have previously developed a motor speech examination Dynamisk motorisk talbedömning (DYMTA).

Larger reported impact of stuttering in teenage females, compared to males - A comparison of teenagers' result on Overall Assessment of the Speaker's Experience of Stuttering (OASES).

Purpose: The aim of this cross-sectional study was to explore the impact and experience of stuttering, and attitude to communication for female and male teenagers who stutter (TWS) in comparison with teenagers with no stutter (TWNS).

Methods: The Swedish version of the Overall Assessment of the Speaker's Experience of Stuttering (OASES-T-S), was administered to 56 TWS, 13-17 years old (26 females, 30 males). An adapted version of OASES, Attitude to Speech and Communication (ASC), was administered to 233 TWNS.

A gentle reminder that mean does not imply modal behavior: Few are in-group biased in minimal groups.

Previous research reports that people organized into newly formed, arbitrary groups (i.e., minimal groups) are on average in-group biased.

Organosolv lignin hydrophobic micro- and nanoparticles as a low-carbon footprint biodegradable flotation collector in mineral flotation.

Flotation is a key step during mineral separation. Xanthates are the most commonly used collectors for recovering Cu, Ni, and Zn from sulphide ores. However, xanthates are fossil-based and toxic for the environment.

When Perception Trumps Reality.

Is semantic priming driven by the objective or perceived meaning of the priming stimulus? This question is relevant given that many studies suggest that the objective meaning of invisible stimuli can influence cognitive processes and behavior. In an experiment involving 66 participants, we tested how the perceived meaning of misperceived stimuli influenced response times. Stroop priming (i.

Subliminal or not? Comparing null-hypothesis and Bayesian methods for testing subliminal priming.

A difficulty for reports of subliminal priming is demonstrating that participants who actually perceived the prime are not driving the priming effects. There are two conventional methods for testing this. One is to test whether a direct measure of stimulus perception is not significantly above chance on a group level.

Reversed Priming Effects May Be Driven by Misperception Rather than Subliminal Processing.

A new paradigm for investigating whether a cognitive process is independent of perception was recently suggested. In the paradigm, primes are shown at an intermediate signal strength that leads to trial-to-trial and inter-individual variability in prime perception. Here, I used this paradigm and an objective measure of perception to assess the influence of prime identification responses on Stroop priming.

Asymmetric transfer of sound localization learning between indistinguishable interaural cues.

Learning in perceptual tasks is typically highly specific to the trained stimulus parameters. However, can learning be specific to a stimulus parameter that is perceptually indistinguishable from another? We assessed this question using a perceived sound location task in which the perceived sound location was created through either an interaural time difference (ITD) cue or an interaural level difference (ILD) cue. We used the same transient, broadband sound (clicks) for both cues, and after training on one of the cues, listeners switched cue mid-session.

High negative valence does not protect emotional event-related potentials from spatial inattention and perceptual load.

Previous research suggests that intense, emotional pictures at fixation elicit an early posterior negativity (EPN) and a late positive potential (LPP) despite manipulations of spatial inattention and perceptual load. However, if high emotional intensity protects against such manipulations, then these manipulations should reduce emotional effects on EPN and LPP more strongly for medium than for intense emotional pictures. To test this prediction, pictures that were high negative, medium negative, or neutral were shown at fixation, and a small letter string was superimposed on the picture center.

Processing of unattended, simple negative pictures resists perceptual load.

As researchers debate whether emotional pictures can be processed irrespective of spatial attention and perceptual load, negative and neutral pictures of simple figure-ground composition were shown at fixation and were surrounded by one, two, or three letters. When participants performed a picture discrimination task, there was evidence for motivated attention; that is, an early posterior negativity (EPN) and late positive potential (LPP) to negative versus neutral pictures. When participants performed a letter discrimination task, the EPN was unaffected whereas the LPP was reduced.

Emotional event-related potentials are reduced if negative pictures presented at fixation are unattended.

Viewing of emotional pictures elicits two event-related potentials (ERPs) to emotional versus neutral pictures: an early posterior negativity (EPN) and a late positive potential (LPP). Because it is unresolved whether these indexes of emotional processing are reduced to task-irrelevant pictures at fixation, negative and neutral pictures from the International Affective Picture Set (IAPS) were shown at fixation together with 6 letters that surrounded the pictures. In separate tasks, participants were instructed to attend either the pictures or the letters.

Nonemotional features suppress early and enhance late emotional electrocortical responses to negative pictures.

Neural processing of emotional pictures is often indexed by two electrocortical responses: the early posterior negativity (EPN) and the late positive potential (LPP). Because emotional pictures vary in nonemotional features (e.g.

Influence of colloidal interactions on pigment coating layer structure formation.

The consolidation of pigment coating layers was simulated using a three-dimensional particle dynamics model. The model included hydrodynamic interactions as well as colloidal force models and the Brownian motion. The impact of various colloidal model parameters on the z-direction solids profile development and coating layer thickness was investigated.
