RESUMO

Autistic people frequently experience negative judgements from non-autistic people, often fuelled by misconceptions that autistic people lack empathy. Understanding responses to negative social judgement among autistic people is crucial because of the potential negative impact on wellbeing and future interactions. We investigated the role of autistic traits, social anxiety, and depression on behavioural indices of social rejection in 20 autistic (AUT; 11 males) and 40 non-autistic (N-AUT; 21 males) university students. Participants completed the Social Judgement Task (SJT) where they predicted whether they were liked by another person, then received feedback on whether those evaluations were correct. Participants also completed an Age Judgement Task (AJT) where they estimated the age of the pictured person. The AUT group had lower positive expectation scores, meaning less tendency to predict being liked. Across the whole sample, higher social anxiety predicted greater tendency to anticipate rejection from others, not autistic traits. These findings suggest early experiences of rejection might lead to a negative self-bias in autistic people and emphasise the importance of using a transdiagnostic approach by showing that social anxiety rather than autistic traits is associated with expectation of social rejection.

RESUMO

With the passage of the Health Information Technology for Economic and Clinical Health Act in 2009, Texas nurses were faced with the rapid uptake of technology driven by this legislation. Texas Nurses Association and Texas Organization for Nursing Leadership formed a partnership to collectively track the impact on practicing nurses. The Health IT Committee was commissioned to evaluate the changing health information technology environment and associated solutions. As such, a study in 2015, entitled "Statewide Study Assessing the Experiences of Nurses with their Electronic Health Records," was conducted. The follow-up study in 2020 was conducted to compare 2015 and 2020 findings to identify improvements made on nurses' satisfaction with EHRs and identify improvement opportunities. The study design was an exploratory descriptive comparative analysis with a cross-sectional survey from a random sample of Texas nurses for the two study periods of 2015 (n = 1177) and 2020 (n = 1117). The Clinical Information Systems Implementation Evaluation Scale and a demographic survey including the Meaningful Use Maturity-Sensitive Index were the measurement instruments. Results and key covariates are discussed along with recommendations for achieving more mature EHRs and more mature organizational culture and leadership.

RESUMO

Past research shows that individuals with Williams syndrome (WS) have heightened and prolonged eye contact. Using parent report measures, we examined not only the presence of eye contact but also its qualitative features. Study 1 included individuals with WS (n = 22, ages 6.0-36.3). Study 2 included children with different neurodevelopmental (ND) conditions (WS, autism spectrum condition, fragile X syndrome, attention-deficit/hyperactivity disorder) and children with neurotypical development (NT; n = 262, ages 4.0-17.11). Unusual eye contact features, including staring, were found in approximately half of the WS samples. However, other features such as brief glances were frequently found in WS and in all ND conditions, but not NT. Future research in ND conditions should focus on qualitative as well as quantitative features of eye contact.

RESUMO

Anxiety is the most significant mental health concern for both Williams syndrome (WS) and autism. Whilst WS and autism are characterized by some syndrome-specific social differences, less is known about cross-syndrome profiles of anxiety symptoms. Previous research has shown that Intolerance of Uncertainty (IU) is a core mechanism of anxiety maintenance for clinically anxious populations and for autistic children, adolescents, and adults. The only published study in this area for WS has shown some similar patterns-with an added emphasis on the role of sensory sensitivities-in a sample of older teens and adults (mean age = 24), with the authors highlighting the need for younger samples to consider developmental influences. Here we report a cross-syndrome, cross-sectional mediation analyses of children diagnosed with WS or autism, including data from parent surveys of 90 children with WS (n = 48) or autism (n = 42). Group differences showed higher trait levels on all measures for the autism group. Importantly, the relationship between social profile and anxiety was fully mediated by IU level for both groups. This suggests possible similar core mechanisms underlying anxiety in these conditions, and the possibility of generalized intervention approaches especially related to managing distress related to uncertainty in multiple contexts. LAY SUMMARY: Autism and Williams Syndrome share some similarities in social profile and also in anxiety traits, but there are also some key differences as well. Comparing them side-by-side at the same time improved identification of ways to reduce feelings of anxiety. We found that the intolerance of uncertainty affected the relationship between social profile and anxiety in the same way for young children diagnosed with autism or Williams syndrome, meaning that intervention approaches could be similar for both.

RESUMO

BACKGROUND: Academic outcomes for autistic individuals are heterogeneous, but the reasons for this are unknown. Attention is known to predict learning in typical development, but there is less evidence about this relationship in Autism Spectrum Disorders (ASD), even though attention is reported as atypical in this group. AIMS: To investigate reading and maths achievement profiles for children with and without an ASD, focusing on the role of attention in these profiles and to enable a better understanding of individual differences. METHODS: Reading, maths and attention abilities of 22 autistic children (6-16 years) and 59 TD children (6-11 years) were measured using standardised assessments. RESULTS: A hierarchical cluster analysis that included all children (N = 81) revealed three distinct transdiagnostic subgroups, characterised by children with good, average, and poorer divided attention and academic achievement respectively. Children with poorer attention and achievement displayed relative weaknesses in maths, while children with average or above-average attention and achievement showed no such weakness. CONCLUSIONS: The findings provide a novel insight into the relationship between attention and achievement and understanding individual differences in ASD and typical development.

RESUMO

Autism spectrum disorders (ASD) are associated with face perception atypicalities, and atypical experience with faces has been proposed as an underlying explanation. Studying the own-race advantage (ORA) for face recognition can reveal the effect of experience on face perception in ASD, although the small number of studies in the area present mixed findings. This study probed the ORA in ASD by comparing two cultural groups simultaneously for the first time. Children with ASD in the UK (N = 16) and Japan (N = 26) were compared with age- and ability-matched typically developing (TD) children in the UK (N = 16) and Japan (N = 26). Participants completed a two-alternative forced-choice task, whereby they had to recognize a just seen face from a foil which was manipulated in one of four ways (IC: identity change; EE: easy eyes; HE: hard eyes; HM: hard mouth). Face stimuli were Asian and Caucasian, and thus the same stimuli were own and other race depending on the cultural group. The ASD groups in the UK and Japan did not show impaired face recognition abilities, or impairments with recognizing faces depending on manipulations to the eye region, and importantly they showed an ORA. There was considerable heterogeneity in the presence of the ORA in ASD and TD and also across cultures. Children in Japan had higher accuracy than children in the UK, and TD children in Japan did not show an ORA. This cross-cultural study challenges the view that atypical experiences with faces lead to a reduced/absent ORA in ASD.

RESUMO

The number of university students with autism is increasing, and it is crucial that these students can access adequate support. An online questionnaire was completed by 26 autistic students and 158 non-autistic students enrolled at UK universities to investigate social and academic experiences. Autistic students self-reported significant challenges and more mental health difficulties than non-autistic students. Significant challenges focused on the social components of university life, including social skills, social support opportunities, and levels of ASD awareness from others. Many strengths were also reported regarding academic skills of autistic university students. Importantly, there were more thoughts of withdrawal by the students with autism highlighting the need for support. These data can inform university student support services.

RESUMO

BACKGROUND: Research has demonstrated evidence for increased perceptual capacity in autism: autistic people can process more information at any given time than neurotypical individuals. The implications of this for educating autistic pupils have not been investigated. For example, this ability to process more information at any given time may explain why autistic children sometimes process more peripheral task-irrelevant information than neurotypical individuals (e.g. in background classroom wall-displays). AIMS: The current study assessed the impact of different types of background information on autistic and non-autistic children's ability to perform a learning task. METHODS AND PROCEDURES: Autistic (N = 23) and non-autistic (N = 50) children took part in a computer-based task designed to simulate a lesson. They watched three videos of a teacher telling a story, each with a different background condition: blank, relevant images, or irrelevant images. OUTCOMES AND RESULTS: When the visual display contained story-relevant information, both groups recalled background information in addition to the central story. When the background displays were irrelevant to the story, autistic children recalled more background information than their neurotypical peers, yet maintained their ability to recall information from the central story. CONCLUSION AND IMPLICATIONS: The current study suggests that pupils' perceptual capacity- including those on the autistic spectrum - can indeed be capitalised on to support learning in the classroom. To do so, however, we must ensure that the child can use their capacity for task-relevant processing, rather than irrelevant distractions.

RESUMO

Anxiety is a prevalent mental health issue for individuals with Williams syndrome (WS). Relatively little is known about the developmental course of anxiety, or how it links with core features of WS, namely social and executive functioning (EF). In this study, parent-reports of anxiety were compared across a 4-year period (N = 17), and links between anxiety, social and EF were explored from concurrent parent-reports (N = 26). Results indicated that high anxiety persisted over time, and anxiety was related to impairments in both social and executive functioning. Importantly, results indicated that impairments in EFs may drive the links between anxiety and social functioning. This timely investigation provides new insights into anxiety in WS and highlights potential areas for intervention.

RESUMO

For nearly 50 years, Therapeutic Touch (TT) has contributed to advancing holistic nursing practice and has been recognized as a uniquely human approach to healing. This narrative explores the development of a practice-based theory of healing through TT, which occurred between 2010 and 2016. Through the in-depth self-inquiry of participatory reflective dialogue in concert with constant narrative analysis, TT practitioners revealed the meaning of healing within the context of their TT practice. As the community of TT experts participated in an iterative process of small group and community dialogues with analysis and synthesis of emerging themes, the assumptions and concepts central to a theory of healing emerged, were clarified and verified. Exemplars of practice illustrate the concepts. A model of the theory of healing illuminates the movement and relationship among concepts and evolved over time. Feedback from nursing and inter-professional practitioners indicate that the theory of healing, while situated within the context of TT, may be useful in advancing holistic nursing practice, informing healing and caring approaches, stimulating research and education, and contributing to future transformations in health care.

RESUMO

Paying attention is a critical first step toward learning. For children in primary school classrooms there can be many things to attend to other than the focus of a lesson, such as visual displays on classroom walls. The aim of this study was to use eye-tracking techniques to explore the impact of visual displays on attention and learning for children. Critically, we explored these issues for children developing typically and for children with autism spectrum disorder (ASD). Both groups of children watched videos of a teacher delivering classroom activities-2 of "story-time" and 2 mini lessons. Half of the videos each child saw contained high levels of classroom visual displays in the background (high visual display [HVD]) and half had none (no visual display [NVD]). Children completed worksheets after the mini lessons to measure learning. During viewing of all videos children's eye movements were recorded. The presence of visual displays had a significant impact on attention for all children, but to a greater extent for children with ASD. Visual displays also had an impact on learning from the mini lessons, whereby children had poorer learning scores in the HVD compared with the NVD lesson. Individual differences in age, verbal, nonverbal, and attention abilities were important predictors of learning, but time spent attending the visual displays in HVD was the most important predictor. This novel and timely investigation has implications for the use of classroom visual displays for all children, but particularly for children with ASD. (PsycINFO Database Record

RESUMO

Nursing professionals are at the frontline of the health information technology revolution. The Texas Nurses Association and Texas Organization of Nurse Executives partnered to evaluate the changing health technology environment in Texas, in particular the nurses' satisfaction with the use of clinical information systems. A descriptive exploratory study using the Clinical Information System Implementation Evaluation Scale and a newly developed Demographic Survey and the Meaningful Use Maturity-Sensitive Index, with a narrative component, was conducted in 2014 and 2015. Nurses across Texas received an electronic invitation to participate in the survey, resulting in 1177 respondents. Exploratory factor analysis revealed that variables of the Meaningful Use Maturity-Sensitive Index and Clinical Information System Implementation Evaluation Scale show strong interrater reliability, with Cronbach's α scores of .889 and .881, respectively, and thereby inform the survey analysis, indicating and explaining variations in regional and institutional trends with respect to satisfaction. For example, the maturity of a clinical information system within an organization and age of the nurse significantly influence the probability of nurse satisfaction (P < .05). Qualitative analysis of nurses' narratives further explained the nurses' experiences. Recommendations for future research and educational were identified.

RESUMO

Interpersonal distance regulation is crucial for successful social interactions. We investigated personal space awareness in Williams syndrome (WS) and autism spectrum disorder (ASD) compared to typical development. Parents reported that individuals with WS and ASD were significantly more likely than those developing typically to invade the personal space of others. WS individuals were reported to have the least awareness of the personal space boundaries of others. Despite the suggested opposing social profiles of WS and ASD, some similarities are present in the ability, or indeed inability, to regulate interpersonal distance during social interactions. Findings are discussed in relation to implications of atypical amygdala function, inhibitory control and anxiety on real-world behaviour for such socially vulnerable groups.

RESUMO

Individuals with autism spectrum disorder do not just 'grow out of' their early difficulties in understanding the social world. Even for those who are cognitively able, autism-related difficulties continue into adulthood. Atypicalities attending to and interpreting communicative signals from others can provide barriers to success in education, employment and relationships. In the current study, we use eye-tracking during real social interaction to explore attention to social cues (e.g. face, eyes, mouth) and links to social awareness in a group of cognitively able University students with autism spectrum disorder and typically developing students from the same University. During the interaction, students with autism spectrum disorder showed less eye fixation and more mouth fixation than typically developing students. Importantly, while 63% of typically developing participants reported thinking they were deceived about the true nature of the interaction, only 9% of autism spectrum disorder participants picked up this subtle social signal. We argue that understanding how these social attentional and social awareness difficulties manifest during adulthood is important given the growing number of adults with autism spectrum disorder who are attending higher level education. These adults may be particularly susceptible to drop-out due to demands of coping in situations where social awareness is so important.

RESUMO

Recent research suggests that children with autism spectrum disorder (ASD) experience some level of motor difficulty, and that this may be associated with social communication skills. However, other studies show that children with language impairments, but without the social communication problems, are at risk of motor difficulties as well. The aim of the present study was to determine if children with ASD have syndrome-specific motor deficits in comparison to children with specific language impairment (SLI). We used an independent groups design with three groups of children (8-10 years old) matched on age and nonverbal IQ: an ASD group, an SLI group, and a typically developing (TD) group. All of the children completed an individually administered, standardized motor assessment battery. We found that the TD group demonstrated significantly better motor skills than either the ASD or SLI groups. Detailed analyses of the motor subtests revealed that the ASD and SLI groups had very similar motor profiles across a range of fine and gross motor skills, with one exception. We conclude that children with ASD, and SLI, are at risk of clinically significant motor deficits. However, future behavioral and neurological studies of motor skills in children with ASD should include an SLI comparison group in order to identify possible autism-specific deficits.

RESUMO

The application of fluorescently-labeled antibodies for flow cytometric identification and characterization of specific cell types within heterogeneous populations by their protein expression profile is well established. While detection of proteins is informative, concomitant transcript analysis in the same cells would provide a more complete and comprehensive view of intracellular signaling events. We recently reported on the efficient detection of RNA in suspension cells for flow cytometric analysis. The improved RNA flow cytometry procedure described here allows for the specific labeling of multiple RNA species, and is compatible with antibody-based targeting of extracellular and intracellular antigens for multiplexing purposes. To show proof of concept, human peripheral blood mononuclear cells were stimulated with phorbol 12-myristate 13-acetate and ionomycin for a maximum of 5 h, during which their CD4 and interferon-gamma (IFN-γ) transcript and protein levels were monitored. Substantial and increasing numbers of IFN-γ mRNA+ cells were detected within 30 min after initiation of induction, while IFN-γ protein+ cells could only be discerned at 1 h and beyond. Surprisingly, resting lymphocytes contained less CD4 mRNA but more of the protein per cell compared with monocytes, revealing a difference in the relationship of transcript and protein levels in these two cell types. We additionally applied monensin, which is commonly used to block cytokine secretion, and found that IFN-γ mRNA can still be analyzed consistently using the improved RNA flow cytometry staining method. Notably, a subset of IFN-γ mRNA(-)/protein+ cells that were not observed in the absence of monensin became apparent at the 5-h mark. This subset probably represents cells that have accumulated IFN-γ protein, but no longer transcribe mRNA. Collectively, the results described here exemplify how the improved RNA flow cytometry labeling procedure can be applied to simultaneously assess mRNA and protein dynamics to gain insight into the regulation of gene transcription and translation in individual cells.

RESUMO

The developmental disorder Williams syndrome (WS) has been associated with an atypical social profile of hyper-sociability and heightened social sensitivity across the developmental spectrum. In addition, previous research suggests that both children and adults with WS have a predisposition towards anxiety. The current research aimed to explore the profiles of social behaviour and anxiety across a broad age range of individuals with the disorder (n = 59, ages 6-36 years). We used insights from parental reports on two frequently used measures, the Spence Children's Anxiety Scale (SCAS-P) and the Social Responsiveness Scale (SRS). Severity of anxiety was correlated with a greater degree of social dysfunction as measured by the SRS in this group. We split the group according to high or low anxiety as measured by the SCAS-P and explored the profile of social skills for the two groups. Individuals high and low in anxiety differed in their social abilities. The results emphasise the need to address anxiety issues in this disorder and to consider how components of anxiety might relate to other features of the disorder.

RESUMO

Individuals with the neuro-developmental disorder Williams syndrome (WS) are characterised by a combination of features which makes this group vulnerable socially, including mild-moderate cognitive difficulties, pro-social drive, and indiscriminate trust. The purpose of this study was to explore a key socio-communicative skill in individuals with WS, namely, mental state recognition abilities. We explored this skill in a detailed way by looking at how well individuals with WS recognise complex everyday mental states, and how they allocate their attention while making these judgements. Participants with WS were matched to two typically developing groups for comparison purposes, a verbal ability matched group and a chronological age matched group. While eye movements were recorded, participants were shown displays of eight different mental states in static and dynamic form, and they performed a forced-choice judgement on the mental state. Mental states were easier to recognise in dynamic form rather than static form. Mental state recognition ability for individuals with WS was poorer than expected by their chronological age, and at the level expected by their verbal ability. However, the pattern of mental state recognition for participants with WS varied according to mental state, and we found some interesting links between ease/difficulty recognising some mental states (worried/do not trust) and the classic behavioural profile associated with WS (high anxiety/indiscriminate trust). Furthermore, eye tracking data revealed that participants with WS allocated their attention atypically, with less time spent attending the information from the face regions. This challenges the widely held understanding of WS being associated with prolonged face and eye gaze, and indicates that there is more heterogeneity within this disorder in terms of socio-perception than previous reports would suggest.

RESUMO

BACKGROUND: From a young age the typical development of social functioning relies upon the allocation of attention to socially relevant information, which in turn allows experience at processing such information and thus enhances social cognition. As such, research has attempted to identify the developmental processes that are derailed in some neuro-developmental disorders that impact upon social functioning. Williams syndrome (WS) and autism are disorders of development that are characterized by atypical yet divergent social phenotypes and atypicalities of attention to people. METHODS: We used eye tracking to explore how individuals with WS and autism attended to, and subsequently interpreted, an actor's eye gaze cue within a social scene. Images were presented for 3 seconds, initially with an instruction simply to look at the picture. The images were then shown again, with the participant asked to identify the object being looked at. Allocation of eye gaze in each condition was analyzed by analysis of variance and accuracy of identification was compared with t tests. RESULTS: Participants with WS allocated more gaze time to face and eyes than their matched controls, both with and without being asked to identify the item being looked at; while participants with autism spent less time on face and eyes in both conditions. When cued to follow gaze, participants with WS increased gaze to the correct targets; those with autism looked more at the face and eyes but did not increase gaze to the correct targets, while continuing to look much more than their controls at implausible targets. Both groups identified fewer objects than their controls. CONCLUSIONS: The atypicalities found are likely to be entwined with the deficits shown in interpreting social cognitive cues from the images. WS and autism are characterized by atypicalities of social attention that impact upon socio-cognitive expertise, but, importantly, the type of atypicality is syndrome specific.
