Theories Of Emotions

AbstractAutism spectrum disorder (ASD) includes a variety of childhood-onset and lifelong neurodevelopmental condition with an enduring impact on multiple domains of functioning characterized by persistent deficits in social communication, restricted and repetitive behavior interest, and activities. They often find it hard to recognize and control emotions but their emotional expression can be improved by various intervention techniques that in turn can help them understand and respond more appropriately to other people. Problems in the area on emotional reciprocity among individual with ASD involve recognizing, understanding, expressing, and regulating emotions. Their ability in emotional reciprocity is often improved with a comprehensive treatment approach, especially by focused emotional enhancement intervention. In this review, we followed the standard IMRAD (Introduction, Methods, Results, and Discussion) structure to critically examine the condition of autism and its relation with genetic mechanism, and how theories of emotion and theory of mind associated with persons with ASD, some of the widely used assessment tools and future research direction in the emotional development of individuals diagnosed with ASD by using the narrative review method. Records collected through research databases such as Scopus, PubMed, Web of Science, Medline, EBSCO and published books with ISBN (International Standard Book Number), and published test manuals were evaluated in-depth and summarized based on the subtopic of the proposed title. A critical theoretical analysis of the genetic mechanism of emotions, theories of emotions, and theory of mind was explained in connection with ASD.

OBJECTIVES/SPECIFIC AIMS: Autism spectrum disorder (ASD) affects 1 in 68 people and includes restricted, repetitive behavior, and social communication deficits. Aspects of face processing (i.e., identity, emotion perception) are impaired in some with ASD. Neuroimaging studies have shown aberrant patterns of brain activation and connectivity of face processing regions. However, small sample sizes and inconsistent results have hindered clinical utility of these findings. The study aims to establish consistent patterns of brain responses to faces in ASD and provide directions for future research. METHODS/STUDY POPULATION: Neuroimaging studies were identified through a multi-database search according to PRISMA guidelines. In total, 23 studies were retained for a sample size of 383 healthy controls and 345 ASD. Peak coordinates were extracted for activation likelihood estimation (ALE) in GingerALE v2.3.6. Follow-up ALE analyses investigated directed Versus undirected gaze, static Versus dynamic, emotional Versus neutral, and familiar Versus unfamiliar faces. RESULTS/ANTICIPATED RESULTS: Faces produced bilateral activation of the fusiform gyrus (FG) in healthy controls (−42 −52 −20; 22 −74 −12, p<0.05, FDR) and left FG activation in ASD (−42 −54 −16, p<0.05, FDR). Activation in both groups was lateral to the mid-fusiform sulcus. Follow-up results pending. DISCUSSION/SIGNIFICANCE OF IMPACT: Reduced right FG activation to faces may inform biomarker or response to intervention studies. Mid-fusiform sulcus proved a reliable predictor of functional divides should be investigated on a subject-specific level.

Abstract Background Pregnancy can be a stressful time for many women; however, it is unclear if higher stress and depressive symptoms are associated with poorer diet quality during pregnancy. Objective The aims for this narrative review were to (1) synthesize findings of original, peer-reviewed studies that examined associations of stress and/or depressive symptoms with diet quality during pregnancy; (2) review the measurement tools used to assess stress, depressive symptoms, and diet quality; (3) identify current gaps in the extant literature; and (4) offer recommendations for future research. Methods A search strategy was used to identify peer-reviewed manuscripts published between January 1997 and October 2018, using the following databases: PubMed, CINAHL Complete, PsycINFO, Academic Search Complete, and Psychology & Behavioral Sciences Collection. The search was updated December 2019. Two reviewers independently assessed title, abstract, and full-text of the studies that met the inclusion criteria. Data were extracted and a quality assessment was conducted. Results Twenty-seven observational studies were identified in this review (21 cross-sectional and 6 longitudinal). In 22 studies, higher stress and/or depressive symptoms were associated with poorer diet quality or unhealthy dietary patterns; 5 studies found no association. Findings are mixed and inconclusive regarding the relationship among stress, depressive symptoms, and food groups related to diet quality and frequency of fast-food consumption. Conclusions The current data suggest stress and depressive symptoms may be a barrier to proper diet quality during pregnancy; however, variability in the assessment tools, timing of assessments, and use of covariates likely contribute to the inconsistency in study findings. Gaps in the literature include limited use of longitudinal study designs, limited use of comprehensive diet-quality indices, underrepresentation of minority women, and lack of multilevel theoretical frameworks. Studies should address these factors to better assess associations of stress and/or depressive symptoms with diet quality during pregnancy.

Abstract Background: Executive Functions (EFs) deficit in Autism spectrum disorder (ASD) has been mainly investigated, while less is known about the EFs in toddlers. The study aimed was to investigate the relationship between EFs deficits and repetitive and restricted behaviors (RRBs) in toddlers with ASD symptoms. Finally, we examined whether EFs deficits were predictive of RRBs.Method: Cross-sectional data were collected from mothers of forty-five toddlers under 36 months old. The modified checklist for autism in toddlers (M-CHAT). The Gilliam autism rating scale (GARS-2), the behavior rating inventory of executive functioning-preschool version (BRIEF-P), and repetitive behavior scale- revised (RBS-R) administered to mothers.Findings: We found significant associations between parent-reported executive functions problems and (1) stereotyped behaviors, (2) self-injurious behaviors, (3) ritualistic behaviors, (4) sameness behaviors, (5) restricted behaviors, (6) compulsive behaviors, and (7) repetitive behaviors total score. There was a lack of association between M-CHAT and social interactions deficits of GARS-2 and the repetitive behaviors total score. Increases in the degree of EFs deficits predicted increments in repetitive behaviors.Discussion: These results support a link between executive disfunction and RRBs. Future research on RRBs in ASD may benefit from focusing on specific executive functioning abilities rather than general categories.

Schizophrenia Spectrum Disorders

There is substantial data pointing to evidence of heightened rates of psychotic experiences and schizophrenia spectrum disorders in individuals with autism spectrum disorder (ASD). Given overlapping genetics and neurobiology between the two disorders, the prevalence of this comorbidity is not surprising. And yet, psychosis in ASD has received relatively little attention in either the scientific or the clinical literatures. Following an introduction to the shared historical context of schizophrenia and ASD, this chapter reviews the diagnostic criteria for psychosis and the assessment tools available for evaluating symptoms. Difficulties in differentiating true psychotic symptoms from several hallmark ASD features, as well as in diagnosing psychosis in minimally verbal individuals with ASD, are highlighted, and recommendations for making this diagnostic distinction are offered. With regard to treatment, there is a striking absence of literature addressing how to treat psychosis when it presents in individuals with ASD. This chapter highlights best practice treatments for childhood-onset and adult schizophrenia and related disorders and discusses how these treatments might apply or need adaptation when treating an individual with ASD. Finally, this chapter offers recommendations for future research regarding the nature, prevalence, developmental course, assessment, and most effective treatments for schizophrenia and other psychotic disorders when they present in individuals with ASD.

Children and adults with autism spectrum disorder are less accurate in facial emotion recognition, which is thought to contribute to impairment in social functioning. Although many interventions have been developed to improve facial emotion recognition, there is no consensus on how to best measure facial emotion recognition in people with autism spectrum disorder. This lack of agreement has led to wide variability in how facial emotion recognition is measured and, subsequently, inconsistent findings related to impact of intervention targeting facial emotion recognition impairment. The purpose of this review is to synthesize the extant research on measurement of facial emotion recognition in the context of treatment. We conducted an electronic database search to identify relevant, peer-reviewed articles published between January 1998 and November 2019 to identify studies evaluating change in facial emotion recognition in autism spectrum disorder. Sixty-five studies met inclusion criteria, utilizing a total of 36 different assessment measures for facial emotion recognition in individuals with autism spectrum disorder. Only six of the measures were used in multiple studies conducted by different investigative teams. The outcomes of the studies are reported and summarized with the goal of informing future research. Lay Abstract Children and adults with autism spectrum disorder show difficulty recognizing facial emotions in others, which makes social interaction challenging. While there are many treatments developed to improve facial emotion recognition, there is no agreement on the best way to measure such abilities in individuals with autism spectrum disorder. The purpose of this review is to examine studies that were published between January 1998 and November 2019 and have measured change in facial emotion recognition to evaluate the effectiveness of different treatments. Our search yielded 65 studies, and within these studies, 36 different measures were used to evaluate facial emotion recognition in individuals with autism spectrum disorder. Only six of these measures, however, were used in different studies and by different investigators. In this review, we summarize the different measures and outcomes of the studies, in order to identify promising assessment tools and inform future research.

Gi Symptoms

Background and objectives: Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired communication, social interaction disorder, and repetitive behavior. Dysbiotic gut microbiota (GM) could be a contributing factor to the appearance of ASD, as gastrointestinal (GI) symptoms are comorbidities frequently reported in ASD. As there is a lack of reviews about the role played by GM in the GI symptoms of ASD, this work aimed to carry out a systematic review of current studies comparing the GM of children with ASD and GI symptoms with those of healthy controls in the last six years. Materials and Methods: The systematic review was performed following the PRISMA guidelines. The databases chosen were Web of Science, Scopus, PubMed, and PsycINFO, and the keywords were (gut* OR intestine* OR bowel* OR gastrointestinal*) AND (microbiota* OR microflora* OR bacteria* OR microbiome* OR flora* OR bacterial* OR bacteria* OR microorganism* OR feces* OR stool*) AND (autistic* OR autism* OR ASD*). Results: A total of 16 articles were included. Ten articles performed correlations analysis between GI symptoms and ASD. Among those 10 articles, 7 found differences between the GI symptoms present in children with ASD and healthy controls. The most common GI symptom was constipation. Among the seven articles that found differences, three performed correlations analysis between GI symptoms and gut microbe abundance. Candida, Prevotella, Streptococcus, and Veillonella showed higher and lower abundance, respectively, in children with ASD and GI symptoms in more than one article. Bacteroidetes, Firmicutes, Actinomyces, Dorea, Lactobacillus, Faecalibacterium prausnitzii, and Bacteroidetes/Firmicutes ratios showed abundance discrepancies. Conclusions: It is still too early to draw a conclusion about the gut microbes involved in GI symptoms of ASD. Future research should consider the relationship between ASD behavior, GM, and GI symptoms in a multidisciplinary way and homogenize sample characteristics.

Early and objective autism spectrum disorder (ASD) assessment, as well as early intervention are particularly important and may have long term benefits in the lives of ASD people. ASD assessment relies on subjective rather on objective criteria, whereas advances in research point to up-to-date procedures for early ASD assessment comprising eye-tracking technology, machine learning, as well as other assessment tools. This systematic review, the first to our knowledge of its kind, provides a comprehensive discussion of 30 studies irrespective of the stimuli/tasks and dataset used, the algorithms applied, the eye-tracking tools utilised and their goals. Evidence indicates that the combination of machine learning and eye-tracking technology could be considered a promising tool in autism research regarding early and objective diagnosis. Limitations and suggestions for future research are also presented.

Sustainability Assessment Tools

Over the past years, an increasing number of initiatives was considered to address emerging global sustainability issues. Sustainability assessment tools were the most commonly applied methodologies towards measuring sustainability performance. There are a number of assessment tools and techniques for sustainable development. This article aims at identifying the various sustainability assessment tools at country level taking into consideration the integration of environmental, economic, and social dimensions. The target of this paper is to compare the various sustainability measurement techniques and their characteristics using evaluation criteria. The outcome of this analysis is used to direct and clarify researchers and practitioners on sustainability assessment at country level, more specifically in developing countries. The focus of the paper rests on the Brundtland Report definition of sustainable development. The work was carried out using a bibliometric analysis approach based on Web of Science platform from the period 2000 to 2020. There was tremendous works which were conducted on sustainability assessment during the last two decades. The comparative analyses show the research gap among the various tools with respect to the criteria they satisfied. The research discussion suggests that a sustainability assessment framework for Small Island Developing States (SIDS) is identified as a future research direction.

P50 Suppression

Abstract. Auditory sensory gating is commonly assessed using the Paired-Click Paradigm (PCP), an electroencephalography (EEG) task in which two identical sounds are presented sequentially and the brain’s inhibitory response to the second sound is measured. Many clinical populations demonstrate reduced P50 and/or N100 suppression. Testing sensory gating in children may help to identify individuals at risk for neurodevelopmental disorders earlier, including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), which could lead to more optimal outcomes. Minimal research has been done with children because of the difficulty of performing lengthy EEG experiments with young children, requiring them to sit still for long periods of time. We designed a modified, potentially child-friendly version of the PCP and evaluated it in typically developing adults. The PCP was administered twice, once in a traditional silent room (silent movie condition) and once with an audible movie playing (audible movie condition) to minimize boredom and enhance behavioral compliance. We tested whether P50 and N100 suppression were influenced by the presence of the auditory background noise from the movie. N100 suppression was observed in both hemispheres in the silent movie condition and in the left hemisphere only during the audible movie condition, though suppression was attenuated in the audible movie condition. P50 suppression was not observed in either condition. N100 sensory gating was successfully elicited with an audible movie playing during the PCP, supporting the use of the modified task for future research in both children and adults.
