What is typical: Atypical in young children's attention regulation?: Characterizing the developmental spectrum with the Multidimensional Assessment Profiles-Attention Regulation Infant-Toddler (MAPS-AR-IT) Scale.

While attention dysregulation is a promising early indicator of neurodevelopmental risk, in particular attention-deficit/hyperactivity disorder (ADHD), it is difficult to characterize clinical concern due to its developmental expectability at the transition to toddlerhood. Thus, explicating the typical:atypical continuum of risk indicators is among the key future directions for research to promote early identification and intervention, and prevent decrements in the attainment of developmental milestones into early childhood. In this paper, we present the Multidimensional Assessment Profiles-Attention Regulation Infant-Toddler (MAPS-AR-IT) Scale, a novel parent-report survey of dimensional, developmentally specified indicators of attention (dys)regulation. Item Response Theory was employed to characterize the typical:atypical spectrum of both normative and more concerning dysregulation (including the contexts in which behavior occurs). We provide evidence of the validity of this measure in capturing the full typical:atypical spectrum via a longitudinal sample of typically developing children at 12-18 months of age (baseline) via concurrent scores on well-validated temperament and clinical measures. We also examine longitudinal stability and predictive validity if the MAPS-AR-IT via a clinical interview of ADHD symptoms at 24-30 months (follow-up). While not diagnostic, we present evidence of the utility of the MAPS-AR-IT in explicating individual neurodevelopmental risk and elucidating the broader typicality of behaviors related to attention (dys)regulation.

Aunque la desregulación de la atención es un prometedor indicador temprano del riesgo neural de desarrollo, en particular el trastorno de déficit en la atención/hiperactividad (ADHD), es difícil caracterizar las preocupaciones clínicas debido al factor de expectativa de desarrollo al momento de la transición a la temprana niñez. De manera que explicar la progresión típica:atípica de indicadores de riesgo está entre las futuras directrices claves para la investigación con el fin de promover la temprana identificación e intervención, y prevenir disminuciones en el alcance de hitos críticos hacia la temprana niñez. En este ensayo, presentamos la Escala de Perfiles de Evaluación Multidimensional - Regulación de la Atención del Infante-Niño Pequeñito (MAPS-AR-IT) una novedosa encuesta de reporte del progenitor, acerca de la (des)regulación de la atención, dimensional y específica para el desarrollo. Aportamos evidencia de la validez de esta medida para captar la completa gama típica:atípica por medio de una muestra longitudinal de niños típicamente en desarrollo, a los 12-18 meses de edad (edad base) por medio de puntajes concurrentes sobre el temperamento bien validado y las medidas clínicas, así como también la estabilidad longitudinal y la validez de predicción por medio de una entrevista clínica de síntomas de ADHD a los 24-30 meses (seguimiento). Se empleó la Teoría de Respuesta al Asunto para caracterizar la gama típica:atípica tanto de la desregulación normativa como de la más preocupante (incluyendo los contextos en los cuales ocurre el comportamiento). Aunque no se trata de diagnóstico, presentamos evidencia de la utilidad de MAPS-AR-IT para explicar el riesgo individual de desarrollo neural y elucidar el más amplio aspecto típico de comportamientos relacionados con la (des)regulación de la atención.

Bien que la dysrégulation de l'attention soit un indicateur précoce prometteur du risque neurodéveloppemental, en particulier le trouble déficitaire de l'attention/hyperactivité (TDHA) il est difficile de caractériser la préoccupation clinique du fait de sa prévisibilité développementale à la transition à la petite enfance. Par conséquent, expliquer le continuum typique:atypique des indicateurs de risque s'avère être une des directions futures de recherches clé pour promouvoir l'identification et l'intervention précoce, et prévenir les baisses dans la réalisation d'étapes développementales importantes jusque dans la petite enfance. Dans cet article nous présentons l'Echelle Multidimensional Assessment Profiles - Attention Regulation Infant-Toddler (MAPS-AR-IT) (échelle de profils d'évaluation multidimensionnelle - régulation de l'attention bébé-petit enfant, abrégée selon l'anglais MAP-AR-IT), une étude nouvelle basée sur les rapports faits par les parents de la (dys)régulation de l'attention dimensionnelle et spécifiée selon le développement. Nous démontrons la validité de cette mesure en capturant l'éventail total typique:atypique au moyen d'un échantillon longitudinal d'enfants se développement typiquement, à 12-18 mois (ligne de case) au moyen de scores concurrents de mesures cliniques et de tempérament bien validées, ainsi qu''une stabilité longitudinale et d'une validité prédictive au moyen d'un entretien Clinique des symptômes THHA à 24-30 mois (suivi). La Item Response Theory (IRT) a été employée pour caractériser l'éventail typique:atypique de la dysrégulation à la fois normative et celle plus inquiétante (y compris les contextes dans lesquels le comportement prend place). Bien que cela ne soit pas diagnostique, nous présentons la preuve de l'utilité de la MAPS-AR-IT en expliquant le risqué neurodéveloppemental individuel et en élucidant la typicalité plus large de comportements liés à la (dys)régulation de l'attention.

Developmental Trajectories of Irritability across the Transition to Toddlerhood: Associations with Effortful Control and Psychopathology.

Preschool-age irritability is a transdiagnostic marker of internalizing and externalizing problems. However, researchers have generally been reluctant to examine irritability within a clinically salient framework at younger ages due to some instability during the "terrible twos" period. Developmentally sensitive and dense measurements to capture intra- and inter-individual variability, as well as exploration of developmental processes that predict change, are needed. This study aimed to examine (1) the trajectories of irritability at the transition to toddlerhood (12-24 months of age) using repeated measures, (2) whether effortful control was associated with individual differences in level and growth rate of irritability, and (3) whether individual differences in the irritability trajectories were associated with later psychopathology. Families were recruited when the child was 12-18 months old (N = 333, 45.65% female). Mothers reported on their toddler's irritability at baseline and every two months until a follow-up laboratory assessment approximately one year later. Effortful control was measured at baseline. Clinical internalizing/externalizing symptoms were measured at the follow-up assessment. Hierarchical linear models revealed an increase in irritability over time, yet there was relatively little within-person variability. Effortful control was only associated with the level of irritability and not growth rate. Level of irritability was associated with internalizing, externalizing, and combined symptoms, but growth rate was not. Findings suggest intraindividual stability in irritability at the transition to toddlerhood and the possibility that screening for elevated irritability at toddler age is meaningful.

Using SCENTinel® to predict SARS-CoV-2 infection: insights from a community sample during dominance of Delta and Omicron variants.

Introduction: Based on a large body of previous research suggesting that smell loss was a predictor of COVID-19, we investigated the ability of SCENTinel®, a newly validated rapid olfactory test that assesses odor detection, intensity, and identification, to predict SARS-CoV-2 infection in a community sample. Methods: Between April 5, 2021, and July 5, 2022, 1,979 individuals took one SCENTinel® test, completed at least one physician-ordered SARS-CoV-2 PCR test, and endorsed a list of self-reported symptoms. Results: Among the of SCENTinel® subtests, the self-rated odor intensity score, especially when dichotomized using a previously established threshold, was the strongest predictor of SARS-CoV-2 infection. SCENTinel® had high specificity and negative predictive value, indicating that those who passed SCENTinel® likely did not have a SARS-CoV-2 infection. Predictability of the SCENTinel® performance was stronger when the SARS-CoV-2 Delta variant was dominant rather than when the SARS-CoV-2 Omicron variant was dominant. Additionally, SCENTinel® predicted SARS-CoV-2 positivity better than using a self-reported symptom checklist alone. Discussion: These results indicate that SCENTinel® is a rapid assessment tool that can be used for population-level screening to monitor abrupt changes in olfactory function, and to evaluate spread of viral infections like SARS-CoV-2 that often have smell loss as a symptom.

Brains over beauty: A preregistered test of the effects of objectification on women's cognitive performance.

The present study was a preregistered, well-powered experimental test of findings related to the effect of state self-objectification and anticipation of the sexualized male gaze on women's cognitive performance. College women (n = 407) performed a working memory task in one of three randomly assigned conditions. In the experimental conditions (self-objectification and male gaze), women completed the task while being video recorded from the neck down. In the male gaze condition, participants were told their videos would later be evaluated by men as part of a separate dating study. Women in the control condition were not video recorded. Results indicated women experienced a moderate increase in state self-objectification in both experimental conditions. However, compared to the control condition, women in the experimental conditions did not show reduced performance on the working memory task (in either latency or accuracy), decreases in body satisfaction, or increases in negative mood. Across conditions, state self-objectification was not associated with accuracy or latency on the working memory task. Mixed findings concerning objectification's effect on cognitive performance may be attributed to variability in experimental manipulations and dependent variables employed in this area of research.

These Boots Weren't Made for Walking: Gendered Discrepancies in Wearing Painful, Restricting, or Distracting Clothing.

Using the framework of objectification theory (Fredrickson & Roberts in Psychology of Women Quarterly 21(2): 173-206, 1997), the current studies explored how often women (vs. men) reported wearing clothing that is painful, distracting, and/or restricting (PDR clothing). Additionally, we examined differences in body surveillance (i.e., chronically monitoring the appearance of one's body) and body appreciation between those who reported wearing various types of PDR clothing and those who did not. In both a sample of U.S. college students (n = 545) and a broader sample of U.S. adults (n = 252), results indicated that women were substantially more likely to wear PDR clothing than men. Across both samples, the largest differences between men and women were in wearing uncomfortable or painful shoes and in wearing clothing that is distracting because it requires ongoing monitoring or adjusting. Women and men with higher body surveillance were more likely to report wearing PDR clothing. Though some findings pointed toward a negative association between body appreciation and wearing PDR clothing, these results were inconsistent. Overall, results were consistent with the notion that the gendered nature of clothing might reflect and provoke chronic vigilance of the body's appearance. Gendered differences in the extent to which clothing promotes comfort and movement vs. discomfort and distraction has clear implications for women's quality of life.

Compared to Facebook, Instagram use causes more appearance comparison and lower body satisfaction in college women.

The current experiment tested the effect of social media use on college women's appearance comparisons, mood, and body satisfaction. We randomly assigned 308 undergraduate women (aged 18-26) to use Facebook, use Instagram, or play a matching game (the control condition) on an iPad for seven minutes. Compared to the Facebook condition, Instagram users retrospectively reported spending more time viewing images or videos containing people. Participants in both the Facebook and Instagram conditions also retrospectively reported engaging in more appearance comparisons relative to those in the control condition, but Instagram users reported significantly more appearance comparisons than those in the Facebook condition. Those who used Instagram, but not Facebook, showed decreased body satisfaction, decreased positive affect, and increased negative affect. Results are consistent with previous research suggesting social media use influences body satisfaction and social comparison, and that Instagram may be a particularly harmful platform when it comes to body image because of its focus on photos over text.
