EXPRESS: Distinct abilities associated with matching same identity faces vs. discriminating different faces: Evidence from individual differences in prosopagnosics and controls

Previous face matching studies provide evidence that matching same identity faces (match trials) and discriminating different face identities (non-match trials) rely on distinct processes. For example, instructional studies geared towards improving face matching in applied settings have often found selective improvements in match or non-match trials only. Additionally, a small study found that developmental prosopagnosics (DPs) have specific deficits in making match but not non-match judgments. In the current study, we sought to replicate this finding in DPs and examine how individual differences across DPs and controls in match vs. non-match performance relate to featural vs. holistic processing abilities. 43 DPs and 27 controls matched face images shown from similar front views or with varied lighting or viewpoint. Participants also performed tasks measuring featural (eyes/mouth) and holistic processing (part-whole task). We found that DPs showed worse overall matching performance than controls and that their relative match vs. non-match deficit depended on image variation condition, indicating that DPs do not consistently show match- or non-match-specific deficits. When examining the association between holistic and featural processing abilities and match vs. non-match trials in the entire group of DPs and controls, we found a very clear dissociation: Match trials significantly correlated with eye processing ability (r=.48) but not holistic processing (r=.11), whereas non-match trials significantly correlated with holistic processing (r=.32) but not eye processing (r=.03). This suggests that matching same identity faces relies more on eye processing while discriminating different faces relies more on holistic processing.

Learning from Programming Robots

Oftentimes, elementary students are not provided with rich, investigative lessons that support computation thinking (CT) and critical analysis through the use of tools. The purpose of this study was to explore how programming educational robotics (ERs) support third grade gifted students' CT skills in the context of Taxicab geometry focusing on data processing abilities and time estimation skills. Using qualitative case study methodology, data were gathered though classroom interviews, observations and document analyses. Results indicated that ERs provided students with opportunities for both learning programming in early grades and applying mathematical knowledge and skills through a meaningful task that supported content commonly emphasized in mathematics. Specifically, there was growth in student understanding in terms of abstraction, decomposition, algorithmic thinking, evaluation, and generalization. The findings also suggested that working with ERs supported students' estimation and data processing skills. Implications are provided for the integration of ERs as a tool for primary gifted students' learning of mathematics in technology-mediated environments emphasizing CT.

Navigating Accent Variation: A Developmental Perspective

Adult processing of other-accented speech is fast, dependent on lexical access, and readily generalizable to new words. But what does children's processing of other-accented speech look like? Although many acquisition researchers have emphasized how other-accented speech presents a formidable challenge to young children, we argue that the field has perhaps underestimated children's early accent processing abilities. In support of this view, we present evidence that 2-year-olds’ accent processing abilities appear to be in many respects adult-like, and discuss the growing literature on children's ability to cope with multi-accent input in the natural world. We outline different theoretical outlooks on the transition children make from infancy to later childhood, and discuss how the growing sophistication of infants’ accent processing abilities feeds into their social perception of the world (and perhaps vice versa). We also argue that efficient processing and meaningful interpretation of accent variation are fundamental to human cognition, and that early proficiency with accent variation (along with all of the implied representational and learning capacities) is difficult to explain without assuming the early emergence of abstract speech representations. Expected final online publication date for the Annual Review of Linguistics, Volume 8 is January 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Transdiagnostic Patterns of Sensory Processing in Autism and ADHD

Sensory processing abilities are highly variable within and across people diagnosed with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). This study examined the transdiagnostic nature of sensory processing abilities, and their association with features of ASD and ADHD, in a large sample of autistic people (n = 495) and people with ADHD (n = 461). Five similar data-driven sensory phenotypes characterized sensory processing abilities, and showed similar patterns of association with features of ASD and ADHD, across both diagnostic groups. These results demonstrate the transdiagnostic nature of sensory processing abilities, while contributing to a growing body of literature that suggests the ASD and ADHD diagnostic labels have poor explanatory power.

Biblical Portrayal of Ethiopia as a Challenge to Western Perspectives of Africa

Africa has been presented as underdeveloped and backward until the adventure of colonial architects. Archaeological remnants and structures, some of which are still standing to date, portray a different reality seemingly echoed by the biblical account. The endowment of Africa with natural resources, evidence of processing abilities and references to established kingdoms occasionally used as instruments of divine punishment of Israel or provision of refuge suggests a much more advanced situation than has been routinely presented by historians. The biblical record which has been proven for its reliability and historicity provides us with the impetus to re-analyse key texts in order to re-examine the views that have been posited. The Western tendency to undermine Africa's advancements is well known. This article therefore considers the story of the Ethiopian Eunuch as a point of reference to African realities reflected throughout the biblical text.

Sensory Processing as a Predictor of Leisure Participation in Early Adolescents

Sensory processing may be associated with adolescents’ preferences for different leisure activities. However, knowledge about how different sensory processing patterns may relate to adolescents’ participation in leisure activities is scarce. This study sought to investigate the relationship between sensory processing and leisure participation in early adolescents. Study participants were typical early adolescents aged from 11 to 12 years (mean = 11.88 ± 0.33, n = 140). The Adolescent/Adult Sensory Profile (AASP) and Children’s Assessment for Participation and Enjoyment (CAPE) were used to determine the participants’ sensory processing abilities. Correlational and multiple regression methods were employed to analyze the relationship between sensory processing and leisure participation. There were significant positive relationships between sensory seeking and participation (r = 0.177–0.350, p = 0.000–0.037). There were also significant negative relationships between low registration, sensory sensitivity, and overall participation (r = −0.202, p = 0.017, r = −0.212, p = 0.012). We found that formal activities, skill-based activities, and self-improvement activities were the main distinguishing factors between sensory processing types. Results suggest that sensation seeking and sensory sensitivity from the AASP were predictive of leisure participation. This study provides evidence to inform practices regarding the association of sensory processing and leisure participation and supports the need for assessing sensory processing in early adolescents.

Visual occipito-temporal sensitivity to digits through elementary school

Number processing abilities are important for academic and personal development. The course of initial specialization of ventral occipito-temporal cortex (vOTC) for visual number processing is crucial for the development of numeric and arithmetic skills. We examined the visual N1, the electrophysiological correlate of vOTC activations across five time points in kindergarten (T1), middle and end of first grade (T2, T3), second (T4) and fifth grade (T5). 62 children (35 female) performed a target detection task which included visual presentation of digits, false fonts, and letters. Arithmetic skills were measured at T4 and T5 with standardized math tests. Stronger N1 amplitudes for digits than false fonts were found across all 5 measurements. Arithmetic skills correlated negatively with visual N1 sensitivity to digits at T4 (2nd grade, mean age 8.3 yrs) over the left hemisphere, possibly reflecting allocation of more attentional or cognitive resources with poorer arithmetic skills. Our main result shows persistent visual N1 sensitivity to digits that is already present early on in pre-school and remains stable until fifth grade. This differs from the relatively sharp rise and fall of the visual N1 sensitivity to words or letters between kindergarten and middle of elementary school. The present study thus indicates different trajectories in the development of visual processing for written characters that are relevant to numeracy and literacy.

Speech Perception in Noise Predicts Oral Narrative Comprehension in Children With Developmental Language Disorder

We examined the relative contribution of auditory processing abilities (tone perception and speech perception in noise) after controlling for short-term memory capacity and vocabulary, to narrative language comprehension in children with developmental language disorder. Two hundred and sixteen children with developmental language disorder, ages 6 to 9 years (Mean = 7; 6), were administered multiple measures. The dependent variable was children's score on the narrative comprehension scale of the Test of Narrative Language. Predictors were auditory processing abilities, phonological short-term memory capacity, and language (vocabulary) factors, with age, speech perception in quiet, and non-verbal IQ as covariates. Results showed that narrative comprehension was positively correlated with the majority of the predictors. Regression analysis suggested that speech perception in noise contributed uniquely to narrative comprehension in children with developmental language disorder, over and above all other predictors; however, tone perception tasks failed to explain unique variance. The relative importance of speech perception in noise over tone-perception measures for language comprehension reinforces the need for the assessment and management of listening in noise deficits and makes a compelling case for the functional implications of complex listening situations for children with developmental language disorder.
