ABC-CT Pre-School Feasibility Study

The N170 Latency to Upright Human Faces (N170 latency) is a scalp recorded EEG event-related potential (ERP) component elicited by perception of the upright human face. Recorded over the posterior-temporal right hemisphere, the latency (or speed) of the peak of the N170 ERP component occurs at approximately 200 msec in children aged 6 to 11 years of age and will be later in 3 to 5 year old children.

Onscreen gaze position data, reflected in percentage of foveation (angling of the eyes to focus on a particular object) to human faces (Face%) relative to total valid foveation time across three assays.

The Aberrant Behavior Checklist (ABC) is a symptom checklist for assessing problem behaviors of children and adults with neurodevelopmetnal disorder at home, in residential facilities, ICFs/MR, and work training centers. It is also useful for classifying problem behaviors of children and adolescents with neurodevelopmetnal disorder in educational settings, residential and community-based facilities, and developmental centers

The Autism Impact Measure (AIM) uses a 2-week recall period with items rated on two corresponding 5-point scales (frequency and impact)

The Behavior Assessment System for Children, Third Edition (BASC-3) offers several different forms designed to aid in collecting information regarding at-risk adaptive behavioral and/or emotional problems.

The PDD-BI is an assessment tool for children on the autism spectrum. PDDBI profiles can provide guidance to clinicians regarding the child's problems as perceived by the informants, how a particular child compares to most children their age with ASD, and the skills and abilities of the child.

The Social Responsiveness Scale 2 (SRS-2) is completed in just 15 to 20 minutes and identifies social impairment associated with autism spectrum disorders (ASDs) and quantifies its severity.

Differential Ability Scales - Second Edition; DAS-II (Elliott C, 2007): The DAS-II is a clinical instrument designed to assess cognitive ability include variables such as verbal cluster, spatial cluster, nonverbal cluster, special nonverbal composite

Resting State EEG (Eyes Open) provides a reference for the event-related EEG measures and a baseline biomarker of EEG spectral power across frequencies, neurofunctional connectivity and coherence, and hemispheric asymmetry and will always be done prior to the other EEG paradigms. Participants will be presented with non-social, abstract moving videos in random order.

Faces processing is a foundation for social perception and attention and serves as a promising and robust biomarker of social impairment in ASD and a potential index of subgroup differences. As the primary non-resting paradigm, the FACES task will always

The Kaufman Assessment Battery for Children (KABC) is a clinical instrument (psychological diagnostic test) for assessing cognitive development. Its construction incorporates several recent developments in both psychological theory and statistical methodology.

The Emotional Competence Inventory 2.0 (ECI) measures 18 competencies organized into four clusters: Self-Awareness, Self-Management, Social Awareness, and Relationship Management. The Emotional Competence Inventory takes approximately 30-45 minutes to complete.

Mullen Scales of Early Learning is a developmentally integrated system that assesses language, motor, and perceptual abilities, measures cognitive ability and motor development quickly and reliability.

Administered in person visit or via parent phone interview. The Socialization score is based on 3 subdomains of Interpersonal Relationships, Play & Leisure, Coping Scales. The V-Scaled scores, which are specifically designed to measure change over time, are only available for the subdomains. The primary norm-referenced scores for the subdomains are v-scale scores, which have a mean of 15 and standard deviation (SD) of 3. The Vineland-3 is a standardized measure of adaptive behavior--the things that people do to function in their everyday lives.

ET Paradigms will be administered in counterbalanced blocks, one on each day of each screening or study visits. Both blocks will include all the tasks but in different orders. The length of individual paradigms ranges from 1 to 8.5 mins. Color images depicting 12 different female faces with direct gaze and the same faces with averted gaze will be presented. Twelve different exemplars from each of five categories (alarm clocks, mobile phones, birds, cars, and shoes) will be used as distracters. Twelve different slides will each contain six images (one face and five distracters, one from each category) placed at an equal distance from the center of the screen. Each slide contains a different set of six images, each image being shown only once in the experiment. This measure examines scanning patterns towards arrays of objects, synthetic stimuli, and faces as well as towards more complex naturalistic (static) scenes. This task examines complex scene processing and attentional selection.

ET Paradigms will be administered in counterbalanced blocks, one on each day of each screening or study visits. Both blocks will include all the tasks but in different orders. The length of individual paradigms ranges from 1 to 8.5 mins.

Pupillary Light Reflex (PLR) Task is measured following a stimuli that consist of a central fixation point on a black background that flashes white for 133 milliseconds. The constriction of the pupil in response to a bright flash indexes function of the parasympathetic nervous system.

ET Paradigms will be administered in counterbalanced blocks, one on each day of each screening or study visits. Both blocks will include all the tasks but in different orders. The length of individual paradigms ranges from 1 to 8.5 mins.

Interactive Social Task (IST) is taps similar constructs as the activity monitoring task in a more naturalistic, dynamic, and complex context. Following a central fixation, children will be presented with interactive social trails in which two children engage in a natural interactive play session.

ET Paradigms will be administered in counterbalanced blocks, one on each day of each screening or study visits. Both blocks will include all the tasks but in different orders. The length of individual paradigms ranges from 1 to 8.5 mins.

Activity Monitoring Task is measured following central fixation. Children will be presented with multiple activity monitoring trails depicting two actresses engaging in a controlled joint activity such as assembling a puzzle.

Visual Evoked Potentials (VEPs) index low-level visual processing and reflect the functional integrity of the visual pathway. VEPs reflect excitatory (glutamatergic) and inhibitory (GABAergic) activity and may index subgroups of ASD with low-level visual impairments. VEPs also serve as a control for assessment of higher-order activity in social visual paradigms. Subjects will be presented with black and white checkerboards that reverse phase at a defined interval. The order of the VEP and Biomotion paradigms will be counterbalanced.

(CSI-4) is a behavior rating scale for evaluating the symptoms of DSM-IV and DSM-5 emotional and behavioral disorders among children between 5 and 12 years old who are attending elementary school (kindergarten thru 6th grade). There are both parent- and teacher-completed versions. The CSI-4: Parent Checklist contains 97 items for over a dozen emotional and behavioral disorders, and the CSI-4: Teacher Checklist contains 77 items. The CSI-4 can be scored to derive symptom count cutoff scores (diagnostic model) or symptom severity scores (T scores based on a dimensional model). Scoring is quick and easy with user-friendly score sheets.
