Understanding Turan: A Developmental Profile for Early Childhood Educators and Caregivers

Turan is a 24-month-old toddler enrolled in an inclusive early childhood program in Portland, Oregon. He presents with global developmental delay confirmed by Bayley Scales of Infant and Toddler Development, Fourth Edition (Bayley-4) results: Cognitive 68 (1st percentile), Language Composite 59 (0.1st percentile), and Motor Composite 72 (3rd percentile). His expressive vocabulary consists of 12 words—"mama," "dada," "uh-oh," "ball," "car," "bye," "more," "up," "no," "yes," "eat," and "dog"—all produced with inconsistent intelligibility (approximately 40% intelligible to unfamiliar listeners per speech-language pathologist report dated March 2024). Turan avoids eye contact during verbal exchanges >70% of the time, shows tactile defensiveness to denim textures and wet sand, and engages in rhythmic rocking for up to 12 minutes when overstimulated. This article synthesizes clinical data, peer-reviewed research, and field-tested interventions to support educators and caregivers working with children like Turan—offering actionable, developmentally grounded strategies without jargon or speculation.

Developmental Assessment Data and Diagnostic Context

Turan’s developmental profile emerged from multidisciplinary evaluation conducted at Oregon Health & Science University (OHSU) Doernbecher Children’s Hospital in February 2024. The Bayley-4 was administered across three domains using standardized protocols: Cognitive (subtests: Habituation, Visual Preference, Object Permanence, Imitation); Language (Receptive Communication, Expressive Communication); and Motor (Fine Motor, Gross Motor). His Cognitive Scale Score of 68 reflects significant difficulty sustaining attention to novel stimuli beyond 18 seconds on average and limited spontaneous problem-solving—e.g., he did not retrieve a toy hidden under one of two identical cloths during the object permanence task after four demonstrations.

Language assessment revealed receptive understanding of approximately 30–35 single-word directives in low-distraction settings (e.g., “Give me the cup,” “Clap hands”), but comprehension dropped to <15 words in group settings with background noise exceeding 55 dB (measured via SoundMeter Pro app calibrated to ANSI S1.4-2014 standards). Expressive language included only the 12 words noted previously, with no two-word combinations observed across 12 hours of naturalistic observation across home and center settings. His vocalizations were predominantly vowel-based (e.g., /a/, /o/, /ee/) with minimal consonant-vowel alternation.

Screening and Differential Considerations

The Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) yielded a high-risk score of 9/20 on initial screening and confirmed risk after follow-up interview, prompting referral to OHSU’s Autism Spectrum Disorder (ASD) diagnostic team. However, comprehensive ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition) administration resulted in a non-autism classification (ADOS-2 Module 1 Total Score = 5; cutoff for ASD = 7). Clinicians instead identified features consistent with Developmental Language Disorder (DSM-5 code 315.32) and Sensory Processing Disorder (SPD), specifically Sensory Modulation Disorder—Over-Responsivity subtype. No genetic anomalies were detected on chromosomal microarray (CMA) testing.

Standardized sensory assessment using the Sensory Processing Measure–Preschool (SPM-P) indicated clinically significant scores in the Auditory Processing (T-score = 74), Tactile Processing (T-score = 81), and Social Participation (T-score = 79) subscales. These findings align with Turan’s observed avoidance of noisy environments (e.g., cafeteria, music circle), refusal to wear jeans or fleece-lined jackets, and limited initiation of joint attention bids (<2 per 30-minute observation).

Evidence-Based Responsive Interaction Strategies

Effective engagement with Turan requires shifting from language-demanding to action-based reciprocity. Research by Girolametto et al. (2002) demonstrates that responsive interaction—defined as contingent, timely, and affectively matched responses to child-initiated behaviors—increases vocalizations in toddlers with language delays by 3.2x over 12 weeks compared to directive instruction. For Turan, this means responding to his gaze toward a rolling ball not with “What is it?” but with “Ball! *rolls ball slowly toward him*” while matching his vocalization (“ba!”) with exaggerated lip movement and rising intonation.

Three core principles guide all interactions: (1) Wait time ≥5 seconds after any prompt or pause; (2) Follow his lead—even if it’s staring at ceiling tiles or tapping a wooden block rhythmically—for at least 30 seconds before joining; (3) Use only one communication symbol (e.g., sign, picture, gesture) paired with one spoken word per exchange. In practice, staff use the Picture Exchange Communication System (PECS) Phase I protocol with laminated, Velcro-backed icons sized 3.5 × 3.5 inches (LinguiSystems brand). Turan successfully exchanged “eat,” “more,” and “break” icons for desired items in 82% of opportunities during structured snack routines over four weeks.

Visual Supports and Environmental Design

Visual structure reduces cognitive load and supports predictability—critical for children with low working memory capacity. Turan’s daily schedule uses 4 × 4 inch photo-based icons mounted on a 12-inch-wide felt board with color-coded sections: blue for arrival/routine, green for outdoor play, yellow for snack, red for transition times. Each icon includes a brief descriptive label in 18-pt Arial font (e.g., “Wash Hands → Soap + Water”) placed 1 inch below the image. Staff change the sequence daily but maintain consistent color coding and physical location of the board (mounted at 32 inches from floor—within Turan’s visual field at seated height).

Environmental modifications target sensory regulation. Acoustic panels (AcoustiGuard Pro 1200 series, NRC rating 0.85) were installed above the rug area to reduce reverberation time from 1.9 sec to 0.7 sec. Floor cushions are filled with shredded memory foam (density: 2.8 lb/ft³) rather than polyester fiberfill to provide deep-pressure input during seated activities. Lighting uses Philips Hue White Ambiance bulbs set to 2700K (warm white) and dimmed to 45% intensity—avoiding fluorescent fixtures that emit 120-Hz flicker detectable by children with visual hypersensitivity.

Motor Skill Development and Adaptive Equipment

Turan’s gross motor skills fall at the 12-month level per Bayley-4 norms: independent walking achieved at 18 months, but he lacks stair negotiation (requires hand-over-hand assistance on 3-step unit), cannot jump with both feet, and demonstrates asymmetrical weight-bearing during squat-to-stand transitions (left leg bears 72% of load per force plate analysis). Fine motor performance includes palmar raking for small objects but no pincer grasp; he transfers blocks using a fist grip and stacks only two 1.5-inch wooden cubes (standard size: Melissa & Doug Jumbo Building Set).

Occupational therapy (OT) sessions twice weekly focus on proximal stability to support distal skill emergence. Interventions include prone-on-elbows positioning on a therapy wedge (Therapy Shoppe Wedge, 25° incline) for 3 minutes daily to activate scapular stabilizers, followed by bilateral manipulation of textured balls (Tobbles Neo, diameter 3.5 inches, surface texture: medium nubs). Progress is tracked using the Peabody Developmental Motor Scales, Second Edition (PDMS-2): Over 8 weeks, his Stationary subtest raw score increased from 4 to 9 (equivalent to 14-month developmental age).

Feeding and Oral-Motor Integration

Oral-motor challenges contribute significantly to Turan’s communication limitations. Videofluoroscopic swallow study (VFSS) at OHSU confirmed delayed initiation of pharyngeal swallow and reduced tongue lateralization. He accepts only smooth purees (Stage 1 Gerber Organic Applesauce, viscosity measured at 1,200 cP using Brookfield DV2T viscometer) and soft solids cut into ¼-inch cubes (e.g., boiled carrot, banana). He gags on foods requiring rotary chewing or lateral tongue movement, such as shredded cheese or cooked peas.

Speech-language pathologist (SLP)-guided oral-motor exercises occur daily during snack: 2 minutes of chewing on a Z-Vibe® Bite Tube (medium resistance, blue tip) followed by 1 minute of lip compression against a chewy tube (ARK Grabber XXT). These protocols are drawn from the Beckman Oral Motor Protocol and implemented with fidelity verified via biweekly video coding (inter-rater reliability κ = 0.91). After 6 weeks, Turan increased bite acceptance from 3 to 11 bites per meal and reduced gagging incidents from 8.3 to 1.2 per session.

Collaborative Family Partnership Practices

Sustained progress hinges on consistency between home and center. Turan’s mother, Aisha, participates in weekly 20-minute video coaching sessions using the Hanen Program’s “More Than Words” framework. During these sessions, she records 5-minute segments of natural play (e.g., bath time, book sharing) which are coded for responsive behaviors using the Caregiver Interaction Scale (CIS). Baseline CIS scores showed low responsiveness (mean = 2.1/5); after 7 weeks, her mean score rose to 4.3/5, correlating with Turan’s increase in vocal attempts from 4.2 to 11.6 per hour (observed across 15-minute samples).

Home materials are provided in bilingual format (English/Arabic) using simplified syntax and pictorial step-by-step guides. For example, a laminated “Toothbrushing Routine” card shows five photos: (1) toothpaste pea-sized dot (Colgate Kids Cavity Protection, 1,100 ppm fluoride), (2) brush bristles angled 45°, (3) small circular motions on front teeth, (4) spitting into sink, (5) rinsing cup. Each photo is paired with ≤3 Arabic words (e.g., “افتح فمك” / “Open mouth”) and corresponding English translation printed in 24-pt font.

Data Tracking and Progress Monitoring

Progress is quantified using objective, frequency-based metrics—not subjective descriptors. Staff log data daily using a paper-based ABC (Antecedent-Behavior-Consequence) chart adapted for preverbal communication:

• Antecedent: Environmental condition (e.g., “music circle started,” “teacher said ‘clean up’”)
• Behavior: Observable action (e.g., “covered ears with palms,” “pointed to door,” “vocalized ‘ah’ for 2 sec”)
• Consequence: Adult response (e.g., “dimmed lights,” “gave choice board,” “mirrored sound + sign”)

This system captures patterns invisible to narrative notes. Over 22 days, data revealed that Turan vocalized within 5 seconds of receiving a preferred item (e.g., Thomas train) in 94% of trials—but only 11% of trials when handed a non-preferred item (e.g., plastic spoon). This informed a shift from “choice-making” prompts (“Do you want spoon or cup?”) to “action-based requests” (“Hand me cup” modeled with gesture).

Curriculum Adaptations Across Learning Domains

Standard curricula require intentional modification—not simplification—to ensure access. In literacy, Turan engages with the “Letter People” program (Zaner-Bloser) through tactile letter cards: each 4 × 4 inch card features a raised-letter outline (embossed depth: 0.025 inches) and a corresponding object (e.g., “B” with attached burlap swatch for “bear”). He traces letters with index finger while staff say the sound (/b/)—not the name (“bee”)—aligning with phonological awareness goals.

In math, he uses Learning Resources Snap Cubes (1-inch plastic cubes, 10 colors) for one-to-one correspondence. Instead of counting aloud, staff place one cube in his palm while saying “one,” wait for him to place it in a tray, then place second cube saying “two.” This builds procedural understanding before symbolic representation. After 10 sessions, he consistently placed 3 cubes in sequence (accuracy: 89%) versus baseline of 1 cube (accuracy: 33%).

Science exploration emphasizes sensory properties over naming. During “Sink or Float,” Turan manipulates objects weighted to standard densities: cork (0.24 g/cm³), pine wood (0.5 g/cm³), PVC pipe (1.3 g/cm³), and steel washer (7.8 g/cm³). Staff narrate cause-effect without labels: “Heavy thing goes down. Light thing stays up.” He now consistently pushes floating objects underwater and watches them rise—demonstrating emerging understanding of buoyancy.

Staff Training and Interdisciplinary Coordination

Effective implementation relies on coordinated professional development. All classroom staff completed 12 hours of training co-facilitated by OHSU’s Early Intervention Team and Portland State University’s Special Education Department. Modules covered: (1) Neurodiversity-affirming language (e.g., replacing “noncompliant” with “communicating unmet need”); (2) Video modeling of PECS exchanges; (3) Sensory diet planning using the STAR Institute’s framework; and (4) Trauma-informed de-escalation specific to motor-planning challenges.

Interdisciplinary meetings occur every 3 weeks—not monthly—to adjust strategies based on data trends. Minutes document decisions verbatim: “Based on ABC data showing 87% reduction in ear-covering during circle time after acoustic panel installation, continue current lighting/sound protocol. Next step: introduce one new PECS icon (‘outside’) during transition to playground.” Roles are explicitly assigned: Lead teacher tracks communication data; OT monitors motor milestones; SLP oversees oral-motor and AAC use; family partner coordinates home carryover.

Community Resource Integration

Local partnerships extend support beyond the classroom. Turan receives physical therapy through Early Childhood Special Education (ECSE) services delivered at his preschool site (Portland Public Schools, Region 1). He also attends weekly group sessions at the Children’s Healing Center—a nonprofit offering sensory integration groups using equipment including a Lite Gait® pediatric treadmill (adjustable speed: 0.1–1.2 mph) and a Snoezelen® multisensory room with fiber-optic curtains and vibro-acoustic flooring (Vibroacoustic Therapy System, model VTS-300).

Financial assistance comes via Oregon’s Preschool Promise program (state-funded tuition support) and Supplemental Security Income (SSI) benefits—$329/month as of April 2024—used for co-pays and home materials. Community health workers from Latino Network connect Aisha with culturally responsive parenting groups and transportation vouchers for medical appointments.

These integrated supports reflect a systems-level approach—not isolated interventions. Turan’s growth is measured not in catch-up milestones but in functional gains: initiating requests with PECS in 65% of opportunities (up from 12%), tolerating 15 minutes of seated circle time with fidget tool (up from 2 minutes), and demonstrating recognition of his name in print (100% accuracy on 5-trial probe). His trajectory underscores that developmental progress is neither linear nor uniform—but deeply responsive to precise, data-informed, relationship-centered practice.

His story reminds us that competence is not defined by conformity to neurotypical timelines. When we calibrate expectations to individual neurology—and align supports to measurable, functional outcomes—we create conditions where children like Turan don’t just participate, but belong, contribute, and communicate with increasing confidence and clarity.

For educators, this means rejecting deficit framing in favor of asset mapping: Turan’s sustained visual attention to moving objects (duration: median 42 sec) supports strength-based science instruction; his rhythmic rocking provides insight into preferred vestibular input that can be channeled into structured movement breaks; his strong preference for predictable routines becomes the scaffold for introducing novel vocabulary.

It also means honoring caregiver expertise. Aisha identified Turan’s first meaningful gesture—a palm-up reach for water at 14 months—months before formal assessment flagged concern. Her observations directly informed the decision to prioritize functional communication over expressive labeling in intervention planning.

Real progress emerges not from accelerating development but from removing barriers to expression, movement, and connection. Turan’s 24-month profile is not a prognosis—it’s a dynamic, evolving map of needs, strengths, and responsive opportunities.

His Bayley-4 scores remain below average, yes—but his rate of growth in functional communication (120% increase in communicative acts/hour over 10 weeks) exceeds national benchmarks for children with similar profiles (mean growth: 78%, CDC Early Intervention Data Report, 2023). That difference is not statistical noise. It’s the direct result of aligned, evidence-based, human-centered practice.

When educators understand the specificity of a child’s sensory thresholds, motor planning capacities, and communication pathways, they stop asking “What’s wrong?” and start asking “What does this behavior tell us about his needs—and how do we meet them precisely?”

Turan’s journey illustrates that inclusion isn’t about fitting a child into a pre-existing structure. It’s about reshaping the environment, adjusting expectations, and expanding our repertoire of connection—until every child’s way of being in the world is not just accommodated, but honored, understood, and actively invited into community.

This work demands humility, precision, and unwavering commitment to seeing the child—not the diagnosis—as the starting point. Turan’s voice, whether spoken, signed, or gestured, is already full of meaning. Our role is not to teach him how to speak, but to learn how he speaks—and respond in kind.

These numbers describe a profile—not a person. They inform support, never define potential. Turan’s laughter during bubble play, his focused gaze while stacking blocks, his reaching hand when a familiar song begins—these moments hold equal weight in shaping who he is and who he will become.

As early childhood professionals, our most vital tool isn’t any assessment or curriculum. It’s our willingness to observe closely, interpret generously, and respond faithfully—to meet Turan where he is, today, with respect, skill, and unwavering belief in his capacity to grow, connect, and communicate in ways that matter.

That belief, consistently embodied in everyday interactions, is the foundation upon which all other supports rest—and the most powerful intervention of all.

His story continues—not as a case study, but as a living, breathing, communicating member of a learning community where his presence reshapes what teaching, learning, and belonging truly mean.

1. Wait 5+ seconds before responding to any vocalization or gesture
2. Match his affect and energy level—not adult expectations of “engagement”
3. Use only one symbol (sign/picture/word) per communication attempt
4. Track vocalizations hourly—not just words, but any intentional sound
5. Observe and record sensory triggers before labeling behavior as “challenging”

These aren’t strategies for Turan alone. They’re practices that deepen responsiveness for every child—because when we learn to listen to the subtlest forms of communication, we become better listeners for all.

Turan doesn’t need to change to fit the world. The world—and our practices within it—must adapt to hold space for his unique way of thinking, moving, feeling, and expressing.

That adaptation is not accommodation. It is justice. It is pedagogy. It is love made visible in structure, routine, and response.

And it begins—not with a diagnosis, not with a score—but with watching Turan closely, noticing what brings him calm or joy or curiosity, and building from there.

Every child deserves that kind of attention. And every educator has the capacity to offer it—when equipped with knowledge, supported by collaboration, and guided by unwavering respect for neurodiversity.

Turan is 24 months old. He is learning. He is communicating. He is growing. And he is, unequivocally, enough—exactly as he is.
