Comprehensive Developmental based approaches such as DIR/Floortime are strongly grounded in infant and early childhood mental health, clinical and developmental psychology and the neurosciences. They are peer reviewed evidenced based Developmental neuroscientific approaches to treat children and older with autism spectrum disorder and other biopsychosocial based challenges. Below are several resources that validate a comprehensive DIR/Floortime developmental based approach to treat children with ASD and other biopsychosocial based challenges and the neuroscientific foundations that justify its use as a primary intervention approach with children and families.
In 2011 preliminary results from a fully randomized control trial of 51 children with mild to severe autism, ages 2 years 0 months to 4 years 11 months, were published by the MEHRI Foundation at York University, Canada. Participants were assigned to either a target treatment group (DIR Floortime, 25 children) or community treatment group (26 children, 16 received ABA). The study evaluated a social-communication based approach to autism. PET scans of all children were taken prior to trial start and post trial to record any neuronal changes. What was quite remarkably demonstrated were clinically significant and clinically meaningful structural neuronal changes in formerly underactive and overactive areas of brain functioning demonstrated among participants in the targeted treatment vs. control group.
Data sets among participants in the targeted DIR/Floortime treatment group (one child here presented in video below) revealed significant increased activity in the prefrontal cortex area (e.g., executive functioning responsible for emotional regulation, ideation, motor planning and sequencing); significantly reduced adverse subcortical functioning (e.g., reduced size and activity of the amygdala and over activation of the hypothalamus, pituitary and adrenal axis responsible for All or Nothing responses); increased positive functioning in FFA (fusiform face area of the fusiform gyrus) responsible for scanning, reading and processing the emotional-facial expressions of others. Overall neuronal activity was found to be more consistent with what typically observe in healthy developing children. These prefrontal and subcortical changes were directly correlated with specific milestone increases in simple to complex circles of increasingly continuous and reciprocal social-emotional child/parent interactions and were demonstrated in the targeted treatment group vs. the community group. Re-analysis of trial result data in 2015 further revealed that the targeted treatment group considerably outperformed the community group on number of utterances produced and various speech act categories.
The published preliminary and follow up data on the 2011 MEHRI Foundation study (cited above) as well as separately other previous and current controlled randomized trials supporting a comprehensive developmental based approach, such as DIR/Floortime as a primary treatment methodology for young children and older diagnosed with ASD can be found at http://www.icdl.com/research
The following is a one hour and forty minute talk with video presentation given by one the most experienced, internationally renown DIR/Floortime Occupational therapist,, Rosemary White., OTR/L. This talk and video presentation is extraordinary useful for both families and clinicians as Rosemary explains in a remarkably detailed and nuanced perspective the theory of DIR/Floortime methodology in everyday practice.
The following white paper by Diane Cullinane, M.D. is an overview of the scientific evidentiary support for the DIR/Floortime methodology to treat infants, toddlers and older with ASD and related affect-sensory and social pragmatic communication based challenges:

Below are the Clinical Practice Guidelines of the Interdisciplinary Council Developmental Learning (ICDL) published in 2001. It is a comprehensive overarching view of the biopsychosocial components that form the neuroscientific foundations for a comprehensive Developmental assessment and treatment approach for individuals diagnosed with autism spectrum and other biopsychosocial challenges. The chief editor is the late Dr. Stanley Greenspan, M.D. (former head of NIMH, Mental Health Study Center and the Clinical Infant Development; co-founder of Interdisciplinary Council Developmental Learning and the DIR/Floortime methodology). It is co-authored by many of the foremost professionals within the biopsychosocial sciences.
Now, it is extremely valuable for all primary caregivers and clinicians working with infants, toddlers, older children and adults with ASD to begin to read the voluminous evidenced-based research that supports not the older traditional and essentially simplistic surface behavioral based models (ABA) but rather comprehensive evidenced-based Developmental social pragmatic approaches (DSP) such as DIR/ Floortime. The latter address not selectively targeted or circumscribed behaviors but rather the primary core Functional Emotional Developmental challenges associated with ASD. Unlike traditional applied behavioral based models, DSP approaches neither render nor conflate a false evidentiary equivalence between the biopsychosocial complexity of each child's core Functional-Emotional Developmental capacities and individual sensory-affect-motor processing differences with each child “successfully redirected” to execute selectively targeted behavioral/academic performance tasks on cue (e.g., the ability for each child to produce on adult command from declarative memory a set of functionally-scripted responses or what colleagues and I refer to as "surface trained behaviors”). Despite decades of extraordinarily rewarding behavioral and-pharmaceutical lobbying/marketing campaigns and resulting public perception in concluding on the necessity to suppress symptoms and shape or redirect their child’s “problem behaviors”, what is significantly overlooked are the core primary emotional-developmental relationship based challenges in typical and non-typical infant, toddler and older development.
Developmental social pragmatic approaches such as DIR/Floortime focus on the core biopsychosocial underlying foundations that constitute healthy relating, engaging and communicating in the context of child/primary caregiver and peer-relationships. What has been clearly demonstrated over the last twenty-five years of research in Developmental Affect Neuroscience and early infant, toddler mental health in anatomical studies and neuroimaging beginning in utero between two brains (the mother’s right orbital frontal cortex and limbic, hypothalamus, pituitary and adrenal axis to the prenatal, infant and toddler’s right hemisphere) is how the synaptic growth and maturation of the child’s limbic system (i.e., limbic, hypothalamus, pituitary adrenal axis) with the inchoate emerging prefrontal connect is critically dependent from infancy upon secure, consistent and healthy dyadic child/parent emotional interactions. Beginning postnatally, this includes the Developmental biopsychosocial processes of infant/toddler/primary caregiver reciprocal emotional deepening attachment and attunement and simple to complex social-emotional reciprocal interactions (e.g., co-engaging, co-thinking and co-communicating).
Therefore, evidenced based Developmental social pragmatic treatment approaches such as DIR/Floortime for-typical as well as non-typical developing children are entirely centered around the integration of the child's subcortical with cortical functioning (e.g., child's emerging "sense of self with others" guided by the child's affective individual sensory processing differences and addressed in the context of child/primary caregiver relationships). In non-typical development, such as ASD, it is not the isolation or an inventory checklist of the child's circumscribed or “problem behaviors” targeted for modification but rather guiding primary caregivers to use their natural emotional intelligence to learn how to slow down and emotionally connect and engage with their child's constitutional developmental and sensory-affect-motor processing challenges that significantly enables the strengthening of these underlying neuronal pathways that lead toward the formation of new synaptic connections and meaningful Developmental milestone advance.
The justification for an evidenced based developmental social-emotional based approach garnered new appreciation by the tremendous advances made in the fields of neuroendocrinology and neuroanatomy during the mid 1990's. At this point in time there was conceptualized a radically new understanding of a non-bifurcated autonomic nervous system that is socially-emotionally co-regulated and hierarchically structured-for purposes of homeostasis or under conditions of threat recruited to fight, flight, freeze or feint responses by three distinct nervous system circuits of the unmyelineated and myelineated vagus nerve (i.e., sub-diaphragmatic and diaphragmatic and supra-diaphragmatic). The more advanced myelineated vagus nerve pathway beginning with mammals is directly connected in the basal ganglia to the striated facial muscles, ocular muscles, auditory system/middle ear and the pharyngeal and laryngeal muscles required for speech and represents a new understanding of the biopsychosocial foundations that constitute early mammal to human primate social-emotional engagement-and-autonomic regulation.
A new understanding of this phylogenetically distinct myelinated vagal pathway in humans had provided for the first time a biopsychosocial understanding of the pivotal evolutionary role that the social-emotional engagement system (i.e., the higher myelinated aspects of the mammalian vagus nerve) directly has in down regulating sympathetic flight, fight, freeze or feint responses and the subsequent reduction of an excess of stress hormones, such as testosterone, vasopressiin and cortisol or conversely a positive increase in hormones, such as dopamine, serotonin and oxytocin, the latter regulated by the earlier mammalian limbic hypothalamus, pituitary adrenal axis.
For example, pleasurable back and forth co-regulated/regulated parent with child face to face engagement; auditory-prosodic, tactile-gestural secure based attachment and attunement results in critical homeostasis (e.g., auditory attunement, mobilization for play/up-regulation of joy as well as parasympathetic calm and restoration) or conversely, fight/ flight freeze or feint responses due to early trauma ( e.g., insecure and avoidant attachment or abuse and neglect). Now, separately, in non-typical development beginning in utero, for example, immune or endocrine system compromises due to the mother’s exposure during pregnancy to neurotoxins can result in heterogeneous functional emotional developmental disorders such as autism spectrum or related developmental disorders. In the latter we can often clearly identify or point to a separate set of biological-genetic constitutional components resulting in neurophysiological traumatic stress. Nonetheless, what is notable is that in both typical and non-typical development we often see very similar biopsychosocial etiologies with respect to vagus nerve auditory attunement or auditory shut down; functional-emotional expressive use of facial, bodily gestural reciprocity and the ability to optimally regulate the laryngeal and pharyngeal muscles required for vocalization, that is, the emotional or prosodic elements of speech which comprise 93% of spoken language.
A new understanding of the evolutionary significance of this myelinated vagal branch (e.g., striated facial, middle ear, ocular, vocalization) represented a huge paradigm shift towards a much more expansive and nuanced understanding of how social-emotional engagement came to serve a new and hierarchical transformational role in regulating autonomic functioning, beginning with the evolution of the shut down or immobilzation response in the reptilian brain to the fight/flight response in the mammalian brain and how each of these features are hierarchically structured (primitive, limbic, neocortex) in our own phylogeny and either optimally regulated (e.g., calm, well-regulated deepening back and-forth social-emotional engagement, including complex ideation and expressive language - that is core human executive functioning) or circumvented and recruited to primitive or regressive functioning (e.g., fight, flight or an immobilization response) by these two contiguous but evolutionary distinct vagal pathways (see, Porges, S. 1995.

Neurotypical Development, the maturation of the brain: Birth to Three.
The neuroscientific evidence over the last several decades clearly demonstrates a direct correlation between forming healthy neuronal [brain] patterns of connectivity and child/primary caregiver nurturance based practices: The nature of child/caregiver deepening affect reciprocal attachment and complex two-way reciprocal emotional problem solving (e.g., back and forth co-referencing with visual-facial, auditory prosodic and tactile gestural exchanges) with respect to building the emotional foundations of the child's healthy core "sense of self" and correspondingly the child's intact, integrated and healthy emerging developmental milestones (i.e., social-emotional relating, thinking and nonverbal to verbal communicating) have been well established in the fields of infant mental health, epigenetic research on deepening reciprocal attachment and affect regulation on right to left brain development beginning in utero and early childhood, clinical and developmental, psychotherapy and psychoanalysis.
For example, since the 1990's this has been corroborated by extensive neuroscientific research that clearly demonstrates that the healthy integration of each infant's sensory and motor connections and how these inchoate connections, incipient neuronal pathways from birth, turn on genes, produce proteins and form into complex synaptic patterns (the maturation of the wiring of the neuronal pathways) including the maintenance of healthy vagal tone (e.g., autonomic regulation and heart rate variability) are directly dependent upon highly emotionally attuned and responsive primary caregiver interactions. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4318551/
For the seminal ground breaking work that began to transform the former disparate fields of neuroanatomy, neurobiology, early infant child mental health, psychoanalysis, family law and Developmental psychology into a new understanding and synthesis, an over-arching theoretical framework and a new foundation for Affect Developmental evidenced based treatment practice see, Schore, Allan, 1994, Affect Regulation and the Origin of Self: The Neurobiology of Emotional Development.

The understanding of this fundamental and highly nuanced child/primary caregiver dyadic, triadic and multi-social framework (indeed, if we look at the extended family system) can be correctly conceived of in terms of a significant paradigm shift or the bridging of the fields of Developmental psychology and neurobiology with respect to a new and comprehensive understanding of the formerly viewed disparate biological, psychological-and-social components. This critically encompasses the relational (epigenetic factors) of early infant/toddler/primary caregiver secure or insecure attachment practices that significantly determines the trajectory of what and how genes turn on and off, produce proteins and form and maintain healthy or unhealthy neuronal connectivity (what internationally renown attachment researcher and psychiatrist, Dr. Dan Siegal has termed, “Interpersonal Neurobiology”).
Justifiably, this is now conceptualized as the underlying foundation of developmental social pragmatic evidenced based treatment practices such as DIR/Floortime with respect to understanding and guiding primary caregivers in facilitating and maintaining early infant and childhood mental health as well as treating children with autism spectrum challenges. The latter is a fundamental move away from the past traditional cognitive dissonance of brain treated apart from body (e.g., in traditional practice treating cognitive, language, motor functions as separate components) or in applied behavioral analysis “targeting selective behaviors” toward a social-emotional mind-brain-body integrated approach in accordance to the last twenty-five years of research in Developmental Affect Neuroscience. Due to the advances in technology over the last twenty-five years we can now more accurately measure our data (adult-child inter-brain communication and how the synapses epigenetically begin to form in real-time (i.e., PET, fMRI ). We can demonstrate direct correlation between neuronal growth (e.g., synaptic formation and interconnectivity across different parts of the brain) during healthy child/caregiver nurturance or conversely impaired neuronal activity due to unhealthy nurturance practices. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3968319/ http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0181066
I have provided at the end of this section several additional links to some audio and video discussions for families and clinicians working in the field on what actually constitutes the healthy affective basis of childhood development (i,e., the roots of emotional intelligence). Now, given a child's healthy underlying biological and immune system, the perennial question prior to 1990's was, "What is it that brings the early developing parts of the infant's brain (primitive reflexes, senses and emotions: heart rate variability, breathing, blinking, sensations to sense of touch warmth; auditory, soothing or alarming voice, vision, etc.) into organized and meaningful affective patterns of simple reciprocal co-regulated engagement (optimal arousal for attending, relating and engaging)?" The answer given by Developmental affect neuroscience is the co-regulated partner(s) or "adult higher brain(s)" (the primary caregivers) with the prenatal and postnatal newly forming brain of the child. This is the foundational social-emotional symbiotic relationship absolutely critical for all infant/toddler social-emotional-cognitive development.
Again, what is required to bring the emerging "social brain" of the infant/toddler online with respect to basic executive functioning from simple to increasingly complex engagement with others (e.g., regulated/co-regulated sensory-affect-motor ideation, sequencing and engagement) is the more experienced or higher brain of the primary caregiver or more specifically the child/primary caregiver dyad, Every human infant is born with approx. 84 billion neurons. The human infant is born biologically equipped with a set of basic reflexes. senses and primitive emotional responses. However, the vast majority of neurons that will form into synapses hooking up these complex neuronal pathways (sensory-affect-motor) are highly malleable and thus only loosely connected at birth and only begin to increasingly coalesce into complex neural networks beginning in the last trimester through the first few years of life.
The brain is experience-user/interdependent. The strength of the connectivity and resiliency of the brain's foundations (primitive, limbic and neocortex) are directly co-determined or co-regulated by the "higher brain" of the parent or the child/primary caregiver dyad. This necessitates for optimal integration and resiliency secure based attachment, attunement and reciprocal back and forth emotional social engagement (e.g., beginning from birth with the simplest wooing/pleasurable back and forth emotional signaling between parent and child, connecting, breaking and re-connecting child/parent affect facial expressions, games as simple as "peek-a-boo", etc), all of which help co-structure for the child internally well-regulated biopsychosocial patterns with respect to his/her sympathetic and parasympathetic regulation and increased executive functioning. Again, this must begin with healthy child/parent dyad of secure based attachment and deepening expanded attunement by up-regulating joyful states through play and down-regulating stressful states through soothing. The latter creates the interpersonal neurobiological foundations for increased optimally regulated and resilient complex emotional signaling (e.g., co-emotional gestures, primitive co-prosodic vocalizations, sensory integration, simple to expanded ideation and social-pragmatic expressive language)..
The following absolutely brilliant presentation addresses the emotional basis of attachment, affect regulation and cognition, which biopsychosocially exponentially forms during the last trimester into the end of the second to third year of life and which constitutes the unfolding nature and degree of empathy and resiliency of the primary Functional-Emotional Developmental milestones beginning in infancy throughout the lifespan.

Autism Spectrum And Other Biological-Psychological-Social Developmental Challenges.
What has been far too long ignored in practice by special educators and other clinicians working with children with autism spectrum and other related challenges and too often if at all conveyed to parents (e.g., at the start of early intervention) is the neuroscientific evidence that it is precisely these same principles of healthy nurturance based practices - necessary and indeed critical for each child's core functional emotional developmental milestones (i.e., calm, attentiveness, co-regulated patterns of back and forth emotional regulation, playfulness, ideation) when applied in a therapeutic context (i.e., adjusted or tailored to each child's biological based functional emotional developmental and processing challenges) that does in fact significantly help re-construct new healthy integrated neuronal pathways in the brain.
Guided pleasurable and affectively engaging relationships not just with infants and toddlers but with older children with mild to more involved autism spectrum challenges (due to the brain's enormous neuroplasticity) can not only help facilitate but again as the neuroscientific evidence clearly demonstrates actually re-wire the brain, that is build, strengthen and expand those healthy neural pathways (e.g., improved connectivity between the prefrontal cortex and subcortical functioning and overall integrated sensory-affect-motor functioning - where simple to complex social-emotional affective engagement and pragmatic language development, beginning from the emotional right subcortical to linguistic left prefrontal cortex can begin to re-build and strengthen synaptic connections). An expanding database of evidence over the last decade on neuroplasticity is increasingly demonstrating the ability for individuals to re-construct new neuronal connections throughout the lifespan.
