The Impact of Technology on the Developing Child

Reminiscing about the good old days when we were growing up is a memory trip well worth taking, when trying to understand the issues facing the children of today. A mere 20 years ago, children used to play outside all day, riding bikes, playing sports and building forts. Masters of imaginary games, children of the past created their own form of play that didn't require costly equipment or parental supervision. Children of the past moved... a lot, and their sensory world was nature based and simple. In the past, family time was often spent doing chores, and children had expectations to meet on a daily basis. The dining room table was a central place where families came together to eat and talk about their day, and after dinner became the center for baking, crafts and homework.

Today's families are different. Technology's impact on the 21st century family is fracturing its very foundation, and causing a disintegration of core values that long ago were what held families together. Juggling work, home and community lives, parents now rely heavily on communication, information and transportation technology to make their lives faster and more efficient. Entertainment technology (TV, internet, videogames, iPods) has advanced so rapidly, that families have scarcely noticed the significant impact and changes to their family structure and lifestyles. A 2010 Kaiser Foundation study showed that elementary aged children use on average 8 hours per day of entertainment technology, 75% of these children have TV's in their bedrooms, and 50% of North American homes have the TV on all day. Add emails, cell phones, internet surfing, and chat lines, and we begin to see the pervasive aspects of technology on our home lives and family milieu. Gone is dining room table conversation, replaced by the "big screen" and take out. Children now rely on technology for the majority of their play, grossly limiting challenges to their creativity and imaginations, as well as limiting necessary challenges to their bodies to achieve optimal sensory and motor development. Sedentary bodies bombarded with chaotic sensory stimulation, are resulting in delays in attaining child developmental milestones, with subsequent impact on basic foundation skills for achieving literacy. Hard wired for high speed, today's young are entering school struggling with self regulation and attention skills necessary for learning, eventually becoming significant behavior management problems for teachers in the classroom.

So what is the impact of technology on the developing child? Children's developing sensory and motor systems have biologically not evolved to accommodate this sedentary, yet frenzied and chaotic nature of today's technology. The impact of rapidly advancing technology on the developing child has seen an increase of physical, psychological and behavior disorders that the health and education systems are just beginning to detect, much less understand. Child obesity and diabetes are now national epidemics in both Canada and the US. Diagnoses of ADHD, autism, coordination disorder, sensory processing disorder, anxiety, depression, and sleep disorders can be causally linked to technology overuse, and are increasing at an alarming rate. An urgent closer look at the critical factors for meeting developmental milestones, and the subsequent impact of technology on those factors, would assist parents, teachers and health professionals to better understand the complexities of this issue, and help create effective strategies to reduce technology use. The three critical factors for healthy physical and psychological child development are movement, touch and connection to other humans. Movement, touch and connection are forms of essential sensory input that are integral for the eventual development of a child's motor and attachment systems. When movement, touch and connection are deprived, devastating consequences occur.

Young children require 3-4 hours per day of active rough and tumble play to achieve adequate sensory stimulation to their vestibular, proprioceptive and tactile systems for normal development. The critical period for attachment development is 0-7 months, where the infant-parent bond is best facilitated by close contact with the primary parent, and lots of eye contact. These types of sensory inputs ensure normal development of posture, bilateral coordination, optimal arousal states and self regulation necessary for achieving foundation skills for eventual school entry. Infants with low tone, toddlers failing to reach motor milestones, and children who are unable to pay attention or achieve basic foundation skills for literacy, are frequent visitors to pediatric physiotherapy and occupational therapy clinics. The use of safety restraint devices such as infant bucket seats and toddler carrying packs and strollers, have further limited movement, touch and connection, as have TV and videogame overuse. Many of today's parents perceive outdoor play is 'unsafe', further limiting essential developmental components usually attained in outdoor rough and tumble play. Dr. Ashley Montagu, who has extensively studied the developing tactile sensory system, reports that when infants are deprived of human connection and touch, they fail to thrive and many eventually die. Dr. Montagu states that touch deprived infants develop into toddlers who exhibit excessive agitation and anxiety, and may become depressed by early childhood.

As children are connecting more and more to technology, society is seeing a disconnect from themselves, others and nature. As little children develop and form their identities, they often are incapable of discerning whether they are the "killing machine" seen on TV and in videogames, or just a shy and lonely little kid in need of a friend. TV and videogame addiction is causing an irreversible worldwide epidemic of mental and physical health disorders, yet we all find excuses to continue. Where 100 years ago we needed to move to survive, we are now under the assumption we need technology to survive. The catch is that technology is killing what we love the most...connection with other human beings. The critical period for attachment formation is 0 - 7 months of age. Attachment or connection is the formation of a primary bond between the developing infant and parent, and is integral to that developing child's sense of security and safety. Healthy attachment formation results in a happy and calm child. Disruption or neglect of primary attachment results in an anxious and agitated child. Family over use of technology is gravely affecting not only early attachment formation, but also impacting negatively on child psychological and behavioral health.

Further analysis of the impact of technology on the developing child indicates that while the vestibular, proprioceptive, tactile and attachment systems are under stimulated, the visual and auditory sensory systems are in "overload". This sensory imbalance creates huge problems in overall neurological development, as the brain's anatomy, chemistry and pathways become permanently altered and impaired. Young children who are exposed to violence through TV and videogames are in a high state of adrenalin and stress, as the body does not know that what they are watching is not real. Children who overuse technology report persistent body sensations of overall "shaking", increased breathing and heart rate, and a general state of "unease". This can best be described as a persistent hypervigalent sensory system, still "on alert" for the oncoming assault from videogame characters. While the long term effects of this chronic state of stress in the developing child are unknown, we do know that chronic stress in adults results in a weakened immune system and a variety of serious diseases and disorders. Prolonged visual fixation on a fixed distance, two dimensional screen grossly limits ocular development necessary for eventual printing and reading. Consider the difference between visual location on a variety of different shaped and sized objects in the near and far distance (such as practiced in outdoor play), as opposed to looking at a fixed distance glowing screen. This rapid intensity, frequency and duration of visual and auditory stimulation results in a "hard wiring" of the child's sensory system for high speed, with subsequent devastating effects on a child's ability to imagine, attend and focus on academic tasks. Dr. Dimitri Christakis found that each hour of TV watched daily between the ages of 0 and 7 years equated to a 10% increase in attention problems by age seven years.

In 2001 the American Academy of Pediatrics issued a policy statement recommending that children less than two years of age should not use any technology, yet toddlers 0 to 2 years of age average 2.2 hours of TV per day. The Academy further recommended that children older than two should restrict usage to one hour per day if they have any physical, psychological or behavioral problems, and two hours per day maximum if they don't, yet parents of elementary children are allowing 8 hours per day. France has gone so far as to eliminate all "baby TV" due to the detrimental effects on child development. How can parents continue to live in a world where they know what is bad for their children, yet do nothing to help them? It appears that today's families have been pulled into the "Virtual Reality Dream", where everyone believes that life is something that requires an escape. The immediate gratification received from ongoing use of TV, videogame and internet technology, has replaced the desire for human connection.

It's important to come together as parents, teachers and therapists to help society "wake up" and see the devastating effects technology is having not only on our child's physical, psychological and behavioral health, but also on their ability to learn and sustain personal and family relationships. While technology is a train that will continually move forward, knowledge regarding its detrimental effects, and action taken toward balancing the use of technology with exercise and family time, will work toward sustaining our children, as well as saving our world. While no one can argue the benefits of advanced technology in today's world, connection to these devices may have resulted in a disconnection from what society should value most, children. Rather than hugging, playing, rough housing, and conversing with children, parents are increasingly resorting to providing their children with more videogames, TV's in the car, and the latest iPods and cell phone devices, creating a deep and widening chasm between parent and child.

Attention Deficit Disorder (ADD/ADHD) and Avoiding the Problem of Medicating a Developing Brain

Attention Deficit Disorder (ADD) appeared first in the 1980 Diagnostic and Statistical Manual of the American Psychological Association. Today ADD means different things to different professionals, depending upon their field, their level of experience and medical knowledge, and their cultural beliefs about how children should act.

Parents are often surprised to learn that there is no particular medical or neurological abnormality present in individuals diagnosed with attention deficit. Instead, the diagnosis depends upon subjective assessments by parents, teachers, or professionals with little or no understanding of the neuroscience of learning and behavior.

In fact, the National Institutes of Health (NIH) issued a consensus statement in 1999 warning that the causes and treatments of ADD are only speculative. In a very real sense, the diagnosis itself is only speculative.

In spite of this, individuals and even very young children who are given a diagnosis of ADD are typically given a prescription for an amphetamine, usually methylphenidate. This amphetamine is very similar to cocaine in terms of its effects on the brain (see Volkow et al, 1995); both drugs compete for the same binding sites on brain cells, both are taken up into the same areas of the brain, and both produce similar psychological effects. Perhaps the major differences are that methylphenidate remains in the brain much longer and the psychological expectations associated with the drug are much different.

Both methylphenidate and cocaine affect the brain by increasing levels of dopamine in the frontal lobes, an area responsible for motor planning, learning, problem solving, impulse control, memory, attention, language, analytical thinking and social behavior, and the striatum, an area responsible for processing and integrating sensory information.

Increased levels of dopamine make the brain feel powerful and happy and can produce addictive behaviors and responses. Elevated levels of dopamine also alter other neurochemicals and affect control muscle movements, sleep/wake cycles, hunger and satiety, arousal, heart rate, blood pressure, and stress responses.

If these altered levels of neurochemicals persist for too long (e.g. several weeks), the brain begins to try to bring the levels back to normal. If a neurochemical has been elevated for too long, the brain will begin to shut down some of the receptors for that neurochemical and will begin to kill off some of the transporters that move the neurochemical through the brain. We call this effect "downregulation."

After about three weeks it is possible to see these architectural changes with the electron microscope; after about four months the changes are significant. Four months on methlyphenidate, for example, will result in the loss of about 75% of the dopamine transporters and 20% of the dopamine receptors in the striatum (Vles et al, 2003). The striatum is an area of the brain critical for sensory processing, learning and memory.

Downregulation can have significant effects on the developing brain long after the drug has been withdrawn. Early exposure to methylphenidate, for example, has been linked to decreased interest in sex, food, emotional experiences, and novelty, and an increase in anxiety and stress levels in adolescence and adulthood (Bolanos, et al, 2003).

Of course, the brain can also "upregulate" by growing more transporters or receptors or making the remaining receptorsor more sensitive. However, upregulatio takes time.

It is dangerous to abruptly stop taking a medication after downregulation has occurred, so following a weaning schedule is recommended. The speed at which an individual is weaned from a drug like methylpheidate is based on the length of time they have been taking the medication and the dosage that they were receiving. A physician familiar with the neurological properties of the drug should be consulted before attempting to wean someone off such a drug.

Regardless of the problems associated with medications used to "treat" attention deficit, the question remains as to why a child is having problems paying attention. There are a host of metabolic, immunological, neurolgoical sensory and psychological causes of inattention including: metabolic disorders, allergies, toxins, sleep disorders, vitamin or fatty-acid deficiencies, thyroid disorders, diabetes, depression, boredom intolerance, high intelligence, high creativity, frontal lobe dysfunction, auditory or vestibular processing disorders, and learning disabilities.

Correctly identifying the underlying cause of inattention can help parents and medical professionals avoid the problems of exposing a developing brain to medications that alter neurochemicals, produce downregulation or create long-term side effects that may be far more serious than inattention.
