Some of the traits associated with HFA that will be addressed in the ebook include: (1) emotional problems and sensory sensitivities; (2) difficulties with school-related skills; (3) issues related to health and movement; (4) social skills deficits; (5) behavioral problems; and (6) deficits in linguistic and language development. 
Let's look at each of these in turn:
1. Why do children with HFA experience unique emotional problems and sensory sensitivities? For example:
Let's look at each of these in turn:
1. Why do children with HFA experience unique emotional problems and sensory sensitivities? For example:
- An emotional incident can determine the mood for the day.
 - They can become overwhelmed with too much verbal direction.
 - They often experience difficulty with loud or sudden sounds.
 - Emotions can pass very suddenly -- or are drawn out for a long period of time.
 - They have an intolerance to certain food textures, food colors, or the way food is presented on the plate (e.g., one food can’t touch another).
 - They may laugh, cry, or throw a tantrum for no apparent reason.
 - They may need to be left alone to release tension and frustration.
 - They usually resist change in their environment (e.g., people, places, objects).
 - They experience sensitivity - or lack of sensitivity - to sounds, textures, tastes, smells or light.
 - They tend to either tune out - or break down - when being reprimanded.
 - They have an unusually high - or low - pain tolerance.
 
2. What are the difficulties associated with school-related skills that need to be addressed? For example:
- Difficulty transitioning from one activity to another
 - Difficulty with fine motor activities (e.g., coloring, printing, using scissors, gluing)
 - Difficulty with reading comprehension (e.g., can quote an answer, but unable to predict, summarize or find symbolism)
 - Excellent rote memory in some areas
 - Exceptionally high skills in some areas -- and very low in others
 - Resistance - or inability - to follow directions
 - Short attention span for most lessons
 
3. How should issues related to health and movement be dealt with? For example:
- Allergies and food sensitivities
 - Apparent lack of concern for personal hygiene (e.g., hair, teeth, body odor)
 - Appearance of hearing problems, but hearing has been checked and is fine
 - Constipation
 - Difficulty changing from one floor surface to another (e.g., carpet to wood, sidewalk to grass)
 - Difficulty moving through a space (e.g., bumps into objects or people)
 - Frequent gas, burping or throwing up
 - Incontinence of bowel and/or bladder
 - Irregular sleep patterns
 - Odd or unnatural posture (e.g., rigid or floppy)
 - Seizure activity
 - Unusual gait
 - Walks on toes
 - Walks without swinging arms freely
 
4. Why do these children lack social skills, and what can parents and teachers do to help? For example:
- Aversion to answering questions about themselves
 - Difficulty maintaining friendships
 - Difficulty reading facial expressions and body language
 - Difficulty understanding group interactions
 - Difficulty understanding jokes, figures of speech or sarcasm
 - Difficulty understanding the rules of conversation
 - Does not generally share observations or experiences with others
 - Finds it easier to socialize with people that are older or younger, rather than peers of their own age

 - Minimal acknowledgement of others
 - Overly trusting or unable to read the motives behinds peoples’ actions
 - Prefers to be alone, aloof or overly-friendly

 - Responds to social interactions, but does not initiate them
 - Seems unable to understand another’s feelings
 - Talks excessively about one or two topics (e.g., dinosaurs, movies, etc.)
 - Tends to get too close when speaking to someone (i.e., lack of personal space)
 - Unaware of/disinterested in what is going on around them
 - Very little or no eye contact
 
5. How can behavioral problems be managed effectively? For example:
- Causes injury to self (e.g., biting, banging head)
 - Difficulty attending to some tasks
 - Difficulty sensing time (e.g., knowing how long 5 minutes is or 3 days or a month)
 - Difficulty transferring skills from one area to another
 - Difficulty waiting for their turn (e.g., standing in line)
 - Extreme fear for no apparent reason
 - Feels the need to fix or rearrange things
 - Fine motor skills are developmentally behind peers (e.g., hand writing, tying shoes, using scissors, etc.)
 - Frustration is expressed in unusual ways
 - Gross motor skills are developmentally behind peers (e.g., riding a bike, skating, running)
 - Inability to perceive potentially dangerous situations
 - Meltdowns
 - Obsessions with objects, ideas or desires
 - Perfectionism in certain areas
 - Play is often repetitive
 - Quotes movies or video games
 - Ritualistic or compulsive behavior patterns (e.g., sniffing, licking, watching objects fall, flapping arms, spinning, rocking, humming, tapping, sucking, rubbing clothes)

 - Unusual attachment to objects
 - Verbal outbursts
 
6. What can be done to help with deficits in linguistic and language development? For example:
- Abnormal use of pitch, intonation, rhythm or stress while speaking
 - Difficulty understanding directional terms (e.g., front, back, before, after)
 - Difficulty whispering
 - Makes verbal sounds while listening (i.e., echolalia)
 - May have a very high vocabulary
 - Often uses short, incomplete sentences
