Chapter 14 Development Psychology  the study of how disorders arise and how they change with time. Echolalia  repeating the speech of others.  Is an immediate step in language development.  Not a symptom of autism, just a sign of relatively delayed language skills. Attention Deficit/Hyperactivity Disorder (ADHD) Developmental disorder featuring maladaptive levels of inattention, excessive activity, and impulsiveness. - One of the most common reasons children are referred for mental health services. - Pattern of inattention – not pay attention in school or work related tasks - Hyperactivity – fidgeting, trouble for sitting for a length of time - Impulsivity – acting apparently without thinking – blurting out answers before questions have been completed - Can disrupt academic efforts as well as social relationships - Difficulty sustaining their attention on a task or activity - Either inattention or both hyperactivity and impulsivity must be present for someone to be diagnosed with ADHD. - Occurs in 6% of school children Learning Disorders Reading, mathematics, or written expression performance substantially below levels expected relative to the person's age, IQ, and education. Reading Disorder  a significant discrepancy between a person’s reading achievement and what would be expected for someone the same age. Dyslexia. Mathematics Disorder  achievement below expected performance in mathematics Disorder of Written Expression  achievement below expected performance in writing Stuttering  Disturbance in the fluency and time patterning of speech (e.g., sound and syllable repetitions or prolongations).

Symptoms may include a markedly limited vocabulary or errors in verb tense.

Tic Disorders  Disruption in early development involving involuntary motor movements or vocalizations. Pervasive Developmental Disorders Wide-ranging, significant, and long-lasting dysfunctions that appear before the age of eighteen. - Problems with language, socialization and cognition o Autistic Disorder o Asperger’s Disorder o Rett’s Disorder o Childhood Disintegrative Disorder o Pervasive Developmental Disorder – not otherwise specified Asperger’s Disorder  characterized by impairments in social relationships and restricted or unusual behaviours, but without language delays seen in autism. Rett’s Disorder  Progressive neurological developmental disorder featuring constant hand-wringing, mental retardation, and impaired motor skills. Childhood Disintegrative Disorder  involves severe regression in language, adaptive behaviour, and motor skills after a two-year to four-year period of normal development. Pervasive Developmental Disorder – not otherwise specified  Severe and pervasive impairments in social interactions that do not meet all the diagnostic criteria for autistic disorder. Autistic Disorder Childhood disorder, characterized by significant impairment in social interactions and communication and by restricted patterns of behaviour, interest and activities.
