In this chapter, we will highlight findings from behavioral research examining deficits in three areas of social cognition in individuals with autism, including imitation, empathy, and theory of mind, review the research on implicating mirror neurons in autism spectrum disorders and explore the mirror neuron theory of autism.

The interaction between empathy and the autism spectrum is a complex and ongoing field of research, and several different factors are proposed to be involved, including alexithymia, impaired theory of mind, and reduced mirror neuron activity. A mirror neuron is a neuron that fires both when an animal acts and when the animal observes the same action performed by another thus, the neuron mirrors the behavior of the other, as though the observer were itself acting.
Noninvasive interventions using rhythm, such as dance and singing, present great potential in the treatment of autism because rhythm inherently entrains movement through the stimulatory effect on residual mirror neuron function, and children are most receptive to these cues [47, 55. Mirror neurons and autism a mirror neuron is a neuron which fires both when an animal performs an action and when the animal observes the same action performed by another (especially conspecific) animal. But while many in the field follow that logic for autism's social impairments, there is less agreement on whether the disorder's mental retardation and repetitive behaviors could arise from a mirror-neuron system gone awry.
The broken mirror hypothesis claims that individuals with asd have impairments to their mirror neuron system (press, richardson & bird, 2010) and further suggest that the dysfunction of the mirror neuron system is a primary cause of the poor social skills in individuals with autism (marsh & hamilton, 2011. The mirror neuron system itself could be normal [in autism], but its projections, or the brain regions it is projecting to, could be abnormal instead, ramachandran says he adds that the mixed results could be due to the heterogeneity of the autism spectrum disorders. In the first study of the mirror neuron system in children with asd compared with age- and iq-matched typical children, the children with autism showed no mirror neuron activation in the pars opercularis during either observation or imitation of emotional face expressions. Research findings support the idea of impaired mirror neuron functioning in asd in adults (eg, bernier et al, 2007) and children for example in the study of oberman and.

Autism spectrum disorders (asd) are largely characterized by deficits in imitation, pragmatic language, theory of mind, and empathy previous research has suggested that a dysfunctional mirror neuron system may explain the pathology observed in asd. Abstract this paper reviews the present theories and empirical research of autisms' cognitive research and mirror systems and introduces a new hypothesis about the causes of autism spectrum disorders (asd): autistic mirror neuron dysfunction hypothesis. Autism spectrum disorder (asd) is a highly prevalent neurodevelopmental disorder characterized by impaired social communication and restricted and repetitive behaviors (rrbs) over the past decade, neuroimaging studies have provided considerable insights underlying neurobiological mechanisms of asd. Eeg evidence for mirror neuron dysfunction in autism spectrum neural mechanisms of imitation and 'mirror neuron' functioning in autistic spectrum disorder.
An association between autistic spectrum disorder and imitative impairment might result from dysfunction in mirror neurons (mns) that serve to relate observed actions to motor codings. Neurofeedback training elicits behavioral improvements in individuals with asd february 27, 2008 scientists have recently proposed that problems in the brain's mirror neuron system during early development could be responsible for many of the impairments seen in autism spectrum disorder (asd. Mirror neurons and autismthese ideas lead directly to our hypothesis that some dysfunction in the mn system might be implicated in the generation of the constellation of clinical features which constitute the autistic syndrome the most basic hypothesis would be that there is a failure or distortion in the development of the mirror neuron system. The neural substrate of imitation in people affected by autistic spectrum disorder (asd) is therefore of much interest there is a need to ascertain whether individuals with asd utilise the mn system less or in a different way during imitation, or whether other neural structures required for imitation are affected. We review literature pertaining to the mirror neuron system and develop a theory of disordered mirror neuron functioning in dcd finally, we review the limited neuroimaging literature available on neural correlates of dcd and show that the findings from those investigations are congruent with a mirror neuron system theory of dcd.
Early predictors of communication development in young children with autism spectrum disorder: joint attention, imitation, and toy play journal of autism and developmental disorders , 36(8), pp993-1005. The mirror neuron system allows a person to understand the actions, intentions, and emotions of another person and is thought to participate in such higher cognitive processes as language, imitation, and empathy.
Motor and gestural skills of children with autism spectrum disorders (asd), developmental coordination disorder (dcd), and/or attention deficit hyperactivity disorder (adhd) were investigated. Neural mechanisms of imitation and 'mirror neuron' functioning in autistic spectrum disorder february 2006 neuropsychologia an association between autistic spectrum disorder and imitative impairment might result from dysfunction in mirror neurons (mns) that serve to relate observed actions to motor codings.
Because autism is characterized, in part, by deficits in exactly these sorts of social interaction and communication skills, previous research has suggested that a dysfunctional mirror neuron.
