Introduction
Executive functions are higher order functions on the top
level in the cognitive hierarchy, which implies the presence of
basic intellectual functions in respect to which they are
superior. Executive functions thus play the role of controller
and modulator of cognitive functions. It is believed that the
position of executive functions, i.e. the frontal lobe,
(Freeman, 2000) is responsible for the overall ability of
representation of the outer world and executive functions are
responsible for acquisition of all knowledge (Ranganath et
al., 2003). The associative areas of the frontal lobe, strongly
connected with multiple cortical and subcortical structures,
subtend the highest executive functions (Stuss & Alexander,
2007). These appear to be crucial both for the overall
repertoire of finalized behaviors and for the cognitive
productivity, especially for tasks requiring higher attention,
memory and problem solving (MacPherson et al., 2017).
Moreover, these are crucial functions in the regulation of
cognitive processes of "lower level" as well as in the
modulation of the finalized behavior and in the processes of
adaptation to the environment (Alvarez & Emory, 2006).
Executive functions
Executive functions perform complex skills known as
planning, behavior modulating and monitoring, behavioral
and cognitive flexibility and the functions that allow to
voluntarily responding adaptively to complex or non-habitual
conditions in which the automated response schemes are not
appropriate or sufficient to achieve the goal. Research also
revealed that when the task is familiar or simple, "automatic"
action schemes may be sufficient and when the task requires
choices, complex analyses, "automatic responses" are not
sufficient but more "controlled" behavior requiring higher
"attention" become necessary (Jurado & Rosselli, 2007). The
executive functions are fundamental cognitive skills for
achieving good performance in life, as well as in the school
and social environment, allowing people to face new and
complex situations (Lezak, 2004). At the age of 5 years the
three key components of executive functions have already
been partially developed, these being working memory,
inhibition, and cognitive flexibility (Matthew et al., 2006).
Working memory involves the monitoring, manipulation, and
updating of information; while inhibition refers to the ability
to deliberately and precisely inhibit the production of
automatic responses when the situation requires it; while
cognitive flexibility allows for switching effectively between
different mental operations (Miyake et al., 2000, Sastre-
Rivas, 2009). As one component of executive functions,
inhibition can be understood as a set of functions related to
the control of attention and suppression of reflexes or
undesirable behaviors (Diamond, 2013) involving response
inhibition and interference control (Friedman & Miyake,
2004). Friedman and Miyake (2004) also found that the two
types of interference control differentially predicted
performance on executive function tasks thought to rely on
inhibition, offering further support of the distinction between
resistance to proactive and distractor interference. An early
empirical investigation revealed a complex pattern of both
intact and impaired mnemonic abilities (Boucher &
Warrington, 1976; Hermelin & O’Connor, 1967). A research
attempted to make a distinction between learning and
intelligence by including both a group with learning difficulty
and normal IQ and a group with learning difficulty and low
IQ. In results, there were no differences found between the
two groups on executive function measures, but both

ABSTRACT
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by
persistent difficulties in social communication and interaction and restrictive, repetitive,
and stereotyped patterns of behavior, activities, and interests. Children with autism also
experience sensory processing issues and it is a part of diagnostic criteria for Autism. The
executive functions are fundamental cognitive skills for achieving good performance in
life, as well as in the school and social environment, allowing people to face new and
complex situations and the major components of executive functions are working
memory, inhibition, and cognitive flexibility. Executive functions in an early age
evaluating a group of ASD preschool children and confirmed the presence of a significant
deficit in some aspects of executive functions in subjects with ASD. The research
indicated that children with ASD are often reported problem in executive function in
order to have poor working memory capacity, difficulties in switching attention between
tasks, and inhibition response problems, which can seriously affect their school
performance and everyday functioning. An attempt has been made to review on executive
functions in children with autism.
