is a way to improve their inhibitory control and their cognitive flexibility. These skills allow children to manage their emotional responses. These interventions include teaching children executive function-related skills that provide the steps necessary to implement them during classroom activities and educating children on how to plan their actions before acting upon them. Executive functioning skills are how the brain plans and reacts to situations. Offering new self-regulation strategies allow children to improve their executive functioning skills by practicing something new. It is also concluded that mindfulness practices are shown to be a significantly effective intervention for children to self-regulate. This includes biofeedback-enhanced relaxation. These strategies support the growth of children's executive functioning skills. Problem-solving model Yet another model of executive functions is a problem-solving framework where executive functions are considered a macroconstruct composed of subfunctions working in different phases to (a) represent a problem, (b) plan for a solution by selecting and ordering strategies, (c) maintain the strategies in short-term memory in order to perform them by certain rules, and then (d) evaluate the results with error detection and error correction. Lezak's conceptual model One of the most widespread conceptual models on executive functions is Lezak's model. This framework proposes four broad domains of volition, planning, purposive action, and effective performance as working together to accomplish global executive functioning needs. While this model may broadly appeal to clinicians and researchers to help identify and assess certain executive functioning components, it lacks a distinct theoretical basis and relatively few attempts at validation. Miller and Cohen's model In 2001, Earl Miller and Jonathan Cohen published their article "An integrative theory of prefrontal cortex function", in which they argue that cognitive control is the primary function of the prefrontal cortex (PFC), and that control is implemented by increasing the gain of sensory or motor neurons that are engaged by task- or goal-relevant elements of the external environment. In a key paragraph, they argue: Miller and Cohen draw explicitly upon an earlier theory of visual attention that conceptualises perception of visual scenes in terms of competition among multiple representations – such as colors, individuals, or objects. Selective visual attention acts to 'bias' this competition in favour of certain selected features or representations. For example, imagine that you are waiting at a busy train station for a friend who is wearing a red coat. You are able to selectively narrow the focus of your
