=== Clinical diagnostics === In nosological literature relating to the symptom or disorder of apathy, clinicians have used cognitive inertia as one of the three main criteria for diagnosis. The description of cognitive inertia differs from its use in cognitive and industrial psychology in that lack of motivation plays a key role. As a clinical diagnostic criterion, Thant and Yager described it as "impaired abilities to elaborate and sustain goals and plans of actions, to shift mental sets, and to use working memory". This definition of apathy is frequently applied to onset of apathy due to neurodegenerative disorders such as Alzheimer's and Parkinson's disease but has also been applied to individuals who have gone through extreme trauma or abuse.
== Neural anatomy and correlates ==
=== Cortical === Cognitive inertia has been linked to decreased use of executive function, primarily in the prefrontal cortex, which aids in the flexibility of cognitive processes when switching tasks. Delayed response on the implicit associations task (IAT) and Stroop task have been related to an inability to combat cognitive inertia, as participants struggle to switch from one cognitive rule to the next to get the questions right. Before taking part in an electronic brainstorming session, participants were primed with pictures that motivated achievement to combat cognitive inertia. In the achievement-primed condition, subjects were able to produce more novel, high-quality ideas. They used more right frontal cortical areas related to decision-making and creativity. Cognitive inertia is a critical dimension of clinical apathy, described as a lack of motivation to elaborate plans for goal-directed behavior or automated processing. Parkinson's patients whose apathy was measured using the cognitive inertia dimension showed less executive function control than Parkinson's patients without apathy, possibly suggesting more damage to the frontal cortex. Additionally, more damage to the basal ganglia in Parkinson's, Huntington's and other neurodegenerative disorders have been found with patients exhibiting cognitive inertia in relation to apathy when compared to those who do not exhibit apathy. Patients with lesions to the dorsolateral prefrontal cortex have shown reduced motivation to change cognitive strategies and how they view situations, similar to individuals who experience apathy and cognitive inertia after severe or long-term trauma.
=== Functional connectivity === Nursing home patients who have dementia have been found to have larger reductions in functional brain connectivity, primarily in the corpus callosum, important for communication between hemispheres. Cognitive inertia in neurodegenerative patients has also been associated with a decrease in the connection of the dorsolateral prefrontal cortex and posterior parietal area with subcortical areas, including the anterior cingulate cortex and basal ganglia. Both findings are suggested to decrease motivation to change one's thought processes or create new goal-directed behavior.
== Alternative theories == Some researchers have refuted the cognitive perspective of cognitive inertia and suggest a more holistic approach that considers the motivations, emotions, and attitudes that fortify the existing frame of reference.
=== Alternative paradigms ===
==== Motivated reasoning ==== The theory of motivated reasoning is proposed to be driven by the individual's motivation to think a certain way, often to avoid thinking negatively about oneself. The individual's own cognitive and emotional biases are commonly used to justify a thought, belief, or behavior. Unlike cognitive inertia, where an individual's orientation in processing information remains unchanged either due to new information not being fully absorbed or being blocked by a cognitive bias, motivated reasoning may change the orientation or keep it the same depending on whether that orientation benefits the individual. In an extensive online study, participant opinions were acquired after two readings about various political issues to assess the role of cognitive inertia. The participants gave their opinions after the first reading and were then assigned a second reading with new information; after being assigned to read more information on the issue that either confirmed or disconfirmed their initial opinion, the majority of participants' opinions did not change. When asked about the information in the second reading, those who did not change their opinion evaluated the information that supported their initial opinion as stronger than information that disconfirmed their initial opinion. The persistence in how the participants viewed the incoming information was based on their motivation to be correct in their initial opinion, not the persistence of an existing cognitive perspective.
==== Socio-cognitive inflexibility ==== From a social psychology perspective, individuals continually shape beliefs and attitudes about the world based on interaction with others. What information the individual attends to is based on prior experience and knowledge of the world. Cognitive inertia is seen not just as a malfunction in updating how information is being processed but as the assumptions about the world and how it works can impede cognitive flexibility. The persistence of the idea of the nuclear family has been proposed as a socio-cognitive inertia. Despite the changing trends in family structure, including multi-generational, single-parent, blended, and same-sex parent families, the normative idea of a family has centered around the mid-twentieth century idea of a nuclear family (i.e., mother, father, and children). Various social influences are proposed to maintain the inertia of this viewpoint, including media portrayals, the persistence of working-class gender roles, unchanged domestic roles despite working mothers, and familial pressure to conform. The phenomenon of cognitive inertia in brainstorming groups has been argued to be due to other psychological effects such as fear of disagreeing with an authority figure in the group, fear of new ideas being rejected and the majority of speech being attributed to the minority group members. Internet-based brainstorming groups have been found to produce more ideas of high-quality because it overcomes the problem of speaking up and fear of idea rejection.
