Prior to the study, Larry engaged in
perseverative speech about candy he observed in magazines.
Consequently, this dysfunctional processing develops into, or initially causes,
perseverative thinking and emotional coping or develops clinical tendencies and cognitive irregularities, playing a major role in psychopathology.9 The metacognitive theory is a comprehensive explanation of metacognitions that monitor and regulate the executive self-regulatory system.
According to the results of rapid juvenile test battery, modified rats exhibited abnormalities in ASD-relevant phenotypes, including juvenile play,
perseverative behaviors, and sensorimotor gating (11).
reported some side effects that included transient headache, confusion, loss of motivation,
perseverative behavior and incontinence and no patient showed memory and attention disorders (3, 13, 14).
Perseverative Thinking Questionnaire (PTQ; Ehring et al., 2011).
The total number of errors,
perseverative errors, non-perseverative errors and completed categories were used in our study to assess neurocognitive flexibility.
For example, Davis and Nolen-Hoeksema (2000) examined cognitive flexibility in a card-sorting task and found that people who tend to ruminate on negative thoughts and feelings were more likely to make
perseverative errors in an experimental task, indicating cognitive rigidity.
The WCST assesses cognitive flexibility and set-shifting abilities, which are evaluated by a number of trials, total errors,
perseverative responses,
perseverative errors, non-perseverative errors, completed categories and a failure to maintain the set (16).
It is thought that the type of error in CDT (i.e., the placement of numbers, the representation of clock, the presence of
perseverative errors) may be distinctive for dementia syndromes.
The computerized version of the WCST contains 11 measures including the number of categories completed, the number of trials, the number of correct responses, the number of errors, the number of
perseverative responses, the number of
perseverative errors, the number of nonperseverative errors, the number of trials to complete the first category, the percentage of conceptual response, failure to maintain set, and learning to learn [16].
The basic premise of the S-REF model is that psychological disorders are the result of self-regulatory strategies dominated by
perseverative thinking (worry, rumination, and excessive attention to threat, e.g., self-monitoring).
Objects of high interest were rotated with objects that were not a
perseverative interest for the individual child.
