Dopamin und kognitive Handlungssteuerung: Flexibilität und Stabilität in einem Set-Shifting Paradigma
… und DRD4 Exon III sowie das Geschlecht eingesetzt. In der dritten Studie sollte eine Dopaminausschüttung experimentell durch die Darbietung von Signalen einer potenziellen Belohnung (Geldgewinn) stimuliert werden. Hierdurch sollten die beobachteten Zusammenhänge aus den ersten beiden Studien …

An investigation of set shifting in anorexia nervosa and clinical research portfolio
… deficits in cognitive processes, in particular set shifting, might contribute to the development and maintenance of anorexia nervosa (AN). Results of studies of set shifting have been mixed. There has been considerable variability in tests used to measure set shifting and a lack of homogeneity …

Set shifting ability of rats perinatally exposed to bisphenol A and a high fat diet
… exposed rats were tested on an extra-dimensional set-shifting task. A rotating plus maze with black/white and rough/smooth arms was used. Final analysis indicates that there were no significant treatment differences for the number of trials needed to reach criterion during the initial …

The role of awe in cognitive restructuring, cognitive reflection, and set shifting: a psychotherapy analogue study
Awe has the properties of prompting individuals to reevaluate their worldview, rely less on heuristics, and enhance mental flexibility. This is the first known study assessing the utility of awe in a psychotherapy analog. Participants were randomized into either an awe induction or neutral group. …

Prenatal PolyI:C induced schizophrenia-like cognitive inflexibilities in the male, but not female, rat adult offspring
… such as working memory, decision making and set-shifting. Interestingly, patients diagnosed with different psychiatric disorders are also impaired in executive functions, especially in the set-shift domain, often measured by the Wisconsin Card Sorting Task (WCST). Set-shifting is an essential …

Executive Function and Parenting Among Latinx Caregivers of Young Children
… two core dimensions of EF, working memory and set-shifting abilities, are related to parenting behaviors in a sample of Latinx caregivers of young children experiencing low income. Positive parenting was measured using a multi-method approach including video-coded observations, parent …

Theory of Mind Reasoning and its Relationship to Executive and Social Functioning in 10-Year-Olds
… In addition, working memory, inhibition, and set-shifting abilities were assessed, along with empathy and bullying/victimization. Results show that cognitive ToM is more advanced than affective ToM in this age group. While cognitive false-belief was positively associated with inhibition and …

To Eat or Not to Eat: An Investigation of Meal Skipping on Cognitive Functioning
… working memory, attention, processing speed, set shifting, eating disorder symptomology, depression, and anxiety. </p><p> Results revealed that participants in the lunch condition had better short-term memory performance relative to participants in the lunch omission condition. No differences …

Stress, Monoamines, and Cognitive Flexibility
… cognitive function using attentional set-shifting tasks, microdialysis, and immunohistochemistry. CRF microinfusion into the LC and DRN produced dose-dependent effects on distinct cognitive functions. Low doses CRF in the LC facilitated set-shifting and increased c-fos expression in …

Neuropsychological Comparisons Of Obsessive-Compulsive Disorder Subtype And Body Dysmorphic Disorder Symptomatology
… symptoms were a significant predictor of set-shifting, ordering symptoms were a significant predictor of inhibition, and washing symptoms were a significant predictor of emotional interference. BDD symptoms were found to be a significant predictor of memory ability and set-shifting …

Exploration of cognitive and neurochemical deficits in an animal model of schizophrenia. Investigation into sub-chronic PCP-induced cognitive deficits using behavioural, neurochemical and electrophysiological techniques; and use of receptor-selective agents to study the pharmacology of antipsychotics in female rats.
… The main tests used were attentional set-shifting, operant reversal learning, and novel object recognition tasks. The pharmacology of antipsychotics was studied in the reversal learning task using receptor selective compounds. Following this, experiments were carried out using in vitro …

Assessing the effects of adolescent PCB exposure on executive functions in humans and animals
… on cognitive flexibility, using an operant set-shifting task, and response inhibition, using a differential reinforcement of low rates of responding (DRL) task. An additional goal was to determine whether exposure during this period would lead to long-lasting changes in dopamine transporter …

Electroencephalographic and Cognitive Underpinnings of Inhibitory Control in Obsessive-Compulsive Disorder: From Actions to Thoughts
… (ii) They also present deficits in attentional set-shifting in an extra-dimensional set-shifting task; (iii) OCD is marked by difficulties in the ability to control thoughts, as demonstrated by a Retrieval-Induced Forgetting (RIF) paradigm; (iv) Deficits in inhibitory control correlate with …

Alterations in executive functioning induced by repeated amphetamine exposure
… has shown that two types of executive functions, set shifting and working memory (WM), are disrupted by AMPH sensitization and that these cognitive domains are impaired in schizophrenics and stimulant abusers. We assessed the effects of AMPH sensitization on behavioural flexibility using a …

Understanding comorbid ADHD and cocaine abuse: consequences of adolescent medication in an animal model
… performance in adolescent SHR during a strategy set-shifting task and not increase cocaine abuse risk in adult SHR after adolescent d-amphetamine was discontinued. Across experiments, adult SHR acquired cocaine self-administration faster than control strains and also were more sensitive to …

NICOTINE WITHDRAWAL AND DEFICITS IN COGNITIVE FLEXIBILITY: POSSIBLE TIES TO ABERRATIONS IN FRONTOSTRIATAL BDNF SIGNALING
… flexibility in mice using an operant strategy set-shifting task. Because frontostriatal circuits are critical for cognitive flexibility and brain-derived neurotrophic factor (BDNF) modulates glutamate plasticity, we also explored the effects of nicotine withdrawal on these neurochemical …

Inflexibility and Vulnerability to Depression
… for these hypotheses was found. Deficits in set-shifting predicted greater prospective symptoms of depression. Extreme attributions, brooding, and deficits in cognitive inhibition, autonomic reactivity and recovery interacted with negative life events to predict prospective symptoms of …

Episodic Memory during Middle Childhood: Active vs. Passive Processing
… in memory task performance. Specifically, set-shifting and working memory predicted a unique amount of variance in memory task performance. The results suggest that explicit memory may require certain executive processes more than others, and that active and passive processing may enhance …

Commonalities And Differences In Visual And Auditory Multistability
… in executive function (inhibitory control and set-shifting), creativity and personality traits have common relationships with perceptual switching in adults and children. A series of five experiments (four studies) were conducted. In Study 1 (two experiments), perceptual switching behaviour of …
