An exemplary outline of multiple levels of learning that contribute to card sorting performance.Computerized WCST.The present study utilizes the computerized WCST12,35,52,53. On the initial trial, a stimulus card (four green crosses) could be sorted according to thecolorcategory (inner left key c...
Participants then completed the Wisconsin Card Sorting Test (WCST), a well-studied task of cognitive control during rule learning. High-lethality attempters demonstrated a pattern of deficits involving poor conceptual reasoning, perseverative errors and total errors. Compared to low-lethality ...
‘I can use the onscreen keyboard to type’, ‘I can set up a password to lock/unlock the device’) on a 5-point Likert-type scale (1—Never tried to 5—Very
The primary aim of the present study is to investigate whether a novel cognitive training programme based on Structure Learning can improve cognitive flexibility performance in a healthy adult population. The near-transfer benefits of the training are first evaluated within the Structure Learning task i...
Finally, all participants were administered a small battery of neurospsychological tests assumed to rely (in varying degrees) on prefrontal structures and/or the media temporal lobe memory system, namely the short form of the WCST (WCST-64; Axelrod et al., 1992), a test of mental flexibility...
Therefore, we tend to classify ‘eagles’ as birds more easily and more accurately than ‘penguins’. Here we show that despite their impaired executive functions, patients with schizophrenia have sufficient capacities to learn visual prototypes of perceptual categories. Access through your organization ...
probabilistic. However, there is emerging evidence that adults with OCD also display abnormal choice switching on the WCST.15Researchers theorize that this aberrant choice switching is attributed to “overcomplicated exploration,” in which adults with OCD attempt to evaluate too many rules at once....
(\tau \)represent the slow gain or the fast gain respectively to reach the saturation level of the estimated SL scores. The x-intercept was almost zero (\({x}_{0}\)= − 0.39), implying that participants had already started to learn the probabilistic associations of the sequences from ...
Patients were impaired at reward learning from trial-and-error feedback but showed a preserved ability to learn to predict reward based on episodic memory. Regard- ing effects of cerebellar TMS on performance monitoring, a recent study reported a reduction of the ERN [142]. Due to the ...
