The Cost of Regulating Effort: Reward and Difficulty Cues With Longer Prediction Horizons Have a Stronger Impact on Performance

Journal of Cognition
Many theories on cognitive effort start from the assumption that cognitive effort can be expended at will, and flexibly up- or down-regulated depending on expected task demand and rewards.

In Vivo Mapping of Catecholaminergic Loss and Iron Deposition in Huntington's Disease

Movement Disorders, EarlyView.
Abstract Background The pathophysiology of Huntington's disease (HD) remains obscure. Magnetic resonance imaging (MRI) can reveal in vivo molecular changes related to disease pathology. Objectives To investigate catecholaminergic neuronal integrity and subcortical brain iron accumulation in HD employing neuromelanin‐sensitive MRI, and quantitative ...

Executive function in schizophrenia and autism in adults shares common components separating high and low performance groups

Frontiers in Psychiatry
The profile of executive function (EF) in adults with Schizophrenia (SCZ) and autism spectrum disorder (ASD) remains unclear. This study aims to ascertain if distinct EF patterns can be identified between each clinical condition by comparing the ...

When conflict influences liking: The case of the Stroop task. [PDF]

PLoS ONE, 2018
Research suggests that cognitive conflict is accompanied by a negative signal. Building on the demonstrated role of negative affect in attitude formation and change, the present research investigated whether the experience of cognitive conflict ...

An Open‐Label Phase 1b Study of the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Activity of ANX005 in Patients with Huntington's Disease

Movement Disorders, EarlyView.
Complement activation is implicated in Huntington's disease; ANX005 is a potent inhibitor of component C1q. ANX005 exhibited a generally manageable safety profile with rapid reduction in C1q in the cerebrospinal fluid. Functional ability on composite Unified Huntington's Disease Rating Scale and total functional capacity was maintained, with potential ...

A functional dissociation of conflict processing within anterior cingulate cortex [PDF]

, 2008
Goal-directed behavior requires cognitive control to regulate neural processing when conflict is encountered. The dorsal anterior cingulate cortex (dACC) has been associated with detecting response conflict during conflict tasks. However, recent findings

Visual scanning patterns and executive function in relation to facial emotion recognition in aging [PDF]

, 2013
OBJECTIVE: The ability to perceive facial emotion varies with age. Relative to younger adults (YA), older adults (OA) are less accurate at identifying fear, anger, and sadness, and more accurate at identifying disgust.

Schizophrenia and reverse-Stroop interference in the group version of the Stroop and reverse-Stroop test.

The Japanese journal of psychology, 1993
Previous studies showed that attentional task performance of schizophrenics was significantly inferior to that of normals. The classical Stroop Color-Word Interference Test is an example of such attentional tasks and performance on the "reverse" Stroop task is reported to discriminate schizophrenics from normals better than the regular Stroop task ...

Perinatal women dominantly protect—rather than submissively cede—resources when interacting with threatening‐looking others

British Journal of Psychology, EarlyView.
Abstract When competing for resources, people appear particularly sensitive to social cues of threat, tending to submissively cede resources to more (vs. less) threatening‐looking others. This tendency appears especially pronounced among those that are physically weaker and thus more vulnerable to harm.
