The coding of stimuli and responses is crucial for human behaviour. Here, we focused primarily on the response codes (or response categories). As a method, we applied a combined dual-task and task-switch paradigm with a fixed task-to-hand mapping. ...

29 Sep 2008 In this research, the controversial issue of whether the central bottleneck can be bypassed through task automatization was investigated. To examine this issue, participants received six single-task practice sessions with an auditory-vocal task (low ...

29 Sep 2008 Task switching research has revealed that task changes lead to a performance switch cost. The present study focuses on the organization of task components in the task set. Three different views of task set organization have been distinguished and ...

Global inhibition and midcourse corrections in speeded aiming.
29 Sep 2008 When some perceptual-motor relationships are reversed, participants might adopt a global inhibition strategy that replaces all normal movements with reversed movements. In two experiments, participants practiced moving a cursor from a start position ...

29 Sep 2008 The avian visual "Wulst" is a target of the ascending thalamofugal visual pathway. In pigeons (Columba livia), lesion damage to the Wulst has little effect on simple visual discriminations, but impairs performance on tasks such as reversal learning. ...

Subchronic MK-801 behavioural deficits in rats: partial reversal by the novel nitrate GT 1061.
8 Sep 2008 Cognitive deficits are a core feature of schizophrenia that may be linked to abnormalities in GABA and nitric oxide (NO). Subchronic treatment with glutamate receptor antagonists produces similar deficits, providing a useful model to examine ...

30 Aug 2008 Gamma-aminobutyric acid (GABA)A receptors characterized by the presence of the alpha3 subunit are the major GABAA receptor subtype expressed in brain stem monoaminergic nuclei. These alpha3-GABAA receptors are therefore in a unique position to ...

30 Aug 2008 This study demonstrated effects of age, education, and sex on complex reaction time in a large national sample (N = 3,616) with a wide range in age (32-85) and education. Participants completed speeded auditory tasks (from the MIDUS [Midlife in the ...

Cognitive development in macaques: attentional set-shifting in juvenile and adult rhesus monkeys.
29 Aug 2008 In humans and nonhuman primates, the structure and function of frontal cortical regions of the brain are not completely developed until early adulthood. How this cortical development affects cognitive function continues to be elucidated. To that ...

20 Aug 2008 Impaired fetal development has been linked with deficits in behavioural and emotional development during postnatal life. In order to investigate the mechanisms underlying this relationship, we studied the effect of acute stress at two different ...
