Counteraction between two kinds of conditioned inhibition training.

30 Jan 2008 In a Pavlovian fear-conditioning preparation, we investigated the effects of combining Pavlovian and explicitly unpaired inhibition treatments. A summation test for inhibition suggested a strong tendency toward unpaired inhibition when that ...

Does attention move or spread during mental curve tracing?

30 Jan 2008 There are two theories that attempt to explain how attention is deployed when lines are traced. Initially, it was believed that a covert zoom lens moved along the line. Recent evidence has, however, suggested that attention spreads along the line, ...

A comparison of discrimination and reversal learning for olfactory and visual stimuli in aged rats.

30 Jan 2008 The present study investigated age-related differences in discrimination and reversal learning for olfactory and visual stimuli in 6-month and 24-month-old rats. Rats were trained to discriminate between two pseudo-randomly selected odors or ...

Neurotoxic damage to the dorsomedial striatum exaggerates the behavioral influence of a context-specific inhibitory association mediated by the ventral hippocampus.

30 Jan 2008 This study investigated the role of the dorsomedial striatum (DMS) on the acquisition of a context-specific inhibitory association acquired during training on a simple visual discrimination task. The authors have previously shown that this ...

Sequence learning at optimal stimulus-response mapping: evidence from a serial reaction time task.

30 Jan 2008 We propose a new version of the serial reaction time (SRT) task in which participants merely looked at the target instead of responding manually. As response locations were identical to target locations, stimulus-response compatibility was maximal ...

ADHD and Stroop interference from age 9 to age 41 years: a meta-analysis of developmental effects.

27 Jan 2008 BACKGROUND: In this meta-analysis, we investigated whether response inhibition is sensitive to attention deficit hyperactivity disorder (ADHD) status and, if so, what influence maturation has on this attentional symptom of ADHD. METHOD: We examined ...

Impaired discrimination learning in mice lacking the NMDA receptor NR2A subunit.

26 Jan 2008 N-Methyl-D-aspartate receptors (NMDARs) mediate certain forms of synaptic plasticity and learning. We used a touchscreen system to assess NR2A subunit knockout mice (KO) for (1) pairwise visual discrimination and reversal learning and (2) ...

Chronic cocaine but not chronic amphetamine use is associated with perseverative responding in humans.

22 Jan 2008 RATIONALE: Chronic drug use has been associated with increased impulsivity and maladaptive behaviour, but the underlying mechanisms of this impairment remain unclear. We investigated the ability to adapt behaviour according to changes in reward ...

Deficits in social behavior and reversal learning are more prevalent in male offspring of VIP deficient female mice.

17 Jan 2008 Blockage of vasoactive intestinal peptide (VIP) receptors during early embryogenesis in the mouse has been shown to result in developmental delays in neonates, and social behavior deficits selectively in adult male offspring. Offspring of VIP ...

Independent, synchronous access to color and motion features.

16 Jan 2008 We investigated the role of attention in pairing superimposed visual features. When moving dots alternate in color and in motion direction, reports of the perceived color and motion reveal an asynchrony: the most accurate reports occur when the ...
