Resistance to change within heterogeneous response sequences.
29 Jun 2009 
Three experiments investigated how instrumental and Pavlovian contingencies contribute to resistance to change (RTC) in different ordinal response positions within heterogeneous response sequences in pigeons. RTC in the initial and terminal response ...

Instinctive modulation of cognitive behavior: a human evoked potential study.
29 Jun 2009 Successful adaptive behavior requires fast information processing. Behavioral switches may be necessary in response to threatening stimuli or when anticipated outcomes fail to occur. In this study, we explored the cortical processing of these two ...

Estimating distance in real and virtual environments: Does order make a difference?
29 Jun 2009 In this investigation, we examined how the order in which people experience real and virtual environments influences their distance estimates. Participants made two sets of distance estimates in one of the following conditions: (1) real environment ...

Nuclei accumbens phase synchrony predicts decision-making reversals following negative feedback.
8 Jun 2009 The nucleus accumbens plays a key role in reinforcement-guided behaviors. Here, we report that electrophysiological oscillatory phase synchrony between the two nuclei accumbens may play a crucial role in using negative feedback to guide decision ...

Adaptive coding of action values in the human rostral cingulate zone.
8 Jun 2009 Correctly selecting appropriate actions in an uncertain environment requires gathering experience about the available actions by sampling them over several trials. Recent findings suggest that the human rostral cingulate zone (RCZ) is important for ...

The effect of 40 h constant wakefulness on task-switching efficiency.
30 May 2009 This study investigated efficiency of switching between different tasks in 12 male participants (19-30 years) during 40 h of constant wakefulness. As index of task-switching efficiency, switch costs in reaction time were assessed every 3 h under ...

The representational locus of spatial influence on backward inhibition.
30 May 2009 When one is sequentially switching among three tasks, performance is impaired when tasks alternate (ABA) relative to when one is switching between all three tasks (CBA), an effect known as backward inhibition (BI). BI is not observed when component ...

Forward and backward repetition blindness in speed and accuracy.
30 May 2009 Repetition blindness (RB) was investigated in a new paradigm in which effects could stem from items preceding or following a target. Speeded-response tasks were used in which 3 critical items (C1, C2, and C3) were sequentially presented on each ...

Fractionating the binding process: neuropsychological evidence from reversed search efficiencies.
30 May 2009 The authors present neuropsychological evidence distinguishing binding between form, color, and size (cross-domain binding) and binding between form elements. They contrasted conjunctive search with difficult feature search using control ...

16 May 2009 Normally, mice sleep during the day and are active at night. In Huntington's disease mice (R6/2 line) this circadian pattern disintegrates progressively over the course of their illness. Cognitive decline and apathy in R6/2 mice can be improved with ...
