Delay discrimination and reversal eyeblink classical conditioning in abstinent chronic alcoholics.
28 Feb 2008 
Evidence has shown that alcoholism leads to volume reductions in brain regions critical for associative learning using the eyeblink classical conditioning paradigm (EBCC). Evidence indicates that cerebellar shrinkage causes impairment in simple ...

Presentation modality influences WAIS Digit Span performance in younger and older adults.
27 Feb 2008 
The WAIS-R Digit Span subtests require oral presentation of digits. Older adults with hearing impairments may have reduced recall due to deficits in hearing. It is also possible that older adults' recall is influenced by recall superiority for ...

26 Feb 2008 Human MDMA (R,S-3,4-methylenedioxymethamphetamine) users display selective cognitive deficits after acute MDMA exposure, frequently attributed to serotonin deficits. We postulated that MDMA will compromise executive function in primates and that an ...

21 Feb 2008 This study investigated whether children with autism spectrum disorders (ASDs) exhibit formal thought disorder (FTD), and whether this is related to ASD symptoms, executive control, and anxiety. Participants aged 8-17 with ASDs exhibited ...

18 Feb 2008 Capacity limits in linguistic short-term memory (STM) are typically measured with forward span tasks in which participants are asked to recall lists of words in the order presented. Using such tasks, native signers of American Sign Language (ASL) ...

Keeping the goal in mind: prefrontal contributions to spatial navigation.

rec_pub_18387640-keeping-goal-mind-prefrontal-contributions-spatial-navigation.htm
13 Feb 2008 The medial prefrontal cortex (mPFC) of the rat plays an essential role in behavioral flexibility, as lesions or inactivations of this region impair shifting between strategies or attentional sets using a variety of different behavioral tests. In the ...

Focal basal ganglia lesions are associated with impairments in reward-based reversal learning.
5 Feb 2008 The basal ganglia (BG) are thought to play a key role in learning from feedback, with mesencephalic dopamine neurons coding errors in reward prediction, thereby mediating information processing in the BG and the prefrontal cortex. In the present ...

Evidence that judgments of learning are causally related to study choice.
30 Jan 2008 Three experiments investigated whether study choice was directly related to judgments of learning (JOLs) by examining people's choices in cases in which JOLs were dissociated from recall. In Experiment 1, items were given either three repetitions or ...

Location-specific versus hemisphere-specific adaptation of processing selectivity.
30 Jan 2008 Current theories of cognitive control assume that processing selectivity is adjusted according to the utility of processing task-irrelevant stimulus features. Consistently, interference evoked by flanker stimuli is reduced when the proportion of ...
