BOLD activity during mental rotation and viewpoint-dependent object recognition.

We measured brain activity during mental rotation and object recognition with objects rotated around three different axes. Activity in the superior parietal lobe (SPL) increased proportionally to viewpoint disparity during mental rotation, but not during ...

fMRI study of cognitive interference processing in females with fragile X syndrome.

Females with fragile X syndrome, the most common form of inherited developmental and learning problems, are known to be impaired in executive function. The current study is the first to investigate the performance of females with fragile X on a cognitive ...

Reliability and validity of day-to-day blood flow velocity reactivity in a single subject: an fTCD study.

To evaluate the within-subject variability of repeated task-induced blood flow velocity (BFV) change, we measured the haemodynamics of the anterior and middle cerebral arteries of the same volunteer on 20 consecutive working days during the performance ...

Cord serum ferritin concentrations and mental and psychomotor development of children at five years of age.

OBJECTIVE: Our purpose was to evaluate the association between fetal iron status and mental and psychomotor development at 5 years of age. STUDY DESIGN: We evaluated the association of fetal iron status (umbilical cord serum ferritin concentrations) with ...

The relation between task history and movement strategy.

In the present study, we examine whether subjects hit identical moving targets differently when the task history is different. Twelve subjects each took part in four experimental sessions. Each session consisted of recurring targets that were the same in ...

An assessment of surgical education.

A review of the dramatic changes in society, science and medicine that have affected the time we have available for education of students and residents. Reference is made to distance learning, educational efficiency and mental practice as concepts that ...

Featural vs. configurational information in faces: a conceptual and empirical analysis.

The perception and memory of faces have been accounted for by the processing of two kinds of facial information: featural and configurational. The starting point of this article is the definition and accepted usage of these two concepts of facial ...

Relevant EEG features for the classification of spontaneous motor-related tasks.

There is a growing interest in the use of physiological signals for communication and operation of devices for the severely motor disabled as well as for healthy people. A few groups around the world have developed brain-computer interfaces (BCIs) that ...

Implicit and explicit processes in a hypothesis testing task.

We present the results of two experiments investigating the factors that determine responding on the pseudo-diagnosticity task. In Expt 1 we manipulated peoples beliefs about the degree to which an initial piece of evidence supported a focal hypothesis ...

Latent inhibition as a function of schizotypality and gender: implications for schizophrenia.

In three within-subject experiments, we demonstrated that preexposure to an irrelevant stimulus interfered with performance when that stimulus subsequently predicted the correct location of a target stimulus. This latent inhibition-like effect (LI) was ...
