The effects of pictures of emotional faces on tonic and phasic autonomic cardiac control in women and men.

The aim of the present study was to examine autonomic function in response to negatively and positively valenced pictures under different levels of conscious recognition. Heart period variability (HPV) and heart rate (HR) reactivity were studied in 53 ...

Age differences and divided attention: is there a general deficit?

It was the goal of this study to determine whether there were age differences specifically associated with the ability to simultaneously execute two tasks, and whether cognitive costs correlated across different situations. Eighty-one young and 86 older ...

Cerebral hemodynamics during discrimination of prosodic and semantic emotion in speech studied by transcranial doppler ultrasonography.

Simultaneous measurement of blood flow velocity (BFV) in the middle cerebral arteries was achieved by transcranial Doppler ultrasonography in 36 right-handed volunteers who were instructed to identify the emotion conveyed by prosody or semantics of a ...

Effect of manipulation and irrelevant noise on working memory capacity of patients with Alzheimers dementia.

The effect of manipulation and distracting noise on immediate serial recall was measured in patients with dementia of the Alzheimer type (DAT), neurologically healthy elderly individuals, and young adults. In Experiment 1, the authors compared serial ...

Neural substrates of perceptual enhancement by cross-modal spatial attention.

Orienting attention involuntarily to the location of a sudden sound improves perception of subsequent visual stimuli that appear nearby. The neural substrates of this cross-modal attention effect were investigated by recording event-related potentials to ...

Syntactic comprehension in Parkinsons disease: investigating early automatic and late integrational processes using event-related brain potentials.

Parkinsons disease (PD) has been associated with a general impairment of procedures and with an impairment of syntactic procedures in particular. The present study investigated comprehension processes in PD using event-related brain potentials (ERPs). PD ...

Functional representation of 3D space in endogenous attention shifts.

The aim of this study was to explore whether the attentional system, as far as an endogenous orienting is concerned, allocates resources along the sagittal plane and whether such a process is affected by, and is likely to be based on, different ...

Familial transmission of Continuous Performance Test behavior: attentional and impulsive response characteristics.

Continuous Performance Tests (CPTs) provide information on attentional processing and impulsive behavior. The results of previous research that used self-report measures have provided evidence for familial transmission (through genetic and/or ...

The physiological basis of clinical deficits in Parkinsons disease.

Despite the fact that Parkinsons disease (PD) is a relatively common neurological condition, the physiological derangements that result in its clinical features remain unclear. On combining findings from psychophysical, clinical and electrophysiological ...

Disrupting attention: the need for retrieval cues in working memory theories.

Sometimes in conversation, something is said that causes us to want to comment, but before our impending but implicit thoughts can be expressed, the conversation is disrupted. Later, we cannot recall what we wanted to say, but still later, we can. We ...
