Abstract

The expression of attentional blink (AB) in 24 schizophrenia inpatients was compared to 22 healthy subjects in a dual-target rapid serial visual presentation (RSVP) paradigm in which a sequence of discrete stimuli was presented in rapid succession. Correct identification of the first target led to poorer detection of the second one when they were interspersed by distractors. This second-target deficit constitutes the AB effect, which is most pronounced between 200 and 500 ms after the offset of the first target stimulus and steadily decays as the number of intervening distractors increases. Despite relatively poor performance in terms of target identification within RSVP streams, schizophrenia patients expressed an AB effect that was as clear as that seen in healthy subjects. Moreover, there was evidence for an enhanced AB effect in schizophrenia patients. This outcome contrasts with the robust finding that schizophrenia patients are attenuated in the expression of prepulse inhibition, another paradigm believed to assess attentional control. The present results add to the extensive literature on the nature and specification of attentional dysfunction implicated in schizophrenia.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.
