Raven Cpm Test

The Raven CPM Test, or Raven’s Coloured Progressive Matrices, is a nonverbal assessment of reasoning ability that measures how individuals identify relationships and patterns in visual information. Each item presents a geometric figure with a missing section, and the test taker selects the option that completes the pattern by comparing shapes, positions, colors, and other visual features. Designed for children and people with limited language or cognitive abilities, the test is widely used in behavioral research, educational assessment, and clinical settings to examine fluid reasoning while reducing the influence of verbal skills and formal schooling.

2016

Cognitive deficits are common in about one third of patients with amyotrophic lateral sclerosis, a neurological condition leading to progressive impairments in speech and movement abilities. To conduct cognitive tests in patients unable to speak or write a reliable and easy to administer eye-tracking paradigm was developed.

Tregs are potent suppressors of the immune system. There is a lack of unique surface markers to define them, hence, definitions of Tregs are primarily functional. Here we describe an optimized in vitro assay capable of identifying immune imbalance in subjects at risk to develop T1D.
