The Change Processes in Selective Attention during Adulthood. Inhibition or Processing Speed?

Several authors state that it experiences a decline after 20 years, although there is no agreement regarding the cognitive processes that explain it.

[Classification statistical techniques: an applied and comparative study].

The aim of this article is to assess and compare three classification statistical techniques--logistic regression, discriminant analysis and classification trees--to identify the personality characteristics associated with the risk of suffering from ischemic cardiovascular acute episodes (ICAE). The sample comprised 313 participants, men and women, aged from 36 to 80. Participants were divided into two groups: a clinical group of patients (n = 143) who were diagnosed as suffering from ICAE, and a control group (n = 170).
