On simplicity of formulas

Simple formula should contain only few quantifiers. In the paper the methods to estimate quantity and quality of quantifiers needed to express a sentence equivalent to given one.     

Working memory load and its impact on space-based and motion-based stimulus-response correspondence (SRC) effects

ABSTRACT

If spatial stimulus-response correspondence (SRC) effect results from automatic processes, cognitive load should not affect this effect. However, if spatial SRC effect is based on the interference of cognitive codes, cognitive load should influence it. Furthermore, the motion-based SRC effect should be affected by the cognitive load, as this SRC effect is related to the cognitive codes interference. In this study, participants performed combined tasks for space-based and motion-based SRC effects without working memory load (WML), or under spatial and verbal WML to see if cognitive load affects both SRC effects or just one. Results demonstrated that space-based SRC remained intact from WML, while the motion-based SRC was influenced by WML, although only in limited degree. This supports the notion that automatic processes underlie space-based SRC effect, whereas the motion-based SRC effect is related to cognitive codes interference, but the latter requires further investigation.     

Suicide Risk Protocols: Addressing the Needs of High Risk Youths Identified through Suicide Prevention Efforts and in Clinical Settings

Several agencies have emphasized the importance of establishing clear protocols or procedures to address the needs of youths who are identified as suicidal through suicide prevention programs or in emergency department settings. What constitutes optimal guidelines for developing and implementing such protocols, however, is unclear. At the request of the Substance Abuse and Mental Health Services Administration, we provide an overview of recommendations, as well as steps taken in conjunction with selected prevention programs and in emergency department settings to address the needs and improve the care of these youths.
