Does methylphenidate improve inhibition and other cognitive abilities in adults with childhood-onset ADHD?

Contains fulltext : 48908.pdf (publisher's version ) (Closed access)We examined the effect of methylphenidate (Mph) on inhibition and several other cognitive abilities in 43 adults with Attention Deficit Hyperactivity Disorder (ADHD) by use of Conners' Continuous Performance Test (CPT) and the Change Task (ChT), an extension of the Stop Signal Test (SST). In a double blind, cross-over, placebo controlled study with Mph, tests were administered during the third week of individually titrated treatment with Mph (maximum dose 1 mg / kg / day) and during the third week of treatment with placebo. We established large medication effects for commission errors, standard error of mean reaction time, and attentiveness on the CPT, as well as moderate medication effects for mean reaction time on the CPT and response re-engagement speed on the ChT. For Stop Signal Reaction Time (SSRT) on the ChT, we also established large effects of Mph, but only in a group of participants who showed slow SSRTs on placebo. Mph indeed ameliorates inhibition, which is the core problem of ADHD, and certain other cognitive abilities in adults with ADHD

Employability Skill Development of Mechanical Engineering Students Through Project Based Learning in Vocational High School in South Sulawesi

Abstract: Embedding employability skills in learning requires a learning model that allows effective in improving employability skills of students Learning model that if able to meet these expectations is project based learning. This study aims to determine the contribution of project based learning to employability skills of students of SMK Package Engineering Skills Engineering in South Sulawesi. This research uses quantitative approach with non experimental design with sample size 325 students. Data collection uses questionnaires to obtain data on project-based learning implementation and employability skills. The data of the research were analyzed by using descriptive analysis and regression analysis which previously conducted normality and linearity test. Based on the results of the research is known that the implementation of project based learning model contributes to the development of employability skill students of machining engineering SMK 59.8%

Critical social thinking

As technology, globalization, changing work demands, and a growing reliance on teams are changing the work environment, the social complexity surrounding work functions is increasing dramatically. While a variety of socially relevant knowledge, skills, and abilities (KSAs) have been examined, we argue that studying them in isolation is no longer sufficient, as individuals require a repertoire of KSAs that must be utilized in combination to be effective in complex social situations. Thus, we propose the construct critical social thinking (CST), a holistic, integrated approach to understanding the processes that enable individuals to function in such settings, and the KSAs that are necessary for each process. Because the significance of the CST construct is closely tied to the growing need for it in practice, we also integrate disparate training findings and link them to components of our conceptual model, enabling us to put forth initial insights regarding the approaches through which CST can be trained effectively
