the aim of this study was to evaluate the effect of handedness and two practice types (explicit vs. implicit) on motor sequence learning. 60 girls (age range of 14 – 17 years old) were randomly assigned to four groups according to their handedness: right–handed-explicit, right–handed–implicit, left–handed-explicit, and left–handed-implicit. participants’ task was accuracy and time of sequential...

BACKGROUND Lung isolation skills, such as correct insertion of double lumen endobronchial tube and bronchial blocker, are essential in anesthesia training; however, how to teach novices these skills is underexplored. Our aims were to determine (1) if novices can be trained to a basic proficiency level of lung isolation skills, (2) whether video-didactic and simulation-based trainings are compar...

Several studies have shown marked differences in the neural localization of language functions in the brains of left-handed individuals when compared with right-handers. Previous experiments involving functional lateralization have demonstrated cerebral blood flow patterns that differ concordantly with subject handedness while performing language-related tasks. The effect of handedness on funct...

Examining organization of semantic information in the domain of Physics for PROBLEM SOLVING for experts versus novices: 1. Use of problem categories (models) to solve problem 2. Types of problem categories used 3. Knowledge associated with problem categories 4. Features of problems that affect how problem represented Operational definitions: PROBLEM REPRESENTATION: is a cognitive structure corr...

The aim of this retrospective study was to assess the presence of a possible association between handedness and the side of symptom dominance in 963 patients with Parkinson's disease (PD). In only 287 patients the hand dominance was registered. Out of 254 right-handed patients, 158 (62%) had a right-side dominance of PD symptoms, while 96 patients (38%) had left-lateralized symptom dominance (p...

Kleene algebras are an important class of algebraic structures that arise in diverse areas of computer science: program logic and semantics, relational algebra, automata theory, and the design and analysis of algorithms. The literature contains several inequivalent deenitions of Kleene algebras and related algebraic structures 2, 14, 15, 5, 6, 1, 10, 7]. In this paper we establish some new rela...

Recurring problems that are present in introductory and other programming courses have created a negative and pessimistic opinion among programming novices that enroll these courses. These problems have also created a fear about programming among programming novices which is passing from one generation to another. This fact is also supported by many researches which report that programming cour...
