Handedness development during infancy could be represented as a progressive expansion of a hand-use preference across a wider range of increasingly complex skills. The goal of the present study was to explore the development of role-differentiated bimanual manipulation (RDBM) during infancy as an expansion of the development of handedness for acquiring objects and unimanual manipulation. Infant...

Investigations to explore human handedness have been conducted for ages. It is still uncertain what causes people to use the left or the right hand. Clues supporting the genetic origin of handedness have been accumulating and provide the best evidence. Nevertheless, in some populations there are different types of left-handers that do not seem to be explained solely by genes and differ from oth...

In this paper, we investigate group decision making problems with multiple types of linguistic preference relations. The paper has two parts with similar structures. In the first part, we transform the uncertain additive linguistic preference relations into the expected additive linguistic preference relations, and present a procedure for group decision making based on multiple types of additiv...

Iranian Rehabilitation Journal has the chance to issue a special issue on Occupational therapy and rehabilitation which has the perspective of health promotion. In this issue we will have 14 articles from the history to effectiveness of different skills/interventions of occupation therapy. We cover articles from child hood to adults to aged people. Evaluating the assessment tools such as the Pa...

Hand preferences of primates are discussed as part of the broad perspective of brain lateralization in animals, and compared with paw preferences in non-primates. Previously, it has been suggested that primates are more likely to express a species-typical hand preference on complex tasks, especially in the case of coordinated hand use in using tools. I suggest that population-level hand prefere...

Computational methods for discovering the preferences of individuals are useful in many applications. In this paper, we propose a method for learning valued preference structures, using a natural extension of so-called pairwise classification. A valued preference structure can then be used in order to induce a ranking, that is a linear ordering of a given set of alternatives. This step is reali...
