Audio-visual speech perception is special

In face-to-face conversation speech is perceived by ear and eye. We studied the prerequisites of audio-visual speech perception by using perceptually ambiguous sine wave replicas of natural speech as auditory stimuli. When the subjects were not aware that the auditory stimuli were speech, they showed only negligible integration of auditory and visual stimuli. When the same subjects learned to perceive the same auditory stimuli as speech, they integrated the auditory and visual stimuli in a similar manner as natural speech. These results demonstrate the existence of a multisensory speech-specific mode of perception.     

Inherent biases in decision support systems: the influence of optimistic and pessimistic DSS on choice,affect, and attitudes

This study investigates the influence of a decision aid on decision makers' model‐based choices, emotions during the use of the model, and attitudes towards the model. A time allocation decision model was biased to purposefully provide optimistic or pessimistic criterion levels, on which subjects based their allocations. The results of our experiment indicate that the degree of “optimism” and “pessimism” inherent in the decision model had a significant impact on the decision maker's choices of criterion values, with optimism leading to higher criterion level choices and pessimism to lower levels. Furthermore, compared to pessimistic models, optimistic models significantly improved the decision makers' emotional states and, to some degree, their attitudes towards the decision aid. The implications of these conscious and sub‐conscious influences on decision makers' choices, emotions, and attitudes are discussed and the need for model‐builders and users to be aware of them is highlighted.

MCDM methods in strategic planning of forestry on state‐owned lands in Finland: applications and experiences

The forests in Finland have been under intensive planning for decades. Currently, mathematical programming is widely used in planning of wood production. Today's multi‐functional forestry, however, calls for more flexible decision support methods. MCDM tools have been used in responding to fresh planning challenges. For example, the Finnish Forest and Park Service, entrusted with the care of the vast majority of state‐owned natural resources in Finland, endeavours to produce large‐scale natural resource plans satisfying the needs of both economic, social, and ecological sustainability. Participatory approach is applied in the process. Several forestry applications of MCDM methods, particularly those making use of the AHP or the HIPRE program, have been presented. Also, the outranking methods ELECTRE and PROMETHEE have been tested. Due to the nature of forestry applications, statistical techniques for analysing uncertainties in pairwise comparisons and for utilizing interval judgement data have been developed to improve the usability of the AHP. Recently, a hybrid method called A'WOT, making use of the AHP and SWOT, was also introduced into strategic forest planning. This paper summarizes the experiences gained in applying a MAVT and two outranking methods in connection with a participatory natural resource planning process in Finland. In addition, some results of the method development work related to application needs are briefly presented. The details of the planning cases reviewed here have previously been presented in forestry journals. The purpose of this paper is not only to show how MCDM methods have been applied in forestry, but also to discuss the usability and usefulness of MCDM methods from the viewpoint of supporting forestry decision making—and how they might further be improved. Also, some perspectives for the future development work of MCDM applications in the field of natural resource management are focused on. As a conclusion, the use of more than just one MCDM method in a single planning process is seen usually recommendable. In addition, developing hybrid MCDM methods is regarded as a potential direction for future research. Also, closer co‐operation between method developers and appliers is called for to produce more useful applications. Copyright © 2002 John Wiley & Sons, Ltd.     

An Early History of Multiple Criteria Decision Making

This historical note is based on a plenary talk ‘A History of Early Developments in Multiple Criteria Decision Making’, presented by Stanley Zionts at the 21st International Conference on Multiple Criteria Decision Making held in Jyväskylä, Finland, June 2011. It draws heavily on our book, Multiple Criteria Decision Making: From Early History to the 21st Century, published by World Scientific, Singapore, 2011. Copyright © 2013 John Wiley & Sons, Ltd.     

Cognitive Outcome in Acute Sporadic Encephalitis

Acute encephalitis is an inflammation of the brain parenchyma. In the United States, 20,000 cases occur yearly. A variety of cognitive deficits, often the sole cause of disability, may persist after the acute stage. Still, infectious diseases tend to be covered only briefly in neuropsychological handbooks. Recent literature demonstrates the heterogeneity of both amnestic disorders and the outcome following encephalitides. Herpes Simplex virus (HSV), the most common single etiology of sporadic encephalitis, usually causes the most severe symptoms. Modern antiviral medication, however, seems to improve the cognitive outcome. Much less is known about non-HSV encephalitides, where both mild and severe defects have been observed. This article summarizes the current knowledge and also calls upon a more active neuropsychological research in the area.     

Personal project level of abstraction and project conflict: relations to psychological well‐being

The study examined the relations between personal project level of abstraction, project conflict and psychological well‐being. The revised Little's Personal Project Inventory was completed by 167 adults around the age of 30, and the amount of conflict experienced between the projects as well as the level of depression and life satisfaction were rated. Level refers to the degree of generality versus specificity of the projects. Project level of abstraction and conflict were negatively related to each other. Abstract projects were appraised as meaningful and they tended to be stressful. Abstract and stressing projects were typical of depression and of single persons. Conflict was interpreted practically, reflecting, for instance, lack of time, and it characterized less meaningful projects. Blue collar workers had less conflicting project systems than groups with middle level or academic education. Project level of abstraction and project conflict were not related to life satisfaction or gender. Copyright © 2000 John Wiley & Sons, Ltd.     

Choice Behaviour in a Computer-Aided Multiattribute Decision Task

Choice behaviour in an interactive multiple-criteria decision-making environment was examined experimentally. The main purpose was to investigate whether subjects are more comfortable in processing criterion/attribute information simultaneously (in parallel) or sequentially. As a research instrument, three different interactive software systems were used on a microcomputer by management students at the Helsinki School of Economics and Business Administration and the Institute of National Economy in Moscow to solve essentially the same problem of buying/leasing a home tailored to the respective decision environments. The experiments also provided us with a possibility to learn useful lessons about how human subjects make computer-supported choices. The results of the experiments are discussed. Furthermore, questions for future research are suggested. © 1997 John Wiley & Sons, Ltd.
