Perception research

Over the last century a number of theories have been proposed to account for perception. Each theory, however, has encountered difficulties in accounting for some of the above-discussed phenomena of perception. And most perception researchers today do not adhere to one theory, instead they believe those aspects of the theories that have some experimental support, or that seem most logical and sound.

The new-terrorism discourse is a discourse that fits very well in modern mass media because it presents terrorism as a societal, catastrophic risk. After 9/11 the terrorism risk is interpreted as a risk for us . Results from risk perception research shows that people tends to highly rate risks that can harm themselves or their family are perceived to be caused by something out of the person s control have large consequences and are threats to societies rather than individuals (Sjoberg, 2004). Consequently, the implications of the new terrorism-discourse raise pubHc fear and powerlessness. The society must then be structured in a way that reduces availability, opeimess and pubHc access. Crenshaw (2008) asks why the idea of the new terrorism is so attractive. Her answer is that one reason may be that the conception of the new terrorism supports the case for major poHtical change. 

In pattern perception, researchers are now flnding that some features of pattern form and shape have signiflcant impact on our response. A checkerboard pattern was observed to evoke higher response compared to patterns of stripes, concentric circles and radial lines [19—21]. This response is found to be sensitive to the size of the check...

In as far as hazard perception deals with the understanding of simple perceptual realities, i.e., with the perception of objects, tones, smells or tactile sensations, the general principles which have been established over the course of many years in the field of perception research (see Krech Crutchfield, 1973 Schmidt, 1973 Metzger, 1975 Hochberg, 1977) can be applied here as well. We know that certain physical processes which occur in the presence of a person, such as electromagnetic waves, vibrations of the air, oscillations, etc., can lead to changes in the senses. 

To date, researchers have identified more than 100 different molecules, composed of up to 13 atoms, in the interstellar medium [16]. Most were initially detected at microwave and (sub)millimetre frequencies, and the discoveries have reached far beyond the mere existence of molecules. Newly discovered entities such as difhise mterstellar clouds, dense (or dark) molecular clouds and giant molecular cloud complexes were characterized for the first time. Indeed, radioastronomy (which includes observations ranging from radio to submillunetre frequencies) has dramatically changed our perception of the composition of the universe. Radioastronomy has shown that most of the mass in the interstellar medium is contained in so-called dense... 

Let us define knowledge as the perception of the logical relations among the structures of the information. One thing we have to bear in mind is that any systematic treatment of information needs some previous knowledge. Therefore, research, in the long run, is always an iterative process, as depicted on Figure 4-1. 

As time passed, the balance of Stacey s interests changed He became less involved with the close direction of research and more with administration. Moreover, his chemical work had become far too wide for him to have a detailed knowledge of all of it. He retained his strategic foresight and, always, could advise how best to develop a project. He had an ability to join forces with and motivate his colleagues, who carried forward the detailed work. Also, he was able to recall, with uncanny accuracy and perception, the ability and character of each of the many collaborators, with whom he had been associated during his career. 

This book attempts to capture some of the best practice in mentoring program design and management, based on research, observation and the experience of companies around the world. It also tries to reflect the diversity of application and perception of mentoring in different environments and cultures.

One reason for the seemingly slow progress of understanding is the interdisciplinary nature of sweetness research. The conclusions that can be drawn, from, for example, physiological and psychophysical experimentation, must be related to what is known of the structural chemistry of the stimulus and how it may interact at the molecular level. All too often, it is not appreciated that one particular line of experimentation cannot be viewed in isolation, but must relate to other disciplines. Only by fully understanding all of the associated events leading to sweetness perception shall we understand the mechanism of sweetness perception itself. 

Understanding quality perception. The starting point of a CQP-based quality assurance system should be the clear understanding of which product attributes are considered important and contribute to the quality perceptions of target consumers. This will help focus the system to control and assure only those attributes that are critical for quality perception. Decision-supporting tools can be found in the areas of consumer research, sensory studies, and new product design. 

The determination and analysis of sensory properties plays an important role in the development of new consumer products. Particularly in the food industry sensory analysis has become an indispensable tool in research, development, marketing and quality control. The discipline of sensory analysis covers a wide spectrum of subjects physiology of sensory perception, psychology of human behaviour, flavour chemistry, physics of emulsion break-up and flavour release, testing methodology, consumer research, statistical data analysis. Not all of these aspects are of direct interest for the chemometrician. In this chapter we will cover a few topics in the analysis of sensory data. General introductory books are e.g. Refs. [1-3].
