Before I summarise the material in this section, and we move on to consider attentional processes with clearly-seen displays, it would be appropriate to consider the relevance of the masking studies to the issue of attention. We began the whole subject by enquiring about the fate of material which was, in principle, available for processing, but happened not to be at the focus of attention. Somehow we have moved into a different enquiry, concerning the fate of material that a participant was

The three levels of change problem, simplicity, complication and complexity, can be associated with craft, engineering and systems engineering knowledge. The three categories of change problem represent different levels of uncertainty of what needs to be done and how to do it. The greater uncertainty brings increased risk. Although we tend to be risk averse we will take on greater risk if the returns are commensurate with doing so.

Human experience can be divided into three worlds. The

One in three people develop cancer, and one in five in Europe and North America die of the disease. Although environmental and lifestyle factors, for example smoking or sun exposure, affect the incidence of some cancer types, all human populations and many types of animal suffer from this di

Ensuring that a user can't choose a wash temperature that's too hot for the â€˜hand washâ€™ programme is an example of ensuring safety. In other words, the washing machine microcomputer is trying to prevent the user making choices that are not sensible. Of course, I could put a load of delicate washing in and choose the â€˜cottonâ€™ programme which has a temperature of 90Â°C. The computer program controlling the machine has no way of knowing that I've put silks or woollens in and not c

In each industrial revolution, new inventions radically changed the way that production and distribution were organised, and often led to large and rapid increases in the efficiency of production. The rise of electricity, for example, allowed US productivity to increase in the manufacturing sector (as opposed to the agricultural or service sector) by more than 5 per cent per annum throughout the 1920s.

Let us pause a moment and consider what this means. The term productivity refe

One important property of DNA is that it carries genetic information in the simple coding language of just four bases. These bases, which can be arranged in a huge variety of sequences, represent a vast potential store of information. In this course, we consider how this information is used by the cell. The key structural feature of complementary base pairs, which plays an important role in both stability and replication, is also the basis for how DNA functions as genetic material.
