Describe the physiological approach to the study of the mind. Explain how Donders experiment can be repeated in a modern laboratory using the physiological approach to the study of the mind Donder’s work attempts to describe the processes going on in the mind‚ by analyzing cognitive activity into separate stages. Until Donder’s work‚ many scientists had assumed that the mental operations involved in responding to a stimulus occurred instantaneously. Donder was particularly interested in "timing

hand warmers‚ mainly the iron powder and activated charcoal‚ and oxygen in the atmosphere‚ react with each other chemically to create warmth. Inside the pouch‚ there is iron powder. When it comes in contact with oxygen‚ the iron rusts and releases heat. The outside bag is a microporous pouch‚ which has tiny holes that are big enough to allow air inside‚ providing the oxygen for the reaction between iron and oxygen. Inside the hand warmer‚ there is also activated charcoal‚ which is charcoal that has been

form an amide. This reaction is widely used‚ especially in the synthesis of peptides. On the simple addition of an amine to a carboxylic acid‚ a salt of the organic acid and base is obtained. To overcome this‚ the carboxylic acid first needs to be "activated". This is usually done by converting the acid into a more reactive derivative (i.e. anhydride‚ acid halide) or by using a coupling agent. In some cases‚ high temperatures (>200 °C) can overcome salt formation by driving off water‚ without the need

others. Mysticism aside‚ the study of blood clotting and the development of laboratory tests for blood clotting abnormalities are historically inseparable. The workhorse tests of the modern coagulation laboratory‚ the prothrombin time (PT) and the activated partial thromboplastin time (aPTT)‚ are the basis for the published extrinsic and intrinsic coagulation pathways‚ even though it is now known that these pathways do not accurately reflect the function of blood clotting in a living organism.

cusps of deep veins. Immobility delays emptying of muscular veins and retards clearance of activated clotting factors. With stasis‚ endothelial cells lining the avascular valve cusps are activated by hypoxemia‚ a process exacerbated by inflammatory cytokines generated postoperatively or in medical illness. Leukocytes tethered to activated endothelial cells express tissue factor‚ whereas platelets become activated and aggregate. Congenital or acquired disorders associated with hypercoagulability promote

A program is always divided into sets of tasks that have to be regularly activated. The pattern of the activation is stored in a table which has rules with schedule of when to run a certain tasks.
