Describe the behaviourist approach in psychology and evaluate the research methods used by behaviourist psychologists. The behaviourist approach in psychology states that all behaviour is learnt from experience and from the environment we are in. John Locke (1690) a psychologist described the mind as ‘Tabula Rasa’‚ believing when we are born our minds are completely blank slates‚ and that all of our behaviour is dependent upon our interactions and experiences with the environment.

* Introduction to Organic Chemistry Understand the basis of drawing organic structures Depicting 3-D structures in 2-D Most organic compounds have a three-dimensional structure. How do we represent structures on our two-dimensional page? For example‚ methane is a tetrahedral molecule: Bonds in the plane of the paper: Bonds coming towards the observer: (out of the page) Bonds going away

Environmental Chemistry: Water testing in Bouregreg Valley Nowadays we are more and more concerned of environmental issues and especially the ones about water since experts have remarked that wetland regions are disappearing (50% reduction). Wetland regions are very important because they help preserve different wildlife species and also can be considered important indicators of the health of the “blue planet”. One of the most interesting wetland regions is the Bouregreg one that is close to

Chemistry Coursework – Titration Background Science A titration is the neutralisation of an acid or an alkali. To achieve this‚ one must be added to the other in a specific amount‚ strength and concentration. A substance is neutral when its pH is 7. It is most acidic closer to 0 and is most alkaline closer to 14. 28492453194050 0 7 14 595423979670

The chemistry of hairspray What is hairspray: introduction Hair spray (or hair lacquer) is a common household aqueous solution that is used to keep hair stiff or in a certain style. Weaker than hair gel‚ hair wax‚ or glue‚ it is sprayed to hold styles for a short period of time. Using a pump or aerosol spray nozzle it sprays evenly over the hair. Hairspray was first developed and manufactured in 1948 by Chase Products Company‚ based in Broadview‚ Illinois.Its active ingredient is a suitable

Chemistry in Photography Background A photograph is an image made by a photo-chemical reaction which records the impression of light on a surface coated with silver atoms. The reaction is possible due to the light-sensitive properties of silver halide crystals. Equation form for silver halides: Ag + + e - Ag Species produced include: Ag2+‚ Ag2o‚ Ag3+‚ Ag3o‚ Ag4+‚ Ag4o In 1556‚ the alchemist Fabricius was the first to discover that light can photochemically react with these crystals to

special occasions like independence day. The excitement produced by fireworks like ‚ brightening the night sky and plunging it with vivid displays of colour and insignificant‚ which makes them a crowd pleaser. Behind all the excitement of fireworks‚ chemistry plays an important role in creating the vivid colours we witness lighting up the sky. The actual chemical reactions that take place in the explosions require the use of oxidisers‚ reducing agents and binders. The additions of varying metal chlorides
