Discuss the multi-store model of memory (12 Marks) The multi-store model of memory was suggested by Atkinson and Shiffrin, in order to explain how memory works. Memory is a system which is vital to our survival. For psychologists, memory covers processes called; encoding, storage and retrieval. Atkinson and Shiffrin (1968) suggested that memory is made up of a series of stores. The stores differ in their encoding, storage and retrieval characteristics. Atkinson’s and Shiffrin’s multi-store model of memory contained three key parts to the memory which were the sensory information system, the short-term memory and the long-term memory. The sensory information system (SIS) was believed to be the storage for memory held as a sensation, e.g. a visual image. Sperling (1960) believed in the SIS and to demonstrate its existence he conducted an experiment. He showed participants three rows of four mixed numbers and consonants for a very brief time, then played them a tone (high, medium or low) to prompt them to recall the top, middle or bottom line. Participants could do this easily if they recalled immediately but the image faded rapidly, lasting for no longer than one-quarter of a second. In this way, Sperling was also able to show that the SIS holds 5-9 items. It also showed that the information was quickly lost as the sensory image fades. The next stage of Atkinson’s and Shiffrin’s model was the short-term memory (STM). Information selected for further processing passes from the SIS into the STM. IT is believed that the STM holds information in the form of images, sounds or meanings. Information in STM is kept ‘alive’ by rehearsing it. Information in the STM lasts up to 30 seconds and is lost through interference or decay. The final stage of

Impact of Fairtrade on Buyer Behaviour

...increase’ from the Financial Times is because it encourages further analysis of consumer behaviour and aids, understanding many of the concepts and models that are core to consumer behaviour. The article reports that consumers in the UK are increasingly purchasing Fair-trade products, citing a 12% rise in 2011 from 2010. Consumers are more prepared to spend their money to help ensure a better deal for foreign farmers and prevent their exploitation and their very motivation behind this demonstrates many of the core concepts of consumer behaviour. The article provides the background information that the overall market growth for grocery products stood at around 5% and suggests that this market growth isn’t sustainable and also suggests that consumers will continue to increase their purchases of Fair-trade products despite increasing financials hardship amongst UK consumers. The article invites analysis of how consumer’s desire for ethically sourced products is being tapped into by companies and what is motivating the purchase decisions of these consumers. It also offers an insight into the organic food products market, which has seen sales fall year on year for the last 3 years. This essay illustrates how by applying consumer behaviour theory to the facts reported in the article, understanding of the consumer is greatly improved. The essay will offer analysis of the consumer from three different perspectives; (1) the cognitive consumer, (2) the emotional consumer and (3) the social...

The Kindle Fire is poised to nibble at Apple’s market share. But this low-cost and under-powered tablet is more likely to suffocate its Android-based brethren than the iPad and actually should cement Apple’s dominance of the general-purpose tablet market. On the plus side, the Kindle Fire has a custom Amazon user interface that supports tight integration with Amazon’s content and media apps. It also includes one month’s free subscription to Amazon Prime (a $6.58 value!), which includes free 2-day shipping and some free streaming video access. In short, at $199, the Kindle Fire is an attractive Amazon shopping and content consumption device. But, in comparison with the iPad, the Kindle Fire has a 33 percent smaller display, no cameras, no 3G wireless, less memory and only two-finger multi-touch (thus limiting its gaming capabilities). As a result, the Kindle Fire will be in direct competition with Barnes...

Introduction to Pyschology

...consists of fifteen words and fifteen pictures were given to the participants to review for two minutes and another two minutes were given to write down as many as they could remember. The mean, median and model numbers recalled pointed that the subjects were extremely good at remembering the pictures if objects accompanied with the pictures compare to if objects accompanied as words. The result used in analysing the difference between two sets of data has proved that there is a difference between subjects’ ability to remember more pictures compare to the amount words. For this reason, the hypothesis was accepted which can be concluded that there is a difference between pictures and numbers of words recalled by the participants. Introduction The major study of memory within psychology is known as cognitive psychology. Generally, the cognitive approach believes that information received from the senses (touch, taste, smell, sight) is developed by the brain and this development might have an effect on how people behave. Cognitive processes are examples of hypothetical constructs which means humans are unable to see processes such as thinking but a person thinking it is likely to be assumed based on how they act.

Cmps 111 Critical Thinking Tablet Comparison

...I am doing my essay on tablets. Tablets, for the most part, have taken over the laptop market. They are light, extremely portable, and can do most everyday laptop functions. The three devices I will be reviewing and comparing are the IPad Air from Apple, the Galaxy Tab S from Samsung and the Surface Pro 3 Windows Tab from Microsoft. These three tablets are some of the best in their class. I chose these three since they run on three different operating systems. The IPad Air runs on the iOS 7.1.1. The Galaxy tab runs on the Android 4.4 KitKat OS. And the Surface Pro3 on the Microsoft Windows 8.1 OS. AS far as which is better, that really is a matter of preference to the user. Depending on what the tablet will be used for will really matter on what system is right for you. I use my tablet for internet use, mobile entertainment and as a better option for a laptop while traveling. I need my tablet to be light, easy to use and capable of doing basic document creation. Cost is a big factor. I already own a couple laptops so this tablet is really a luxury item for me. I use it as a convenient alternative to a laptop while traveling. The Surface Pro 3 is a bit too large and bulky and while ideal for document creation it lacks in the app availability of the other two tablets. While I like the keyboard that the Surface pro offers, it is an additional $130 dollars. It is already almost three times the price of the other two tablets. The Surface Pro simply out prices...
