Outline and evaluate research into encoding in memory (8) A study by Baddeley was conducted in 1966. He did two experiments looking into the STM and LTM. In these two studies he gave participants four lists of words. These were a list where the words were acoustically similar another where they were acoustically different and one where they were semantically similar and the last where they were semantically different. They were read the lists and then given an interference task for 20 seconds

Outline and evaluate research into the duration of memory (12 marks) Peterson and Peterson researched into the duration of the STM. They used trigrams and asked their participants to recall them after a retention interval‚ the retention interval was different every time. They found that after 3 seconds participants could recall about 90% correctly but after 18 seconds only 2% could be recalled correctly. Peterson and Peterson concluded that the STM has a limited duration and when rehearsal is

Asch carried out an experiment in 1951 to investigate the extent to which social pressure from a majority group could affect a person to conform. Asch used a lab experiment‚ where 50 male students from a college in the USA participated in a ‘vision test’. Using a line judgement test‚ one of the more naïve participants was put in a room with 7 confederates. The confederates had agreed in advance what their responses would be involving the line task. The real participant didn’t know this‚ and was led

Psychology Outline and evaluate the multi-store model The MSM was created by Atkinson and Shiffrin (1968) who suggested that memory was comprised of three separate stores. They were; sensory memory‚ short term memory and long term memory. The model shows how information is transferred between the three stores. The model simply shows that when your are given information of environmental stimuli it will enter your sensory memory and only if you pay attention will it enter your short term memory‚

Discuss - are the effects of privation reversible? Privation is the failure to form an attachment during the early development stage. If this occurs‚ then there is normally a lack in basic survival needs such as food and comfort. There are many effects of privation‚ due to the lack of attachment forming‚ such as late development and malnourishment. One case of privation was that of Genie who was studied by Curtiss in 1970. Genie was found when she was 13 in 1970. Her father had considered her mentally

Outline and evaluate the ‘WMM’ (12marks) The working memory model (WMM) has four components. The central executive controls and monitors the operation of the other 3 components. It also allocates attention. The phonological loop is sub-divided into 2 smaller components‚ the articulatory control system‚ where information is rehearsed sub vocally or in the inner voice and the phonological store where speech is held for a very brief duration in the inner ear. The third component is the visuo spatial

Outline and Evaluate research into Cultural Variation in attachment If attachment is a biological innate process‚ as Bowlby’s theory suggests‚ then secure attachment should be the best form for all humans regardless of variations in culture. However‚ there is much research against this statement‚ making us question whether attachment is or is not a biological innate process at all. Studies such as Ainsworth’s Uganda research support Bowlby’s theory. She observed how infants in Uganda‚ like in

Outline and Evaluate research into individual differences in attachment Attachment is when you get a strong reciprocal‚ emotional bond between two people like with a mother and infant. The attachment acts as a basis for further emotional and psychological development. Following on from the study carried out by Schaffer and Emerson (1964) on the phases of development in attachment‚ Ainsworth and Bell (1978) investigated individual differences in attachment using the Strange Situation. They hoped

Outline and evaluate research into cultural variations in attachment Due to the fact that the ways that people bring up their children can be very different all over the world as we share different attitudes‚ values and beliefs etc. People emphasize on developing distinct skills and qualities‚ so attachments formed can be different. For instance‚ countries like America and Germany would value personal independence and achievement more‚ whereas interdependence between people is valued more in China

Privation is the failure to form attachment. It occurs when a child has no opportunity to form a relationship with a parental figure‚ or when such relationship is distorted‚ due to their treatment. It is different to deprivation‚ which occurs when an established relationship is severed. It is understood that privation can produce social‚ emotional‚ and intellectual problems for children; however‚ how inevitable such problems become as a results of privation and the extent to which can be reserved
