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

Cognitive experimental research and theory has led to the development of new eyewitness procedures. Evaluate the impact that these developments have had in obtaining more accurate eyewitness evidence. Eyewitness evidence is hugely influential in the conviction of those accused of crimes‚ however multiple factors can manipulate the recall of events witnessed and as such mistakes frequently occur. The techniques for gathering witness evidence have historically lacked a consistent procedural standard

Obedience is when an individual responds to an order from an authority figure. A key study that has looked into research is one carried out by Milgrams in 1963. The aim of the experiment was investigate whether ordinary people will obey a legitimate authority figure even when required to injure an innocent person. Milgrams recruited 40 male participants by advertising for volunteers to take part in his study. Each participant would be paid $4.50. The experiment consisted of one ‘real’ participant

Outline and evaluate The SLT theory of aggression. Aggression is defined by Baron & Richardson (1993) as ‘any form of behaviour directed towards the goal of harming or injuring another living being who is motivated to avoid such treatment’. According to Social Learning Theory aggressive behaviour is developed through the environment (rather than being an innate tendency – as the biological and psychoanalytical theories would suggest). If biological theories of aggression were faultless it

Outline and evaluate biological explanations for aggression (24) The biological explanation for aggression states that aggression is innate behavior in people and the environment around them does not cause it. Neurotransmitters in the brain‚ chemicals that allow impulses to be transmitted from one area to another‚ can be used to explain why some people are aggressive. There is evidence to suggest that the neurotransmitters serotonin and dopamine are linked to aggression‚ low levels of serotonin

Outline and evaluate the biological approach to psychopathology The biological approach to psychopathology suggests that abnormal behaviour is caused or related to physical changes in the body. The biological approach suggest that the four following things cause physical disorders (abnormality) ; genes‚ biochemistry‚ neuroanatomy and viral infection. Psychologists have investigated the role in which gene’s play in abnormal behaviour. To do this the majority of psychologists use twins. It has been

Outline and evaluate research into maternal deprivation. (18 marks) Bowlby’s maternal deprivation hypothesis suggests that bond disruption between the infant and caregiver in the early years can have detrimental and irreversible effects on the intellectual‚ social‚ and emotional development of the child. He carried out the study on 44 juvenile thieves (that were transferred to his institution)‚ whom he compared to a group of 44 controls. It was a retrospective study using interviews and questionnaires

Outline and evaluate psychological explanations of schizophrenia (24 marks) Brown and Birley studied stressful life events in the role of relapse in schizophrenics. They found that 50% of people experience a stressful life event e.g. death‚ relationship break-up‚ job loss etc. in the 3 weeks prior to a schizophrenic episode. A control sample reported a low and unchanging level of stressful life events over the same period. However not all evidence supports the role of life events. For example‚

Outline and evaluate the biological explanation of depression. Biological explanation of depression can be explained by neurotransmitter dysfunction. Neurotransmitters such as noradrenalin and serotonin have been shown to be linked with depression. Bunney at al (1965) found that there was low levels of noradrenaline function in the brain of depressed individuals. Also‚ post mortem studies found increased noradrenaline receptors in the brains of depressed suicide victims. When there is low noradrenaline

Outline and Evaluate strategies for memory improvement. (12 marks) The first main memory improvement technique is the use of verbal mnemonics that focuses around words. For example acronyms‚ (where a word or sentence is formed from the initial letters of other words) e.g. - UNICEF - The United Nations International Children’s Emergency Fund. Another technique is an acrostic (a poem or sentence where the first letter in each line/word forms the method used for the item being remembered). E-g Homework
