There are two types of visual agnosias- Apperceptive agnosia and Associative agnosia. Apperceptive agnosia is the physiological type of visual agnosia‚ where it is a failure of recognition due to damaged visual perception. Associative agnosia is the developmental type. It is where perceptual ability is intact‚ but

Discuss evolutionary explanations of human aggression One evolutionary explanation of human aggression is sexual jealousy. Infidelity triggers sexual jealousy which is an evolved adaptive response to infidelity. Men have developed many strategies from vigilance to violence to stop their partner committing adultery. Men never know for certain that the baby is theirs and could be investing in another man’s baby. In a questionnaire‚ if women reported that their partner did not like them talking to

Relevant studies of institutional care include Hodges and Tizard‟s longitudinal study of 65. British children from early life to adolescence and Rutter‟s study of Romanian orphans adopted by British families. Earlier research such as Skodak & Skeels or Spitz & Wolf may also be cited.

notes that in every country that has TV‚ it has generated social concern‚ making the public blame the media for any rise in aggressive behaviour in young people. Huesmann and Moise (1996) give five ways that exposure to media violence may lead to aggression. One of these five ways is observational learning and imitation which is linked to the social learning theory that Bandura put forward. Huesmann suggests that children will observe the behaviour of certain role models they may identify with within

Outline key features of the evolutionary perspective explanation of attachment and evaluate. An attachment is an emotional bond between two people. It is a two-way process that endures over time. An evolutionary perspective of attachment was researched by the famous John Bowlby in 1969. Bowlby observed both humans and mammals. Bowlby ’s theory is an evolutionary theory‚ he emphasised that attachment had evolved‚ which means it was not something that was taught‚ because of its survival and reproductive

Outline and Evaluate one or more explanations of why people obey It has been found by Milgram that people obey for four main reasons these are; legitimate authority‚ the momentum of compliance‚ the agentic shift and passivity. The first reason that Milgram found that people obey is because people feel like they have to obey someone if they have a high social status or a highly respected job‚ this is called legitimate authority. Bickman (1974) supported this theory by doing an experiment on the

neural and/or hormonal mechanisms in aggression (8 marks + 16 marks) Aggression is a behavior directed towards another intended to harm or injure. Neurotransmitters are chemicals that enable impulses in the brain to be transmitted from one area of the brain to another. There’s evidence that the neurotransmitters serotonin and dopamine are closely linked to aggressive behavior. Low levels of serotonin and high levels of dopamine have been associated with aggression in both animals and humans. Low levels

Outline and evaluate restoration explanations for the functions of sleep [8 + 16] intro: Aleep is divided into several different stages. SWS and REM sleep are associated with particular benefits. Oswald (1980) proposed that each of these had different functions - slow wave sleep enables body repair and REM enables brain recovery. SWS – initiates body repair (Oswald) Growth hormone – important in childhood because it stimulates physical growth. Important throughout lifespan for protein synthesis

Outline and evaluate research into types of attachment. Ainsworth conducted a study to observe types of attachment behaviours with occur between a mother and a child. She used observation to witness these behaviours. By placing the child in a set up play room with one way glass allowed natural behaviour to be observed without interference from the psychologist. Ainsworth used several situations including a mother a child and a stranger. Firstly the mother and the child entered the room‚ the child

Outline and Evaluate Evolutionary Explanations for Human Aggression. (25 Marks) . The high incidence of aggressive behaviour across cultures and through time has led evolutionary psychologist to conclude that the adaptive and functional benefits of aggressive behaviour must outweigh the possible costs (Buss and Duntley‚ 2006). From an evolutionary perspective humans are most likely to survive if they have access to resources (food‚ water and territory); if they can defend their resources and
