"Attempts to define abnormality are always limited by cultural differences" Consider how definitions of abnormality may be influenced by cultural differences Cultural differences are always a problem when defining abnormality. What one would consider completely normal in one culture would be considered abnormal in another, for example the island of Java often set fire to a ball soaked in petrol and then play football with it. Here that would be considered wrong and abnormal but is an everyday occurrence for the people of Java. This concept doesn't only apply to eastern cultures; the English could be defined as abnormal by other cultures definitions, even by other western societies e.g. it would not be considered normal by the Italians to wait at a red light when there are no other cars around as the British often do. The 'Deviation from Social Norms' definition of abnormality is greatly limited by cultural differences, for example in Japan there is a very strong work ethic. Those who do not wish to conform and work hard are labelled insane and confined in asylums. If such behaviour was displayed in England they would not be considered insane, they are only treated in such a way in Japan because they have deviated from that cultures social norm. When using this approach to define abnormality you would first have to consider what is normal behaviour for that particular
Outline the clinical characteristics of one anxiety disorder
Outline the clinical characteristics of one anxiety disorder (10 Marks) Anxiety is an adaptive response, an individual with an anxiety disorder experiences anxiety that is disproportionate to threats that are presented. Phobias are the most common form of anxiety disorders. Phobias are an extreme irrational fear of certain situations, objects, people or activities; the level of fear is so great the object or situation is avoided whenever possible. Phobias are classified into three categories, specific phobia, social phobia and agoraphobia. Agoraphobia and social phobia usually interfere with the individuals' daily life, whereas specific phobia generally has less impact. Specific phobias are a fear of specific objects such as animals, the environment, a situation or blood and guts. The prevalence is 4-7% of the population. Specific phobias can be caused from direct experience, observation or from being told to fear the object. The clinical characteristic for this is for the individual with the phobia to avoid the feared object. The anxiety from the situation often results in restlessness, jumpy behaviour; in general the individual finds it difficult to relax and may experience a startled response when presented with the feared stimuli. Social phobias are due to the individual's self-consciousness of their behaviour and a fear of being negatively judged by others in social
Freuds Psychosexual Stages of Development
Freud's Psychosexual Stages of Development Freud advanced a theory of personality development that centred on the effects of the sexual pleasure drive on the individual consciousness. The following five stages are based around the notion that with each stage, the child's libido becomes centred around certain erogenous zones. The Oral Stage The oral stage begins at birth, when the oral cavity is the primary focus of libidal energy. The child, of course, preoccupies himself with nursing, with the pleasure of sucking and accepting things into the mouth. The oral character who is frustrated at this stage, whose mother refused to nurse him on demand or who truncated nursing sessions early, is characterized by pessimism, envy, suspicion and sarcasm. The overindulged oral character, whose nursing urges were always and often excessively satisfied, is optimistic, gullible, and is full of admiration for others around him. The stage finishes at the weaning stage. The stage lasts approximately one and one-half years. The Anal Stage At one and one-half years, the child enters the anal stage. With the advent of toilet training comes the child's obsession with the erogenous zone of the anus and with the retention or expulsion of the faeces. This represents a classic conflict between the id, which derives pleasure from expulsion of bodily wastes, and the ego and superego, which
Neural mechanisms of eating behaviour
Outline and evaluate the role of neural mechanisms involved in the controlling of eating and satiation Our diet is essential to the maintenance of a constant internal environment- or homeostasis. One of the most obvious signs of homeostasis is that humans need to regulate their body weight within very narrow limits; so in order to do this people have to regulate their eating behaviour and food intake. Psychologists have undergone a lot of research into how we regulate eating behaviour. Early studies have shown that lesions to the Lateral Hypothalamus (LH) resulted in aphagia- failure to eat when hungry. Further evidence such as electrical stimulation of this particular area of the brain has lead researchers to believe that the LH acts as feeding centre in eating behaviour. Ranson et al found that a lesion in the VMH of rats would result in overeating and obesity. They concluded that the VMH was a satiety centre in the brain, its role to inhibit feeding behaviour. This research lead to the formation of the dual centre model of feeding: The first stage in eating behaviour is often characterised by feelings of hunger which prompts feeding to start. It has been suggested that the hormone Ghrelin is a key component in the feeding process and researchers say that increased ghrelin production may result in feelings of hunger. Cummings et al investigated the changes in blood
Describe what psychologists have learned about environmental disaster and/or technological catastrophe.
Essay on environmental disaster and catastrophe a) Describe what psychologists have learned about environmental disaster and/or technological catastrophe An environmental disaster is a natural disaster that few people will experience in their lifetime. These are relatively infrequent natural events that are the product of natural physical forces governing the earth and atmosphere. A technological catastrophe is a human made disaster, the result of some human error or miscalculation. These events are usually called disasters when there is a substantial degree of destruction and disruption and the events are uncontrollable either because they are natural disasters or because they represent the occasional loss of control over something which humans normally control very well. Psychologists have studied disasters and catastrophes in an attempt to ascertain what characterises a disaster and what the psychological effects of disaster and catastrophe. It has been found that the characteristics of a disaster effect how people react. One important characteristic is the amount of warning available. Fritz & Marks (1954) found that a lack of warning about a disaster can make the consequences worse, however Drabek & Stephenson (1971) found that the effectiveness of repeated warnings of flash floods was undermined by factors such as families being separated at the time of warnings
Outline and evaluate research into obedience (12)
Outline and evaluate research into obedience (12) In Milgram's original obedience to authority study, his aims were to set up a situation in which single individuals were ordered to act against a stranger in an inhumane way and to see at what point they would refuse to obey the order. Milgram advertised for male volunteers by placing an advert in a local paper, which offered $4.50 as payment for taking part in a study of 'punishment and learning'. 40 respondents from a range of backgrounds were selected and were told to attend the laboratory in Yale University. They were greeted by the experimenter, and were introduced to a 'supposedly' participant, Mr Wallace, but actually he was a confederate. They were both experienced to a role-assignment but it was rigged so that the real participant was the teacher. The experimenter explained to the teacher that it was his job to teach the learner a series of word pairs and then test their recall. If an error was made in the answer, an electric shock was made, starting from 15V working upwards each time. As the shocks became higher, the learner screamed and became more dramatic, and complained of a weak heart at around 180V. The participants showed signs of extreme tension, even showing nervous laughing fits, but they were still told to 'please go on' even though they didn't want to continue. Along side that, when the teacher refused
Describe and evaluate psychological research into conformity and obedience in humans, and consider ways in which this research can be applied to real life.
Joleen Moret 25th November 2002 Access to H.E. Psychology Coursework Describe and evaluate psychological research into conformity and obedience in humans, and consider ways in which this research can be applied to real life. Conformity is a change in behaviour or beliefs as a result of real or imagined group pressure; the feeling that others are putting pressure on us to change our beliefs or behaviour. Asch (1956) compiled a study to see how many subjects would conform and give an incorrect answer to a simple unambiguous task. Apart from one naïve participant, all other members of the group were confederates of the experimenter. The group were sat around a table and asked what line (with a choice of three) matches the single line in a box. The lines were easy to distinguish and if tested on their own, observers made few if any errors. The confederates were instructed to give the same wrong unanimous answer to see if the naïve participant would conform. Thirty-two percent conformed to the group's answer, and seventy-four percent conformed once; thus denying the evidence of their own eyes, giving the wrong answer when it was their turn. During post-experimental interviews with his participants, Asch found that conformity occurred at three levels. Few conforming participants experienced distortion of perception, most conforming participants experienced a distortion
Outline the development of attachments
Developmental Psychology - Key Assessment Task a) Outline the development of attachments An attachment is a powerful bond between an infant and its caregiver. Infants form attachments because they are helpless at birth and so need caregivers to provide for and protect them. There are many long term effects of attachments, for example an attachment gives a foundation for emotional relationships e.g. the infant is learning how to form an emotional or "love" relationship. Schaffer and Emerson believed that infants form attachments by three stages, this argument was based on a large scale study of 60 infants in a working class area of Glasgow over 2 years. The first stage of attachment Schaffer and Emerson believed a child to go through happens when they are 0-6 weeks old, this is known as the Asocial Stage and involves the infant smiling and crying but not directing these emotions at individuals. The second stage of attachment is known as Indiscriminate Attachment and happens when the infant is 6 weeks to 7 months old; this involves the child seeking attention from different individuals. The last stage of attachment is Specific Attachments and happens when the infant is 7-11 months old, this stage shows a strong attachment to one individual, with good attachment to others following afterwards. b) Describe the procedures and findings of one study of individual difference in
Describe and evaluate the recovery/restoration theory of the function of sleep.
Psychology Essay Describe and evaluate one theory of the function of sleep (24 marks) Recovery/ Restoration is one theory on the functions of sleep. This theory is based on the concept that sleep is needed to save energy and to allow restoration of tissue. Research evidence that supports this theory focuses mostly around physiological benefits of sleep. Alison and Cicchetti (1976) surveyed 39 mammalian species to work out the amount of time spent in slow wave sleep (SWS) and in REM sleep. It was found that body weight (which correlates with metabolic rate) was the best indicator of the amount of SWS needed. Oswald's (1980) findings can relate to this; he found that during SWS growth hormones are released from the pituitary gland, stimulating protein synthesis; which is essential for tissue repair. This can explain why new-borns spend a great deal of time sleeping, due to the fact that REM sleep reflects brain recovery and the few months before and after birth are times of rapid brain growth- babies spend 50-60% of their 'sleep time' in REM sleep. Shapiro et al (1981) studied runners who had taken part in an ultra-marathon. They found that the runners slept for around an hour and a half longer than usual for two nights after the marathon. Also, there was an increase in the amount of time spent in SWS. However, this would suggest that people who do little physical activity
Outline and evaluate two social psychological theories of aggression
Outline and evaluate two social psychological theories of aggression. (24 marks) Bandura believed that the potential for aggression may be biological, but the expression of aggression is learned. The social-learning theory (SLT) states that learning occurs through observation of a model. Imitation of an observed behaviour is more likely if the model is someone we aspire to or identify with or if they are rewarded. This is vicarious reinforcement. A child forms a mental representation of an event, including the possible rewards or punishments of the behaviour. When a child imitates an aggressive behaviour, they gain direct experience, and the outcome of the behaviour influences the value of aggression for the child. If they are rewarded they are more likely to repeat the behaviour. Children develop self-efficacy, which is confidence in their ability to successful carry out a behaviour. If aggressive behaviour is unsuccessful for a child, they will have a lower sense of self-efficacy so are less likely to behave this way in future. There is strong empirical evidence to support the SLT. For example, Bandura's Bobo doll studies found that children who observed a model behaving aggressively to the Bobo doll behaved more aggressively than those who observed a non-aggressive model and also imitated specific aggressive acts. This supports the theories claims that behaviour can be
