Outline and evaluate neural and hormona essay outline and evaluate neural and hormonal mechanisms in aggression there are two main biological explanations to aggression, neural and hormonal. outline and evaluate biological explanations of obesity various explanations can be provided for the reasons of obesity, from biological explanations, to neurological and evolutionary theories. An endocrine gland may also secrete a hormone in response to the presence of another hormone produced by a different endocrine gland such hormonal stimuli often involve the hypothalamus, which produces releasing and inhibiting hormones that control the secretion of a variety of pituitary hormones.
Testosterone is a male hormone (androgen) produced mainly in the testes in men and in the adrenal cortex in women its level rises sharply in males at puberty and has masculinising effects it is believed that there is a link between high levels of testosterone and high aggressive behaviour. Psychology 8 ed, david myers module 4 powerpoint slides, aneeq ahmad 2 4 neural and hormonal systems the endocrine system outline the effects of acetylcholine. Describe and evaluate how neural and hormonal mechanisms influence aggressive behaviour (24 marks) neurotransmitters are chemicals that allow impulses within the brain to be transmitted from one area of the brain to another. 2 hormones chemicals that are broadcast throughout the body which induce physiological changes in specific target cells hormone classes • amines - hormones derived from tyrosine and.
Neural & hormonal mechanisms - student handout (part 2) imagine that you are writing the outline to the following question: outline and evaluate the role of neural mechanisms in controlling eating. Outline and evaluate two or more theories of the formation of romantic relationships (8+16 marks) discuss one theory of the formation of relationships (8+16 marks) outline and evaluate two or more theories of the maintenance of romantic relationships (8+16 marks. Describe and evaluate hormonal mechanisms in aggression (8 marks + 16 marks) for this question you should discuss the roles of both testosterone and cortisol in aggression. Outline and evaluate the role of neural mechanisms in controlling eating behaviour (24 marks) today there is enormous interest in the psychological factors that can affects a person's eating habits, but some of the clearest research findings have come from research into the brain (neural) mechanisms controlling eating behaviour.
Outline and evaluate neural and/or hormonal mechanisms in aggression (8 and 16 marks) the hormone testosterone is believed to influence aggression due to its action. What is the role of serotonin in causing aggression - evaluate studies cases 1995- serotonin in normal levels inhibits neuronal firing, low levels particularly in the prefrontal cortex makes individuals less able to control their impulsive and aggressive responses. Outline and evaluate the role of neural mechanisms of controlling eating neural mechanisms are structures that regulate behaviour and voluntary and involuntary bodily functions the main area of the brain involved in the regulation of appetite is the hypothalamus. A lack of serotonin neural transmitter has been linked to increases in aggression serotonin helps us keep us calm and therefore make rational decisions, but with a deficiency, we are less inhibited - less able to process the consequences of aggression, therefore leading to an increase.
Outline and evaluate the role of neural and hormonal mechanisms in aggression [24 marks] neurotransmitters are chemicals that allow impulses from one area of the brain to be transmitted to another area. Ao2 evaluation for hormones as a cause of aggression archer (1991) found a correlation between aggression and testosterone levels book et al (2001) conducted a large meta-analysis of 45 studies and found a weak positive correlation between testosterone levels and aggression. Neural and endocrine regulatory mechanisms work to maintain the optimal conditions in the lumen needed for digestion and absorption these regulatory mechanisms, which stimulate digestive activity through mechanical and chemical activity, are controlled both extrinsically and intrinsically.
With this background, it becomes important to understand the neuro-endocrine regulation of blood pressure (bp) control which is the subject of this review the regulation of bp is a very complex physiologic function, dependent on a continuum of actions of cardiovascular, neural, renal, and endocrine systems. Discuss neural and hormonal mechanisms in aggression (8 marks + 16 marks) you should outline and evaluate the link between aggression and neurotransmitters such as serotonin and dopamine, and hormones such as testosterone and cortisol. The endocrine system is also essential to communication this system utilizes glands located throughout the body, which secrete hormones that regulate a variety of things such as metabolism, digestion, blood pressure and growth.
Evaluation of neural explanations the neurochemical explanations of offending behaviour have been criticised for being overly simplistic the links between abnormal levels of a certain neurotransmitter and offending behaviour, often centre around violent and aggressive behaviour, which does not explain all types of crime. Chemical messengers that cross the synaptic gaps between neurons when released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.
Outline and evaluate neural and hormonal mechanisms in aggression (8 + 16 marks) - biological explanations offer a completely different perspective to the explanation of human aggression. These study notes evaluate the following explanations of aggression: 1) limbic system, 2) neurotransmitters, and 3) hormones kluver and bucy (1939) were early researchers who, using rhesus monkeys, removed the main areas of the limbic system including the amygdala, hippocampus and surrounding cortical areas. Outline and evaluate neural and hormonal mechanisms in aggression there are two main biological explanations to aggression, neural and hormonal the neural explanation is the serotonin and dopamine neurotransmitters and how they affect our aggression the hormonal mechanisms are the testosterone and cortisol chemicals. outline and evaluate sociological views on the role of the family in society (33 marks) there are three main different sociological view points on how sociologists view the family these are functionalist, marxist and feminist views.
