Outline and evaluate the evolutionary theory of attachment Bowlby came up with this theory and believed that attachment is innate and adaptive. His theory states that we are born with an inherited need to form an attachment in order to help us survive. This involved Darwins theory of natural selection as any behaviour that helps you survive will be kept in the gene pool. In terms of humans‚ babies are helpless and rely completely on the primary caregiver which is normally the mother. Interestingly

the schizophrenia rather than the cause‚ or linked in ways we have yet to discover. The Dopamine Hypothesis suggests that schizophrenia is associated excess of dopamine or excess of dopamine receptor cells in the brain. Dopamine neurones play a key role in guiding attention so disturbances in this process may lead to the problems of attention and thought found in people with schizophrenia. Neurons are individual nerve fibres that carry electrical/chemical ‘messages’. Many millions are densely packed

Rosenblatt’s Perceptron ORGANIZATION OF THE CHAPTER The perceptron occupies a special place in the historical development of neural networks: It was the first algorithmically described neural network. Its invention by Rosenblatt‚ a psychologist‚ inspired engineers‚ physicists‚ and mathematicians alike to devote their research effort to different aspects of neural networks in the 1960s and the 1970s. Moreover‚ it is truly remarkable to find that the perceptron (in its basic form as described

ARTIFICIAL NEURAL NETWORKS ABSTRACT: “Human Brain‚” the most intelligent device on the Earth‚ is the driving force the ever progressive nature of the Human Species. This is only the reason why _Homo sapien_ has built variety of intelligent devices like supercomputers which can do billions and trillions of calculations each second. But still Human is not able to build a device which can actually mimic its brain. This idea of imitating human brain gave a new area of research known as Artificial

Outline and assess Marxist explanations of crime and deviance. In looking at the Marxist explanation of crime and deviance one must also look to the non-sociologist explanations and those of other different groups in order to come to an informed view of the subject. The non-sociologist definition of crime and deviance would be that deviance is uncommon behaviour‚ something that offends the morals or the majority of society‚ without being harmful or serious enough to be criminal. Whereas

The biological approach to aggression includes the belief that genetic factors play a role in aggressive behaviour and lies within an individual’s genetic make-up. There is supporting evidence of a genetic component of aggression. Psychologists have looked at twin studies to try and find evidence for a genetic basis o compare the degree of similarity of aggression between sets of monozygotic (MZ) twins and dizygotic (DZ) twins. In general it was found that aggressive behaviour is more highly correlated

In 1973‚ Zimbardo carried out an experiment to investigate how readily people would conform to new roles by observing how quickly people would adopt the roles of a guard or prisoner in a simulated prison. Zimbardo took healthy male volunteers and pain them $15 per day to take part in the two-week simulation study of prison life. Volunteers were randomly chosen to be either guards or prisoners. Local police helped “arrest” 9 prisoners at their homes without warning; they were then taken and blindfolded

Control Mechanisms Management with in WellPoint regularly provides updates to the Board regarding performance. Some advantages of bureaucratic control systems are minimal uncertainty about decision making expectation and standards required from staff. Bureaucratic control system has apparent management roles and responsibilities. Disadvantages of this system are lack of employee morale and or room for change and innovation. Stiff procedural guidelines can at times because employees feel disconnected

Outline and evaluate the role of endogenous pacemakers and of exogenous zeitgebers in the control of circadian rhythms (8+16) Circadian rhythms are biological rhythms that occur every 24 hours‚ an example of a circadian rhythm is the sleep-wake cycle‚ another circadian rhythm is body temperature which is at its lowest at around 36 degrees at night and it peaks in the morning at 38 degrees. Endogenous pacemakers are internal body ’clocks’ that will modulate biological rhythms‚ the SCN is an example
