The study of physiology no doubt was of major importance in the development of psychology as a science separate from the others. Today, this perspective is mainly known as biological psychology. It is sometimes referred to as biopsychology or physiological psychology. This perspective emphasizes biological and physical bases of behavior.

This perspective observed a significant growth over the last few decades, especially in the light of our advances in the ability to explore and understand the human brain and nervous system. Various tools such as MRI scans and PET scans help the researchers to look at the brain. Scientists can now consider and evaluate the effects of brain damage, drugs, and disease in ways that were next to impossible in the past.

According to Biological psychology, humans a well as animals are born with innate or native behavior and mental structures. This idea proposes that these behaviors and structures need not be acquired through experience, but are native to the body from the start. You must not learn them. You just need not to be taught or felt through the senses.

Biology is defined as "the study of life (from the Greek bios meaning 'life' and logos meaning 'study')”. A biological perspective is referred to the study of Psychology in general three ways:

Comparative method: many different species of animals can be studied and compared. This method can help in the search to understand the concept of human behaviour.

Physiology studies the way how the nervous system and hormones work together, how the brain functions, how changes in structure and function can affect behaviour.

Investigation of inheritance deals with what an animal inherits from its parents. In other words, it studies mechanisms of inheritance (genetics).

Each of these biological aspects can help illuminate human behaviour. If we want to understand all aspects of human behaviour, we should start with one of the smallest units - the cell.

There is a number of different cells in the body, but psychologists are interested in the nerve cell - the neuron. The human brain consists of around 10.000,000,000 neurons. The total collection of nerve cells is called the nervous system, and the major part of the nervous system (the brain and the spinal cord), is the central nervous system (CNS).

Neurons handle information in the body. They take messages from one part of the body to another. There also exists another way of transmitting information in the body - via the endocrine system. The vehicle that transmits information is provided by hormones. They are chemicals carried by the blood from one location to another, more distant location. They take longer to transmit their information than the nervous system, but the effect usually lasts longer.

It is definitely important to Psychology that the nervous system is understood in the following way: the information reaches our CNS and concerns the events both in the outside world and in the internal environment of the body. Everything we feel, do, know has the neural structures of the central nervous system.

If to examine the cell under a microscope, one particular structure is seen central to all cells: the nucleus. The nucleus of every cell in the human body contains 46 structures - chromosomes. They are composed of a complex chemical – DNA. The DNA carries units of information called genes.

Till the 19th c. the dominant view explained the diversity of life on the planet in terms of God's creation. Today the dominant explanatory mechanism refers to the diversity of animal forms is Darwin's theory. The starting point of the theory is that all the physical characteristics of organisms are important for survival and reproducing. All the experiments prove that the animal is more likely to survive in order to reproduce an offspring. Unfortunately only some of the offsprings will flourish. Those animals will flourish at the expense of those without positive characteristic.

All these ideas that can appear to be of biological reference only, has a strong connection with psychology. The genes we have today make us behave the way that we do. They evolved via the process of natural selection. Our brains consist of thousands of millions of neurons. They are responsible for our consciousness, learning, memory, emotion, thought, intelligence, language.

This is the influence and the importance of the biological perspective in modern psychology.

The development of the psychological approach in modern psychology has its own history. The first step of its developmet was the Voyage of the Beagle (1805 - 1836). Charles Darwin formulated his great theory of natural selection due to observing animals while travelling the world. In 1859 Charles Darwin published "On the Origin of Species by Means of Natural Selection". The theory beame very popular as 1,250 copies were printed, and most of them were sold the first day. A little bit later (in 1957) Jane Goodall began her study of primates in Africa. She discovered that chimps possess the similar behaviours to all the human cultures on the planet. Almost thirty years later in 1975 Edward Wilson published his book "Sociobiology". It combined together evolutionary perspective to the psychology. But the very birth of Evolutionary Psychology begins with the publication of by Tooby and Cosmides. It was called "The Psychological Foundations of Culture".

The key concepts of the biological approach include:

· Natural Selection / Evolution

· Nomothetic (studies the group)

The methodology of the method presupposes:

Using the Biological Approach to Explain Lottery Addiction in Children

Using the Biological Approach to Explain Lottery Addiction in Children

Britain is producing a generation of child gamblers hooked on the Lottery and
fruit machines. Disturbing research by two eminent academics shows
that hundreds of thousands of children-some as young as 11- are now
addicted despite the supposed legal restrictions. The findings will fuel
warnings from lottery critics that the country is storing up social problems and
is likely to trigger pressure for a uniform age limit of 18 on all gambling."
(Reproduced from AQA A specimen material.)

In the A level examination you will be required to explain a target behaviour
using any approach. The aim of this activity is to offer you, the candidate, the
opportunity to express your true understanding of the approach by your ability
to use it in a novel situation.

How would you explain lottery addiction in terms of the biological
approach? The currency of the biological explanation is brain activity or
brain anatomy, nervous impulses and neurotransmitters, hormones, and
various organs in the body. A possible explanation could be as follows:

Why are young people hooked on the lottery and fruit machines? A
psychologist might use the biological approach to explain this
behaviour. Such a psychologist would explain the behaviour in
terms of brain activity and the action of the central and autonomic
nervous systems. The psychologist might also mention hormones.
An answer like this would attract relatively few marks as it does little
more than sketch out the possible elements of a biological explanation
and has not demonstrated a true understanding of the approach. In
order to do this you really need to try to put together an explanation of
the target behaviour.

An explanation of lottery addiction using the biological approach
would focus on how biological systems can be used to explain and
understand this behaviour. When an individual stands in front of a
fruit machine the flashing lights are physiologically arousing,
creating a sense of excitement and probably pleasure. Physiological
arousal causes the body to produce certain hormones that prepare
the person for fight or flight. We can also understand the
individual's behaviour in terms of nervous impulses. The eyes watch
the pictures on the fruit machine go round and send impulses to
the brain where they are interpreted and further messages sent to
the hands to press a button at an appropriate moment to stop the
In the A level examination you will be given an opportunity to evaluate
one of your explanations so you can take the opportunity, as below, to
indicate in what way the explanation offered in the first part of the
question is lacking. This highlights the fact that your explanations may
not be satisfactory! They simply need to demonstrate your understanding
of the named approach.

The problem with the biological approach is that for many aspects
of behaviour it ignores some of the key elements of behaviour. In
this case it is largely a description of what is happening at the level
of nerves and hormones and doesn't actually explain anything, for
example why the individual is playing the fruit machine or why the
individual wants to repeat the behaviour. The behaviourist
approach would offer a better account because we can use the
idea of reinforcement and partial rewards.
A suitable methodology for the biological approach
In the examination you will be further asked to analyse how one
approach might investigate this phenomenon, and evaluate the use of
this method of investigating this phenomenon. As already mentioned the
biological approach lends itself to laboratory experiments. Therefore a
further response would be to analyse the use of this method. The process
of analysis involves identifying the constituent parts of a problem and
discussing them. A good student answer might be:

The biological approach is particularly suitable for experiments
because it reduces behaviours to simple components. If we were to
conduct an experiment into gambling behaviour we might assess
the stress experienced by individuals when playing the fruit machine
by using a galvanic skin response. This registers the amount of sweat
being produced during an activity and thus is indicative of
autonomic arousal because when one is in a state of physiological
arousal sweating increases. There are other signs of ANS arousal as
well, such as pupil dilation. We might also consider reaction time
and see whether this was enhanced during high ANS arousal.

The investigation described above could be conducted in a
laboratory where conditions are more highly controlled. Or it might
be conducted in the field where behaviour might be more
naturalistic but, on the negative side, participants' behaviour might
be affected by other things in the environment rather than just the
fruit machine activity (for example a noisy atmosphere in the pub).
Field experiments increase ecological validity at a loss of internal.

Personality can be defined as the complex of all attributes possessed by an individual and that uniquely defines his behavioral temperamental. emotional and mental characteristic from other people Personality has been studied and explained from various theoretical perspectives. Some of these perspectives are. psychoanalytic theories behaviorist theories. trait theories. cognitive theories. humanistic theories and biological theories. This seeks to compare and contrast the biological and humanistic perspectives of personality

br development. The focus will be on the major theorists and key points of both perspectives of personality

The proponents of humanistic theory were Abraham Maslow and Carl Rogers. This theory focuses on the potential of individuals and emphasizes the essence of growth and self actualization. The basic belief of humanistic theory is that people are naturally good with social and mental problems resulting from diverge from his natural tendency. They have emphasized that individual have control in determining their mental health. The theory also credits the environmental influences into account. This theory has continued to influence therapy. healthcare and education. It has helped remove some stigma in therapy and has influenced individual to explore their potential. Though it has been this significant in personality assessment. it does not objectively study and measure humanistic phenomena. It does not give satisfying. For example. in describing self actualization which is a state of self fulfillment. we cannot tell objectively if some one is self actualized.

Reductionist approach – reducing complex assumptions into simple components such as biological make up/processes.

Considers nature rather than nurture.

Assumes that all psychology has a root in physiological make up (ie brain, nervous system, genes, neurochemistry.

Behaviour has a genetic basis – passed on from parents or evolution.

To find out why human behaviour has evolved in the way it has. Evolutionary theory major part of biological approach.

Gender development – genetic and hormonal predispositions
Aggression – testosterone
Abnormality – dopamine/serotonin
Memory – brain damage
Language – Chomsky (origins of language development)

Research the work and application of one of the following biological psychologists:

1. Karl Lashley
2. David Buss
3. Noam Chomsky
4. Pierre Broca
5. Roger Sperry
6. John Money

Objective approach – analytical, not emotional, no bias. Should not know participants.
Scientific – can be replicable, experiments repeated to give same results with the same criteria. (Humans do not behave the same way all the time, are not chemical reactions)
Held under lab conditions so can control conditions and variables eg environment.
Nomothetic approach – establish general patterns of behaviour that can be extended to the population i.e. 1 in 10 extended to 10 in 100. Percentages received applied over population. Experiments generally need over 100 people for validity.
Uses animals – believe motivation is the same, what applies to a chimp will be thought to apply the same way to humans. Results are extrapolated. Humans do not always behave the same way as animals.

Scientific/objective, more credible.
Counter argument to nurture
Effective in treating mental disorders. Schizophrenia/bi polar disease – biological approach gives very good results with appropriate drugs due to.

Thus, the nervous system acts like the information highway of the body in the sense that it receives all information pertaining to regulation of the body, and it also sends out impulses which aid our actions, coordination and homeostasis. The nervous system is composed of two main principal types of nerve cells: neurons and neuroglia. Neurons function in initiation and conduction of impulses whereas neuroglia function primarily as connecting

Yet these two types are not alone responsible for all messages sent throughout the body. Small spaces, known as synapses, are often found between neurons, cell bodies or other receptors.

In order for the body to prepare to defend for itself, blood flow increases to muscles, and a person will experience an increased heart rate, elevated blood pressure, and a slowing of internal functions such as digestion. Once the period of stress is over, the para-sympathetic system acts to restore the body to its normal homeostasis: the heart rate slows, blood pressure reduces and the body will

restart digestion. Therefore, while the two systems oppose each other, they work together to ensure the body's ability to survive. The Brain The brain is one of the largest organs of the body and is the most complex in terms of its responsibilities and functions. It helps to coordinate our body's physical activities as well as store our memories, emotions and consciousness. To continue with the biological approach, this section will first discuss brain size, and then

will focus on five specific areas of the brain that deal with the body's ability to decipher stimuli: the Cerebrum, the Cerebellum, the Diencephalon, the Brain Stem and the Corpus Callosum. Comparatively humans have large brains in respect to other mammals. Though brain's vary in size, the average weight of a mature male is 49+ ounces (or 1424 grammes) whereas a female brain weighs 44 ounces (or 1272 grammes). When compared to an elephant which weighs many

tons, a human brain is approximately the weight of an elephant: 3 pounds for a human versus 8-10 pounds for an elephant. A 75 foot whale will usually have a 5 pound brain despite its massive size. Thus, considering the relative size of the human body, our brain's our relatively large. During its development, a brain will experience different growth rates. Most of its expansion will occur by the time a child reaches seven years

of age. Different stages of growth thereafter occur, but at a much slower pace. There is no set time scale, but around age 16 and then again at 20 growth notably continues to slow down. Between the ages of 30 and 40, growth eventually slows until the brain has reached its maximum size, after which it gradually starts to decrease in size. As aging continues, the brain tends to lose about an ounce every ten years

directly causes complications in a person's memory abilities. This aging process is applicable to both sexes. The Cerebrum is the largest and uppermost part of the brain. It has two hemispheres, a right and a left hemisphere, that are divided by a long groove. The Corpus Callosum' (to be mentioned later) join these two hemispheres and allows information to pass between them. It is involved with the emotional aspects of behaviour and memory although its

major functions are control over muscular movement as well as sensory perception and interpretation. As diagram 2 shows, many voluntary functions are controlled by various Raph (or folds in the outer layers of the Cerebrum). The second largest part of the brain is the Cerebellum which main function is to make the body mobile. It is located in the lower back part of the head (or posterior), just below the Cerebrum. All of its functions are
