The aim of the study was to examine the validity of the matching hypothesis. This theory suggests that we tend to form loving relationships with people perceived as being a similar level of attractiveness to ourselves. Ten heterosexual long term couples aged 18-24 were photographed individually. These pictures were then divided into groups according to their sex and were ranked separately in order of physical attractiveness by 40 independent judges (20 male and 20 female) aged 18-24.

Genetic and environmental factors affecting intelligence

AO1: The genetic approach to explaining performance on intelligence tests has controversially claimed that intelligence may be passed from one generation to another. The main source of evidence for this area has been twin studies which compare the concordance rates for IQ scores for Mz and DZ twins. Another area of research has been looking at family relatedness and concordance rates on intelligence tests. MZ twins are identical twins and have the same genetics as each other so if intelligence…...
A Correlation Between Raptor Abundance And Dune Height
Words • 404
Pages • 2
The results shown in this report demonstrate a strong correlation between raptor abundance and dune height and can therefore infer that it supports the hypothesis being tested. A primary mechanism for why raptors use taller dunes may be for efficient flight patterns. Previous literature has focused on avian scavengers and their physical morphologies, for the adaptation of soaring flight rather than flapping. They utilise strong winds (thermals) in high mountain ranges to aid in soaring patterns (Ruxton & Houston 2004).…...

What is Correlational Research?
Words • 1141
Pages • 5
The correlation research method is appropriate when researchers want to study and “assess relationships among naturally occurring variables.” Assessment means making predictions about the nature of the relationships being studied. It also means describing the relations and assigning them a “correlation coefficient” that describes the direction and magnitude of the movement of variables to one another. There are many types of correlational research. The commonality among all types of correlational research is that they explore relationships between variables. Where descriptive…...

The latter is uncontroversial, given the time and professional and educational experience inmates lose, the difficulties they have finding a job after their release etc. But what about the former statement? Crime obviously has many causes, and poverty is most likely one of them in some cases. It seems likely that some poor people may sometimes have to resort to theft…...

re are several different explanations for the disorder schizophrenia. One of these explanations is the biological model. This model explains schizophrenia through biological faults, for example viral infections and brain abnormalities. Genetic Factors Some psychologists say that schizophrenia can be passed down generations, meaning that some people inherit the disorder from their parents. Twin research has consistently shown that identical twins have a greater risk of developing schizophrenia, if their twin has the disorder, than non-identical twins. Gottesman found monozygotic…...

Correlation Correlations measure the relationship between two variables. Establishing correlations allows researchers to make predictions that increase the knowledge base. Different methods that establish correlations are used in different situations. Each method has advantages and disadvantages that provide researchers information that is used to understand, rank, and visually illustrate how variables are related. The Pearson’s, Spearman, Kendall Rank, and positive and negative correlation are methods used to establish a correlation between variables. The Pearson method is a simple linear correlation…...
