validity

• Validity

  -          When setting validity you can also look at the measures predicted validity this refers to how well a test can predict future events or behaviours for example how childhood attachment found in a strange situation is able to predict how a child will behave when they are an adult
• Validity

  -          when assessing external validity we can also look at the temporal validity within the study and this is the extent to which we can generalise the findings to different time periods and if we are studying something that is universal about behaviours we would expect it to have high temporal validity but for example Asch studies are likely to lack temporal validity as conformity rates were high in the 1950s in the USA
• Validity

  -          when assessing external validity we should also focus on the psychological realism of the study - therefore thinking all the psychological process is being measured the same as which would occur in everyday life and this is what the research is most concerned with
• Validity

  -          when assessing external validity we can also look at the mundane realism of the experiment- so does the experiment mirror the real world and resemble events in normal everyday life
• Validity

  -          when assessing external validity we need to consider the ecological validity of the results this means the extent to which we can generalise the findings to different contexts
• Validity

  -          external validity is concerned with factors outside of the study and to what extent the research findings can be generalised to other situations and people beyond those in the study under cross different time periods
• Validity

  -          another way to assess internal validity is to consider whether the measures of behaviour have concurrent validity which is where the measures in the study I'll compared to the measures in another study which has been previously validated and if a strong correlation between the two is found it would suggest that the new measure has validity
• Validity

  -          to assess internal validity you can consider whether the measure of the behaviour has face validity so does it appear to be measuring what it claims to be – which may involve experts looking at the design measures in a study to see if they are appropriate to the aim of the study for example measuring heads conference to test intelligence has low face validity
• Validity

  -          internal validity - is concerned with what goes on inside a study and whether the researcher did test what they intended to test so in an experiment it refers to whether the research is due to the manipulation of the independent variable and has not been affected by confounding variables like demand characteristics
• Validity

  -          validity is referring to accuracy so the degree to which something measures what it claims to
