    Internal validity- When dealing with this type of validity, you want to ask yourself 'How true are the findings from within the study'. For example, in a study, the behaviour shown by participants may of been due to demand characteristics.This makes us question the extent of how far their behaviour is the result of the independent variable. Thus, the study lacks internal validity.

    External validity- When dealing with this type of validity, you want to ask yourself 'How far can these findings be generalised from beyond the study'. For example, a study may have focused on college students. As these students all share similar ages, it would be hard to generalise to other age groups and due to this, this study will lack external validity.

    Ecological validity- When dealing with this type of validity, you want to ask yourself 'How far can such findings be applicable to real life everyday situations'. For example, a study have a used memory tasks when examining the the duration of the short term store. As memory tasks are not often encountered in ones everyday life, the study may lack ecological validity due to this.

    These are the 3 main types of validity I can think of.

    From my knowledge all specs require you to just know this one type of internal validity.
