S1 Wk 2 - Falsification, Operationalisation & Testable Hypothesis Flashcards
all these operationalisations are attempts at measuring what
a latent construct
What is empiricism
Knowledge is what can be observed / OR ‘you’ve got to see it to believe it’
psychology is complicated and hard to study
What does operationalise mean
To formalise and define measurement
What is latent construct
Phenomenon that is not directly observed but rather estimated from an operationalised measurement
What does atomise mean
Evaluate parts of the whole (in chemistry and physics literally subatomic behaviour)
An operationalisation over phenomenal should be: 3 points
- Specific
such as not measuring Happiness by measuring
how energetic person feels - tied to a theory / model of behaviour
such as theoretical distinction between anxiety
fear and stress - developed an replicable and clear process
so that anyone could identify how someone
arrived at this measure
Psychology exists because
It is hard to measure our latent constructs
The empiricist Carl Popper suggested that ideas need to be
Falsifiable - the ability of an idea to be able to be demonstrably wrong
Why is being wrong important
Limits the expansiveness of ideas so that a debate / investigation can be held
What is a hypotheses
A prediction about the nature of phenomenon
What is the null hypothesis
There is no notable effect in the investigation. any small effects are due to chance alone
What is the alternative hypothesis
There is an effect of the investigation. these differences are more notable than chance alone
