However, the investigator is not guilty of interfering, though his or her presence may have some unwanted effects. EX POST FACT0 RESEARCH Very many studies reported in the psychological journals are those in which existing differences are sought between groups of people and no IV is manipulated by the researcher. As we saw in Chapter 1, it is legitimate to hold a theory, produce hypotheses from it and to check these out by measurement. The Rutter (1971) and Penny and Robinson (1986) studies mentioned there were examples.

This difference is explained further below. In an experiment where the same people are in each condition ('repeated measures' - see next chapter) the variable of differences-between-groups is completely controlled by elimination. INVESTIGATIONS W H I C H ARE N O T EXPERIMENTS In contrast with the exveriment, consider the studv of the effect of earlv visual stimulation on children's later cognitive development. We can't take a group of children and deprive them of visual experience under controlled conditions.

But in psychology it is of crucial importance not to claim you've discovered or demonstrated something which you haven't. Consider the common psychology class practical where we devise a questionnaire concerning say, homosexuality. This is discussed as the measurement of an 'attitude'. However, almost all definitions of 'attitude' include something about an enduring belief - yet we've only measured a person's view at one moment. Will they think this next week? What have we measured exactly? In any case, does our questionnaire tap anything like the full range and depth of an 'attitude to homosexuality'?
