Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.
Statement I:The double-blind procedure is an effective solution to the issue of experimenter bias in research.
Statement II:The problem of experimenter bias can also be solved by non-verbal cuing of the participants.
ABoth Statement I and Statement II are true
BBoth Statement I and Statement II are false
CStatement I is true but Statement II is false ✓ Correct
DStatement I is false but Statement II is true
Correct answer: (C) Statement I is true but Statement II is false
Explanation
The double-blind procedure, where neither participant nor experimenter knows the condition, effectively curbs experimenter bias.
Statement 1 is therefore correct.
Statement 2 is false because non-verbal cuing of participants creates rather than solves experimenter bias.
Subtle unintended signals from the researcher steer participants toward the expected response.
Removing the experimenter's knowledge of conditions blocks such cueing at its source.
Rosenthal's studies on the experimenter expectancy effect established this concern.
