AS LEVEL PSYCHOLGY RESEARCH METHODS RESEARCH HYPOTHESIS

AIMS OF THE RESARCH THE AIMS AREBTHE CLEARLY STATED INTENTIONS/ PURPOSE OF THE STUDY ALL STUDIES START WITH AN AIM E.G BADDELEYS INTENTION WAS TO STUDY THE EFFECTS OF CONTEXT ON RECALL. THE AIMS THEN LEAD TO A HYPOTHESIS

HYPOTHESIS THIS IS A CLEAR TESTABLE STATEMENT OF WHAT THE RESEARCHER BELIEVES TO BE TRUE AND ITS WHAT HE AIMS TO DEMONSTRATE IN THE STUDY. A HYPOTHESIS STATES THE EXPECTED RELATIONSHIP BETWEEN THE I.V AND THE D.V.

HYPOTHESIS IN ALERNETHYS ON CONTEXT AND MEMORY RECALL STUDY THE EXPERIMENTAL (ALTERNATIVE) HYPOTHESIS MIGHT BE PARTICIPANTS DO BETTER ON A TEST WHEN TESTED IN THE SAME ROOM WHERE THEY WERE TAUGHT RATHER THAN TESTED IN A DIFFERENT ROOM

HYPOTHESIS THE D.V WAS PERFORMANCE ON THE TEST THE I.V WAS WHERE THE PARTICIPANTS WERE TESTE SAME ROOM ( EXPERIMENTALCONDITION) DIFFERENT ROOM ( CONTROL CONDITION)

DIRECTIONAL HYPOTHESIS A DIRECTIOAL HYPOTHESIS PREDICTS THE OF DIFFERENCE OR RELATIONSHIP BETWEEN GROUPS OF PARTICIPANTS STATES WHICH SET OF SCORES WILL BE BETTER/FASTER IN AN EXPERIMENT POSITIVELY OR NEGATIVELY CORRELATED PRIVIOUS RESEARCH SUGGESTS THE DIRECTION OF THE ALERTNATIVE HYPOTHESIS

NON DIRECTIONAL HYPOTHESIS PROPOSES THAT THERE WILL BE A DIFFERENCE OR RELATIONSHIP BUT DOES NOT STATE THE DIRECTION. ALLOWS FOR A DIFFERENCE/RELATIONSHIP OCCURRING IN EITHER DIRECTION OR PRIVIOUS RESEARCH HAS BEEN INCONCLUSIVE.

NON DIRECTIONAL HYPOTHESIS PARTICIPANTS PERFORM DIFFRENTLY DEPENDING ON WHETHER THEY ARE TESTED IN THE SAME ROOM WHERE THEY WERE TAUGHT RATHER THAN TESTED IN A DIFFERENT ROOM. THIS IS A NON -DIRECTIONAL HYPOTHESIS BECAUSE IT JUST PROPOSES THAT THERE WILL BE A DIFFERENCE BETWEEN THE TWO GROUPS OF PARTICIPANTS

NON DIRECTIONAL HYPOTHESIS A NON DIRECTIONAL HYPOTHESIS PREDICTS SIMPLY THAT THERE WILL BE A DIFFERENCE BETWEEN THE TWO GROUPS OF PARTICIPANTS

THE NULL HYPOTHESIS A STATEMENT OF NO DIFFERENCE OR NO RELATIONSHIP. IT ACTS AS A BASELINE CONCLUSION IN A RESEARCH STUDY.

THE NULL HYPOTHESIS RESEARCHERS STATE THE NULL HYPOTHESIS THERE WILL BE NO DIFFERENCE IN RECALL SCORES BETWEEN PARTICIPANTS TESTED IN THE SAME ROOM WHERE THET WERE TAUGHT AND THOSE TESTED IN A DIFFERENT ROOM TO WHERE THET WERE TAUGHT. THE NULL HYPOTHESIS IS THE ONE WE ARE TESTING IF THE SCORES DO NOT PROVIDE SIGNIFICANT DIFFERENCES THEN WE ACCEPT THE NULL HYPOTHESIS. IF THE DIFFERENCE BETWEEN THE CONDITIONS IS SIGNIFICANT THE NULL HYPOTHESIS CAN BE REJECTED

THE NULL HYPOTHESIS THERE WILL BE NO DIFFERENCE IN STRESS LEVELS (G.S.R) BETWEEN PARTICIPANTS UNDERTAKING A VIGILANCE TASK IN THE NOISE CONDITION AND THOSE IN THE NO NOISE CONDITION.
