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 ALERNETHY’S 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.
