Question
For each of the following studies, cite the likely null hypothesis and the likely research hypothesis.
A.) A forensic cognitive psychologist wondered whether repetition of false information (versus no repetition) would increase the tendency to develop false memories, on average. B.) A clinical psychologist studied whether ongoing structured assessment of the therapy process (versus no assessment) would lead to better outcomes, on average, among outpatient therapy clients with depression.

Explanation / Answer
(A) H0: Null hypothesis: Tendency to develop false memories with repetition of false information = Tendency to develop false memories without repetition of false information
HA: Research hypothesis: Tendency to develop false memories with repetition of false information > Tendency to develop false memories without repetition of false information
(B) H0: Null hypothesis: Outcome of Ongoing structured assessment of the therapy among outpatient therapy clients with depression = Outcome of No assessment of the therapy among outpatient therapy clients with depression
HA: Reaserch hypothesis: Outcome of Ongoing structured assessment of the therapy among outpatient therapy clients with depression > Outcome of No assessment of the therapy among outpatient therapy clients with depression
(C) H0: Null hypothesis: Effects of cubical on employee morale = Effects of enclosed offices on employee morale
HA: Research hypothesis: Effects of cubical on employee morale > Effects of enclosed offices on employee morale
(D) H0: Null hypothesis: Children's ability to speak their native language with teacher a second language to children froom birth = Children's ability to speak their native language without teacher a second language to children froom birth ,
HA: Research hypothesis: Children's ability to speak their native language with teacher a second language to children froom birth < Children's ability to speak their native language without teacher a second language to children froom birth.
