Personal Pronouns
Personal pronouns (I, my, you, we, etc.) should not be used in psychology papers. Usually, they are superfluous and unnecessary.
Examples
(Note: the following examples were composed to illustrate pronoun use only and are not factual):
Poor: "I agree with Jones and Smith (1995) that Factitious Disorder by Proxy should be included in the next edition of the DSM because it would benefit children by making medical professionals aware of the disorder."
Good: "The results of the Jones and Smith (1995) study imply that including Factitious Disorder by Proxy in the next edition of the DSM would increase awareness of the problem among medical professionals, leading to the protection of children who would otherwise fall victim to this unique form of abuse."
Poor: "Factitious Disorder by Proxy, in my opinion, is not a psychiatric disorder, but a criminal act. It should not be included in the DSM because this would allow child abusers to get away with it."
Good: "As public awareness of Factitious Disorder by Proxy has increased, a number of accused child abusers have claimed to suffer from this disorder in attempts to avoid punishment (Black, 1996; White, 1995; Green, 1997). These data suggest that, if Factitious Disorder by Proxy is deemed to be a mental illness, child abusers may no longer be prosecuted or punished for behaviour that is currently considered to be a crime."
