I'm trying to define my sections for my research paper using APA guidelines :
Section : Centered, Boldface, Uppercase and Lowercase Headings
Subsection : Left-aligned, Boldface, Uppercase and Lowercase Heading
Subsubsection : Indented, boldface, lowercase heading with a period. Begin body text after the period.
To do so, I am using the following commands :
\makeatletter
\renewcommand*{\addperi}[1]{#1.~}
\renewcommand{\section}{\@startsection {section}{1}{24pt}%
{\parskip}{-\parskip}%
{\centering\normalfont\normalsize\bfseries\addperi}}
\renewcommand{\subsection}{\@startsection{subsection}{2}{24pt}%
{\parskip}{-\parskip}%
{\normalfont\normalsize\bfseries\addperi}}
\renewcommand{\subsubsection}{\@startsection{subsubsection}{3}{24pt}%
{\parskip}%
{-\parskip}%
{\normalfont\normalsize\bfseries\addperi}}
\makeatother
However, my sections, subsections and subsubsections all look the same : the sections are not centered but indented and are followed by a period; the subsections aren't left-aligned but indented, and followed by a period, and my subsubsections look just right. Basically all of my sections look like subsubsections.
The document class is : \documentclass[doc,apacite]{apa6}
apa6
class give the right headings?
