In an interview with disneydreaming.com, Osment stated that she had begun working on the album in October, and had quickly rushed to finish it. In the interview, she revealed that she had co-written a song for the album, titled "1-800 Clap Your Hands", and that it would possibly be on her upcoming album. In December 2009, Osment announced plans to start work on her full-length debut album, after promotion for All the Right Wrongs had ended. She continued to write songs while filming the third season of Hannah Montana. She stated that the sound on the album would be different than the music heard on her debut extended play, calling it more of a "mature" sound.

On March 24, Osment confirmed on Good Day NY that her debut album was set to be released in the Summer 2010.^[5] On June 7, 2010, Osment premiered the album's lead single, "Let's Be Friends" on JSYK.com.^[6] On June 3, Osment announced that the album was being pushed back for release in the fall, and later confirmed the album's release date to be October 5, 2010, as well as announcing the official title to be Fight or Flight.^[7] The cover art was revealed August 17, and the track list being revealed on August 20.^[8] When asked about the title of the album, Osment stated

[...] Fight or Flight is a reaction that we have when faced with fear. It’s an uncontrollable, spontaneous reaction when faced with something you’re really afraid of. I’ve always loved that concept that your brain and your body take over, and when it came to this record I started listening to more diverse, different types of bands and I wanted to do what I wanted to do, and I was fighting what I was writing in the past and whatever thoughts anybody else might have, and working to write the music that I love.

The music video for "Let's Be Friends" debuted on Osment's official website on August 23, 2010. She performed the single on The Dome 55. On September 7, the album's second single, "Lovesick", debuted on JSYK.com to generally positive reviews.^[9] It was sent to radio on October 19, 2010^[10] and the music video was released on January 14, 2011.

The album has primarily a dance-pop feel to it, unlike her previous songs. Seventeen Magazine said of the album's composition, " In her first single, “All The Way Up,” she told us, “I like to keep my suitcase packed, cause I’m going far,” and that, she has! Emily has strayed away from her first EP, “All The Right Wrongs” indie vibe, giving her new eleven-song album a more pop-dance feel. The name "Fight or Flight" comes from, Emily's own ambitions to fight through personal anxieties to achieve simultaneous success in two very competitive fields. The first single from Fight or Flight, “Let’s Be Friends,” showcases Emily's ability to make a hit pop-rock song, without sounding manufactured or over-produced. The song has been a popular hit on radio airwaves across the U.S. Other songs likely to be hit singles are "Lovesick," "Truth or Dare," and "All The Boys Want." She slows it down and shows off her vocal ability in "Marisol" and "You Get Me Through." "Right now/live out loud/gotta believe in something," she says in her call-to-action song, "Gotta Believe in Something." If you're in the mood for a high energetic, fun, feel-good song, go right to "Double Talk" or "Get Yer Yah-Yah’s Out." Her song, "1-800 Clap Your Hands (The Water Is Rising)" goes psychedelic-funk while "The Cycle" takes you back to her first EP's alternative-pop feel.^[3]

During an interview about the album's musical content, Osment stated,

[...] I don’t want to write songs that are just surface-deep. I want to be in a world where I’m making the kind of music I want to make, and that’s what I’m doing right now. I want to find a balance between Top 40 songs like ‘Lovesick’ and ‘Let’s Be Friends’ and more complex material like ‘Marisol’ and ‘You Get Me Through’. I’ve given 1000% to making this album, and I won’t settle for mediocrity.^[11]

SparklingStars commented the album's dance melody, stating, "The track “Lovesick” has a great dance beat to it that will get you off your feet and moving, as well as the songs “Get Yer Yah-Yah’s Out” and “The Cycle.” You Get Me Through and Marisol are the two softer tunes on the album, however I found “You Get Me Through” to be a bit too slow. Marisol on the other hand is an amazing song and Emily's voice sounded beautiful. The songs “Double Talk” and “Truth or Dare” had the same beat to me but they work well with the over all sound of the album; and they are the typical club songs that party goes will jam too. The two tracks I believe has the catchiest beats and lyrics are “All the Boys Want” and “Gotta Believe in Something;” they are must listens. But the outcast song is “1-800 Clap Your Hands (The Water is Rising),” I don't really get the sound of the tune although it might fit with the album something is off with it and I would have preferred them to add another softer track instead. Overall if you're looking for good album to play at your next house party check this one. Emily does take a risk by going into a new path with her music early on but it seem like she knows what style she wants to take on; and after all this is only the first of many records to come I'm sure of it."^[12]
