An “Acoustic Observation” Sampling Approach
PDA-based recording software Samples snippets of ambient sounds e.g., 30 sec every 12.5 min (4% of the day)
≈ 70 sound files per day

Knowing me, knowing you:The relative accuracy and unique predictive
validity of self-ratings and other-ratings of daily behavior
Vazire & Mehl, JPSP, 2008
Most people assume they know themselves better than anyone else knows them.
Reviewer C: “the best criterion for a target’s personality is his or her self-ratings … Otherwise, the whole enterprise of personality assessment seriously needs to re-think itself”
But how do you test the relative accuracy of self- and other knowledge?
Knowing Me, Knowing You
N = 80 college students wore the EAR for 4 days Participants and 3 informants rated the participants on how
much they engage in 20 daily behaviors. The EAR-assessed frequency with which participants actually
engaged in these behaviors was used as accuracy criterion.
How Accurate Were Self- and Other-Ratings?
r = .26
r = .26 (.23)

Self and others are equally (in)accurate and possess unique insight into how a person typically behaves.

Are Women Really More Talkative Than Men?

“All of this is hardwired into the brains of women. These are the talents women are born with that many men, frankly, are not”

A Funny Take on It …
Or Closer to the Truth …
Naturalistic observation allows for the assessment of subtle social behaviors that evade self-reports
Eavesdropping on Happiness
Mehl, Vazire, Holleran, & Clark, Psych Science, 2010
Is the happy (daily) life full of superficial, happy-go-lucky moments or full of profound social encounters (“happy ignoramus” vs. “fulfilled deep thinker”)?
Eavesdropping on Happiness
96 participants wore the EAR for 4 days Well-being was assessed with self-reports of life-
satisfaction and self- and informant reports of happiness EAR codings
Time spent alone, time spent with others Small-talk (uninvolved conversation of a banal nature; only trivial
information gets exchanged) Substantive conversations (involved conversation of a substantive
nature; meaningful information gets exchanged)
Eavesdropping on Happiness
The happy daily life is social rather than solitary and conversationally deep rather than superficial.
r = -.35 & r = .31, ps < .01 r = -.33 & r = .28, ps < .01
Summary
It allows us to study actual, real-world behavior in addition to (global, retrospective, or momentary) perceptions of such behavior.
This is important because only that way can we learn about what causes
convergence of and discrepancies between the two. ultimately, actual, real-world behavior tends to be
the (explicit or implied) end-point of our theories.
In essence, what is the added value of naturalistic observation with a method such as the EAR?
“We wish to suggest, gently and respectfully,that social and personality psychology try toput a bit more behavior back into the scienceof behavior (…). We advocate a renewedcommitment to including direct observation ofbehavior whenever possible and in at least ahealthy minority of research projects.”

The Broader Context of this Research
SighingSwearing
the participants for sharing the sounds of their personal daily lives. the research assistants for coding and transcribing the EAR sound files.
James Pennebaker, Sam Gosling, Simine Vazire, Jason Rentfrow, Nairan Ramirez, Andrea Garcia, Shannon Holleran, Megan Robbins, and all the other people who directly or indirectly contributed to the projects. The NIH (R03CA137975) and ACS (IRG-74–001–28) for their support.
