Do people know whether they are overweight? Concordance of self-reported, interviewer-observed, and measured body size

Do researchers know what they are doing?

Do people know how they behave? Self-reported act frequencies compared with on-line codings by observers.

Behavioral acts constitute the building blocks of interpersonal perception and the basis for inferences about personality traits. How reliably can observers code the acts individuals perform in a specific situation? How valid are retrospective self-reports of these acts? Participants interacted in a group-discussion task and then reported their act frequencies, which were later coded by observe...

Concordance between self-reported and measured HIV and hepatitis C virus infection status among people who inject drugs in Germany

Background: People who inject drugs (PWID) are disproportionately affected by both HIV and hepatitis C infection (HCV). Awareness of infection status is essential to ensure linkage to appropriate healthcare for those infected, who need treatment and regular follow-up, as well as for uninfected individuals, who need access to targeted testing and counselling services. In this paper we compare se...

Do animals know what they know ?

Using well-established paradigms for studying animal perception and memory, researchers have begun to ask whether animals can monitor the status of their knowledge in a behaviour al task whether they know what they know. Generally, such metacognitive ability is tested by giving animals the opportunity to avoid (or ‘escape’) a test of memory or perceptual discrimination. The pattern of escapes c...

Self-ratings of type A (coronary prone) adults: do type A's know they are type A's?

This study compared self-ratings and interview-band ratings of the type A coronary-prone behavior pattern. A Type A adjective scale was developed from the Gough-Adjective Checklist (ACL), using adjectives rated as characteristic and uncharacteristic of the Type A individual by a panel of 20 Type A researchers. Scores on this scale were compared with Type A ratings based on the structural interv...
