Millions of custodial suspects waive their Miranda rights each year without the benefit of legal counsel.

Mired in Miranda misconceptions: a study of legally involved juveniles at different levels of psychosocial maturity.

The Supreme Court of the United States has long recognized that the vulnerabilities of juvenile offenders merit special protections due to deficits in experience and maturity.

Decrements in Miranda abilities: an investigation of situational effects via a mock-crime paradigm.

Programmatic research has made important advances during the last decade in understanding how cognitive and psychological variables affect Miranda comprehension and reasoning. However, the effects of situational stressors are largely overlooked in determining the validity of Miranda waivers. As the first systematic investigation, this study uses a 2 × 2 × 2 factorial design on 123 undergraduate participants to examine the effects of being apprehended via a mock crime (i.
