Garrison et al. (1995) study

Survey-based study showing higher PTSD rates among adolescents after Hurricane Andrew, notably in African American youths with prior trauma.

Method of Garrison et al. (1995)

Conducted a survey using structured interviews with adolescents.

Key finding of Garrison et al. (1995)

Higher rates of PTSD identified particularly in African American youth with previous trauma exposure.

Exam relevance of Garrison et al. (1995)

Illustrates the biological approach, showing how environmental stressors affect mental health.

Urry et al. (2006) study

Utilized fMRI to demonstrate brain activity during emotion regulation tasks.

Method of Urry et al. (2006)

Used functional Magnetic Resonance Imaging (fMRI) to observe brain activity.

Findings of Urry et al. (2006)

Effective emotion regulation correlates with increased prefrontal cortex activity and decreased amygdala activity.

Exam relevance of Urry et al. (2006)

Aligns with the biological approach, showcasing neural mechanisms in emotion regulation.

Hitchcock et al. (2015) study

Explored hippocampal connectivity in PTSD using resting-state fMRI.

Method of Hitchcock et al. (2015)

Employed resting-state fMRI to assess hippocampal connectivity.

Finding of Hitchcock et al. (2015)

PTSD is linked to disrupted hippocampal connectivity affecting memory and threat detection.

Exam relevance of Hitchcock et al. (2015)

Supports the biological approach, highlighting trauma's effect on brain function.

Gilbertson et al. (2002) study

Twin study analyzing hippocampal volumes and PTSD risk using structural MRI.

Method of Gilbertson et al. (2002)

Compared hippocampal volumes in twins, one with PTSD and one without.

Finding of Gilbertson et al. (2002)

Smaller hippocampal volume may be a pre-existing risk for PTSD.

Exam relevance of Gilbertson et al. (2002)

Contributes to nature vs. nurture debate in psychological disorders.

Irish et al. (2011) study

Investigated autobiographical memory in dementia using neuropsychological assessments.

Method of Irish et al. (2011)

Utilized memory recall tasks to evaluate autobiographical memory performance in dementia patients.

Finding of Irish et al. (2011)

Different dementias affect autobiographical memory retrieval differently.

Luby et al. (2014) study

Longitudinal study employing MRI to track brain development in children in relation to poverty.

Method of Luby et al. (2014)

Conducted MRI scans to correlate brain development with socioeconomic factors.

Finding of Luby et al. (2014)

Poverty stress linked to reduced gray matter in emotion regulation and decision-making areas.
