This volume 5.2 of the Nature Nurture Journal of Psychology brings together cutting-edge research in cognitive and clinical psychology, emphasizing the development, validation, and application of psychological assessment tools, experimental investigation of cognitive and emotional processes, and neurocognitive mechanisms underlying human behavior. Highlights of this volume include: the psychometric development of the Coercive Control Scale for married individuals in Pakistan; exploration of the effects of experimentally induced visual and auditory hallucinations on cognitive and emotional functioning in schizophrenia and healthy populations, with a focus on placebo modulation; examination of cognitive debt in emerging adults in the era of artificial intelligence; and a meta-analytic review of neural correlates of placebo analgesia and emotion regulation. This issue also presents cross-cultural validation studies, such as the Urdu version of the Delaware School Climate Survey-Student (DSCS-S), showcasing the integration of psychometric rigor, cognitive neuroscience, and experimental psychology. Collectively, this volume represents the forefront of research bridging theory, assessment, and applied cognitive interventions in diverse populations.
