This Unit introduces you to the basic concepts of psychology that will help you understand the biological and social bases of human behavior. It examines aspects of physical, cognitive, social, and emotional development and how they relate to social work practices. This Unit also includes a module on working with specific vulnerable populations that will focus on responding to concerns and strategies to keep us and others safe and support these individuals and groups. Mental health is an emerging issue in modern life affecting the welfare of many Australian individuals, affecting their capacity to work, sustain relationships, and live independent and satisfying lives. Psychosocial interventions are thus important to be able to work with people experiencing mental health problems across a wide range of health and welfare settings. This Unit provides foundational knowledge and skills for social practice in these diverse areas. This knowledge and its application are aimed at preparing graduates for person-centered, evidence-based generic social work practice.
