Introduction
Speaker: Dr. Cheryl Smith, Clinical Psychologist, Supervisor, and Lecturer at Griffith University.
Clinical focus: Work with individuals across the lifespan, considering factors such as early development, life transitions, culture, trauma, and context.
Supervision of psychologists at various career stages to integrate developmental theory into practical settings.
Emphasis on understanding a person's developmental history and context to comprehend their psychological presentation.
Concept of Development
Goal of the lecture: To broaden the understanding of development as a lifelong and dynamic process rather than limited to childhood.
Key themes:
Development is dynamic and influenced by:
Timing
Culture
Individual life events
Importance of understanding not only what changes but also why, when, and how these changes occur.
Development is shaped by a combination of:
Biology
Experience
Culture
History
Change
Lifespan research shows development as:
Multidimensional
Context-dependent
Domains of Development
Development occurs across interrelated domains:
Physical Development
Includes brain maturation, hormonal changes, sleep patterns, biological health.
Example: Ongoing brain development in the prefrontal cortex affects:
Decision making
Impulse control
Emotion regulation
Changes in sleep and hormones during adolescence affect mood and concentration.
Cognitive Development
Refers to thinking, learning, memory, attention, and executive functions.
Continues into adulthood as we adapt to complex demands in various environments.
Emotional Development
Involves experiencing, understanding, and regulating emotions, as well as building identity and resilience.
Shaped by biology and experience; important for coping with stress, relationships, and transitions.
Social Development
Focuses on relationships, social roles, and cultural norms.
Influences how we relate to family, peers, and broader social circles.
Cultural factors shape values, expectations, and behavior.
Interaction across domains: Changes in one domain can trigger changes in others.
Example: Disrupted sleep from stress can impair attention and emotion regulation.
Importance of seeing development as an interactive process across all domains.
Non-Linear Development
Development is not linear; it doesn’t follow a straight upward trajectory.
Life periods consist of varying patterns of gains, adjustments, and losses.
Example: Adolescence is marked by cognitive growth and emotional volatility.
Early adulthood involves identity consolidation rather than rapid change.
-. Later adulthood may show cognitive processing decline but improved emotional regulation.
Reference to Carstensen's social-emotional selectivity theory:
As people age, they prioritize emotionally meaningful relationships over novelty.
Nature vs. Nurture
Modern understanding: Development results from a reciprocal interplay between biology and environment.
Genes as a blueprint with potential predispositions, e.g., anxiety or impulsivity.
Experience shapes the expression of genetic potential, influenced by:
Caregiving quality
Exposure to stress
Social support
Life events
Individuals act as active shapers of their environments.
Example: A child with genetic vulnerability to stress in a stressful environment may face anxiety, whereas a supportive environment could mitigate this.
Epigenetics: Early life stress can alter gene expression related to stress regulation, impacting development over time.
Major Categories of Developmental Influences
Normative Age-Graded Influences
Experiences shared by most people at similar ages.
Examples:
Language acquisition
Puberty
Identity exploration in emerging adulthood
Menopause
Significance of understanding developmental tasks appropriate for age.
Example: A 19-year-old’s impulsivity may reflect developmental immaturity rather than dysfunction.
Normative History-Graded Influences (Cohort Effects)
Shaped by historical events during development.
These influences affect attitudes, behaviors, and socio-cultural interactions.
Example:
COVID-19 pandemic shaped university experiences and mental health for students.
Research by Chwenz and Campbell indicated a rise in adolescent anxiety correlating with social media adoption.
Contextual issues reflect on developmental experiences, not solely individual vulnerabilities.
Non-Normative Life Events
Unique, unshared experiences affecting development (not time-bound).
Examples include migration, serious illness, loss of a caregiver, or early caregiving responsibilities.
Impact of non-normative events depends on timing, accumulation of stressors, and availability of support.
Example: Loss of a primary caregiver can disrupt emotional regulation, depending on the subsequent supportive environment.
Cultural Context in Development
Cultural environments shape coping strategies, support systems, and developmental outcomes.
Example: Collectivist vs. individualistic cultures impacts stress response and support during adversity.
Collectivist cultures often provide shared support, mitigating psychological stress.
Individualistic cultures may limit access to support systems during stress, increasing vulnerability.
Case Example: Ayesha
Profile:
20-year-old psychology undergraduate, first in family to attend university.
Experienced high school during the COVID-19 pandemic.
Reports high anxiety and self-doubt, lives with financial stress.
Feels pressured by social media connectivity.
Analysis of Ayesha using a lifespan perspective:
From a normative perspective:
In emerging adulthood, characterized by identity exploration and decision-making uncertainties.
From a historical perspective:
Constant connectivity and pandemic experiences shape her self-assessment and social interactions.
From a non-normative perspective:
Family financial hardships increase personal responsibility and performance pressure.
Cultural context:
First-generation student issues such as unfamiliarity with university systems and expectations to succeed.
Conclusion
Development is a complex, contextual process influenced by multiple factors and ongoing interactions over time.
Highlights importance of viewing behavior within context rather than pathologizing it.
Development reflects multidimensional influences: biological changes, historical and cultural contexts, and unique individual experiences.
Overall Significance
Understanding development as dynamic and interrelated allows for informed, compassionate psychological practices considering broad influences beyond singular factors.
Essential for modern developmental psychology to adopt an inclusive approach to human behavior and development.
