This course provides an in-depth exploration of the historical and contemporary perspectives on developmental psychopathology. From nineteenth-century conceptions to modern-day approaches, students will delve into the medical model, behaviorism, and organic developmental theories. The implications of these different models, including the use of control groups and the evaluation of psychopathology, will be thoroughly examined. Through a combination of theoretical frameworks and real-world examples, participants will gain a comprehensive understanding of the complexities surrounding child and adolescent psychopathology.

Historical Overview of Course Perspective: Developmental Psychopathology • Nineteenth Century Conceptions of Child Psychopathology—Cicchetti(1984) • Medical model= “main-effects” model used by clinicians (Freud) • Pathological internal agent disturbing homeostasis of organism (e.g., weak constitution) • Pathological external agent disturbing homeostasis of organism (e.g., early childhood trauma) • Academic psychology= empiricism and associationism • Behavior following mechanistically from the action of external determinants in here and now (behaviorism) • Twentieth Century Adherents to These Two Models • Medical model—Freud, clinical psychiatry • Behaviorism—Watson, Pavlov, Hull, Skinner
Contrasts between these two models • While medical model focuses on emotions, behaviorism focuses on cognition • Medical model focuses on pathology, not on development of personality; behaviorism focuses on normal development or immediate stimulus-response, not on pathology. • Developmental psychopathology today—convergence • Clinicians becoming aware of Piagetian and other organismic models of behavior, taking into account more factors • Academic behaviorists abandoning simple theories of classical learning theory in favor of more reality-based model that reflects clinical problems • Implications of Convergence • Collaborative, multidomain, longitudinal studies • Use of control groups to establish baseline, normal behavior • Use of ethology in evaluation of developmental psychopathology—influence of Lorenz (ducks), Tinbergen, Harlow, and others
Contemporary Approaches to Developmental Psychopathology (Cicchetti, 1990) • Psychoanalytic Developmental Approach • Maternal deprivation and problematic mother-child relationshipspsychopathology (Bowlby) • Early life eventslater behavior through concept of “representational models” (Bowlby) • Fixations in stages of differentiation from mother from infantile autism to object-libidinal cathexis of mother (Mahler) • Multiple determinations of psychopathalogical symptoms such as temper tantrum (A. Freud) • Abnormal behavior caused by regression, arrest, or developmental delay (A. Freud)
Organismic developmental approach • Use of normal psychology for understanding abnormal behavior (Werner/Kaplan) • Early levels of normal symbolic functioning and language development parallel to symbolic fuctioning and language development in psychiatric patients (“disintegration”) • Functioning in psychiatric population not hierachically organized or differentiated or integrated • Organism achieves higher levels of organization, differentiation, and integration before regression or disintegration occurs
Piagetian developmental approach • Thinking processes of mentally retarded children demonstrate traces of previous thinking (“viscosity”) • Understanding transitions between stages of development and the meaning of fluctuations (“decalage”) • Psychobiological developmental approach (Meyer) • Constitutional factors modifying individual’s responses to life events • Effects of life events modifying individuals • Use example of temperamentally irritable infant; Nathaniel
Michael Lewis’s contemporary approaches to developmental psychopathology (Lewis, 1990) • Trait or status model ( medical model) • A trait at T1 predicts a trait at T2 • No environmental input • Examples include temperament, particular genetic codes • Attachment construct Mt1 Ct1 Ct2
+ - - + + + • Secure attachment can buffer against stress (still trait) Et1 Et2 Et3 Ct1 Ct1 Ct1 • Introduce idea of critical or sensitive period • When does trait model break down, and environment affect trait (thresholds)? • Duration of stressor • Intensity of stressor • Frequency of stressor • Earlier rather than later in life • Problems with trait model • Situation-specific (secure attachment to mom rather than dad) • No room for environment to affect trait past first few years of life
Environmental model (behaviorism) • Normal or maladaptive behavior is function of environmental forces acting on individual at that time • Individual responds to rewards and punishments • Passive child, active environment • Memories of previous rewards or punishments can affect current behavior (development of representational models) • Different kinds of environments • Dyadic family interactions • Family systems • Peers • Neighborhood effects • Community effects • Gender,ethnicity, cohort, SES effects • Cultural effects
Creation of victim culture (e.g., “murders may be due more to the culture’s non-punishment or nonrestriction of handguns,” p. 19) Are Americans more violent by nature, or do we just permit handguns? • Environmental model Et1 Et2 Et3 Ct1 Ct2 Ct3 assuming homeostatic environment • Effects of attachment (↓ peer relations, ↓ school performance) could be function of homeostatic environment) • Foster care study, changes in mothers’ level of depression
Compare trait and environmental models • Poor parenting insecure attachment poor peer relationships (mediated model) • Poor parenting insecure attachment poor peer relationships • Poor parenting + insecure attachment poor peer relationships (additive model) • Poor parenting * insecure attachment poor peer relationships (moderated model) • Affects of prior experience t1 t2 t3 t4 t5 t1 t2 t3 E + + + + - + + - C + + + + ? + + ?
Interactional model • Stability and change in child a function of child and environment • Trait and environment may act to produce new set of behaviors -Aπ x +E + O not affected OR • Transformational model (transactional model) -Aπ x +E +Aπ + O • Goodness-of-Fit Model • Discord arises when child characteristics do not match environmental demand (e.g., temperament, sex role attitudes) C play x (+) school adjustment C play x (-) school adjustment M (+) attitude toward play M (-) attitude toward play
