LECTURE 2

Systematic Observational Methods:

1. Tally

(Frequency Count)

Operational Definition:

Defining the behavior in terms of observable events

Aggression:

·  Any non-verbal physical contact

(Is this a good operational definition?)

Hitting:

·  Close fisted contact by the child against another person, animal, or inanimate object. Contact is made quickly and is not prolonged. Each time fist is extended, contacts, and is withdrawn counts as one hit

Slapping:

·  Same definition as hitting, except open-handed instead of close-fisted

Shoving:

·  Simultaneously placing two open hands against person or object for longer than a slap, and exerting force in an attempt to displace the location of the object

Observation of Aggression

(you will need to come to class to see this slide)

Obnoxious Behaviors of Normal Child:

  • 2 yr. olds: 1.00 response per minute
  • 3 yr. olds: .87 response per minute
  • 4 yr. olds: .75 response per minute
  • 5 yr. olds: .50 response per minute

Girls' Social Interaction & Ritalin
(you will need to come to class to see these slides)

How to Treat Children with ADHD:

  • Drug therapy (Ritalin), plus
  • Behavioral therapy (programs designed to teach task focus and impulse control), plus
  • Parent training

Operational Definitions:

  • "Terrible attitude"
  • Intelligence
  • Anxiety

Colic:

·  Inconsolable crying for which no physical cause can be found, which lasts for more than three hours day, occurs at least three days a week or more, and continues for at least three weeks

Systematic Observational Methods (Cont):

2. Duration

3. Interval

Aggressive Behaviors & Time of Day
(you will need to come to class to see these slides)

Aggression:

  • Stable across settings (50% chance of home and school reports coinciding)
  • Stable across time (continuity extends into adulthood)
  • Usually emerges quite early (by age 8)
  • "High variety" children most at risk

Undercontrolled Disorders:

  • Childhood behavior problems that involve "externalizing", i.e., acting out difficulties in ways that disturb other people
  • Examples: ADHD, aggression, conduct disorder (persistant antisocial behavior)

Overcontrolled Disorders:

  • Childhood behavior problems that involve "internalizing" difficulties in ways that cause inner distress
  • Examples: depression, anxiety, phobias, severe shyness and social withdrawal

Do Childhood Behavior Problems Persist?

  • Overall, there is more discontinuity than continuity in childhood behavior problems
  • That is, most children with "at risk" temperaments do not have diagnosable problems as adults
  • However, there is continuity in many individuals for autism, ADHD, major depression, and antisocial behavior
  • Moreover, undercontrolled children at age 3 (described as irritable, impulsive, rough) are more likely than other children to become antisocial adults with criminal records
  • Overcontrolled, inhibited children at age 3 (described as shy, anxious, easily upset) are more likely as adults to be diagnosed as depressed (but not anxious)

What Causes Childhood Disorders?

  • Research shows that children with psychological disorders often come from problem-ridden families
  • They are more likely to have parents who are disturbed themselves
  • Poor parenting is also implicated: children with behavior problems are more likely to have hostile or rejecting parents

But is "poor parenting" the only explanation?

Many childhood disorders are partially genetic, and may be the cause, as well as the effect, of problems in the parent/child relationship

How Are Childhood Disorders Best Treated?

  • Psychotherapy works at least as well with children as it does with adults
  • Undercontrolled, externalizing problems are just as responsive as overcontrolled, internalizing problems
  • Behavioral therapies (e.g. reinforcement, modeling) are more effective than nonbehavioral ("talking") therapies
