Introduction/ Answering Questions/Surveys/Case StudySection A, B, & C
Attention-deficit/hyperactivity disorder, or ADHA, is not diagnosed by any medical tests but on the behavioral problems
A child must have six or more symptoms of inattention (making careless mistakes in school work, not following instructions, and being easily distracted
A child must also show six symptoms of hyperactivity (fidgeting, leaving, classroom seat, running about when should not, and talking excessively
Since ADHA is not based on medical tests but rather on the occurrence of behavioral problems, how can children with ADHA be distinguished from those who are naturally outgoing and rambunctious
The American Academy of Pediatrics stated that children must be from ages 6 to 12 and be showing symptoms for six months
Ritalin is given to ADHD sufferers and is actually a stimulant that slows down the affects of ADHD
The four goals of Dusty’s case: Describe Dusty’s symptoms Explain their causes Predict their occurrence Control Dusty’s behavior through some behavioral
therapy or drug treatment
Must be careful of the Rhino dust or magic magnet effect in this study
Answering Questions
ADHD is surrounded in controversy– the name has changed three times to go along with that
The possible causes include genetic, hormonal, neurological, and dietary factors
The most popular treatment is giving the child a stimulant drug
The three major methods to study this problem are survey, case study, and experiment
Answering Questions
Survey Survey is a way to obtain
information by asking many individuals to answer a fixed set of questions about particular subjects
The disadvantage is that some information may contain errors or be bias
The advantage is that you obtain a lot of information from a large number of people
Answering Questions
Case Study Researchers gather in-depth data
about a particular individual with a case study
Case study is an in-depth analysis of the thoughts, feelings, beliefs, experiences, behaviors, or problems of a single individual
One disadvantage is that it only applies to one person and may not apply to other children
One advantage is that it allows a greater understanding of a particular person’s life
Answering Questions
Experiment When researchers want to establish a
cause-and-effect relationship they would use an experiment
Experiment is a method for identifying cause-and-effect relationships by following a set of rules and guidelines that minimize the possibility of error, bias, and chance occurrences
Disadvantage is that one result may not apply to all other situations
It is the greatest potential to find cause-and-effect relationship with less error and less bias
Surveys
Although surveys tell us what others believe or how they behave, survey questions can be written to bias the answers, people may not always answer truthfully
Do people wash their hands?—94% said they did on the telephone and a direct survey found that 68% actually did
Surveys provide a great deal of information but have problems with accuracy as well as wording of questions
Surveys
Disadvantages How questions are asked
Would you say that industry contributes more or less to air pollution than traffic?
Would you say that traffic contributes more or less to air pollution than industry?
Same question different result– second question– traffic get more attention
Surveys
Disadvantages Who asks the questions?
Sex or race can affect the outcome of a survey
When asked about sensitive or emotional issues, people take into account the race or sex of the interviewer
Surveys
Advantages If guarded against error
and bias surveys can be a useful research too to collect information on behaviors, beliefs, experiences, and attitudes
Surveys allow people to identify problems and evaluate treatment programs
Case Study
Researchers can answer questions by studying a single individual in great detail, which is a case study
Sometimes case studies can help answer questions but can also result in wrong or bias answers
Observations from case studies may be misinterpreted if the observer has preconceived notions of what to look for
Testimonial is a statement in support of a particular viewpoint based on detailed observations of a person’s own personal experience
To test testimonials researchers will ask teachers and parents to evaluate the behaviors and cognitive functions of children who were ADHD and given a placebo and Aspartame
Case Study
Error and Bias Testimonials are based on our
personal observation, which can be wrong
Personal beliefs can lead to credit an unrelated treatment or event as the reason for some change
Self-fulfilling prophecy having a strong belief or making a statement about a future behavior and then acting, usually unknowingly, to fulfill or carry out the behavior
Case Study
The main disadvantage to a testimonial is their high potential for error and bias
The advantage is providing detailed information that may point to potential answers or lead to future studies
