abnormal
Behavior that is culturally inappropriate, is accompanied by subjective distress and involves a psychological impairment and him (inability to cope with life's demands)
-
Cultural Inappropriateness
- the key concept here is that the behavior seems at odds with culture expectations of appropriateness and propriety.
- for example: a person does something that others find disturbing, puzzling, or irrational.
-
Abnormality along the Continuum
- Abnormality should be viewed along a
- continuum
Continuum Model of Abnormality:
1. No clear line between normal and abnormal
2.Requires subjective decisions about when a person has a disorder or not
- 3. The context or circumstances surrounding a behavior influence whether a behavior is
- viewed as Abnormal.
-
Cultural Inappropriateness
- Behavior seems at odds with cultural
- expectations of appropriateness and propriety (something others find
- disturbing, puzzling, or irrational).
- Both the behavior itself and the
- context in which the behavior is displayed is
- important.
- Cultural relativity: the judgment of another person's normality will depend on the values and traditions of the culture in which he
- or she lives.
-
What is Abnormal Behavior?
- Abnormal behavior usually includes the
- following three characteristics:
1.Cultural Inappropriateness
2.Subjective Distress
3. Psychological Disability or Impairment
-
Cultural Inappropriateness
Cultural relativity
This perspective argues that:
Different cultures may utilize different standards in the definition of abnormality.
The norms of society must be used to determine the normality of behavior.
In other words: behaviors can only be abnormal relative to cultural norms.
-
Cultural Inappropriateness
- Another concept related to this is gender
- relativism or gender role expectations – In which behavior can only be defined
- as abnormal if they violate expectations of the an individual based on his or
- her gender.
Gender role expectations influence the labeling of behaviors as normal or abnormal
-
Subjective Distress
- Negative internal emotions or experiences
- which are real to the individual but cannot be observed directly by other
- people.
- Behaviors or feelings that cause the
- individual distress.
- 1. unhappiness,fear, apathy, guilt
- 2. visual and auditory experiences
- 3. physical aches and pains
-
Limitations to Subjective Distress in the Determination of Abnormal Behavior
- Some individuals who display symptoms of
- abnormal behavior may deny any subjective distress
- Examples:
- Manicstates – May deny feeling any distress and often may report that they feel
- wonderful
- AntisocialPersonality – Experience little remorse or distress associated with their
- antisocial behavior
-
Psychological Disability
Individuals who are unable to function adequately in their social roles can be considered to have a psychological disability, impairment, or dysfunction.
- Does the behavior prevent normal daily
- functioning?
- Psychological disability can be considered to be analogous to a physical disability – an
- application of the disease model of
- abnormal behavior.
-
Limitations to Psychological Impairment in the Determination of Abnormal Behavior
- Not all individuals who display symptoms
- of abnormal behavior experience difficulties in their social functions.
Eating Disorders, such as Bulimia
-
What is Mental Health?
Individuals with good mental health tend to share several attributes:
- 1. able to function effectively and to find
- satisfaction in life
- 2. have lasting and emotionally gratifying
- relations
- 3. likely to make a realistic appraisal of
- their own talents and shortcomings
- In sum, good mental health leaves a person open to many alternative ways of
- behaving.
-
By What Name Shall We Call It?
- Many terms have been used to refer to
- abnormal behavior:
1. psychopathology
2. mental illness
3. behavior disorder
4. emotional disturbance
- There is a tendency for any term used in
- reference to these phenomena to acquire a derogatory meaning.
- Mental disorders are
- easier to label than to explain and understand.
-
The current system for identifying and
diagnosing psychological problems is the following:
- The Diagnostic and Statistical Manual
- of Mental Disorders, Fourth Editions, Text Revision or DSM-IV-TR
-
What is a Mental Disorder?
- Mental Disorders are clinically significant behavioral or psychological syndromes are patterns that involve one or more of the following:
- A. Present distress (for example, painful symptoms)
- B. Disability (that is, impairment in one or more important areas of functioning
- C. Significantly increased risk of suffering, death, pain, disability, or important loss of freedom
- Excluded from the definition are syndromes are behavioral patterns that are merely:
- A. Expectable and culturally sanctioned responses to particular events (such as the death of a loved one)
- B. Deviant political, religious, or sexual behavior
- C. Conflicts that are primarily between the individual and society
-
The Scientific Study of Abnormal Behavior
The Case Study
Epidemiological Research
Correlational Research
Experimental Research
-
Diagnostic reliability
Consistency and agreement between clinicians in use of a diagnostic label
-
The Case Study
- An in-depth study of an individual person
- These types of studies have provided a rich source of ideas about the nature and
- causation of abnormal behavior
Case studies cannot be used to "prove" a theory
Can be used to make more general inferences about the sources of psychopathology.
- 1. Selective choices for both the cases
- themselves and for the information reported in regards to a case study
- 2. Findings cannot be generalized to anyone
- other than the person being studied
-
Epidemiological Research
- The study of the incidence or prevalence
- of a disorder in a population
- Looks at the frequency and distribution
- of a disorder, or a group of disorders in a population
Also referred to as normative research
- Data collected through this research
- method can provide important information about public health trends and risks
- across different elements of the population
-
Epidemiological Studies
- Epidemiological studies focus on three
- types of data:
- Prevalence rates –
- The proportion of the population that has the disorder at a given point or
- period in time.
- Incidencerates –
- The number of new cases of the disorder that develop during a specified period
- of time.
- Risk factors –
- The conditions or variables that are associated with a higher risk of having
- the disorder
-
Requirements for Good Research
Random Sampling
Reliability
Validity
-
Random Sampling
- Participant selection by chance from a
- larger population
- This is important, because the sample
- determines to what group(s) of people a given finding can be generalized or
- applied.
-
Reliability of Measurement
- The extent to which a measure consistently yields the same results on repeated
- trials.
The consistency of a test in measuring what it is supposed to measure.
- Interobserver reliability: The
- extent to which different observers (or raters) agree on the way they
- categorize or in some way quantify a given observation.
Psychological measurement is never as precise as physical measurement.
- Psychological measures only sample a
- small part of the domain of how a person acts, or thinks, or feels
-
Validity of Measurement
- A measure is valid if it measures what it
- purports (claims) to measure.
- The accuracy of a test is assessing what
- it is supposed to measure.
- Validity is difficult to determine in
- psychology, as much of what is of interest are constructs: hypothetical or theoretical concepts that cannot be measured directly
aggression; anxiety; intelligence
- A measure can be reliable, and yet not
- valid.
-
Correlational Research
- In a correlational study, the
- investigator investigates the association between two or more measures.
- Correlational coefficient (r) :a statistical measure of the direction and the strength of the relationship
- between two variables
-
Constructs
hypothetical or theoretical concepts that cannot be measured directly
-
construct validity
refers to the availability of some specific way of measuring the hypothetical construct
-
Correlational Research
- Correlation can tell researchers
- something about the strength and direction of a relationship between variables,
- but correlations do not demonstrate
- causation.
- Because of the lack of experimental
- control over the variables measured, there can be an unknown number of other
- variables that might contribute to any observed relationship.
-
Experimental Research
- A research method in which conditions are
- manipulated in order to test the effects of the manipulations on various
- measures.
- The researcher attempts to control
- variables.
- The essence of the psychological
- experiment is that the people to be studied are randomly assigned to two or
- more groups:
Experimental group: Group on which the manipulation of interest is performed
- 1. Control group: Group that is treated similarly to the
- 2. Experimental group, except that no manipulation is performed.
-
Significant difference
A difference unlikely to have occurred by chance and therefore reflecting a real effect.
- 1. In psychological studies, a probability
- of chance findings five of 100 times (p = .05) or lower is accepted as a
- significant difference
-
Placebo effect
- This effect occurs when an expectation of improvement is sufficient to
- cause improvement.
- 1. This effect is particularly relevant for
- pharmacological studies
-
Double-blind design:
- Type of experimental design in which
- both participants and researchers do not know whether a participant is in the
- experimental or the cotrol group.
-
Single-subject experimental designs:
- Experimental methods that do not rely
- on groups of participants, but rather use
- repeated measures from individual people.
