Self-injurious behavior and stereotypy in an institutionalized mentally retarded population
Applied Research in Mental Retardation
|January 1, 1984
Summary
This study analyzed self-injurious behavior (SIB) and stereotypy in institutionalized clients. Findings suggest these behaviors may stem from physiological mechanisms, potentially requiring new treatments.
Area of Science:
- Neuroscience
- Behavioral Psychology
- Clinical Psychology
Background:
- Self-injurious behavior (SIB) and stereotypy are common in institutionalized populations.
- Current diagnostic and treatment approaches may not fully address the underlying causes of these behaviors.
Purpose of the Study:
- To analyze demographic and behavioral characteristics of institutionalized clients with SIB and/or stereotypy.
- To identify predictors of these behaviors and explore potential new classifications and treatments.
Main Methods:
- Multivariate analyses were used to examine demographic variables and behavioral characteristics.
- Clients were categorized based on the presence of SIB, stereotypy, both, or neither.
Main Results:
- No significant demographic differences were found between groups.
- Behavioral severity, frequency, sensory handicap, and sex were key predictors of group membership.
- SIB and stereotypy may be reclassified as stereotyped SIB and withdrawal stereotypy, respectively.
Conclusions:
- Existing treatments for SIB and stereotypy might be inappropriate due to potential underlying physiological substrates.
- Further research is needed to support a new diagnostic classification and alternative treatments for these aberrant behaviors.

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...
01:19Introduction to Psychological Disorders
Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

01:24Operant Conditioning Intervention
Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.

Dependent personality disorder and obsessive-compulsive personality disorder are two separate psychological conditions that influence behavior, relationships, and overall life functioning. Though both involve maladaptive behaviors, their core characteristics and motivations differ significantly.

Dependent personality disorder is characterized by an excessive reliance on others to manage various aspects of life. Individuals with this disorder often struggle with...

01:20Social Foundations of Self II: The Generalized Other
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group effort.
