Theoretical Approaches to Psychological Disorder

Theoretical Approaches to Psychological Disorder

The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Social Facilitation

Social Facilitation

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Behavior Modification

Behavior Modification

Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.

Confirmation Biases

Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Evolutionary Psychology

Evolutionary Psychology

Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Autism Spectrum Disorder

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Summary

Psychological factors like anxiety significantly impact eye conditions such as accommodative anomalies. A psychological approach, rather than solely ocular treatment, can effectively resolve these vision issues by addressing underlying stress and anxiety.

Area of Science:

Ophthalmology
Psychology
Optometry

Background:

Accommodation anomalies are often linked to psychological issues like anxiety, similar to other somatic symptoms.
Ocular treatments alone are frequently insufficient for these complex cases.

Purpose of the Study:

To report the characteristics and outcomes of patients with accommodation spasms and weaknesses.
To outline a psychological approach for treating these vision anomalies.

Main Methods:

23 patients (aged 8-30) with diagnosed accommodative anomalies underwent objective assessment (photorefractive method, orthoptic testing, dynamic retinoscopy).
An evidence-based psychological approach was integrated to address stress and anxiety's role in eye symptoms.

Main Results:

83% of patients were female; 57% had prior anxiety or dyslexia diagnoses.
Inconsistent responses were common, often differing between subjective and objective measures.
Significant improvement occurred within one session after discussing the anxiety-accommodation link; no patients required further treatment.

Conclusions:

Psychological factors are crucial in causing or worsening accommodation and convergence anomalies.
Recognizing ocular symptoms as potential signs of anxiety, not primary problems, aids treatment.
A psychological approach can help patients manage triggering issues, leading to symptom resolution and avoiding solely ocular interventions.
