On the evolution of attachment-disordered behaviour

Area of Science:

• Ethology
• Psychoanalysis
• Developmental Psychology

Background:

• Isolation and lack of a secure primary attachment object can lead to developmental issues.
• Fear significantly impacts behavior, hindering the formation of new attachments.
• Unresolved conflicts between the urge for attachment and fear result in disordered behaviors like displacement activities and apathy.

Purpose of the Study:

• To investigate the impact of isolation on attachment and escape behavior using a gosling model.
• To explore the relationship between fear, attachment, and behavioral development.
• To draw implications for human behavior and psychological disorders.

Main Methods:

• Observation of a gosling raised in complete isolation.
• Analysis of behavioral changes in response to environmental modifications (reduction of escape motivation).
• Synthesis of ethological and psychoanalytical theories.

Main Results:

• Isolation progressively increased escape behavior in the gosling.
• Attachment-disordered behaviors, including displacement activities and apathy, were observed.
• Reduction of escape motivation facilitated the return to normal attachment behavior and the acceptance of offspring.
• Displacement activities and apathy ceased once normal attachment was re-established.

Conclusions:

• Fear and attachment, rather than aggression and sexuality, are primary drivers of social development in animals and humans.
• A healthy balance between fear and attachment is crucial for the development of social relationships.
• Findings suggest potential therapeutic approaches for attachment disorders by managing fear and fostering secure attachments.
