The Life-Course Theory of Serial Killing: A Motivation Model
1D.G. Vaishnav College, Chennai, India.
International Journal of Offender Therapy and Comparative Criminology
|December 18, 2020
Summary
This study introduces a novel life-course model for understanding serial killer motivation, identifying "nature," "Deep Resting Life Factor," and "key Incidents" as critical determinants. It highlights that interactions between factors, not standalone elements, are crucial in developing criminal behavior.
Area of Science:
- Forensic Psychology
- Criminology
- Behavioral Science
Background:
- Serial killer motivation is complex and often explained by rigid, limited models.
- Previous research has not adequately addressed the life-course development of serial offenders.
- A localized study on Indian serial killers is needed to understand regional criminal typologies.
Purpose of the Study:
- To develop an inclusive motivation model for serial killers using a life-course approach.
- To analyze the life histories of eight Indian serial killers to identify developmental factors.
- To test the applicability of the proposed model across diverse offender cases.
Main Methods:
- Conducted case studies on eight serial killers incarcerated in Indian prisons.
- Collected data through in-depth interviews, relative interviews, victim testimonies, and crime scene analysis.
- Chronologically arranged life data to construct offender biographies for analysis.
Main Results:
- Proposed a unique, flexible motivation model with three determinants: nature, Deep Resting Life Factor, and key Incidents.
- Identified a 'trigger' incident in six cases, initiating latent violent tendencies.
- Found that the interaction of recurring factors, rather than individual factors, significantly influences serial offending.
Conclusions:
- The developed life-course model offers a more comprehensive understanding of serial killer evolution.
- There are no predetermined 'recipes' for creating serial killers; individual life trajectories are key.
- The study provides a novel framework applicable beyond the specific cases examined.

Affiliation motivation is the intrinsic desire to connect with others and belong to a social group, which plays a crucial role in forming and maintaining personal relationships. This type of motivation is essential for psychological well-being, as it provides individuals with a sense of community and support. An example of this is a student who joins a study group in order to feel a sense of connection. People with high affiliation motivation actively seek social approval, take satisfaction in...

01:14Psychosexual Theory of Development
1.4K
Sigmund Freud's psychosexual theory of development suggests that early childhood experiences significantly shape personality and behavior. Freud proposed that development is discontinuous, occurring in five distinct stages, each defined by a focus on different erogenous zones. He believed that failure to resolve the conflicts specific to each stage successfully could result in fixation, potentially influencing behavior as adults.

Kohlberg's theory of moral development uses the Heinz dilemma — a thought experiment in which a man, Heinz, must decide whether to steal an unaffordable drug to save his dying wife — to illustrate the evolution of moral reasoning. This framework, divided into three levels with two stages, highlights how individuals' understanding of right and wrong becomes increasingly complex.

01:29Theory of Attribution II: Kelley's Covariation Theory
232
Attribution theory plays a crucial role in social psychology, helping to explain how individuals interpret the causes of behavior. One prominent model within this field is Harold Kelley's covariation theory, which provides a systematic approach to determining whether internal traits or external circumstances drive a person's actions. The model posits that individuals rely on three key types of information—consensus, consistency, and distinctiveness—to make these judgments.Consensus:...

01:27Drive-Reduction Theory: Push Theory of Motivation
819
Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or...

Power motivation and achievement motivation are two essential social motives identified by psychologist David McClelland. These motives influence behavior in various personal and professional contexts, shaping how individuals interact with others and pursue their goals.
Power motivation is characterized by the desire to influence, control, or have an impact on others. It is shaped by an individual's experiences, social environment, and cultural context. People with high power motivation are...
