Why we behave the way we do:
psychologists and behavioural scientists look through several different
"lenses" or frameworks. Each perspective offers a unique explanation
for what drives our actions, shapes our adaptability, and defines our reality.
Here are four major
psychological frameworks that explore the how and why of human behaviour:
1. The Biopsychosocial
Framework
This is one of the most
comprehensive models in modern psychology. It posits that behaviour is never
shaped by just one factor; instead, it is the result of a constant interplay
among three core dimensions:
Biological Factors:
Genetics, brain structure, neurotransmitters, and overall physiological health.
For example, stress hormones or neurological development heavily influence our
impulse control and emotional regulation.
Psychological Factors:
Personality traits, coping styles, past learning experiences, and emotional
interpretations. How we perceive a situation dictates how we react to it.
Social Factors: Cultural
norms, family background, socioeconomic status, and peer groups. Society
establishes baseline expectations for "normal" and adaptive behaviour.
2. Cognitive Psychology
(Information Processing)
Cognitive psychologists
compare the human mind to a complex computer system. This framework focuses on
how we process information—how we take in sensory input, interpret it, store it
in memory, and use it to make decisions.
Why we behave as we do:
Behaviour is driven by our internal mental maps and beliefs. If our cognitive
appraisal of a situation is distorted (for instance, misinterpreting a neutral
glance as a threat), our behavioural response will reflect that distortion. Conversely,
clear reality orientation allows for measured, adaptive responses.
3. Behavioural and Social
Learning Theories
Rooted in the work of
theorists like Ivan Pavlov, John B. Watson, and B.F. Skinner, and later
expanded by Albert Bandura, this perspective emphasises that behaviour is
largely learned from our environment.
Classical and Operant
Conditioning: We repeat behaviours that are rewarded or reinforced, and we
extinguish behaviours that lead to negative consequences (linking directly back
to understanding cause and effect).
Observational Learning:
Bandura demonstrated that we also learn simply by watching others. We adopt
social scripts and coping mechanisms by observing family members, peers, and
cultural role models.
4. Evolutionary Psychology
. Behavioural Adaptability
vs. Rigidity
Normal Behaviour:
Demonstrates situational flexibility, allowing a person to adjust their coping
mechanisms, emotional responses, and actions as circumstances change.
Abnormal Behaviour: Often
involves cognitive or behavioural rigidity—such as compulsive routines,
maladaptive coping patterns, or an inability to modify responses even when a
situation completely changes (frequently seen in anxiety disorders,
obsessive-compulsive patterns, or personality disorders).
2. Insight into Cause and
Effect vs. Impaired Insight
Normal Behaviour: Features
a clear grasp of logical consequences, accountability, and the relationship
between one's actions and external outcomes.
Abnormal Behaviour: Can
involve impaired insight (or lack of awareness regarding the impact of one's
actions).
In more severe psychological contexts, it can
manifest as delusions, magical thinking, or an inability to connect personal
behaviour to recurring negative life consequences.
3. Reality Orientation vs.
Disorientation / Altered Perception
Normal Behaviour: Maintains
orientation to person, place, and time (keeping a stable anchor in shared
consensus reality).
Abnormal Behaviour: May
involve disorientation, confusion, or a disconnection from reality—such as
experiencing hallucinations, severe dissociation, or acute cognitive impairment
(which can stem from trauma, neurocognitive disorders, or psychosis).
Would you like to look
closer at how specific psychological frameworks (like the DSM criteria or
functional definitions of mental health) classify these distinctions?
It is true that human
behaviour—especially when it crosses into harmful or criminal acts—is one of the
most complex puzzles we can study. Looking at both sides of the coin means
holding two truths at once: acknowledging the profound impact and accountability
for actions, while also seeking to understand the deep roots of why people do
what they do.
When criminologists,
psychologists, and neuroscientists look at what drives criminal behaviour and
other extreme patterns, they find that it rarely stems from a single cause.
Instead, it is almost always a convergence of multiple risk factors.
Key Factors Behind
Criminal and High-Impact Behaviours
1. Neurobiological and
Genetic Vulnerabilities
Science shows us that
biology is not an absolute destiny, but it plays a foundational role. Research
into brain structure (such as differences in the prefrontal cortex, which
governs impulse control and decision-making) and neurotransmitters (like serotonin
and dopamine, which affect mood and risk-taking) reveals that some individuals
have a harder time regulating aggression or evaluating consequences.
Genetic predispositions
can interact with environmental stress, making certain individuals more
vulnerable to impulsivity or antisocial tendencies.
2. Developmental and
Environmental Background
Early Adversity: A
significant portion of chronic criminal behaviour traces back to severe
childhood trauma, neglect, abuse, or chronic exposure to violence. When a
child's brain develops in a constant "survival mode," it alters how
they process threat, empathy, and emotional regulation.
Social Learning: Building
on behavioural theories, individuals who grow up surrounded by antisocial
models—where criminal behaviour is normalised, rewarded, or seen as the only
viable survival strategy—often adopt those same behavioural scripts.
3. Cognitive Appraisals
and Moral Reasoning
Looking back at our
earlier discussion on insight and cause-and-effect, some individuals exhibit
distorted cognitive processing. This can manifest as an inability to empathise
with victims, externalising blame ("It wasn't my fault, the world is against
me"), or short-term thinking that completely discounts future
consequences.
4. Situational and
Environmental Pressures
Not all criminal or
extreme behaviour stems from lifelong patterns. Acute situational pressures—such
as sudden economic desperation, intense social peer pressure, substance
intoxication, or high-stakes emotional triggers—can cause individuals to act
completely out of character compared to how they would behave in a calm, stable
environment.
Expanding Beyond Crime:
Why Other Complex Behaviours Happen
The same multidimensional
lens applies to other complex human behaviours, such as addiction, altruism, or
extreme risk-taking:
Addiction: Driven by a mix
of genetic vulnerability in the brain's reward pathways, psychological coping
mechanisms for trauma, and social environments where substances are accessible.
Altruism and Resilience:
Conversely, why do some people who experience immense hardship become deeply
compassionate helpers or community advocates? Psychology points to protective
factors—such as having at least one stable, supportive adult mentor in childhood,
or developing a strong internal sense of meaning and agency.
Exploring these two
sides—holding individuals accountable for the ripple effects of their actions
while examining the complex machinery of the human mind—is precisely what helps
society move toward better prevention, rehabilitation, and mental health support.
Which of these
intersecting roots—biology, early environment, or cognitive processing—stands
out most to you when thinking about human behavior?
