Which Of The Following Behaviors Is Not An Inherited Behavior

which of the following behaviors is not an inherited behavior is a question that cuts to the heart of the nature‑versus‑nurture debate in psychology and biology. In this article we will unpack the concepts of inherited (genetic) behaviors and learned (environmental) behaviors, examine concrete examples, and finally pinpoint the behavior that does not pass from parent to offspring through DNA. By the end, you will have a clear, evidence‑based answer and a richer understanding of how our minds and bodies acquire the actions that shape daily life.

Understanding the Basics: Inherited vs. Learned Behaviors

Genetic Basis of Inherited Behaviors

Behaviors that are inherited are those that arise automatically because the underlying neural circuits are encoded in an organism’s genome. These traits often manifest without prior experience and are observable across members of the same species. In evolutionary terms, they serve adaptive functions such as avoiding predators, securing mates, or navigating the environment. The genetic blueprint for these actions is transmitted from parents to offspring through DNA, making them a cornerstone of instinct and reflex pathways.

Learned Behaviors: Shaped by Experience

In contrast, learned behaviors develop through interaction with the environment, cultural transmission, or personal experience. They are not hard‑wired; rather, they emerge as the brain forms new synaptic connections in response to stimuli. Learning can occur via conditioning, observational imitation, or formal instruction, and the resulting patterns can vary widely even among individuals who share the same genetic background.

Common Examples of Inherited Behaviors

• Newborn reflexes: The Moro reflex (startle response) and the rooting reflex appear in human infants without any prior exposure.
• Species‑specific instincts: Migratory patterns in birds, web‑spinning in spiders, and the fight‑or‑flight response in mammals are all genetically programmed.
• Innate social cues: Many primates display automatic facial expressions such as fear grimace or submissive bow when encountering dominant individuals.

These behaviors are typically hard‑wired, meaning they emerge spontaneously and are repeatable across generations.

Behaviors That Are Primarily Learned

• Language acquisition: While humans possess a predisposition for language, the specific grammar, vocabulary, and pronunciation are acquired through exposure and practice. - Social customs: Greeting rituals, table manners, and holiday traditions differ across cultures and are transmitted through teaching and imitation.
• Skill mastery: Playing a musical instrument, riding a bicycle, or solving mathematical problems require deliberate practice and feedback.

These actions rely heavily on experience‑dependent plasticity, meaning the brain rewires itself based on repeated activity.

Identifying the Non‑Inherited Behavior

To answer the central query—which of the following behaviors is not an inherited behavior—let’s consider a typical multiple‑choice scenario often used in introductory psychology courses:

1. The newborn’s Moro reflex – a sudden extension of arms followed by a hugging motion.
2. A fear of snakes – an automatic aversion that appears even in infants raised in snake‑free environments.
3. The ability to speak a native language – the capacity to produce phonemes unique to one’s linguistic community.
4. The instinct to blink when an object approaches the eye – a protective visual reflex present at birth.

Analysis of Each Option

• Option 1: The Moro reflex is a classic example of an inherited behavior; it appears without training and is observable in all healthy newborns.
• Option 2: Fear of snakes, while often exaggerated by cultural stories, has a strong genetic component; studies show infants display heightened physiological responses to snake‑like shapes.
• Option 4: The blink reflex is hard‑wired into the visual‑motor pathway and therefore inherited.
• Option 3: Speaking a native language, however, is not encoded in the genome. Babies are born with the capacity for speech, but the specific language they acquire depends entirely on the linguistic input they receive during early development. This makes language acquisition a quintessential learned behavior.

Therefore, the behavior that is not inherited is the ability to speak a native language (Option 3). It requires environmental exposure, cultural transmission, and continual reinforcement—hallmarks of learning rather than genetic inheritance.

Scientific Explanation: Why Language Is Learned

1. Critical period hypothesis – Research indicates that there is a window of heightened neuroplasticity during early childhood when language acquisition is most efficient. Outside this period, acquiring a new language becomes markedly more difficult.
2. Statistical learning – Children unconsciously detect patterns in

...the speech stream—identifying syllable boundaries, common phoneme sequences, and syntactic regularities—without explicit instruction. This innate statistical processing ability, however, extracts the rules of whatever language is present in the environment; it does not pre-specify a particular language like English or Mandarin.

3. Social-pragmatic scaffolding – Language acquisition is deeply embedded in social interaction. Caregivers use infant-directed speech, follow the child’s attentional focus, and provide contingent responses (e.g., labeling objects the child looks at). This joint attention and reciprocal communication is a culturally mediated learning process, not a genetically programmed sequence for a specific tongue.

4. Neurobiological evidence – While Broca’s and Wernicke’s areas are crucial for language processing, their functional organization is shaped by experience. Neuroimaging studies show that the neural circuits for processing the phonetic and syntactic structures of one’s native language become specialized through exposure, whereas non-native language patterns recruit different or additional networks. The brain is primed for language, but the specific content is environmentally installed.

Conclusion

The distinction between inherited and learned behaviors hinges on whether a trait emerges predictably without prior experience or requires environmental input for its manifestation. The Moro reflex, an innate snake aversion, and the blink reflex are robust, universal responses present at birth, products of evolution encoded in our DNA. In stark contrast, the ability to speak a native language—while resting on a biological foundation of vocal apparatus and a predisposition for linguistic processing—is fundamentally a learned behavior. Its specific form is not inherited; it is meticulously constructed through exposure, social engagement, and practice within a particular cultural milieu. Thus, among the options presented, speaking a native language stands as the clear example of a behavior transmitted not by genes, but by teaching and imitation. This case powerfully illustrates that even our most defining human capacities can be shaped more by nurture than by nature.
