9.1 Introduction to Psychology: Psyche, Consciousness & the Cognitive Process
Key Takeaways
- Psychology derives from psyche (soul or mind) and logos (study); it is defined today as the scientific study of behaviour and mental processes.
- The Indian conception of the psyche is the Antahkarana Chatushtaya - Manas, Buddhi, Ahamkara and Chitta - which is subtle matter, not consciousness itself.
- Western psychology describes three levels of consciousness (conscious, subconscious, unconscious) while Vedanta describes four states (Jagrat, Svapna, Sushupti, Turiya) - the two schemes are not equivalent.
- The cognitive process runs sensation, attention, perception, memory, thinking and reasoning; Patanjali's five Vrittis cover the same ground in a different vocabulary.
- Patanjali's three Pramanas - Pratyaksha, Anumana and Agama - correspond to the three sources of knowledge recognised in cognitive psychology as direct experience, inference and testimony.
9.1 Introduction to Psychology: Psyche, Consciousness & the Cognitive Process
Unit 3 devotes five of its twenty items — 3.6 to 3.10 — to psychology. That is a quarter of the unit, and candidates from a traditional yoga background regularly arrive unprepared for it. This section covers item 3.6: introduction to psychology, the concept of the human psyche, the stages of consciousness, and the cognitive process, its meaning and nature.
What psychology is
Psychology = Greek psyche (soul, mind, breath) + logos (study, discourse). The etymology is worth noting: the discipline began as the study of the soul, became the study of the mind, and is today defined as:
The scientific study of behaviour and mental processes.
Three words carry the definition. Scientific — systematic, empirical, replicable. Behaviour — what is observable and measurable. Mental processes — the internal events inferred from behaviour and, increasingly, from physiological measurement.
Its historical arc
| Phase | Definition of the subject | Turning point |
|---|---|---|
| Ancient–17th c. | Study of the soul | Philosophical, not empirical |
| 17th–19th c. | Study of the mind | Introspection as method |
| 1879 | Study of conscious experience | Wilhelm Wundt opens the first psychology laboratory at Leipzig — the conventional birth date of psychology as a science |
| Early 20th c. | Study of behaviour | Watson and Skinner; consciousness rejected as unobservable |
| Mid–late 20th c. | Study of behaviour and mental processes | The cognitive revolution restores internal processes |
Branches relevant to a yoga teacher
General, developmental, social, abnormal, health, educational, positive psychology (well-being rather than pathology), and psychophysiology (the bodily correlates of mental states) — the last two being where yoga research mostly sits.
The concept of the human psyche
The Indian account: Antahkarana Chatushtaya
Antahkarana means the inner instrument, and it has four functions. The critical philosophical point, and the one most often missed, is that in Samkhya-Yoga the psyche is not consciousness. It is subtle matter (sukshma dravya), an evolute of Prakriti. Consciousness is Purusha, which is not part of the instrument at all.
| Function | Operation | Modern analogue |
|---|---|---|
| Manas | Receives sensory input; oscillates in Sankalpa-Vikalpa — proposing and doubting | Sensory processing and working attention |
| Buddhi | Determines, decides, discriminates (nishchayatmika) | Executive function and judgement |
| Ahamkara | Appropriates experience as "I" and "mine" (abhimana) | Self-referential processing |
| Chitta | Stores impressions (Samskaras); the reservoir from which memory arises | Long-term memory and implicit learning |
Section 3.6 covers this model in depth. What matters here is the framing: an instrument can be trained, cleaned and repaired; consciousness needs nothing done to it. That is the whole logic of yoga psychology, and it is what distinguishes it from most Western therapeutic models, which aim to repair a self.
Stages of consciousness
Two schemes are in circulation and the syllabus expects both. They are not the same scheme.
The Western three levels (Freud's topographic model)
| Level | Content | Accessibility |
|---|---|---|
| Conscious | What is in awareness right now | Immediate |
| Subconscious / preconscious | Not currently in awareness but retrievable | Available on recall |
| Unconscious | Repressed material, drives, conflicts | Not directly accessible; inferred from dreams, slips, symptoms |
The standard image is the iceberg: a small conscious portion above the waterline, a vast unconscious below.
The Vedantic four states (Mandukya Upanishad)
| State | Sanskrit | Experiencer | Field |
|---|---|---|---|
| Waking | Jagrat | Vishva / Vaishvanara | Gross objects, outward-turned |
| Dream | Svapna | Taijasa | Subtle impressions, inward-turned |
| Deep sleep | Sushupti | Prajna | Undifferentiated; blissful but unaware |
| The Fourth | Turiya | — | Non-dual; the substrate of the other three |
Why the two schemes are not equivalent
This is the discrimination an examiner is testing:
- Freud's levels are contents of one mind sorted by accessibility. The Mandukya's states are modes of consciousness itself.
- Freud's unconscious is a repository of what was pushed down. Sushupti is not a repository; it is a state entered nightly by everyone.
- Freud has no fourth. Turiya has no Western analogue in that model at all — it is not a deeper layer of content but what is present in and as all three states.
Mapping Sushupti onto "the unconscious" is the standard error, and it is wrong in both directions.
The cognitive process
Cognition (Latin cognoscere, to know) is the set of processes by which knowledge is acquired, stored, transformed and used.
The stages
| Stage | What happens | Yogic counterpart |
|---|---|---|
| 1. Sensation | A stimulus is registered by a sense organ | The Jnanendriyas contacting their Tanmatras |
| 2. Attention | Selection of a portion of the sensory field | Dharana is trained attention |
| 3. Perception | The selected input is organised and interpreted; meaning is assigned | Pramana if accurate; Viparyaya if not |
| 4. Memory | Encoding, storage, retrieval | Smriti (PYS 1.11); the store is Chitta, the contents Samskaras |
| 5. Thinking | Manipulation of representations; concept formation, problem solving | Vikalpa where the content is verbal and objectless |
| 6. Reasoning | Drawing inferences — deductive and inductive | Anumana, the second Pramana |
Nature of the cognitive process
It is active, not passive: perception constructs rather than records. It is selective — attention is a bottleneck, and most of the sensory field is discarded. It is constructive — memory reconstructs rather than replays, which is why it is systematically unreliable. And it is affected by state: fatigue, emotion and arousal all measurably degrade it.
That last point is where yoga's contribution lies. Yoga does not add cognitive capacity; it removes the conditions that degrade it. Reducing Vikshepa improves attention; reducing sympathetic arousal improves working memory; reducing rumination frees processing capacity.
The convergence with Patanjali's Pramanas
| Cognitive psychology | Patanjali (PYS 1.7) | Example |
|---|---|---|
| Direct experience | Pratyaksha — perception | Seeing the flame |
| Inference | Anumana — reasoning from evidence | Smoke on the hill implies fire |
| Testimony | Agama / Shabda — reliable verbal authority | A trustworthy report or scripture |
Patanjali also names the failure modes, which cognitive psychology arrived at much later: Viparyaya (misperception — rope taken for a snake, the ancestor of the modern study of perceptual illusion) and Vikalpa (verbal construction with no object — the ancestor of the study of language-driven belief).
Summary of Exam-Key Points
- Psychology = psyche + logos; today, the scientific study of behaviour and mental processes. Wundt, Leipzig, 1879.
- Antahkarana Chatushtaya: Manas, Buddhi, Ahamkara, Chitta — subtle matter, not consciousness.
- Freud's three levels: conscious, subconscious/preconscious, unconscious — sorted by accessibility.
- Mandukya's four states: Jagrat, Svapna, Sushupti, Turiya — modes of consciousness. Sushupti ≠ the unconscious.
- Cognitive stages: sensation → attention → perception → memory → thinking → reasoning.
- Three Pramanas (PYS 1.7): Pratyaksha, Anumana, Agama; failure modes Viparyaya and Vikalpa.
