Learning goals for the course

Question 1

The historical background for the modern philosophy of science (1900s onwards)

Answer 1

Dualism, Empiricism and Idealism

Question 2

Understand what is/was regarded as justified beliefs

Answer 2

Analytic, synthetic, a priori, a posteriori

Question 3

Understanding of how science and
pseudoscience can be differentiated, using
creationism and evolutionary theory as examples
(The demarcation problem)

Answer 3

The demarcation problem tackles how to differentiate science from pseudoscience.

Science relies on testing and explaining the natural world through evidence, while pseudoscience often lacks these qualities.

For instance, creationism, which asserts divine creation, falls into pseudoscience, whereas evolutionary theory is scientific, being based on empirical evidence and testability.

Question 4

Understanding some of the vulnerabilities of our
own field – the importance of good practices,
using precognition research as an example

Answer 4

Certain practices or beliefs can lead to pseudoscience rather than genuine scientific inquiry.

Precognition, the supposed ability to predict future events, is often considered untestable and lacks empirical evidence to support its claims.

Question 5

Understanding how logical positivism separates
meaningful from meaningless sentences

Answer 5

Logical positivism distinguishes meaningful from meaningless sentences based on empirical verifiability and logical coherence.

Meaningless statements lack empirical grounding or violate logical principles.

Protocol sentences, reflecting direct observations, are deemed meaningful.

Theoretical statements must derive from or be testable against observations to be considered meaningful.

Question 6

Understanding the problems facing logical positivism, e.g.
verification of general sentences and the Quine-Duhem
thesis

Answer 6

Logical positivism faces difficulties when trying to verify general statements, such as theoretical ones, using only observational evidence.

The Quine-Duhem thesis further complicates this by suggesting that when a theory fails to match observations, it’s not always clear which part of the theory is at fault, as multiple interconnected assumptions are involved.

Question 7

Understanding the induction problem

Answer 7

The “induction problem” refers to the challenge of justifying the process of drawing general conclusions from specific observations.

It’s about how we can make reliable predictions or generalizations about the world based on past experiences.

Question 8

Understanding how falsification follows deductive
procedures

Answer 8

Falsification, which involves attempting to prove a theory wrong rather than confirming it, fits into deductive logic, where the truth of conclusions is guaranteed by the truth of premises.

(Karl popper)

Question 9

Understanding how Popper understands
falsifiability as a characteristic that separates
scientific from non-scientific statements (solves the
demarcation problem)

Answer 9

Popper’s idea that scientific statements should be open to falsification through empirical testing.

Scientific theories should make predictions that can be tested against observations, and if those predictions are proven false, it indicates that the theory is flawed or incomplete.

Question 10

Understanding Kuhn’s idea of paradigms and
paradigm shifts

Answer 10

Paradigm Shifts: These occur when there’s a fundamental change in the prevailing scientific framework, often catalyzed by significant revolutions or breakthroughs.

Holism and Perception: Kuhn’s notion of holism suggests that our understanding of the world is holistic, shaped by the theoretical frameworks and paradigms we subscribe to.

Question 11

Understanding why paradigms may be
incommensurable

Answer 11

Incommensurability: This concept suggests that paradigms are not directly comparable or commensurable because they entail different underlying assumptions, methods, and ways of interpreting phenomena.

Question 12

Capability to reflect on what amounts to truth

Answer 12

Different paradigms influence our perception of truth in these disciplines.

E.g. The Millikan oil drop experiment and the cognitive revolution

Question 13

Understanding how behaviourism is an externalist paradigm

Answer 13

In behaviorism, being an externalist paradigm means focusing solely on observable behavior and its relationship with the environment.

This approach disregards internal mental states and emphasizes controlling the environment to explain, predict, and control behavior.

Behaviorism operates on the premise that behavior is a response to stimuli, and understanding and influencing behavior requires manipulating external factors rather than delving into the mind’s inner workings.

Question 14

Understanding what operant conditioning is, and how it
differs from classical conditioning

Answer 14

Operant conditioning focuses on how behavior is shaped by its consequences, such as reinforcement or punishment, without considering inner mental processes.

Classical conditioning deals with involuntary responses triggered by stimuli, where associations are formed between stimuli and responses.

Question 15

Understanding the connection to empiricism and logical
positivism

Answer 15

Behaviorism asserts that the proper study of the mind is the study of behavior, which can be understood as operations on the environment. This aligns with empiricism.

Logical positivism stresses intersubjective and external verification, denying the significance of inner states.

Question 16

Being able to critically reflect on the assumptions of
behaviourism

Answer 16

Critics, like Dennett, argue against behaviorism’s dismissal of inner causes, suggesting that it oversimplifies complex behaviors and ignores cognitive processes.

Question 17

Being able to see how behaviourism is still relevant today

Answer 17

It provides practical methods for understanding and modifying behavior, applicable in various fields such as education, therapy, and organizational management.

It continues to shape psychological research and applications,

Question 18

Understanding the intellectual history leading to the
cognitive revolution

Answer 18

The intellectual history leading to the cognitive revolution is characterized by the dominance of behaviorism

Behaviorism, influenced by empiricism and logical positivism, advocated for the study of behavior as operations on the environment and focused on predicting and controlling behavior without delving into inner states.

Question 19

Understanding the assumptions of
computationalism

Answer 19

Cognition as Computation: The core assumption is that cognitive processes can be understood as computations on mental representations.

Implementation Independence: Computationalism assumes that computation is independent of the hardware it runs on.

Systematically Interpretable Symbol Manipulation: Computation, within the framework of computationalism, involves symbol manipulation following strict syntax rules.

Question 20

Understanding what (mental) representations are

Answer 20

Mental representations refer to the internal structures or symbols that the mind uses to represent external stimuli, concepts, or knowledge

Question 21

Understanding David Marr’s three levels of analysis

Answer 21

Computational Theory: This level deals with understanding the goal of the computation, why it’s appropriate, and the logic behind the strategy used to achieve it.

Representation and Algorithm: At this level, the focus is on implementing the computational theory. It addresses questions like what representation is used for the input and output, and what algorithm is employed for the transformation.

Hardware Implementation: This level concerns itself with realizing the representation and algorithm physically.

Question 22

Understanding the impact of the Chinese Room
Argument

Answer 22

This argument raises questions about whether computational processes alone can account for genuine understanding and consciousness.

Searle presents a scenario where a person who does not understand Chinese is inside a room, receiving Chinese symbols and producing responses according to a rule book. Despite appearing to understand Chinese to an outside observer, the person inside the room does not actually comprehend the language.

Question 23

Understanding the Symbol Grounding Problem

Answer 23

The Symbol Grounding Problem refers to the challenge of understanding how symbols, such as those used in language or computation, acquire their meanings.

The problem: Explaining how these symbols come to represent real-world objects, concepts, or events. (Grounding in real life)

Question 24

Understanding the different levels of Turing
indistinguishability

Answer 24

The different levels of Turing indistinguishability refer to the ability of a computational model to mimic human cognitive processes to such an extent that it cannot be distinguished from human cognition.

T1: Basic simulation with limited resemblance to human behavior.
T2: Improved simulation with some nuanced aspects of cognition.
T3: Advanced simulation closely resembling human cognition in various tasks.
T4: Virtually indistinguishable from human cognition, with high-level capabilities.

Question 25

Ability to critically reflect on the scope of the Chinese Room argument

Answer 25

Implications on the Symbol Grounding Problem and Turing indistinguishability: Chinese Room targeting limited functional mimicry (T2). Whole-room-argument: Understanding might emerge from the system as a whole or through causal interaction with the world.

Question 26

Understanding the limitations of the computationalist paradigm seen from the connectionist paradigm

Answer 26

Neural network dynamics over internal computation and questions the independence of algorithmic and implementation levels. Connectionism prioritizes empirical evidence over imagination in understanding AI capabilities. Advantages such as speed and flexibility in addressing contextual challenges.

Question 27

Understanding how neural networks work on a broad level

Answer 27

Neural networks operate as black boxes, taking input data, processing it through layers of interconnected units (neurons), and producing an output. Through training, the network learns to adjust the weights of connections between neurons to minimize the difference between its output and the desired output. This process, called backpropagation, allows neural networks to learn complex patterns and relationships in data without explicit programming.

Question 28

Understanding how semantic content may emerge from the network, i.e. how symbols may get grounded

Answer 28

Semantic content emerges from interconnected units, like neurons, below the representational level in computationalism, where neural networks underlie behaviors attributed to internal computation. Classical AI, exemplified by Shakey the robot, faces challenges representing vision due to slower processing compared to the human brain.

Question 29

Understanding how perception can be seen as inference based on sensory input

Answer 29

Perceptual inference is done following Bayes’ rule. (Prior knowledge)

Question 30

Understanding how action is necessary to select the best inference

Answer 30

Best inference = the inference that minimises prediction error

Question 31

The capability to reflect on the relevance of this for the symbol grounding problem and artificial intelligence

Answer 31

Perception isn't direct but probabilistic, influenced by prior beliefs and current observations. Action refines perception, as exemplified by viewing objects from different angles. Predictive processing emphasizes updating hypotheses based on sensory input.

Question 32

Appreciating how prediction error minimisation may explain mind attributes such as emotion, introspection, privileged access and self

Answer 32

Emotion: PEM suggests emotions arise from the brain's attempt to minimize prediction errors regarding internal states. Introspection: PEM views introspection as inference on mental causes, where the brain tries to understand and predict its own cognitive processes. Privileged Access: Individuals have direct access to their own prediction errors, leading to unique insights into their mental states. The Self: PEM proposes that the self emerges from the brain's construction of a self-model, continually updated based on sensory input and action outcomes.

Question 33

Understanding the difference between access consciousness and phenomenal consciousness

Answer 33

Access consciousness: Mental content availability for cognitive processes. Phenomenal consciousness: Subjective "feel" of experience.

Question 34

Understanding, how we may able to investigate consciousness in cognitive science

Answer 34

Understanding consciousness involves investigating its neural correlates. Techniques like EEG reveal subconscious processing even when participants don't report conscious awareness. For instance, the attentional blink phenomenon demonstrates subconscious processing of stimuli despite participants' unawareness. Philosophical considerations, like Thomas Nagel's "What is it like to be a bat?" emphasize subjective experience and its irreducibility to functional or intentional states.

Question 35

Capability to reflect on how consciousness is seen from the viewpoints of behaviourism, computationalism, connectionism and predictive processing

Answer 35

Behaviourism: Focuses on observable behavior, translating mental processes into actions. Challenges include operationalizing conscious experience for behavioral study. Computationalism: Posits that consciousness is a form of information processing, implementable in any system capable of computation. Questions arise regarding why and how information processing gives rise to subjective experience. Connectionism: Views consciousness as dependent on brain-like structures and distributed networks. However, it raises questions about how such models instantiate conscious experience. Predictive processing: Models consciousness as hierarchical information processing, where perception provides prediction errors to update internal models of the world. Challenges include explaining why subjective experience emerges from such processing.
