COGS 200 Perception Philosopy with correct answers 100% 2026 The structure of a common model of a cognitive system. - Correct Answer Knowledge representation (data structures, memory) and reasoning (algorithm, computation) are central. • Perception forms one boundary (or point of contact) between the agent and her environment. • Behaviour (action) forms the other boundary. interfaces are peripheral, inessential to who we are what do those boundaries and interfaces reflect - Correct Answer These boundaries or interfaces reflect, to some degree, the isolation of the system from its environment, although the system is, of course, causally connected to that environment, too The Classical Sandwich Model Susan Hurley (2001) "Perception and Action" - Correct Answer • The agent is distinct from, but interacts with, its environment. close causal contact with environment, if not in causal contact no perception (?) • World-engaging processes, input and output, provide two different kinds of interface between the agent and its environment. agent = cognitive system agent receives sensory input from environment, thinks, and acts intelligently, helpfully, successfully on environment, changing environment look at diagram Human Cognitive Systems • Inside "the black box": the mind and its activity: 4 main features - Correct Answer • Representational and rational, consciously acquiring, processing, retaining, and employing information (knowledge representations). • Unified in a way that constitutes a "point of view" or "subject of experience." • Private, not public. Difficult to investigate empirically. Stimulus and response are no more than evidence for internal cognitive activity. • Free and autonomous, creative, and morally significant Human Cognitive Systems • Knowledge representations and reasoning: examples - Correct Answer • Memories, beliefs, desires, mental images, intentions, etc. • Rational processes according to which these states are manipulated and ultimately produce intelligent behaviour look at examples of sandwich model - Correct Answer adaptation cycle, look at diagram - Correct Answer person is environment yellow is cognitive system cognitive system is using blue box to make model of environment in peach box it gives you help that is useful based on what it knows intelligent agents in the world diagram - Correct Answer The Purpose of Perception - Correct Answer • To provide us with experiences (how things look or seem) that are (mostly?) accurate representations of the scene before us. 1. We encounter objects in various arrangements. 2. These encounters produce perceptual experiences in us that represent our environment. 3. We form perceptual beliefs (knowledge representations) on the basis of these experiences and how we interpret them. The Stages of Perception • Perception seems very likely to be a process that takes place in stages., what are these stages - Correct Answer 1. Scenes → 2. Experiences → 3. Beliefs 1 → 2 My encounter with the scene produces perceptual experiences ("sensations"). 2 → 3 These perceptual experiences lead to perceptual beliefs ("perceptions") could be visual experience, if they are acceptable to us, fit what we know, produce beliefs about how the world is what is perceiver - Correct Answer A perceiver is something like a scientist gathering data through different modalities, processing that data, and coming to a conclusion about what is out there in the scene before her (a "theory" of the scene, based on her "data"). "inverse problem" - Correct Answer the problem of reconstructing the structure of a novel, changing, external world from the data that we receive from that world."
