Perception Since the rise of experimental psychology in the 19th Century, psychology's understanding of perception has progressed by combining a variety of techniques.[3] Psychophysics quantitatively describes the relationships between the physical qualities of the sensory input and perception.[5] Sensory neuroscience studies the brain mechanisms underlying perception. Perceptual systems can also be studied computationally, in terms of the information they process. Perceptual issues in philosophy include the extent to which sensory qualities such as sound, smell or color exist in objective reality rather than in the mind of the perceiver.[3] The perceptual systems of the brain enable individuals to see the world around them as stable, even though the sensory information is typically incomplete and rapidly varying. Human and animal brains are structured in a modular way, with different areas processing different kinds of sensory information. Process and terminology[edit] Perception and reality[edit]
Memory Definition & Types of Memory For us to recall events, facts or processes, we have to commit them to memory. The process of forming a memory involves encoding, storing, retaining and subsequently recalling information and past experiences. Cognitive psychologist Margaret W. Matlin has described memory as the “process of retaining information over time.” When they are asked to define memory, most people think of studying for a test or recalling where we put the car keys. The process of encoding a memory begins when we are born and occurs continuously. Important memories typically move from short-term memory to long-term memory. Motivation is also a consideration, in that information relating to something that you have a keen interest in is more likely to be stored in your long-term memory. We are typically not aware of what is in our memory until we need to use that bit of information. Implicit memory is sometimes referred to as unconscious memory or automatic memory.

Thought Cognitive process independent of the senses In their most common sense, the terms thought and thinking refer to conscious cognitive processes that can happen independently of sensory stimulation. Their most paradigmatic forms are judging, reasoning, concept formation, problem solving, and deliberation. But other mental processes, like considering an idea, memory, or imagination, are also often included. These processes can happen internally independent of the sensory organs, unlike perception. But when understood in the widest sense, any mental event may be understood as a form of thinking, including perception and unconscious mental processes. Various types of thinking are discussed in the academic literature. Definition[edit] The word thought comes from Old English þoht, or geþoht, from the stem of þencan "to conceive of in the mind, consider".[21] Theories of thinking[edit] Various theories of thinking have been proposed.[22] They aim to capture the characteristic features of thinking.
What Is Memory? - The Human Memory Memory is our ability to encode, store, retain and subsequently recall information and past experiences in the human brain. It can be thought of in general terms as the use of past experience to affect or influence current behaviour. Memory is the sum total of what we remember, and gives us the capability to learn and adapt from previous experiences as well as to build relationships. It is the ability to remember past experiences, and the power or process of recalling to mind previously learned facts, experiences, impressions, skills and habits. It is the store of things learned and retained from our activity or experience, as evidenced by modification of structure or behaviour, or by recall and recognition. Etymologically, the modern English word “memory” comes to us from the Middle English memorie, which in turn comes from the Anglo-French memoire or memorie, and ultimately from the Latin memoria and memor, meaning "mindful" or "remembering".
Mental process A specific instance of engaging in a cognitive process is a mental event. The event of perceiving something is, of course, different from the entire process, or capacity of perception—one's ability to perceive things. In other words, an instance of perceiving is different from the ability that makes those instances possible.

Drawing from actual perceptions, imagination employs intricate conditional processes that engage both semantic and episodic memory to generate new or refined ideas.[6] This part of the mind helps develop better and easier ways to accomplish tasks, whether old or new. The English word "imagination" originates from the Latin term "imaginatio," which is the standard Latin translation of the Greek term "phantasia." The Latin term also translates to "mental image" or "fancy."
A workout for working memory People may be able to remember a nearly infinite number of facts, but only a handful of items--held in working memory--can be accessed and considered at any given moment. It's the reason why a person might forget to buy an item or two on a mental grocery list, or why most people have difficulty adding together large numbers. In fact, working memory could be the basis for general intelligence and reasoning: Those who can hold many items in their mind may be well equipped to consider different angles of a complex problem simultaneously. If psychologists could help people expand their working-memory capacity or make it function more efficiently, everyone could benefit, from chess masters to learning-disabled children, says Torkel Klingberg, MD, PhD, an assistant cognitive neuroscience professor at the Karolinska Institute in Sweden. "It could be that working-memory problems give rise to observable behavioral symptoms of ADHD: distractibility and also poor academic achievement," she says.
Cognitive science Cognitive science is the interdisciplinary scientific study of the mind and its processes.[1] It examines what cognition is, what it does and how it works. It includes research on intelligence and behavior, especially focusing on how information is represented, processed, and transformed (in faculties such as perception, language, memory, reasoning, and emotion) within nervous systems (human or other animal) and machines (e.g. computers). Cognitive science consists of multiple research disciplines, including psychology, artificial intelligence, philosophy, neuroscience, linguistics, and anthropology.[2] It spans many levels of analysis, from low-level learning and decision mechanisms to high-level logic and planning; from neural circuitry to modular brain organization. The fundamental concept of cognitive science is "that thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structures Principles[edit] "...
Finding Activities for Parents With Memory Loss - The New York Times I’ve invited the clinical psychologist Cynthia Green, an assistant clinical professor of psychiatry at Mount Sinai Medical Center in New York and the author of several books on memory (including “Through the Seasons: An Activities Book for Memory Challenged Adults and Caregivers“), to join the conversation today. I’ve been hearing laments about the difficulties of visiting relatives with dementia; people yearn to make that time together enjoyable and meaningful, but they can’t always figure out how to connect. Dr. — Paula Span When someone we love receives a diagnosis of memory loss, we fall headfirst into the (usually) unasked-for role of manager, overseeing both the major decisions — whether a move is necessary, for example — as well as the minor, everyday ones. Dr. Yet once the dust has settled and we’ve established a routine, we face a different problem. Shouldn’t we be doing something with them? The trick is to find activities that are engaging yet doable. Plan your approach.
