SHORT NOTES :-

QUESTION 1 :- Information processing models with reference to comparison with computers and as connectionism views

Introduction:

     The comparison between human memory and computer functioning is like exploring the intricate dance of mind and machine. Just as computers process information in a structured manner, our minds too follow a model known as information processing. However, this model is not the only lens through which we can understand memory; connectionism, another perspective, delves into the complex web of neural networks that shape our memories. In this exploration, we will unravel the similarities and differences between human memory and computers through the information processing model, and then venture into the interconnected world of connectionism.

1. Information Processing Model: Imagine your brain as a computer, going through three main steps to handle information: encoding, storage, and retrieval. Encoding is like typing on a keyboard; it converts sensory input into a form the brain can understand. Storage is akin to saving a document; it holds onto the information for future use. Retrieval is like searching for a file on your computer; it brings back stored information when needed.
However, our human memory is a bit fuzzy and delicate compared to the robust stability of computer memory. Our memories can blur around the edges, and they are susceptible to fading over time. Unlike computers, our brains engage in parallel processing, tackling multiple tasks simultaneously. Moreover, our memory is dynamic, constantly evolving, and adapting, unlike the static nature of computer memory.
2.Connectionism: Now, let’s dive into the world of connectionism, a model that views memory as the result of interconnected neural networks in our brains. Think of these networks as intricate spiderwebs of connections between neurons. Every time we learn something new, these connections change, forming and strengthening pathways for future learning. It’s like a beautiful dance of information flowing through the interconnected corridors of our minds.

Conclusion:

      The comparison between human memory and computers unveils the fascinating intricacies of the information processing model and the connectionist perspective. While the information processing model draws parallels between our brains and computers, it also highlights the nuanced differences, such as the dynamic and parallel nature of human memory. On the other hand, connectionism provides a captivating view of memory as a product of constantly evolving neural networks. Understanding these models not only sheds light on the complexities of memory processes but also emphasizes the uniqueness of the human mind.

QUESTION 2 :- Sensory memory

Introduction:

             Sensory memory is like a quick snapshot of the world around us, capturing sights, sounds, smells, tastes, and touches in their raw form. It’s the brain’s way of temporarily holding onto this information, giving us a brief moment to decide what’s important before it fades away. Let’s delve into the world of sensory memory to understand its types, functions, and importance in how we perceive and interact with our environment.

Definition of Sensory Memory:

          Sensory memory is our brain’s instant recording of sensory information as it comes in, without any processing. Imagine it as a quick flash of light, capturing everything around us in a split second. It’s the very first form of memory we experience, helping us make sense of the world.

A. Types of Sensory Memory:

  1. Iconic Memory: Iconic memory is like a mental photo album, holding onto visual images for a very short time. It’s why we can remember a lightning-fast glimpse of a passing car or a fleeting glance at a sunset. George Sperling’s experiment showed how quickly these visual memories fade, like trying to catch a firefly before it disappears into the night.
  2. Echoic Memory: Echoic memory is our brain’s way of holding onto sounds for a brief moment. It’s why we can recall a snippet of a song or repeat a sentence just after hearing it. It’s like an echo bouncing around in our minds, giving us a chance to process what we’ve heard before it vanishes.

B. Functions of Sensory Memory:

  1. Filtering Incoming Stimuli: Sensory memory acts as a filter, preventing us from being overwhelmed by the constant stream of sensory information bombarding our senses. It holds onto this data briefly, giving us time to decide what’s worth paying attention to.
  2. Buying Time for Further Processing: Think of sensory memory as a traffic light, briefly stopping incoming information to give our brain time to process it. It’s like pressing pause on a video, allowing us to decide whether to hit play and dive deeper into the memory.
  3. Stabilizing Our Perception: Iconic memory helps stabilize our visual world, ensuring that it doesn’t flicker and blur with every movement. Echoic memory aids in recognizing and understanding speech, ensuring that we can follow conversations and respond appropriately.

  Conclusion:

          Sensory memory is the brain’s quick snapshot of the world around us, capturing sensory information in its raw form before it’s processed further. It helps us make sense of our environment, giving us a brief window to decide what’s important. By understanding sensory memory, we gain insight into how we perceive and interact with the world, laying the foundation for further memory formation and cognitive processes.

  Definition of Short-Term Memory:

            Short-term memory is like a temporary storage unit in our brain, holding onto a small amount of information for a short time. It’s the mental workspace where we juggle ideas, numbers, and words before either discarding them or moving them to long-term memory.

  A. Capacity and Duration:

  1. Capacity: Short-term memory isn’t limitless; it’s more like a small backpack than a warehouse. According to Miller’s Magic Number 7 ± 2, we can hold around 5 to 9 items in our short-term memory at once. However, this capacity can vary depending on factors like age and cognitive abilities.
  2. Duration: Information in short-term memory doesn’t stick around forever. Without active rehearsal, it can fade away like a whisper in the wind, lasting only a few seconds to half a minute. It’s why we forget a phone number moments after hearing it if we don’t repeat it to ourselves.

  B. Functions of Short-Term Memory:

  1. Temporary Storage: Short-term memory acts as a temporary storage system, holding onto information that we’re actively using. It’s like a mental sticky note, keeping track of things just long enough for us to finish our current task.
  2. Immediate Cognitive Tasks: Think of short-term memory as the mental workspace where we solve puzzles, make decisions, and understand complex ideas. It’s like the scratchpad where we jot down calculations or ideas before transferring them elsewhere.
  3. Attention and Rehearsal: Short-term memory requires our attention and rehearsal to keep information fresh. It’s like a revolving door; if we don’t actively keep information circulating, it quickly slips away.

  C. Experimental Evidence:

               An experiment by Lloyd Peterson and Margaret Peterson, participants were asked to remember consonant groups while being prevented from rehearsing them. The results showed that information in short-term memory decays rapidly without active processing, highlighting its limited duration.

  D. Relationship with Working Memory:

               Working memory is like the evolved cousin of short-term memory, emphasizing not just storing information temporarily but also actively manipulating it. It’s like the conductor orchestrating a symphony of thoughts, integrating information from short-term and long-term memory for complex cognitive tasks.

    Conclusion:

             Short-term memory is the unsung hero of our cognitive processes, allowing us to hold onto information briefly as we navigate the complexities of everyday life. By understanding its capacity, duration, and functions, we gain insight into how our minds work in real-time. Short-term memory isn’t just a fleeting moment in our mental landscape; it’s a fundamental building block of cognition, paving the way for deeper understanding and learning.
