Introduction to Cognitive Psychology

2.0K
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

378
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Area of Science:

  • Terahertz (THz) communication technology
  • Wireless networking
  • Signal processing

Background:

  • The THz Torch wireless link technology, while low-cost, faced limitations in range and bit rate due to hardware constraints.
  • Existing hardware imposed thermal time constant constraints on emitters and sensors, hindering performance.
  • Previous operational figures of merit (Range × Bit Rate) were modest.

Purpose of the Study:

  • To improve the bit error rate (BER) performance of the THz Torch wireless link technology.
  • To enhance the 'Cognitive Demodulation' technique for terahertz communication.
  • To demonstrate practical advancements enabling field trials.

Main Methods:

  • Introduction of 'Cognitive Demodulation' to bypass thermal time constant limitations.
  • Development and integration of novel software techniques to enhance Cognitive Demodulation.
  • Implementation of hardware improvements for real-world deployment and field trials.

Main Results:

  • Achieved over a 100-fold BER improvement in laboratory settings and a 60-fold improvement in non-laboratory environments.
  • Demonstrated a maximum operational range of 2 meters at 125 bits per second (bps).
  • Increased demodulation speed by nearly 10,000 times, enabling real-time processing and reducing future hardware demands.

Conclusions:

  • Enhanced Cognitive Demodulation software significantly boosts BER performance and speed for THz Torch wireless links.
  • Hardware advancements and software improvements have enabled successful field trials in an office corridor.
  • The technology shows promise for practical, low-cost terahertz wireless communication systems.
