It is also possible for us to get messages that are presented below the threshold for conscious awareness-these are called subliminal messages. Under quiet conditions, the hair cells (the receptor cells of the inner ear) can detect the tick of a clock 20 feet away (Galanter, 1962). It has been estimated that on a clear night, the most sensitive sensory cells in the back of the eye can detect a candle flame 30 miles away (Okawa & Sampath, 2007). ![]() The sensitivity of our sensory receptors can be quite amazing. ![]() Another way to think about this is by asking how dim can a light be or how soft can a sound be and still be detected half of the time. Absolute threshold refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time. The sensitivity of a given sensory system to the relevant stimuli can be expressed as an absolute threshold. We also have sensory systems that provide information about balance (the vestibular sense), body position and movement (proprioception and kinesthesia), pain (nociception), and temperature (thermoception). It turns out that this notion of five senses is oversimplified. You have probably known since elementary school that we have five senses: vision, hearing (audition), smell (olfaction), taste (gustation), and touch (somatosensation). The conversion from sensory stimulus energy to action potential is known as transduction. These cells relay messages, in the form of action potentials (as you learned when studying biopsychology), to the central nervous system. For example, light that enters the eye causes chemical changes in cells that line the back of the eye. When sensory information is detected by a sensory receptor, sensation has occurred. What does it mean to sense something? Sensory receptors are specialized neurons that respond to specific types of stimuli. Discuss the roles attention, motivation, and sensory adaptation play in perception.Describe the concepts of absolute threshold and difference threshold.Distinguish between sensation and perception.This movie is available on iTunes and Amazon.By the end of this section, you will be able to: Lastly, this product comes with a complete teacher key. I have also included a character reference guide and some "fact vs. The video guide is time stamped, which allows teachers to chunk the movie into parts and to easily pick up where the class left off. This product includes 32-questions to help keep your students focused and engaged throughout the movie. It's a must-see for anyone interested in history, space exploration, and the fight for equality. Overall, Hidden Figures is an inspiring and important film that celebrates the resilience and brilliance of these women, as well as the power of determination and perseverance. The movie is a tribute to their achievements and the contributions of African American women to the space program and the STEM field. ![]() The film also highlights the impact of the Civil Rights Movement on the women's lives, as they navigate segregation and discrimination in their personal and professional lives. Jackson, played by MonĂ¡e, becomes NASA's first black female engineer, breaking through multiple barriers and fighting for her right to attend an all-white school to obtain her degree. ![]() Vaughan, played by Spencer, becomes the supervisor of a group of "computers," women who manually do the calculations needed for the space program, and she teaches herself and her team how to program IBM computers. Katherine Johnson, portrayed by Henson, is a brilliant mathematician who becomes a crucial member of the team responsible for calculating the trajectory for John Glenn's historic orbit around the Earth. Despite facing racial and gender discrimination, the women use their intelligence and determination to break through barriers and make significant contributions to the space program. The film follows the lives of Katherine Johnson, Dorothy Vaughan, and Mary Jackson, who work as mathematicians at NASA's Langley Research Center in Virginia. The film is based on the true story of three African-American women who played key roles in NASA's Space Race during the 1960s.
