1.) With the two-point threshold as a task, how would you demonstrate the method of limits? A two-point threshold is the point where the perception of 2 points touching the skin changes from one point perceived to 2. In order to demonstrate this using the method of limits I would have a volunteer participant close their eyes and hold out their arm. Then using a 2 pointed compass, I would put the points as close together as they can go and begin the task. I would touch the points to the person’s forearm and ask if it felt like one or two separate touches from the needles. Gradually, I would increase the distance between the needles of the compass in small increments. When it gets to the point that the participant begins to notice two separate …show more content…
touches, I would stop. This would be considered the ascending trial. For the descending trial I would set the 2 pointed compass needles to just above threshold, and begin the process again in reverse order until the perception of just one needle touch is perceived instead of 2. -Erica Trujillo 2.) Make up some numbers to show that you understand how Donders’ subtraction method was used in the reaction time research in Wundt’s lab. DRT- SRT 0.39(DRT)- 0.14(SRT) = 0.25 (discrimination time) . - Kelly Haverfield 3.) Make up some numbers to show that you understand how Ebbinghaus used the method of savings in his memory research.
It took me 30 minutes to learn to drive my dad’s car. Once I tried to relearn this, it took me 10 minutes. (30 min - 10 min) = 20 minutes, (20 min / 30 total min.)*(100) = 66.66% saved - Aylin Rodriguez 4.) In a nonsense syllable study, describe how you would study retroactive inhibition. The idea of retroactive inhibition is when new memory interferes with old memory, for example if you were to call your ex lover your new lovers name … the new lovers name retroactively interferes with the old lovers causing accidental recall. However, the name of lovers or ex lovers is too meaningful to use in a nonsense syllable study. Therefore, If I were to study retroactive inhibition in a nonsense syllable study, I would first give participants two lists with words that have no meaning in relation to each other or themselves. Then, I would tell participants to memorize the first list and between the learning of that first list, tell them to memorize a second list. Then, ask them to recall the words of the first list, if they only remember the words from the second list that will show that the learning of the second list interfered with the relearning of the first list because that memory of the second list was more recent. -Casey

Results: The experiments required the starting, ending, and total times of each run number. To keep the units for time similar, seconds were used. An example of how to convert minutes to seconds is: 2 "minutes" x "60 seconds" /"1 minute" ="120" "seconds" (+ number of seconds past the minute mark)
The first study I reviewed was “Creating False Memories: Remembering Words Not Presented in Lists” by Roediger III and Kathleen B. McDermott. The study was published in 1995, in the Journal of Experimental Psychology: Learning, Memory & Cognition. Roediger and McDermott conducted two separate experiments in their study. The experiments were modeled after Deese’s 1959 study “On the Prediction of Occurrences of Particular Verbal Intrusions in Immediate Recall.” The results of Deese’s study concluded that participants falsely recalled a nonpresented critical lure 44% of the time. 36 students from Rice University participated in Roediger and McDermott’s first experiment. The students participated as part of a course project. The participants were presented with six lists that were developed from Deese’s study and Russell and Jenkins 1954 study “The complete Minnesota norms for responses to 100 words from the Kent-Rosanoff word association Test.” The six lists that were chosen for the Roediger and McDermott study were shown to elicit high rates of false recall in Deese’s study. The list contained 12 associated words that related to one nonpresented word. An example nonpresented word is chair, the 12 associated w...
Ebbinghaus used nonsense syllables to demonstrate this experiment. Nonsense syllables are three letter combinations usually consisting of a consonant-vowel-consonant combination. These combinations which included some 2300, were not word and therefore did not make sense, hence the term "nonsense." He used these so-called nonsense syllables in order to discourage how the prior existence of the meanings may influence learning of the present. He used nonsense syllables in order to prevent complications in the experiment and its results.
False memories being created is obvious through many different ways, such as eye-witness testimonies and past experiments that were conducted, however repression is an issue that has many baffled. There seems to be little evidence on the factual basis of repressed memories, and many argue that it does not exist. The evidence for repression in laboratories is slowly emerging, but not as rapidly as the evidence for false memories. It has been hard to clinically experiment with repressed memories because most memories are unable to be examined during the actual event to corroborate stories. Experimenters are discovering new ways to eliminate this barrier by creating memories within the experiment’s initial phase. This is important for examining the creation of false memories during the study phase. This research study will explore the differences between recovered memories and false memories through research and experiments. Other terms and closely related terms will be discussed, while examining any differences, in relation to repressed memories. The possibility of decoding an actual difference between recovered memories and false memories, through biological techniques. Because false memories can be created, examining these creations in a laboratory setting can shed light on facts overlooked. Exploring these issues will also help with the development of better therapeutic techniques for therapists in dealing with memories. This can lead to an easier process for patients and therapists if they must go through the legal system in relation to an uncovered memory.
These studies tend to use word completion tasks to differentiate between implicit and explicit memory. Word-stem completion tasks are typically used to employ the implicit memory. The participant is presented with a word completion task and the participant can fill in the missing letters to form any word they choose. The implicit memory is one that is used involuntarily and unconsciously.
Many of the memories that were remembered are usually previous childhood experiences. Dewhurst and Robinson (2004) conducted a study where 5, 8 and 11 year old children were tested on memory illusion. One of the procedures used to test false memories is the DRM paradigm. The DRM paradigm presents a list of words that include a critical word that is typically remembered although it was never presented. During the DRM procedure the children were given five lists that contained eight words. Each list consisted of at least one rhyme and a semantic theme. Each child was tested on their own by the classroom

Amnesia, a severe long-term memory loss disease, is caused by damaged brain tissue. There are two different types of amnesia. Retrograde amnesia is also known as backward moving. This is when you have a hard time remembering the past, especially episodic memories. This occurs because of memory consolidation. Memory consolidation is the process of a new memory setting until it becomes permanently in the brain. If this process is disrupted, the memory may be lost (Hockenberry and Hockenberry page 265). Anterograde amnesia is also known as forward moving. This is when you are unable to form new
If a three-year-old child can practice riding the backward brain bike and achieve it in two weeks. Why shouldn’t an adult be able to do the something in two week? His son did have an incentive for practicing to ride the bicycle; he was promised by his dad (Destin), that he would let him meet an astronaut. Destin decided to test himself by getting on an ordinary bicycle to see if he could ride it; he was shocked to see that he could not. He ends up having to retrain himself to learn how to ride an ordinary bicycle, which took about twenty minutes to do.
Sensory limits and thresholds: The human sensory organs have nerves, which respond to different forms of energy they receive in different ways. For instance, the eyes receive light rays and convert them into electrical energy. The electrical energy is transmitted to the brain creating the sensation of vision leading to perception. Each sense receptor needs a minimum level of energy for perception to take place. This level is called the absolute threshold, which refers to the point below which sensory organs do not perceive energy. The differential threshold is the minimum amount by which two like stimuli should differ in order to be perceived as distinct. Therefore, sensory limits and differential threshold affect the perception

As a young kid I was constantly intrigued by what he was doing. My mom could never seem to keep track of me because I would sneak off to go see what my dad was fixing. The next thing you know I was holding a flashlight for him. This became my new job for years to come, I may as well have had a name tag that said flash light holder because I couldn’t do anything else. As I got older and got my first car, I started to learn how they operate and the engineering behind cars. I began doing oil changes, rotating tires, brakes, and many other little things I learned about on my first car. Around this time, I got a small job to start making some
