Behavior Analysis in Psychology

Behavior Analysis in Psychology More in Theories Behavioral Psychology Cognitive Psychology Developmental Psychology Personality Psychology Social Psychology Biological Psychology Psychosocial Psychology Behavior analysis is rooted in the behaviorist tradition and utilizes learning principles to bring about behavior change. Some branches of psychology strive to understand underlying cognitions, but behavioral psychology is not concerned with mentalistic causes of behavior and instead focuses on the behavior itself. Behavior analysis has robust practical applications in mental health treatment and organizational psychology, particularly when focused on helping children and adults learn new behaviors or reduce problem behaviors. Behavior analysis is often used to build abilities in children and adults with disabilities increase academic skills in school settings, and enhance employee performance. Behavior Analysis Defined Behavior analysis is a science-based on the foundations and principles of behaviorism. Division 25 of the American Psychological Division is devoted to the area of behavior analysis. According to Division 25, the fact that behavior analysis focuses on behavior as a subject makes it unique. The division also explains that this analysis of behavior can occur in three different ways. First, through the experimental investigation of behavior.Secondly, through applied behavior analysis.?? This process involves taking what researchers know about behavior and applying it in individual, social, and cultural contexts.Finally, through the conceptual analysis of behavior. According to Division 25, this addresses the philosophical, historical, theoretical and methodological issues in behavior analysis. Experimental and Applied Behavior Analysis There are two major areas of behavior analysis: experimental and applied. Experimental behavior analysis involves basic research designed to add to the body of knowledge about behavior.Applied behavior analysis,?? on the other hand, is focused on applying these behavior principles to real-world situations. Those who work in the field of applied behavior analysis are interested in behaviors and their relationship with the environment. Rather than focusing on internal states, ABA therapists focus on observable behaviors and utilize behavioral techniques to bring about behavioral change. According to the Behavior Analyst Certification Board: Professionals in applied behavior analysis engage in the specific and comprehensive use of principles of learning, including operant and respondent learning, in order to address behavioral needs of widely varying individuals in diverse settings. Examples of these applications include: building the skills and achievements of children in school settings; enhancing the development, abilities, and choices of children and adults with different kinds of disabilities; and augmenting the performance and satisfaction of employees in organizations and businesses. History Behaviorism?? was largely established through the influential work of three theorists: Ivan PavlovJohn B. WatsonB.F. Skinner Pavlov discovered the conditioning reflex during his studies with dogs, establishing classical conditioning as a learning method. His research demonstrated that an environmental stimulus (i.e. ringing bell) could be used to stimulate a conditioned response (i.e. salivating at the sound of the ringing bell). John B. Watson extended Pavlovs theory to apply to human behavior, publishing his landmark article Psychology as the Behaviorist View It in 1913 and establishing behaviorism as a major school of thought. B.F. Skinner later introduced the concept of operant conditioning in which reinforcement leads to the desired behavior. These concepts continue to play influential roles in behavior analysis, behavior modification, and psychotherapy. Behaviorism was once a very prominent school of thought within psychology, although its dominance began to decline during the 1950s as psychologists became more interested in humanistic and cognitive approaches. However, behavioral techniques are still widely used today in psychotherapy, counseling, education, and even in parenting. Techniques and Strategies Some of the techniques used by behavior analysts include: Chaining: This behavior technique  involves breaking a task down into smaller components. The simplest or first task in the process is taught first. Once that task has been learned, the next task can be taught. This continues until the entire sequence is successfully chained together.Prompting: This approach involves using some type of prompt to trigger the desired response. This might involve issues a verbal cue, such as telling the person what to do, or a visual cue, such as displaying a picture designed to cue the response.??Shaping: This strategy involves gradually altering a behavior, rewarding closer and closer approximations of the desired behavior. Applications of Behavior Analysis Behavior analysis has proven to be a particularly effective learning tool for helping children with autism?? or developmental delays acquire and maintain new skills. These treatments include the Lovaas Method and ABA (applied behavior analysis) and utilize techniques such as discrete trial training. The basic principles of behavior medication are often adapted for use in educational settings, the workplace, and childcare.

Narrative by Judith Ortiz Cofer Essay - 627 Words

The narrative written by Judith Ortiz Cofer discusses some of the many experiences she has encountered throughout her life dealing with stereotypes and common misconceptions of Latin American women. To further engage her audience in the story, she provides detailed past experiences that have stood out to her the most. In order for the readers to fully understand those past encounters, some of which are cultural and common among Latinos, Cofer explains them in careful detail. For example, Cofer explains the concept of piropos which are poems composed on the spot by men to women as a form of admiration. This helps her introduce the audience to her own experiences with piropos and how she has dealt with them throughout her life. One of the†¦show more content†¦She knew how to dress for specific occasions such as a Sunday mass or a party, but this was a challenge. This shows the audience that Latin girls dress the way they do because of their cultural background and something th at is considered acceptable in Latin America can differ from what is acceptable in North America. Cofer goes on to discuss how the way Latin women dress can be misinterpreted as a come-on to men when in fact, that usually isn’t the case because dressing that way is normal and even encouraged by Latin mothers. The point Cofer was trying to display in her narrative was that the outward appearance of Latin women should not be mistaken with who they are but rather be considered as part of their culture. This narrative describes a cultural clash between America’s mainstream views and opinions and Latin women who have to struggle with these stereotypes from a young age. Career Day is one of the examples in which Cofer experienced falling under one of those stereotypes and feeling like an outcast when the nuns at her school displayed the Latin girls as the negative models of Career Day. Cofer’s strong opinions against these stereotypes is made clear throughout the stor y as she explains random instances she remembers of how others view Latin girls and how the media often objectifies women comparing them to â€Å"Hot Tamales† and other offensiveShow MoreRelatedCultural Assimilation In Silent Dancing By Judith Ortiz Cofer1052 Words   |  5 PagesIn 1990, a Puerto Rican immigrant writer Judith Ortiz Cofer published Silent Dancing: A Partial Remembrance of Puerto Rican Childhood, a collection of poems and short stories that combined together construct a memoir.

Materials For Torque And Aluminium Engineering Essay Free Essays

Modern vehicles with constituents made of aluminum can be 24 % lighter than one with steel, which besides allows fuel ingestion to be reduced by 2 liters per 100 kilometers. Besides the above mentioned facts, aluminum is besides corrosion opposition ( Aluminium Leader 2011 ) . Engineering applications are germinating quickly, enabling new constituent designs, for burden bearing and fabrication systems. We will write a custom essay sample on Materials For Torque And Aluminium Engineering Essay or any similar topic only for you Order Now Modern stuffs include fibre complexs, proficient ceramics, technology polymers and high temperature metal metals ( Ashby et al. , 1985 ) . The vehicle interior decorator must be cognizant of these developments and be able to choose the right stuff for a given application, equilibrating belongingss with processing, utilizing a basic apprehension of the structural inter-relationships. Metallic elements and Alloies: Metallic elements are non copiously available, therefore, can merely be used for specializer applications such as catalytic convertors and powerful lasting magnets. However, metals such as Fe, Cu and aluminum, which are copiously available and can be easy extracted are widely used in both, pure every bit good as alloy signifier ( Cottrell, 1985 ) . At present, loosely used and cheapest stuffs are Iron-based or ferric metals. Mild or low C steel is adequately strong with output strengths changing between 220 and 300 MPa for low burden uses. Further, it is easy to cut, flex, machine and dyer’s rocket. High output strength is required for drive shafts and gear wheels due to higher tonss. Therefore, medium C, high C or metal steels, ( yield strengths of 400 MPa ) are used for these intents. Higher strength and wear opposition are needed for bearing surfaces. For such parts, medium and high C steels, hardened by heat intervention and extinction ( increases the output strengths to about 1000 MPa ) , are used. Unfortunately, these hardened steels become brickle following this heat intervention, so that a farther mild re-heating, called annealing, is required. This reduces the crispness whilst keeping most of the strength and hardness. Stainless steel steels are alloys with a assortment of signifiers, viz. , Austenitic, Ferritic, Martensitic and the newer Duplex steels. A common composing contains: Chromium – 18 % nickel – 8 % ( BS 970, 1991 ) Their corrosion opposition and creep opposition is superior to kick C steels, peculiarly at high temperatures, nevertheless, higher stuff and fabrication costs limit their usage in vehicle technology to specialist applications such as longer life exhaust systems. Cast chainss have 2 to 4 % C, in contrast to the 1 % or less for other ferric metals mentioned supra. This makes them brittle, with hapless impact belongingss, unless heat-treated to bring forth malleable Fe. Since the higher C content reduces the thaw point, it makes pouring into complex shaped molds much easier, hence, it is more readily project than steel. The C in the signifier of black lead makes an ideal boundary lubricator, so that cylinders and Pistons have good wear features, for usage in Diesel engines. However, it is now mostly replaced by the much lighter aluminum alloys for these applications in gasoline engines. Copper is besides used in vehicle technology. It is more expensive than steel, but is malleable and can be easy shaped. Due to its high electrical conduction, it is used in wiring and telegraphing systems. Brass is a Cu metal, normally with 35 % Zn, which makes it easier to machine yet stronger than pure Cu. This helps bring forthing complex forms for electrical adjustments. However, such metals suffer from a long term job, known as A ; acirc ; ˆ?dezincification A ; acirc ; ˆâ„ ¢ , in H2O. Corrosion can be minimized by utilizing the more expensive Cu metal, bronze, where Sn is the debasing component, although this stuff may be harder to machine. Copper-nickel metals have good weirdo opposition at high temperatures where they are besides corrosion resistant. The latter belongings is made usage of in brake fluid pipe-work. Aluminum and its metals have a major advantage over steels and Cu alloys, as vehicle technology stuffs. As mentioned above, their much lower densenesss lead to take down weight constituents and attendant fuel energy nest eggs. Whilst aluminum ores are abundant, the extraction of pure aluminum is really energy demanding, being electro-chemical in nature instead than the purely chemical procedure used for steels. Copper occupies an intermediate place on this point. Thus, pure aluminum is more expensive than Fe and Cu and has lower characteristic strength and stiffness. However, it does hold corrosion opposition with good thermal and electrical conduction. A broad scope of metals is now available with assorted heat interventions and fabricating chances. These stuffs have now replaced steels and Cu metals in many vehicle constituent applications, where their higher stuffs costs can be designed out, see Figure 4.1. However, stuffs developments are such that aluminum metals are themselves in competition with polymers and composite stuffs for such applications as vehicle body-work, see Figure 4.2. A composite stuff is a combination of two stuffs, with its ain typical belongingss. Its strength or other desirable quality is better or really different from either of its constituents working entirely. The chief attractive force of composite stuffs is that they are lighter, stiffer and stronger than most other structural stuffs. They were developed to run into the terrible demands of supersonic flight, infinite geographic expedition and deep H2O applications but are now used in general technology including automotive applications. Composite stuffs imitate nature. Wood is a complex of cellulose and lignin ; cellulose fibers are strong in tenseness but flexible and lignin Acts of the Apostless to cement the fibers together to make a stuff with stiffness. Man-made complexs achieve similar consequences by uniting strong fibers such as C or glass, in a softer matrix such as epoxy or polyester rosin. Considerable monetary value fluctuations in stuffs occur from clip to clip due to fuel monetary value fluctuations so that the cost values should be considered in comparative footings. The choice of a metal for a design application requires experimental informations. The first phase will find which group of metals should be used, steels, Cu or aluminum ( see Table 4.1 ) . Then a specific choice will necessitate more elaborate information. Testing of stuffs and constituents will hence be required. Some belongingss are mostly independent of composing, microstructure and processing. These include denseness, modulus, thermic enlargement and specific heat. However, many belongingss are really dependent on metal composing, microstructure, heat- intervention and mechanical history. These belongingss include output and tensile strength, ductileness, break stamina, weirdo and fatigue strength, so that specific information is required ( Smith, 1993 ) .

Things Fall Apart and Exile free essay sample

The exile Gilgamesh encounters teaches him a valuable lesson that a person cannot escape their own mortality and he can still keep the memory of his best friend. He has a new outlook on life and does not take pride in the worldly aspirations. It is a humbling experience and he returns to his kingdom with a new found appreciation for his people’s work. E. Gilgamesh’s experience of exile allows the reader to relate through the common feeling of grief. III. Second Protagonist’s Exile – Prospero A. In The Tempest, Prospero’s exile is one that is forced upon by the jealousy and treacherous act of his own brother, Antonio. . Sutton argues that Prospero’s story is very similar to that of Joseph from the book of Genesis. 2. â€Å"Joseph and Prospero parallel each other as victims of jealous siblings† (Sutton 225). B. Prospero’s exile leaves him stranded on an island for twelve years with only the company of his daughter and his two serv ants. We will write a custom essay sample on Things Fall Apart and Exile or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page 1. He uses his time in exile to once again become a powerful ruler of his new territory. 2. â€Å"They eventually become de facto rulers of their adopted land, using their natural abilities combined with supernatural forces to gain power† (Sutton 225). C. Despite Prospero’s betrayal by his own brother; he seeks to forgive him instead of choosing revenge. 1. When it is time to face his brother, Prospero tells Antonio â€Å"I do forgive Thy rankest fault, all of them† (Shakespeare V. i. 151-152). 2. Forgiveness is another similarity between Prospero and Joseph â€Å"†¦in both works the protagonists eventually forgive their brothers† (Sutton 227). D. The experience of exile restores Prospero’s dukedom, but only after seeking forgiveness. He is able to set himself free from the vengeful acts that were cast upon him and restore goodness within his self and others. E. In the beginning of the play, Prospero’s exile leads the reader to think he is seeking revenge, but in the end his exile is a part of a larger theme which is forgiveness. IV. Third Protagonist – Okonkwo A. Okonkwo’s exile in Things Fall Apart is much different than that of Gilgamesh and Prospero’s in that it is a result of his own actions. 1. He is exiled by his clansmen when he commits a female crime, killing another clansman by accident (Achebe 124). 2. The only course of action Okonkwo can take is to abide by the laws of Umuofia and leave his native land for seven years B. The exile Okonkwo faces only adds more to his anger and bitterness. Okonkwo’s alienation causes him to have a pessimistic outlook, focusing more on what has been taken from him. 1. Although he is thankful for the welcoming of his mother’s kinsmen, Okonkwo regrets every day of his exile (Achebe 162). C. Okonkwo does not learn anything from his exile, but reverts back to his survival skills and hard work to â€Å"prosper in his motherland† (Achebe 162). D. Okonkwo is the only protagonist that did not change from his experience. His experience of exile reveals no change of his pessimistic outlook and only hardens his heart more. When he returns home, his actions show that he is meaner, angrier, and more rebellious. E. Okonkwo’s experience of exile leaves a shocking ending with Okonkwo taking his own life. V. Conclusion A. The experience of exile can lead a person through a dark tunnel, but it does not mean that there cannot be light at the end. B. Gilgamesh, Prospero, and Okonkwo each portray how when taken from their homeland, exile is a hurtful experience, but it can also enrich their lives and reveal their true character. C. The experience of exile, in the stories of The Epic of Gilgamesh, The Tempest, and Things Fall Apart, helps reveal the main plot of the texts and the characters. Works Cited Achebe, Chinua.

Amoeba Anatomy, Digestion, and Reproduction

Amoeba Anatomy, Digestion, and Reproduction Amoebas are unicellular eukaryotic organisms classified in the Kingdom Protista. Amoebas are amorphous and appear as jelly-like blobs as they move about. These microscopic protozoa move by changing their shape, exhibiting a unique type of crawling motion that has come to be known as amoeboid movement. Amoebas make their homes in salt water and freshwater aquatic environments, wet soils, and some parasitic amoebas inhabit animals and humans. Key Takeaways: Amoebas An amoeba is an aquatic, single-celled protist characterized by a gelatinous body, amorphous shape, and amoeboid movement.Amoebas can form temporary extensions of their cytoplasm known as pseudopodia or false feet which can be used for locomotion or capturing food.Food acquisition is amoebas occurs by a type of endocytosis called phagocytosis. The food source (bacterium, algae, etc.) is engulfed whole, digested, and the waste expelled.Amoebas commonly reproduce by binary fission, a process in which the cell divides into two identical cells.Some species can cause disease in humans such as amebiasis, amoebic meningoencephalitis, and cornea infections of the eye. Classification Amoebas belong to the Domain Eukarya, Kingdom Protista, Phyllum Protozoa, Class Rhizopoda, Order Amoebida, and the Family Amoebidae. Amoeba Anatomy Amoebas are simple in form consisting of cytoplasm surrounded by a cell membrane. The outer portion of the cytoplasm (ectoplasm) is clear and gel-like, while the inner portion of the cytoplasm (endoplasm) is granular and contains organelles, such as a nuclei, mitochondria, and vacuoles. Some vacuoles digest food, while others expel excess water and waste from the cell through the plasma membrane. The most unique aspect of amoeba anatomy is the formation of temporary extensions of the cytoplasm known as pseudopodia. These false feet are used for locomotion, as well as to capture food (bacteria, algae, and other microscopic organisms). Pseudopodia may be broad or thread-like in appearance with many forming at one time or one large extension may form when needed. Amoebas dont have lungs or any other type of respiratory organ. Respiration occurs as dissolved oxygen in the water diffuses across the cell membrane. In turn, carbon dioxide is eliminated from the amoeba by diffusion across the membrane into the surrounding water. Water is also able to cross the amoeba plasma membrane by osmosis. Any excess accumulation of water is expelled by contractile vacuoles within the amoeba. Nutrient Acquisition and Digestion Amoebas obtain food by capturing their prey with their pseudopodia. The food is internalized through a type of endocytosis known as phagocytosis. In this process, the pseudopodia surround and engulf a bacterium or other food source. A food vacuole forms around the food particle as it is internalized by the amoeba. Organelles known as lysosomes fuse with the vacuole releasing digestive enzymes inside the vacuole. Nutrients are obtained as the enzymes digest the food inside the vacuole. Once the meal is complete, the food vacuole dissolves. Reproduction Amoebas reproduce by the asexual process of binary fission. In binary fission, a single cell divides forming two identical cells. This type of reproduction happens as a result of mitosis. In mitosis, replicated DNA and organelles are divided between two daughter cells. These cells are genetically identical. Some amoeba also reproduce by multiple fission. In multiple fission, the amoeba secretes a three-layered wall of cells that harden around its body. This layer, known as a cyst, protects the amoeba when conditions become harsh. Protected in the cyst, the nucleus divides several times. This nuclear division is followed by the division of the cytoplasm for the same number of times. The result of multiple fission is the production of several daughter cells that are released once conditions become favorable again and the cyst ruptures. In some cases, amoebas also reproduce by producing spores. Parasitic Amoebas Some amoeba are parasitic and cause serious illness and even death in humans. Entamoeba histolytica cause amebiasis, a condition resulting in diarrhea and stomach pain. These microbes also cause amebic dysentery, a severe form of amebiasis. Entamoeba histolytica travel through the digestive system and inhabit the large intestines. In rare cases, they can enter the bloodstream and infect the liver or brain. Another type of amoeba, Naegleria fowleri, causes the brain disease amoebic meningoencephalitis. Also known as brain-eating amoeba, these organisms typically inhabit warm lakes, ponds, soil, and untreated pools. If N. fowleri enter the body though the nose, they can travel to the frontal lobe of the brain and cause a serious infection. The microbes feed on brain matter by releasing enzymes that dissolve brain tissue. N. fowleri infection in humans is rare but most often fatal. Acanthamoeba cause the disease Acanthamoeba keratitis. This disease results from an infection of the cornea of the eye. Acanthamoeba keratitis can cause eye pain, vision problems, and may result in blindness if left untreated. Individuals who wear contact lenses most often experience this type of infection. Contact lenses can become contaminated with Acanthamoeba if they are not properly disinfected and stored, or if worn while showering or swimming. To reduce the risk of developing Acanthamoeba keratitis, the CDC recommends that you properly wash and dry your hands before handling contact lenses, clean or replace lenses when needed, and store lenses in a sterile solution.
