    Most likely, her only correct perceptions are those perceptions about herself such as: "I am moving my arm," or "I am swinging my legs." The external stimuli are ineffective in this person, whereas a person with bradykinesia can only react completely and at a normal speed to external stimuli. Because of damage to signal pathways, the internal stimuli are ineffectively activated. (1) Bradykinesia is a Greek term that means "slow movement", and it is one of the constituents of Parkinson's disease

  • How To Listen In Sonny's Blues By James Baldwin

    682 Words  | 2 Pages

    Listen in James Baldwin's Sonny's Blues In James Baldwin's "Sonny's Blues", the verb, to listen, is employed many times in varying contexts. This theme is developed throughout the story as the narrator learns to listen more closely to the aural stimuli (or sounds) which enter his ears. In order to understand the narrator's heightened degree of perception as it unfolds in "Sonny's Blues", it is necessary to begin with a thorough discussion of hearing and listening in general, and then as they relate

  • Investigating the Effect of Selective Attention on the Performance of a Motor Skill

    1250 Words  | 3 Pages

    motor skills such as catching, visual selective attention is critical for a successful performance; our ability to attend to only a specific portion of information and not be distracted from the irrelevant information. Certain characteristics of stimuli, for instance the orange ball attracts attention because they receive our involuntary attention. This is because the ball is visual and meaningful, however because the catcher is expecting the orange ball it results in an increased probability

  • The Simon Effect: A Case Study

    835 Words  | 2 Pages

    responding to stimuli that occur in the same relative location as the response, even though the location information is irrelevant to the actual task (Simon, 1969). In studying the Simon effect it is possible to understand response selection. There are three stages which must be taken into consideration: Stimulus identification, response selection and response execution. Thus, the focus of this experiment is to determine whether or not people are faster and perhaps more accurate responding to stimuli in the

  • Classical vs. Operant Conditioning

    717 Words  | 2 Pages

    Classical conditioning and operant conditioning are different learning methods. The two methods have the word conditioning in common. What is conditioning? Conditioning is the acquisition of specific patterns of behavior in the presence of well-defined stimuli. Both classical and operant conditioning are basic forms of learning. Classical conditioning is a type of learning in which an organism learns to transfer a natural response from one stimulus to another, previously neutral stimulus. Manipulating reflexes

  • Theoretical Perspectives of Certain Disorders

    1013 Words  | 3 Pages

    The theory of classical conditioning says that phobias are the result of learned associations of neutral stimuli and frightening events. This also demonstrates why an individual might have a phobia of guns after being shot by one. Biological theorists believe that people with anxiety disorders have unusually responsive autonomic systems that are more easily aroused by environmental stimuli. This condition is known as autonomic lability that contributes to a tendency to be jumpy or anxious. They

  • Brain Plasticity

    1130 Words  | 3 Pages

    I found a partial answer in the concept of plasticity. According to source (1), "Plasticity refers to how circuits in the brain change--organize and reorganize--in response to experience, or sensory stimulation." There appear be four types of stimuli to which a brain responds with change: developmental, such as in the newly formed and ever evolving brain of a child; activity dependent, such as in cases of lost senses; learning and memory, in which the brain changes in response to a particular

    thought and action. Evidence concerning the true relationship of mind, body, and behavior has been elucidated through discoveries of the neural pathways enabling active translation of input to output. We have suggested the origins of action, discussed stimuli both internal and external, as well as concepts of self, agency, and personality interwoven with a more accessible comprehension of physical functionality. However, I remain unable to superimpose upon the current construct of brain and behavior a

  • The Effect of Homophone Training on Pseudohomophone Reaction Time

    2814 Words  | 6 Pages

    were shown two word strings simultaneously and asked to respond as to which was a correct word. Participants were students from the University of Nottingham split into two different groups that were subject too different training conditions. Stimuli were four letter single syllabale word strings including homophones, regular words, non word strings, and pseudohomophones as used in previous research by Underwood (1988). The results obtained did not show a significant difference in reaction

    elements that close together.  Closure is the tendency to fill in the gaps in incomplete stimuli. A perception of people that apply to closure would be the Halo Effect. The halo effect allows one salient characteristic to overshadow ones evaluation of another in multiple arenas. In other words a person will “fill in the gaps” of another person.  Continuation is the tendency to organize stimuli into continuous lines or patterns. Selective Perception is much like continuation. Selective

    classical conditioning. “Classical conditioning is when a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response (Santrock, p.147).” Pavlov’s dog salivates in response to a number of stimuli related with food, such as the sight of the food dish, the sight of the individual who brought the food into the room, and the sound of the door closing when the food arrives. Pavlov recognized that the dog’s association of these sights and sounds

    time + movement time In order to be a skilled performer the ability to combine quick reactions with quick movements is vital in order to be able to respond to stimuli effectively. For example in 100m sprinting the most successful sprinter is going to be the one who exerts pressure onto the blocks by his feet after hearing the stimuli (starting gun) first and then moving his feet off the blocks first. this is because his quick combination of reaction and movement time has given him the quickest

  • The Coorelation between Drug Tolerance and the Environment

    1259 Words  | 3 Pages

    The Coorelation between Drug Tolerance and the Environment When considering the dynamics of brain and behavior, another component that enters the equation is environment. If brain equals behavior then changes to either should result in an altercation to the other component. The question that arises is whether a change in the environment produces change in brain chemistry and therefore, behavior. A connection between brain, behavior and environment may be observed in the context of drug tolerance

  • Animal behavior

    An experiment was performed by placing a large red sheet of paper in the tank. This made the male fish aggressive. This aggressiveness is what will make the male more “fit” in order provide more sperm to the females. The red was the releaser/sign stimuli in this case. If you take a chick for example, its mother will respond to sound instead of sight. When a chick is distressed and is placed in a sound proof container, the mother will not respond. However, when there is a physical barrier but not sound

  • The Reasons Sex Offenders Offend

    aggressor has a sadistic aim where he feels that some violence must occur for there to be sexual pleasure. (Hollin, p. 41) The second theory is the behavioral theory, which states that "rapists in general are less aroused by stimuli depicting forceful sex that by stimuli depicting mutually enjoyable sex."(Hollin, p. 42) There is an exception to this with extremely violent rapists whereas they are just as aroused by forceful depictions as they are by mutual enjoyment depictions The third theory

  • The Portrayal of Women in the Media

    3423 Words  | 7 Pages

    These differences include gender, sexual orientation, economic status, location, race, ethnicity, and more. Advertisers have substantial knowledge of what appeals to each of these demographics and how these demographics will respond to different stimuli (i.e. visual audio, ect.) as well as where the advertising will be most effective. In other words, advertisers find it more beneficial to target specific audiences (Furnham; Mak, 1999). One of the central audiences that advertisers focus their attention

  • The History of the Roy Adaptation Model

    1843 Words  | 4 Pages

    Vertalanffy’s use of systems theory was a key component in the early concept of the model, as was the work of Helson. Helson defined adaptation as the process of responding positively to environmental changes, and then went on to describe three types of stimuli, those being focal, contextual, and residual. Roy made derivations of these concepts for use in describing situations of people in both health and illness. Roy’s view of the person as an adaptive system took shape from this early work, with the congnator

  • Punishment as a form of behaviour modification

    2351 Words  | 5 Pages

    Introduction Punishment is a process through which “the consequence of a response decreases the likelihood that the response will recur” (Gray, 2002, pp.115). Further, punishment can be seen as an effort to decrease the response rate to stimuli by either removing a desired stimulus or presenting one which is undesired (Gray, 2002). Recent studies suggest that punishment can be an effective method of behaviour modification. However, as reported in Lerman and Vorndran (2002), there are a number of

  • Vision and Blindsight

    1629 Words  | 4 Pages

    somehow, visual cues are processed. Visual inputs presented to the blind field affect the patient's response to stimulus in the normal visual field. Reaction times to stimuli are affected as well as the interpretation of the stimuli. A visual cues presented in the blind field may suggest a certain interpretation of an ambiguous stimuli. For example, the interpretation of the word "bank", presented as an auditory cue, differs depending on whether the word "river" or "money" is presented to the blind

  • Autism: A Disorder of Conflicting Causes and Treatments

    disability include the stereotypical physical contortions and hand-flapping motions commonly associated with autism, as well as inability to relate to the outside world, limited social skills, lack of concentration, and hypersensitivity to certain stimuli-particularly noise (1). Perceived causes include poor fetal development, genetics, allergies, and a lack of crucial enzymes. Because for many years the disorder was thought to be a result of poor parenting, only recent studies have begun any attempts
