The human brain struggles to effectively perform two competing tasks at the same time (Dzubak, 2007, p. 7). For the STM it has a limited capacity, it struggles when there is just too many sensory stimuli’s present. Identify and articulate what you see as the sensory perception problem involved. It would involve the use of the Working memory. By referring to the temporary storage and processing to information which can be used with problem solving.
Kahneman (as cited in Edgar, 2007) explains it in the limited capacity theory of attention. According to it, “the brain contains limited-capacity central processor responsible for analyzing incoming information and integrating it to information already held in memory” (Edgar, 2007, pp.11). Thus, when a person tries to do many things at once interference can occur if those things compete for the same pool of resources. However, Macleod (as cited in Edgar, 2007) showed that it is possible to do two things at once without interference. In his study, participants had to carry out a visual and an auditory task and respond to them by saying ‘bip’.
The strength of those pathways determines how quickly you recall the memory. To reinforce that initial memory, it must move multiple times across the nerve cells, retracing its steps. Memory formation largely occurs in the brain's limbic system, which regulates learning, memory and emotions. The cortex is the temporary storage place of short-term memories and the area where the brain puts the new
Abstract Fonts can attract different kinds of attention, and also different levels of processing and memory. In this experiment we were particularly interested to see if font styles have any influence on people’s abilities to recall information with the three specific font styles we chose: normal (Times New Roman), all-capitalized and cursive. Our hypothesis was that it was much easier to remember something if the information appeared in the normal font. The participants were college students in a Cognitive Psychology course (N = 27). Each participant received a one-page fictional story and was then tested on recall of the important points covered in the story.
The Effects of Retention Delay and Rotation on Spatial Memory. Abstract: The purpose of the experiment was to attain empirical evidence on how egocentric and allocentric representations are encoded in the short-term spatial memory, and how the manipulation of certain factors can affect this process. The aim was to discover whether rotating stimuli and increasing the time delay between observations and testing phases would have an effect on participants’ accuracy when remembering the position of a target. The study used a within subjects design, with all participants taking part in all conditions. A significant effect was found for rotation and also for the increased time delay, meaning that short-term spatial memory performance is greater when the orientation of the stimuli is not altered and when the retention delay is only a few seconds.
[these require focused attention?] This led to the development of two-process theories; which suggest that automatic and controlled processes operate simultaneously, so that tasks are “automatically” carried [could be considered more of a continuum?] Kahneman (1973, as cited in Edgar, 2007) suggested that there is a central processor within the brain which is of limited capacity and that some information cannot be processed. [there is too much input from our senses to be able to cope with] Kahneman explained how the brain acts as a physical filter and defined attention as mental effort; limited resources being allocated
Evaluate the extent to which a cognitive process is reliable This essay will explore the extent a cognitive process is reliable in terms of memory. By focusing at different types of memory it will be possible to deduce whether or not memory is reliable. The essay will focus on ‘Schemas and eyewitness testimony’ (Loftus and Palmer, 1974), ‘Weapons effect’ Loftus et al. (1987), ‘Serial position curves with immediate and delayed free recall’ (Glanzer and Cunitz, 1966), and ‘A study of flashbulb memory’ (Brown and Kulik, 1977), meaning they will all focus on different aspects of memory; eyewitness testimony, recalling information (an experiment focusing on the MSM model), and flashbulb memory. Each of the studies will also be supported by minor studies focusing on the same hypothesis.
Can intelligence change? To what extent is intelligence malleable? Extended Essay: Psychology Name: Candidate number: School: Nörre Gymnasium Word count: 37811 Abstract This essay investigated the research question: To what extent is intelligence malleable? It was necessary to start by presenting the debate on defining intelligence since there is not a complete consensus among psychologists, however, this paper accepted a definition which is generally accepted by respected psychologists; that ‘intelligence is the ability to deal with cognitive complexity’ (Gottfredson, 1998). In presenting and analysing empirical evidence such as Howe (1997) supporting the thesis that intelligence can, in fact, change under the right conditions and given enough time, a strong indication of malleability is provided.
Outline and evaluate the model of working memory In this essay I am going outline what is working memory in terms of psychology and evaluate it in terms of both advantages and limitation of the working memory model. The fact that short-term memory contains both new information and information retrieved from long-term memory has led some psychologists to prefer the term ‘working memory’ (Baddeley and Hitch, 1974; Baddeley, 1986,1992) Working memory model is an alternative to the multi-store model; it is a far more complex explanation of short-term memory. Baddeley and Hitch argued that the short-term memory was made up of several subsystems, each of them have a specialized function, rather than the short-term memory model being a single inflexible store. According to Martin, G. N, Carlson, N.R & Buskist, W. (2006) “According to Baddeley, working memory is a short-term memory system that allows us to retain material for current use and not just for transport into long-term memory.” Baddeley suggested this short-term memory as having three independent components that allow us to store temporarily visuo-spatial material and verbal material. These components were so-called the Visuo-Spatial Sketchpad and the Phonological Loop.
Emotional Intelligence history When psychologists began to write and think about intelligence, they initially focused on cognitive aspects, such as memory and problem-solving. However, some researchers recognized the importance of non-cognitive aspects early on: • Robert Thorndike was writing about social intelligence in 1937, • David Wechsler defined intelligence as the aggregate or global capacity of the individual to act purposefully, to think rationally, and to deal effectively with his environment (Wechsler, 1958, p. 7). Already in 1940 Wechsler referred to non-intellective as well as intellective elements (Wechsler, 1940), by which he meant affective, personal, and social factors. Furthermore, already in 1943 Wechsler was proposing that the non-intellective abilities are essential for predicting ones ability to succeed in life. • Howard Gardner began to write about multiple intelligence in 1983.
