Evaluate/Compare and Contrast/Discuss/Examine models or theories of one cognitive process with reference to research studies (22)

Human beings actively process information and it is cognitive processes that guide behavior. These cognitive processes are influenced by social and cultural factors. One of the cognitive processes is memory. Many researchers and psychologies have proved that the mind can be studies scientifically by developing theories and using a number of scientific research methods. This is demonstrated in theories and models of cognition which are discussed and continuously tested. The key characteristics of a good memory models are first, testability; second, simplicity; lastly, applicability. This essay looks at strength and limitation/similarities and differences/examine/discuss of models of one cognitive process, which is memory, with reference to research studies.

Not all of developing models have such characteristics above.

MSM by Atkinson and Shiffrin (1968)
* Sensory memory, STM and LTM as permanent structural components of the memory system. * Rehearsal is a control process, which acts as permanent structural components of the memory system. * Rehearsal is a control process, which acts as a buffer between sensory memory and LTM, and helps the transfer of information to LTM.

-Evidence
* H.M. Case studies by Milner (1966)
-Studies of brain-damaged, amnesic patients appear to support the STM-LTM distinction. While STM continues to function fairly normally, LTM functioning is impaired.

* Peterson and Peterson (1959)
-When rehearsal is prevented, information is very rapidly lost from STS.

* Murdock (1962)
-Primacy effect reflects recall from LTM, while the recency effect reflects recall from STM. Together they comprise the serial position effect.

* Glazer and Cunitz (1966)

-Strength
* The model pioneered the new approach to memeory where humans are seen as information processors...

Introduction
The objective of this task is to explore the relationship between the positions of points within circles that intersect.
The first figure illustrates circle C1 with radius r, centre O, and any point P. r is the distance between the centre O and any point (such as A) of circle C1....

Internal Assessment – LASCAP’S Fraction
The goal of this task is to consider a set of fractions which are presented in a symmetrical, recurring sequence, and to find a general statement for the pattern.
The presented pattern is:
Row 1

Notation and Terminology
Check for the following:
• I did not use calculator notation. (I didn’t include things like ‘x^2’ for or Sn for Sn)
• I used appropriate mathematical vocabulary.
Communication
Check for the following:
• The reader will not need to refer to the list of questions in order to understand my work.
• My responses are not numbered.
• I have an introduction, conclusion,...

...In Lacsap’s Fractions, En(r) refers to the (r+1)th term in the nth row. The numerator and denominator are found separately, therefore to find the general statement, two different equations, one for the numerator and one for the denominator, must be found. Let M=numerator and let D=denominator so that En(r) = M/D.
To find the numerator for any number of Lacsap’s Fractions, an equation must be made that uses the row number to find the numerator. Because the numerator changes depending on the...

...OPA Circle Style
The three circles; O, P and A intersect to create an interesting investigation regarding circles. Since this is a Calculus course, the investigation does have to deal with Derivatives. The most important and the focus of this portfolio is the line segment, OP’. Using the given diagram above, this investigation consists of finding the general equation for discovering OP’.
The values that are given are that r, is the radius of C1...

* INTRODUCTION
This investigation is going to do research patterns relates to the Lacsap’s Fractions. For its external structure, Lacsap’s Fraction is analogous to Pascal’s Triangle. Lacsap’s Fraction presents the way of generating and organizing the binomial coefficients. Within this investigation, the work is planning to be divided into two parts. In the first part, the content will relate to the pattern of numerators. In the second part, I...

Lacsap’s Fractions
Lacsap is Pascal spelled backward. Therefore, Pascal’s Triangle can be used practically especially with this diagram.
(Diagram 1)
This diagram is of Pascal’s Triangle and shows the relationship of the row number, n, and the diagonal columns, r. This is evident in Lacsap’s Fractions as well, and can be used to help understand some of the following...

The effect of various fruit and vegetable cell membranes on their water potential
Independent variable: Type of fruit or vegetable. (Produce used: Russet potatoes, Pascal celery, Gala apple, Navel orange, and Imperator carrot). The fruit or vegetable will be placed in six 56.7 gram cups, ranging with sucrose molarities of 0 (distilled water), 0.2, 0.4, 0.6, 0.8, 1.0, with 5 trials, leading to 30 cups for each produce variable.
