This study examines the difference that categorization makes in memory recall exercises. It uses students from Queens College in an experiment in which categorized words are read aloud to one group and random words read aloud to a second group. The groups are then scored according to how many words they can recall correctly. The findings indicate that categorization makes a difference as the first group recalled more words correctly than the second group after two trials were conducted. Limitations are discussed and suggestions for future research are provided.
Memory Recall
What is memory? Memory consists of long-term and short-term recollections; it is a temporary store that has limited capacity. Today, scientists are still testing memory in efforts to better understand how it works and what it is capable of doing.
This study examines the outcome of an experiment based on memory recall. The phenomenon of memory recall is typically measured by providing cues and then recording the extent to which participants are able to recall data. As Lewis (1971) notes, "presentation affects item organization in memory storage, and a cue is effective along a certain dimension only if information is stored in that dimension" (p. 131). This means that memory recall is facilitated by a relationship between information and cues that are entwined together within a specific dimension relevant to the act of recall. Or, in other words, categorization matters in recall. Other variables that could potentially impact the outcome of recall are stimuli, such as sensory material (auditory, smell, taste, touch, etc.), surroundings (environment), and personal ability (habit) (Miller, 1956).
Miller's (1956) study identified the number seven as having a "Pythagorean" significance with regard to recalling items -- as evidenced...
Ameen Masoudi Combination Therapeutic Exercises with Manipulation for Reliving Pain and Increasing Range of Motion for Non-Specific Chronic Low Back Pain The lumbar spine is composed of the vertebrae as well as the ligaments beside the discs, nerves and muscles. This area is a common source of pain. This is one of reasons why people visit their physicians. Around seventy percent of people who live in advanced countries will have lower back pain
Carroll, J.S., Williams, M. & Gallivan, T.M. (2012). The ins and outs of change of shift handoffs between nurses: A communication challenge. BMJ Qual Saf (2012). doi:10.1136/bmjqs-2011-000614 Shift handoffs can be used as benchmarks to assess quality of communications among healthcare staff. Because communication overall is critical to quality of care, it is important to understand the factors that can improve shift handoff efficiency. Shift handoffs involve both technical communication and
Nonparametric Analysis of Data Set The datasets consist of the following variables: • Sub_num • Gender • Major • Coffee, and • Num_cups. The datasets are used for the nonparametric analysis to investigate whether the choices of college majors are different between males and female's individuals. The analysis is carried out with the chi-square test and the document presents the output as follows: Gender * Major Cross-tabulation Count Major Total Gender Total Chi-Square Tests Value Df Asymp. Sig. (2-sided) Pearson Chi-Square Likelihood Ratio Linear-by-Linear Association N of Valid Cases The minimum
Internal Validity Is maturation a possible threat to the internal validity of the study? Why or why not? For measures of academic achievement, six months (which is the intended length of the study) is not a long enough period of time to be very concerned about maturation as a threat to internal validity. Most academic achievement tests have longer durations. Maturation is something to be considered because of the varying ages of
If the numbers or the data will not be constant, the results will not be paralleled and will surely have discrepancy on its accuracy. Meanwhile, experimenter bias is a big threat to the accuracy and/or precision of the report's result. An example of the threat is not being able to identify all the factors that might affect the result. An experiment can be said biased if he/she has already an
To investigate these, each explanatory variable can be used in isolation to determine their specific impact upon the crime rate. The research can be conducted by first conducting an investigation of existing literature and statistics to determine the likelihood of each variable. Values can then be assigned to each variable to indicate the greatest to least likelihood. Qualitative research can then be conducted regarding the greatest likelihood of each explanatory variable.
