Evaluation Of A Convenience Sample Of 40 Participants ( 20 Men )

Gender differences have been recorded by researches from single neurons in the cell to system level processes (Cahill 2006), and certain scientists proposed that sex hormones influence the development of prefrontal cortex, and this is supposed to be the cause of the differences in working memory performance (Duff & Hampson, 2001). This study further investigated the existence and nature of this gender difference. A sample of 497 Monash University psychology undergraduates (385 females and 112 males; ages 18 – 64) were recruited for this study. Working memory performance was tested with online 'spatial working memory ' test, and 2D:4D finger length ratio was used as an indirect measure of sex hormone levels. The results revealed no sex differences in the working memory performance, but variance in 2D:4D ratio – females had a larger ratio than males. Memory reaction time was negatively correlated with 2D:4D ratio, thus, females had a quicker reaction time.

However in regards to general results between both genders it was shown that no definite statistical mean yielded notable results (Alansari & Baroun, 2004). Stroop (1935) also showed that women college students also showed a difference when compared to the men and tended to have higher word reading results, but in regards to the genders showed no significant differentiation between both at the cognitive level.

In the study, the between-groups design and the cross-sectional design were used for research. There were 243 participants between the ages of 18 and 39, and the majority were females and Caucasians. The average age was about 21 years old.

Within the study, the demographics of the participants were made available, including gender, age, race and ethnicity, marital status, and educational and employment status. Special consideration and statistical analysis was conducted for those in the High

Results: The study evaluated 22,599 samples representing 503,374,648 weighted individuals nationally from 2005-2008. Average age was 49 years, female 57%, Caucasian 83%, and the greatest percentage were from the South region of United States of America (36.8%).

Short term memory refers to a memory system that stores a limited amount of information in conscious awareness for a brief period of time, (McLeod, 2007). Short term memory is integral to cognitive activities such as reading, comprehension & problem solving & language as without it we would be unable to recall the beginning of a sentence by the time we reach the end of it, nor e.g. perform simple mental mathematical calculations (Hedden,et al, 2004). Interestingly because language , reading and problem solving occur sequentially (Hedden,et al, 2004) , information stored in short term memory is stored and retrieved sequentially.( McLeod, 2007) for example, when asked to recall the 3rd digit in a numeric sequence, one would go through the sequence in the order that it was heard in order to retrieve the 3rd digit in a numerical sequence, one would go through the sequence in the order that it was heard to retrieve the 3rd digit.

The results indicated Mayra’s ability to process information that was being held within short-term memory was within the Above Average range (Working Memory standard score = 113). Mayra’s performance of the subtest Recall of Digits backward (T-Score = 60) was better than her performance on the Recall of Sequential Order subtest (T-Score = 55). Both tasks required Mayra to listen to a list of verbally presented words and/or numbers. She was required to hold the list in short-term memory while working on the list and re-ordering the words/numbers. Recall of Digits Backward was presented verbally. On Recall of Digits Backward, Mayra used an interesting strategy to successfully recall the numbers. When she struggled to remember the order of the numbers, she would verbally recall the list in the initial order and go back and say them in the required, backward form. On the Recall of Sequential Order subtest, the examiner presented the lists of body parts verbally. Mayra was required to encode the presented information and store it in her short-term memory. Then, she needed to mentally manipulate the encoded information to produce the body parts in a specific order. The ordering of the information required Mayra to visualize the body parts in sequential order from head to toe (e.g., elbow, foot, shoulder → shoulder, elbow, foot). Most

The data collected from this experiment will not contain personal identifiable information. Only the researchers involved with this experiment will have access to the data collected. The paperwork will be stored in a locked file cabinet and the data stored on hard drive on a password protected computer. All information obtained from participants will be kept confidential and protected from unauthorized access. All data sheets will be coded with group labels and numbers. No personal identifying marks of any kind will be present on any of the data forms. The data sheets will be stored separately from the signed consent forms. All data from this study will be reported as group averages. No single identifiable cases will ever be reported.

Data used in this study is from a previously prepared collection for a different study and hence does not require any instruments. Use of Microsoft Excel and graphpad, an online software, helped in calculating the results and analyzing the data.

For the purpose of this paper, I will only focus on three hypotheses and three specific elements of the research. First, given that boys are more likely to play video games more often and engage in more psychical activity they should be more adapt to remembering pictures presented dynamically then statically; opposed to girls who were expected to remember pictures that were presented statically. Next, congruent with the gender schema theory, the researcher hypothesized that both males and females are more likely to remember and be able to recall stimuli that is related to one’s sex and have a hard time processing and recalling stimuli counter stereotypical to one’s sex. Lastly, gender-stereotypical stimuli are predicted to be recalled better under intentional conditions rather than incidental. For this research, nearly 160 children and adolescents were presented with 36 gender stereotypical toy photographs that is, they were highly classified as being masculine, feminine, or neutral. In addition, each was categorized based on its function. The participants were randomly assigned to two groups; the incidental memory condition and the intentional memory condition. Half of the participants were first presented with 36 static pictures (SOM) and the other half presented with 36 dynamic pictures (DOM). The participants in the SOM were presented with photographs appearing in the center of the screen for nearly 5 seconds and were

The primary outcome in the current study was measuring the ability to correctly recall different character sets that included similar or dissimilar distractor tasks. To test this hypothesis, the number of correctly recalled character sets were analyzed by a 2 (character set: consonants vs. digits) X 2 (distractor task: word-based vs. number-based) between-subjects ANOVA. The main effect for character sets was not statistically significant, F(1, 106) = 1.16, p = .284, ηp² = .01. The main effect for distractor tasks also produced non-statistically significant results, F(1, 106) = 1.0, p = .758, ηp² = .001 . Lastly the interaction effect showed a non-statistically significant result F(1, 106) = 1.22, p = .271, ηp² = .011. Descriptive statistics for these data can be found in Table 1.

The questions of if and how gender plays a role in a person's STM capabilities and working memory is one that has been visited and revisited over time, but has generally yielded fairly consistent results: one sex does not dominate the other in terms of which has a more functional STM, rather, men and women maintain their own respective skills regarding different areas of STM ("Sex Differences in Memory"; Loftus et al. 82).
