#### SPSS Data Analysis and Report

The researcher predicted that people will have a shorter digit span when asked to perform an articulatory task than when not asked to perform such a task. The research involved 20 participants who were divided onto two groups. Half the participants were assigned to the articulatory suppression and the other half to the control group.

##### Hypotheses

H0: Articulatory suppression will affect the phonological loop of the working memory where people will have a shorter digit span when asked to perform an articulatory task.

H1: Articulatory suppression will not affect the phonological loop of the working memory where people will have a shorter digit span when asked to perform an articulatory task.

According to Verma (2013), t-test is used to compare the values of the means from two samples and test whether it is likely that the samples are from populations having different mean values.

 Table 1 Report of mean and standard deviation of the two groups ARTICULATORY SUPPRESSION CONTROL GROUP Mean 5.50 7.20 N 10 10 Std. Deviation 1.080 1.317

The meanfor the articulatory suppression group is (M= 5.50) and the standard deviation is (SD= 1.08) whereas the mean for the control group is (M=7.20) and its standard deviation is (SD=1.317). This shows that the articulatory suppression affected the phonological loop of the working memory since the mean is below average for the two groups 5.5< 6.35.

A paired sample statistics test is a statistical procedure used to determine whether the mean difference between two sets of observations is zero (Korean, 2015). A paired sample t test was conducted to determine whether the mean difference between articulatory suppression group and the control group observations is zero. The paired samples statistics box shows that there was a significant difference in the articulatory suppression (M=5.50, SD=1.08) and no significant difference in the control group (M=7.2, SD=1.317).These results suggest that articulatory suppression has an effect on phonological loop of the working memory. When the individuals are asked to perform an articulatory task, they are unable to recite “la la la” while remembering the number sequence.

One sample t test is a procedure used to determine whether a sample comes from a population with a specific mean (Bozidar,2015). A one sample test was conducted to compare the articulatory suppression group and the control group.Since the p-value of the test is .000, which is less than the level of significance 0.05, we accept the null hypothesis that articulatory suppression will affect the phonological loop of the working memoryand conclude that there is a significant difference in the articulatory suppressiongroup to the control group.The positive t score implies that the sample proportion is greater than 62.7% but the evidence (based on the pvalue) is insufficient to conclude that the percentage of articulatory suppression group in the population is significantly different from 62.7%. These results suggest that articulatory suppression really has an effect on the phonological loop of the working memory. Specifically, the results suggest that when people are under articulatory suppression, they have a shorter digit span when asked to perform an articulatory task than when not asked to perform such a task. The average mean of the sample is 0.85 more than the articulatory suppression mean showing thatthat people had a shorter digit span when asked to perform an articulatory task than when not asked to perform such a task.

A one way ANOVA is a test used to determine whether there are statistically significant differences between the means of two or more independent groups (Natalie & Jaclyn,2010). A One-way between groups ANOVA was conducted to compare the effect of articulatory suppressionon reciting a sequence while remembering the number sequence.There was a significant effect of articulatory suppression on reciting a sequence while remembering a number sequence at the p<.05 level for the two conditions [F(4,5) = 0.41, P=0.996].

##### Conclusion and Recommendation

From the results above, it is clearly evident that articulatory suppression has an effect on the phonological loop of the working memory. From the mean of the articulatory suppression group in comparison with the control group, people are seen to have a shorter digit span whenasked to perform an articulatory task than when not asked to perform such a task.This shows that there is a significantdifferencein the articulatory suppression group to the control group.
