The mere presence of a smartphone reduces basal attentional performance

This dataset contains the relevant data for the study “The mere presence of a smartphone reduces basal attentional performance”. 

The following variables are presented:

Person: Numbering of the test subjects

Gender: 1- male; 2- female

Age: Age of the test subjects

Question1 - Question10: The checked values by the test subjects of the questionnaire d-KV-SSS (German Short Version of the Smartphone Questionnaire)

WithWithout: The conduction of the test in smartphone presence (with- 1) and out of smartphone presence (without- 2) 

Values of the attention test (d2-R):

APValue: The attention performance value; a person's ability to focus their attention

PTOValue: The “Processed target objects” value that indicates the speed of the test processing  

E% value: The Error % value, the accuracy of a test person in processing the d2-R

ValidInvalid: Valid or invalid test performance

SmartphoneDependenceSum: The summed-up values of the questionnaire (Question 1 to Question 10), thus the results of the questionnaire d-KV-SSS that indicate a possible tendency towards a smartphone dependency

In our study, it was hypothesized that there is a lower attentional performance under smartphone presence. To test this hypothesis, three one-tailed ANOVAs were conducted with the presence and absence of the smartphone as the independent variable and one of the three given values of the d2-R (attention performance, speed value and error value) as the dependent variable. 

The total score of the d-KV-SSS (“SmartphoneDependenceSum”) indicates a tendency towards smartphone dependence. A one-factor ANOVA was used to examine the subjects' attention performance in connection with a tendency towards smartphone addiction. The presence or absence of the smartphone was the independent variable, and the attention performance score was the dependent variable.
