Smartphone users with SPA show behaviors that are similar to traditional addictive behaviors, such as Internet Gaming Disorder, which is now included in the DSM-5. Critics of SPA claim the smartphone is primarily used to access the Internet, where the user is susceptible to countless possible addictions. Still, researchers studying SPA contend that it is similar enough to other behavioral addictions, and even substance-related addictions, to warrant further study into the effects of SPA on the brain's neurological functioning. Participants Researchers recruited 48 smartphone users to participate in a study of SPA on brain activity. All participants were between 18 and 30 years old and were asked to complete the short version of the Smartphone Addiction Scale (SAS-SV, Huag et al., 2015). The researchers used the results to assign participants to the SPA group (scores over 31 for males and over 33 for females) and a control group (scores of 31 or lower for males and 33 or lower for females). Circumstances required researchers to exclude 3 participants, leaving n-21 in the SPA group and n-23 in the control group. Method The study was approved by the Ethics Committee of the Medical Faculty at Heidelberg University. Participants received €30 (Euro) for participating. Participants' brains were scanned using an fMRI machine after being instructed to keep their eyes closed, not fall asleep, and to not think about anything in particular. Brain structure was measured by Grey Matter Volume (GMV) and brain functioning was measured by Amplitude of Low Frequency Fluctuations (ALFF). Results and Discussion Individuals with SPA showed lower GMV in three different left hemispheric brain locations when compared to the control group (p < 0.001) Additionally, individuals in the SPA group also showed lower ALFF in the left hemisphere. There were no individuals in the SPA group that showed an increase of ALFF in any brain region. Lower GMV and ALFF were both found in the same part of the brain, the left anterior insula. The insula has been strongly linked with addictive behaviors (Zhang et al., 2016). This brain region is part of the reward system and is associated with craving. Those with substance abuse disorders, for example, show lower mass and functioning in this brain region. Information from: Horfath, J. Mundinger, et al, (2020).

(06.01 HC) Cоne W hаs а rаdius оf 10 cm and a height оf 5 cm. Square pyramid X has the same base area and height as cone W.Paul and Manuel disagree on how the volumes of cone W and square pyramid X are related. Examine their arguments. Which statement explains whose argument is correct and why? Paul Manuel The volume of square pyramid X is three times the volume of cone W. This can be proven by finding the base area and volume of cone W, along with the volume of square pyramid X. The base area of cone W is π(r2) = π(102) = 314 cm2. The volume of cone W is (area of base)(h) = (314)(5) = 523.33 cm3. The volume of square pyramid X is (area of base)(h) = (314)(5) = 1,570 cm3. The volume of square pyramid X is equal to the volume of cone W. This can be proven by finding the base area and volume of cone W, along with the volume of square pyramid X. The base area of cone W is π(r2) = π(102) = 314 cm2. The volume of cone W is (area of base)(h) = (314)(5) = 523.33 cm3. The volume of square pyramid X is (area of base)(h) = (314)(5) = 523.33 cm3.
