a 2 (audio timer) x 2 (visual timer) factorial ANOVA was performed. The participants’ scores were based on how many anagrams they completed correctly. The scores of each participant were hand counted for every group. The means for each condition are shown in Figure 1. As hypothesized a significant main effect for the audio timer was found (F (1‚ 62) = 4.627‚ p = .04‚ ɳ2 = .07) with participants in the audio timer group completing fewer anagrams than participants in the visual timer group.

555 timer ic The 555 Timer IC is an integrated circuit (chip) implementing a variety of timer and multivibrator applications. The IC was designed by Hans R. Camenzind in 1970 and brought to market in 1971 by Signetics (later acquired by Philips). The original name was the SE555 (metal can)/NE555 (plastic DIP) and the part was described as "The IC Time Machine".[1] It has been claimed that the 555 gets its name from the three 5 eke resistors used in typical early implementations
