Abstract. Generalized anxiety disorder (GAD) is associated with worry and emotion regulation difficulties. The contrast-avoidance model suggests that individuals with GAD use worry to regulate emotion: by worrying, they maintain a constant state of negative affect (NA), avoiding a feared sudden shift into NA. We tested an extension of this model to positive affect (PA). During a week-long ecological momentary assessment (EMA) period, 96 undergraduates with a GAD analog provided four daily measurements of worry, dampening (i.e., PA suppression), and PA. We hypothesized a time-lagged mediation relationship in which higher worry predicts later dampening, and dampening predicts subsequently lower PA. A lag-2 structural equation model was fit to the group-aggregated data and to each individual time-series to test this hypothesis. Although worry and PA were negatively correlated in 87 participants, our model was not supported at the nomothetic level. However, idiographically, our model was well-fit for about a third (38.5%) of participants. We then used automatic search as an idiographic exploratory procedure to detect other time-lagged relationships between these constructs. While 46 individuals exhibited some cross-lagged relationships, no clear pattern emerged across participants. An alternative hypothesis about the speed of the relationship between variables is discussed using contemporaneous correlations of worry, dampening, and PA. Findings suggest heterogeneity in the function of worry as a regulatory strategy, and the importance of temporal scale for detection of time-lagged effects.

The objective of this study is to measure whether there is or not significant effect of teaching reading by utilizing Hot Potatoes software toward students’ reading comprehension of descriptive text. The variables used were the teaching treatment of Hot Potatoes Software as the independent variable and the students’ reading comprehension of Descriptive Text as dependent variable. Then, the research designed was Quasi-experimental design and the presentation of data used was quantitative. The data were obtained from the eleventh grade, of which 28 students were taken as sample. The students are divided into two groups; experiment group consisted of 12 students and control group consists of 16 students. To get the data, the pre-test and post-test were applied and then analyzed using t-test formula. The researcher had concluded that there is Significant effect of Hot Potatoes Software toward the students’ reading comprehension achievement. The result showed that mean of students’ post-test was increased. It is proved by the t-test (8.54) which is higher than t-table (2.05) at level of significance 5%. It means that the alternative hypothesis was accepted and it proved that Hot Potatoes Software had significant effect toward students’ reading comprehension of Descriptive Text

This study is aimed at finding out the effect of Collaborative Strategic Reading (CSR) on students’ achievement in reading comprehension on hortatory exposition text. Experimental design was applied in this research. The population was the 2014/2015 second year students (grade XI) of SMA Swasta YAPIM Medan. There were two paralel classes that consisted of 34 students. The total number of the population were 68 students. The total number of the sample were 68 students. The researcher selected the sample by using total sampling technique. The sample was divided into two groups, experimental group and control group. The experimental group was taught by using Collaborative Strategic Reading (CSR) strategy while the control group was taught without using Collaborative Strategic Reading (CSR) strategy. The data were taken by administering the pre-test and post-test to both control and experimental groups. These data were analyzed by using t-test. The result of computing the t-test obviously showed that t-observed (5.61) is higher than t-table (1.99) with the degree of freedom (df= 66) at the level significance 0.05. It means that the alternative hypothesis stating that there is a significant effect of Collaborative Strategic Reading (CSR) on students’ achievement in reading comprehension on hortatory exposition text is accepted.
