The sample is conveniente and it consists of 597 subjects (63% women). The age of the subject ranges from 18 to 70 years, with an average age of 35.58 (SD=11.29). To measure a severity of compulsive internet use Young Internet Addiction Test-Short Form; YIAT-SF was used, and Brief Coping Orientation to Problems Experienced; Brief COPE was used to measure how people cope with problems and stressful life events. Two separate hierarchical regression analyses were conducted. In both analyses, in first step the predictors were sociodemographic variables, and in second were ten types of coping strategies (Self-distraction, Active coping, Denial, Use of emotional support, Use of instrumental support, Behavioral disengagement, Venting, Positive reframing, Acceptance and Self-blame), while the criteria variables were different dimensions of internet addiction (Loss of control/Time management and Craving/Social problems). The results showed that both models are statistically significant. Significant predictor of dimension Loss of control/Time management in the first step is age (β = -.13, p = .001), and in second step are Self-distraction (β = .09, p = .018); Active coping (β = -.15, p = .001); Behavioral disengagement (β = .24, p < .001) and Self-blame (β = .13, p = .002). When it comes to Craving/Social problems, significant predictor of this variable in first step is age (β = -.11, p = .006), and in second are gender (β = .07, p = .041); Active coping (β = -.09, p = .044); Denial (β = .14, p = .001); Use of emotional support (β = -.16, p = .002) and Behavioral disengagement (β = .25, p < .001). So, based on the results, we can conclude that based on Self-distraction, Active coping, Behavioral disengagement, and Self-blame we can predict the difficulties in everyday functioning caused by internet use, but we can also predict an effect that excessive internet use could have on social relations and craving for the Internet based on Denial, Use of emotional support and Behavioral disengagement. The application of Confirmatory Factor Analysis suggested good construct validity of Young Internet Addiction Test-Short Form.

Some of the factors that can be protective against stress in the transition period of high school completion are the locus of control and perceived social support. The aim of the study is to examine whether, and to what extent, stress levels in adolescents can be predicted based on the locus of control of adolescents as well as based on perceived social support. The research examined 190 adult high school students (Nmale = 80; Nfemale = 110) from six municipalities in Serbia. The following instruments were used: Perceived Stress Scale (PSS-10), Multidimensional Scale of Perceived Social Support (MSPSS), and The Multidimensional Locus of Control (IPC). The results showed that the dimensions Internal locus of control (β = - .30, p < .000), Family support (β = -.21, p = .002) and Powerful others (β = .190, p = .020) contribute statistically significantly to explaining the level variance stress in adolescents. Considering the intergroup differences by gender, it can be concluded that boys and girls differ statistically significantly only on the variable Stress, i.e., that girls have a higher level of stress compared to boys, t (188) = -2.411, p =.017.

The concept of an internal working model is the key link in attachment theory which connects past experiences with current patterns of behavior, maintained by dysfunctional cognitive schemas developed by generalizing aversive experiences. The dark triad consists of narcissism, psychopathy and Machiavellism. The instruments used were the Family Attachment Questionnaire by Brenan et al. (1998), and Short Dark Triad (SDT3) by Jones & Paulhus (2014). The sample of the research consisted of N = 123 participants, age 20 to 63, with an average age of M = 30.41, SD = 9.06. Males formed 43% of sample. Regression analyses show that model which consists of anxiety and avoidance dimensions is significant predictor of Machiavellism, F (2,120) = 6.26, p = .003, R2 = .09, and they predict 9% of variance, as well as psychopathy, F(2,120) = 8.98, p <.000, R2 = .13, where they predict 13% of variance, but not narcissism, F(2,120) = 0.24, p = .79, R2= .01, in which model predicted only 1% of variance. Avoidance is statistically significant and positive predictor of psychopathy (β = .29, p = .003), and anxiety is statistically significant and positive predictor of Machiavellism (β = .26, p = .004), as well as psyhopathy (β = .22, p = .025). The results of study suggest that these traits are founded on an image of self as an inadequate person and the world as a hostile place, in which other persons will try to harm us if we dare to be open towards them. Manipulation and emotional insensitivity of psychopaths and Machiavelists should be interpreted as a way to reach compromise with these key beliefs and attitudes. On the other hand, narcissism did not correlate with working modes, possibly because of low levels of insight in these persons who are strongly invested in maintaining grandiose self.

The main goal of this research is to examine the relations between depressive symptoms and visual memory of specific stimuli that show emotions. We also want to examine whether the intensity of depressive symptoms is related to longer reaction time in the experimental task, as well as whether the accuracy of the emoticon’s visual memory depends on the set size. The research was conducted on a sample of 84 participants, students of Faculty of Philosophy in Banja Luka (90% female). The PHQ-9 questionnaire was used to assess depressive symptoms. Visual memory task was created in SuperLab 4.1. for Windows.The results show that there is a partial contribution of moderate depression to the accuracy of emoticon memory with sadness expression. No partial contribution of any category of depression to the memory accuracy of emoticons with the expression of happiness has been determined. A statistically significant negative correlation for the category of “sad” stimuli was obtained between the expression of depressive symptoms and the response time in the experimental task, while no statistically significant correlation was obtained for the second category of stimuli.

Existing research indicates that inferences of the dominance of social actors can be drawn based on various social cues, including facial expression of emotion. While perceived anger usually leads to an inference of high, and perceived sadness of low dominance, perceived happiness does not create such unambiguous impressions. To achieve a clearer image, the bases and level of perceived power, specifically reward power and expertise power, were taken into consideration, both of which could be either high or low. The study included 100 participants (women = 71), first and second year psychology students. The within subject 3x2x2 design was used with Expression (happiness vs. anger vs. sadness) x Bases of power (reward power vs. expert power) x Level of power (high vs. low). Dominance was a dependent variable operationalized through the semantic differential scale. The stimuli were photographs of faces, controlled for gender and age, which displayed the aforementioned facial expressions. In the case of reward power, a significant expressed emotion x level of power interaction emerged. In the case of expert power, there was only signifficant main effect of facial expression on dominance perception. The findings were analyzed according to the various expectations of the participants, formed during the process of socialization. It could be concluded that for more insight into the mechanism which lies at the core of the effect that facial expression of emotions has on perceived dominance, the profession of the perceived individual also needs to be taken into consideration.

In this context, self-reported socially unacceptable behaviour has been examined, while the resilience has been analysed with regard to two aspects in which it can be conceptualized. The first one is Ego-resiliency which is defined as a personality trait, and it is related to adaption during the inhibition or expression of emotions, in an interdependent relation to the environment in which the person is. The second aspect is resilience defined through intrapersonal and interpersonal capacities of person which affect adaptation and tolerance to stress and negative life experiences. The research has been conducted by using convenience sample of 384 respondents of high school final-year students, from Republika Srpska (BiH). The hierarchical regression analysis has been used, while the applied measurement instruments were the following: RSA - Resilience Scale for Adults, Ego-resiliency scale, the scale of anti-social behaviour, as well as scales that measure dimensions of Aggressiveness and Conscientiousness from the Big five +2 instrument. The results of the hierarchical regression analysis showed resilience as a statistically significant predictor of socially unacceptable behaviour (R = .40, R2 = .160, F(4,318) = 15.09, p = .000). When it comes to individual predictors, Conscientiousness (β = -.24, p = .000) and Aggressiveness (β = .19, p = .000) are still dominant (after the two measures of resilience are added to the model in the second step), which is followed by the resilience (RSA; β = -.16, p = .012). It is important to note that Ego-resiliency has not been identified as a statistically significant predictor of socially unacceptable behavior (β = .06, p = .342).

The following instruments were used: the revised life orientation scale (LOT-R), a brief mood introspection scale (BMIS), and eight-channel polygraph ProComp Infiniti version 4.0. Stimulus was a clip from the film “Sophie’s Choice”. Respondents watched a neutral stimulus before film clip, used as a control measure for recording the basic level of skin conductance of the respondents. The data were analysed by t-test for independent samples (for differences between optimists and pessimists) and t-test for dependent samples (for differences before and after viewing the clip). From the results we can conclude that the mood of optimists, after watching a film clip aimed at induction of unpleasant affect, changes more than the mood of pessimists (p = .000). More precisely, the mood of optimists is more “spoiled” after watching the movie clip, while the mood of pessimists does not change statistically significantly (p = .367). Skin conductance is statistically significant in both optimists (p = .001) and pessimists (p = .005). We can conclude that the induction of affect was different for these two subsamples. In view of this fact, in the subsequent papers researching affect induction, this potentially confunding variable should be taken into account.","PeriodicalId":272628,"journal":{"name":"ГОДИШЊАК ЗА ПСИХОЛОГИЈУ","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131746859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to examine whether the level of mental imagery of respondents can be predicted based on the preference of the movie genre and to explore whether there are statistically significant differences between respondents who prefer different movie genres in terms of aphantasia. The sample consisted of 925 respondents (M= 187, F= 738). Age range in the sample was from 18 to 85 (M = 31.13; SD = 10.93). The aphantasia was operationalized through VVIQ (Vividness of Visual Imagery Questionnaire), the Instrument for Measuring Favorite Movie Genres, made for the purpose of this research was also used. Data processing was performed on the overall score of aphantasia, as well as on separate scales of open and closed eyes, and after that on a subsample of men and women, but the results were not statistically significant in any case. Both aphantasia scales of open (α = 0.874) and closed eyes (α = 0.936) show high internal consistency reliability. The results show that the phenomenon of aphantasia cannot be predicted based on the preferences of movie genres (F(6, 918) = 0.91, p = .489, R2 = .006), as well as that there are no statistically significant differences in aphantasia between respondents who prefer different film genres (F (5/919) = 0.16, p = .976).

Since different results are obtained in the reverse order, based on aphantasia we can predict preferences for movie genres to a certain extent, which could speak in favor of previously done researches that claimed aphantasia is congenital.","PeriodicalId":272628,"journal":{"name":"ГОДИШЊАК ЗА ПСИХОЛОГИЈУ","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127502816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
