An Examination of Post-Traumatic Stress Symptoms and Aggression among Children with a History of Adverse Childhood Experiences

Childhood aggression is associated with many deleterious outcomes and is a common reason for psychiatric referral (Card & Little, 2006; Gurnani et al., 2016). One factor associated with childhood aggression is Adverse Childhood Experiences (ACEs; Felitti et al., 1998). However, existing research remains equivocal on which characteristics of ACEs (e.g., cumulative impact, typology, etc.) are significantly elated to aggression, especially when considering differential effects of ACEs on proactive aggression (PA) and reactive aggression (RA; Dodge & Coie, 1987). Post-traumatic stress symptoms (PTSS) are a common negative sequalae of ACEs and are characterized by disruptions in several cognitive, emotional, and behavioral processes similar to those associated with both RA and PA (e.g., Marsee, 2008). As such, the examination of PTSS as an underlying mechanism of influence on the relation between ACEs, PA, and RA is warranted. The present study fills several gaps in the literature by examining ACE characteristics that might be related to PTSS, PA, and RA while also examining direct and indirect effects on the relation between ACEs, PTSS and PA and RA. Results indicated the type of ACE, specifically child maltreatment ACEs (CM-ACEs), was most strongly related to all outcome variables. Therefore, CM-ACEs were included in a path analysis with PTSS, PA, and RA. Results indicated a significant indirect effect for PTSS on the relation between CM-ACEs and RA (β?=?.18, p?<?.01) but not PA. Findings have several implications for future research and clinical practice, especially for children with an extensive history of CM-ACEs.

     

Assessing students' use of optional online lecture reviews

Online practice quizzes can be used to supplement instruction in the classroom. Such quizzes can engage retrieval practice, thereby improving learning and retention. However, despite their potential benefits, recent work suggests that students typically underutilize online practice quizzes. This article reports an observational classroom study, in which students were provided optional online reviews throughout the semester. The reviews could be accessed in test format, in which students were given multiple-choice questions and provided correct answer feedback, or in read format in which students were given the same questions and were shown the correct answers. Students who used the test format performed better on exams than students who used the read format or did not use the reviews. Nevertheless, the massive majority of the online reviews (approximately 88%) were not completed, highlighting the tendency for students to underutilize optional online reviews.     

Muslims’ emotions toward Americans predict support for Hezbollah and Al Qaeda for threat-specific reasons

Using a random sample of 243 Muslims in Lebanon and Syria, we examined whether support for Hezbollah or for Al Qaeda is predicted by functionally-relevant emotional responses to specific threats perceived to be posed by Americans. In line with the sociofunctional approach, perceived resource domination threat from Americans elicited anger, and perceived value contamination threat elicited disgust/contempt toward Americans. Importantly, these intergroup emotions in turn differentially predicted support for Hezbollah and Al Qaeda through desires for the organizations to accomplish different goals to address the threat perceptions. Specifically, anger toward Americans predicted support for Hezbollah through desires for the organization to restore threatened symbolic resources by bringing pride and respect to Arabs. In contrast, disgust/contempt toward Americans predicted support for Al Qaeda through desires for the organization to protect threatened ingroup values by de-contaminating Islam from Western cultural influence. Theoretical explanations and implications for addressing and mitigating hostilities between the groups are discussed.     

Are pictures good for learning new vocabulary in a foreign language? Only if you think they are not

The current study explored whether new words in a foreign language are learned better from pictures than from native language translations. In both between-subjects and within-subject designs, Swahili words were not learned better from pictures than from English translations (Experiments 1-3). Judgments of learning revealed that participants exhibited greater overconfidence in their ability to recall a Swahili word from a picture than from a translation (Experiments 2-3), and Swahili words were also considered easier to process when paired with pictures rather than translations (Experiment 4). When this overconfidence bias was eliminated through retrieval practice (Experiment 2) and instructions warning participants to not be overconfident (Experiment 3), Swahili words were learned better from pictures than from translations. It appears, therefore, that pictures can facilitate learning of foreign language vocabulary--as long as participants are not too overconfident in the power of a picture to help them learn a new word.     

Social dominance theory and the dynamics of intergroup relations: Taking stock and looking forward

This chapter reviews the last 15 years of research inspired by social dominance theory, a general theory of societal group-based inequality. In doing so, we sketch the broad outlines of the theory and discuss some of the controversies surrounding it, such as the “invariance hypothesis” regarding gender differences in social dominance orientation (SDO) and the effect of social context on the expression of SDO. We also discuss the central role of gender in the construction and maintenance of group-based inequality, and review some of the new research inspired by the social dominance perspective. Finally, we identify and discuss some of the most important theoretical questions posed by social dominance theory that are yet to be researched.     

The effects of interleaving versus blocking on foreign language pronunciation learning

Many studies have shown that students learn better when they are given repeated exposures to different concepts in a way that is shuffled or interleaved, rather than blocked (e.g., Rohrer Educational Psychology Review, 24, 355–367, 2012). The present study explored the effects of interleaving versus blocking on learning French pronunciations. Native English speakers learned several French words that conformed to specific pronunciation rules (e.g., the long “o” sound formed by the letter combination “eau,” as in bateau), and these rules were presented either in blocked fashion (bateau, carreau, fardeau . . . mouton, genou, verrou . . . tandis, verglas, admis) or in interleaved fashion (bateau, mouton, tandis, carreau, genou, verglas . . .). Blocking versus interleaving was manipulated within subjects (Experiments 1–3) or between subjects (Experiment 4), and participants’ pronunciation proficiency was later tested through multiple-choice tests (Experiments 1, 2, and 4) or a recall test (Experiment 3). In all experiments, blocking benefited the learning of pronunciations more than did interleaving, and this was true whether participants learned only 4 words per rule (Experiments 1–3) or 15 words per rule (Experiment 4). Theoretical implications of these findings are discussed.     

Semantic information activated during retrieval contributes to later retention: Support for the mediator effectiveness hypothesis of the testing effect

Previous research has proposed that tests enhance retention more than do restudy opportunities because they promote the effectiveness of mediating information--that is, a word or concept that links a cue to a target (Pyc & Rawson, 2010). Although testing has been shown to promote retention of mediating information that participants were asked to generate, it is unknown what type of mediators are spontaneously activated during testing and how these contribute to later retention. In the current study, participants learned cue-target pairs through testing (e.g., Mother: _____) or restudying (e.g., Mother: Child) and were later tested on these items in addition to a never-before-presented item that was strongly associated with the cue (e.g., Father)--that is, the semantic mediator. Compared with participants who learned the items through restudying, those who learned the items through testing exhibited higher false alarm rates to semantic mediators on a final recognition test (Experiment 1) and were also more likely to recall the correct target from the semantic mediator on a final cued recall test (Experiment 2). These results support the mediator effectiveness hypothesis and demonstrate that semantically related information may be 1 type of natural mediator that is activated during testing.     

Social Dominance Orientation, Authoritarianism, and Support for Intergroup Violence Between the Middle East and America

Social dominance theory has generally posited that terror and intergroup violence can be explained in terms of social dominance struggles. Social dominance theorists have described terror mostly as a tool for maintaining intergroup hierarchies in society (Sidanius & Pratto, 1999). Although implications of the theory suggest that terror may also be used by lower status groups as a tool for the resistance of domination by higher status groups, this prediction heretofore has not been empirically demonstrated. Data from two samples, one in the United States and one in Lebanon, were collected regarding attitudes toward terrorism and intergroup violence. The results show that the American sample demonstrates the typical patterns of social dominance such that those who are higher in social dominance orientation tend to support greater violence toward the Middle East. However, the Lebanese sample shows the opposite pattern, such that those who are lower in social dominance orientation tend to support violence toward the West. These results suggest that (1) support for terrorism among Middle East citizens is a project of counterdominance, and, more broadly, that (2) the relationship between social dominance orientation and support for violence depends on the dynamics of the conflict and the status of the perpetrators.     

The effect of university roommate contact on ethnic attitudes and behavior

This study examined the effect of living with White, Asian American, Latino, or African American roommates on affective, cognitive, and behavioral indicators of prejudice among university students. We used a five-wave panel study with approximately 2000 students to examine the effect of roommate contact in two ways: First, through a field experimental test by examining prejudice as a function of living with randomly assigned roommates during the first year of university. Second, net of pre-existing attitudes, we examined the effects of voluntary roommate contact during the second and third year of university on fourth year prejudice. Consistent with contact theory, both randomly assigned and voluntary contact decreased prejudice. Also, there was generalization to other outgroups, particularly from Black roommates to Latinos, and vice versa. Finally, an interesting exception was found for contact with Asian American roommates, whether randomly assigned or voluntary, which tended to make attitudes towards other groups more negative. Potential explanations for this result are discussed.
