Rumination and the Displacement of Aggression in United Kingdom Gang‐Affiliated Youth

The concept of gang aggression oftentimes elicits images of brutal intergang violence. In reality, gang‐related aggression can vary widely, can have various motivations and causal factors, and includes interpersonal as well as intergroup aggression. This study examined the tendency of UK youth to engage in displaced aggression (aggression aimed at undeserving targets) and examined the relationship among gang affiliation, ruminative thought, and aggression levels. Students in three London schools were asked to complete a questionnaire that assessed levels of gang affiliation, rumination about aversive events, and a tendency to engage in displaced aggression. Our analyses found a three‐way interaction between gang affiliation, rumination, and gender, such that males who were high in affiliation and rumination had the greatest tendency to displace aggression toward innocent others. Additionally, it was shown that rumination could account for a significant part of the correlation between gang affiliation and displaced aggression. Furthermore, regression analyses showed that even after controlling for trait aggression, anger, hostility, and irritability, rumination remained a significant predictor of displaced aggression. The implications for understanding gang‐related aggression and for conducting future research in this area were discussed. Aggr. Behav. 38:89‐97, 2012. © 2011 Wiley Periodicals, Inc.     

Emotional self-efficacy moderates anxiety-related impairments in math performance in elementary school-age youth

Excessive anxiety is associated with impairments in academic achievement. However, not all children with elevated anxiety share an equal risk for academic difficulty. The current study investigated whether individual differences in emotional self-efficacy - confidence in one’s ability to regulate negative emotions - protected against anxiety-related impairments in a standardized math exam in a sample of elementary school youth (N = 139). Results indicated that anxiety negatively predicted math test performance only for children with low levels of emotional self-efficacy. Students reporting high levels of emotional self-efficacy did not show anxiety-related decrements on the test performance. Emotional self-efficacy appears useful in managing negative effects of anxiety.     

Positive and negative appraisals of the consequences of activated states uniquely relate to symptoms of hypomania and depression

Individuals may appraise internal states positively or negatively. Positive appraisals involve desiring or pursuing the state or experience, while negative appraisals involve dreading or avoiding the experience. The extent to which individuals make extreme positive or negative appraisals of high, activated, energetic states might determine whether they experience symptoms of high or low mood. This study extends the existing literature by considering the role of opposing appraisals and beliefs about the same internal states and by controlling for the potential correlation between depression and activation symptoms. Extreme, positive and negative appraisals of activated mood states related distinctly to experiences of activation and depression symptoms respectively, in an analogue sample (n=323). Positive appraisals of activated internal states were uniquely associated with elevated activation and hypomania symptoms. Negative appraisals of the same states were uniquely associated with elevated depression symptoms. Opposing appraisals of internal states may underlie mood swing symptoms.     

Habits—A Repeat Performance

ABSTRACT— Habits are response dispositions that are activated automatically by the context cues that co-occurred with responses during past performance. Experience-sampling diary studies indicate that much of everyday action is characterized by habitual repetition. We consider various mechanisms that could underlie the habitual control of action, and we conclude that direct cuing and motivated contexts best account for the characteristic features of habit responding—in particular, for the rigid repetition of action that can be initiated without intention and that runs to completion with minimal conscious control. We explain the utility of contemporary habit research for issues central to psychology, especially for behavior prediction, behavior change, and self-regulation.     

Algorithms for fast and precise computation of the normal integral

Five highly accurate algorithms that evaluate the normal distribution function are presented. The algorithms, which are based on either numerical integration or series expansions, are explicated, and applications of Simpson’s rule are discussed. Computer programs that implement the algorithms were compared with respect to accuracy and speed. The programs attain from 11- to 15-decimal-place accuracy in finding one-tailed areas of the normal curve, and most execute very quickly. Recommendations are made for selection of algorithms and programs to approximate the normal distribution.     

Access to attitude-relevant information in memory as a determinant of persuasion: The role of message attributes

Recipients with access to attitude-relevant information in memory were thought to draw on these beliefs and prior experiences to evaluate the validity of message arguments. Consistent with this idea, persuasion for these recipients was largely a function of the perceived validity of message content: Messages containing high-quality arguments were more persuasive than messages containing lowquality arguments, whereas variations in a structural attribute of the message (its length) proved to have little impact on opinion change. In contrast, people who tend to retrieve little attitude-relevant information were believed to be less able to evaluate the validity of message arguments in terms of information accessed from memory. Instead, it was anticipated that they would base their opinion judgments on a more superficial analysis of persuasion cues, focusing on attributes like message length. Consistent with this reasoning, these recipients were more persuaded by long than short messages. Recipients with moderate levels of retrieval functioned much like the high-retrieval subjects.     

The prevalence of nightmares and their independence from anxiety

Although several studies have examined the prevalence of nightmares and their relationship to anxiety, this is the first to have used daily dream logs, rather than retrospective self-reports, to monitor nightmare frequency. 220 undergraduates were administered self-report measures of anxiety and for 2 weeks recorded the number of their nightmares in logs. 47% of Ss reported at least one nightmare during the study period. The dream logs yielded an estimated mean annual nightmare frequency of 23.6, which is 2.5 times as great as the estimate yielded by retrospective reports (p less than .01). Nightmare frequency and anxiety were uncorrelated. The findings indicate that nightmares are more prevalent than has been reported, and their frequency unrelated to self-reported anxiety.     

An Hebrew language version of the Stroop test

We present normative data from a Hebrew language version of the Stroop color-word test. In this sample of college-educated Israeli young adults, 18 women and 28 men with a mean age of 28.4 yr. completed a Hebrew language Stroop test. When compared with 1978 English language norms of Golden, Hebrew speakers were slower on color-word reading and color naming, similar on naming the color of incongruently colored names of colors, and showed less interference. Slowed color-word reading and color-naming may reflect the two-syllable length of the Hebrew names for one-syllable length English language colors; reduced interference may reflect the exclusion of vowels in much Hebrew printing and subjects' ability to provide competing, nonconflicting words while naming the color of words in which the hue and the lexical content do not match.     

Auditory and phonetic levels of processing in speech perception: neurophysiological and information-processing analyses.

Two new experimental operations were used to distinguish between auditory and phonetic levels of processing in speech perception: the first based on reaction time data in speeded classification tasks with synthetic speech stimuli, and the second based on average evoked potentials recorded concurrently in the same tasks. Each of four experiments compared the processing of two different dimensions of the same synthetic consonant-vowel syllables. When a phonetic dimensions was compared to an auditory dimension, different patterns of results were obtained in both the reaction time and evoked potential data. No such differences were obtained for isolated acoustic components of the phonetic dimension or for two purely auditory dimensions. Together with other recent evidence, the present results constitute additional converging operations on the distinction between auditory and phonetic processes in speech perception and on the idea that phonetic processing involves mechanisms that are lateralized in one cerebral hemisphere.     

When are semantic targets detected faster than visual or acoustic ones?

Duration-discrimination data from an experiment using empty auditory intervals in a two-alternative forced-choice paradigm are presented. The observed functional relationship between standard deviation of the psychometric density function and stimulus duration is shown to be fit significantly better by a Weber’s law model of duration discrimination than by Creelman’s counter model. Both models fail to predict the rapid rise in the Weber fraction observed for durations longer than about 2 sec. However, the Weber’s law model, based on a generalization of Weber’s law, accurately predicts the initial drop in the Weber fraction for very short durations and the observed constancy of the Weber fraction for durations up to 2 sec.
