Mortality salience, martyrdom, and military might: the great satan versus the axis of evil

Study 1 investigated the effect of mortality salience on support for martyrdom attacks among Iranian college students. Participants were randomly assigned to answer questions about either their own death or an aversive topic unrelated to death and then evaluated materials from fellow students who either supported or opposed martyrdom attacks against the United States. Whereas control participants preferred the student who opposed martyrdom, participants reminded of death preferred the student who supported martyrdom and indicated they were more likely to consider such activities themselves. Study 2 investigated the effect of mortality salience on American college students' support for extreme military interventions by American forces that could kill thousands of civilians. Mortality salience increased support for such measures among politically conservative but not politically liberal students. The roles of existential fear, cultural worldviews, and construing one's nation as pursing a heroic battle against evil in advocacy of violence were discussed.     

Social anxiety and problematic alcohol consumption: the mediating role of drinking motives and situations

Social anxiety is inconsistently associated with alcohol use variables. To elucidate factors that contribute to the relationship between social anxiety and problematic alcohol use, the present study investigated drinking motives and drinking situations in an undergraduate sample (N = 293). Social anxiety was significantly correlated with endorsement of enhancement drinking motives (i.e., drinking to enhance positive experiences or emotions) but not social or coping motives. Social anxiety was also correlated with endorsement of drinking in the following high-risk situations: unpleasant emotions, conflict with others, social pressure, and testing personal control. Importantly, enhancement motives and each of these drinking situations mediated the relationship between social anxiety and alcohol-related problems. Findings suggest that alcohol use to enhance positive affect or in response to these specific situations may account for the risk for alcohol-related problems among those with social anxiety.     

Development of the 24-h rest-activity pattern in human infants

The development of the 24-h rest-activity pattern was investigated in human infants under naturalistic conditions as assessed by continuous actigraphy. Seven infants and their mothers were recorded for 4 (n=1), 6 (n=5) and 12 months (n=1) after birth. Periodogram analysis of rest-activity data was performed over consecutive 10-day intervals. A weak 24-h rest-activity pattern was already present in some infants during the newborn period. The magnitude of the 24-h component in individual periodograms increased across the first months following a saturating function. The time constants of fitted saturating exponential functions--reflecting the rate of development of the 24-h pattern--ranged from 49 to 110 days (n=6) indicating a large interindividual variability. Furthermore, intraindividual variation was observed; the magnitude of the 24-h rest-activity component showed fluctuations around the trend. Miniaturized actigraphs are ideal tools for long-term longitudinal monitoring of rest-activity behavior in infants.     

Implications of direct and indirect range restriction for meta-analysis methods and findings

Range restriction in most data sets is indirect, but the meta-analysis methods used to date have applied the correction for direct range restriction to data in which range restriction is indirect. The authors show that this results in substantial undercorrections for the effects of range restriction, and they present meta-analysis methods for making accurate corrections when range restriction is indirect. Applying these methods to a well-known large-sample empirical database, the authors estimate that previous meta-analyses have underestimated the correlation between general mental ability and job performance by about 25%, indicating that this is potentially an important methodological issue in meta-analysis in general.     

The siren's call: terror management and the threat of men's sexual attraction to women

Why do sexually appealing women often attract derogation and aggression? According to terror management theory, women's sexual allure threatens to increase men's awareness of their corporeality and thus mortality. Accordingly, in Study 1 a subliminal mortality prime decreased men's but not women's attractiveness ratings of alluring women. In Study 2, mortality salience (MS) led men to downplay their sexual intent toward a sexy woman. In Study 3, MS decreased men's interest in a seductive but not a wholesome woman. In Study 4, MS decreased men's but not women's attraction to a sexy opposite-sex target. In Study 5, MS and a corporeal lust prime increased men's tolerance of aggression toward women. Discussion focuses on mortality concerns and male sexual ambivalence.     

Numbers and space: a computational model of the SNARC effect

The SNARC (spatial numerical associations of response codes) effect reflects the tendency to respond faster with the left hand to relatively small numbers and with the right hand to relatively large numbers (S. Dehaene, S. Bossini, & P. Giraux, 1993). Using computational modeling, the present article aims to provide a framework for conceptualizing the SNARC effect. In line with models of spatial stimulus-response congruency, the authors modeled the SNARC effect as the result of parallel activation of preexisting links between magnitude and spatial representation and short-term links created on the basis of task instructions. This basic dual-route model simulated all characteristics associated with the SNARC effect. In addition, 2 experiments tested and confirmed new predictions derived from the model.     

Shared spatial representations for numbers and space: the reversal of the SNARC and the Simon effects

In 4 experiments, the authors investigated the reversal of spatial congruency effects when participants concurrently practiced incompatible mapping rules (J. G. Marble & R. W. Proctor, 2000). The authors observed an effect of an explicit spatially incompatible mapping rule on the way numerical information was associated with spatial responses. The authors also observed an effect of an incompatible numerical mapping rule (if smaller than 5, press right; if larger than 5, press left) on the Simon effect. This effect was observed only when both tasks used the same effectors. The results point to a shared spatial representation for explicit spatial information (locations) and implicit spatial information (numbers).     

Anxiety symptomatology: the association with distress tolerance and anxiety sensitivity

Research focused on psychological risk factors for anxiety psychopathology has led to better conceptualization of these conditions as well as pointed toward preventative interventions. Anxiety sensitivity (AS) has been well-established as an anxiety risk factor, while distress tolerance (DT) is a related construct that has received little empirical exploration within the anxiety psychopathology literature. The current investigation sought to extend the existing literature by examining both DT and the relationship between DT and AS across a number of anxiety symptom dimensions, including panic, generalized anxiety, social anxiety, and obsessive-compulsive anxiety. Participants (N = 418) completed a number of measures that assessed DT, AS, anxiety symptomatology, and negative affect. Findings indicated that DT was uniquely associated with panic, obsessive compulsive, general worry, and social anxiety symptoms, but that DT and AS were not synergistically associated with each of these symptom dimensions. These findings indicate that an inability to tolerate emotional distress is associated with an increased vulnerability to experience certain anxiety symptoms.     

A test of the relations between avoidance of panic-related situations and substance use, substance dependence, and depression among subclinical panickers

The hypotheses that among subclinical panickers, avoidance of panic-related situations would be associated with elevated substance use levels and increased likelihood of lifetime diagnoses of substance dependence and major depressive disorder (MDD) were tested. Findings confirmed that panic-related avoidance was associated with an elevated likelihood of lifetime diagnoses of nicotine and alcohol dependence as well as MDD, but not drug dependence. Panic avoidance was also related to relatively greater daily levels of cigarette and alcohol use.
