Emotion regulation and intimate partner violence in newlyweds

Is the inability to regulate negative emotions a risk factor for intimate partner violence (IPV)? To address this question, the authors asked 72 newlywed couples to report their levels of negative affect every day for 7 days and examined whether variability in those reports was associated with the IPV self-reported to have been perpetrated over the previous year. Although main effects of variability in both husbands' and wives' negative affect did not reach statistical significance, variability in husbands' negative affect significantly interacted with wives' reports of IPV to account for husbands' IPV, even after overall levels of husbands' negative affect, marital satisfaction, and chronic stress were controlled. Specifically, whereas variability in negative affect was unrelated to IPV among husbands with wives who reported no IPV, such variability was positively associated with the IPV perpetrated by husbands with wives who also reported having perpetrated IPV during the previous year. Although preliminary, these results support theories suggesting that the ability to regulate negative emotions may help intimates avoid perpetrating IPV, particularly when faced with a partner's IPV perpetration.     

Neuroticism, marital violence, and the moderating role of stress and behavioral skills

Do high levels of neuroticism predict intimate partner violence (IPV)? Although neuroticism may predispose partners to increased risks of IPV perpetration, the extent to which it predicts such perpetration is likely to depend on the broader context of the relationship. Consistent with this prediction, the current longitudinal study of 169 community couples revealed that the effects of neuroticism on IPV perpetration over the first 4 years of marriage were moderated by observations of problem-solving behavior and objective ratings of chronic stress. Specifically, although husbands and wives who scored higher on a measure of neuroticism at the outset of marriage engaged in more IPV throughout the marriage on average, those who possessed more effective problem-solving skills or experienced lower levels of stress were significantly less likely to engage in IPV. Results highlight the importance of considering the broader relationship context when examining predictors of specific interpersonal processes.     

Shedding light on words and sentences: near-infrared spectroscopy in language research

Investigating the neuronal network underlying language processing may contribute to a better understanding of how the brain masters this complex cognitive function with surprising ease and how language is acquired at a fast pace in infancy. Modern neuroimaging methods permit to visualize the evolvement and the function of the language network. The present paper focuses on a specific methodology, functional near-infrared spectroscopy (fNIRS), providing an overview over studies on auditory language processing and acquisition. The methodology detects oxygenation changes elicited by functional activation of the cerebral cortex. The main advantages for research on auditory language processing and its development during infancy are an undemanding application, the lack of instrumental noise, and its potential to simultaneously register electrophysiological responses. Also it constitutes an innovative approach for studying developmental issues in infants and children. The review will focus on studies on word and sentence processing including research in infants and adults.     

The role of drug use in a conceptual model of intimate partner violence in men and women arrested for domestic violence.

In a previous study, alcohol problems in perpetrators and their partners contributed directly and indirectly to intimate partner violence (IPV), even after including other correlates of violence in the model (G. L. Stuart et al., 2006). The present study extends these findings by examining the role of illicit drug use. We recruited 271 men and 135 women arrested for IPV and used structural equation modeling to examine the data. Results showed that drug use, as reported by the perpetrators, was a stronger predictor of IPV than were alcohol problems in perpetrators and their partners. Arrested males' marijuana use and stimulant use (i.e., cocaine and amphetamines) were associated with perpetration of IPV, and their report of their female partners' stimulant use was associated with her violence perpetration. In arrested women, specific substances used did not predict violence perpetration beyond other model variables; however, female perpetrators' report of male partners' stimulant use predicted male psychological and physical aggression, after controlling for other variables. These results provide further evidence that drug problems by both partners may be important in the evolution of aggression. Implications for batterer intervention programs are discussed.     

The reward probability index: design and validation of a scale measuring access to environmental reward

Behavioral models of depression implicate decreased response-contingent positive reinforcement (RCPR) as critical toward the development and maintenance of depression (Lewinsohn, 1974). Given the absence of a psychometrically sound self-report measure of RCPR, the Reward Probability Index (RPI) was developed to measure access to environmental reward and to approximate actual RCPR. In Study 1 (n = 269), exploratory factor analysis supported a 20-item two-factor model (Reward Probability, Environmental Suppressors) with strong internal consistency (α = .90). In Study 2 (n = 281), confirmatory factor analysis supported this two-factor structure and convergent validity was established through strong correlations between the RPI and measures of activity, avoidance, reinforcement, and depression (r = .65 to .81). Discriminant validity was supported via smaller correlations between the RPI and measures of social support and somatic anxiety (r = – .29 to – .40). Two-week test–retest reliability was strong (r = .69). In Study 3 (n = 33), controlling for depression symptoms, hierarchical regression supported the incremental validity of the RPI in predicting daily diary reports of environmental reward. The RPI represents a parsimonious, reliable, and valid measure that may facilitate understanding of the etiology of depression and its relationship to overt behaviors.     

Electrophysiological evidence for modulation of lexical processing after repetitive exposure to foreign phonotactic rules

In two experiments we investigate how repeated exposure to native and non-native phonotactic regularities alters the N400, an event-related potential related to lexico-semantic access. Participants underwent a Passive Listening (Experiment 1) or a Categorization Training (Experiment 2) for monosyllabic pseudowords over 3 days. During Passive Listening participants solely listened to the stimuli while for Categorization Training they learned to assign items to two arbitrary categories by feedback. Notably, this task did not rely on phonotactic regularities. Before training, N400 was larger for legal compared to illegal items. Over the 3-day exposure Passive Listening yielded a significant decrease in N400-amplitude for illegal pseudowords, however, this effect was abolished and partially inverted by the Categorization Training. We suggest the decrease in N400-amplitude indicates more efficient discrimination between native and non-native pseudowords since only the former are potential lexical candidates. On the contrary, Categorization Training introduces a ‘protosemantic’ context overriding prelexical selection processes.     

EEG Aspects of Cognitive Processes: A Contribution to the Proteus-like Nature of Consciousness

Probability mapping of amplitude and coherence based on spectral analysis yields information on the cooperation of brain areas in cognitive processes. The method is based on comparing these two parameters during the performance of a mental task with the respective values of the EEG at rest. For each of 6 frequency bands spanning the entire EEG spectrum the data are represented on schematic brain maps with significant changes of amplitude (entered at the sites of the 19 electrodes) and coherence (between all respective electrodes). These maps have proven to be largely task-specific in both group and individual studies. They are considered to objectify electrical manifestations of differential attention.
