The role of physiological arousal in time perception: psychophysiological evidence from an emotion regulation paradigm

Time perception, crucial for adaptive behavior, has been shown to be altered by emotion. An arousal-dependent mechanism is proposed to account for such an effect. Yet, physiological measure of arousal related with emotional timing is still lacking. We addressed this question using skin conductance response (SCR) in an emotion regulation paradigm. Nineteen participants estimated durations of neutral and negative sounds by comparing them to a previously memorized duration. Instructions were given to attend either to temporal or to emotional stimulus features. Attending to emotion with negative sounds generated longer subjective duration and greater physiological arousal than attending to time. However, a shared-attention condition showed discrepancy between behavioral and physiological results. Supporting the idea of a link between autonomic arousal and subjective duration, our results however suggest that this relation is not as direct as was expected. Results are discussed within recent model linking time perception, emotion and awareness.     

Prospective prediction of nonsuicidal self-injury: a 1-year longitudinal study in young adults

Nonsuicidal self-injury (NSSI) has become a significant public health problem. Although numerous studies have examined cross-sectional psychological correlates of NSSI, there has been little research examining predictors of NSSI over time. The present study examined cross-sectional and longitudinal correlates of NSSI in 81 young adult self-injurers (M age = 19, 74.1% female, 51.9% Caucasian), 51 of whom were followed up 1 year later. At baseline, participants completed self-report measures of NSSI, Axis-I disorders, borderline personality disorder (BPD), and impulsivity, as well as an implicit measure of NSSI attitudes and identity. One year later, participants completed a Timeline Followback Method whereby they indicated their engagement in NSSI over the previous 12 months. Analyses replicated many known cross-sectional correlates of NSSI, including symptoms of several Axis-I disorders and BPD. However, many of these same variables failed to predict the course of NSSI over the 1-year follow-up. The only variables to prospectively predict NSSI were past NSSI (i.e., frequency, methods, and recency of NSSI), participants’ behavioral forecast of their engagement in future NSSI, and BPD features. Findings suggest that many cross-sectional correlates of NSSI may not be useful for predicting subsequent NSSI. Instead, NSSI severity and BPD features appear to best predict continued engagement in NSSI.

Peer influence and adolescent nonsuicidal self-injury: A theoretical review of mechanisms and moderators

Nonsuicidal self-injury (NSSI) is an increasingly prevalent health risk behavior among adolescents and represents a significant public health concern. Although researchers have identified numerous antecedents or risk factors that precede engagement in NSSI behaviors, few studies have examined the role of peer influence processes. Yet, recent research suggests that adolescents may be more likely to engage in NSSI when close friends or other peers engage in similar behaviors. The following paper reviews past research on peer influence effects, including potential mechanisms and moderating variables. Methodological considerations for future research on peer influence and NSSI are discussed.     

The effect of rumination on recall of emotional words: comparison of dysphoric individuals with and without a history of nonsuicidal self-injury

ABSTRACT

Prior research and theory has suggested that rumination plays a role in nonsuicidal self-injury (NSSI), and rumination increases recall of negative autobiographical information in dysphoric individuals. Across two studies, we investigated whether rumination (versus distraction) differentially influences the recall of emotional words among dysphoric persons with and without a history of NSSI. Participants encoded unpleasant, neutral, and pleasant words and then were randomly assigned to either focus on the meaning and consequences of their emotions (i.e. rumination) or unrelated thoughts (i.e. distraction) before they were asked to recall encoded words. Across the two studies, we did not find a significant effect of rumination on memory for emotional words among dysphoric people with (Studies 1 and 2) or without a history of NSSI (Study 1). We did find that people were more likely to remember neutral words as opposed to unpleasant or pleasant words across studies, regardless of rumination condition. Together, results from these two well-powered studies provide fairly compelling evidence that rumination after encoding has little to no effect on recall for emotional words in people elevated on symptoms of depression or with NSSI history. These findings can be used to refine theories of rumination and NSSI.     

Late adolescent nonsuicidal self-injury: the roles of coping style, self-esteem, and personality pathology

This study examined the relationship between late adolescent nonsuicidal self-injury (NSSI) and coping style, self-esteem, and personality pathology. Participants were 302 late adolescent (18-19-year-old) college students who completed questionnaires on self-esteem, coping style, personality disorder symptoms, and NSSI. Participants who engaged in NSSI reported more personality pathology, more maladaptive coping styles, less rational coping, and lower self-esteem than did non self-harming participants. As hypothesized, total NSSI correlated with several personality disorders, emotional coping style, and inversely related to self-esteem and adaptive coping styles. Regression equations tested several mediation models to determine whether self-esteem or coping style mediates the relationship between personality disorder symptoms and NSSI. Emotional coping and self-esteem each fully mediated the relationship between various personality disorders and NSSI in the anticipated direction. Results also indicate self-esteem, rational, detached, and emotional coping partially mediate the relationship between several personality disorders and NSSI.     

Emotion regulation in violent conflict: Reappraisal,hope, and support for humanitarian aid to the opponent in wartime

An Internet survey revealed that day-of-the-week (DOW) stereotypes (i.e., “Monday blues”, “Wednesday hump day”, “TGIF”, etc.) were pronounced when subjects predicted their moods for each day of the upcoming week, less obvious when they remembered their moods from each day of the preceding week, and least apparent in the momentary moods they actually experienced on each day. In a second study involving 2-hour, in-home interviews, subjects reporting looking forward to weekends because of the lack of structure and discipline and the freedom to choose activities, yet much of their weekend time was spent fulfilling a need to be productive, which often involved activities that, in many ways, simulated paid work. The content of these interviews suggested that people tend to overvalue future discretionary time on the weekend, assuming that two days of uninterrupted idle time will be more enjoyable than it actually is. In a more general sense, these results suggest that the predicted and remembered moods in the initial survey were driven by DOW stereotypes, which facilitated rapid judgements given the simple scaled response format. However, the depth interviews revealed that moods experienced throughout the week are more nuanced in terms of how they are remembered, described, and linked to recently passed, current, and immediately anticipated events, perhaps explaining why DOW stereotypes were less obvious in the reported momentary moods.     

Emotion regulation in violent conflict: reappraisal, hope, and support for humanitarian aid to the opponent in wartime

It is well known that negative intergroup emotions such as anger, fear, and hatred play a major role in initiating and maintaining intergroup conflicts. It is far less clear, however, what factors promote the resolution of intergroup conflicts. Using an emotion regulation- framework, we hypothesised that one form of emotion regulation-namely cognitive reappraisal-should play a salutary role in such conflicts, and be associated with increased hope as well as greater support for humanitarian aid to out-group members. To test these hypotheses, we used a nationwide survey of Jewish-Israeli adults, conducted during the war in Gaza between Israelis and Palestinians. Results obtained via structural equation modelling revealed that Israelis who regulated their negative emotions during the war through reappraisal were more supportive in providing humanitarian aid to innocent Palestinian citizens and that this relation was partially mediated by an enhanced feeling of hope.     

The processes of facilitation and inhibition in a cue-target paradigm: insight from movement trajectory deviations

Several researchers have examined the trajectories of aiming movements in cue-target paradigms to investigate the motoric and attentional underpinnings of the inhibition of return (IOR) effect. The results of separate studies have revealed inconsistent patterns of trajectory deviations. These discrepancies may have arisen because the studies used narrow ranges of cue-target onset asynchronies (CTOAs) which may have prevented the time courses of facilitation and inhibition effects to be fully assessed. The present study was designed to conduct an examination of temporal and spatial characteristics of aiming movements over a broader range of CTOAs to provide a more comprehensive assessment of the potential expression of attentional and motoric contributions to cuing effects. Participants aimed to targets which were preceded by a non-predictive cue at CTOAs of 100, 350, 850, and 1100 ms. Analysis of spatial and temporal characteristics of the movements revealed facilitatory and inhibitory cuing effects in the trajectories, but only inhibitory cuing effects in RT. Further, the inhibitory effects in RT appeared at a shorter CTOA than the inhibitory effects in trajectories. This pattern of results suggests that the inhibitory mechanisms underlying IOR affect both attention and motor systems, but that these effects are displaced in time.     

Additional evidence from a paradigm for inferring discriminative processes in children and adults

A previously developed paradigm which incorporates a correlational methodology into an experimental context was used in the present study to specify more definitely the attribute(s) underlying verbal discrimination learning under normal conditions. In the case of fifth- and sixth-grade children, it was found that frequency theory is sufficient to account for performance on the task. However, older subjects were less homogeneously reliant on the frequency attribute. While many older subjects appeared to utilize frequency cues, others adopted strategies that resulted in the utilization of attributes other than frequency.     

Examining the development of attention and executive functions in children with a novel paradigm.

The development of attention and executive functions in normal children (7-12 years) was investigated using a novel selective reaching task, which involved reaching as rapidly as possible towards a target, while at times having to ignore a distractor. The information processing paradigm allowed the measurement of various distinct dimensions of behaviour within a single task. The largest improvements in vigilance, set-shifting, response inhibition, selective attention, and impulsive responding were observed to occur between the ages of 8 and 10, with a plateau in performance between 10 and 12 years of age. These findings, consistent with a step-wise model of development, coincide with the observed developmental spurt in frontal brain functions between 7 and 10 years of age, and indicate that attention and executive functions develop in parallel. This task appears to be a useful research tool in the assessment of attention and executive functions, within a single task. Thus it may have a role in determining which cognitive functions are most affected in different childhood disorders.     

Aging, selective attention, and inhibitory processes: a psychophysiological approach.

The present study investigated the efficiency with which younger and older adults allocate attention to relevant and irrelevant stimuli. The model of attention guiding this research links the orienting response with the allocation of attention and habituation with the inhibition of the allocation of attention. We adapted a paradigm developed by Iacono and Lykken (1983) in which subjects are instructed unambiguously either to attend to or to ignore a series of innocuous tones, and the skin conductance orienting response elicited by each tone is measured. Results revealed that young subjects instructed to ignore the tones habituated more quickly than did those instructed to attend to the tones. However, older adults exhibited nondifferential orienting across the 2 instruction conditions. These results suggest an age-related deficit in the ability to inhibit attention to irrelevant stimuli.     

Conscious thoughts from reflex-like processes: A new experimental paradigm for consciousness research

The contents of our conscious mind can seem unpredictable, whimsical, and free from external control. When instructed to attend to a stimulus in a work setting, for example, one might find oneself thinking about household chores. Conscious content thus appears different in nature from reflex action. Under the appropriate conditions, reflexes occur predictably, reliably, and via external control. Despite these intuitions, theorists have proposed that, under certain conditions, conscious content resembles reflexes and arises reliably via external control. We introduce the Reflexive Imagery Task, a paradigm in which, as a function of external control, conscious content is triggered reliably and unintentionally: When instructed to not subvocalize the name of a stimulus object, participants reliably failed to suppress the set-related imagery. This stimulus-elicited content is considered ‘high-level’ content and, in terms of stages of processing, occurs late in the processing stream. We discuss the implications of this paradigm for consciousness research.     

Risk factors for nonsuicidal self‐injury in Japanese college students: The moderating role of mood regulation expectancies

Self‐injurious behavior is increasing among college students, and is common in both psychiatric and nonclinical populations. People's engaging in self‐injury is associated with childhood maltreatment, poor negative mood regulation expectancies, and depression. During times of distress, maltreated children without healthy coping strategies tend to have impairment in mood regulation, which contributes to engaging in self‐injury. This study investigated differences between nonsuicidal self‐injury (NSSI) and non‐self‐injury groups in history of childhood maltreatment, negative mood regulation expectancies, and depression in a sample of Japanese college students. We also assessed risk factors for self‐injurious behavior, including mood regulation expectancies as a moderator of the relationship between childhood maltreatment and NSSI. Participants were 313 undergraduate students, who completed anonymous self‐report questionnaires—Deliberate Self‐Harm Inventory, Child Abuse and Trauma Scale, Negative Mood Regulation Scale, and short version of the Center for Epidemiological Studies–Depression Scale. Ten percent (n = 31) of all participants had injured themselves. Consistent with past literature, participants with self‐injury history reported more severe childhood maltreatment, poorer mood regulation expectancies, and more depression, compared to non‐self‐injurers. Frequency of NSSI positively correlated with childhood maltreatment and depression, and negatively correlated with negative mood regulation expectancies. Regression analysis revealed that stronger expectancies for negative mood regulation interacted with maltreatment to predict self‐injury: More maltreatment was associated with more self‐injury, particularly among those with weaker expectancies. Results suggested childhood maltreatment, low expectancies for negative mood regulation, and depression predicted self‐injury. Consistent with our moderation hypothesis, strong expectancies for negative mood regulation buffered the effects of childhood maltreatment, reducing the risk for self‐injury.     

Functions of nonsuicidal self-injury among young women in residential care: a pilot study with the Swedish version of the Inventory of Statements about Self-Injury

Nonsuicidal self-injury (NSSI) refers to the direct and deliberate destruction of one's own body tissue in the absence of lethal intent. The Inventory of Statements about Self-Injury (ISAS) is a recently developed instrument that taps both the frequency of different forms of NSSI and the self-perceived functions of the behaviour. The purpose of the present pilot study was to use the ISAS to study the functions of self-injury in a group of women with severe forms of NSSI who were treated within Swedish residential care settings and also to compare the patients' views with their therapists' views concerning these functions. Consistent with previous research, the patients reported intrapersonal functions (e.g. affect regulation and self-punishment) as more relevant than interpersonal functions (e.g. interpersonal influence and peer bonding). The therapists' ratings differed little from the patients' self-reports, although significant differences were found for some functions: The patients rated self-care and toughness as more important than the therapists did; the therapists, on the other hand, rated interpersonal influence and the marking of distress as more relevant than the patients did. Although the present study did not contain a full validation of the Swedish version of the ISAS, the results showed good internal consistency for the interpersonal and intrapersonal factors of the Swedish version.     

Short-term memory for serial order supports vocabulary development: New evidence from a novel word learning paradigm

Although recent studies suggest a strong association between short-term memory (STM) for serial order and lexical development, the precise mechanisms linking the two domains remain to be determined. This study explored the nature of these mechanisms via a microanalysis of performance on serial order STM and novel word learning tasks. In the experiment, 6- and 7-year-old children were administered tasks maximizing STM for either item or serial order information as well as paired-associate learning tasks involving the learning of novel words, visual symbols, or familiar word pair associations. Learning abilities for novel words were specifically predicted by serial order STM abilities. A measure estimating the precision of serial order coding predicted the rate of correct repetitions and the rate of phoneme migration errors during the novel word learning process. In line with recent theoretical accounts, these results suggest that serial order STM supports vocabulary development via ordered and detailed reactivation of the novel phonological sequences that characterize new words.     

The role of nonautomatic processes in activity regulation: from Lipps to Galperin

The authors present the historical analysis of one of the central questions in psychology: how and why the nonautomatic, psychological level of regulation (in contrast to automatic physiological processes) emerges both in evolution and in everyday context of activity. They discuss several approaches (by Lipps, Groos, Stern, James, Dewey, Claparède, Pavlov, and Leontiev) that culminated in the system of ideas developed by Galperin, one of the key figures in the cultural -historical activity theory. The authors analyze the relation of Galperin's ideas to Vygotsky's theoretical framework and then focus on Galperin's account of the origin and functions of mental activity. Galperin's contribution is highly relevant for understanding the role of psychological regulation and for contemporary research on cognition, consciousness, and conscious awareness.
