Memory-load interference in syntactic processing

Participants remembered a short set of words while reading syntactically complex sentences (object–extracted clefts) and syntactically simpler sentences (subject–extracted clefts) in a memory–load study. The study also manipulated whether the words in the set and the words in the sentence were of matched or unmatched types (common nouns vs. proper names). Performance in sentence comprehension was worse for complex sentences than for simpler sentences, and this effect was greater when the type of words in the memory load matched the type of words in the sentence. These results indicate that syntactic processing is not modular, instead suggesting that it relies on working memory resources that are used for other nonsyntactic processes. Further, the results indicate that similarity–based interference is an important constraint on information processing that can be overcome to some degree during language comprehension by using the coherence of language to construct integrated representations of meaning.     

Development and validation of a modified version of the Peritraumatic Dissociative Experiences Questionnaire

This article reports results from 3 studies conducted to develop and validate a modified version of the self-administered form of the Peritraumatic Dissociative Experiences Questionnaire (PDEQ; C. R. Marmar, D. S. Weiss, & T. J. Metzler, 1997). The objective was to develop an instrument suitable for use with persons from diverse ethnic and socioeconomic backgrounds. In Study 1, the original PDEQ was administered to a small sample (N = 15) recruited from among men admitted to the hospital for physical injuries stemming from exposure to community violence. Results led to modifications aimed at improving the utility of the instrument. In Study 2, the modified PDEQ was subjected to structural equation modeling and item response theory analyses to assess its psychometric properties in a larger, primarily male, sample of community violence survivors (N = 284). In Study 3, the reliability and validity of the modified instrument were further assessed in a sample of female survivors of sexual assault (N = 90). Results attest to the psychometric properties as well as the reliability and validity of the modified 8-item PDEQ.     

Attention-Deficit/Hyperactivity Disorder and methylphenidate: a dose-response analysis and parent-child comparison of somatic complaints

The authors examined parent and child ratings of somatic complaints in 65 children with Attention-Deficit/Hyperactivity Disorder (ADHD) who received four doses (5 mg, 10 mg, 15 mg, 20 mg) of methylphenidate (MPH) in the context of a double-blind, placebo controlled, within-subject (crossover) experimental design. Results indicated that parent and child ratings of somatic complaints decreased in a linear fashion from baseline levels as a function of increasing MPH dose and showed minimal variation across MPH conditions. Statistical comparisons of specific somatic complaints indicated minimal agreement between parents and children in contrast to the nearly identical parent-child dose-response curves. The paradoxical findings of fewer somatic complaints associated with MPH, importance of obtaining children's perceptions of MPH treatment, and implications for measuring somatic complaints are discussed.     

If we had known then what we know now: a review of local and national surveys following September 11, 2001

There is little research on the consequences of large-scale violent disasters in a community despite their unfortunate prevalence over many decades. The primary source of epidemiological data for the greater New York community in dealing with the September 11, 2001, attacks was the Oklahoma City bombing. In the latter event, 45%; of directly exposed adults met criteria for a major psychiatric disorder 6 months later, including 34%; with posttraumatic stress disorder (PTSD). The first survey after the World Trade Center and Pentagon attacks, conducted within one week, revealed a remarkable degree of symptomatology across the nation in both adults and children. Forty-four percent of adults reported at least 1 of 5 PTSD screening symptoms in the 3-5 days after the attacks; 35% of parents reported children who had at least one symptom, and 47% of children worried about their own or someone else's safety. Coping behaviors were consistent with a community mental health model and included turning to open discussion (98%), religion (90%), and community activities (60%) in order to cope with their reactions. Rates of disorder were also high in a survey conducted 5-8 weeks later in Manhattan below 110th Street, with 38% saying they directly witnessed the World Trade Center attack. The current prevalence of new-onset PTSD was 7.5%, and of new-onset major depressive disorder, 9.7%. This translates into 67,000 persons with PTSD and 87,000 persons with major depression. This survey also found a significant increase in tobacco, alcohol, and marijuana use, but primarily among adults already using these substances. All surveys found strong associations between media exposure and symptomatology. The greatest need at this point in the literature is therapeutics research after such traumatic events.     

Individual differences in working memory capacity and enumeration

Two experiments are reported in which subjects performed working memory and enumeration tasks. In the first experiment, subjects scoring low on the working memory task also performed poorly on the attention-demanding "counting" portion of the enumeration task. Yet no span differences were found for the non-attention-demanding "subitizing" portion. In Experiment 2, conjunctive and disjunctive distractors were added to the enumeration task. Although both high and low working memory span subjects were adversely affected by the addition of conjunctive distractors, the effect was much greater for the low-span subjects. Implications from these findings are that differences in working memory capacity correspond to differences in capability for controlled attention.     

Editorial synthesis for 2 in 2023 a collaboration between IARR's two journals: Recognizing the need for greater inclusivity in relationship science

The idea for this special issue came from the current Editors of the Journal for Social and Personal Relationships and Personal Relationships, who wanted to forge a collaboration between the International Association for Relationship Research's two journals. The timing of such collaboration came at a time when issues surrounding diversity, equity, and inclusion were being brought to light in science, broadly defined. Stemming from such discussions, for this special issue, we asked 10 sets of authors to apply an intersectional lens—grounded in Crenshaw's (1989, 1991) definition of intersectionality and drawing from questions posed by Cole (2009)—in their systematic review of literature from the past 20 years (1992–2022) and to answer these three questions: (1) from whose vantage point is the research being conducted, (2) what types of questions are valued, and (3) who is included in the research vs. who is being left out/whose voices are missing. Reviews for the special issue include these topics: (a) affectionate communication, health, and relationships, (b) romantic relationship maintenance behaviors, (c) relationship maintenance among military couples, (d) relational sacrifices, (e) LGBTQ-inclusive research, (f) stress, support, and coping for romantic couples, (g) daily stress and romantic relationship quality, (h) infidelity, (i) relationship dissolution, and (j) the longitudinal study of romantic close relationships. Across the reviews, authors noted many of the same patterns; most studies included samples from the United States, wherein participants identified as White, heterosexual, and/or female; however, military samples were dominated by men. The methods employed were largely quantitative, cross-sectional, and/or with data coming from surveys. Observations during the review process included the role of positionality as well as greater knowledge gained about the critical framework of intersectionality, specifically acknowledging that elements of diversity in sampling methods are not an application of intersectionality; rather, intersectionality places central focus on (a) how multiply marginalized social identities have been historically oppressed and (b) how systems of power, oppression, and privilege construct, reproduce, and sustain those multiply marginalized social identities. Recommendations for future relationship science are presented, specifically in how our fields can benefit from learning from the lens of intersectionality.     

Partners' internal stress and well-being: The role of dyadic coping and problem resolution

Couples' experiences of daily stress can be detrimental for partners' individual and relational well-being, specifically their identity as a couple, their relational satisfaction, and their life satisfaction. Grounded in the Systemic Transactional Model, this study aimed at analyzing factors that may safeguard partners and their relationship from detrimental effects of internal stress (i.e., stress that originates inside the relationship). We examined the buffering effect of partners' positive dyadic coping and internal problem resolution. Daily diary data were collected across 7 days from 82 heterosexual couples. Multilevel dyadic analyses showed that internal stress was negatively associated with partners' individual and relational well-being. Positive dyadic coping moderated the association between partners' internal stress and couple satisfaction for both partners, but not life satisfaction and couple identity. Moreover, for partners who reported a resolution to the internal problem, the negative associations of internal stress with life satisfaction, couple satisfaction, and couple identity were significantly lower than for those who did not resolve the internal problem. This study confirms the negative role of internal stress on well-being, shows the associations between internal stress and couple identity, and highlights the protective role of dyadic coping and internal problem resolution in couples' daily lives.     

Dementia with Lewy bodies: a pure case

A pure case of autopsy-confirmed dementia with Lewy bodies (DLB) is described. The patient presented with distinctive verbal fluency deficits in the context of mild language impairment, intact recognition memory, and impaired paragraph recall. Neuroimaging (CT and SPECT) showed progressive medial temporal lobe atrophy. Neuropathology revealed Lewy bodies, degeneration in the substantia nigra, nucleus basalis of Meynert (Nakano & Hirano, 1984), and locus ceruleus, but no pathology characteristic of Alzheimer's disease. It is in this sense that the case is "pure" DLB. Early neuropsychological diagnosis of DLB is essential (Salmon et al., 1996) given the potentially fatal hazard of neuroleptics (McKeith et al., 1992) and the difficulties associated with clinical neurological diagnoses (Litvan et al., 1998).     

Development and validation of the Moral Outcomes of Relationship Aggression Scale: A measure of moral distress following intimate partner violence perpetration

Research with military veterans has established that distress may arise in response to perpetrating violent behaviors that violate individuals' moral beliefs. To date, no studies have similarly examined morally-related cognitive and emotional responses specifically among intimate partner violence (IPV) perpetrators. However, research on moral cognitions and emotions in response to IPV perpetration may inform understanding of the behavior and potential mechanisms for intervention. In the current series of four studies, we used classical test theory to develop a measure of moral distress following IPV perpetration that focuses on thoughts about the actions (assimilated cognitions), thoughts about the self due to one's actions (accommodated cognitions), and emotions experienced due to one's actions (moral emotions). Items were developed and tested among two samples of undergraduate students, and psychometric properties of the final measure were confirmed among two community samples. The final measure consists of three subscales consisting of five items each. Results demonstrate support for internal consistency and test–retest reliability, convergent, discriminant, and incremental validity, and factor structure. This measure can be used in future research designed to examine how individuals respond to their IPV perpetration, and to study the implications this may have for long-term outcomes and behavioral change.     

The Silent Majority: Understanding and Increasing Majority Group Responses to Discrimination

Although strong norms exist against discrimination, majority group members are surprisingly unlikely to respond assertively to discrimination when they witness it. A number of factors contribute to majority group members' nonresponse, including lack of intergroup contact, motivation not to see discrimination, unsupportive social norms, and the sense that only members of affected groups are entitled to respond to discrimination. This paper reviews the published evidence supporting this pattern and presents a model of targeted social referencing, whereby majority group members look to, and are uniquely influenced by, the opinions of minority group members in the domain of discrimination. This article reviews the causes and implications of targeted social referencing and proposes interventions aimed at increasing majority group responses to discrimination.
