Output buffer storage and the modality of recall

In two experiments, subjects were presented with two lists of visual items simultaneously, both of which were to be recalled. The order of recall of the lists was manipulated. In Experiment 1, subjects were required to recall one list by speaking it and the other by writing it down. Prior knowledge of the particular mode of output required for each list resulted in significantly higher levels of recall than in a condition in which the output mode for each list was not known until after presentation. This result suggests that there may be at least two modality-specific output buffers. Experiment 2 employed the same method of presentation, but spoken recall of both lists was required. In addition, the priority of the lists was manipulated, and articulatory suppression was required in half of the trials. There was an effect of priority and of recall order, together with an interaction between the two. In contrast to the results of FitzGerald and Broadbent (1985a), however, who carried out a similar experiment but with written recall, articulatory suppression significantly reduced the priority and recall order interaction. It is concluded that there is one form of output buffer storage for written or manual output and one for spoken output.     

Sluggish Cognitive Tempo Symptoms Contribute to Heterogeneity in Adult Attention-Deficit Hyperactivity Disorder

Attention-deficit hyperactivity disorder (ADHD) persists into adulthood in over 50% of cases, although its associated symptom profiles, comorbid problems, and neuropsychological deficits change substantially across development. Sluggish cognitive tempo (SCT) symptoms may contribute to associations between ADHD and comorbid problems and may partially explain the substantial heterogeneity observed in its correlates. 349 adults aged 18–38 years (M = 23.2, SD = 4.5, 54.7% male, 61.03% with ADHD) completed a multi-informant diagnostic procedure and a comprehensive neuropsychological battery. Adults with ADHD (n = 213) were retained for analyses. Latent class analyses (LCA) revealed three profiles of SCT symptoms among those with ADHD, which we classified as minimal, moderate, or severe SCT. Multiple analysis of covariance (MANCOVA) revealed significant differences among these profiles, which remained when controlling for persistence of ADHD symptoms and sex. In general, adults with ADHD combined with SCT symptoms (moderate and severe) had significantly more symptoms of anxiety, depression, and persistent inattention, and had more severe professional and relational impairment compared to ADHD adults without SCT. Compared to those with moderate or minimal SCT symptoms, the severe SCT group had the most symptoms of depression and internalizing disorders, and the most impairment in the domain of daily responsibility. No significant differences based on externalizing symptoms emerged when controlling for sex and persistence of inattention symptoms, suggesting the moderate and severe SCT groups do not simply reflect more symptoms. Moreover, follow-up mediation analyses revealed that SCT might at least partially explain the heterogeneity in ADHD. Findings have implications for refinement of etiological conceptualization, assessment methods, and intervention strategies.     

Trauma Exposure and Health: A Review of Outcomes and Pathways

A growing body of literature has established robust relations between trauma and a variety of adverse physical health outcomes. In both retrospective and prospective research, adults with a history of self-reported or court-substantiated maltreatment report significantly more health concerns than those without maltreatment histories, in both clinical and community samples, whether health problems are self-reported or physician-diagnosed. Two pathways by which poor health outcomes are theorized to occur include the biological pathway, which largely implicates severe stress and subsequent dysregulations in central stress-response systems as the underlying cause of health problems, and the behavioral pathway, which suggests that health risk behaviors are largely responsible for the relations between trauma and health. This article reviews the research evaluating the relations between various types of trauma, particularly physical and sexual abuse in childhood, and three such health outcomes: pain, gastrointestinal disorders, and cardiovascular disease. Evidence to support the biological and behavioral pathways is also reviewed.     

Health-related quality of life in patients with systemic lupus erythematosus and proliferative lupus nephritis

This study investigated the influence of two different treatments for a kidney inflammation (i.e. proliferative lupus nephritis) on health-related quality of life (HRQoL) in patients with the chronic auto-immune disease systemic lupus erythematosus (SLE). One treatment protocol, the National Institutes of Health (NIH) protocol, was characterized by a high dose of cyclophosphamide (CYC, an immunosuppressive drug), and the second treatment, the Euro-Lupus protocol, involved a low-dose CYC. Thirty-two SLE patients were included based on the received treatment for an episode of proliferative lupus nephritis, according to either the Euro-Lupus or the NIH protocol. The two groups were compared on HRQoL as measured by the SF-36 and the SLE Symptom Checklist (SSC). The Euro-Lupus group (N?=?16) tended to show a higher HRQoL than the NIH group (N?=?16) on four of seven scales of the SF-36. In addition, the Euro-Lupus group experienced less burden from nausea or vomiting than the NIH group as assessed by the SSC. Fatigue was the most disturbing symptom in both groups. The most burdensome aspects of treatment were related to chemotherapy (55.2%) and use of prednisone (34.5%). Patients with a low HRQoL and high levels of fatigue were more likely to have low levels of serum complement C4 (i.e. elevated immune activity). In conclusion, patients who are treated according to the Euro-Lupus protocol may experience a higher HRQoL than patients who receive the NIH treatment. However, chemotherapy remains burdensome in the low-dose treatment regimen. Potential interventions to further enhance the HRQoL in SLE patients with proliferative lupus nephritis are discussed.     

A prospective study of pediatric loss of control eating and psychological outcomes

Loss of control (LOC) eating in youth is associated cross-sectionally with eating-related and psychosocial distress and is predictive of excessive weight gain. However, few longitudinal studies have examined the psychological impact and persistence of pediatric LOC eating. We administered the Eating Disorder Examination and self-reported measures of depressive and anxiety symptoms to 195 boys and girls (mean age = 10.4 years, SD = 1.5) at baseline and again 4.7 years (SD = 1.2) later to 118 of these youth. Missing data were imputed. Baseline report of LOC was associated with the development of partial- or full-syndrome binge eating disorder (p = .03), even after accounting for the contribution of sex, race, baseline characteristics (age, disordered eating attitudes, and mood symptoms), body mass index growth between baseline and follow-up, and years in study. Half (52.2%; 95% CI [1.15, 6.22]) of children who endorsed experiencing LOC at baseline reported persistence of LOC at follow-up (p = .02). Compared with children who never reported LOC eating or reported LOC only at baseline, those with persistent LOC experienced significantly greater increases in disordered eating attitudes (ps < .001) and depressive symptoms (p = .027) over time. These data suggest that LOC eating in children is a problematic behavior that frequently persists into adolescence and that persistent LOC eating is associated with worsening of emotional distress.     

Impaired visual and odor recognition memory span in patients with hippocampal lesions

In a recent study, rats with hippocampal lesions performed as well as did unoperated rats on an olfactory memory span task, performing ~80% correct even when the span length reached 24 odors. This finding seems potentially at odds with demonstrations that memory-impaired patients typically fail tasks in which large amounts of information must be retained. Accordingly, we have assessed recognition memory span performance for line drawings of objects, designs, and odors in amnesic patients with damage thought to be limited to the hippocampal region. The patients were impaired on all three tasks. We consider possible explanations for the difference between the findings for humans and rats, including the fact that olfactory function is particularly well-developed in rodents.

Incidental learning in a multisensory environment across childhood

Multisensory information has been shown to modulate attention in infants and facilitate learning in adults, by enhancing the amodal properties of a stimulus. However, it remains unclear whether this translates to learning in a multisensory environment across middle childhood, and particularly in the case of incidental learning. One hundred and eighty‐one children aged between 6 and 10 years participated in this study using a novel Multisensory Attention Learning Task (MALT). Participants were asked to respond to the presence of a target stimulus whilst ignoring distractors. Correct target selection resulted in the movement of the target exemplar to either the upper left or right screen quadrant, according to category membership. Category membership was defined either by visual‐only, auditory‐only or multisensory information. As early as 6 years of age, children demonstrated greater performance on the incidental categorization task following exposure to multisensory audiovisual cues compared to unisensory information. These findings provide important insight into the use of multisensory information in learning, and particularly on incidental category learning. Implications for the deployment of multisensory learning tasks within education across development will be discussed.     

Perpetrators’ reactions to perceived interpersonal wrongdoing: The associations of guilt and shame with forgiving,punishing, and excusing oneself

We describe a model in which guilt and shame associate with reactions to wrongdoing among perpetrators of interpersonal harm. Individuals who reported wronging another person (N = 410) completed measures of perceived transgression severity, guilt and shame, and possible reactions to perpetration of wrongdoing (i.e., forgiving, punishing, and excusing oneself). Guilt positively predicted forgiving and punishing oneself, and negatively predicted excusing oneself of blame. Shame, in contrast, negatively predicted forgiving oneself and positively predicted punishing and excusing oneself. The observed patterns of associations between guilt and shame with perpetrators’ reactions to wrongdoing provide further support for the dual-process model of self-forgiveness. Implications for future basic and applied investigations are discussed.     

Feminism: What is it Good For? Feminine Norms and Objectification as the Link between Feminist Identity and Clinically Relevant Outcomes

The goal of this study was to explore the relationships between feminism and clinical outcomes, such as eating attitudes, depression, and self-esteem, employing structural equation modeling to look at indirect relationships. This study examined female participants’ (N = 282) responses to an online survey measuring feminist self-identification, conformity to feminine norms, objectified body consciousness, eating attitudes, depression, and self-esteem. Participants were recruited on two college campuses and through online listservs. Feminist self-identification was related to rejecting the feminine norms of thinness, appearance, and the importance of romantic relationships. Endorsing these norms was related to increased body surveillance and shame. Objectification variables were related to negative clinical outcomes. Thus, feminism is a distal, rather than proximal, influence on clinical variables.
