The effects of co‐occurring ADHD symptoms on electrophysiological correlates of cognitive control in young people with Tourette syndrome

Efficient cognitive control is implicated in tic control in young people with Tourette syndrome (TS). Attention‐deficit/hyperactivity disorder (ADHD) frequently co‐occurs with TS and is associated with impaired cognitive control. Young people with TS and ADHD (TS+ADHD) show poorer cognitive control performance than those with TS, but how co‐occurring ADHD affects underlying neural activity is unknown. We investigated this issue by examining behavioural and event‐related potential (ERP) correlates of cognitive control in young people with these conditions. Participants aged 9–17 with TS (n = 17), TS+ADHD (n = 17), ADHD (n = 11), and unaffected controls (n = 20) performed a visual Go/Nogo task during electroencephalography (EEG) recording. Behavioural performance measures (D‐prime, RT, reaction time variability, post‐error slowing) and ERP measures (N2, P3, error‐related negativity (ERN), error positivity (Pe)) were analysed in a 2 (TS‐yes, TS‐no) × 2 (ADHD‐yes, ADHD‐no) factorial analysis to investigate the effects of TS, ADHD, and their interaction. The results of these analyses showed that ADHD was associated with poorer performance and reduced amplitude of all ERPs, reflecting widespread cognitive control impairments. Tourette syndrome was associated with slowed RTs, which might reflect a compensatory slowing of motor output to facilitate tic control. There was no interaction between the TS and ADHD factors for any behavioural or ERP measure, indicating the impairing effects of ADHD on behaviour and electrophysiological markers of cognitive control were present in TS+ADHD and that RT slowing associated with TS was unaffected by co‐occurring ADHD symptoms.     

Implicit sequence learning in young people with Tourette syndrome with and without co-occurring attention-deficit/hyperactivity disorder

Impaired habit-learning has been proposed to underlie the tic symptoms of Tourette syndrome (TS). However, accounts differ in terms of how habit-learning is altered in TS, with some authors proposing habit formation is impaired due to a deficient ‘chunking’ mechanism, and others proposing habit-learning is overactive and tics reflect hyperlearned behaviours. Attention-deficit/hyperactivity disorder (ADHD) frequently co-occurs with TS and is known to affect cognitive function in young people with co-occurring TS and ADHD (TS + ADHD). It is unclear, however, how co-occurring ADHD symptoms affect habit-learning in TS. In this study, we investigated whether young people with TS would show deficient or hyperactive habit-learning, and assessed the effects of co-occurring ADHD symptoms on habit-learning in TS. Participants aged 9–17 years with TS (n = 18), TS + ADHD (n = 17), ADHD (n = 13), and typical development (n = 20) completed a motor sequence learning task to assess habit-learning. We used a 2 (TS-yes, TS-no) × 2 (ADHD-yes, ADHD-no) factorial analysis to test the effects of TS, ADHD, and their interaction on accuracy and reaction time indices of sequence learning. TS was associated with intact sequence learning, but a tendency for difficulty transitioning from sequenced to non-sequenced performance was suggestive of hyper-learning. ADHD was associated with significantly poorer accuracy during acquisition of the sequence, indicative of impaired habit-learning. There were no interactions between the TS and ADHD factors, indicating young people with TS + ADHD showed both TS- and ADHD-related atypicalities in habit-learning.     

Finding Motivation to Learn: Exploring Achievement Goals in California Community College CalWORKs Students

This study investigated the achievement goals and motivations of California Community College CalWORKs students in an effort to better support student success and persistence. This study was guided by three research questions: (1) What type of achievement goals do CalWORKs students enter with? (2) What are their rationales for these types of achievement goals? (3) How malleable are these achievement goals? Interviews with 48 participants focused on better understanding the relationship between achievement goal type and motivation changes while in college. Findings indicate that CalWORKs students enter college with a range of goal types, but formany changes in goal type led to more intrinsic motivation and ultimately persistence toward graduation and career goals. Findings from this study also reveal thatexperiences highlighting students' ability to be competent as learners while balancing other roles helped catalyze change in achievement goal type and/or rationale. The results of this study emphasize that CalWORKs students' achievement goals are malleable, and particular college experiences can facilitate students' movement toward more academically focused goals. More specifically, placing more focus on additional student support programs that can foster peer networking, faculty interactions, and additional career exploration opportunities can lead to change in academic persistence.     

Metacognition during unfamiliar face matching

Kruger and Dunning (1999) described a metacognitive bias in which insight into performance is linked to competence: poorer performers are less aware of their mistakes than better performers. Competence-based insight has been argued to apply generally across task domains, including a recent report investigating social cognition using a variety of face-matching tasks. Problematically, serious statistical and methodological criticisms have been directed against the traditional method of analysis used by researchers in this field. Here, we further illustrate these issues and investigate new sources of insight within unfamiliar face matching. Over two experiments (total N = 1077), where Experiment 2 was a preregistered replication of the key findings from Experiment 1, we found that insight into performance was multi-faceted. Participants demonstrated insight which was not based on competence, in the form of accurate updating of estimated performance. We also found evidence of insight which was based on competence: the difference in confidence on correct versus incorrect trials increased with competence. By providing ways that we can move beyond problematic, traditional approaches, we have begun to reveal a more realistic story regarding the nature of insight into face perception.     

Aggression as One Response to Conflict1

This paper presents two studies that explore the link between self-reported conflict management strategies and aggression. It was predicted that conflict strategies involving concern for the needs of the other would be inconsistent with aggressive behavior. On the other hand, conflict strategies that involve coercion and domination were predicted to be positively related to aggressive behavior. Studies using self-report and behavioral measures of aggression provide support for these predictions.     

Therapeutic approaches to inhibited sexual desire in lesbians

Traditional approaches to inhibited sexual hire (ISD)—which may be exclusively heterosexist, erotophobic, sexist, and homophobic—fail to adequately address ISD within the lesbian population, in which incest and substance abuse occur commonly. Successful treatment of ISD among lesbians requires awareness of sexual minority customs, lesbian psychologies, and recovery agendas.     

Floating Provisos and Sinking Islands

Rising sea levels may sink entire countries. Individualistic solutions to this climate catastrophe, such as those proposed by Meisels and Risse, are inadequate on both Kantian and Lockean criteria. This article concurs with Cara Nine's recent argument that such ‘ecological refugee states’ are entitled to territorial remedies. But Nine's proposal, founded on Locke's ‘sufficiency’ proviso and Nozick's famous application of it to waterholes in the desert, is instructively incorrect. Careful consideration of the distinction between land and territory, and of the structure of Proviso arguments, supports a new theory of how territorial claims can be positive‐sum — how the amount of territory can increase even as the land base remains constant or decreases. This normative conception of territory as the ratio of justice to land use provides a better foundation for a political solution to the problem of ecological refugee states and also generates deeper insight into the nature of territory itself. The article thus contributes not only to our thinking about redress for ecological refugees, but also to the burgeoning literatures on territory and on the Lockean Provisos.     

University Support for Student Volunteering in England: Historical Development and Contemporary Value

This article draws on a major study of student volunteering based on case studies of six Higher Education Institutions (HEIs) selected to represent the diversity of the higher education sector in England. The study finds that students contribute significantly to university life and to the wider community through both formal and informal volunteering. However in this paper we consider the challenges and problems with the organisation of student volunteering. Our research finds that students who were supported by their university to volunteer reported better experiences of volunteering and identified greater impacts on their personal development, soft skills, employability and community awareness. In this paper we challenge the tendency of some policy makers and practitioners to view student volunteering as an automatic ‘win, win, win’—for students, for universities and for communities. Rather we explore how without adequate support, management and opportunities for reflection and placing volunteering in wider social context, student volunteering can fail to benefit any of these groups. The paper outlines the development of institutional support for volunteering by students before assessing the value such support has for student volunteers today.
