Prospective cognitions in anxiety and depression: Replication and methodological extension

The present study presents a replication and methodological extension of MacLeod, Tata, Kentish, and Jacobsen (1997) with a nonclinical sample, using future-directed imagery to assess prospective cognitions. Results showed that only anxiety (but not depression) was related to enhanced imagery for future negative events. Both anxiety and depression showed significant zero-order correlations with reduced imagery for future positive events. However, when the overlap between anxiety and depression was controlled for, only depression (but not anxiety) showed a unique association with reduced imagery for positive events. Implications of these findings for cognitive models of anxiety and depression are discussed

Lessons from Europe for the study of international central bank cooperation

Cooperation between central banks has been crucial for stabilising the international financial system during the Global Financial Crisis in 2008 and the COVID-19 crisis in 2020. For students of international political economy, understanding why and how central banks cooperate is thus a highly relevant concern. This doctoral dissertation studies central bank cooperation in Europe during and after the Global Financial Crisis. It is based on 25 elite interviews, original archival material and other primary and secondary sources. It reconstructs how central banks came to the decision to conclude credit lines with one another, engaged in Balance-of-Payments assistance programmes, and built new regional institutions to coordinate crisis management and macroprudential policy measures. It finds that central banks motivated their decisions to cooperate not merely on the expected consequences of their actions, but also on their perceptions of appropriateness. Bilateral cooperation was often motivated by norms, such as solidarity, rather than being based predominantly on self-interest; regional financial governance takes the form of inclusive deliberations and consensus-building, rather than clashing national interests. These findings support the conclusions that central banks’ agency, and the ideas that guide their behaviour, need to be better understood to grasp the dynamics of international monetary cooperation.

International burden‑sharing during a financial crisis: We will all go together when we go

During the financial crisis of 2008–2010, governments have had varying success in containing the fiscal costs of stabilizing their financial sectors. This article challenges the existing literature that attributes these differences purely to national factors and contends that the international dimension affects a government’s capacity to share the costs across borders. Specifically, if a country shares a leveraged creditor with other countries, concerns about regional contagion will drive decisions by outside actors to participate in or prevent external burden sharing. A comparison of the role of the Swedish government during the financial crisis in Latvia and the ECB’s influence on Ireland shows that these decisions can both facilitate or prevent international burden-sharing. While Latvia benefited both from maintained exposure by Swedish banks and an internationally coordinated response to its crisis, the Irish government accumulated losses because foreign banks reduced their exposure and the European Central Bank vetoed “bailing in” bondholders of bankrupt banks. Future research on financial stabilization should therefore more explicitly consider possible contagion effects from bailing in foreign creditors.Institutions, Decisions and Collective Behaviou

The politicisation of the European Central Bank and its emergency credit lines outside the Euro Area

Is the European Central Bank (ECB) increasingly acting on political – rather than technocratic – considerations? This question is of a central concern to students of European Union (EU) political economy. This article contributes to this debate by studying the ECB’s credit lines to the central banks of EU member states outside the Euro Area during the Global Financial Crisis and the COVID-19 crisis. Both times the ECB accorded selectively better borrowing conditions to some central banks. The article finds that its selection of who gets favourable borrowing terms has indeed become more political. In 2008, the ECB decided the credit terms based on technocratic criteria, but twelve years later, it granted better lending conditions to countries that were close to adopting the euro. How the ECB balances its mandate for price stability in the Euro Area and its role as a supranational EU institution decides whether it will become more politicised.Institutions, Decisions and Collective Behaviou

Pylons ablaze: Examining the role of 5G COVID-19 conspiracy beliefs and support for violence

Amid increased acts of violence against telecommunication engineers and property, this pre‐registered study (N = 601 Britons) investigated the association between beliefs in 5G COVID‐19 conspiracy theories and the justification and willingness to use violence. Findings revealed that belief in 5G COVID‐19 conspiracy theories was positively correlated with state anger, which in turn, was associated with a greater justification of real‐life and hypothetical violence in response to an alleged link between 5G mobile technology and COVID‐19, alongside a greater intent to engage in similar behaviours in the future. Moreover, these associations were strongest for those highest in paranoia. Furthermore, we show that these patterns are not specific to 5G conspiratorial beliefs: General conspiracy mentality was positively associated with justification and willingness for general violence, an effect mediated by heightened state anger, especially for those most paranoid in the case of justification of violence. Such research provides novel evidence on why and when conspiracy beliefs may justify the use of violence

Glucose enhancement of memory is modulated by trait anxiety in healthy adolescent males

Glucose administration is associated with memory enhancement in healthy young individuals under conditions of divided attention at encoding. While the specific neurocognitive mechanisms underlying this ‘glucose memory facilitation effect’ are currently uncertain, it is thought that individual differences in glucoregulatory efficiency may alter an individual’s sensitivity to the glucose memory facilitation effect. In the present study, we sought to investigate whether basal hypothalamic–pituitary–adrenal axis function (itself a modulator of glucoregulatory efficiency), baseline self-reported stress and trait anxiety influence the glucose memory facilitation effect. Adolescent males (age range = 14–17 years) were administered glucose and placebo prior to completing a verbal episodic memory task on two separate testing days in a counter-balanced, within-subjects design. Glucose ingestion improved verbal episodic memory performance when memory recall was tested (i) within an hour of glucose ingestion and encoding, and (ii) one week subsequent to glucose ingestion and encoding. Basal hypothalamic–pituitary–adrenal axis function did not appear to influence the glucose memory facilitation effect; however, glucose ingestion only improved memory in participants reporting relatively higher trait anxiety. These findings suggest that the glucose memory facilitation effect may be mediated by biological mechanisms associated with trait anxiety

The Genesis 12–19 (G1219) Study: A Twin and Sibling Study of Gene–Environment Interplay and Adolescent Development in the UK

The Genesis 12–19 (G1219) Study is an ongoing longitudinal study of a sample of UK twin pairs, non-twin sibling pairs, and their parents. G1219 was initially designed to examine the role of gene–environment interplay in adolescent depression. However, since then data have continued to be collected from both parents and their offspring into young adulthood. This has allowed for longitudinal analyses of depression and has enabled researchers to investigate multiple phenotypes and to ask questions about intermediate mechanisms. The study has primarily focused on emotional development, particularly depression and anxiety, which have been assessed at multiple levels of analysis (symptoms, cognitions, and relevant environmental experiences). G1219 has also included assessment of a broader range of psychological phenotypes ranging from antisocial behaviors and substance use to sleep difficulties, in addition to multiple aspects of the environment. DNA has also been collected. The first wave of data collection began in the year 1999 and the fifth wave of data collection will be complete before the end of 2012. In this article, we describe the sample, data collection, and measures used. We also summarize some of the key findings to date

Altered hippocampal function in major depression despite intact structure and resting perfusion

Background: Hippocampal volume reductions in major depression have been frequently reported. However, evidence for functional abnormalities in the same region in depression has been less clear. We investigated hippocampal function in depression using functional magnetic resonance imaging (fMRI) and neuropsychological tasks tapping spatial memory function, with complementing measures of hippocampal volume and resting blood flow to aid interpretation. Method: A total of 20 patients with major depressive disorder (MDD) and a matched group of 20 healthy individuals participated. Participants underwent multimodal magnetic resonance imaging (MRI): fMRI during a spatial memory task, and structural MRI and resting blood flow measurements of the hippocampal region using arterial spin labelling. An offline battery of neuropsychological tests, including several measures of spatial memory, was also completed. Results: The fMRI analysis showed significant group differences in bilateral anterior regions of the hippocampus. While control participants showed task-dependent differences in blood oxygen level-dependent (BOLD) signal, depressed patients did not. No group differences were detected with regard to hippocampal volume or resting blood flow. Patients showed reduced performance in several offline neuropsychological measures. All group differences were independent of differences in hippocampal volume and hippocampal blood flow. Conclusions: Functional abnormalities of the hippocampus can be observed in patients with MDD even when the volume and resting perfusion in the same region appear normal. This suggests that changes in hippocampal function can be observed independently of structural abnormalities of the hippocampus in depression

Consumption of cocoa flavanols results in acute improvements in mood and cognitive performance during sustained mental effort

Cocoa flavanols (CF) positively influence physiological processes in ways that suggest their consumption may improve aspects of cognitive function. This study investigated the acute cognitive and subjective effects of CF consumption during sustained mental demand. In this randomized, controlled, double-blinded, balanced, three period crossover trial 30 healthy adults consumed drinks containing 520 mg, 994 mg CF and a matched control, with a three-day washout between drinks. Assessments included the state anxiety inventory and repeated 10-min cycles of a Cognitive Demand Battery comprising of two serial subtraction tasks (Serial Threes and Serial Sevens), a Rapid Visual Information Processing (RVIP) task and a mental fatigue scale, over the course of 1 h. Consumption of both 520 mg and 994 mg CF significantly improved Serial Threes performance. The 994 mg CF beverage significantly speeded RVIP responses but also resulted in more errors during Serial Sevens. Increases in self-reported mental fatigue were significantly attenuated by the consumption of the 520 mg CF beverage only. This is the first report of acute cognitive improvements following CF consumption in healthy adults. While the mechanisms underlying the effects are unknown they may be related to known effects of CF on endothelial function and blood flow

Attentional bias towards threatening and neutral facial expressions in high trait anxious children.

Research suggests anxious children display increased attentional biases for threat-related stimuli. However, findings based upon spatial domain research are equivocal. Moreover, few studies allow for the independent analysis of trials containing neutral (i.e., potentially ambiguous) faces. Here, we report two temporal attentional blink experiments with high trait anxious (HTA) and low trait anxious (LTA) children. In an emotive experiment, we manipulated the valence of the second target (T2: threatening/positive/neutral). Results revealed that HTA, relative to LTA, children demonstrated better performance on neutral trials. Additionally, HTA children demonstrated a threat-superiority effect whereas LTA children demonstrated an emotion-superiority effect. In a non-emotive control, no differences between HTA and LTA children were observed. Results suggest trait anxiety is associated with an attentional bias for threat in children. Additionally, the neutral face finding suggests HTA children bias attention towards ambiguity. These findings could have important implications for current anxiety disorder research and treatments
