Navigating the landscape of fear: Fruit flies exhibit distinct antipredator and antiparasite defensive behaviors.

Most organisms are at risk of being consumed by a predator or getting infected by a parasite at some point in their life. Theoretical constructs such as the landscape of fear (perception of risk) and nonconsumptive effects (NCEs, costly responses sans predation or infection) have been proposed to describe and quantify antipredator and antiparasite responses. How prey/host species identify and respond to these risks determines their survival, reproductive success and, ultimately, fitness.

The role of acute stress recovery in emotional resilience.

Background: Resilience refers to the process of demonstrating better outcomes than would be expected based on the adversity one experienced. Resilience is increasingly measured using a residual approach, which typically assesses adversity and mental health outcomes over a longitudinal timeframe. It remains unknown to what extent such a residual-based measurement of resilience is sensitive to variation in acute stress resilience, a candidate resilience factor.

Severe measles with pneumonitis in an immunocompetent adult.

Measles is a highly contagious but vaccine-preventable airborne-transmitted viral infection of which there has been a recent resurgence of cases worldwide over the past year, including in countries such as the UK, which had previously successfully achieved endemic measles elimination through vaccination programmes. Measles is typically a self-limiting illness, but can rarely cause severe, life-threatening disease, particularly when complicated by respiratory or neurological involvement. These severe complications are not typically seen in the absence of immunosuppression.

How varying cue duration influences item-method directed forgetting: A novel selective retrieval interpretation.

A series of four experiments tested the assumptions of the most prominent and longstanding account of item-method directed forgetting: the selective rehearsal account. In the item-method directed forgetting paradigm, each presented item is followed by its own instructional cue during the study phase - either to-be-forgotten (F) or to-be-remembered (R). On a subsequent test, memory is poorer for F items than for R items.

Towards implementation of cognitive bias modification in mental health care: State of the science, best practices, and ways forward.

Cognitive bias modification (CBM) has evolved from an experimental method testing cognitive mechanisms of psychopathology to a promising tool for accessible digital mental health care. While we are still discovering the conditions under which clinically relevant effects occur, the dire need for accessible, effective, and low-cost mental health tools underscores the need for implementation where such tools are available. Providing our expert opinion as Association for Cognitive Bias Modification members, we first discuss the readiness of different CBM approaches for clinical implementation, then discuss key considerations with regard to implementation.

The role of expectancies and selective interrogation of information in trait anxiety-linked affect when approaching potentially stressful future events.

The present study examined cognitive mechanisms underpinning the increased tendency of individuals with high trait anxiety to experience inflation of negative affect when approaching potential stressors. Specifically, the roles of (1) disproportionately negative relative to positive expectancies (i.e.

The effect of a pilot brief educational intervention on preferences regarding treatments for opioid use disorder.

Purpose: Negative perceptions around medications for opioid use disorder (MOUD) amongst the public could deter patients with opioid use disorder (OUD) from engaging with MOUD. Thus, we evaluated whether a brief intervention could improve preferences for MOUD in people who may or may not use opioids.

Methods: We employed a pre-post design to assess the effect of a brief educational intervention on preferences for methadone, buprenorphine, naltrexone, and non-medication treatment in an online sample of US adults stratified by race, who may or may not use opioids.

Perceptions around medications for opioid use disorder among a diverse sample of U.S. adults.

Introduction: Medications for opioid use disorder (MOUD) including methadone (MMT), buprenorphine (BUP), and naltrexone (NTX) are safe and effective. However, there are significant negative perceptions surrounding MOUD, creating barriers to uptake. While research on MOUD stigma has largely focused on provider and patient experiences, fewer studies have explored MOUD perceptions among the general public.

On the association between intention and visual word identification.

One of the most fundamental distinctions in cognitive psychology is between processing that is "controlled" and processing that is "automatic." The widely held automatic processing account of visual word identification asserts that, among other characteristics, the presentation of a well-formed letter string triggers sublexical, lexical, and semantic activation in the absence of any intention to do so. Instead, the role of intention is seen as independent of stimulus identification and as restricted to selection for action using the products of identification (e.

Less bang for my buck: Diminished anticipated enjoyment contributes to dysphoria-linked deficit in activity behavioural engagement choice.

This study experimentally investigated the role of anticipated enjoyment and effort in mediating dysphoria-related deficit in activity engagement behavioural choice. Using a novel activity information processing task (about a fictional "new" Nintendo Wii sports game called "Tornado Ball"), N = 249 participants (n = 95 High Dysphoria; n = 154 Low Dysphoria) were presented information about the benefits (enjoyable features) and costs (mental and physical effort barriers) as product reviews from another player. The order of cost vs.

IMproving psYchosocial adjustment to Traumatic Brain Injury from acute to chronic injury through development and evaluation of the online psychoeducation platform: protocol for a mixed-methods study.

Introduction: This protocol describes the study which aims to: (1) develop an online psychoeducation platform for people with traumatic brain injury (TBI), their family members/caregivers, and healthcare staff to improve psychosocial adjustment to TBI across different phases of injury (acute, postacute, and chronic), and (2) undertake an evaluation of efficacy, acceptability, and feasibility.

Methods And Analysis: A three-stage mixed-methods research design will be used. The study will be undertaken across four postacute community-based neurorehabilitation and disability support services in Western Australia.

Productions Need Not Match Study Items to Confer a Production Advantage, But It Helps.

The production effect is the finding that, relative to silent reading, producing information at study (e.g., reading aloud) leads to a benefit in memory.

Improving Medical Student Knowledge and Reducing Stigmatizing Attitudes Toward Treating Patients With Opioid Use Disorder.

Objectives: Stigma and lack of knowledge are barriers to clinicians when caring for individuals with opioid use disorder (OUD). In 2018, only about 15 out of 180 American medical schools had comprehensive addiction programs. The AAMC reports that institutions are increasingly incorporating competencies to address the OUD and opioid epidemic.

Release from response interference in color-word contingency learning.

In identifying the print colors of words when some combinations of color and word occur more frequently than others, people quickly show evidence of learning these associations. This contingency learning effect is evident in faster and more accurate responses to high-contingency combinations than to low-contingency combinations. Across four experiments, we systematically varied the number of response-irrelevant word stimuli connected to response-relevant colors.

Attentional engagement with and disengagement from appearance ideals: Differential associations with body dissatisfaction frequency and duration?

Recent work has served to dissociate two dimensions of trait body dissatisfaction: body dissatisfaction frequency and body dissatisfaction duration. The present study sought to evaluate whether body dissatisfaction frequency and body dissatisfaction duration are each associated with distinct patterns of appearance-related cognitive processing. It was hypothesized that speeded attentional engagement with idealized bodies is associated with higher frequency of body dissatisfaction episodes, while slowed attentional disengagement from such information may instead be associated with higher duration of body dissatisfaction episodes.

The legacy of social anxiety-linked negative expectancy: A pathway from pre-event negative expectancies to post-event negative thinking.

Background And Objectives: Following engagement in a social event people with heightened vulnerability to social anxiety report elevated levels of negative thinking about the event, and this post-event negative thinking is implicated in the maintenance of social anxiety vulnerability. It has also been established that heightened social anxiety vulnerability is associated with disproportionately negative expectations of upcoming social events. However, contribution of social anxiety-linked pre-event negative expectancy to post-event negative thinking has not been directly investigated.

Tropical Data: Approach and Methodology as Applied to Trachoma Prevalence Surveys.

Purpose: Population-based prevalence surveys are essential for decision-making on interventions to achieve trachoma elimination as a public health problem. This paper outlines the methodologies of Tropical Data, which supports work to undertake those surveys.

Methods: Tropical Data is a consortium of partners that supports health ministries worldwide to conduct globally standardised prevalence surveys that conform to World Health Organization recommendations.

The impact of self-referential processing on depression-linked negative interpretive bias.

Background And Objectives: Cognitive theories propose that individuals with heightened depression are characterized by biases in memory and interpretation, favoring the processing of negative information. Individuals with heightened depression exhibit a negative memory bias, and this bias is disproportionately evident when emotional information is processed in a self-referential manner. In studies investigating whether individuals with heightened depression exhibit a negative interpretative bias, the measures employed have often been compromised by serious methodological limitations.

The prod eff: Partially producing items moderates the production effect.

Current accounts of the production effect suggest that production leads to the encoding of additional production-associated features and/or better feature encoding. Thus, if it is the act of production that leads to the storage and/or enhanced encoding of these features, then less of this act should reduce the resulting production effect. In two experiments, we provide a direct test of this idea by manipulating how much of a given item is produced within a single mode of production (typing).

Examining the role of trait anxiety and attentional bias to negative information in intrusion vulnerability following an emotionally negative event.

Background And Objectives: Research shows that individuals with heightened trait anxiety are more likely to experience intrusions; however, the mechanism that accounts for this relationship is unclear. Two alternative hypotheses were tested to determine the nature of the associations between trait anxiety, attentional bias to negative information, and intrusion vulnerability.

Methods: Intrusions were elicited using the trauma film paradigm, and post-event attentional bias to negative information was assessed using the dot-probe task.

Reading text aloud benefits memory but not comprehension.

The production effect-that reading aloud leads to better memory than does reading silently-has been defined narrowly with reference to memory; it has been explored largely using word lists as the material to be read and remembered. But might the benefit of production extend beyond memory and beyond individual words? In a series of four experiments, passages from reading comprehension tests served as the study material. Participants read some passages aloud and others silently.

Serotonin and emotion regulation: the impact of tryptophan depletion on emotional experience, neural and autonomic activity.

The involvement of serotonin in emotion and psychopathology has been extensively examined. Studies using acute tryptophan depletion (ATD) have found limited effects on mood and aggression, and one of the explanations suggests that serotonin may be involved in higher-order functions, such as emotion regulation. However, there is very limited evidence for this hypothesis.

Investigating the role of action-contingent expectancy biases in dysphoria-linked activity engagement behavioural choice.

Reduced tendency to engage in potentially rewarding activities is a hallmark of depression. The present study investigated the role of future expectancy biases in depression-linked behavioural choice, in participants varying in self-reported depression symptoms (dysphoria). A novel laboratory paradigm was developed to test the hypotheses that the degree to which higher dysphoria is associated with reduced tendency to engage in a potentially rewarding activity is dependent on the presence of negative biases in the expected outcomes of activity engagement.
