Stereotype Threat and OC Symptomatology: The Impact of Messy vs. Clean Environments on Cognitive Test Performance

Stereotype threat has been researched in a variety of contexts such as African Americans’ intellect, older adults’ memory, and women’s performance in math. Despite this extensive research, little has been done in the domain of mental illness. This study examines whether stereotype threat can be induced in people high in obsessive compulsive (OC) symptoms. We hypothesized that, when given explicit information about their OC tendencies, individuals high in OC symptoms would perform less well on cognitive tests in a messy than a clean environment compared to those low in OC symptoms. Group testing sessions included a mix of college students high (n=25) and low (n=22) in OC symptomatology. The classroom and testing packets were either messy or clean. At the beginning of the session, participants were given confidential, accurate information about their OC tendencies before completing tests of concentration and immediate and delayed memory. Across the four tests, the High and Low OC groups performed similarly in a non-threat inducing clean environment. However, in a threat-inducing messy environment the High OC group showed a strong tendency to perform less well than the Low OC group on a test of auditory attention. Thus, our results suggest that individuals with OCD or related symptoms may be susceptible to stereotype threat, much like other vulnerable populations

The Role and Need for Space-Based Forest Biomass-Related Measurements in Environmental Management and Policy

The achievement of international goals and national commitments related to forest conservation and management, climate change, and sustainable development requires credible, accurate, and reliable monitoring of stocks and changes in forest biomass and carbon. Most prominently, the Paris Agreement on Climate Change and the United Nations’ Sustainable Development Goals in particular require data on biomass to monitor progress. Unprecedented opportunities to provide forest biomass data are created by a series of upcoming space-based missions, many of which provide open data targeted at large areas and better spatial resolution biomass monitoring than has previously been achieved. We assess various policy needs for biomass data and recommend a long-term collaborative effort among forest biomass data producers and users to meet these needs. A gap remains, however, between what can be achieved in the research domain and what is required to support policy making and meet reporting requirements. There is no single biomass dataset that serves all users in terms of definition and type of biomass measurement, geographic area, and uncertainty requirements, and whether there is need for the most recent up-to-date biomass estimate or a long-term biomass trend. The research and user communities should embrace the potential strength of the multitude of upcoming missions in combination to provide for these varying needs and to ensure continuity for long-term data provision which one-off research missions cannot provide. International coordination bodies such as Global Forest Observations Initiative (GFOI), Committee on Earth Observation Satellites (CEOS), and Global Observation of Forest Cover and Land Dynamics (GOFC‐GOLD) will be integral in addressing these issues in a way that fulfils these needs in a timely fashion. Further coordination work should particularly look into how space-based data can be better linked with field reference data sources such as forest plot networks, and there is also a need to ensure that reference data cover a range of forest types, management regimes, and disturbance regimes worldwide

Compared to What? The Effects of a Frame of Reference on Older Adults’ Subjective Memory

It is often unclear what comparisons older adults make when evaluating their own memory. If thinking about their memory relative to others, they may assess their own abilities differently than if comparing it to their past capabilities. To test the effect of reference frames on memory assessments and memory performance, we randomly assigned 120 older adults to one of three conditions in which we manipulated frames of reference (control, past-self comparison, or other adults comparison) on a memory self-efficacy questionnaire. Participants also completed general and specific memory predictions and an objective memory test. Participants in the past-self condition reported significantly lower global memory self-efficacy compared with the other adults and control conditions. No condition differences emerged for memory predictions, objective memory, or the likelihood of over- or underpredicting memory performance. These findings suggest that reference frames impact global memory self-efficacy, but do not influence the accuracy of subjective memory judgments
