Working memory and spatial judgments: Cognitive load increases the central tendency bias

Previous work demonstrates that memory for simple stimuli can be biased by information about the distribution of which the stimulus is a member. Specifically, people underestimate values greater than the distribution’s average and overestimate values smaller than the average. This is referred to as the central tendency bias. This bias has been explained as an optimal use of both noisy sensory information and category information. In largely separate literature, cognitive load (CL) experiments attempt to manipulate the available working memory of participants in order to observe the effect on choice or judgments. In two experiments, we demonstrate that participants under high cognitive load exhibit a stronger central tendency bias than when under a low cognitive load. Although not anticipated at the outset, we also find that judgments exhibit an anchoring bias not described previously.     

Further evaluation of latency measures in the assessment and treatment of severe self‐injurious behavior

Recent research has demonstrated the utility of latency measures during the functional analysis of problem behavior; however, few studies have evaluated the utility of latency measures during subsequent treatment analyses. The current study seeks to extend the literature on the use of latency measures during the treatment of severe self‐injurious behavior (SIB). Following a latency‐based functional analysis, a treatment analysis was conducted using a hybrid procedure in which baseline sessions were terminated following the first instance of SIB, and test sessions ended after a fixed length of time. Latency to SIB was compared across conditions, whereas latency and rate measures for both SIB and functional communication responses were compared for the functional communication training condition. Results suggest that latency measures may be too sensitive during treatment analyses and that it is beneficial to use a hybrid procedure that allows for both latency and rate comparisons.     

The Caregivers' Attachment and Relationship Education Class: A New and Promising Group Therapy for Caregivers of Individuals with Parkinson's Disease

The authors examined whether a newly developed group therapy, based on principles of attachment theory and emotionally focused couples therapy, can potentially address the unique mental health and relationship difficulties in caregivers of individuals with Parkinson's disease. A comprehensive outreach effort, involving a review of 251 military veterans' medical records, yielded enrollment of seven spousal caregivers in the group therapy. At 1-month follow-up, caregivers who initially reported mild or greater levels of caregiver burden demonstrated statistically reliable declines in psychological distress, relationship distress, or both. Posttreatment surveys indicated positive perceptions in overall helpfulness of treatment goals, as well as positive changes in insight (e.g., greater understanding of the patient's attachment needs) and behaviors (e.g., greater social contact and self-care of the caregiver). Results are considered in the context of inadequate access to treatment for caregivers of spouses with Parkinson's disease or other major medical issues.     

Stigma on my mind: Individual differences in the experience of stereotype threat

Stereotyped individuals vary in how chronically self-conscious they are of their stigmatized status, which Pinel (1999) has dubbed stigma consciousness. The current study investigated whether individual differences in stigma consciousness moderate the impact of gender stereotypes on the math performance of women. Results indicated that, under conditions designed to evoke stereotype threat (Steele, 1997), women high in stigma consciousness scored worse than women low in stigma consciousness on a math test. In the control (low threat) condition, stigma consciousness was unrelated to test performance. Possible mechanisms underlying this moderation are discussed.     

Cognitive testing of an instrument to evaluate acceptability and use of pre-exposure prophylaxis products among women

Given the range of pre-exposure prophylaxis (PrEP) products currently being tested to prevent HIV in women, a standardized Acceptability and Use of PrEP Products Among Women Tool may facilitate comparisons of product acceptability and use across different geographies, trials, and users. We conducted three rounds of cognitive interviewing over 2 months in 2016, with 28 South African women who had experience participating in a range of PrEP product trials. The final instrument contained 41 items, including five new items that improved construct validity and 22 items modified for clarity. Changes were made due to unclear wording, difficulty answering, participant embarrassment, low response variability, and administrative formatting. Cognitive interviewing provided a means to address issues that would have inhibited this tool's ability to accurately collect data otherwise. This rapid, low-cost study provided valuable insight into participants' understanding of questions and demonstrated the utility of cognitive interviewing in international clinical trials.     

Learning From Gesture and Action: An Investigation of Memory for Where Objects Went and How They Got There

Speakers often use gesture to demonstrate how to perform actions—for example, they might show how to open the top of a jar by making a twisting motion above the jar. Yet it is unclear whether listeners learn as much from seeing such gestures as they learn from seeing actions that physically change the position of objects (i.e., actually opening the jar). Here, we examined participants' implicit and explicit understanding about a series of movements that demonstrated how to move a set of objects. The movements were either shown with actions that physically relocated each object or with gestures that represented the relocation without touching the objects. Further, the end location that was indicated for each object covaried with whether the object was grasped with one or two hands. We found that memory for the end location of each object was better after seeing the physical relocation of the objects, that is, after seeing action, than after seeing gesture, regardless of whether speech was absent (Experiment 1) or present (Experiment 2). However, gesture and action built similar implicit understanding of how a particular handgrasp corresponded with a particular end location. Although gestures miss the benefit of showing the end state of objects that have been acted upon, the data show that gestures are as good as action in building knowledge of how to perform an action.     

Does the Bible Tell Me So? Weighing the Influence of Content versus Bias on Bible Interpretation Using Survey Experiments

Discussions of biblical interpretation often proceed under one of two assumptions. Readers’ interpretations are primarily formed (1) inductively, according to the Bible's objective content, or (2) through the lens of preformed ideologies and biases. We assessed the influence of these two factors using two survey experiments with undergraduates. In study 1 (N = 214), participants were randomly assigned one of two nearly identical translations of Ephesians 5:22-28 (a famous passage describing gendered marital submission), with the only difference being that one translation included verse 21 in which Christians are told to “submit to one another.” Participants did not perceive a different message about gendered submission between translations, nor were they more likely to interpret either as misogynistic. However, gender ideology and religious importance did predict interpretation. Study 2 (N = 217) essentially replicated study 1 (using different translations of Ephesians 5:21-28), but one version replaced all “subjection” language with “commitment” language. Participants were significantly more likely to perceive a complementarian message from the translation that referenced “subjection” and they were also more likely to perceive it as misogynistic. Again, gender ideology and religious characteristics predicted interpretation. Findings suggest bias shapes interpretation, but more extreme content modifications (e.g., removing/changing key terms) can also influence interpretation.
