Clinical Use of the Surgeon General’s “My Family Health Portrait” (MFHP) Tool: Opinions of Future Health Care Providers

This study examined medical students’ and house officers’ opinions about the Surgeon General’s “My Family Health Portrait” (MFHP) tool. Participants used the tool and were surveyed about tool mechanics, potential clinical uses, and barriers. None of the 97 participants had previously used this tool. The average time to enter a family history was 15 min (range 3 to 45 min). Participants agreed or strongly agreed that the MFHP tool is understandable (98%), easy to use (93%), and suitable for general public use (84%). Sixty-seven percent would encourage their patients to use the tool; 39% would ensure staff assistance. Participants would use the tool to identify patients at increased risk for disease (86%), record family history in the medical chart (84%), recommend preventive health behaviors (80%), and refer to genetics services (72%). Concerns about use of the tool included patient access, information accuracy, technical challenges, and the need for physician education on interpreting family history information.     

Low environmental calcium blocks long-term memory formation in a freshwater pulmonate snail

The freshwater snail Lymnaea stagnalis (L.) is considered a calciphile and exhibits reduced growth and survival in environments containing less than 20 mg/l environmental calcium. Although it has no apparent effect on survival at 20 mg/l, reducing environmental calcium increases metabolic demand, and as such we consider that this level of calcium acts as a stressor on the snail. We exposed snails to acute periods of low environmental calcium and tested their ability to form intermediate-term memory (ITM) and long-term memory (LTM) following one trial operant conditioning (1TT) to reduce aerial respiratory activity in hypoxic conditions. We also assessed whether there were changes in the electrophysiological properties of a single neuron, right pedal dorsal 1 (RPeD1), which has been demonstrated to be necessary for LTM formation. Following training in high (80 mg/l) environmental calcium, L. stagnalis formed ITM and LTM lasting 24 h and demonstrated a significant reduction in all activity measured from RPeD1; however when snails were exposed to low (20 mg/l) environmental calcium they were able to form ITM but not LTM. Although no behavioral LTM was formed, a partial reduction in RPeD1 activtiy measured 24 h after training was observed, indicating a residual effect of training. The strong effect that environmental calcium concentration had on physiology and behavior in response to training to reduce aerial respiration in L. stagnalis suggests that it is an element of gastropod husbandry that needs to be carefully considered when studying other traits. This study also indicates that L. stagnalis found naturally in low calcium environments may be less able to adapt to novel stressors than populations found in harder waters.     

Response repetition as an error‐correction procedure for sight‐word reading: A replication and extension

We evaluated the effects of response repetition (RR) as an error‐correction procedure for increasing sight‐word reading for four individuals using a multiple baseline design. The results for each participant showed that correct responding increased following the introduction of the RR procedure. In addition, responding for three of four participants showed evidence of stimulus generalization, response generalization, or both. Likewise, we found that comparable behavior changes were produced when a participant's paraprofessional implemented RR in a typical classroom. These findings are briefly discussed in terms of procedures that promote behavior acquisition and generalization via negative reinforcement. Copyright © 2010 John Wiley & Sons, Ltd.     

Motor and visual codes interact to facilitate visuospatial memory performance

The spatial working memory system constantly updates spatial representations and many studies have focused on the underlying principles of the encoding and maintenance of visual information. Here we investigated the question of how the production of actions influences spatial working memory. Participants were given a task that required concurrent maintenance of two spatial arrays, one encoded by visual observation accompanied with pointing movements, the other by only visual observation. Across two experiments, movement during encoding was found to facilitate recognition of spatial arrays in a load-dependent manner. The results suggest an action-based encoding principle within the working memory system, and possible underlying action-related mechanisms are discussed.     

Consumer decision making and aging: A commentary from a public policy/marketing perspective

Efforts to assist older adults with cognitive deficits can take one of three paths: law, education or marketing. Legal protections have proved insufficient. Government educational efforts are typically dryly factual and likely to go unheeded. With the growing size of the older adult market, the independent efforts of both for-profit and social marketers to develop products and services that can help this population remain functionally healthy and independent are likely to be successful. Both governments and insurance companies should be motivated to help subsidize these entrepreneurial efforts given the considerably higher costs of caring for the elderly in an institution.     

Concurrent working memory load can facilitate selective attention: evidence for specialized load

Load theory predicts that concurrent working memory load impairs selective attention and increases distractor interference (N. Lavie, A. Hirst, J. W. de Fockert, & E. Viding). Here, the authors present new evidence that the type of concurrent working memory load determines whether load impairs selective attention or not. Working memory load was paired with a same/different matching task that required focusing on targets while ignoring distractors. When working memory items shared the same limited-capacity processing mechanisms with targets in the matching task, distractor interference increased. However, when working memory items shared processing with distractors in the matching task, distractor interference decreased, facilitating target selection. A specialized load account is proposed to describe the dissociable effects of working memory load on selective processing depending on whether the load overlaps with targets or with distractors.     

MEMORY ALTERING TECHNOLOGIES AND THE CAPACITY TO FORGIVE: WESTWORLD AND VOLF IN DIALOGUE

I explore the impact of memory altering technologies in the science fiction drama (2016–2020) in order to show that unreconciled altered traumatic memory may lead to a dystopian breakdown of society. I bring Miroslav Volf's theological perspectives on memory into conversation with the plot of Westworld in order to reveal connections between memory altering technologies and humanity's responsibility to remember rightly. Using Volf's theology of remembering as an interpretive lens, I analyze characters’ inability to remember rightly while recalling partial memories of their trauma. In virtue of this examination, I contend that memory altering technologies may inhibit individuals from relational processes of healing, such as forgiveness. Consequently, I argue that this study leads to a richer understanding of the potential that memory altering technologies have for undermining humanity's ability to interact in a relational capacity, specifically in terms of forgiveness.     

Reliability and validity of the Multiple Affect Adjective Check List - Revised

A recent factor analysis of the Multiple Affect Adjective Check List (MAACL) changed the Anxiety, Depression, and Hostility scales from bipolar to unipolar scales and added two new scales: Positive Affect and Sensation Seeking. Internal reliability of the MAACL-R scales, computed for normal and patient samples, was adequate for state and trait forms except for Sensation Seeking. Test-retest reliability in college students was higher for the trait form with retest intervals of from 2 to 8 weeks than for the state form with retest intervals of from 2 to 5 days. The pattern of correlations among self-, peer, and counselor ratings and the MAACL-R scales for normal and patient samples indicates improved discriminant validity and equally good convergent validity as the old scales. The use of standard scores that are indexed to the number of items checked reduced scale intercorrelations by controlling the acquiescence set.The financial support of the Weldon Springs Endowment Fund, University of Missouri at Kansas City, toward the completion of this research project is gratefully acknowledged.
