The Effect of Mindfulness on Heart Rate Control

An experiment was conducted to test the hypothesis that mindful attention to change regarding heart rate (HR) would result in greater control over HR. Experimental groups monitored the changing or stable nature of HR, respectively. All participants’ HR slowed during the decrease phase. Participants whose attention was directed to the stable nature of HR performed the worst on the increase phase of the HR control task. These results suggest that mindfulness, instantiated here as attention to variability, is a means to increasing control.

Aging and semantic cueing during learning and retention of verbal episodic information

The purpose of this study was to determine the effectiveness of semantic cues provided at encoding and during retention for older adults' memory. For the California Verbal Learning Test-II, participants received semantic or nonsemantic cues that were varied across groups at encoding and during the retention interval. Provision of a semantic cue at encoding led to greater semantic clustering at learning, but not increased recall performance. Providing a semantic cue during the retention interval led to better delayed free recall and greater semantic clustering. No group differences in recall or semantic clustering were found at delayed cued recall. The current findings suggest that semantic cues can be beneficial for recalling unstructured information when administered during the retention interval.     

Sacred Places, Domestic Spaces: Material Culture, Church, and Home at Our Lady of the Assumption and St. Brigitta

The relationship between the material culture of public worship and congregants' homes is explored in a study of two Catholic parishes—theologically liberal St. Brigitta and conservative Our Lady of Assumption. At St. Brigitta, congregants' worship space is almost devoid of religious art and ritual objects are plain, but worshippers' homes are rich in decorative objects. By contrast, masses at Our Lady of the Assumption take place in a church filled with devotional art and ornate objects, but worshippers' homes are spare, neutrally furnished, and display few decorations. Distinct congregational logics surrounding the making of the self help to explain the material culture differences: St. Brigitta parishioners value individualized self-expression whereas Assumption's members subordinate individuality to family and church identities. Individuals use material objects not only for self-expression, but also to explicitly shape identities and make the self.     

Correction and use of biomedical literature affected by scientific misconduct

The purpose of this study was to identify and describe published research articles that were named in official findings of scientific misconduct and to investigate compliance with the administrative actions contained in these reports for corrections and retractions, as represented in PubMed. Between 1993 and 2001, 102 articles were named in either the NIH Guide for Grants and Contracts ("Findings of Scientific Misconduct") or the U.S. Office of Research Integrity annual reports as needing retraction or correction. In 2002, 98 of the 102 articles were indexed in PubMed. Eighty-five of these 98 articles had indexed corrections: 47 were retracted; 26 had an erratum; 12 had a correction described in the "comment" field. Thirteen had no correction, but 10 were linked to the NIH Guide "Findings of Scientific Misconduct", leaving only 3 articles with no indication of any sort of problem. As of May 2005, there were 5,393 citations to the 102 articles, with a median of 26 citations per article (range 0-592). Researchers should be alert to "Comments" linked to the NIH Guide as these are open access, and the "Findings of Scientific Misconduct' reports are often more informative than the statements about the retraction or correction found in the journals.     

An event-related potential study on the observation of erroneous everyday actions

Recent experiments have demonstrated that error-related negativity (ERN) is not only elicited when people commit errors, but also when they observe others committing errors. The present study investigates whether this observed ERN is also present when participants observe execution errors in an everyday context. Participants observed short sequences of pictures showing steps of everyday actions ending either erroneously or correctly. Participants were instructed to indicate by a delayed response whether the observed action was correctly executed or not. The results showed a large P300 for execution errors compared with the observation of correct sequences, but no ERN activity was found. The present experiment indicates that the detection of execution errors in observation does not rely on the error processing mechanism responsible for generating the ERN. The increased P300 amplitudes suggest a more general monitoring process that signals that the occurrence of unexpected events is involved in the detection of execution errors.     

Adult Age Differences in Dual Information Processes: Implications for the Role of Affective and Deliberative Processes in Older Adults' Decision Making

ABSTRACT— Age differences in affective/experiential and deliberative processes have important theoretical implications for judgment and decision theory and important pragmatic implications for older-adult decision making. Age-related declines in the efficiency of deliberative processes predict poorer-quality decisions as we age. However, age-related adaptive processes, including motivated selectivity in the use of deliberative capacity, an increased focus on emotional goals, and greater experience, predict better or worse decisions for older adults depending on the situation. The aim of the current review is to examine adult age differences in affective and deliberative information processes in order to understand their potential impact on judgments and decisions. We review evidence for the role of these dual processes in judgment and decision making and then review two representative life-span perspectives (based on aging-related changes to cognitive or motivational processes) on the interplay between these processes. We present relevant predictions for older-adult decisions and make note of contradictions and gaps that currently exist in the literature. Finally, we review the sparse evidence about age differences in decision making and how theories and findings regarding dual processes could be applied to decision theory and decision aiding. In particular, we focus on prospect theory ( Kahneman & Tversky, 1979 ) and how prospect theory and theories regarding age differences in information processing can inform one another.     

The association between body image and smoking cessation among individuals living with HIV/AIDS

Lower smoking cessation rates are associated with body image concerns in the general population. This relationship is particularly important to study in individuals living with HIV/AIDS due to alarmingly high smoking rates and considerable bodily changes experienced with HIV disease progression and treatment. The association between body image and smoking cessation rates was examined among individuals living with HIV/AIDS participating in a smoking cessation intervention. Body image concerns were significantly associated with depression, anxiety, stress, and social support, all variables known to affect cessation rates. However, reduced quit rates were found among individuals reporting elevated and low levels of body image concerns at the end of treatment. These findings suggest a unique relationship between smoking and body image among individuals living with HIV/AIDS. Further research is needed to examine these effects and whether moderate levels of body image concerns in this population reflect realistic body perceptions associated with positive mental health.
