'Minor GAD': characteristics of subsyndromal GAD in older adults

Subsyndromal emotional symptoms are common in older adults and are associated with increased disability, health care utilization, and risk for developing psychiatric disorders. The purpose of this study was to examine subsyndromal generalized anxiety disorder (GAD) in older adults. Participants included 30 older adults with diagnosable GAD, 19 with subsyndromal anxiety symptoms [minor GAD; (MGAD)], and 21 normal control volunteers (NC). Participants were assessed using the Anxiety Disorders Interview Schedule for DSM-IV and completed self-report measures of anxiety, worry, depression, and life satisfaction. Excessive worry on more days than not, difficulty controlling worry, and clinically significant distress or impairment were the diagnostic criteria endorsed by MGAD participants least often. Therefore, these criteria may be useful in distinguishing between GAD and subsyndromal GAD. Self-reported anxiety and worry also systematically differed across groups in the expected directions, with a discriminant analysis yielding good classification of the GAD and NC groups based on these measures. Categorization of MGAD participants generally was poor, with most misclassified as GAD patients. Clinical implications of these findings are discussed.     

The staying power of intercultural learning through reflective inquiry

This paper focuses on the staying power of intercultural knowledge, skills and attitudes for adult students who were engaged in reflective inquiry during a travel course. It addresses a need to assess whether new learning gained from reflection on experience persists over time and what factors may influence staying power. The main finding of the study is that intercultural competence developed through reflective inquiry is maintained and often deepened over time. This builds upon previous findings that skills and characteristics of effective intercultural interaction are advanced through using reflective inquiry to analyze observations and resolve puzzling problems triggered by uncertainty. The context for this qualitative inquiry is with undergraduate adult students participating in a travel course designed to develop intercultural competence. They responded to reflective prompts throughout the course and 18 months after completion. Cases are presented that analyze course and post-course responses. I conclude that the intersection of reflective inquiry and intercultural competence frameworks can influence the ongoing persistence of learning over time.     

Examination of the Hamilton Scales in Assessment of Anxious Older Adults: A Replication and Extension

This study examined the original and reconstructed Hamilton scales in the assessment of anxiety and depression in a sample of older adults diagnosed with GAD (n = 82). Internal consistency of all scales appeared adequate. Results indicated improved construct validity with the reconstructed scales, which demonstrated reduced shared variance. However, construct validity examined through intercorrelations of the Hamilton scales with self-report measures of anxiety and depression was generally poor. Discriminant function analysis indicated that the reconstructed scales might have some clinical utility in differentiation of patients with and without coexistent depressive diagnosis (67% correct classification). In addition, two items from the Hamilton rating scale for depression (Work and Activities; Hopelessness) correctly classified patients with and without depression at a similar level as the Hamilton scale total scores (64–65% correct classification). These results suggest that the Work and Activities, and Hopelessness items may provide clinicians with useful screening questions for depression in anxious older adults.     

Action,inaction, and factors influencing perceived decision making

Two studies examined factors hypothesized to be related to the subjective perception of decision making. A total of 302 introductory psychology students read four hypothetical scenarios that varied on two dimensions: frequency of the behavior and whether the behavior was an action or an inaction (a 2 × 2 design). Subjects rated the scenarios on whether the actor made a decision. In Experiment 1, the frequency of behavior was unrelated to decision making. In addition, actions were given higher decision ratings than inactions in two scenarios, but lower ratings in the other two scenarios. In Experiment 2 the latter discrepancy was explained by ratings of whether the actor behaved thoughtfully rather than reflexively, in that these ratings mediated the action–decision rating relationship.

Intuitive<Emphasis Type="Italic">t</Emphasis> tests: Lay use of statistical information

Normatively, a statistical pairwise comparison is a function of the mean, standard deviation (SD), and sample size of the data. In our experiment, 203 undergraduates compared product pairs and judged their confidence that one product was better than the other. We experimentally manipulated (within subjects) the average product ratings, the number of raters (sample size), and theSD of the ratings. Each factor had two levels selected, so that the same change in statistical power resulted from moving from the low to the high level. We also manipulated (between subjects) whether subjects were given only the product rating data as summarized in a statistical format or the summaries plus the raw ratings. Subjects gave the most weight to mean product ratings, less weight to sample size, and very little weight toSD. Providing subjects with raw data did not increase their use of sample size andSD, as predicted.     

An encounter frequency account of how experience affects likelihood estimation

When making judgments, people often favor information received from a few individual sources over largesample statistical data. Individual information is usually acquired piece by piece, whereas statistical information combines many observations into a single summary. We examined whether this difference in the frequency of encounters affects how data are weighted. In two experiments, subjects read statistical information indicating an event to be rare and contrasting information from individual cases suggesting the event to be common. We controlled whether the individual cases were summarized into a single summary like statistical information, or presented serially, case by case. Subjects’ estimates of event frequencies were higher when the individual cases were presented in serial, rather than summarized, format. A third study demonstrated that subjects treat each data sample as an instance, and do not weight according to sample size. These results support the conclusion that people weight information according to encounter frequency.     

The effect of clause wrap-up on eye movements during reading

The effect of clause wrap-up on eye movements in reading was examined. Readers read passages in which a target category noun referred to either a high typical or a low typical antecedent. In addition, the category noun was either clause final or non-clause final. There were four primary results: (1) Readers looked longer at a category noun when its antecedent was a low typical member of the category than when it was a high typical member; (2)readers looked longer at the category noun and at the post-category region when they were clause final than when they were not clause final; (3) readers regressed from a category noun or post-category region more frequently when it was clause final than when it was not clause final; and (4) readers made longer initial saccades when their eyes left the category noun or post-category region when this word was in clause final position than when it was not clause final. The last result suggests that sometimes higher order processes that are related to making a decision about when to move the eyes impinge on lower level decisions that are typically associated with deciding where to move the eyes.     

Science,Religious Naturalism,and Biblical Theology: Ground for the Emergence of Sustainable Living

During this century, humans must learn to live in ways that are sustainable, both ecologically and morally. The global community already consumes more ecological resources than Earth can generate; population growth and increasing development are widening that gap. We suggest that paths to sustainability can be found by mindful reflection on meanings discerned in the convergence of a scientific understanding of nature, religious naturalism, and biblical understandings of creation. The patterns of ecological sustainability observed in natural systems and the wise ways of relating to the land discerned in the Hebrew Bible suggest that sustainability must be grounded in social and ecological justice and that just ways of living can emerge from a deep sense of the ways in which nature and all of humanity are interdependent. We conclude that the twentieth-century emphasis on individual control of our future must make room for the emergence of a new understanding of mutuality. There can be no flourishing apart from mutual flourishing.     

Why Do People Like Natural? Instrumental and Ideational Bases for the Naturalness Preference

Naturalness preference refers to the tendency to prefer natural things to otherwise equivalent unnatural alternatives. Previous research suggests that the naturalness preference is largely due to ideational reasons (moral or aesthetic appeals), rather than instrumental reasons (inferred functional superiority), because the natural and unnatural alternatives were specified as identical. The current studies showed that people do not always believe that natural and unnatural alternatives can be identical. Responses that in previous studies would have been interpreted as ideational‐based naturalness preference were correlated with beliefs in instrumental advantages of natural products. We propose that instrumental and ideational reasons are closely connected, and instrumental beliefs may contribute to the “natural is better” heuristic. The financial consequence of naturalness preference was also demonstrated.     

Picture recognition of food by macaques (<Emphasis Type="Italic">Macaca silenus</Emphasis>)

Pictorial representations of three-dimensional objects are often used to investigate animal cognitive abilities; however, investigators rarely evaluate whether the animals conceptualize the two-dimensional image as the object it is intended to represent. We tested for picture recognition in lion-tailed macaques by presenting five monkeys with digitized images of familiar foods on a touch screen. Monkeys viewed images of two different foods and learned that they would receive a piece of the one they touched first. After demonstrating that they would reliably select images of their preferred foods on one set of foods, animals were transferred to images of a second set of familiar foods. We assumed that if the monkeys recognized the images, they would spontaneously select images of their preferred foods on the second set of foods. Three monkeys selected images of their preferred foods significantly more often than chance on their first transfer session. In an additional test of the monkeys’ picture recognition abilities, animals were presented with pairs of food images containing a medium-preference food paired with either a high-preference food or a low-preference food. The same three monkeys selected the medium-preference foods significantly more often when they were paired with low-preference foods and significantly less often when those same foods were paired with high-preference foods. Our novel design provided convincing evidence that macaques recognized the content of two-dimensional images on a touch screen. Results also suggested that the animals understood the connection between the two-dimensional images and the three-dimensional objects they represented.
