An eye-movement-contingent probe paradigm

A new eye-movement-contingent probe task is presented in which readers’ eye movements are monitored as they read sentences and respond to a probe word; the timing of the display of the probe word is dependent on fixation of a target word. The present study examined semantic priming effects. The target word was either related (doctor) or unrelated (lawyer) to the probe word (nurse), and the probe appeared 120, 250, 500, or 750msec after the reader first fixated on the target word. When the probe word appeared (in the location of the target word), the rest of the sentence disappeared until the participant named the probe word. Then the sentence reappeared, and the participant continued reading the sentence. Naming times to the probe word were recorded, as was sentence reading time and the eye movement behavior relative to the onset of the probe word. Priming effects were observed, since probe reaction time to related probes was faster than that to unrelated probes. Ways in which this paradigm can be used to study various issues in language processing are discussed.     

'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.     

Do current connectionist learning models account for reading development in different languages?

Learning to read a relatively irregular orthography, such as English, is harder and takes longer than learning to read a relatively regular orthography, such as German. At the end of grade 1, the difference in reading performance on a simple set of words and nonwords is quite dramatic. Whereas children using regular orthographies are already close to ceiling, English children read only about 40% of the words and nonwords correctly. It takes almost 4 years for English children to come close to the reading level of their German peers. In the present study, we investigated to what extent recent connectionist learning models are capable of simulating this cross-language learning rate effect as measured by nonword decoding accuracy. We implemented German and English versions of two major connectionist reading models, Plaut et al.'s (Plaut, D. C., McClelland, J. L., Seidenberg, M. S., & Patterson, K. (1996). Understanding normal and impaired word reading: computational principles in quasi-regular domains. Psychological Review, 103, 56-115) parallel distributed model and Zorzi et al.'s (Zorzi, M., Houghton, G., & Butterworth, B. (1998a). Two routes or one in reading aloud? A connectionist dual-process model. Journal of Experimental Psychology: Human Perception and Performance, 24, 1131-1161); two-layer associative network. While both models predicted an overall advantage for the more regular orthography (i.e. German over English), they failed to predict that the difference between children learning to read regular versus irregular orthographies is larger earlier on. Further investigations showed that the two-layer network could be brought to simulate the cross-language learning rate effect when cross-language differences in teaching methods (phonics versus whole-word approach) were taken into account. The present work thus shows that in order to adequately capture the pattern of reading acquisition displayed by children, current connectionist models must not only be sensitive to the statistical structure of spelling-to-sound relations but also to the way reading is taught in different countries.     

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.     

The politics of a conversion – the case of Robert Isaac Wilberforce

Robert Isaac Wilberforce (1802–1857) was an Anglican archdeacon and a supporter of the Oxford Movement. This article claims that his conversion to the Roman Catholic Church in 1854 had theo-political dimensions. To Wilberforce the constitutional establishment of the Church of England was not only a question of political pragmatics. His sacramental vision of the Church and his diagnosis of the actual ecclesiastical situation in England as ‘Erastian’ meant that his conversion could be seen as an act of existential political theology. His conversion is a strong suggestion that the Oxford Movement needs to be considered both as a spiritual and a political force in nineteenth-century England.     

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.

A randomized trial of employment-based reinforcement of cocaine abstinence in injection drug users

High-magnitude and long-duration abstinence reinforcement can promote drug abstinence but can be difficult to finance. Employment may be a vehicle for arranging high-magnitude and long-duration abstinence reinforcement. This study determined if employment-based abstinence reinforcement could increase cocaine abstinence in adults who inject drugs and use cocaine during methadone treatment. Participants could work 4 hr every weekday in a workplace where they could earn about $10.00 per hour in vouchers; they were required to provide routine urine samples. Participants who attended the workplace and provided cocaine-positive urine samples during the initial 4 weeks were invited to work 26 weeks and were randomly assigned to an abstinence-and-work (n = 28) or work-only (n = 28) group. Abstinence-and-work participants had to provide urine samples showing cocaine abstinence to work and maintain maximum pay. Work-only participants could work independent of their urinalysis results. Abstinence-and-work participants provided more (p = .004; OR = 5.80, 95% CI = 2.03-16.56) cocaine-negative urine samples (29%) than did work-only participants (10%). Employment-based abstinence reinforcement can increase cocaine abstinence.     

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.
