Impact of Psychoeducational Interventions on Distressed Family Caregivers

This study compared the effectiveness of two active interventions to a waiting-list control condition to reduce depression and burden and increase use of adaptive coping strategies in family caregivers (N = 161) of physically and/or cognitively impaired older adults. Chi-square analysis of change in depression status from pre- to postintervention showed a higher percentage of improvement among participants in the increasing life satisfaction psychoeducational condition compared to the improvement rate in either the problem-solving psychoeducational class or the wait-list condition. Change in coping strategies and subjective level of burden also differed by group, with participants in the class conditions reporting more frequent use of cognitive or behavioral coping strategies, and less subjective burden, from pre- to postintervention. There was no change in either avoidant coping or perceived stress over time. Results show that intervention programs targeted to improve specific coping skills and psychological symptoms can have a significant impact on caregivers' distress.     

Predicting the Use of Complementary Medicine: A Test of the Theories of Reasoned Action and Planned Behavior1

The present study employed the theory of reasoned action (TRA) and its extension, the theory of planned behavior (TPB), to investigate the factors underlying intentions and actual use of homeopathy over a 1‐month period. The study was prospective in design; 349 respondents completed a TPB questionnaire during the first phase of data collection, and 139 respondents were contacted (by telephone) in Phase 2 to provide information regarding their use of homeopathy. The findings provided support for the TPB as a predictor of intentions and use of homeopathy, and demonstrated that the model significantly enhanced the predictive utility of the TRA. Attitudes, subjective norms, and perceived control emerged as significant predictors of intention (R²= .49), while intention predicted behavior (R²= .56). In addition, past behavior significantly contributed to the prediction of intention and behavior.     

Written language acquisition after left or right hemidecortication in infancy

When written language is acquired in only one hemisphere because of hemidecortication in infancy, the left hemisphere is superior to the right at using morphophonemic rules to read and spell unfamiliar words, and at exploiting the structure of sentence units to achieve rapid reading of meaning in prose. The ability to learn names for logographs, however, is better in the right hemisphere than in the left. The greater mastery of written language in the left hemisphere is a result, not of an enhanced facility for making cross-modal associations between sounds and signs, but of a superior access to the morphophonemic rule system and the higher-order textual constraints of English.     

Sentential structure and the perceptual span in normal reading development

An eye-voice span paradigm was adopted to determine whether children use different aspects of sentence structure to facilitate decoding early in the course of reading development. Eightyfour Grade 1 and Grade 2 children, representing four levels of early reading competence, and 15 skilled adult subjects read from four textual conditions; materials varied in the extent to which the texts were semantically and/or syntactically constrained. The more precocious the young reader, the longer his reported span. The better readers' and the adults' advantage was greater the more linguistically constrained the reading material. These data support a continuous model fo reading development and are compatible with an interactive definition of early reading behavior.

Using analogical mapping to simulate time-course phenomena in perceptual similarity

We present a computational model of visual similarity. The model is based upon the idea that perceptual comparisons may utilize the same mapping processes as are used in analogy. We use the Structure Mapping Engine (SME), a model of Gentner’s structure-mapping theory of analogy, to perform comparison on representations that are automatically generated from visual input. By encoding visual scenes incrementally and sampling the output of SME at multiple stages in its processing, we are able to model not only the output of similarity judgments, but the time course of the comparison process. We demonstrate the model’s effectiveness by replicating the results from three psychological studies that bear on the time course of comparison.     

Extending SME to Handle Large‐Scale Cognitive Modeling

Analogy and similarity are central phenomena in human cognition, involved in processes ranging from visual perception to conceptual change. To capture this centrality requires that a model of comparison must be able to integrate with other processes and handle the size and complexity of the representations required by the tasks being modeled. This paper describes extensions to Structure‐Mapping Engine (SME) since its inception in 1986 that have increased its scope of operation. We first review the basic SME algorithm, describe psychological evidence for SME as a process model, and summarize its role in simulating similarity‐based retrieval and generalization. Then we describe five techniques now incorporated into the SME that have enabled it to tackle large‐scale modeling tasks: (a) Greedy merging rapidly constructs one or more best interpretations of a match in polynomial time: O(n²log(n)); (b) Incremental operation enables mappings to be extended as new information is retrieved or derived about the base or target, to model situations where information in a task is updated over time; (c) Ubiquitous predicates model the varying degrees to which items may suggest alignment; (d) Structural evaluation of analogical inferences models aspects of plausibility judgments; (e) Match filters enable large‐scale task models to communicate constraints to SME to influence the mapping process. We illustrate via examples from published studies how these enable it to capture a broader range of psychological phenomena than before.     

Equivalence‐based instruction to establish a textual activity schedule in an adult with Down syndrome

Transfer of control from picture to text‐based activity schedules has been shown to occur following conditional discrimination training in children with autism. This study extended this research by evaluating if conditional discrimination training could promote transfer of control in an adult with Down syndrome. The participant was taught to select photographs and pictures of kitchen tools when provided with dictated names. Then, he completed a text‐based activity schedule, matched printed words to photographs, and orally named printed words without direct training.
