Working with the institutionalized aged and their families: Considerations for clergy

The institutionalization of an aged parent presents unique challenges and strains to the family system. It also provides opportunities for limited intervention and support by empathic clergy. It is often difficult for middle-aged children to understand some of the strong and often sudden emotions they experience regarding their institutionalized parents, particularly as these feelings become confused with their own sense of having reached middle age. Again, opportunities present themselves for clergy to be sensitive to these confusing feelings.     

Influences of test expectations on memory-processing strategies

In a series of four experiments, recall and recognition performance were examined following recall and recognition instructions. It was found that recall-instructed subjects produced significantly better performance than recognition-instructed subjects on tests of ordered and free recall of words, particularly on the early part of the list (Experiments 1 and 2). The results of two further experiments suggest that this is mediated by differences occurring at input, and is due to increased rehearsal by subjects expecting a recall test (Experiments 3 and 4).     

Visual attention at three months as a predictor of cognitive functioning at two years of age

The purpose of the present study was to examine the predictive power of various cognitive skills at 3 months of age in terms of later cognitive functioning. Habituating to redundant and recovering to novel stimuli at 3 months of age were found to predict later intellectual functioning at 24 months better than 3-month global intelligence or object permanence scores. In terms of information processing skills, recovery predicted later intelligence test scores better than habituation. It is suggested that changes in cognitive functioning may be viewed as a transformation of skills from one age to another rather than as a continuum of the same skills. With regard to the cognitive abilities of the 3-month-old, it is suggested that information processing may be central to cognitive functioning at this age.     

Neonates' heart rate,sucking rhythm,and sucking amplitude as a function of the sweet taste

In previous studies of human newborn sucking, the effects of increasing fluid sweetness and/or volume included a decrease in sucking rate within sucking bursts and, paradoxically, an increase in heart rate. To determine whether the heart rate increase can be attributed to increased sucking amplitude for sweeter fluids, sucking and heart rates of 20 full-term infants were studied. Half sucked for three consecutive 2-min periods, first receiving small drops of water for each suck, then no fluid, then 15% sucrose. The other half experienced the reverse order. The results for sucking and heart rate were consistent with previous studies; sucking rates within bursts were slowest for sucrose and fastest for no fluid. Heart rate was higher for sucrose than for the other fluid conditions, however, only in the water-first group. The heart rate increase was significant on statistical tests which controlled for sucking amplitude as well as for several other motor variables. Sucking amplitude itself varied with fluid sweetness in the water-first group only, in which it was highest for water. There were more total sucks, longer sucking bursts, and less time between successive bursts under the sucrose condition. Multivariate statistics helped establish a set of dependent variables—sucking rate within bursts, total number of sucks, and heart rate—which most parsimoniously describes the effects of fluid sweetness. A hedonic explanation of the response of newborns to sweetness is thus reiterated.     

Environmental factors and sense of community in a planned town

Previous community psychology research has suggested that sense of community can be a powerful explanatory tool for understanding community development and individual well-being, but has not focused on the relationship of environmental variables to the construct. In other disciplines—especially urban planning—this construct has received more attention but it has not been empirically and systematically studied. The three-phase qualitative study reported here sampled people representative of those who live and work in Seaside, FL, a town designed to induced sense of community. The data strongly suggest a relationship between a variable set that may define sense of community—membership, need fulfillment, shared emotional connections, loyalty—and the environmental variables of town design, architecture, and urban planning philosophy.     

participating in a couples therapy outcome study: Participants' views

Discovering that participants who received therapy in a research project and were being debriefed in a therapy outcome study considered those assessment sessions therapeutic, the authors conclude that participants: (a) are aware of the research context, (b) have some idea about how it affected the treatment they got, and (c) see positive outcomes for taking part in the study. Assessment and treatment were not separated in the minds of some participants, as they had been in the mind of the researchers.This study was supported in part by National Institute on Drug Abuse grant #1R 18DA 1069232001.     

A comparative analysis of the effects of social skill training and teacher-directed contingencies on social behavior of preschool children with disabilities

This study investigated the effects of an analog social skill training program and a teacher-directed contingency strategy on promoting social responding among four preschool children with mild disabilities and their peers. The social skill training program consisted of five lessons targeting the skill areas: Initiating, responding, and maintaining social interactions. The teacher directed contingency consisted of prompting target children when they were not socially involved with peers, and providing verbal praise when they were socially involved with peers. Subjects were divided into two training pairs and received both interventions in a reversal design. Presentation order was counterbalanced across the two training pairs. Results indicated that the teacher directed contingency was more effective in promoting higher levels of social responding in a free-play setting. Results also suggest that social skill training may not always be a necessary prerequisite to promote increased social interactions among children who display low rates of social interaction with peers, but possess necessary skills.     

A study of the classification capabilities of neural networks using unsupervised learning: A comparison withK-means clustering

Several neural networks have been proposed in the general literature for pattern recognition and clustering, but little empirical comparison with traditional methods has been done. The results reported here compare neural networks using Kohonen learning with a traditional clustering method (K-means) in an experimental design using simulated data with known cluster solutions. Two types of neural networks were examined, both of which used unsupervised learning to perform the clustering. One used Kohonen learning with a conscience and the other used Kohonen learning without a conscience mechanism. The performance of these nets was examined with respect to changes in the number of attributes, the number of clusters, and the amount of error in the data. Generally, theK-means procedure had fewer points misclassified while the classification accuracy of neural networks worsened as the number of clusters in the data increased from two to five.Acknowledgements: Sara Dickson, Vidya Nair, and Beth Means assisted with the neural network analyses.
