Understanding Respite Care Use by Families of Children Receiving Short-Term, In-Home Psychiatric Emergency Services

Respite care is widely believed to be an important support service for families raising a child with a disability. We report the findings of a respite care utilization study conducted within the context of a larger research and demonstration project examining three models of intensive, in-home services for children experiencing psychiatric crises. Respite care, both in-home and out-of-home, was a support service available to families in two of the three study conditions. Overall, 34% of 146 eligible families used in-home and or out-of-home respite care. Utilization was lower than the estimates developed prior to implementation, prompting an inquiry at the end of the first project year designed to maximize use and to gather more information on caregiver and service provider attitudes toward respite care. The inquiry included caregiver and provider focus groups, surveys, and enhanced data collection and analysis. Caregiver interviews indicated that many families did not fully understand what it meant to receive respite care or even that it was available to them. A comparative analysis of respite care users and non-users revealed that respite care users were more likely to have younger children, children who had a greater number of assessed functional impairments, and fewer social supports. Respite care users also reported greater difficulty managing their children's difficult behaviors.     

Attention and probabilistic sequence learning

Limitations of using fixed sequences of events in studies of learning in the sequential reaction-time task led us to develop a probabilistic version of the task. When sequences occur probabilistically, transitions usually follow a sequence, but with some small probability, events occur out of sequence. This variation on the paradigm provides new evidence associated with manipulations of attentional load. Most notably, single-task learning leads to particularly high error rates on improbable transitions, suggesting anticipation of the sequence. Dual-task learning shows sensitivity to the sequence (by reaction-time differences to probable and improbable transitions), but without inflated errors on improbable transitions. Sensitivity to the sequence and anticipatory errors disappeared when participants transferred from single-task learning to dual-task conditions, suggesting that what is learned with single-task practice cannot be applied under conditions of limited attention. When learners transferred from dual- to single-task conditions, sensitivity of RT to the sequence increased but anticipation errors remained the same, suggesting that attentional load limits performance, but not learning. Qualitative differences in performance result from variations in attentional resources, which may reflect different learning processes. Received: 17 February 1997 / Accepted: 5 January 1998     

Is a Tenseless Language Possible?

Whether it takes the form of a translation or of giving truth-conditions, any putative reduction of tensed language to tenseless language will be undermined if it can be shown that there could be no genuinely tenseless language. A similar problem faced traditional phenomenalism: it was far from clear that there could be a 'language of sense-data'. Either the imagined language was no language at all, or it was dependent upon object-language, not the other way around. A parallel dilemma faces tenseless reductionism. In spelling out what a tenseless language would be like, one either ends up with something that no creature could have as a language, or with something that is parasitic upon tensed language - not the other way around.     

A family intervention in psychosis service integrating the systemic and family management approaches

A project to establish new family intervention services to support people with psychotic symptoms and their families is described. The new services are developed by training a whole team in each main population centre. The multidisciplinary training course and the family intervention service are described, and the way in which we integrate the 'family management' and 'family therapy' approaches is discussed.     

Exploring collaborative problem solving in adulthood

Collaborative problem solving occurs in situations in which two or more individuals cooperate in appraising, representing, and solving a variety of cognitive tasks. Collaborative groups are the context for much everyday cognitive activity in adulthood. Collaboration has been explored as a means through which older adults may maintain high levels of performance, perhaps compensating for individual-level cognitive and neurological decline. This study explored the effects of collaboration (group size) and adult age on solving both fixed- and unrestricted-alternatives 20 Questions tasks. Younger (M=24.3 years) and older (M=67.9 years) adults were randomly assigned to one of three homogeneous group size conditions: individuals, dyads, and tetrads. Results indicated some dissociation between individual-level performance (poorer for older adults) and collaborative performance (better for older adults). For the fixed-alternatives task, older adults produced more of the relatively inefficient hypothesis-scanning questions than did younger adults. In contrast, older collaborative groups produced more of the efficient constraint-seeking questions than hhpothesis-scanning questions, and an amount equivalent to that of younger adults. Overall performance for the difficult unrestricted-alternatives task was less efficient for both younger and older adults. The roles of task type, group characteristics, and adult age are discussed.     

Individual differences in the vibrotactile perception of a “simple” pattern set

Discriminative capacities for vibrotactile spatiotemporal patterns were examined in 62 college students with three tasks: identification, masking, and discrimination of the letters “X” and “O” presented tactually on the Optacon, a reading machine for blind persons. Individual differences in performance and interrelations among scores within and across paradigms were explored. In identification, most persons quickly achieved consistently better than 90% performance, but others failed to identify the patterns above 80%, even after prolonged training. The same performance variance was found when the task was repeated by 23 Naval student pilots. Masking and discrimination measured susceptibility to interference when patterns followed one another closely in time. The resulting functions were typical, with poorest performance at short stimulus onset asynchronies. Again, a wide range of performance was seen. Individual performance, however, appeared to be consistent across tasks, suggesting that abilities in a variety of pattern-perception tasks might be predictable.     

Detecting group differences in sequential association using sampled permutations: Log odds,kappa, and phi compared

When determining whether a particular transition is more characteristic of one group than of another, two things are required: an index associated with the transition of interest and a statistical test that can determine whether group membership systematically affects values for that index. Here the familiar parametrict test is compared with a test based on sampled permutations. Indices considered are the odds and log odds ratio, Yule’sQ, Wampold’s (1989) transformed kappa, and phi. The odds and log odds ratio are monotonically increasing functions of Yule’sQ and so give similar results. Yule’sQ and phi are essentially rank order invariant and usually give similar results. Transformed kappa, however, rank orders subjects somewhat differently than the others; moreover, it appears somewhat biased. With respect to the tests, when subjects are 20 or more it does not matter much whether sampled permutation or parametrict tests are used; both yield essentially the same result. However, when subjects are fewer than 20, or whenever there is any other reason to think that parametric assumptions may not be met, permutation tests are recommended. A computer program that effects such tests is described.     

Political attitudes: Interactions of cognition and affect

Commonly held political opinions provide an ecologically relevant focus for studying the interactions of environmental context, affect or emotion, and cognition. To explore this approach to information processing, John T. Lanzetta helped initiate a series of experiments examining how emotional responses to politicians' nonverbal displays influence changes in attitude toward these leaders. Although this line of research has revealed how a number of variables interact when humans respond to known individuals in meaningful situations, the precise relationship between mood state or affect prior to a stimulus and subsequent emotions and cognitions remains unclear. Based on recent theories of modular brain function, an experimental paradigm was designed to test the hypothesis that the effects of a mood state on information processing depend on the subject's awareness of the affect as well as on its valence. Preliminary data from such a study, in which preconscious images of emotionally evocative stimuli were used to induce positive or negative affect prior to viewing the leader, suggests that the induction of negative affective states can lead to more positive attitudes. Reflected in such public opinion phenomena as the rally-round-the-flag effect, this mood-incongruent attitude change challenges many traditional theories of emotion and cognition.This research was supported by the Nelson A.

Stress,coping, HIV status,psychosocial resources,and depressive mood in African American gay,bisexual, and heterosexual men

The associations between stress, physical health, psychosocial resources, coping, and depressive mood were examined in a community sample of African American gay, bisexual, and heterosexual men (N=139). Data were collected from physical exams and in-person interviews. In our theoretical framework, depressive mood scores were regressed first on stressors, next on psychosocial resources, and finally on coping strategy variables. Results revealed that psychosocial resources mediate the effects of stressors, including health symptoms, hassles, and life events, on depressive mood. There were no significant differences in depressive mood associated with HIV status or sexual orientation. Results are discussed in terms of community interventions needed to provide social support as a buffer between stress and psychological distress in African American men. The research was completed at the Center for AIDS Prevention Studies, University of California at San Francisco and was supported in part by National Institute of Mental Health Grants MH44045 and MH42459. The authors express their appreciation to the participants in this study.     

Synergetic Counseling and Native American Indian Students

Traditional school counseling efforts have often failed to meet the needs of Native American Indian students. Because many Native American Indian students have spiritual as well as secular concerns, school counselors must become more emphatic and competent in serving these students. This article argues that synergetic counseling efforts with Native American Indian students increase counseling effectiveness. A vignette and suggestions are offered toward that end.
