AN ANALYSIS OF THE PROCEDURAL COMPONENTS OF SUPPORTED EMPLOYMENT PROGRAMS ASSOCIATED WITH EMPLOYMENT OUTCOMES

This study examined the relation between the procedural components of supported employment programs and employment outcomes for 120 individuals with disabilities. These individuals were involved in supported employment programs established through the Utah Supported Employment Project. The results suggest that successful implementation of supported employment services led to ongoing employment of study participants in community work sites, increased wages, and ongoing opportunities for workers to interact with nondisabled peers. In addition, several procedural components were found to be strongly associated with successful employment outcomes for workers. Results of the study are discussed in terms of the training needs of supported employment program staff and future research for the dissemination of a cohesive technology of supported employment.     

The University of South Florida homograph norms

Norms were collected to determine the relative dominance of different meanings of homo-graphic words. Forty-six subjects wrote down the first word that came to mind for each of 320 homographs. Each homograph, the number of times each meaning was given, and the specific associates are made available. In addition, correlations with other norms are presented.     

Beliefs about overcoming psychological problems among British and Japanese students

This study was part of a series investigating lay attributions for the cure of psychological problems. Three groups of students--Japanese students in Japan, Japanese students studying in England, and British students--completed a questionnaire and rated the perceived efficacy of 24 different strategies for overcoming each of 5 psychological problems: agoraphobia, depression, smoking cessation, lack of confidence, and obesity. Factor analysis of the curative strategies revealed 5 interpretable factors, the first 3 of which were Professional Help, Inner Control, and Understanding. There were numerous cultural differences between the British group and both Japanese groups in their written ratings of strategies, particularly professional help, for each psychological problem.     

What is free association and what does it measure?

This paper reports the results of a study of free association in which participants were asked to produce the first two words to come to mind. The findings were used to estimate the reliability of indices of strength and set size for different types of items and to model free association as a retrieval task. When confined to first responses, reliability was generally high for both indices, particularly for words with smaller sets of associates and stronger primaries. When second responses were included, reliability declined. A second response added new but weak items to the set, and, when the primary associate was not produced on the first opportunity, it tended not to be produced on the second. Relative to when multiple responses are requested, first-response free association provides more reliable indices of the relative strength and set size for a word's strongest associates. A model of free association assuming that a strength distribution underlies each response provided a good fit to the data.     

Older adults as adaptive decision makers: evidence from the Iowa Gambling Task

Older adults process emotional information differently than younger adults and may demonstrate less of a negativity bias on cognitive tasks. The Iowa Gambling Task designed by A. Bechara, H. Damasio, D. Tranel, and A. R. Damasio (1997) has been used to examine the integration of emotion and cognition in a risky-choice decision task and may give insight into differences in the decision-making strategies in younger and older adults. Eighty-eight younger adults (18-34 years) and 67 older adults (65-88 years) completed the Iowa Gambling Task. Using a theoretical decomposition of the task designed by J. R. Busemeyer and J. C. Stout (2002), the authors found that both groups were successful at solving the task but used very different strategies that reflected each group's strength. For younger adults, that strength was learning and memory. For older adults, that strength was an accurate representation of wins and losses (valence).     

Impaired modulation of corticospinal excitability following subthreshold rTMS in focal hand dystonia

Previous studies have demonstrated that subthreshold 1 Hz repetitive transcranial magnetic stimulation (rTMS) causes a decrease in corticospinal excitability in neurologically normal subjects. The effects of subthreshold 1 Hz rTMS upon corticospinal excitability and intracortical inhibition in subjects with focal hand dystonia (FHD) is not yet clear. The purpose of this study was to examine the effects of low intensity 1 Hz rTMS upon these variables in control and FHD subjects. We recorded electromyographic (EMG) from the first dorsal interosseous (FDI) muscle of the dominant hands of seven control subjects, and seven affected hands of five FHD subjects. We used single and paired pulse TMS to examine motor evoked potential (MEP) amplitude, short interval intracortical inhibition (ICI) and silent period duration before, during and after 20 min of low intensity 1 Hz rTMS. MEP amplitude decreased significantly over the course of the rTMS in control subjects, but did not change in FHD subjects. Silent period duration was significantly longer in control subjects after rTMS, but there was no change in FHD subjects. There was no significant change in ICI after rTMS in either subject group, despite the rTMS intensity being set to preferentially activate intracortical inhibitory networks. This suggests that low intensity 1 Hz rTMS may have limited application in the normalisation of inhibitory function in FHD.     

Recovery and predictors of language skills two years following pediatric traumatic brain injury

Subtle language processing difficulties may adversely affect scholastic performance, as well as communication and social skills. It is therefore crucial that language skills are monitored following traumatic brain injury (TBI) in childhood. The present study examined language skills in a group of 68 children who had sustained a mild, moderate or severe TBI. Results indicated that during the acute stage a dose-response relationship was evident, where severe TBI was associated with poorest performance and mild TBI with least deficits. By 24 months post-TBI, it was clear that for some language functions, the severe TBI group showed substantial recovery, and at times performed better than the moderate TBI group. Predictors of language and literacy skills at 24 months post TBI included pre-injury communication skills, socio-economic status, age at injury, and Vocabulary, as measured by the Wechsler Intelligence Scale for Children (WISC-111).     

Gender-typical responses to sexual and emotional infidelity as a function of mortality salience induced self-esteem striving

The authors propose that gender-differentiated patterns of jealousy in response to sexual and emotional infidelity are engendered by the differential impact of each event on self-esteem for men and women. Study 1 demonstrated that men derive relatively more self-esteem from their sex lives, whereas women's self-esteem is more contingent on romantic commitment. Based on terror management theory, it is predicted that if gender-differentiated responses to infidelity are motivated by gender-specific contingencies for self-esteem, they should be intensified following reminders of mortality. In Study 2, mortality salience (MS) increased distress in response to sexual infidelity for men and emotional infidelity for women. Study 3 demonstrated that following MS, men who place high value on sex in romantic relationships exhibited greater distress in response to sexual infidelity, but low-ex-value men's distress was attenuated. The authors discuss the implications for evolutionary and self-esteem-based accounts of jealousy as well as possible integration of these perspectives.     

Spreading activation or spooky action at a distance?

How do preexisting connections among a word's associates facilitate its cued recall and recognition? A spreading-activation model assumes activation spreads to, among, and from a studied word's associates, and that its return is what strengthens its representation. An activation-at-a-distance model assumes strengthening is produced by the synchronous activation of the word's associates. The spread model predicts that connections among the studied word's associates will have a greater effect on memory when more of its associates return activation. The distance model predicts that total connections are important, not their direction. The results of cued recall experiments supported the distance model in showing that that connections among the associates facilitated recall regardless of the number of returning connections.
