The vocational well-being of workers with childhood onset of disability: Life satisfaction and perceived workplace discrimination

Workers with disabilities are understudied, and workers with childhood onset of disability have been excluded from many of the studies on disability and work that do exist. This research compares the effects of childhood and adult onset of disability in a nationally representative sample of workers with disabilities. Educational disruptions due to disability status in childhood are negatively associated with life satisfaction and positively associated with perceived discrimination. Although age is associated with increased life satisfaction and decreased perceptions of discrimination for workers with adult disability onset, age is unrelated to these outcomes for workers with childhood disability onset. Receiving workplace accommodations is positively associated with satisfaction and negatively associated with discrimination for both groups, however, these relationships are stronger in magnitude for the childhood disability onset group. Organizational environments, both in education and in the workplace, play a critical role in the vocational well-being of workers with childhood disability onset.     

Personal Income and Attitudes toward Redistribution: A Study of Lottery Winners

In order to estimate the effects of affluence on political attitudes, we conducted interviews with 342 people who had won the lottery between 1983 and 2000 in an Eastern state. A parallel survey of the general public was also conducted. Comparing winners of varying amounts, we find that lottery-induced affluence increases hostility toward estate taxes, marginally increases hostility towards government redistribution, but has little effect on broader attitudes concerning economic stratification or the role of government as a provider of social insurance. These results bolster previous findings suggesting that economic self-interest influences policy preferences when policy consequences are perceived as salient. At the same time, the findings suggest the limited influence that material concerns have on one's broad political outlook.     

Acquisition of route and survey knowledge in the absence of vision

The ability of sighted, blindfolded individuals to navigate while walking was assessed in two types of tasks, one requiring knowledge of a route that previously had been navigated and another requiring more complex spatial inference or computation. A computerized measurement system monitored spatial position. The route tasks included maintenance of a heading, distance and turn reproduction and estimation, and turn production. The inferential task required completion of a multisegment pathway by returning directly to the origin. pathways were replicated at two different scales. Measures for the route-knowledge tasks indicated a substantial ability to navigate in the absence of visual cues. Route reproduction performance was particularly accurate despite intrinsic veering tendencies. A substantial increase in error was observed in the pattern-completion task. Errors in pathway completion increased with pathway complexity and were quite similar in the two scales. Correlational data suggested that performance on different route-knowledge tasks reflected differing underlying representations. The completion task led to a high correlation between absolute turn and distance error but had minimal correlations with the route tasks. The data suggest that a survey representation with some degree of scale independence was constructed for use in the pathway completion task.     

Communication Styles and Marital Satisfaction in Israeli and American Couples

This study examined the conflict-related communication styles of American and Israeli couples and how these communication styles related to marital satisfaction in the two groups. An Israeli sample was recruited from Israeli couples currently living in New York City; the American sample was selected from the friendship circles of the Israeli couples. In spite of the close social ties of the two groups, we predicted that the conflict-related communication styles of the Israelis would be less calm and rational than those of the Americans and that such rational modes of communication would be positively associated with marital satisfaction for the Americans but not for the Israelis. The principle instruments were Straus' Conflict Tactics Scale, Ryder's Imagined Situation Inventory, and Spanier's Dyadic Adjustment Scale. Results largely confirmed the hypotheses. Israeli couples were more apt to be verbally aggressive (but less physically violent) and less apt to behave calmly during marital conflict, but these communication styles did not relate to marital satisfaction as strongly for the Israelis as for the Americans. These findings are discussed as a demonstration of the importance of considering cultural context when treating families.     

A Bayesian prediction of four-look recognition performance from one-look data: II

In a recent paper, four-look recognition performance was predicted from one-look (lL) data by Bayes’s theorem, with the entire pattern of two Ss’ four-look data being predicted reasonably well. In the present study, three Ss were run, with the addition that feedback was given and confidence judgments were required. Their task was to identify tachistoscopically presented graphemes A, T, or U. Predictions of four-look performance were made using three orders of lL data matrices, differing in the breakdown of confidence categories. The three matrices led to reasonably accurate predictions. Predictions varied somewhat in accuracy, depending on the order of the lL matrix. The possibility that the variation in predictive accuracy reflected the capacity of an S to combine information received from each observation was discussed. The capacity question is presently under investigation by the authors.     

The influence of cue unreliability on judgment in a multiple cue probability learning task

The effect of cue reliability was tested in a two-cue multiple-cue probability learning (MCPL) task. Subjects were 42 undergraduates. The cue validities were.78 and.37. Unreliability in a cue was defined as variability in multiple observations of that cue on a given trial. That variability was provided by adding random errors to the true value of the cue. One group was given consistent cues (i.e., the more valid cue was the more reliable cue), one group was given inconsistent cues, and the control group was given true scores. Cue reliability did not affect subjects' consistency or achievement, but did interact with the presence of outcome feedback. The subjective weights showed that subjects thought they weighted the more reliable cue more heavily regardless of the cue validities or their actual cue weightings. There were wide individual differences in performance, illustrating the need for an idiographic-statistical approach in studying decision making.     

Visual masking by light offset

Two experiments are reported which investigated whether or not the offset of light can serve as a backward masking stimulus (MS). In both studies, human Os made identification responses to graphemes (TS) presented tachistoscopically on a lighted field. Simultaneously with or at short intervals after TS offset, the lighted background field was shut off. The termination of the background field served as the MS. The results indicated a reliable masking effect due to light
