Behavioral Microanalysis of Helping Interactions Between Mothers and Adult Children with Mental Retardation

Although direct observation has provided much information regarding caregiver-care recipient interactions, our understanding of the applications of this technique remains incomplete. This study expands upon earlier observational work by examining adults with mental retardation (MR) and their family caregivers in the home setting. Specialized computer software was used to conduct real-time observation and recording of interactional styles of maternal caregivers of eight younger (M = 23 years old) and eight older (M = 49 years old) MR adults during two cognitive tasks: block design and card sorting. Differences in the amount and type of assistance provided by the caregiver were examined by coding the occurrence and duration of seven interactional behaviors. The results demonstrated that the caregivers of the younger adults used more positive statements and modeling/gestural prompts, whereas the caregivers of the older adults provided more physical assistance and performed more of the tasks themselves. More importantly, this project provided information regarding interactions between MR adults and their maternal caregivers and demonstrated the utility of computer-assisted data collection technology with a community-based, nondemented population.     

Multiple effects of performance-contingent pay for wait-persons

The owners of three restaurants requested help with the pay of waitpersons who were paid by the hour. The waitpersons asked for raises which the owners said they could not afford. This research changed the method of compensating waitpersons by making their pay contingent on dollars of food sold. Increased productivity and increased earnings per hour of work for all of the waitpersons followed the beginning of the performance-contingent pay. Most of the waitpersons also earned increased take-home pay when the performance-contingent pay began. There was little improvement in labor costs per dollar of food sold, a measure of benefit to the owners. The fact that benefits to workers occurred without benefits to owners is contrary to common views about the effects of performance-contingent pay.     

Measuring emotional management abilities: Further evidence of the importance to distinguish between typical and maximum performance

Freudenthaler and Neubauer (2005) have recently developed and validated performance measures of emotional management abilities (EMA), requiring subjects to indicate their typical behaviour in emotional situations (typical-performance instruction, TP) instead of assessing the effectiveness of different behavioural alternatives or indicating the most adequate response (maximum-performance instruction, MP). In the present study (n = 176), we examined the effects of these two instruction forms (TP vs. MP) on the EMA-scores in a between-subject design. In addition, the relations of typical and maximum EMA to cognitive intelligence components and personality traits were tested. Instruction-related comparisons of the EMA-scores yielded not only lower means but also higher standard deviations and higher reliabilities in the TP-condition. As expected, maximum EMA were significantly correlated with cognitive intelligence components but not with personality traits. In contrast, the typical EMA were moderately associated with personality traits but not related to cognitive abilities, providing further evidence of the importance to distinguish between typical and maximum performance.     

Effects of Pro-Environmental Recruiting Messages: The Role of Organizational Reputation

Purpose  The purpose of this study was to examine the effects of a pro-environmental corporate message on prospective applicants’ attitudes toward a fictitious hiring organization. Drawing from signaling theory, we hypothesized that an environmental message on the organization’s recruitment website would increase prospective applicants’ perceptions of organizational prestige, which would then increase job pursuit intentions. Personal environmental attitudes were also examined as a possible moderator. Design/Methodology/Approach  Participants (N = 183) viewed a web site printout that either did or did not contain a message indicating the organization’s environmental support. Participants rated their attitudes toward the environment, perceptions of the organization, and job pursuit intentions. Findings  Findings demonstrated that the environmental support message positively affected job pursuit intentions; further, this effect was mediated by perceptions of the organization’s reputation. Contrary to the person–organization fit perspective, the message’s effects on job pursuit intentions were not contingent upon the participant’s own environmental stance. Implications  These findings highlight the importance of corporate social performance as a source of information for a variety of job seekers. Even relatively small amounts of information regarding corporate social performance can positively affect an organization’s reputation and recruitment efforts. Originality/Value  In general, this research contributes to the growing body of literature on corporate social responsibility. It is the first study to test whether the effects of pro-environmental recruiting messages on job pursuit intentions depend upon an applicant’s personal environmental stance. In addition, this is the first study to demonstrate reputation’s meditational role in the effects of corporate social responsibility on recruitment efforts.     

Projectible predicates in analogue and simulated systems

We investigate the relationship between two approaches to modeling physical systems. On the first approach, simplifying assumptions are made about the level of detail we choose to represent in a computational simulation with an eye toward tractability. On the second approach simpler, analogue physical systems are considered that have more or less well-defined connections to systems of interest that are themselves too difficult to probe experimentally. Our interest here is in the connections between the artifacts of modeling that appear in these two approaches. We begin by outlining an important respect in which the two are essentially dissimilar and then propose a method whereby overcoming that dissimilarity by hand results in usefully analogous behavior. We claim that progress can be made if we think of artifacts as clues to the projectible predicates proper to the models themselves. Our degree of control over the connection between interesting analogue physical systems and their targets arises from determining the projectible predicates in the analogue system through a combination of theory and experiment. To obtain a similar degree of control over the connection between large-scale, distributed simulations of complex systems and their targets we must similarly determine the projectible predicates of the simulations themselves. In general theory will be too intractable to be of use, and so we advocate an experimental program for determining these predicates.

Ironic effects of explicit gender prejudice on women’s test performance

As prejudice becomes more subtle in its manifestations, members of stigmatized groups must often contend with the ambiguity of not knowing whether others are biased against them. In this study, we tested whether explicitly communicated gender prejudice would facilitate women’s performance on a difficult task compared to contexts where such discrimination might be possible but is not explicitly communicated. The findings revealed that the task performance of women who are chronically concerned about gender discrimination suffered when a male interviewer’s gender attitudes were ambiguous, relative to when his attitudes were either explicitly chauvinistic or explicitly egalitarian. As expected, the performance of women low in discrimination concerns was not affected by the experimental manipulation. The findings are discussed in light of growing evidence for the ironic effects of prejudice for the targets of stigma.     

Sleep, watchkeeping and accidents: a content analysis of incident at sea reports

The unique profession of seafaring involves rest and sleep in a 24-h-a-day work environment that usually involves time-zone crossings, noise, heat, cold and motion. Sleep under such conditions is often difficult to obtain, and sleeping and sleep loss are often related to fatigue and contributory to accidents. This study aims to determine how accident investigators report sleep in Incident at Sea Reports and subsequently analyse the relationships between sleep, fatigue and accidents in these reports.The full text of 44 Incident at Sea Reports was coded and analysed using NUDIST software. This sample included collisions and groundings reported since 1991, where significant human factors contributed to the incident. The Incident at Sea Reports were electronically searched for reference to sleep and content was indexed against parameters such as fatigue behaviours, time of day and contributing personnel. Incident at Sea Reports incorporate three levels of reference to sleep, analysis of which may associate sleeping and sleepiness with accident causation. The highest level of reference unequivocally associates either being asleep, or being sleep deprived with accidents, but not always with fatigue. At an intermediate level, reference to the conflicting pressures of work and sleep on board fishing boats and ships suggests a work environment that is not conducive to obtaining sufficient sleep, and accident investigators are usually unable to link the watchkeeping environment with fatigue as a contributing factor. At the lowest level of association, reference is made to the integrated nature of sleeping and work on board.     

LMX and Subordinate Performance: The Moderating Effects of Task Characteristics

Role conflict, role ambiguity, and intrinsic task satisfaction are found to moderate the relationship between leader–member exchange (LMX) and subordinate performance. Data from a field study of 146 supervisor–subordinate dyads indicate low conflict, high ambiguity, and high intrinsic satisfaction enhance the link between LMX and performance. Neutralizing effects are found when ambiguity and intrinsic satisfaction are low. High conflict appears to have a constraining effect, whereby the connection between LMX and performance is reduced but not neutralized. Results from the study call attention to the theoretical and practical benefits of examining the LMX/performance link from a contingency perspective, and offer a viable, albeit tentative, explanation for inconsistent findings reported in earlier studies.     

Queuing or sharing? A critical evaluation of the single-bottleneck notion

The model of a single central bottleneck for human information processing is critically examined. Most evidence cited in support of the model has been observed within the overlapping tasks paradigm. It is shown here that most findings obtained within that paradigm and that were used to support the model are also consistent with a simple resource model. The most prominent findings are the millisecond-for-millisecond slope at the left of the RT2-SOA curve, the high RT1-RT2 correlation, the additivity of the effects on RT2 of SOA and of the difficulty of selecting R2, and the washout of the effect of S2 discriminability on RT2 in a dual-task condition. In addition, the asymmetry of the effects of the dual-task requirement on RT1 and RT2 can be accounted for by the resource model provided that it assumes uneven allocation of resources, which is quite reasonable in view of the task asymmetry inherent in the demand characteristics of the paradigm. The same is true for two other findings that appear to support the single-bottleneck model-that in the dual-task condition, the demand of the first task affects equally RT1 and RT2 and that its effect on RT1 is the same as the corresponding effect in the single-task condition. Furthermore, the single-bottleneck model is hard to reconcile with a negative slope at the left of the RT1-SOA curve or a positive slope at the left of the IRI-SOA curve, unless augmented by ancillary assumptions that are yet to be substantiated. Representative data were fit by each of the models using its optimal set of parameters. Both models achieved quite good degrees of fit. It is further argued that since the overlapping tasks paradigm is heavily biased in favor of a speedy reaction to the stimulus that appears first, it is nonoptimal for testing the central bottleneck model. Finally, the bottleneck model is examined in terms of other scientific criteria.     

Math Anxiety: Personal, Educational, and Cognitive Consequences

Highly math-anxious individuals are characterized by a strong tendency to avoid math, which ultimately undercuts their math competence and forecloses important career paths. But timed, on-line tests reveal math-anxiety effects on whole-number arithmetic problems (e.g., 46 + 27), whereas achievement tests show no competence differences. Math anxiety disrupts cognitive processing by compromising ongoing activity in working memory. Although the causes of math anxiety are undetermined, some teaching styles are implicated as risk factors. We need research on the origins of math anxiety and on its "signature" in brain activity, to examine both its emotional and its cognitive components.
