“Sherry’s Secret”

The case and commentaries below were developed as part of a project, Graduate Research Ethics Education, undertaken by the Association for Practical and Professional Ethics with funding from the National Science Foundation (NSF Grant No. SBR 9421897 and NSF Grant No. 9817880). The project aims at training graduate students in research ethics and building a community of scientists and engineers who are interested in and capable of teaching research ethics. As part of the project, each graduate student participant develops a case for use in teaching and writes a commentary to go with the case, and then a staff member is asked to write additional commentary on the case. The case below was written in the second year of the project and was published in Research Ethics: Cases and Commentaries edited by B. Schrag, Association for Practical and Professional Ethics, Bloomington, Indiana, Vol. II (1998). Publication of these cases and commentaries will be a recurring feature of Science and Engineering Ethics.     

Increasing Communication Among Nursing Home Residents

In this preliminary, intrasubject study (N = 8), we examined the effects of communication skills training and the use of memory books by Nursing Assistants (NAs) on the social ecology of a nursing home. Through inservice and on-the-job training, NAs were taught to use communication skills and memory books during their interactions with residents with mild to moderate cognitive impairment (Mini Mental Status Examination, M = 16.25), but relatively intact communication abilities. An abbreviated staff motivational system called Behavioral Supervision (Burgio and Burgio, 1990. Int. J. Aging Hum. Deve. 30: 287–302.) was attempted to encourage performance of these skills on the nursing units. Results showed that, regardless of sporadic implementation of the intervention by nursing staff, the intervention improved communication between staff and residents during care routines, increased the amount of time other residents and visitors spent talking with target residents, and increased the rate of positive statements made by the target residents and others in their immediate environment. Results are discussed in terms of limitations of the staff motivational system and modifications made to the system in a larger ongoing intervention trial.     

Constraints on nest site selection: a comparison of predator and flood avoidance in four species of marsh-nesting birds (genera: Catoptrophorus, Larus, Rallus, and Sterna)

Nest site characteristics associated with flood and predator avoidance were compared for four nonpasserine species of marsh-nesting birds: clapper rails, willets, laughing gulls, and common terns. Species with short nests, willets and terns, minimized flood damage by nesting on higher ground than did gulls and rails that build tall nests. Species with dispersed, cryptic nests had taller surrounding grass than did open-nesting colonial species. Total nest height was similar for species with tall nests and for terns whose short nests were elevated by placement on mats of dead Spartina grass. Willets had lower nest heights than the other species, probably because the inverse relation between grass height and ground height in the salt marsh makes it difficult for willets to find sites with high enough ground for flood avoidance while still retaining high enough grass for nest crypticity. Ground height for common terns and grass height for gulls and rails appear to be cues used in nest site selection. Nests of each species in which these characteristics were maximized were more successful in a major tidal flood. Laughing gulls and clapper rails appear to be more specialized salt marsh nesters than the other two species.     

Cholinergic blockade, septal lesions, and DRL performance in the rat.

Four experiments describing the effects of cholinergic blockade produced by systemic injection of either atropine sulfate or atropine methyl nitrate on the differential reinforcement of low rate (DRL) responding of rats are reported. It was shown that atropine sulfate injected either chronically or at high dosage suppressed DRL responding. Injected acutely, atropine sulfate produced disinhibitory effects. When atropine was injected either chronically or acutely into animals with septal lesions, there was suppression of responding. It was suggested that the specific behavioral outcome resulting from cholinergic blockade depends on the balance resulting from the competing peripheral and central effects of such blockade.     

Individual differences in mental animation during mechanical reasoning

In three experiments we tested the effects of spatial visualization ability on performance of a motion-verification task, in which subjects were shown a diagram of a mechanical system and were asked to verify a sentence stating the motion of one of the system components. We propose that this task involves component processes of (1) sentence comprehension, (2) diagram comprehension, (3) text-diagram integration, and (4) mental animation. Subjects with law spatial ability made more errors than did subjects with high spatial ability on this task, and they made more errors on items in which more system components had to be animated to solve the problem. In contrast, the high-spatial subjects were relatively accurate on all trials. These results indicate that spatial visualization is correlated with accuracy on the motion-verification task and suggest that this correlation is primarily due to the mental animation component of the task. Reaction time and eye-fixation data revealed no differences in how the high- and low-spatial subjects decomposed the task. The data of the two groups of subjects were equally consistent with a piecemeal model of mental animation, in which components are animated one by one in order of the causal chain of events in the system.     

When to intervene and take a stand: Evaluating bystander roles in intergroup name-calling contexts

Children (n = 121, M = 9.86 years, SD = 0.64) and adolescents (n = 101, M = 12.84 years, SD = 0.69) evaluated proactive and passive bystander behaviour to intergroup name-calling (N = 222, 54% female). Scenarios depicted ingroup perpetrators and outgroup victims who were from a stigmatized group (ethnicity) or a non-stigmatized group (school affiliation), with bystanders depicted as being proactive (intervening to help) or passive (failing to challenge the aggression), counter to their own group's norm. Children and adolescents personally evaluated proactive bystanders more favourably than passive bystanders. However, adolescents, more than children, expected their peers to be more positive about proactive bystanders than passive bystanders in the stigmatized context. Results are discussed in terms of the complexities of bystander decisions and implications for anti-bullying interventions.     

After the New Age

This article explores the connections between conventional religion and the New Age, using data from a major online questionnaire study, Survey2001 , that was sponsored by the National Geographic Society and the National Science Foundation. It begins with two competing hypotheses. (1) Involvement in conventional religion discourages involvement in unconventional para-religion because conventional religion competes with para-religion. (2) Conventional religion encourages unconventional para-religion by promulgating supernatural assumptions about the nature of humanity and the universe. Factor analysis of 20 putatively New Age agree-disagree questionnaire items reveals that 15 of them define a general New Age factor, supported by secondary anti-paranormal and anti-alien factors. Three measures of conventional religiousness show complex relations to the New Age items. Analysis using factor scores indicates that both hypotheses express real effects that cancel each other out for many people. Individual subjective religiousness and personal prayer or meditation correlate strongly positively with the New Age among respondents who never attend religious services. The study considers denominational differences, then concludes by showing that a curvilinear relationship exists between religiousness and acceptance of New Age beliefs.     

Differential relationship of recent self-reported stress and acute anxiety with divided attention performance

There have been relatively few studies on the relationship between recent perceived environmental stress and cognitive performance, and the existing studies do not control for state anxiety during the cognitive testing. The current study addressed this need by examining recent self-reported environmental stress and divided attention performance, while controlling for state anxiety. Fifty-four university undergraduates who self-reported a wide range of perceived recent stress (10-item perceived stress scale) completed both single and dual (simultaneous auditory and visual stimuli) continuous performance tests. Partial correlation analysis showed a statistically significant positive correlation between perceived stress and the auditory omission errors from the dual condition, after controlling for state anxiety and auditory omission errors from the single condition (r = 0.41). This suggests that increased environmental stress relates to decreased divided attention performance in auditory vigilance. In contrast, an increase in state anxiety (controlling for perceived stress) was related to a decrease in auditory omission errors from the dual condition (r = - 0.37), which suggests that state anxiety may improve divided attention performance. Results suggest that further examination of the neurobiological consequences of environmental stress on divided attention and other executive functioning tasks is needed.
