Labeling sexual harassment in the military: an extension and replication

Research conducted by V. Magley, C. Hulin, L. F. Fitzgerald, and M. DeNardo (1999) has suggested that women who experience sexual harassment report worse outcomes independent of the labeling process. This study replicates and extends that work. Discriminant analyses were conducted on a sample of approximately 28,000 men and women from the military. The authors included variables similar to those used by V. Magley et al., as well as a variety of antecedent variables. Two significant functions were obtained from the discriminant analysis. The 1st function ordered groups according to the frequency of harassment and accounted for substantially more variance than did the 2nd function, which ordered groups according to whether they labeled their experiences as sexual harassment. The overall results from these analyses demonstrate that labeling incidents as sexual harassment is of marginal meaningfulness in terms of job outcomes and antecedents of harassment.     

Source of improvement in balance control after a training program for ankle proprioception

Previous research on healthy individuals reported improvements in balance control following a purported ankle proprioception-training program. The training may have resulted in a general rather than a specific enhancement of ankle proprioception. To test this hypothesis, subjects were constrained at the hips and trunk with a custom-made thoracolumbosacral orthosis and performed a one-leg standing test with eyes closed and head tilted back, so that they had to rely primarily on their ankle musculature to keep their balance. Subjects were retested after training on the BAPS three times a week for 4 weeks, following the training recommendations of the manual. Subjects' bodies were not constrained during the training. Analysis showed that subjects made improvements during training in performing more difficult tasks on the board. On the one-leg test, however, there were no improvements in sway velocity, number of touchdowns, or falls relative to pretest scores. Improvements observed during training likely resulted from diffuse enhancement of proprioception in other body segments such as the knees, hips, spine, and upper extremities. A training program in control of general balance does not specifically target ankle proprioception.     

Examining the effectiveness of a community-based self-help program to increase women's readiness for smoking cessation

This study investigated the effectiveness of two components of a smoking cessation intervention: a reading manual and a series of televised programs. Female smokers in the Chicago metropolitan area with a high school education or less were interviewed at 4 different times: baseline, immediate postintervention, and 6 and 12 months. We examined the effects of several baseline measures (race, age, number of cigarettes smoked, and stage of readiness to change) and exposure to the intervention components on subsequent stage of change. Race, baseline smoking rate, baseline stage, and exposure to both intervention components had direct effects on stage at immediate postintervention, with both intervention components increasing readiness to quit. Furthermore, exposure to the manual interacted with baseline stage, such that the manual benefited women at earlier stages more than women at later stages. Effects of both components were sustained at 6 months, and the effects of the manual were sustained at 12 months.     

Refutation of Poffenberger's inference: an existence proof and a countermodel

Interhemispheric relay time (IHRT) is inferred from simple (visual) reaction time (SRT) by subtracting SRTs in ipsilateral hand-field conditions from SRTs in contralateral hand-field conditions. This index, the "crossed-uncrossed differential" (CUD) is a synonym of IHRT in the current literature. The CUD has been shown to be significantly moderated by experimental variables, including attentional. One reason the CUD = IHRT hypostasy persists today is that no experimental manipulation has yet been able to generate a significantly negative CUD in a subject manifesting a significant positive CUD in classical conditions. We implemented an experimental manipulation, in SRT, consisting of increasing complexity of the response after the initial key press required at detection. In a very large scale single-case experiment, we found that the CUD thus went from significantly positive in classical SRT to significantly negative in the increased response load condition.     

Pattern of intrusions in verbal recall: comparison of Alzheimer's disease, Parkinson's disease, and frontal lobe dementia

Although some researchers have suggested that intrusions in word list learning are more frequent in Alzheimer's disease, recent studies have shown that this might not be true. In fact, intrusions are common in many neurological degenerative diseases. The goal of the present study was to examine the types of intrusions made by three groups of patients, namely patients with Parkinson's disease (PD), Alzheimer's disease (AD), and dementia with prominent frontal lobe semiology (FD). Although PD patients learned more words (trials 1 to 5 on the RAVLT) than the two other groups, there was no significant difference in the total number of intrusions. However, significant differences between groups were observed for nonrelated intrusions, the proportion of PD patients (15.4%) being lower than the proportion of AD (45.5%) and FD (45.8%) patients with this type of intrusions. No other type of intrusions (same category, recurring, phonemic) significantly differentiated between the three groups. The proactive interference effect (PI), measured as the difference between first recall of list A and list B recall, was stronger in PD than in the two other groups, reflecting the strong positive correlation between total number of words recalled on the RAVLT and severity of the PI effect. Prior list intrusions (intrusions from list A while recalling list B items) were significantly more pronounced in FD than in the two other groups. Finally, free associations (series of intrusions related to one another but not to the target items) were observed almost exclusively in FD patients. These findings illustrate some qualitative differences between various neurological degenerative diseases. They also stress the marked similarities between AD and FD with regards to verbal learning.     

The mind and brain scholar as a hitchhiker in the post-Gutenberg galaxy: publishing at 2000 and beyond

Electronic journal (e-journal) publishing has started to change the ways we think about publishing. However, many scholars and scientists in the mind and brain sciences are still ignorant of the new possibilities and ongoing debates. This paper will provide a summary of the issues involved, give an update of the current discussion, and supply practical information on issues related to e-journal publishing and self-archiving relevant for the mind and brain sciences. Issues such as differences between traditional and e-journal publishing, open archive initiatives, worldwide conventions, quality control, costs involved in e-journal publishing, and copyright questions will be addressed. Practical hints on how to self-archive, how to submit to the e-journal Psycoloquy, how to create an open research archive, and where to find information relevant to e-publishing will be supplied.     

Global cognitive decline in schizophrenia with remission of symptoms?

The relation of symptoms to cognitive dysfunction in schizophrenia is still controversial. This study was aimed (i) at verifying if a homogeneous sample of 10 young treated outpatients in remission from psychotic symptoms displays a characteristic pattern of cognitive dysfunction and (ii) at testing the issue of a general cognitive impairment. The neuropsychological performance of the patients was confronted with a large control group by means of Equivalent Scores, a normative method widely used in Italy, which allows direct, reliable comparison between tests and between patients. We found that our patients, as a group, were affected by a basic activation deficit in attention and by a semantic impairment. These deficits in symptom-free patients could indicate that their brains are in some ways working differently from those of normal controls and that this pattern is not necessarily linked to psychotic symptoms: their neuropsychological impairment might reflect a basic difference in the way of processing information that is always present and is independent of general intellectual decay.     

Imagined and actual limb selection: a test of preference

Imagined and actual motor performance were compared to determine what factor(s) drive limb selection for programming movements in contralateral hemispace. Forty right-handed blindfolded subjects were asked to 'reach' via auditory stimulus for a small object placed at multiple locations in hemispace. Two conditions were included: arms uncrossed and arms crossed. With the uncrossed condition, responses were similar. With arms crossed, subjects had the choice of keeping the limbs crossed, reacting to proximity, or uncrossing the arms to reach ipsilaterally. In this condition subjects 'imagined' that they would maintain the crossedposition and reach with the hand closest to the stimulus in both right and left hemispace. However, during 'actual' reaching, responses differed. For left-field stimuli, participants kept the arms crossed, but in response to right-field stimuli, subjects preferred to uncross the limbs in order to reach with the dominant hand. These findings suggest that while motor dominance is the primary factor in limb choice for action in ipsilateral hemispace, it appears that object proximity drives limb selection for reaching in contralateral hemispace.     

Early suicide following discharge from a psychiatric hospital

Social and clinical risk factors for completed suicide occurring shortly after discharge from a psychiatric hospital were examined in this case-control study. Seventy-seven individuals who received "suicide" or "undetermined death" verdicts at inquest, and who had been previously discharged from psychiatric hospitals in Bradford, U.K., were compared with a control group. A history of deliberate self-harm was significantly associated with early suicides compared with both late suicides and controls. A diagnosis of mood disorder, specifically depression, and longer case-notes were also significantly associated with early suicides compared to controls. This study has implications for risk management of recently discharged psychiatric patients.
