Attitudes Toward Industrial Pollution, Strategies for Protecting the Environment, and Environmental-Economic Trade-offs

Attitudes toward industrial pollution, environmental-economic trade-offs, and endorsement of various strategies and activities to protect the environment were examined in a community sample. Environmental attitudes were measured using seven distinct factors organized around four cognitive themes: commercialist-expansionist-emphasizing industrial concerns even at the expense of environmental considerations; reformist-emphasizing the need and possibility of environmental quality; radical-emphasizing pessimism over the possibility of environmental quality, given the present economic and policital system; and finally, denial that the community has been harmed by pollution. Examination of the relationship between pollution attitudes and endorsement of the various proenvironmental activities yielded a pattern consistent with a cognitive, syllogistic model of the organization of attitudes. Those emphasizing a commercialist position neither favored nor regarded the various environmental activities as effective. Those who emphasized reform endorsed the various activities as both favorable and effective. Denial was associated with opposition to the various activities. Finally, those taking a radical position favored the various strategies but were not convinced of their efficacy.     

Personality and belief in Capital Punishment: a replication and extension

Male and female Canadian undergraduates identified as high or low on Extraversion and Psychoticism on the basis of the Eysenck Personality Questionnaire completed the Questionnaire on Capital Punishment. In a replication of a previous study, males and extraverts reported more favourable attitudes towards Capital Punishment than females and introverts. In contrast, there were no significant differences in attitude between subjects classified as high and low on Psychoticism, a result which may be due to the difficulty of finding normal subjects with absolutely high scores on this trait.     

Sinusoidal plucks and bows are not categorically perceived,either

Cutting and Rosner (Perception & Psychophysics, 1974,16, 564–570) reported that two acoustic nonspeech continua varying in rise time were categorically perceived. We have already shown (Rosen & Howell,Perception & Psychophysics, 1981,30, 156–168) that the reason their sawtooth continuum was perceived in such a way, and in particular why it exhibited a midcontinuum peak in the discrimination function, was entirely due to the stimuli not having the intended rise times. The other nonspeech continuum that varied in rise time and was reported to be categorically perceived used a sinusoidal carrier. Although the labeling functions obtained were not as sharp as those obtained with sawtooth stimuli, the characteristic midcontinuum discrimination peak was found. We generated such a set of sinusoidal stimuli and found no evidence of categorical perception. Just as we have previously found for sawtooth stimuli, discrimination is best at the short rise-time end of the continuum and decreases monotonically with increasing rise time.     

Mellor and Dennett on the Perception of Temporal Order

I discuss theories about the way in which we determine the precedence ofperceived events. I examine Mellor's account, which claims that it is thetiming of our perceptions of events that enables us to determine their order,and Dennett's criticism of this. Dennett cites psychological experimentswhich suggest that it is the content of our perceptions, rather than theirtiming, which allows us to determine the order of the events perceived. Iargue that by distinguishing between two different ways of construing'perception' we can see not only that the two accounts are compatible, but that Dennett's account presupposes Mellor's.     

The effect of memory load on negative priming: An individual differences investigation

The effect of a verbal (Experiment 1) and a nonverbal (Experiment 2) memory load on negative priming was investigated by employing a concurrent memory task with a letter naming task. Across both experiments, negative priming was reliable only under conditions of zero memory load, suggesting that the processes that contribute to negative priming are resource demanding and dependent on a domain-free resource pool. Individual differences in negative priming were observed, such that high working memory capacity subjects showed reliable negative priming whereas low working memory capacity subjects did not. The results suggest that the negative priming effect results from allocation of controlled attention and that individual differences in working memory capacity correspond to the ability to efficiently handle irrelevant information.     

The effect of prior experience on recognition thresholds for plane-disoriented pictures of familiar objects

We investigated plane rotation effects on the minimum presentation duration that is required in order to recognize pictures of familiar objects, using the method of ascending limits. Subjects made unspeeded verification responses, selecting from 126 written alternatives. Replicating similar identification studies in which brief, masked pictures (Lawson & Jolicoeur, 1998) were presented, disorientation reduced the efficiency of recognition. Mirroring the findings in speeded picture naming studies (e.g., Jolicoeur, 1985; Jolicoeur & Milliken, 1989), but in contrast to those of Lawson and Jolicoeur (1998), orientation effects were found over a wide range of views and were attenuated but not eliminated with experience with a given object. The results bridge the findings from unspeeded verification and speeded naming tasks. They suggest that the same orientation-sensitive processes are tapped in both cases, and that practice effects on these processes are object specific.     

Effects of physical fatigue and cognitive challenges on the potential for low back injury

There is no question that the motor control system will adapt under fatiguing conditions; however, there is documented evidence showing that when fatigued or challenged, the motor control system will, on occasion, perform inappropriate muscle sequencing, increasing the risk of injury, or directly causing injury. Knowing that inappropriate muscle activations can lead to injury, the purpose of this study was to investigate motor patterns during cognitive and physical challenges. Rather than ensure change with severe challenges, milder challenges were purposefully chosen. Eight male subjects performed a low external load task performed near end ROM while in an unchallenged state, and while in three challenged states: passive tissue creep, muscle fatigue and cognitive distraction. Data were collected using EMG of the trunk muscles and angular displacement of the lumbar spine. Comparison of motor control patterns between the unchallenged state and each of the three challenged conditions showed no systematic differences. However, several random anomalies were observed. A case study of a single subject was chosen to show inappropriate motor control during one trial under the cognitive distraction conditions. The response of the motor control system is very individualized and does on occasion produce inappropriate motor patterns. This supports the notion that injury may also occur as the result of random motor control errors as well as predictable, systematic changes.     

A Psychoanalytic Dialectical Model for Sexual and Other Forms of Workplace Harassment

Beginning with a brief literature review, the present paper outlines a dialectical model for sexual and other forms of workplace harassment in which the role dependent models of bully, victim and bystander are seen to complexly interact and facilitate each other. An organization which has a bully always has the other two roles represented according to the model. It is suggested that for a workplace to function harmoniously all three roles must be addressed, and the power struggle resolved. The theory is illustrated with a series of case studies drawn from a forensic psychiatry practice. These include some more unusual forms of harassment such as the harassment of a Mexican American woman by an African American woman, the harassment of a middle-aged conservative man by two young women, the harassment of a man by several male employees together with traditional patterns of an older male employer harassing a younger female employee. Psychoanalytic processes which explain the pathological patterns are illustrated with material drawn from a psychoanalysis of a harassed woman. The paper concludes with some brief suggestions for a plan for workplace intervention.
