Kitchener's Principle Ethics: Implications for Counseling Practice and Research

This extensive literature review examining the influence of K. S. Kitchener's (1984) introduction of principle ethics on counseling and psychology ethics notes the ultimate practicality of principle ethics. The authors maintain that although a strong influence of principle ethics in the area of counselor education emerges through the review, there is little clear evidence of influence in the areas of counseling research or practice. A primary reliance in the counseling professional literature on K. S. Kitchener's original work has likely resulted in a static understanding of the concepts and a concomitant theory–to–application knowledge gap. Implications include a more thorough and ongoing bridging between counseling ethics, philosophical ethics and practice, and a more overt presence of principle ethics.     

The Main Problem with USC Libertarianism

Libertarians like Robert Kane believe that indeterminism is necessaryfor free will. They think this in part because they hold both (1) thatmy being the ultimate cause of at least part of myself is necessary forfree will and (2) that indeterminism is necessary for this ``ultimateself-causation'. But seductive and intuitive as this ``USCLibertarianism' may sound, it is untenable. In the end, nometaphysically coherent (not to mention empirically valid) conception ofultimate self-causation is available. So the basic intuition motivatingthe USC Libertarian is ultimately impossible to fulfill.     

Attention shifts and the Simon effect: a failure to replicate Stoffer (1991)

The Simon effect refers to the intrusion of an irrelevant spatial dimension in the selection of a response to a stimulus. Recently, Stoffer (1991) proposed a specific role for attention orienting in the Simon effect. According to Stoffer, attentional shifts from an initial fixation point to a stimulus location are associated with the generation of a spatial code which specifies the position of the stimulus in relation to the last attended location. This spatial code forms the basis for the Simon effect because it is used to specify the selection of the right or left response. Three experiments were performed to examine further the attention-shift hypothesis forwarded by Stoffer. Experiment 1 was an attempt to replicate Stoffer (1991), but failed to do so. Experiments 2 and 3 were designed to optimize conditions for replicating crucial aspects of Stoffer's findings, but also failed to yield support for the attention-shift account.     

Spatiotopic and retinotopic components of iconic memory

Summary Recently, there has been considerable interest in whether information in iconic memory is stored in retinotopic or spatiotopic coordinates. The present experiment examined the issue using a masking paradigm. In one set of conditions, subjects maintained fixation while a row of four letters appeared for 19 ms, centered about three degrees to the right of fixation. After a 153 ms ISI, the letters were followed by a blank field (no mask), a mask in the same position as the letters, or a mask displaced three degrees to the right of the letters. In a second set of conditions, the stimuli were the same but subjects were asked to shift fixation from the fixation point to the middle of the letter row during the interval between the letters and the mask. Subjects' eye movements were monitored in all conditions. Accuracy of report for the letters was lowered only with the mask over the letters with the no-eye-movement conditions and in both masking conditions with the eye movements. The results suggest that the icon includes two components, one that is retinotopic and one that is spatiotopic.     

The validity of a computerized visual searching task as an indicator of brain damage

Goldstein, Rennick, Welch, and Shelly (1973) developed a visual searching task (VST) that succeeded in obtaining a hit rate of 94.1% correct classifications when comparing brain-damaged and normal subjects and a 79.4% hit rate when comparing brain-damaged and psychiatric subjects. Goldstein and Kyc (1978) reported 92.5% correct classifications for the brain-damaged vs. normal comparisons and 82.5% correct classifications for brain-damaged vs. schizophrenic comparisons. We computerized the administration of the VST and found 85.7% correct classifications for the brain-damaged vs. normal groups and 71.4% correct classifications for the brain-damaged vs. psychiatric group. These results suggest that the computerized VST (CVST) is also a potentially valid indicator of brain damage.
