Sociology and psychology within the scope of scientific dishonesty

A survey is undertaken based on qualitative analyses of the cases of scientific misconduct from the Danish Committee on Scientific Dishonesty’s first five years of collecting data, with additional information from selected international sources, in which underlying psychological motivations can be judged. An carlier version of this paper was presented at a symposium, Scientific Misconduct. An International Perspective, organised by The Medical University of Warsay, 16 November, 1998.     

Nature of codes extracted during the attentional blink

This set of 6 experiments used a 2-target rapid serial visual presentation paradigm to address 2 main questions: (a) What is the nature of the code retrieved from nontarget (i.e., unselected) items? and (b) How do the processing demands of the target affect the nature of the codes extracted from its proximate distractors? There were 3 main results: First, unless a nontarget receives attentional processing, its codes remain dormant. The type of activated codes depends on the perceptual load imposed by the other items that also underwent processing. Second, the item trailing the target invariably gets processed, but those farther downstream are excluded. If target selection is exacting, the codes of the item leading the target may also be enhanced. Third, the magnitude of the attentional blink increases with target selection difficulty; it is, however, unaffected by the perceptual load imposed by the target.     

Documentation: The challenges facing Christian‐Muslim dialogue

During his visit to Cairo in early October 1995, Dr George Carey, Archbishop of Canterbury, gave a lecture at Al‐Azhar University, the oldest and one of the most prestigious Islamic universities. Given on 4 October, the lecture was widely reported in both the Egyptian and British press. Following is the full text of the lecture as delivered, reproduced by the kind permission of Dr Carey.     

How reason for surgery and patient weight affect verdicts and perceptions in medical malpractice trials: a comparison of students and jurors

Jurors' decision-making processes are often influenced by extra-legal factors, including judgments of defendants and plaintiffs. Two studies comparing the decisions of university students with those of community jurors sought to determine if extra-legal factors such as individual differences (including identity as a student or juror participant), the reason for surgery (medically necessary vs. elective), the type of surgery (e.g., gastric bypass, nasal reconstruction) or weight of the patient influenced jurors' decisions and perceptions in medical malpractice suits, such that participants would hold negative perceptions of overweight patients or patients who undergo elective surgeries. Results indicate that students and jurors differ in perceptions of the patient's injury and perceptions of risk, which explains some of the variance in liability verdicts. Students were more likely to find doctors liable, but also were more likely to assign responsibility to patients than were jurors. Patients who had undergone elective surgery were seen as more responsible for their situation - and their doctors were assigned less responsibility - than those who had undergone a medically necessary surgery. Tests of weight bias showed that jurors found overweight patients less responsible for their situation than patients of normal weight, but students showed the opposite pattern. Theoretical explanations are explored and implications discussed.     

Contrast polarity preservation's role in perception: explained and unexplained stimuli

Roncato and Casco (2003, Perception & psychophysics 65 1252-1272) had shown that in situations where the Gestalt principle of good continuity is put into conflict with preservation of contrast polarity (CP) the perception that preserves CP prevails. Parlangeli and Roncato (2010, Perception 39 255-259) have studied this question of preservation of CP more closely and have added an addendum to the rule. They have used stimuli consisting of a checkerboard of perpendicularly arranged rectangular bricks (white, gray, or black) and draughtsmen white, gray, or black disks placed at the corners of the bricks. This study has caused them to add an addendum to the rule of CP-preserved path-conjunction binding: if there are two contour completions that preserve the CP, the one with the higher contrast will prevail. Parlangeli and Roncato find that, for certain shades of the disks and bricks, the perpendicular lines of the checkerboard appear strikingly to be slanted or undulating. Here we consider all possible arrangements of relative magnitudes of checkerboards consisting of bricks of two different shades and disks of two shades as well, as such arrangements with widely varying differences in the magnitude of brightness. We have found a number of cases where the perception is not explained by the rule and addendum of Roncato and Casco, and Parlangeli and Roncato, and a case where preservation of "distant" as well as local CP plays a role in perception. The previously known cases, and the new exceptional unexplained stimuli we have found, warrant further study.     

Evolutionary autonomous agents and the naturalization of phenomenology

The phenomenological goal of grounding the content of conceptual thought in the background understanding of everyday, skillful coping was approached using evolutionary autonomous agent (EAA) methodology. The behavior of an EAA evolved to perform a specified motor task was identified with skillful coping. Changes in the dynamics of the EAA controller occurred when the EAA encountered an unexpected obstacle with loss of longer time scale components in its hierarchical temporal organization. These temporal changes are consistent with the phenomenological changes which we experience with breakdown during equipment use with our adoption of a more immediate, determinate stance. Since this latter experience is the basis of conceptual thought, the EAA paradigm goes some way in providing a naturalized explanation for the grounding of the content of conceptual thought in everyday, skillful coping in a manner that is physiologically plausible and phenomenologically accurate.     

Data acquisition software for high data rate experiments

A computerized perceptual laboratory operates a variety of stimulus devices, including static and dynamic graphics displays, and records both discrete and analog data in a diverse and complex set of experimental paradigms. The software requirement to accommodate this variety of paradigms and high input and output data rates has been met by a single multitasked acquisition program that interprets unitary event commands to display graphics or nongraphics stimuli, record responses, control timing, or provide appropriate feedback. Event lists are created and modified with a text editor, then assembled into binary experiment definition files by dialogue with a parsing program. Graphics stimuli are referenced by a file name that contains stimulus attributes for later data extraction. All protocols and stimulus files are loaded prior to the block of trials, so no disk accesses that would delay events are required during a block. The resulting data file contains a record of all variable stimulus and timing information, as well as the discrete and analog responses, in a uniform format which facilitates data extraction.
