How research ethics boards are undermining survey research on Canadian university students

In Canada, all research conducted by individuals associated with universities must be subjected to review by research ethics boards (REB). Unfortunately, decisions reached by REBs may seriously compromise the integrity of university-based research. In this paper attention will focus on how requirements of REBs and a legal department in four Canadian universities affected response rates to a survey of domestic and international students. It will be shown that in universities in which students were sent a legalistic cover letter to a mail survey, or were required to sign a consent form, lower response rates were achieved than in universities in which students were sent a relatively friendly letter. In turn, lower response rates resulted in: sample characteristics that deviated from population characteristics; a reduction in the possibility of testing research hypotheses; and increased survey costs. As a consequence, it is argued that the unreasonable demands of REBs are seriously compromising the quality of research that can be carried out on Canadian university students.

Dynamic shifts of pigeon local/global attention

It has previously been shown that pigeons can shift attention between parts and wholes of complex stimuli composed of larger, "global" characters constructed from smaller, "local" characters. The base-rate procedure used biased target level within any condition at either the local or global level; targets were more likely at one level than at the other. Biasing of target level in this manner demonstrated shifts of local/global attention over a time span consisting of several days with a fixed base rate. Experiment 1 examined the possibility that pigeons can shift attention between local and global levels of perceptual analysis in seconds rather than days. The experiment used priming cues the color of which predicted on a trial-by-trial basis targets at different perceptual levels. The results confirmed that pigeons, like humans, can display highly dynamic stimulus-driven shifts of local/global attention. Experiment 2 changed spatial relations between features of priming cues and features of targets within a task otherwise similar to that used in experiment 1. It was predicted that this change in cues might affect asymmetry but not the occurrence of a priming effect. A priming effect was again obtained, thereby providing generality to the claim that pigeons can learn that trial-by-trial primes predict targets at different levels of perceptual analysis. Pigeons can display perceptual, stimulus-driven priming of a highly dynamic nature. Electronic Publication     

Integration of spatial maps in pigeons

The integration of spatial maps in pigeons was investigated using a spatial analog to sensory preconditioning. The pigeons were tested in an open-field arena in which they had to locate hidden food among a 4×4 grid of gravel-filled cups. In phase 1, the pigeons were exposed to a consistent spatial relationship (vector) between landmark L (a red L-shaped block of wood), landmark T (a blue T-shaped block of wood) and the hidden food goal. In phase 2, the pigeons were then exposed to landmark T with a different spatial vector to the hidden food goal. Following phase 2, pigeons were tested with trials on which they were presented with only landmark L to examine the potential integration of the phase 1 and 2 vectors via their shared common elements. When these test trials were preceded by phase 1 and phase 2 reminder trials, pigeons searched for the goal most often at a location consistent with their integration of the LT phase 1 and Tphase 2 goal vectors. This result indicates that integration of spatial vectors acquired during phases 1 and 2 allowed the pigeons to compute a novel Lgoal vector. This suggests that spatial maps may be enlarged by successively integrating additional spatial information through the linkage of common elements.     

Visually guided capture of a moving stimulus by the pigeon (Columba livia)

Although the pigeon is a popular model for studying visual perception, relatively little is known about its perception of motion. Three experiments examined the pigeons’ ability to capture a moving stimulus. In Experiment 1, the effect of manipulating stimulus speed and the length of the stimulus was examined using a simple rightward linear motion. This revealed a clear effect of length on capture and speed on errors. Errors were mostly anticipatory and there appeared to be two processes contributing to response locations: anticipatory peck bias and lag time. Using the same birds as Experiment 1, Experiment 2 assessed transfer of tracking and capture to novel linear motions. The birds were able to capture other motion directions, but they displayed a strong rightward peck bias, indicating that they had learned to peck to the right of the stimulus in Experiment 1. Experiment 3 used the same task as Experiment 2 but with naïve birds. These birds did not show the rightward bias in pecking and instead pecked more evenly around the stimulus. The combined results indicate that the pigeon can engage in anticipatory tracking and capture of a moving stimulus, and that motion properties and training experience influence capture.

Pigeons (Columba livia) plan future moves on computerized maze tasks

Planning, the internal process of formulating an organized method about one's future behavior, should be advantageous for non-human animals as well as for humans. However, little is known about this process in avian species. We examined planning processes in pigeons (Columba livia) using a computerized maze task. In Experiment 1, we found that the pigeons plan their next one step, and in some cases even correctly adjust their actions after change of goal locations, while performing on a plus-shaped maze. We also showed that the pigeons might even plan two steps on familiar, well-practiced mazes. In Experiment 2, we discovered that the subjects plan the direction they would go first before starting to solve a four-arm shuriken (a Japanese traditional throwing knife)-shaped maze. The birds also corrected their previously planned actions after change of goal locations. Our results from these experiments suggest that planning ahead is within the cognitive capacity of a "bird brain", and that it may be more widespread in the animal kingdom than has been presumed.     

Time-space learning in homing pigeons (<Emphasis Type="Italic">Columba livia</Emphasis>): orientation to an artificial light source

Time-space learning reflects an ability to represent in memory event-stimulus properties together with the place and time of the event; a capacity well developed in birds. Homing pigeons were trained in an indoor octagonal arena to locate one food goal in the morning and a different food goal in the late afternoon. The goals differed with respect to their angular/directional relationship to an artificial light source located outside the arena. Further, the angular difference in reward position approximated the displacement of the sun's azimuth that would occur during the same time period. The experimental birds quickly learned the task, demonstrating the apparent ease with which birds can adopt an artificial light source to discriminate among alternative spatial responses at different times of the day. However, a novel midday probe session following successful learning revealed that the light source was interpreted as a stable landmark and not as a surrogate sun that would support compass orientation. Probe sessions following a phase shift of the light–dark cycle revealed that the mechanism employed to make the temporal discrimination was prevailingly based on an endogenous circadian rhythm and not an interval timing mechanism.     

HOW THE PHILOSOPHY OF SCIENCE CHANGED RELIGION AT NINETEENTH‐CENTURY HARVARD

Nineteenth‐century Harvard faculty and students looked to philosophical ideas about the proper and effective study of nature as the model of rationality to which their religion must conform. As these ideas changed, notions of rationality changed and so did Harvard religion.     

The relationship between self-report and lab task conceptualizations of impulsivity

Research has yet to examine the overlap among the different aspects of impulsivity that has been suggested by self-report and behavioral lab task measures. The aim of the current study is to conduct the first comprehensive empirical study including all previously identified aspects of impulsive action in order to examine the construct overlap of both lab task and self-report conceptualizations of impulsivity. Participants were 77 undergraduate students (54 female) in an introductory psychology course. Results suggest that self-report and behavioral lab tasks are assessing discrete aspects of impulsivity. The current study provides estimates of effect sizes and can inform future research hypotheses concerning the overlap between self-report and lab task impulsivity domains.     

Group mentoring to foster the responsible conduct of research

This article reports on a method of group mentoring to strengthen responsible research conduct. A key feature of this approach is joint exploration of the issues by trainees and their faculty research supervisors. These interactions not only help participants learn about current ethical norms for research practice, but also draw on the accumulated experience of faculty and staff about practical problems of research conduct, and help to make faculty more articulate about responsible research conduct and so better able to guide their trainees. By working with departments or laboratories as a whole the method facilitates the formulation of specific norms appropriate to particular research situations and to strengthen the group’s ability to support appropriate behavior and deal with new issues as they arise. It also gives students more ways to ask questions about research practice and to benefit from the experience of all members of their department or group as well as their own research supervisors. The method is well tested and has been well received by a wide variety of departments and research groups. It provides the means for a constructive and enjoyable response to the Public Health Service’s (PHS) new Policy on Instruction in the Responsible Conduct of Research (RCR) that requires education in the responsible conduct of research for all those funded by PHS funds, including faculty and staff as well as trainees. An earlier version of this paper was presented at a National Science Foundation sponsored conference on Mentoring and Research Values: Students as Vital Human Resources, Chicago, IL, USA, March 1995.     

The four P’s of purpose among College Bound students: People,propensity, passion,prosocial benefits

Abstract

College preparation programs, such as College Bound, aim to increase low-income students’ preparation for achieving future goals. Yet, little research has examined the nature of these students’ future goals and purposes from their own perspectives. In this study, in-depth interviews with 10 adolescents (six males and four females) participating in College Bound were analyzed using a qualitative approach informed by grounded theory. Four interrelated themes related to the development of youth purpose emerged: (a) people; (b) propensity; (c) passion; and (d) prosocial benefits. These themes were further categorized across two major dimensions: influences (i.e. capability and motivation) and sources of such influences (i.e. intrinsic and extrinsic). Moreover, ways in which students’ unique social contexts contributed to their experiences of purpose are discussed. Findings inform an understanding of the development of purpose in underrepresented youth, as well as provide insights for programs designed to promote their positive development and post-secondary school success.
