The MEL Library in the undergraduate research methods course

The MEL Library is a teaching tool for the undergraduate research methods course, designed to teach content and methodology, with additional practical experience in experimental design, graphic presentation of data, and integration of experimental results within the framework of an evolving science of psychology. A set of exercises replicates many classic experiments in psychology. Students can run these experiments using themselves as subjects. Data then can be merged across subjects, and statistical analyses of the group data can be performed. In addition, easy implementation of changes in the experiments permits students to explore beyond the set exercises, allowing them to develop their own research ideas for semester projects or honors theses.     

CONTEXTUALIZING VIOLENCE IN A PARTICIPATORY CLASSROOM

Techniques for integrating race, class, gender, sexual orientation, age, disability, and other categories of socially defined identity in a student-centered participatory classroom are outlined for a survey course on women and violence. Keeping categories of socially defined identity central to every course component changes not only the content of the course, but also the questions asked and the range of possible answers. Students were given two tools with which to analyze each topic: theoretical frameworks (psychology, sociology, feminism) and the categories of socially defined identity. Difficulties with the material are interpreted as signposts of the complexity of the theoretical issues involved rather than as intellectual failures of the students or the instructor. An open and participatory classroom climate facilitates dealing with the stresses of this topic as well as with the ambiguities faced by students exploring the multidimensional space of socially defined identities.     

STEP—A System for Teaching Experimental Psychology using E-Prime

Students in psychology need to learn to design and analyze their own experiments. However, software that allows students to build experiments on their own has been limited in a variety of ways. The shipping of the first full release of the E-Prime system later this year will open up a new opportunity for addressing this problem. Because E-Prime promises to become the standard for building experiments in psychology, it is now possible to construct a Web-based resource that uses E-Prime as the delivery engine for a wide variety of instructional materials. This new system, funded by the National Science Foundation, is called STEP (System for the Teaching of Experimental Psychology). The goal of the STEP Project is to provide instructional materials that will facilitate the use of E-Prime in various learning contexts. We are now compiling a large set of classic experiments implemented in E-Prime and available over the Internet from http://step.psy.cmu.edu. The Web site also distributes instructional materials for building courses in experimental psychology based on E-Prime.     

MacLab: A Macintosh system for psychology labs

MacLab, a program that turns the Apple Macintosh into a psychology laboratory tool, is described. MacLab combines intelligent editors, a millisecond timer, MacPaint pictures, and the ease of use of the Macintosh user interface to create a system with which experimental psychologists can quickly create and run powerful experiments with no need of any knowledge of programming.     

Students' Views on the Value of Psychological Research: A Contribution to Indigenising Psychology in Botswana

The goal of the study was to explore the value that psychology students accredit to psychological research in a country like Botswana where psychology is a relatively new discipline. Forty-five undergraduate students belonging to the first cohort of psychology students at the University of Botswana participated in the study (males = 7, females = 38, age range 18–23 years). Data were obtained from student essays and evaluated with Qualitative Content Analysis. Students were of the view that psychological research should (a) increase knowledge to better understand human beings and the world (epistemological value); (b) create awareness about psychology within society so as to to assist society in combating societal problems (societal value); (c) enhance individuals' understanding of psychology so as to to accept psychology (individual value); and (d) up-date psychological theories to ensure their applicability in present times (theoretical value). Considering students' views could play an important role in indigenising psychology in Botswana.     

Utah Virtual Lab: JAVA interactivity for teaching science and statistics on line

The Utah on-line Virtual Lab is a JAVA program run dynamically off a database. It is embedded in Stat-Center (www.psych.utah.edu/learn/statsampler.html), an on-line collection of tools and text for teaching and learning statistics. Instructors author a statistical virtual reality that simulates theories and data in a specific research focus area by defining independent, predictor, and dependent variables and the relations among them. Students work in an on-line virtual environment to discover the principles of this simulated reality: They go to a library, read theoretical overviews and scientific puzzles, and then go to a lab, design a study, collect and analyze data, and write a report. Each student’s design and data analysis decisions are computer-graded and recorded in a database; the written research report can be read by the instructor or by other students in peer groups simulating scientific conventions.     

Dialogue as Constructivist Pedagogy: Probing the Minds of Psychology's Greatest Contributors

In this article, I report on my use of dialogue as an exploratory teaching tool in an undergraduate colloquium titled Historical Foundations of Psychology. Students completed written assignments in which they identified the contributors to psychology associated with each of a series of position statements that capture the intellectual, philosophical, or theoretical views of these individuals. Students were not told in advance the identity of contributors relative to their respective position statements, which assumed the form of excerpts and quotations (direct or paraphrased) from original and secondary sources. As part of their written responses, students provided supporting rationale for their answers and discussed the truths and misconceptions inherent in each statement. Afterward, students engaged in class discussion involving peer critique of their written responses. Through qualitative assessment, the dialogue method was shown to advance critical thinking and participation in the learning process. Students generally described dialogue as challenging, helpful, and enjoyable in exploring the views of eminent thinkers throughout the history of psychology. Findings are discussed in light of constructivist pedagogy, in which students actively and interactively create their own conceptual understandings. In line with the conclusion that dialogue is a promising instructional technique, future classroom applications are also presented.     

Can Psychology Ethics Effectively Be Integrated into Introductory Psychology?

This study evaluated the integration of psychology ethics into an introductory psychology course. Students in two general psychology sections were exposed to an infusion of psychology ethics in teaching, research, and clinical practice, whereas students in two sections were exposed to traditional course content. Students completed a pre and post-test assessment including a psychology ethics questionnaire and open-ended responses to three ethics case studies. Students in the ethics group displayed a statistically significant increase in scores on both measures from pre to post-test. However, students in the traditional group showed no improvement in scores.     

Student MEL software support for instructors and teaching assistants in research methods course

A number of common problems plague the teaching of the undergraduate research methods course, from the training of teaching assistants to providing meaningful experimental materials to handling data acquisition and analysis. The Student Micro Experimental Laboratory (MEL) offers a systematic approach to the management of a computerized research methods laboratory course by combining high-quality experiments in many areas of psychology with background materials to help the instructor and teaching assistant. The software presents and collects data from 28 experiments. The data can be analyzed for single subjects and for classes as a whole. Students can rapidly implement new experiments in a variety of paradigms. An expanding library of experiments created by students and instructors should provide an expanding environment for teaching experimental research methods. Instructor’s materials provide background information, discussion questions, and data analysis for all experiments. The student workbook provides discussion of the background of the experiment, details of the methodology, and questions addressing various aspects of experimental design and interpretation of data.     

ATTITUDES TOWARD THE USE OF ANIMALS IN PSYCHOLOGICAL RESEARCH AND EDUCATION:

Abstract— This article reports the results of a national survey in which psychology majors were asked about the use of animals in psychological research and teaching. In general, the attitudes of psychology majors closely resembled the attitudes of practicing psychologists. Students tended to (a) support animal experiments involving observation or confinement, but disapprove of studies involving pain or death, (b) support mandatory pain assessments and the federal protection of rats, mice, pigeons, and reptiles, and (c) support the use of animals in teaching, but oppose an animal laboratory requirement for the psychology major. Opposition to the use of animals was greatest among women, among students at selective schools, and among students living in the Northeast/Mid-Atlantic region of the country.     

Using SMS text messaging for teaching and data collection in the behavioral sciences

Recent interest in university teaching has focused on interactivity in lectures and practical classes, and teachers in several fields have set up systems in which students can interact with the lecturer using mobile-phonebased SMS text messaging. This approach has particular potential in psychology, where students could use SMS messaging as a way of responding in simple psychology experiments or demonstrations. We describe a simple architecture for an SMS-based responding, using an SMS-to-HTTP message relay service, and a PHP/MySQL input-output handler. We describe briefly two experiments we have run using the system. The first experiment examined anchoring effects in an SMS-based auction. The second experiment examined delay discounting, with participants indicating their intertemporal preferences using SMS. Finally, we evaluate the feedback we obtained from students about the practical and conceptual issues surrounding text-message-based responding.     

Psychology Experiment Authoring Kit (PEAK): Formal usability testing of an easy-to-use method for creating computerized experiments

In academic courses in which one task for the students is to understand empirical methodology and the nature of scientific inquiry, the ability of students to create and implement their own experiments allows them to take intellectual ownership of, and greatly facilitates, the learning process. The Psychology Experiment Authoring Kit (PEAK) is a novel spreadsheet-based interface allowing students and researchers with rudimentary spreadsheet skills to create cognitive and cognitive neuroscience experiments in minutes. Students fill in a spreadsheet listing of independent variables and stimuli, insert columns that represent experimental objects such as slides (presenting text, pictures, and sounds) and feedback displays to create complete experiments, all within a single spreadsheet. The application then executes experiments with centisecond precision. Formal usability testing was done in two stages: (1) detailed coding of 10 individual subjects in one-on-one experimenter/subject videotaped sessions and (2) classroom testing of 64 undergraduates. In both individual and classroom testing, the students learned to effectively use PEAK within 2 h, and were able to create a lexical decision experiment in under 10 min. Findings from the individual testing in Stage 1 resulted in significant changes to documentation and training materials and identification of bugs to be corrected. Stage 2 testing identified additional bugs to be corrected and new features to be considered to facilitate student understanding of the experiment model. Such testing will improve the approach with each semester. The students were typically able to create their own projects in 2 h.     

The effect of previous experience on preference of approach for effective counseling

Students in a general psychology class viewed four videotapes of initial vocational-educational and initial personal concern counseling sessions. The sessions were presented from a client-centered approach and from a behavioral approach, and employed the same client and counselor. After viewing the tapes, the students were asked to indicate which approach they thought would be more effective in helping a client. Results showed that students who had previously experienced counseling preferred a behavioral approach for both the vocational-educational concern and the personal concern. Students with no experience of counseling did not exhibit a preference.

A laboratory in experimental psychology using the TRS-80

Twenty-three BASIC language programs have been written to allow the TRS-80 and other microcomputers to perform most of the classical experiments normally used in teaching a laboratory course in experimental psychology. Most programs allow experiments to be run as though the computer was the specialized apparatus normally used. This facilitates a realistic and interactive learning experience for the students.     

Questioning as an instructional method: Does it affect learning from lectures?

What can be done to improve student engagement and learning in college lectures? One approach is to ask questions that students answer during the lecture. In two lab experiments, students received a 25‐slide PowerPoint lecture in educational psychology that included four inserted multiple‐choice questions (questioning group) or four corresponding statements (control group). Students in the questioning group used a personal response system (PRS), in which they responded to questions using a hand‐held remote control, saw a graph displaying the percentage of students voting for each answer, and heard the teacher provide an explanation for the correct answer. Students in the control group received the corresponding slide as a statement and heard the teacher provide an explanation. The questioning group outperformed the control group on a retention test in Experiment 1 (d = 1.23) and on a transfer test in Experiment 2 (d = 0.74), but not on other tests. The results are consistent with a generative theory of learning, and encourage the appropriate use of questioning as an instructional method. Copyright © 2008 John Wiley & Sons, Ltd.     

Increasing student interest by the use of interactive computer simulations

Two methods of increasing the involvement of introductory social psychology students with the topic of “person perception” were implemented and compared. Students either experienced two computer simulations of situations which illustrated person-perception principles or participated in a typical person-perception experiment. Students with computer experience, perhaps because of the individualized nature of the simulations, rated “person perception” as more interesting and more important than the experiment-participation students. Knowledge concerning person perception did not differ between groups.     

Working memory limitation as a source of confusion in the abstract THOG task

Limitations of working memory are proposed as a major determinant of problem difficulty in the THOG task. This task is a logical reasoning task which uses an exclusive disjunction and requires hypothetico-deductive reasoning. Four experiments with students of mathematics or psychology were used to test the hypotheses that, first, guiding participants' attention facilitates the task and, second, the use of paper and pencil as external problem representation reliefs working memory load. Focusing participants' attention upon a critical aspect of the task does not improve solution rates. Students of mathematics were better than students of psychology, but only if they were allowed to use paper and pencil or to work on the task repeatedly. These results partially support the working memory hypothesis. They point toward the importance of training and practice in relatively simple meta-cognitive skills in logical reasoning.

Do Students with Different Characteristics Take Part in Psychology Experiments at Different Times of the Semester?

ABSTRACT In this study we examined 15 personality and demographic differences between psychology students who took part in experiments at different times of the semester and different times of the day. In general, few significant relations were found and those that did emerge were small in magnitude. Females and freshmen signed up for experiments earlier in the semester. Females took part in their first experiment earlier in the semester, as did students who were Protestant and who came from smaller home towns. Students low in self-consciousness also tended to begin participating earlier. Extraverts participated earlier in the day than introverts. Results generally were consistent with previous findings of differences between research volunteers and non-volunteers. However, it was concluded that because of their small magnitude and inconsistency from site to site, with a few precautions experimenters probably need not be concerned that timing effects threaten the external validity of psychological research outcomes.
