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.     

Convergent methods in psychomusical research based on integrated,interactive computer control

Much of what we learn from an experiment depends on what we ask of the subjects and how we ask it. Most music perception and cognition research is implemented using a single methodology. Recently, questions have been raised about the validity and generalizability of such a limited approach, particularly regarding such complicated theoretical constructs as musical tonality. We propose that a useful technique is to converge on the answer to experimental questions by applying multiple methods, in essence, simultaneously investigating the central research question as well as ancillary questions of method. Such an approach is facilitated by a computer hardware and software system that integrates experimental design, data collection, data analysis, and data dissemination, linking off-the-shelf components through standard file formats and data-exchange protocols. The list-based system, using an IBM-type PC running Windows 3.0, handles real-time natural sound sampling and playback, signal synthesis and analysis, MIDI input and output, digitized picture display, and various subject-response mechanisms. On the basis of graphical icons, the integrated system can be used to build custom experimental designs. Examples of convergent psychomusical experiments that were designed, implemented, and analyzed using the system are discussed.     

The Analysis of Single-Case Research Data: Current Instructional Practices

Visual analysis is the predominant method of analysis in single-case research (SCR). However, most research suggests that agreement between visual analysts is poor, which may be due to a lack of clear guidelines and criteria for visual analysis, as well as variability in how individuals are trained. We developed a survey containing questions about the content and methods used to teach visual and statistical analysis of SCR data in verified course sequences (VCS) and distributed it via the VCS Coordinator Listserv. Thirty-seven instructors completed the survey. Results suggest that there is variability across instructors in some fundamental aspects of data analysis (e.g., number of effects required for a functional relation) but a great deal of consistency in others (e.g., emphasizing visual over statistical analysis). We discuss our results along with their implications both for teaching students to analyze SCR data and for conducting additional research on behavior-analytic training programs.

Experimental and Quasi-Experimental Designs in Visitor Studies: A Critical Reflection on Three Projects

Identifying causal relationships is an important aspect of research and evaluation in visitor studies, such as making claims about the learning outcomes of a program or exhibit. Experimental and quasi-experimental approaches are powerful tools for addressing these causal questions. However, these designs are arguably underused in visitor studies. In this article, we offer examples of the use of experimental and quasi-experimental designs in science museums to aide investigators interested in expanding their methods toolkit and increasing their ability to make strong causal claims about programmatic experiences or relationships among variables. Using three designs from recent research (fully randomized experiment, posttest only quasi-experimental design with comparison condition, and posttest with independent pretest design), we discuss challenges and tradeoffs related to feasibility, participant experience, alignment with research questions, and internal and external validity. We end the article with broader reflections on the role of experimental and quasi-experimental designs in visitor studies.     

"Golden oldies" in a laboratory course in the experimental analysis of behavior

A common problem in teaching undergraduate courses in the experimental analysis of behavior (EAB) is that the contemporary research literature is largely not comprehensible to most undergraduates. A suggested solution is the use of research articles from the early days of EAB. These are not only easy to understand but provide additional educational benefits. A reading list and an organizational structure for an undergraduate laboratory course in EAB are suggested.     

Bringing history to life: simulating landmark experiments in psychology

The course in history of psychology can be challenging for students, many of whom enter it with little background in history and faced with unfamiliar names and concepts. The sheer volume of material can encourage passive memorization unless efforts are made to increase student involvement. As part of a trend toward experiential history, historians of science have begun to supplement their lectures with demonstrations of classic physics experiments as a way to bring the history of science to life. Here, the authors report on computer simulations of five landmark experiments from early experimental psychology in the areas of reaction time, span of attention, and apparent motion. The simulations are designed not only to permit hands-on replication of historically important results but also to reproduce the experimental procedures closely enough that students can gain a feel for the nature of early research and the psychological processes being studied.     

Cognition in marriage: Current status and future challenges

Research on cognition in marriage is examined by posing two questions. The first asks what has been learned about marital distress from research on cognitive variables. It is addressed by examining data on (a) associations between cognitive variables and marital distress, (b) artifactual explanations for such associations, and (c) the causal impact of cognitive variables on spouse satisfaction and spouse behavior. This analysis identifies the study of knowledge structures as a theme that unifies existing research and illustrates how explicit recognition of this theme can advance future inquiry. The second question asks what has been learned from research on cognitive interventions with couples and leads to a number of suggestions for maximizing the informativeness of outcome studies. It is argued that future progress requires expanding the conception of cognition that informs marital research and integrating the study of marriage with both broader efforts to understand close relationships and to understand cognition.     

Editorial overview: Analytic and methodological innovations for suicide‐focused research

This editorial overview provides an introduction to the Suicide and Life‐Threatening Behaviors Special Issue: “Analytic and Methodological Innovations for Suicide‐Focused Research.” We outline several challenges faced by modern suicidologists, such as the need to integrate different analytical and methodological techniques from other fields with the unique data problems in suicide research. Therefore, the overall aim of this issue was to provide up‐to‐date methodological and analytical guidelines, recommendations, and considerations when conducting suicide‐focused research. The articles herein present this information in an accessible way for researchers/clinicians and do not require a comprehensive background in quantitative methods. We introduce the topics covered in this special issue, which include how to conduct power analyses using simulations, work with large data sets, use experimental therapeutics, and choose covariates, as well as open science considerations, decision‐making models, ordinal regression, machine learning, network analysis, and measurement considerations. Many of the topics covered in this issue provide step‐by‐step walkthroughs using worked examples with the accompanied code in free statistical programs (i.e., R). It is our hope that these articles provide suicidologists with valuable information and strategies that can help overcome some of the past limitations of suicide research, and improve the methodological rigor of our field.     

Data-driven type checking in open domain question answering

Many open domain question answering systems answer questions by first harvesting a large number of candidate answers, and then picking the most promising one from the list. One criterion for this answer selection is type checking: deciding whether the candidate answer is of the semantic type expected by the question. We define a general strategy for building redundancy-based type checkers, built around the notions of comparison set and scoring method, where the former provide a set of potential answer types and the latter are meant to capture the relation between a candidate answer and an answer type. Our focus is on scoring methods. We discuss nine such methods, provide a detailed experimental comparison and analysis of these methods, and find that the best performing scoring method performs at the same level as knowledge-intensive methods, although our experiments do not reveal a clear-cut answer on the question whether any of the scoring methods we consider should be preferred over the others.     

Die DPG-Praxis-Studie

All psychotherapeutic methods must be scientifically evaluated. Empirical evaluation of evidence is a prerequisite for acceptance as scientific psychotherapy as well as for payment by health insurance. Currently the psychotherapy methods accepted within the German health system (behavioural therapy, psychodynamic psychotherapy, and analytic psychotherapy) are reviewed by a governmental evaluation committee concerning evidence, necessity and cost-effectiveness. The DPG practice study has basically two aims: 1) to conduct a large naturalistic study to investigate effectiveness, sustainability and economic aspects of psychodynamic and analytic psychotherapy and 2) to offer a framework for psychoanalytic institutes, members, candidates or groups to realize own research ideas by collecting additional data within the study. The present article describes the background, main research questions, structure and design of the DPG practice study with regard to the evaluation questions.     

The course in the history of psychology: present status and future concerns

The present study provides a turn-of-the-century status report on the teaching of the history of psychology in colleges and universities in the United States. The data indicate that the course is offered regularly in most departments of psychology and is frequently required of majors; these findings are consistent with earlier research. Most instructors teach the course largely out of personal interest and self-taught expertise with their primary teaching and research commitments to other areas of psychology. Few instructors engage in publication of research and scholarship in the history of psychology, although there are 2 journals in the field that provide an outlet for scholarship. The few positions that allow for primary commitment to teaching and research in the history of psychology is a possible cause of concern for the future of the course and for its place in the education of psychologists in the 21st century.     

Technologies to reliably transduce the topographical details of pigeons’ pecks

Pigeons’ pecking has long been a subject of interest in behavioral research, with the response typically being viewed as unitary. Recent experiments done with computer-controlled devices have revealed that this response is at least bipartite in character, with beak opening and response location (head transport) as its components. In addition, experimental work has demonstrated that these response components may be separately influenced and controlled by respondent and operant conditioning procedures. The detailed topographic analysis and technology that have emerged may provide a background for similar work with other behavioral systems.     

A Feasibility Trial of Mental Health First Aid First Nations: Acceptability,Cultural Adaptation,and Preliminary Outcomes

The Mental Health First Aid First Nations course was adapted from Mental Health First Aid Basic to create a community‐based, culturally safe and relevant approach to promoting mental health literacy in First Nations contexts. Over 2.5 days, the course aims to build community capacity by teaching individuals to recognize and respond to mental health crises. This feasibility trial utilized mixed methods to evaluate the acceptability, cultural adaptation, and preliminary effectiveness of MHFAFN. Our approach was grounded in community‐based participatory research principles, emphasizing relationship‐driven procedures to collecting data and choice for how participants shared their voices. Data included participant interviews (n = 89), and surveys (n = 91) from 10 groups in four provinces. Surveys contained open‐ended questions, retrospective pre‐post ratings, and a scenario. We utilized data from nine facilitator interviews and 24 facilitator implementation surveys. The different lines of evidence converged to highlight strong acceptability, mixed reactions to the cultural adaptation, and gains in participants’ knowledge, mental health first aid skill application, awareness, and self‐efficacy, and reductions in stigma beliefs. Beyond promoting individual gains, the course served as a community‐wide prevention approach by situating mental health in a colonial context and highlighting local resources and cultural strengths for promoting mental well‐being.     

RELEASE FROM PI: Comparison of traditional and computer modules in an experimental psychology laboratory

RELEASE FROM PI is a computer-controlled participatory module designed for use by students in laboratory sections of an experimental psychology course. It allows the student subjects to trace their recall performance across sets of four lists when the fourth list changes in physical characteristics or semantic category. The performance of students participating in this computer module was compared with that of students receiving a traditional procedure with a human experimenter. All other aspects of the laboratory session were equated as much as possible. The recall data showed that the traditional procedure produced better recall and greater release with a semantic shift. However, both methods resulted in roughly equivalent learning (as measured by multiple-choice questions) and student evaluation ratings. Implications for the use of computers in instruction and research are examined.     

VSearch: Macintosh software for experiments in visual search

In this paper, we describe software that turns a Macintosh computer into an off-the-shelf tool for experiments on visual search. Our design goals included portability (between members of the Macintosh computer family and between various research settings), user-friendliness (equivalent to Macintosh programming standards), flexibility (to allow replication and extension of important experiments on visual search), and adaptability (very short design-to-data and data-to-analysis turnaround times). We describe how the software meets these goals in three major phases of an experiment: stimulus construction, experimental control, and statistical analysis. We then list several landmark studies of visual search that can be easily designed and extended with the software. Finally, we outline plans for expanding the experimental variations that will be supported in future versions of the software.     

教材内容的情感性分析及其处理策略

人们对教材的教学心理学分析研究相对较少,仅有的也多囿于认知维度。奥苏贝尔在其意义学习理论框架下研究了教材的意义性及其学习条件问题,并提出了著名的处理教材内容的先行组织者策略,然其研究仍属认知维度。其实,教材也是构成教学中情感现象的一个重要源点,对其进行情感性分析研究,将有助于从情感维度系统优化教学。故本文对教材内容进行较系统的情感分析,归纳为蕴涵显性、隐性、悟性和中性情感因素的四大类,并在教学实验
