MouseTrace: A better mousetrap for catching decision processes

This paper describes MouseTrace, a computer program designed to monitor the process by which people make decisions by presenting complex choice information to subjects in the form of an alternative-by-attribute matrix. MouseTrace is a Windows-based extension of another program called MouseLab; however, MouseTrace accommodates significantly more information and allows for multiple responses, as well as multiple decision stages. It is also easier to use for both subjects and experimenters and more sophisticated in terms of its features and the data it records. These data include what information was examined, when, and in what order. This information can be used to derive a variety of cognitive process measures, including those related to search depth, sequence, and content, which in turn can be used to provide unique insights into decision-making theory, individual differences, and a variety of decision variables.     

Searching for a better story: harnessing modern and postmodern positions in family therapy

In this paper it is argued that modern and postmodern positions on reality and knowledge should not create a theoretical division in family therapy and that rather, by harnessing the two together, each may restrain the other. This combination creates the potential for drawing widely from the whole field of family therapy as well as challenging the separation of mainstream family therapy models from psychoanalysis. The concept of better story is used to replace both the polarized modern position of an objective discoverable truth and the polarized postmodern position of all stories having equal validity. It is suggested that better stories, which evolve in the meeting of family and therapist, may include those which are more congruent, object-adequate, encompassing, holding, shared, emotional, conscious, just, provisional and hopeful.     

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.     

The Macintosh as a user-friendly laboratory for perception and cognition

We present a radically user-friendly Macintosh laboratory, MindLab, for instruction in perception and cognition. MindLab’s forte is its ability to display pictorial stimuli, including digitized photographs, transferred via the clipboard from Macintosh graphics applications. An experiment is programmed by specifying sequences of event primitives, represented by icons, to which stimuli, temporal parameters, and feedback options are assigned.     

Psychmuse: A Macintosh system for psychomusicology research

A software system developed with HyperCard has been designed to support research relying on musical stimuli. The software accesses a set of digitized sounds in memory that consist of chromatic scale notes for the piano, harp, and guitar. Menu options allow experimenters to create monophonic melodies, to arrange melodies in a prescribed order, and to present them in a flexible format for a variety of psychological tasks. In addition to supporting experimental research projects, the software can also be used to demonstrate certain fundamental principles of auditory perception and cognitive psychology.     

ArtWare: Macintosh multimedia software for aesthetics research

This paper describes ArtWare, a HyperCard stack for the Apple Macintosh that allows researchers to configure and run simple experiments in visual aesthetics. ArtWare allows researchers to (1) choose paintings or other works of art from commercially available laser discs to use as stimuli, (2) create and edit sets of semantic differential response scales, and (3) create an experiment stack that randomizes the presentation of stimuli and scales as well as collects data from subjects. In addition, the paper discusses revisions planned for the current software to broaden its utility to areas beyond visual aesthetics.     

Tachistoscopic software for the Macintosh

The emulation of a tachistoscope with a Macintosh microcomputer and Pascal language is presented here. The software described is a complete program for the presentation of textual stimuli on the Macintosh screen and includes the recording of reaction times. The stimulus coordinates on the screen are user defined and variable from trial to trial for specific visual angles. The position of a fixation point on the screen and the distance between the subject and the plane of the screen, as well as the particular screen resolution, are taken into account in computing the visual angle.     

Tachistoscopic software for Macintosh computers

The requirements for accurate presentation of short-duration stimuli on, raster display monitors are summarized, and existing packages for instantiating such displays are evaluated. A new soft-ware package that provides tachistoscopic functions for Macintosh computers is described. This software, called MacTach, performs video-buffer switching, allowing tachistoscopic presentation of large or multibit depth images that is not available with alternative methods. Compatibility routines and verification procedures allow compatibility with all Macintosh computers. Applications for animation, motion, and dichoptic presentations are discussed.     

Toolbox-based routines for Macintosh timing and display

Pascal routines are described for several real-time operations on Macintosh computers. Methods are presented for millisecond timing and for high-speed transfer of arbitrary bit-image displays to the screen. All routines are based on Toolbox procedures available on virtually all Macintosh computers.     

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.     

Eye movements and morphological segmentation of compound words: There is a mouse in mousetrap

In two experiments, readers' eye movements were monitored as they read sentences containing compound words. In Experiment 1, the frequency of the first and second morpheme was manipulated in compound words of low whole word frequency. Experiment 2 compared pairs of low frequency compounds with high and low frequency first morphemes but identical second morphemes that were embedded in the same sentence frames. The results showed significant effects of the frequency of both morphemes on gaze duration and total fixation time on the compound words. Regression analyses revealed an influence of whole word frequency on the same measures. The results suggest that morphemic constituents of compound words are activated in the course of retrieving the representation of the whole compound word. The fact that the frequency effects were not confined to fixations on the morphemic constituents themselves implies that saccadic eye movements are implemented before morphemic retrieval has been completed. The results highlight the importance of developing more precise models of the perceptual processes underlying reading and how they interact with the processes involved in lexical retrieval and comprehension.     

Searching for Sharks and a Second Self

Twenty years ago, Pastoral Psychology published “The Extra Mile—Case History of a Homicide” (Moss, Pastoral Psychology 42:107–136, 1993, p.134). In that autobiographical vignette, I argued that pastoral theology has a responsibility to: “1) articulate contemporary ultimate concerns, 2) clarify healthy avenues for compensation, and 3) tell stories about the hopeful revelations of God’s providence in a broken world” (Moss, Pastoral Psychology 42:107–136, 1993, p.134). This story illustrates all three of these points by recording a psychological fragmentation and restoration resulting from the death of a dear friend—“a friend who sticks closer than a brother” (Prov. 18:24). Aristotle referred to this type of friend as “a second self.” In the Celtic church such a person was anam cara, a Gaelic expression for “soul friend.” A few years ago I lost such a friend to cancer. During my grieving process I created a private tribute from our unfulfilled wish to go on one more adventure together—specifically, a shark hunt. The capture and release of sharks is a unique extreme sport. It is also the vehicle by which I finally resolved my grief: I reunited with my second self by means of an image in the eye of a requiem shark, a reflection of anam cara. The interrelated layers of this occurrence—particularly its coincidences—evidence Providence, as well as provide an example of a “Contact with the Dead Experience” described by Andrew Greeley and myself some 20 years ago in the Journal of Religion and Health (Moss, Journal of Religion and Health 29:261–283, 1990).     

Student statistics programs for the Macintosh

This paper reviews 15 statistics programs for the Macintosh. All are intended for student use, often in conjunction with a statistics course, and are available for under $100. Of the general-purpose programs, Data Desk and StatView offer the most appealing combination of features, Macintosh interface, and student-accessible manual. Minitab is also recommended, especially in situations where some students will be using Macs and others using PCs. In addition to the analysis-only programs, two other applications present interesting combinations of statistics and other features. DataSim offers outstanding data generation and experiment simulation along with very complete, and psychology-oriented, statistical analysis. HyperStat combines an entire statistics textbook in hypertext format with a complete data analysis package. Finally, for special situations where simple statistics are all that are required, InStat is recommended because of its tutorial features and very simple interface.     

SuperLab: General-purpose Macintosh software for human experimental psychology and psychological testing

SuperLab is a general-purpose psychology testing package for the Macintosh. SuperLab presents static visual and auditory stimuli in blocks of trials, each trial consisting of a user-specified sequence of stimuli. Responses can be recorded from the keyboard or from switches connected to an I/O board. Stimuli can be contingent on subjects’ responses, allowing feedback based on response accuracy. Timing uses Time Manager routines from the Macintosh Toolbox. Data are recorded in a text format with tabs delimiting fields, allowing analysis and presentation by other Macintosh spreadsheet, statistics, and graph-making applications. SuperLab has a Macintosh user interface for developing experiments. Psychological tasks can also be designed and modified with any application that generates a text format file.     

Searching for the sequential line-up advantage: a distinctiveness explanation

Gronlund ( 2005 ) proposed that one factor leading to a sequential line-up advantage could be the greater likelihood of recollecting distinctive information about a perpetrator when using a sequential line-up. Since then questions have been raised about the robustness of the sequential advantage and the possible moderating role of line-up fairness and suspect position. We manipulated these factors as well as suspect/target distinctiveness in two experiments. A sequential advantage occurred only after encoding a distinctive target, both for biased line-ups (Experiment 1) and fair line-ups (Experiment 2). Remember-Know results were consistent with the greater use of a recall-to-reject strategy in target-absent sequential line-ups. This provided support for the first process-based explanation of the sequential line-up advantage. No consistent position effects were found, but this might be due to the line-up recognition paradigm used, in which each participant viewed a line-up for each of several targets. Theory-based explorations of eyewitness identification are necessary to continue to delineate the underpinnings of the sequential line-up advantage.     

Power & Effect: A statistical utility for Macintosh and Windows systems

Significance tests are not the only step in statistics. Other considerations include effect sizes and adequate sample sizes for a respectable level of statistical power. However, many statistical packages are spotty in their offerings of effect size, complex, and lack a friendly interface. Textbooks may have limited coverage, and calculations entail several formulas and tables. Power & Effect offers a calculator- and formula-based metaphor to compute popular measures of effect size, simple significance tests between effect sizes, combining of effect sizes, simple significance tests based on known statistical values, and sample size determinations based on predicted results or effect size.
