Programs for visual psychophysics on the Amiga: A tutorial

A typical psychophysical experiment presents a sequence of visual stimuli to an observer and collects and stores the responses for later analysis. Although computers can speed up this process, paint programs that allow one to prepare visual stimuli without programming cannot read responses from the mouse or keyboard, whereas BASIC and other programming languages that allow one to collect and store observer’s responses unfortunately cannot handle prepainted pictures. A new programming language called The Director provides the best of both worlds. Its BASIC-like commands can manipulate prepainted pictures, read responses made with the mouse and keyboard, and save these on disk for later analysis. A dozen sample programs are provided.     

A comparative study of proprietary and nonproprietary vocational training graduates

Questionnaires were sent to 13,549 graduates of four types of proprietary and nonproprietary vocational training programs in four selected metropolitan areas of the United States. Initial responses were received from 5,215 graduates, a response rate of 38.5%. The survey featured an intensive follow-up to reach and estimate the characteristics of the nonrespondent population. Substantial differences favoring nonproprietary programs were found between proprietary and nonproprietary graduates in terms of economic gains following graduation and expressed satisfaction. Nevertheless, both types of programs were found to be generally effective in producing graduates with marketable skills; post-training salaries were high enough to indicate that the training was cost effective in all except proprietary computer training programs. The results supported several recommendations regarding the necessity for uniform standards of accountability in the regulation of vocational training programs, whether they are public or private.     

A microcomputer package for real-time skin conductance response analysis

A suite of programs has been developed to acquire data from a commercially available, highquality skin conductance meter, via a standard IEEE bus, on an Apple II or Apple lie microcomputer. These programs score and analyze stimulus-evoked skin conductance responses in a preset time window, and store the resultant data on disk, if required. Facilities for a manual override of the automatic scoring routine are available. The setup offers a method of scoring data as they are acquired; it uses currently recommended standards for skin conductance analysis and allows a high magnification of responses, without any need for continual monitoring, because of hardware facilities that automatically “back-off” a subject’s tonic skin conductance level.     

PSAAL: A LabVIEW 3 program for data acquisition and analysis in psychophysiological experiments

PSAAL (Physiological Signals Acquisition and Analysis in LabVIEW language) is a group of seven programs, written in LabVIEW 3.0 language and specialized for acquisition, analysis, reduction, and display of peripheral and central physiological data. The main characteristics of the programs are the wide range of use for most short-duration psychophysiological paradigms and the easy-to-use graphic interface. In addition, two noteworthy features of LabVIEW are included: the portability of the programs on Macintosh, PowerMac, IBM, HP-UX, and SUN computers, and the capability of handling acquisition on many National Instruments A/D boards, including the low-cost ones. PSAAL performs acquisition and simple reduction of peripheral physiological responses with 12- or 16-bit resolution according to the A/D board used. Analysis includes conversion of electrocardiogram into heart rate, the elaboration of the main parameters of skin conductance responses, electromyogram, startle reflex, and averaging of evoked potentials or other event-related physiological responses, under different experimental conditions. The programs allow the user to perform the organization of the data in a spreadsheet ready for most statistical packages and without the use of other spreadsheet applications.     

Comparison of vocational school graduates and dropouts

Graduates and dropouts from six vocational training programs were compared on data taken from school records and from their responses to a questionnaire. Results revealed that age, level of education, high school completion, marital status, physical or health disabilities, and GATB scores were not significant factors in distinguishing between graduates and dropouts in vocational training programs. Two significant factors were: (1) whether the vocational school offered the student's first choice of a vocational program, and (2) whether a student transferred from a college academic program to a vocational program or directly entered a vocational program without prior college academic work.     

A descriptive appraisal, 1935–1980

The writer evaluates the responses he received to causes, ideas and programs he advocated over his 45 year career as a Pastoral Theologian. He contsructs a four-fold typology of responses and discusses the concerns which have characterized his professional life, e.g. older persons, sexuality, ethics in pastoral care, theology in CPE, institutional chaplaincy, interprofessional cooperation, case study method, graduate programs in Religion and Personality, and Pastoral Theology. An evaluation of progress in these areas is followed by a concluding statement on his concerns.     

Microswitch-based programs for persons with multiple disabilities: an overview of some recent developments

Persons with multiple disabilities are often unable to interact with their environment due to their limited response repertoire. Microswitch programs are designed to help them control environmental events, generally preferred stimulation, through simple (feasible) responses. To make microswitch programs a more widely usable and relevant resource for intervention with these persons, a number of new developments were pursued in recent years. This paper examines three of those developments as specifically addressed in our research activity, namely, (a) assessment of new, nontypical responses and matching microswitches, (b) fostering of multiple responses and exercise of choice, and (c) targeting of habilitative and clinical (therapeutic) objectives. The encouraging outcomes of these developments are reviewed in relation to their potentially wide implications for daily practice and the need of additional developments in the area.     

The Practice of Fee Setting and Collection: Implications for Clinical Training Programs

The purpose of this article is to explore the empirical research that focuses on the association between fees and therapy outcomes as well as on therapists’ responses to issues of money. In addition, the authors will discuss implications for training programs surrounding the issue of client fees and offer suggestions for ways training programs might address the issue.     

Relation of scores on the Open Middle Test to self-control and academic achievement of inner-city fourth-grade children

The construct validity of the Open Middle Test, a measure of children's social problem-solving ability, was investigated by assessing its relationship to self-control (Self-control Rating Scale) and academic achievement (Wide-Range Achievement Test). Subjects were 113 minority fourth graders from two urban parochial schools. A significant correlation was obtained between Open Middle Test effectiveness scores of first responses and WRAT Reading scores. No other correlations were significant. However, mean differences were significant for Open Middle Test effectiveness ratings of first responses and chosen responses, suggesting possible deficits in the evaluation of self-generated problem solutions. Implications of the results for training programs and for the use of the Open Middle Test as an outcome measure are discussed.     

An experimental approach to language training in second language acquisition: Focus on negation

The effect of negation training in a second language on the expression of negation in the native language was investigated. Four-year-old children from bilingual (Spanish/English) homes who showed no expressive or receptive ability in Spanish negation and were either proficient or nonproficient in English negation received Spanish negation training. Children who were proficient in English negation maintained correct responses in English and showed increased correct responses in Spanish following simultaneous training in both languages or in Spanish alone. Children who were nonproficient in English negation demonstrated a decrease in correct English responses following training in Spanish alone; however, children who received training in English and Spanish simultaneously showed increases in correct responses in both languages. These findings suggest that language training programs with children learning a second language should consider the relationship of the two language training conditions (simultaneous vs. independent) with the child's level of native language proficiency.     

Textbook preferences among trainers of school psychologists

A survey of trainers of school psychologists was conducted in order to determine which texts in each of 16 areas of psychology they felt to be most relevant to the training of school psychologists. Usable responses were obtained from 48 out of 143 training programs. A 69-item bibliography of ranked choices in each area was presented. Possible trends indicated by the trainers' choices were discussed.     

The effects of fading on the acquisition and retention of oral reading

Comparisons were made between reading programs that involved superimposition of correlated pictoral and printed stimuli, fading of the pictoral stimuli, and overt observing (touching) responses. Nursey school children aged 4 to 5.8 yr learned and retained oral reading behavior better when fading was used; observing responses had no effect.     

Sex differences in reinforcement and punishment on prime-time television

Prime-time television programs were analyzed for frequencies of positive reinforcement and punishment exchanged among performers varying in age and sex. Results indicated that most responses were given by and directed to adult males. Moreover, while adult males exhibited and received similar frequencies of reinforcement and punishment, adult females were likely to give and to be the recipients of more reinforcement than punishment. Proportional analyses which controlled for sex differences in frequencies of responses revealed that females more often exhibited and received reinforcement, whereas males more often exhibited and received punishment. Results are interpreted from a social learning theory perspective and the implications for children's learning of positive and negative behaviors are explored.     

Win–Win–Win: The Influence of Company‐Sponsored Volunteerism Programs on Employees,NGOs, and Business Units

Although the number of firms adopting corporate volunteerism programs is rising steadily, very few firms are assessing the benefits of such programs on target groups, such as employees and nongovernmental organizations (NGOs), and identifying the conditions under which benefits to the various groups are maximized. This study addresses both by examining the conditions of employees’ corporate volunteer assignments that lead to increased employee engagement, sustainability of the volunteers’ project within the NGO, capability development for the business unit, and employees’ continuation of volunteerism. Using a longitudinal and multisource design, responses from 116 corporate volunteers from a global pharmaceutical organization are matched with responses from their NGO managers and their business unit managers at 3 points in time: at the start of the volunteer assignment, at the end of the assignment, and 6 months after the completion of the assignment. Across these outcomes, we found that employees’ volunteer assignments are most valuable when they are international, when the volunteers perceive that their projects contribute meaningfully the NGO's functioning, when volunteers have professional skills (and are able to use them), when there are opportunities for skills to be developed that can be applied in the volunteers’ regular work role, and when the NGOs have tangible resources to sustain the volunteers’ projects.     

A technique for quantifying and analyzing evoked responses

Two computer programs are discussed. One is used in the analog-to-digital conversion of and averaging of the responses; the other employs fuil-wave rectification and numerical integration as a method of comparing waveforms.     

Structural constraints on bimanual movements

Summary A theoretical framework is outlined, according to which structural constraints on bimanual movements can at least in part be understood as coupling between parameters of generalized motor programs. This framework provides a conceptual link between reaction-time data from experiments with bimanual responses, successive unimanual responses, and choice between left-hand and right-hand responses on the one hand and performance data obtained with concurrently performed continuous movements or sequences of discrete responses on the other. On the basis of data obtained with different methods for the study of intermanual interactions, a distinction is drawn between steady-state and transient constraints, and the hypothesis that the tendency to coactivate homologous muscles originates from a transient coupling of program parameters is applied to a variety of observations on performance in different tasks. Finally, the notion of transient constraints is applied to other types of intermanual interdependencies and to interpersonal coordination; the possible emergence of transient constraints from steady-state constraints through progressive development of inhibitory pathways in childhood is discussed, as is the potential biological significance of transient constraints.Part of the work reported in this paper was done while I enjoyed the hospitality on the NIAS, Wassenaar (NL)     

SPSS programs for the measurement of nonindependence in standard dyadic designs

Dyadic research is becoming more common in the social and behavioral sciences. The most common dyadic design is one in which two persons are measured on the same set of variables. Very often, the first analysis of dyadic data is to determine the extent to which the responses of the two persons are correlated—that is, whether there is nonindependence in the data. We describe two user-friendly SPSS programs for measuring nonindependence of dyadic data. Both programs can be used for distinguishable and indistinguishable dyad members. Inter1.sps is appropriate for interval measures. Inter2.sps applies to categorical variables. The SPSS syntax and data files related to this article may be downloaded as supplemental materials from brm.psychonomic-journals.org/content/supplemental.     

The structure of cockpit management attitudes

A revised version of the Cockpit Management Attitudes Questionnaire (CMAQ) is introduced. Factor analyses of responses from 3 different samples reveal comparable factor structure (previous attempts to factor analyze this measure had produced equivocal results). Implications for the measurement of attitudes and the assessment of attitude change are discussed. It is argued that the CMAQ will benefit both special training programs and efforts to explore attitude-performance linkages in air-transport operations.     

PSYCHOL: A computer language for experimentation

Psychologists employing digital computers in the laboratory to control experimental procedure must construct programs. A language is described that incorporates many data representations and manipulations useful in presenting stimuli, collecting responses, and deciding the course of an experiment. PSYCHOL is an extension to a subset of ALGOL, with data types extended to include simple lists, strings of text, historic variables, and responses. Timing mechanisms, stimulus presentation, and data recording instructions expand the operations available within the language.     

Priced just for me: The role of interpersonal attachment style on consumer responses to customized pricing

Customized pricing is an increasing phenomenon in the marketplace, but little is known about factors influencing consumer responses to customized pricing. The present paper seeks to gain an understanding of how, why, and when this emerging pricing mechanism may offer benefits. Specifically, this research focuses on how consumers respond to customized pricing tactics and, more specifically, on how interpersonal attachment orientations impact consumers' responses to prices offered in the presence of a customized pricing program. The results of 3 studies suggest that customized pricing programs likely create an expectation for a discounted price among securely attached individuals, such that these consumers are dissatisfied paying the shelf price in the presence of a customized pricing program. Overall, the results provide evidence that, although customized pricing programs are often used to enhance consumer evaluations, they may not always be effective. This paper advances prior research by integrating important considerations for both pricing and customization strategies based on individual and situational differences in attachment orientations.
