A solid-state device for providing graphic records of various behavioral and physiological events in much the same manner as does the electromechanical cumulative recorder is described. This transistorized version of the cumulative recorder produces a noise-free (electrical and acoustical) analog cumulative record on analog recorders. The circuit provides for such features as: built-in calibrator; internal-reset oscillator; variable incremental step amplitude; and a FET op-amp to provide a constant. drift-free output level over long and extended reset periods. The output of the device can be displayed on one channel of a polygraph recorder with adjacent channels providing physiological and behavioral data to produce a real time correlation of analog and event signals.  相似文献

A system is described involving three tape recorders and a control device whereby dichotic tapes can be prepared with onset alignment accurate to a few milliseconds, or to a measured asynchrony if required. No modifications of any sort are necessary for the three tape recorders. The two channels are separately recorded in the speaker’s own time, the only requirement being that the separate words be spoken with an interword interval of 350 msec or more, to provide sufficient time for starting and stopping the system. A tone burst is placed directly on tape on another channel ahead of each word, the latter being delayed by recording in tandem through two tape recorders. The first recorder is set to the delay (echo, NAB) facility, while the tone is recorded directly on the second. Subsequently, when this is done for each item on the two speech channels, the device, described below. utilizes the tone bursts to align the two input recorders. It then rerecords each pair of words on to the third (output or dichotic) machine, to the desired synchrony/asynchrony, and interitem interval. The system can be left to align the two channels automatically. A maximum repetition rate of two dichotic pairs every 1.3 sec can be achieved with Revox A77 tape recorders.  相似文献

A simple method of increasing speech rate by shortening or removing silent hesitation from speech recordings is described. Two tape recorders and a voice key are used. The transmitting tape recorder is modified to have two playback heads in line. The onset and offset of speech signals fed from the first head, via a voice key, control the tape transport of the receiving tape recorder. The speech signals from the second playback head are fed directly to the line input of the receiving tape recorder. Time delays can be arranged so that the tape transport of the receiving machine is only in motion for the duration of the speech signals. The logic circuit of a suitable voice key with independently variable onset and offset delay times is also described.  相似文献

A simple and inexpensive system for coding and recording interaction patterns in small groups is described. It consists of a keyboard and a standard tape recorder, and it is capable of storing sequential data using up to 36 codes. Its main application is in the study of speaker-target patterns, but it can also be used in encoding up to 12 behavioral codes, or six speakers and 6 codes. The keyboard costs less than $200 and is used with conventional tape recorders and minicomputers available at most research sites.  相似文献

The present study explored the effectiveness of a unique intervention for couple therapy, the Canned Attitude Method (a technique developed by Brent Atkinson), which utilized a digital recorder in and between therapy sessions. Participant dyads were randomly assigned to the intervention group utilizing the digital recorders or the control group, in which Pragmatic/Experiential Therapy for Couples (Atkinson in J Syst Ther 17:18–35, 1998) was conducted without the use of digital recorders. Both the intervention and the control groups were composed of five couples each for a total of 20 participants. This study hypothesized that the use of the Canned Attitude Method in couple therapy would produce a significant change in marital satisfaction, emotional flooding, and positive psychological tendencies associated with intimate relationships. Findings approached significance, demonstrating decreases in the experience of emotional flooding, gains in relationship satisfaction, and a shift towards positive attributes within the couples’ relationships.  相似文献

A procedure was employed that enabled a teacher to bring inappropriate verbalizations under control in a classroom of approximately 25 fifth- and sixth-grade students. Contingent point loss for inappropriate verbalizations was correlated with a low but steady rate of such verbalizations. Point gain contingent upon quiet behavior produced a marked decrease in inappropriate verbalizations. A return to contingent point loss was accompanied by an increasing rate of inappropriate verbalizations. Verbalizations decreased when quiet behavior was reinforced again. A noteworthy feature of the study was the utilization of students from within the class to act as data recorders. A reliability check indicated satisfactory agreement between the recorders.  相似文献

A portable four-channel electroencephalogram (EEG) cassette recording system has been designed which offers good performance, is simple to construct, and moderate in cost. The recorder is compatible with a commercially available, portable, battery-operated power source, and is therefore usable in the field where line power is unavailable. The system incorporates a small, lightweight, portable, battery-powered oscilloscope which provides monitoring and playback capability. While a few experimental portable EEG recorders have been reported in recent years with more channel capacity or perhaps lighter weight, the engineering details of these units are rarely published and, in any event, would require a substantial effort for most electronics support shops to reproduce. The recording system described here, however, should be within the capability of most electronics support groups to assemble in a very short time and provide good performance.  相似文献

From its inception in the 1930s until very recent times, the cumulative recorder was the most widely used measurement instrument in the experimental analysis of behavior. It was an essential instrument in the discovery and analysis of schedules of reinforcement, providing the first real-time analysis of operant response rates and patterns. This review traces the evolution of the cumulative recorder from Skinner's early modified kymographs through various models developed by Skinner and his colleagues to its perfection in the 1950s, and then into the 1960s when it proliferated as different scientific instrument companies began marketing their own models of the cumulative recorder. With the rise of digital computers, the demise of the cumulative recorder as a scientific instrument was inevitable; however, the value of the cumulative record as a monitoring device to assess schedule control of behavior continues. The cumulative recorder remains, along with the operant conditioning chamber, an icon of Skinner's approach to psychology.  相似文献

While anxiety research frequently uses only self-report measures to assess dimensions of state and trait anxiety, the present study sought to corroborate these self-report measures using a physiological measure, namely heart rate. Another aim of the present study was to test the multidimensional interaction model of anxiety in a social evalua-tion situation (i.e., a seminar presentation), using a physiological measure of state anxiety. Graduate psychology students completed a state anxiety questionnaire and were attached to a heart rate recorder prior to a class seminar presentation. One week later, students completed trait and state anxiety questionnaires and were again at-tached to a heart rate recorder prior to seminar observation by others. Heart rate was elevated during seminar presentation relative to seminar observation, reached maxi-mum values during the first 15 minutes of seminar presentation and then decreased over time. State anxiety scores indicate that participants were experiencing consider-ably more anxiety just before presenting the seminar than just before observing a seminar. Heart rate during seminar presentation was significantly correlated with self-report state anxiety and self-report social evaluation trait anxiety, but not with seminar grade. Support was found for the multidimensional interaction model of anxiety using the physiological measure (i.e., heart rate). A modified version of this paper was presented at the 101st Annual Convention of the American Psychological Association. This research was supported, in part, by Grant No. 410-94-1473 from the Social Sciences and Humanities Research Council of Canada (SSHRC) to the second author.

A microcomputer system for real-time control of experiments in cognitive psychology is described. The microcomputer serves as an interface that allows a remote timesharing computer to control the timed display of textual material on CRTs and collect response times accurate to 1 msec. It can control two CRT subject stations presenting the same or different experiments and control other devices such as slide projectors and tape recorders. It is argued that such special-purpose microcomputer interfaces provide a real-time laboratory with significantly less effort than does the more traditional laboratory minicomputer.  相似文献

The Rockefeller University, New York, New York 10021 Events such as barpresses or licks, which may occur at any time during the day, are often clustered into bouts. The internal structure of such bouts can be recorded using an AM tape recorder, running the tape recorder only while bouts are in progress, and can later be analyzed off-line on a digital computer.  相似文献

A graphical method has been developed for the concurrent recording of heart beats and lever responses during behavioral experiments. The EKG signal fed into any DC amplifier goes to a fixed level trigger circuit and relay driver with its own power supply. The signal from this drives any standard cumulative recorder. Lever response rates are recorded concurrently on an additional cumulative recorder using the same paper speed.  相似文献

A laboratory control system based upon the Imsai 8080 microcomputer is described. This system is capable of programming separate events in each of five animal operant chambers and recording the resulting behavioral data. The interface between the computer and the chambers is compatible with the 28-V dc nature of these chambers and various peripheral devices, such as cumulative recorders. At present, system software is based on the 8080 assembly language, while the BASIC language is used for data analysis. Cost considerations and comparisons with minicomputers are discussed.  相似文献

A new method for the analysis of complex avian song repertoires is introduced. The method consists of sending a tape-recorded bird-song signal through five narrow band-pass filters and then to a five-channel high-speed pen recorder. A coding method that allows a researcher to convert the output from the pen recorder to numbers for later analysis by computer is described.  相似文献

The dynamic limitations of eye movement recorders can distort the measurement of fast eye movements such as saccades and nystagmic quick phases. In this paper, the effects of the bandwidth and noise of recording methods and the problems incurred by digital sampling are discussed theoretically with respect to the measurement of peak velocity and duration of fast eye movements. As a practical example, a TV-based infrared corneal reflex system is examined and a method for calibrating it for peak velocity measurement is described.  相似文献

Flight mills to which flying insects are tethered, and which allow measurement of locomotion in a circular path, are used to measure flight capability in terms of frequency, duration, velocity, and distance. Also, they are adaptable to measurement of physiological processes such as respiration and energy consumption. We describe a flight-mill system with floating magnets and Teflon® bearings in its rotor that minimize frictional drag. Rotation (of the mill rotor) is transduced by interruption of a light beam to a phototransistor, which produces a signal monitored by a specially constructed event recorder. The event recorder temporarily stores the data from each mill and then transmits them in proper format for permanent storage on seven-track magnetic tape. The system allows simultaneous data collection from 18 individual insects and provides a computerized interpretation of their performance. The result is an analysis of all the significant parameters of flight that can be derived by measuring duration, velocity, distance, and frequency.  相似文献

The Transcultural Integrative Ethical Decision‐Making Model in counseling addresses the need for including cultural factors in the process of ethical dilemma resolution. This transcultural model incorporates state‐of‐the‐art concepts from multicultural theory into an ethical decision‐making model that is adapted primarily from the Integrative Model developed by V. M. Tarvydas (1998). When appropriate, this transcultural model includes aspects of other ethical resolution models, such as R. R. Cottone's (2001) Social Constructivist Model and A. H. Davis's (1997) Collaborative Model. The proposed model is presented in a step‐by‐step, linear format that can be used by counselors facing ethical dilemmas in a variety of settings and with different cultural groups.  相似文献
