The other modality: Auditory stimuli in language switching

Language switching studies typically implement visual stimuli and visual language cues to trigger a concept and a language response, respectively. In the present study we set out to generalise this to another stimulus modality by investigating language switching with auditory stimuli next to visual stimuli. The results showed that switch costs can be obtained with both auditory and visual stimuli. Yet, switch costs were relatively larger with visual stimuli than with auditory stimuli. Both methodological and theoretical implications of these findings are discussed.     

Differential responding in the presence and absence of discriminative stimuli during multielement functional analyses

We evaluated the extent to which discriminative stimuli (S(D)s) facilitate differential responding during multielement functional analyses. Eight individuals, all diagnosed with mental retardation and referred for assessment and treatment of self-injurious behavior (SIB) or aggression, participated. Functional analyses consisted of four or five assessment conditions alternated in multielement designs. Each condition was initially correlated with a specific therapist and a specific room color (S(D)s), and sessions continued until higher rates of target behaviors were consistently observed under a specific test condition. In a subsequent analysis, the programmed S(D)s were removed (i.e., all conditions were now conducted by the same therapist in the same room), and sessions continued until differential responding was observed or until twice as many sessions were conducted with the S(D)s absent (as opposed to present), whichever came first. Results indicated that the inclusion of programmed S(D)s facilitated discrimination among functional analysis conditions for half of the participants. These results suggest that the inclusion of salient cues may increase either the efficiency of functional analyses or the likelihood of obtaining clear assessment outcomes.     

Earning and obtaining reinforcers under concurrent interval scheduling

Contingencies of reinforcement specify how reinforcers are earned and how they are obtained. Ratio contingencies specify the number of responses that earn a reinforcer, and the response satisfying the ratio requirement obtains the earned reinforcer. Simple interval schedules specify that a certain time earns a reinforcer, which is obtained by the first response after the interval. The earning of reinforcers has been overlooked, perhaps because simple schedules confound the rates of earning reinforcers with the rates of obtaining reinforcers. In concurrent variable-interval schedules, however, spending time at one alternative earns reinforcers not only at that alternative, but at the other alternative as well. Reinforcers earned for delivery at the other alternative are obtained after changing over. Thus the rates of earning reinforcers are not confounded with the rate of obtaining reinforcers, but the rates of earning reinforcers are the same at both alternatives, which masks their possibly differing effects on preference. Two experiments examined the separate effects of earning reinforcers and of obtaining reinforcers on preference by using concurrent interval schedules composed of two pairs of stay and switch schedules (MacDonall, 2000). In both experiments, the generalized matching law, which is based on rates of obtaining reinforcers, described responding only when rates of earning reinforcers were the same at each alternative. An equation that included both the ratio of the rates of obtaining reinforcers and the ratio of the rates of earning reinforcers described the results from all conditions from each experiment.     

History and Method of Charles V. Gerkin’s Pastoral Theology: Toward an Identity-Embodied and Community-Embedded Pastoral Theology,Part II. Method

The purpose of this article is to explore the legacy of Charles V. Gerkin’s pastoral theology and to construct a method of pastoral theology. In Part I, I will trace within a larger context of pastoral theology the history of Gerkin’s pastoral theology since his early clinical praxis. In Part II, I will explore his method of developing pastoral theology and construct a renewed critical and constructive method of pastoral theology, reflecting on the implications of exploring the history and method of his pastoral theology.     

现代新儒学基本理论的自我消解

现代新儒家的基本理论主张可概括为 :儒学主流说、儒家道统说、新内圣外王之道、良知自我坎陷说、儒学复兴论。现代新儒学第三代重要代表人物已经偏离或放弃了这些基本的理论和主张 ,走上了文化多元化之路。这无疑意味着现代新儒学基本理论的自我消解。现在 ,这股文化思潮的高峰已经过去 ,已经成为历史。     

Making the Parents as Partners Principle a Reality: The Role of the Alliance

We explore the dimensions of the Parents as Partners principle, the widely touted, but somewhat elusive construct in the literature on treating children with serious mental illness, whose poorly defined boundaries, lack of empirical grounding, and overemphasis on instrumental dimensions attenuates its usefulness as a guide for practice and research. Four major barriers to the realization of this principle are outlined, all of which may impede actualizing partnership in practice and may also inhibit the early formation of a positive clinician/parent alliance, a neglected, though key dimension of true partnership practice. The alliance, which has a long clinical and research history in psychotherapy and behavioral research, and more recently, in a variety of community-based interventions, is a precursor to active client partnership with helpers and to treatment participation, as well as therapeutic in its own right. After reviewing relevant alliance research, we close with a beginning research agenda to incorporate the alliance as an integral component of future conceptualization and research about the Parents as Partners principle.     

Classification of vowels and consonants by individuals with moderate mental retardation: development of arbitrary relations via match-to-sample training with compound stimuli.

This study explored whether an identity-matching-based stimulus equivalence procedure could be used to teach vowel and consonant stimulus classes to 2 adolescent females with moderate mental retardation. Delayed match-to-sample trials presented a compound sample stimulus consisting of printed letters and a spoken word (“vowel” or “consonant”). The correct comparison stimulus matched only one of the letters in the compound sample. Subsequently, test trials assessed whether arbitrary relations had formed among the individual stimuli from each compound sample and whether stimuli from different compound samples had merged into larger stimulus classes. Both participants acquired five-member classes of vowel and consonant stimuli, which subsequently generalized to vocal classification and to identification in the context of four-letter words. Follow-up tests showed that the generalized performances remained intact after 6 weeks. These procedures suggest an economical approach to stimulus class development.

TRAINING PEERS TO TUTOR: EVALUATION OF A TUTOR TRAINING PACKAGE FOR PRIMARY LEARNING DISABLED STUDENTS

Peer tutoring—academic instruction given by a student to a same-aged classmate—can be a cost-effective way of providing needed instruction in the typical classroom where one teacher must deal with many students of varying ability levels. This study evaluated an instructional package as a training method for increasing the use of selected tutoring behaviors by peer tutors. Nine male students, aged 7 to 9 years, from a learning disabilities resource room served as subjects; four subjects served as tutors, four as students, and one as a generalization student who was assigned to all tutors during generalization testing. Subjects were assigned to tutor-student pairs based on their performances on a pretest of the 220 Dolch Basic Sight Words, with the subjects scoring highest on the pretest serving as tutors. Each tutor worked with his assigned student throughout the study, except for pre- and posttest sessions with the generalization student. During daily sessions, tutors trained their students to recognize sight words using 10 flash cards, each with 1 of the Dolch words printed on it. Training was conducted with all four tutors in a group and was evaluated using a multiple baseline design across three classes of tutoring behaviors: Preparation Behaviors, Prompting Behaviors, and Praising Behaviors. Training consisted of: (a) verbal instructions on how to perform the tutoring behaviors; (b) charts illustrating the appropriate tutoring behaviors with stick figures; (c) role playing with each tutor with the experimenter playing the part of the student and giving feedback and verbal reinforcement to the tutor for performance of the appropriate tutoring behaviors; and (d) verbal testing of each tutor by asking him to state orally the behaviors he was to perform. Training sessions took approximately 30 minutes for each of the 3 classes of tutoring behaviors. Results showed an increased use of tutoring behaviors by tutors as a function of the instructional package. Increases in tutoring behaviors were also observed during postintervention generalization testing of tutors instructing their regular student in new subject matter (math). Data taken from pre-, mid-, and postintervention testing of the 220 Dolch Words showed an increase of identifiable sight words by both students and tutors after completing the peer tutoring program. This study demonstrates that a simple tutor training package can be employed to teach young, special education students to serve as effective tutors for their peers. In addition, the academic gains evidenced by the subjects lend positive support to the effectiveness of peer tutoring programs and specifically to the research of Dineen, Clark, and Risley (Journal of Applied Behavior Analysis, 1977, 10 , 231–238) which demonstrated the educational benefits of tutoring incurred by the tutor as well as by the student.     

Stimulus properties of conspecific behavior

Two experiments identified the conditions in which the behavior of one bird acquired discriminative control of the behavior of a second bird. The schedule-controlled behaviors of the “stimulus” bird were differentially correlated with the components of a multiple schedule according to which the pecking of an “experimental” bird produced food. In Experiment 1, three pairs of pigeons acquired a successive discrimination and two reversals with the conspecific stimuli. Experiment 2 included a control condition in which no systematic relationship existed between the conspecific stimuli and the component schedules. While differential responding during the components of the multiple schedule was again found when the conspecific stimuli were available, differential responding did not occur in the control condition. Test conditions included in the experiments indicated that (a) the differential responding was not dependent on the discriminative properties of reinforcement, (b) the pecking of the stimulus and experimental birds was temporally interrelated, (c) the visual conspecific stimuli were critical to the maintenance of the discrimination, and (d) the observed stimulus control immediately generalized to an unfamiliar conspecific.
