We tested the effect of multiple exemplar instruction on the transfer of stimulus function for unfamiliar pictures across listener responses (i.e., matching and pointing) and speaker responses (i.e., pure tacts and impure tacts). Three preschool students, who were 3- and 4-year-old males and did not have the listener to speaker component of the naming repertoire, participated in the experiment. The dependent variable was numbers of correct responses to probe trials of both untaught listener responses (“point to__”) and speaker responses (tact and impure tacts) following mastery of matching responses for two sets of five unfamiliar pictures (Set 1 and Set 3). After each participant mastered matching (e.g., “match Labrador”) for Set 1 pictures they were probed on the three untaught responses to Set 1 words. That is, they were asked to point to Labrador, tact the picture of Labrador, and respond to the picture of a Labrador and the question “What is this?” Next, the participants were taught mastery of all four types of responses using MEI for a second set of five pictures (Set 2) and probed again on the 3 untaught Set 1 responses. Finally, matching responses were taught to mastery for a novel set of pictures (Set 3) and then probed on the three untaught responses. The results showed that untaught speaker responses emerged at 60% to 85% for two participants, and 40%–70% for one participant. We discuss the role of instructional history in the development of the listener to speaker component of naming.  相似文献

Naming is a verbal developmental capability and cusp that allows children to acquire listener and speaker functions without direct instruction (e.g., incidental learning of words for objects). We screened 19 typically developing 2- and 3-year-old children for the presence of Naming for 3-dimensional objects. All 9 3-year-olds had Naming, and 8 of 10 2-year-olds lacked Naming. For the 2-year-old children who lacked Naming, we used multiple-probe designs (2 groups of 4 children) to test the effect of multiple exemplar instruction (MEI) across speaker and listener responses on the emergence of Naming. Prior to the MEI, the children could not emit untaught listener or speaker responses following match-to-sample instruction with novel stimuli, during which they had heard the experimenter tact the stimuli. After MEI with a different set of novel stimuli, the children emitted listener and speaker responses when probed with the original stimuli, in the absence of any further instruction with those stimuli. Seven of 8 children acquired the speaker and listener responses of Naming at 83% to 100% accuracy. We discuss the basic and applied science implications.  相似文献

We report experiments using time-lagged pre- and postintervention designs with (a) 4 first graders with learning delays, and (b) a systematic replication with 3 preschoolers with learning delays. Both experiments tested the effects of multiple exemplar instructional procedures (MEI) on the emergence of untaught past tense emission of novel regular verbs (e.g., jumped derived from jump) and grammatically inaccurate but experimentally correct usage of irregular verbs (e.g., singed derived from sing). Prior to the MEI, none of the children could produce regular or irregular past tense forms to pictures that provided simulated contexts (pictures with backgrounds for past and present tense). MEI provided across the picture contexts for past and present tense used separate training sets of verbs to teach children to form regular past tense. After either 1 or 2 MEI training sets, the children emitted accurate past tense forms of the untaught regular and inaccurate, but experimentally correct irregular verbs. These findings provided an instructional history that resulted in the children''s acquisition of past tense for untaught regular past tense verbs and “creative” errors with irregular tenses. Results are discussed in terms of the research on experimentally induced sources for novel verbal behavior and related interpretations.  相似文献

We evaluated the facilitative effects of multiple exemplar training (MET) on the establishment of derived tact relations in typically developing children. A multiple-probe design across stimulus sets was implemented to introduce MET. Participants were first taught to conditionally relate dictated names in English to their corresponding objects (listener behavior; A-B relations), followed by tests for derived tacts (B-A relations). If participants failed these tests, MET was implemented whereby tact relations were explicitly taught with novel stimulus sets, followed by test probes with the original training set. MET continued with novel stimuli until participants met criterion for the emergence of derived tact relations or after exposure to three MET sets. Results indicated failed tests for tact relations following direct training in listener relations, and marked improvements in derived tact relations following MET across all participants.  相似文献

We tested the effect of multiple exemplar instruction (MEI) on acquisition of joint spelling responses, vocal to written and vice versa, for three sets of five words by four kindergarteners with language delays using a delayed multiple probe design. First, students were taught to spell Set 1 as either vocal or written responses (two vocal and two written) and probed on untaught responses. Next students were taught Set 2 using MEI (i.e., alternating responses) and again probed untaught responses for Set 1. Finally, Set 3 was taught in a single response and students were probed on untaught responses. Two students spelled none of Set 1 untaught responses before MEI, while two spelled the words at 60% accuracy or 10% accuracy. After MEI on Set 2, all students spelled untaught responses for Set 1 at 80% to 100% accuracy and Set 3 at 80% to 100% accuracy. The MEI resulted in joint stimulus function such that formerly independent responses came under the same stimulus control. We replicated these results with four other kindergartners with autism who performed academically above their typically developing peers. The results are discussed in terms of Skinner''s treatment of the independence of the two verbal operants.  相似文献

We evaluated the effects of multiple exemplar instruction (MEI) on the relation between listener and intraverbal categorization repertoires of six typically developing preschool-age children using a nonconcurrent multiple-probe design across participants. After failing to emit intraverbal categorization responses following listener categorization training, participants were exposed to MEI in the form of alternating response forms (listener and intraverbal) during categorization training with novel stimulus sets. For two participants for whom there was some evidence of emergent intraverbal responding, responding was variable. For the remaining four participants, 32 to 99 MEI trial blocks produced minimal improvement in responding or no emergent responding at all. The results are discussed in terms of Skinner’s analysis of verbal behavior and naming theory.  相似文献

We report 2 experiments that tested the effects of multiple exemplar instruction (MEI) across training sets on the emergence of productive autoclitic frames (suffixes) for 6 preschoolers with and without language-based disabilities. We implemented multiple exemplar tact instruction with subsets of stimuli whose "names" contained the suffix "-er" denoting the comparative form of adjectives. Subsets of stimuli included regular, irregular, and contrived tacts containing the target relational autoclitic frame in order to determine if our MEI procedure would induce the abstraction of the frame across all stimulus sets. In the second experiment, additional tasks were introduced to the participants to control for a possible sequence effect. A nonconcurrent multiple probe design was used to evaluate the functional relation between MEI and emergence of untaught tact responses containing the comparative adjective "-er." The results of both experiments showed relations between MEI and novel, untaught tact responses containing the target autoclitic frame; the second experiment showing a functional relation. The results are discussed in terms of environmental sources for productive verbal behavior.  相似文献

Skinner''s (1957) analysis of verbal behavior has been the subject of much controversy in recent years. While criticism has historically come from outside the field of behavior analysis, there are now well-articulated arguments against Skinner''s analysis of verbal behavior from within the field as well. Recently, advocates of Skinner''s analysis have attempted to respond to the critiques, particularly to those regarding Skinner''s definition of verbal behavior articulated by proponents of relational frame theory. Specifically, it has been suggested that talk about definitions equates to making the essentialist error. This paper provides an overview of these issues in the context of understanding the role of constructs in science more generally. It will be argued that definitions are central to scientific progress, and are not only relevant to a functional analysis, but a central prerequisite to the pursuit of such an analysis.  相似文献

ABSTRACT

Culture and tradition influence behavior. Multiple-partner and concurrent relationships are held responsible for the increase of HIV infection in Sub-Saharan Africa. A contextualized “theory of planned behavior” is used in this article to identify predictors of intention to practice monogamy. A mixed method design using qualitative data from focus groups, stories, and a survey is analyzed for quantitative data. The qualitative data add to the behavioral beliefs a sociocultural belief domain, as well as attitudes and subjective norms. Perceived behavioral control predicts the intention to practice monogamy. Adolescents show a tendency toward having more than one sexual partner. The normative beliefs and the sociocultural beliefs also predict intentions, while hedonistic beliefs and partner’s reaction do not. In contextualizing theory-based interventions, it is important to draw from stories and the language that circulate in a community about a given behavior. More studies are needed on ways to combine qualitative approaches with quantitative approaches to inform the development of theory-based, culturally appropriate, and context-specific intervention strategies to reduce the risk of HIV.  相似文献

As transcendent technologies, information communication technologies (ICTs) exist beyond the divergent equivalence of human categories of difference such as race, gender, and class, as well as operating outside traditional binary oppositions such as good/bad, love/hate, and rational/irrational. While a material grounding in earlier forms of embodied social experience remains a necessary prerequisite of interaction with virtual systems, a vast collection of technological applications now exhibit some degree of agency as they interact with humans and their environment. This development has enormous consequences for human life, human flourishing, and social organisation, raising significant ethical concerns relevant to public and policy debates. It is, therefore, pertinent to explore key epistemological questions relating to the radical and accelerated remapping of the limits of what it now means to be human. While this article does not purport to offer a pragmatic solution, it constitutes an interdisciplinary conceptual platform from which to consider the nature of the evolving human-nonhuman-machine relationship and the possible implications for humanity, civilisation, and other forms of social organisation in the modern hypermediated world. It is suggested that, by reflecting on the various representations of contemporary technoculture and biotechnology from the perspective of the arts and humanities, it may be possible to isolate those important questions which relate to subjectivity, ethics, community, and social transformation in order to prepare the groundwork for a comprehensive and critical theory of technology.  相似文献
