The Emergence of the Listener to Speaker Component of Naming in Children as a Function of Multiple Exemplar Instruction

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.     

Evaluating the Effectiveness of the Stimulus Pairing Observation Procedure and Multiple Exemplar Instruction on Tact and Listener Responses in Children with Autism

The Analysis of Verbal Behavior - The stimulus pairing observation procedure (SPOP) combined with multiple exemplar instruction (MEI) has been shown to be effective with typically developing...     

Establishing Naming in Typically Developing Two-Year-Old Children as a Function of Multiple Exemplar Speaker and Listener Experiences

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.     

The Emergence of Autoclitic Frames in Atypically and Typically Developing Children as a Function of Multiple Exemplar Instruction

In two experiments, we tested the effect of multiple exemplar instruction (MEI) for training sets on the emergence of autoclitic frames for spatial relations for novel tacts and mands. In Experiment 1, we used a replicated pre- and post-intervention probe design with four students with significant learning disabilities to test for acquisition of four autoclitic frames with novel tacts and mands before and after MEI. The untaught topographies emerged for all participants. In Experiment 2, we used a multiple probe design to test the effects of the MEI procedures on the same responses in four typically developing, bilingual students. The novel usage emerged for all participants. In the latter experiment, the children demonstrated untaught usage of mand or tact frames regardless of whether they were taught to respond in either listener or speaker functions alone or across listener and speaker functions. The findings are discussed in terms of the role of MEI in the formation of abstractions.     

Novel Dictation and Intraverbal Responses as a Function of a Multiple Exemplar Instructional History

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.     

The Effects of Multiple Exemplar Instruction on the Relation Between Listener and Intraverbal Categorization Repertoires

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.     

Effects of Multiple Exemplar Training on the Emergence of Derived Relations in Preschool Children Learning a Second Language

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.     

How Kids Learn to Say the Darnedest Things: The Effect of Multiple Exemplar Instruction on the Emergence of Novel Verb Usage

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.     

The Presence of the Defensive Function as a Predictor of Heterosexual College Students' Affective Responses Toward Gay Men and Lesbians

The intent of this study was to isolate and examine the presence of the Defensive Attitudinal Function as a predictor of affective responses of 70 heterosexual college students toward ay men and lesbians. Forty-four percent of the subjects were classified as Defensive Function Present (DFP) and 55% as Defensive Function Absent (DFA). The results indicate that DFP individuals exhibit significantly higher levels of homophobia than do DFA individuals. All subjects exhibited significantly lower levels of homophobia after viewing an intervention message. This result suggests that individuals for whom the defensive function is present may not be as resistant to attitude change as previously theorized.     

Victimization of Non-Custodial Parents,Grandparents, and Children as a Function of Sole Custody

While the country has seen an increase in joint custody arrangements over the last two decades, many states still exercise a de-facto presumption of sole custody for one parent and "visitation" status for the other. However, during the last several years, evidence has mounted that sole custody/visitation arrangements create unnecessary and unwarranted victimization of non-custodial parents,grandparents, and children at the hands of the custodial parent. The purpose of this paper is to present the evidence on this victimization, in concert with the evidence from selected advocacy group publications for non-custodial parents, in an effort to expand the current investigations to a broader ecologically based perspective which includes all emotionally relevant extended family members. Methodological concerns and directions for future research will be highlighted.     

The Use of Multiple Family Marathon as a Teaching Device

This paper discusses the rationale and methods for using a multiple family marathon as a teaching device in the context of an intensive group-supervision family therapy training program conducted by the authors. Procedures used in the marathon are described, as well as how the concept stimulates increased focus on issues common to family therapy and broadens the experience of the students. The effects of the marathon on the students' views of their therapy families and of themselves as family therapists are explored.     

The Social Construction of Abducted Children as a Social Problem

Using the theoretical framework developed by Spector and Kitsuse (1973; 1977), this paper describes the development of the issue of abducted children as a social problem. Analysis of this particular case suggests theoretical refinements for the social constructionist perspective. It is argued that the concept of a "valence issue" could be used to differentiate between the natural histories of substantively different kinds of social problems.     

The Role of Joint Control in the Manded Selection Responses of Both Vocal and Non-vocal Children with Autism

In the present study, joint-control training was applied when teaching manded selection responses to children with autism. Four vocal children with autism participated in the first experiment, two males (ages seven and eight) and two females (ages seven and nine). The results showed that it was only after object-word naming was trained under joint control that the symmetrical performance of manded selection responses appeared with no additional training. Four non-vocal children with autism participated in the second experiment, two males (ages six and seven), and two females (ages twelve and thirteen). These results also showed that it was only after the joint tact/self-mimetic/sequelic control training that the symmetrical performance of manded selection responses appeared with no additional training.     

An fMRI Study of Responses to Sexual Stimuli as a Function of Gender and Sensation Seeking: A Preliminary Analysis

Although sexual cues produce stronger neural activation in men than in women, mechanisms underlying this differential response are unclear. We examined the relationship of sensation seeking and the brain’s response to sexual stimuli across gender in 27 subjects (14 men, M = 25.2 years, SD = 3.6, 85.2% Caucasian) who underwent functional magnetic resonance imaging (fMRI) while viewing sexual and nonsexual images. Whole-brain corrected significant clusters of regional activation were extracted and associated with gender, sensation seeking, and sexual behaviors. Men responded more to sexual than nonsexual images in the anterior cingulate/medial prefrontal cortex (ACC/mPFC), anterior insula/lateral orbitofrontal cortex, bilateral amygdala, and occipital regions. Sensation seeking related positively to ACC/mPFC (r = 0.65, p = 0.01) and left amygdala (r = 0.66, p = 0.01) response in men alone, with both of these correlations being significantly larger in men than in women (ps < 0.03). The relationship between brain responses and self-reported high-risk and low-risk sexual behaviors showed interesting, albeit nonsignificant, gender-specific trends. These findings suggest the relationship between sexual responsivity, sensation seeking, and sexual behavior is gender specific. This study indicates a need to identify the gender-specific mechanisms that underlie sexual responsivity and behaviors. In addition, it demonstrates that the nature of stimuli used to induce positive mood in imaging and other studies should be carefully considered.     

The Limits of Working with Children Cards in Protecting Children

Abstract

In 2006 Western Australia passed legislation that introduced a system to check criminal records and issue permits to those who wish to work with children. In 2007, the legislation was described by the minister responsible as a “powerful system that would prevent harm to children”. This paper explores that system and identifies limits to its effectiveness. The paper concluded that unless the system's limits are fully appreciated there is a possibility of a paradoxical outcome, whereby children's lives will be less safe. It also raises the question of whether in the area of record checking a national approach is not preferable to each state and territory developing its own system.     

Generalized Reflexive Responding and Cross-Modal Tactile Transfer of Stimulus Function in Children with Autism

We sought to evaluate the efficacy of successive matching training for establishing generalized reflexive matching across 4 children with autism. In Experiment 1, differential reinforcement with delay fading was efficacious in establishing “yes” and “no” matching and nonmatching responses in 2 participants when 2 identical or nonidentical picture stimuli were presented. In addition, emergent visual–visual reflexive relational responses were observed using novel picture stimuli in a transfer test phase. In Experiment 2, differential reinforcement alone was efficacious in establishing matching and nonmatching responses in the other 2 participants when 2 identical or nonidentical objects were presented. Transfer to identical objects presented through touch (i.e., tactile discrimination) was additionally observed for both participants. Procedures in the study were adapted from the PEAK Relational Training System to aid in clinical replication, and the translational results have implications for language training with individuals with autism.     

Contextual Dimensions in Attitudes as a Function of Group-Originating Identities

Abstract

Rokeach's theory of attitude expression (that persons maintain both attitudes toward situations and toward objects or classes of objects) was redefined to make context and objects dimensions of attitude. This analytical distinction was empirically reproduced within a symbolic interaction framework. The hypothesis that persons including a higher number of group referents in verbalized self-identity are more likely to rely on the contextual dimension when evaluating an object-in-a-situation than are respondents including a lesser number was then tested. Instruments used were the Twenty Statements Test and a scale of favorability composed of five semantic differential items. Analysis of variance and regression techniques provided support both for Rokeach's model of attitudes as well as for the hypothesis.     

The Exploration of Role Induction as a Potential Method for Improving Men's Perceptions of Career Counseling

The authors explored the influence of role induction on men's perceptions of career counseling and attitudes toward seeking professional help. Two separate role inductions were presented to 268 male college students; the first discussed holistic career counseling, and the second integrated a discussion of male gender role socialization. Results demonstrated that participants who viewed the holistic role induction reported greater valuing of career counseling when compared with a control group. However, results indicated no difference in perceptions of career counseling between a holistic career counseling role induction and one that included socialized male perceptions of counseling.     

The Estimation of Task Performance and Reward Recommendations as a Function of Status Ranks

Abstract

A recurrent concern among social psychologists is to determine how individuals react to status ranks of others. This study presented 144 college students with a hypothetical situation and asked them to recommend an reward allocation to a person in the situation and to estimate that person's future task performance. Subjects were presented with information about either a diffuse status characteristic (educational level), or specific status characteristic with task relevance (performance on a related task), or both for an individual in comparison to a standard comparison other. When information was available on only one status rank, rewards were allocated and task performance estimated consistent with the single status rank. When information about both status ranks were available, specific status significantly affected both the reward distribution and performance expectations, while diffuse status significantly affected the reward distribution and had a marginally significant effect on performance expectations. The results are discussed in terms of status expectancy theory (Berger et al.), Kimberly's modification and extension of that approach, and equity theory (Adams).
