ALL STIMULI ARE EQUAL,BUT SOME ARE MORE EQUAL THAN OTHERS: MEASURING RELATIONAL PREFERENCES WITHIN AN EQUIVALENCE CLASS

Two experiments used post‐class formation within‐class relational assessment test performances to evaluate whether participants demonstrated preference for certain members of an equivalence class based on the type of relation that existed between class members. In Experiment 1, two 5‐node 7‐member equivalence classes, consisting entirely of nonsense syllables, were established using the simultaneous protocol. Only 1 of the 6 participants in Experiment 1 formed classes. After class formation, the effects of the different relations between stimuli were evaluated using within‐class relational assessment tests, and the 1 participant showed an absolute preference for transitive over equivalence relations, and for baseline over symmetrical relations. Experiment 2 was identical to Experiment 1, except that one of the nonsense syllable stimuli in each class was replaced by a pictorial stimulus. Under these conditions, classes were formed by 5 of 13 participants. During the relational assessment tests, the 5 participants who formed classes demonstrated almost exclusive preferences for transitive relations over equivalence relations and for trained baseline relations over symmetrical relations. Thus, this research demonstrates that the members of equivalence classes are differentially related to each other based on relational type.     

TEACHING BETWEEN-CLASS generalization OF TOY PLAY BEHAVIOR TO HANDICAPPED CHILDREN

In this study, young children with severe and moderate handicaps were taught to generalize play responses. A multiple baseline across responses design, replicated with four children, was used to assessthe effects of generalization training within four sets of toys on generalization to untrained toys from four other sets. The responses taught were unique for each set of toys. Acrossthe four participants, training to generalize within-toy sets resulted in complete between-class generalization in 11 sets, partial generalization in 3 sets, and no generalization in 2 sets. No generalization occurred to another class of toys that differed fromthe previous sets in that they produced a reaction tothe play movement (e.g., pianos). Implications for conducting research using strategies based on class interrelationships in training contexts are discussed.     

THE EFFECT OF THE AVAILABILITY OF A SIMILAR TOY ON COMPLIANCE WITH INSTRUCTIONS TO SURRENDER A TOY AMONG PRESCHOOL CHILDREN

We evaluated the effect of the availability of a similar toy on compliance with an instruction to surrender a toy among three preschool children. First, high‐preference and medium‐preference toys were identified for each participant. During the treatment evaluation, reversal designs were used to examine compliance with an instruction to surrender these toys when a toy similar to the target toy was added to the environment. The results indicated that, for two participants, the similar toy intervention increased compliance to moderate levels; a consequence‐based intervention was then added to the similar toy intervention and resulted in high levels of compliance. For the third participant, the similar toy intervention did not increase compliance. A separate consequence‐based intervention was necessary to increase compliance and to demonstrate experimental control. Copyright © 2011 John Wiley & Sons, Ltd.     

TRIAL-BASED FUNCTIONAL ANALYSIS AND FUNCTIONAL COMMUNICATION TRAINING IN AN EARLY CHILDHOOD SETTING

Problem behavior is common in early childhood special education classrooms. Functional communication training (FCT; Carr & Durand, 1985 ) may reduce problem behavior but requires identification of its function. The trial‐based functional analysis (FA) is a method that can be used to identify problem behavior function in schools. We conducted trial‐based FAs and FCT with 3 children in an early childhood special education setting. All trial‐based FAs resulted in identification of behavioral functions, and subsequent FCT led to reductions in problem behavior and increases in communication.     

一种与心理活动相关的脑电波

对14名青年进行了普通的CNV实验和无运动CNV实验。发现了一种与心理负荷解脱伴随出现的脑电波——解脱波EML。EML波不同于普通CNV后形成的Ⅴ波,不含诱发电位外源性成分和运动成分,代表心理负荷的解脱,纯属一种只与心理活动相关的脑电波。目前尚无理由将EML波视为LPC(LatePositive ComPlex)的一员。提出CNV心理因素的性质,可能是在完成同种任务时由期待、意动、动机、朝向和觉醒等多种心理因素综合构成的心理负荷加重。本工作采取了离线式排除伪迹程序,在数据处理上做出了总平均图(Grand Average Records)。     

USING LAG SCHEDULES TO INCREASE TOY PLAY VARIABILITY FOR CHILDREN WITH INTELLECTUAL DISABILITIES

Relatively few studies have evaluated procedures for increasing play skills in children with intellectual disabilities. To address this limitation, this study evaluated the extent to which lag schedules increased novel toy play responses for three children who exhibited little or no appropriate toy play. Results show that the lag 1 schedule increased toy play variability for all three participants and the lag 2 schedule produced very little additional variability for the two participants exposed to this condition. The results of a social validity assessment suggest that classroom paraprofessionals (i) perceived the participants' toy play as typical and (ii) were satisfied with the outcomes produced by the lag schedules. We discuss the clinical implications and the potential limitations of the findings. Copyright © 2014 John Wiley & Sons, Ltd.     

COMMUNICATION FACTORS RELATED TO CLOSER INTERNATIONAL TIES

The question of what promotes closer ties between nations has long been central to the study of intercultural communication. This research develops and tests a model that specifies three factors drawn from social distance and systems perspectives that are posited to have an influence on the desire for closer ties between the U.S. and Mexico. Each of the factors, perceptions of homophily, shared interests, and threats, have previously been identified as occupying central positions in the development of international relationships. The sample used to test the model was drawn from eight elite occupational groups within Mexican urban centers (N = 800). The results were supportive of the model, with quite acceptable goodness of fit measures, with a high level of variance accounted for in the dependent variable, and with support for the paths between exogenous and endogenous variables as predicted in the model.     

PROMOTING AUTISTIC CHILDREN'S PEER INTERACTION IN AN INTEGRATED EARLY CHILDHOOD SETTING USING AFFECTION ACTIVITIES

Group affection activities were used to increase the interaction of three autistic children with their nonhandicapped peers in an integrated early childhood setting. Peer interaction increased during free play when the affection activities were conducted, but not when similar activities without the affection component were used. This interaction included initiations by both the autistic and nonhandicapped children, with reciprocal interactions occurring more frequently with nonhandicapped peers who had participated in the affection activities.     

UNIVERSITY STUDENT READING PREFERENCES IN RELATION TO THE BIG FIVE PERSONALITY DIMENSIONS

In this study 251 Australian university students, with a mean age of 26.46, indicated their preference for different types of reading material. A subset of 136 participants additionally reported how many hours per week they typically engage in recreational reading and non-recreational reading, indicated their motivation for recreational reading, completed a Big Five personality inventory, and kept a week-long reading log in which they recorded daily their recreational reading of different types of materials. A principal components analysis showed that reading preferences grouped into eight content areas. A set correlation analysis showed that overall the Big Five personality dimensions predicted reading preferences. Openness and conscientiousness in particular were good predictors of four specific types of content preferences. Preference for a certain type of material tended to predict time spent reading that material as reported in the week-long reading log. Further, the Big Five personality dimensions together predicted total amount of recreational reading, amount of reading of favorite material, and amount of non-recreational reading.     

TEACHING EARLY READING SKILLS TO CHILDREN WITH AUTISM USING MIMIOSPROUT EARLY READING

A number of studies have demonstrated positive outcomes for typical learners from the internet‐based reading program, MimioSprout® Early Reading (MER). In the present study, a preliminary evaluation of MER was conducted with four children with autism who attended an applied behavior analysis educational program in a school setting. The primary aim was to investigate whether it would be feasible to use MER with children with autism and whether any adaptations to the standard teaching procedure would be needed. A secondary aim was to investigate whether completing MER would improve early reading skills. When additional discrete‐trial table top activities were designed to supplement each child's progress, every child was able to complete all 80 lessons and showed similar correct performance to that reported for typically developing learners. Results from a standardized test of reading ability showed an improvement in word recognition reading age for all children from 14 months to more than three years over the 14 weeks of teaching. A follow‐up test showed that gains were maintained eight weeks after the end of the intervention. MER can be successfully used with children with autism and can improve their early reading skills.

THE VALIDATION OF PROCEDURES TO ASSESS PREVOCATIONAL TASK PREFERENCES IN RETARDED ADULTS

Three severely retarded young adults between the ages of 19 and 21 years participated in a prevocational training program, and worked regularly on six different tasks during the scheduled six-hour day. The study attempted to assess each subject's preferences for the six tasks: collating, stuffing, sorting, pulley assembly, flour-sifter assembly, and circuit-board stuffing. In Phase I, the procedure consisted of randomly pairing each task with all other tasks in a two-choice situation that required the subjects to select one task from each pair combination to work for a seven-minute period. The selection procedure consisted of presenting two representative task objects on a tray and requesting the subject to pick up one object and place it on the work table. The object selected represented the task worked for that period. The 15 possible pair combinations were presented randomly every two days for a period of 34 days to determine the preferences. During the validation phase (Phase II), each subject's least- and most-preferred tasks were paired separately with moderately-preferred tasks. As expected, these manipulations confirmed the baseline data, as choices for the moderately-preferred tasks decreased when consistently paired with the preferred tasks and increased when consistently paired with the least-preferred tasks.     

FACTORS RELATED TO SUCCESS IN AN MDTA PROGRAM

A study was undertaken to attempt to relate selected defined factors to success in a Manpower Development Training Center program. Subjects were disadvantaged or culturally deprived adults who were referred to a nurse aide-orderly training course that consisted of both vocational and remedial education phases. Factors studied were an evaluation by the referring counselor in the stated interest of an individual taking the training, previous employment history (compiled by both type and duration), formal educational level, age when completing the course, expressed attitudes toward the course while enrolled, and aptitude test results.     

VARIABLES RELATED TO BREAST SELF-EXAMINATION: Model Generation

Using a prospective design, variables from several relevant social psychological theories that would predict breast self-examination were identified. The participants included a probability sample of 362 women who were 35 or older. Instruments were tested for validity and reliability. Data were collected from each participant twice, 1 year apart, using an in-person interview for Time 1 and a telephone interview for Time 2. Results of standardized path coefficients (beta) indicated that breast self-examination (BSE) at Time 2 was directly related to BSE at Time 1 (.76). Indirect paths for susceptibility (.40), health motivation (.46), and barriers (-.54) were identified. All paths mentioned were significant (p5.01). Findings have implications for interventions to increase BSE in women 35 and older.     

VOCABULARY: NEEDED IF MORE CHILDREN ARE TO READ WELL

Vocabulary has long been recognized as a strong determinant of reading success. Despite the importance of vocabulary knowledge, very little information is available about effective strategies for vocabulary instruction in elementary grades and there is a paucity of data on the relative merits of the different programs that are designed to promote vocabulary growth in elementary children. Available information indicates that, until they reach about grade three, children’s vocabulary knowledge is largely determined by informal factors such as parental interaction and other incidental sources such as the TV. In this article, I will address the following topics: (a) individual differences in vocabulary acquisition, (b) the amount of vocabulary needed for successful learning, (c) the predictable sequence of vocabulary acquisition, (d) the need for direct instruction for vocabulary growth, and (e) promising methods for promoting vocabulary knowledge.
