Conceptualization and Development of the Behavior Analysis Programs at the Florida Institute of Technology

We describe the conceptualization and development of the Behavior Analysis programs at the Florida Institute of Technology (Florida Tech). From its beginnings as a small master’s program in applied behavior analysis (ABA), the Behavior Analysis programs at Florida Tech have now grown to include three Master of Science programs across two campuses, a Ph.D. program in Behavior Analysis, an undergraduate degree (B.A.) in ABA, an online certificate program that has attracted students internationally, and a hybrid (live and online) Master of Arts in Professional Behavior Analysis program at several sites around the USA. These programs are now housed in the first ever School of Behavior Analysis at a Tier 1, nationally ranked private university.     

猜谜作业中的ERP效应：基于催化范式的证据

运用ERP技术对个体猜谜任务下的顿悟和无顿悟的情况进行探索。结果发现,在300ms-500ms内,有顿悟比无顿悟引发了更负的N300-500成分,激活了大部分脑区;在600ms-1100ms内,有顿悟比无顿悟引发了更正的P600-1100成分,在中央区显示了最强激活。结果表明,N300-500可能反映了定势破除中的认知冲突,P600-1100可能反映了新异联系的形成。     

Dichhaptic hand-order effects with verbal and nonverbal tactile stimulation

The palms of normal right-handed subjects were stimulated dichhaptically, i.e., with competing, bimanually presented tactile stimuli consisting of pairs of letters, pairs of digits, or pairs of line orientations. The subjects were required to identify both stimuli in a particular order, and order of report was compared between hands and across stimulus materials. Results indicated right-hand superiority for letters and left-hand superiority for lines; no hand differences occurred for digits. However, observed differences between hands appeared with second reports only, suggesting that measures of tactile storage are more sensitive to laterality differences than measures closer in time to actual stimulation.     

A developmental perspective on reading dysfunction: Accuracy and rate criteria in the subtyping of dyslexic children

Children referred with specific reading dysfunction were subtyped as accuracy disabled or rate disabled according to criteria developed from an information processing model of reading skill. Multiple measures of oral and written language development were compared for two subtyped samples matched on age, sex, and IQ. The two samples were comparable in reading fluency, reading comprehension, word knowledge, and word retrieval functions. Accuracy disabled readers demonstrated inferior decoding and spelling skills. The accuracy disabled sample proved deficient in their understanding of oral language structure and in their ability to associate unfamiliar pseudowords and novel symbols in a task designed to simulate some of the learning involved in initial reading acquisition. It was suggested that these two samples of disabled readers may be best described with respect to their relative standing along a theoretical continuum of normal reading development.     

The Boston Naming Test: Norm data and cue utilization in a sample of normal 6- and 7-year-old children

The object-naming abilities of 83 normal children were examined using the Boston Naming Test developed by E. Kaplan, H. Goodglass, and S. Weintraub (1976, The Boston Naming Test (experimental edition), unpublished test, Veterans Hospital, Boston, Massachusetts). There is currently a lack of available norms for this instrument, especially for populations of younger children. Cue utilization in this sample is explored and attention is focused upon possible gender differences in naming performance and cue strategies. Seven summary scores derived from the test are presented in this report. Results indicate that the Boston Naming Test can discriminate within a normal population sample of young children and provides a relatively normal distribution for six of seven derived scores. Boys were found to have a significantly greater number of items correctly named but no gender differences in cue utilization were evident. A major proportion of the children in this sample of 6- and 7-year-olds used phonological cues almost exclusively, rather than semantic cues also provided. Cue use was not related to age or spontaneously given responses, and none of the children were found to be highly proficient at using both types of cues.     

Developing referential communication skills: The interaction of role-switching and difference rule training

Although both substantive knowledge and enabling skills are important to the development of referential communication, deficits in procedural knowledge may account for a significant portion of preschoolers' communicative failures. The results of this training study with 5-year-olds revealed that they lack two major procedural skills. They do not know the importance of differentiating referents from nonreferents. They also are unaware that the speaking and listening roles are, at least in part, complementary; that is, certain rules are applicable to both. After training which provided specific instruction on the nature of informative messages (in either the speaking or listening mode, but not both) and role-switching experience, performance improved both on tasks in the trained and in the nontrained modalities. Discussion focuses on both the practical implications and the theoretical significance of these results.     

Self-presentation and drive in social facilitation

Social facilitation refers to cases in which the presence of others increases the probability of certain responses on the part of an independently operating individual. Drive theory attributes these effects to an unconscious facilitation of dominant responses, as defined by Hull-Spence learning theory. Self-presentation explanations posit changes in motivation and cognitive strategies that result from an increased concern with favorable private and public images. The present paper reviews evidence and presents an experiment indicating both points of view are valid, but that neither perspective by itself can account for all relevant data.
