Effects of mand-tact versus tact-only training on the acquisition of tacts

We sought to replicate and extend Carroll and Hesse's (1987) study of the acquisition of tacts by including participants with and without developmental disabilities. As in Carroll and Hesse, the present results showed that mand-tact training, rather than tact-only training, led to more rapid acquisition of tacts. Tacting on follow-up tests did not differ. In addition, our results show that mand-tact training established both verbal operants involved about as rapidly as tact-only training established only one verbal operant. DESCRIPTORS: verbal behavior, tact acquisition, mand-tact training, tact-only training, follow-up     

Inspection time and the relationship among elementary cognitive tasks, general intelligence, and specific cognitive abilities

The relationship between inspection time (IT) and paper-and-pencil tests of cognitive ability is well documented. However, the extent to which IT relates to cognitive ability through general intelligence or through group factors such as performance has not been fully addressed. Another unresolved issue is whether IT relates to psychometric intelligence independent from other elementary cognitive tasks. The current study examined these issues in a sample of 6–13-year-old twins drawn from the Western Reserve Twin Project (WRTP) (n=568 participants). Analyses suggest that IT and other elementary tasks predict general intelligence. IT also predicts Performance ability while other elementary tasks do not. Furthermore, IT contributes variance to cognitive ability independent from other elementary tasks. These suggest that multiple indices of elementary cognitive ability are necessary to fully understand their relationship with complex psychometric measures.     

FUNCTIONAL ANALYSIS AND TREATMENT OF INAPPROPRIATE VERBAL BEHAVIOR

The present study examined the possible function of inappropriate verbal behavior of an adult man who had been diagnosed with both mental retardation and psychosis. Results of a functional analysis indicated that inappropriate verbal utterances were maintained by attention. An intervention consisting of the differential reinforcement of appropriate verbal behavior effectively reduced the inappropriate behavior.     

高述情障碍者的情绪图式特征

采用混合实验设计,以情绪词和情绪图片为实验材料,选取不同述情障碍得分的大学生为被试,通过三个实验考察了高述情障碍者的情绪图式特征。研究结果发现：（1）高述情障碍组被试对情绪词的效价判断反应时显著长于低述情障碍组,述情障碍各维度得分均与情绪词的效价判断反应时呈显著正相关;（2）高述情障碍组被试对情绪图片的效价判断反应时与低述情障碍组相比差异不显著;（3）高述情障碍组被试情绪图式联结所需反应时显著长于低述情障碍组,情感描述困难与情绪图式联结所需反应时之间相关显著。研究结论如下：高述情障碍者存在情绪语言图式和参考性链接上的缺陷,而在情绪意象上并不存在积极/消极区分能力方面的缺陷     

Projective identification: A theoretical investigation of the concept starting from ’Notes on some schizoid mechanisms’1

This paper submits passages from four papers‐‘Notes on some schizoid mechanisms’ (Klein); ‘On identification’ (Klein); ‘Analysis of a schizophrenic state with depersonalization’ (Rosenfeld); and ‘Remarks on the relation of male homosexuality to paranoia, paranoid anxiety and narcissism’ (Rosenfeld)‐to a critical reading, enabling the theoretical premises which have produced the current, differing views on projective identification to be traced. These views revolve both around the role assigned to identification in the process and around the meaning of the expression‘to identify oneself with’ which in ‘On identification’ goes from ‘to feel similar to, or identical to the other’ to ‘to take another person as a model’. This legitimizes the inclusion of very different phenomena into the concept of projective identification. The author describes some uses of the term ‘projective identification’ and proposes the hypothesis that the process constitutes a way for managing otherness and the separateness of the object (be it external or internal, real or imaginary) that can compromise its reality to a greater or lesser degree. Covering a large set of phenomena, the author poses the question of whether it is useful to retain the term ‘projective identification’. She proposes an answer in the last part of the paper.     

An evaluation of intraverbal training to generate socially appropriate responses to novel questions

Four preschool children (with and without disabilities), who often responded inappropriately to questions, participated in the current study. Pretest results were used to create sets of questions that the children either did or did not answer correctly (i.e., known and unknown questions). We then sequentially taught two different responses to a subset of unknown questions: (a) "I don't know" (IDK), and (b) "I don't know, please tell me" (IDKPTM). Results showed that following acquisition with the target set, both responses generalized across questions and teachers for all participants. Following IDK training, some undesirable generalization of IDK to known questions occurred for 3 participants. Training of IDKPTM with the addition of a restricted reinforcement contingency was sufficient to establish correct answers to a portion of previously unknown questions. The importance of teaching generalized responses that enable the acquisition of novel intraverbals is discussed.     

Naming and categorization in young children: v. manual sign training

Following pre-training with everyday objects, 8 children aged from 2 to 4 years learned to produce one manual sign (fists placed one above the other, in front of body) to one stimulus and an alternative manual sign (shoulders touched with ipsilateral hands) to the other stimulus, with each of three pairs of different arbitrary wooden shapes (Set 1). The six stimuli then were presented in category match-to-sample tests, which all subjects passed. Three of the children were next trained to produce the manual signs (denoted as fist/shoulder) for an additional six arbitrary stimuli, Set 2. All 3 children went on to pass category match-to-sample tests for Set 2, and for Set 1 and Set 2 combined. In the final experimental phase, 2 of the children were trained, for one of the six stimulus pairs, to produce the vocal tact "zag" to one stimulus and "vek" to the other. Both children showed category transfer of these vocalizations in test trials with each of the remaining five stimulus pairs, and all the stimuli combined in a 12-stimulus array. In line with Horne and Lowe's (1996) naming account, manual sign naming was found to be as effective as vocal naming in establishing arbitrary stimulus categorization, measured in terms of category sorting and transfer of function. The findings also have implications for the training of verbal repertoires in people with learning disabilities.     

The Influence of Bloomfield's Linguistics on Skinner

Bloomfield''s “Linguistics as a Science” (1930/1970), Language (1933/1961), and “Language or Ideas?” (1936a/1970), and Skinner''s Verbal Behavior (1957) and Science and Human Behavior (1953) were analyzed in regard to their respective perspectives on science and scientific method, the verbal episode, meaning, and subject matter. Similarities between the two authors were found. In particular both asserted that (a) the study of language must be carried out through the methods of science; (b) the main function of language is to produce practical effects on the world through the mediation of a listener; and (c) a physicalist conception of meaning. Their differences concern the subject matter of their disciplines and their use of different models for the analysis of behavior. Bloomfield''s linguistics and Skinner''s functional analysis of verbal behavior are complementary approaches to language.     

An Optimized Design of Choice Experiments: A New Approach for Studying Decision Behavior in Choice Task Experiments

In this paper, we present a new approach for the optimal experimental design problem of generating diagnostic choice tasks, where the respondent's decision strategy can be unambiguously deduced from the observed choice. In this new approach, we applied a genetic algorithm that creates a one‐to‐one correspondence between a set of predefined decision strategies and the alternatives of the choice task; it also manipulates the characteristics of the choice tasks. In addition, this new approach takes into account the measurement errors that can occur when the preferences of the decision makers are being measured. The proposed genetic algorithm is capable of generating diagnostic choice tasks even when the search space of possible choice tasks is very large. As proof‐of‐concept, we used this novel approach to generate respondent‐specific choice tasks with either low or high context‐based complexity that we operationalize by the similarity of alternatives and the conflict between alternatives. We find in an experiment that an increase in the similarity of the alternatives and an increase in the number of conflicts within the choice task lead to an increased use of non‐compensatory strategies and a decreased use of compensatory decision strategies. In contrast, the size of the choice tasks, measured by the number of attributes and alternatives, only weakly influences the strategy selection. Copyright © 2014 John Wiley & Sons, Ltd.
