The use of structured learning therapy and transfer programming with disruptive adolescents in a school setting

In behavior change literature, little attention has been paid to the systematic study of variables affecting transfer of training. The present study employed a skill-training method known as Structured Learning Therapy (SLT) for the dual purpose of testing the effectiveness of this method and to identify variables that will promote transfer of training. Forty-three disruptive male adolescents were assigned to three experimental and two control conditions. One experimental group received SLT plus an additional transfer-enhancing procedure referred to as Transfer Programming (TP) which consisted of in vivo practice of treatment gains and peer reinforcement. Another group received only SLT, and a third group received only TP. One control group received only brief instructions pertaining to the nature of the skill, while the second group served as an attention control. Consistent with predictions, the results were that the two groups receiving the SLT performed significantly better than the three groups not receiving SLT on all dependent measures at posttest. These differences generally maintained at follow-up. Contrary to expectations, the implementation of TP did not prove to promote transfer of training beyond that found with SLT alone.     

Discrimination learning and stimulus generalization by impulsive and reflective children

The proposition that impulsive children inhibit expressive behavior less than reflective children was investigated by providing third grade impulsive and reflective boys with either differential or nondifferential forms or successive discrimination training prior to tests for stimulus generalization. Consistent with specific predictions derived from Spence's theory on the roles of excitation and inhibition, it was found that: (a) Reflectives acquired the discrimination more rapidly, (b) reflectives achieved a higher level of discriminative performance, (c) impulsives exhibited more variable response reates during the nonreinforced stimulus, and (d) the type of training interacted with the child's conceptual tempo to determine the elevation and shape of the post-discrimination generalization gradients. The results provide support for the construct validity of the Matching Familiar Figures Test of reflectivity-impulsivity.     

The use of modeling to increase independent behavior

Three experiments were conducted aimed at increasing independence via use of modeling procedures in, respectively, two samples of neurotic outpatients and a sample of psychiatric inpatients. Significant gains in independence emerged in all three investigations. Subsidiary findings are reported regarding the operation in clinical contexts of ‘modeling-enhancers’ of demonstrated effectiveness in laboratory settings.     

Hemisphere dynamics in lexical access: automatic and controlled priming

Hemisphere differences in lexical processing may be due to asymmetry in the organization of lexical information, in procedures used to access the lexicon, or both. Six lateralized lexical decision experiments employed various types of priming to distinguish among these possibilities. In three controlled (high probability) priming experiments, prime words could be used as lexical access clues. Larger priming was obtained for orthographically similar stimuli (BEAK-BEAR) when presented to the left visual field (LVF). Controlled priming based on phonological relatedness (JUICE-MOOSE) was equally effective in either visual field (VF). Semantic similarity (INCH-YARD) produced larger priming for right visual field (RVF) stimuli. These results suggest that the hemispheres may utilize different information to achieve lexical access. Spread of activation through the lexicon was measured in complementary automatic (low probability) priming experiments. Priming was restricted to LVF stimuli for orthographically similar words, while priming for phonologically related stimuli was only obtained in the RVF. Automatic semantic priming was present bilaterally, but was larger in the LVF. These results imply hemisphere differences in lexical organization, with orthographic and semantic relationships available to the right hemisphere, and phonological and semantic relations available to the left hemisphere. Support was obtained for hemisphere asymmetries in both lexical organization and directed lexical processing.     

The influence of chance and contingency factors on the vocational choice process of nonprofessional workers

The present study investigated the perceived influence of chance and contingency factors on the career choices of nonprofessional workers. The sample was composed of 447 female workers and 470 male workers. As part of a larger study the workers listed the factors that had influenced their choice of their first job, their present job, and their most satisfying job. They were also asked to consider their entire work history and note events, people, or personal inclinations which influenced their vocational decisions. The workers then rated each of 27 chance or contingency factors concerning the extent of influence (great, some, none) on their career choices. The results are examined and discussed relative to the perceived importance of chance and contingency factors on the career choices of nonprofessional workers. The implications of the results for vocational theory and career counseling are considered.     

Quality of text recall as a function of children's classroom competence

This study demonstrated that the manner in which children, as students, chose to devise their recall was a function of the type of response register they maintained with their teachers. Students (mean C.A. = 10.4 years) who used an Imitative Response Register recalled significantly more referential propositions than students using either a Contingent or Noncontingent Response Register. In this sense, students employing an Imitative Response Register were more likely to reproduce text than the other Register Groups. Students (mean C.A. = 10.3 years) who used a Noncontingent Response Register recalled significantly more pragmatic inference propositions, i.e., either elaboration or distortion inference propositions, than students using either Imitative or Contingent Response Registers. In this sense, students employing a Noncontingent Response Register were more likely to embellish text than the other two groups. Finally, students (mean C.A. = 10.6 years) who used a Contingent Response Register recalled significantly more text-structured propositions, i.e., propositional and enabling inference propositions, than students using either Imitative or Noncontingent Response Registers. In this sense, students employing a Contingent Response Register were more likely to reconstruct text than the other two groups. These findings are discussed in terms of a classroom competence model of student behaviors.     

Attention and cognition

Forty 4-year-old children were subjects in an experimental designed to determine whether learning to attend to relevant cues is a sufficient condition for acquisition of length and number conservation. Three groups of non-conservers were trained by means of an oddity-problem procedure to attend to the cues specifying either length, number, or both length and number. They were subsequently tested along with an untrained control group on tasks of length, number, mass and continuous quantity conservation. Some improvement in conservation was found, but it was neither impressive in magnitude nor specific to the cues of training. For example, the group trained to attend to length cues conserved length about 25% of the time, the same rate at which this group also conserved number, mass, and liquid quantity. This non-specificity is contrary to an attention hypothesis and suggests instead that training, to the extent it was effective, induced a general, abstract quantitative knowledge.     

Neologistic jargon aphasia: A case report

This study examined aspects of speech produced by an aphasic subject with neologistic jargon. Grammatical category, syllabic structure, and phonemic characteristics of neologisms, paraphasias, and correct productions were analyzed and compared. Results tended to confirm an anomic component in this type of aphasia and to support a role for the postactivation of phonemic units from prior utterances in the phonemic composition of some neologistic productions. In opposition to prior claims, however, the results also showed a striking similarity between neologisms and paraphasias, suggesting that similar mechanisms may be involved in both types of aphasic error.     

Differential reinforcement of low rates performance by impulsive and reflective children

Third-grade boys classified as either cognitively impulsive or reflective were reinforced for key pressing according to a DRL (differential reinforcement of low rates) 6-sec schedule of reinforcement. Half of each group received instructions about the behavioral requirements for obtaining reinforcements. Prior to DRL training, impulsive Ss showed a low probability of key press responding at long interresponse time (IRT) intervals while reflective Ss exhibited an equal probability of terminating either short or long IRTs. During training and in the absence of instructions, impulsives exhibited a less precise temporal discrimination, characterized by a greater predominance of response bursts (0–2 sec IRTs) following reinforcements, than reflective Ss. While impulsive and reflective Ss displayed similar frequencies of collateral behavior between successively reinforced responses, impulsives engaged in the reinforced response more frequently and tended (p < .08) to obtain fewer reinforcements. Instructions served to enhance the DRL performance.
