A functional analysis of social reinforcement in vicarious verbal conditioning

This article reports the results of 629 subjects in three experiments designed to replicate and extend the phenomenon of vicarious verbal conditioning. Experiment I replicated the finding that subjects who responded most to vicarious verbal conditioning were aware of the contingency involved. Experiment II attempted to examine the effects of prior history with the verbal reinforcer on vicarious verbal conditioning by providing seven groups of subjects with varying classic conditioning histories prior to vicarious verbal conditioning. The null results associated with this experiment were hypothesized to be due to the fact that the vicarious verbal conditioning took place in a language laboratory where the subjects could hear but not see the model. Experiment III replicated Experiment II in a live group context as was done in Experiment I. The results showed a) that vicarious verbal conditioning was again found to take place, b) that associating the verbal reinforcer with a tone or tone plus money via forward classic conditioning potentiated the effects of the verbal reinforcer, c) that backward classic conditioning did not potentiate the reinforcer, d) nor did either of two sensitization procedures potentiate the effects of the verbal reinforcer. Both aware and unaware subjects evidenced vicarious verbal conditioning.     

Bizarreness effects in verbal tasks and subject-performed tasks

Abstract

Recognition and cued recall of ordinary action phrases (e.g. “open the book”) and bizarre ones (e.g. “plant the hammer”) were compared under two encoding conditions: in verbal tasks (VTs), subjects learned the phrases by simply listening to them; in subject-performed tasks (SPTs), subjects learned the phrases by performing the denoted actions (without real objects). Memory performance was better after SPTs than after VTs in recognition and cued recall. In addition to this already established finding, it was observed that recognition was better for bizarre phrases than for ordinary ones after VTs and that bizarreness was unrelated to recognition after SPTs. Cued recall, on the other hand, depended on bizarreness after VTs as well as after SPTs and, in contrast to the recognition findings, ordinary phrases were recalled better than bizarre phrases. This pattern of findings was explained by the assumptions that lexical and conceptual information is encoded after VTs and motor information is additionally encoded after SPTs, and that different kinds of information are used in recognition and cued recall, and after VTs and SPTs.     

Distributed practice in verbal recall tasks: A review and quantitative synthesis

The authors performed a meta-analysis of the distributed practice effect to illuminate the effects of temporal variables that have been neglected in previous reviews. This review found 839 assessments of distributed practice in 317 experiments located in 184 articles. Effects of spacing (consecutive massed presentations vs. spaced learning episodes) and lag (less spaced vs. more spaced learning episodes) were examined, as were expanding interstudy interval (ISI) effects. Analyses suggest that ISI and retention interval operate jointly to affect final-test retention; specifically, the ISI producing maximal retention increased as retention interval increased. Areas needing future research and theoretical implications are discussed.     

The effect of retrieval enactment on recall of subject-performed tasks and verbal tasks

The effect of retrieval enactment on memory for nouns (objects) or verbal phrases describing simple actions (e.g., “lift the box”) was addressed in two experiments. In Experiment 1, the type of object involved in the actions was manipulated, with three different types of object being used (body parts, laboratory-related objects, and external objects). In Experiment 2, the integration between the verb-noun pairs was manipulated (well-integrated vs. poorly integrated). Results from both experiments showed that whereas encoding enactment (motor encoding and verbal test) substantially improved the memory performance compared with a verbal condition (verbal encoding and verbal test), retrieval enactment (verbal encoding and motor test) had no major impact on the number of recalled nouns or phrases. Moreover, there was no additional effect of dual enactment (motor encoding and motor test). The overall pattern of the results suggests that there is a fundamental difference between motor processing at encoding and motor processing at retrieval, and the lack of encoding specificity advantage for the motor modality contradicts the view that encoding enactment of verbal commands results in storage of motor representations.     

Verbal fluency and verbal comprehension abilities in synonym tasks

Generating different synonym candidates and evaluating these candidates with respect to their synonymy with the stimulus word are two components of solving an open synonym task, which requires giving synonyms for a given word (cf. Janssen, Hoskens, & De Boeck, 1993). Separate subtasks were designed to identify these components. It is shown in this study that the generation component ability is primarily related to verbal fluency abilities, whereas the evaluation component ability is primarily related to verbal comprehension abilities. Moreover, evidence is given that these two component abilities can account for the correlations of the open synonym task with other ability measures.     

A functional perspective on group memberships: Differential need fulfillment in a group typology

The social motivation functions of intimacy, task, and social category groups were investigated. In two studies, participants were asked to consider the extent to which their group memberships fulfilled several needs. A factor analysis confirmed that the needs comprised three factors: affiliation, achievement, and identity. Intimacy groups were associated with affiliation needs, task groups were associated with achievement needs, and social category groups were associated with identity. A study using implicit measures reinforced those results, revealing the presence of the same implicit associations between group types and need fulfillments. A final study manipulated participants’ need state through a priming procedure. Priming a specific need (affiliation, achievement, and identity) led to an increased accessibility of the group type that was best suited to meet that need (intimacy, task, social category, respectively). Results help clarify the functional aspects of groups and have implications for the perception and organization of group-level information.     

False-belief understanding in 2.5-year-olds: evidence from two novel verbal spontaneous-response tasks

Recent research indicates that toddlers and infants succeed at various non-verbal spontaneous-response false-belief tasks; here we asked whether toddlers would also succeed at verbal spontaneous-response false-belief tasks that imposed significant linguistic demands. We tested 2.5-year-olds using two novel tasks: a preferential-looking task in which children listened to a false-belief story while looking at a picture book (with matching and non-matching pictures), and a violation-of-expectation task in which children watched an adult 'Subject' answer (correctly or incorrectly) a standard false-belief question. Positive results were obtained with both tasks, despite their linguistic demands. These results (1) support the distinction between spontaneous- and elicited-response tasks by showing that toddlers succeed at verbal false-belief tasks that do not require them to answer direct questions about agents' false beliefs, (2) reinforce claims of robust continuity in early false-belief understanding as assessed by spontaneous-response tasks, and (3) provide researchers with new experimental tasks for exploring early false-belief understanding in neurotypical and autistic populations.

Caregiver-patient dyads: Documenting the verbal instructions caregivers provide in joint cognitive tasks

Thirty spousal caregivers and their partners (who had been diagnosed as having primary degenerative dementia) jointly performed four cognitive tasks: Block Design (from the WAIS-R), the Token Test, and two memory tasks. Two of the tasks were unstructured, and two were structured. Caregivers served as the instructor on all tasks. Interactions were videotaped. Results showed that caregivers provided appropriate verbal instructions to a greater extent on the unstructured nonverbal task (Block Design) than on the unstructured memory task. Results are discussed in terms of implications for dyadic cognition research and intervention in dementia.     

A factor analysis of verbal abilities

A multiple-factor analysis was made of a battery of 42 tests of verbal abilities administered to 119 college adults. Where necessary, the distributions of test scores were normalized before the inter-test correlations were computed. Thurstone'sM (Memory or Rote Learning) factor has been confirmed, but hisV (Verbal Relations) factor seems to have been split into two or possibly three factors,C,J, andG; and hisW (Word Fluency) factor has been split into two factors,A andE. TheC factor seems to represent the richness of the individual's stock of linguistic responses, and theJ factor seems to involve the ability to handle semantic relationships. No satisfactory interpretation can as yet be made of theG factor. TheA factor seems to correspond to the speed of association for common words where there is a high degree of restriction as to appropriate responses. TheE factor is described as an associational facility with verbal material where the only restriction is that the responses must be syntactically coherent. The new factors are:F, facility and fluency in oral speech;H, facility in attaching appropriate names or symbols to stimuli; andD, speed of articulatory movements.This paper is a condensation of the writer's doctoral dissertation, A Factor Analysis of Verbal Abilities, on file at the library of the University of Minnesota.     

Psychometric and instructional validation approaches in the hierarchical sequencing of learning tasks

Two strategies used to test prerequisite relationships among intellectual skills were employed to examine the sequence of three types of subtraction tasks. A psychometric validation strategy yielded results similar to an instructional validation strategy. This finding provides support for the use of the more efficient psychometric approach for validating large numbers of learning hierarchies in relatively short periods of time.     

A behavioral systems approach to adaptive computerized instructional design

A computerized multimedia instructional system has been developed that adheres to behavioral systems principles for presenting both adaptive programmed instructional materials and laboratory simulations. This instructional software system, called MediaMatrix, is both an authoring environment and a presentation vehicle that adapts the complexity of presentations in real time to changes in a student’s current rate of progress. It incorporates an automated knowledge-generation system that tracks all interactions between the user and any instructional objects within the system. Such knowledge is used both for a research database and for an artificial-intelligence engine that constructs an estimate ofconcept association networks (Verplanck, 1992a). Such networks reflect a learner’s developing knowledge and skill base, and may be used for tutorial advising during student use.     

A system for the assessment of human performance in concurrent verbal and manual control tasks

A multipurpose laboratory system incorporating a voice interactive terminal and graphic display system is described. The facility is designed to investigate some aspects of human performance on concurrent verbal and tracking tasks. The results of a pilot study showing decrements in dual-task performance are reported.     

Visuospatial over verbal demands in predicting Tower of London planning tasks

The role of verbal and visuospatial information processing in Tower of London (TOL) tasks was investigated. The first part of the investigation examined the verbal and visuospatial abilities and preferred cognitive style (visualizer vs. verbalizer) of 79 participants, in an inter-individual differences approach. Visuospatial abilities significantly predicted TOL performance, but the impact of cognitive style was negligible. The second part applied a dual-task manipulation of concurrent interference of TOL planning tasks on verbal and visuospatial memory, using the same participants. Concurrent processing of the TOL tasks diminished visuospatial memory performance considerably but had no effect on verbal memory, and there was no interaction between cognitive style and memory. These findings clearly underscore the role of visuospatial information processing in TOL tasks and indicate little bearing of verbal or visual cognitive style on TOL problem solving. These results have important implications for TOL and cognitive style in clinical application and cognitive neuroimaging research.     

Easier tasks can have better discriminating power: the case of verbal fluency

Loren and Jean Chapman highlighted the importance that the psychometric characteristics of a task may have when comparing different populations (L. J. Chapman & J. P. Chapman, 1973, 1978). Specifically, they pointed out that when comparing 2 tasks measuring different constructs, there is a greater likelihood of finding larger deficits on a task with higher discriminating power, irrespective of what the task measures. While researchers have addressed this issue, they typically have assumed that more difficult tasks have greater discriminating power, often without actually measuring discriminating power. In this article, the authors present data from 2 studies using phonologic and category fluency tasks to demonstrate that the critical factor for task selection and matching is discriminating power, not task difficulty.     

Visual field differences in verbal tasks: Effects of task familiarity and sex of subject

Four experiments using normal subjects investigated differences in magnitude of the right visual field (RVF) superiority as a function of word material (frequency and concreteness/imageability status), nonword letter strings (some of which were homophonic with nonpresented real words), and type of task (overt naming or lexical decision with discriminatory manual responses) as well as sex of the subject and the subject's familiarity with the material. Both latency and error measures showed that RVF superiority was more consistent when overt naming was required and with male subjects. For female subjects engaged in lexical decisions, a left visual field (LVF) superiority was often apparent, especially in the first half of an experimental sequence; when actually naming the items aloud, they showed field asymmetries similar to males. Except from an analysis of errors, there was little evidence to support differential right hemisphere mediation of high frequency concrete/imageable materials. It is suggested that in females, right hemisphere space normally reserved for visuospatial processing may have been invaded by secondary speech mechanisms. These mechanisms appear to operate at an essentially lexical level and may act in a supportive or auxiliary capacity for difficult or unfamiliar material; they seem to be equally concerned with both phonological and graphological processing and may account for the well-known female superiority in verbal tasks and inferiority in visuospatial tasks. Other findings are discussed such as the degree of consistency of the field differences, both for the same subjects and for the same stimulus materials under different task requirements and experimental conditions.     

Evaluation of an indirect assessment for identifying tasks for functional analysis

Although a demand analysis is helpful for identifying potential establishing operations for the functional analysis (FA) demand condition, it may not always be practical due to time constraints. A potential alternative is the Negative Reinforcement Rating Scale (NRRS), an indirect assessment tool that may serve as a time efficient alternative to a demand analysis. The experimenter assessed the reliability and validity of the NRRS for 5 individuals with autism spectrum disorder who exhibited problem behavior. Multiple types of interrater reliability were assessed across 2 informants, and NRRS outcomes were compared to a subsequent demand analysis and FA to assess its validity. Reliability was high (M = 84%) for NRRS numerical ratings of categories but low (M = 32.9%) for specific examples provided. NRRS-identified highly aversive tasks yielded better correspondence with demand analysis outcomes than did NRRS-identified less aversive tasks.     

Re-examining the effects of verbal instructional type on early stage motor learning

The present study investigated the differential effects of analogy and explicit instructions on early stage motor learning and movement in a modified high jump task. Participants were randomly assigned to one of three experimental conditions: analogy, explicit light (reduced informational load), or traditional explicit (large informational load). During the two-day learning phase, participants learned a novel high jump technique based on the ‘scissors’ style using the instructions for their respective conditions. For the single-day testing phase, participants completed both a retention test and task-relevant pressure test, the latter of which featured a rising high-jump-bar pressure manipulation. Although analogy learners demonstrated slightly more efficient technique and reported fewer technical rules on average, the differences between the conditions were not statistically significant. There were, however, significant differences in joint variability with respect to instructional type, as variability was lowest for the analogy condition during both the learning and testing phases, and as a function of block, as joint variability decreased for all conditions during the learning phase. Findings suggest that reducing the informational volume of explicit instructions may mitigate the deleterious effects on performance previously associated with explicit learning in the literature.     

A verbal behavior analysis of auditory hallucinations

A review of recent research on the non-medical control of auditory hallucinations is presented. It is suggested that the decreases in hallucinatory behavior obtained in studies using aversive contingencies may be attributable to the disruption of the chains of behavior involved. The results of several additional studies are interpreted as indicating that methods of stimulus control and the use of incompatible behaviors may be effective in reducing the rate of auditory hallucinations. Research relating auditory hallucinations to subvocalizations is presented in support of the view that hallucinatory phenomena are sometimes related to the subject's own vocal productions. Skinner's views (1934, 1936, 1953, 1957, 1980) are then presented as possible explanations of some hallucinatory behavior. It is suggested that some auditory hallucinations consit of the mishearing of environmental and physiological stimuli as voices in a fashion similar to that which Skinner observed in his work with the verbal summator. The maintenance of long chains of such responses may be largely attributable to self-intraverbal influences (such as are present during automatic writing). With some auditory hallucinations, this progression involves first mishearing ambiguous stimuli as voices and then attributing the voices to some cause (e.g., insanity, the television, radio, or God). Later, the frequent and ongoing chains of such behavior may contaminate other verbal responses. Such verbal behavior may be parasitic on "normal verbal behavior" (and hence, not directly dependent on consquences for maintenance), may be cued by various stimuli (including respiration), and may interfere with other covert and overt behavior. Several studies to investigate this view are presented. It is hoped that such research will lead to a better understanding of the major issues involved in the etiology and treatment of auditory hallucinations in particular and perhaps of psychosis in general.     

Maladaptive functional relations in client verbal behavior

Skinner's analysis of verbal behavior is applied in this paper to several kinds of maladaptive behavior with which clinicians must deal. Lying, denial, and poor observing skills are discussed as defective tacting repertoires. Demanding and manipulative behaviors are mands that obtain immediate reinforcement at the expense of disrupting long-term interpersonal relations. Obsessing is runaway intraverbal behavior. Variables that enter into the maladaptive functional relations are examined.
