Visual and verbal modes of information processing and cognitively-based coping strategies: An extension and replication

This study was designed to investigate the interaction between the use of an imaginallybased vs a verbally-based coping strategy with subjects who were selected on the basis of strong preferences for either visual or verbal modes of information processing. Forty-eight female students were subjected to a cold-pressor task. Measures of pain tolerance, pain threshold and a pain rating were obtained. The findings indicated that there was not a significant relationship between preferred cognitive style and the types of coping strategy provided. However, the treatments combined were found to be significantly more effective than the no-treatment condition on all three dependent measures. A structured debriefing revealed that use of visual vs verbal coping strategies did not differ as a function of treatment type or preferred cognitive style. It was concluded that individuals may demonstrate considerable flexibility in adapting to different types of cognitively-based coping strategies.     

An eye fixation analysis of multialternative choice

Eye fixations were recorded while subjects chose their most preferred of six used cars. Fixation sequences of the form X-Y-X-... were used to identify pair comparisons. This assumption was validated by verbal protocols and by a comparison between X-Y-X and X-Y-X-Y-... patterns. The results of three experiments showed: (1) that the multialternative choice process was composed primarily of pair comparisons; (2) that evaluative processing took placeonly during these comparisons; (3) that strategies for selecting the pairs were based primarily on information processing convenience; (4) that the sequence of pair comparisons was not used by the subjects as a sequential elimination process; and (5)that subjects changed their strategies to adapt to different task environments. These results have implications for current choice models and for the use of eye fixations in other complex tasks.     

Methodological issues in judgment and decision-making research: Concurrent verbal protocol validity and simultaneous traces of process

This paper examines two dimensions of concurrent verbal protocol validity. First, whether verbalization affects process and outcome (reactivity) was examined by comparing concurrent verbal protocol traces with those from a computer search process tracing method, the latter being a complete trace of information acquisition from experimental materials. Earlier findings that verbalization affects time were confirmed. However, verbalization did not affect amount and pattern of acquisition or accuracy of judgments. Second, whether concurrent verbal protocols are complete was examined by comparing concurrent verbal protocol and computer traces that were simultaneously obtained in a treatment in which subjects verbalized as they acquired information from the computer. The verbal traces less completely captured information acquisition behavior than computer search. This suggests that, although concurrent verbal protocols provide greater insight into decision behavior than computer search, the latter is a more reliable information-acquisition trace. Thus, if information acquisition is of primary interest and if computer search activities can be naturally integrated into performing the primary task, computer search is preferred to concurrent verbal protocols. However, if information use or retrieval from long-term memory is of primary interest, concurrent verbal protocols are preferred to computer search. Finally, this paper examined whether the simultaneous use of concurrent verbal protocols and computer search provides traces of information acquisition and use that are as complete as when each method is independently applied. Although computer search tended to limit subjects verbalizations of evaluative operators, this effect may be eliminated by practice on the computer prior to collecting data.     

Insight without awareness: On the interaction of verbalization, instruction and practice in a simulated process control task

Four experiments in which subjects learned to control two versions of a complex simulated process control task show that verbalizable knowledge of procedures used to perform these tasks is very limited and is acquired late in learning. Individual learning curves associated with these tasks showed sudden improvements in performance, which were not accompanied by a similar increase in verbalizable knowledge. It was also found that verbal instructions consisting of exemplar memorization, strategies for rule induction, simple heuristics, and experts' instructions were all effective in enhancing novice subjects' performance. A theoretical framework is proposed in which subjects draw on two separate but interacting knowledge structures to perform these tasks. One knowledge structure is based on memory for past experiences (close analogies), and the other is based on one's current mental model of the task. Implicit sets of competing rules that control response selection are derived from both sources of knowledge. It is suggested that dissociations between task performance and verbalizing occur because memory-based processing tends to have more control over response selection because of its greater specificity, whereas a mental model tends to be the preferred mode for verbal reporting because of its greater accessibility.     

Rarely Occurring Headaches and Rarely Occurring Blindness: Is Rarely=Rarely? The Meaning of Verbal Frequentistic Labels in Specific Medical Contexts

In three experimental studies, factors were examined which might influence the interpretation of verbal frequentistic labels in a specific context (i.e. side effects of medical drugs). In Study 1, we directly assessed subjects' numerical equivalents of three verbal labels (recommended for use by the German Federal Health Agency), which were embedded in stylized leaflets for medical drugs; we compared the estimates with those obtained in a context-free situation. The major findings were that (1) subjects' numerical equivalents for the verbal labels were clearly lower in the context condition than in the context-free situation, (2) subjects'; interpretations appeared to depend on the seriousness of the side effects, but (3) this dependency disappeared when explicit base rates were provided. In Studies 2 and 3, we indirectly examined the influence of the seriousness of the side effects, their frequency, and of the mode of expression (verbally versus numerically) by asking for risk judgments for and choices between drugs. Results of particular importance were that (1) seriousness and frequency of side effects had the same influence on judgments and choices but the mode of expression had no significant effect on either judgments or choices; (2) when subjects’ individual numerical equivalents of verbal labels were used in the leaflets, numerically described drugs were judged equally risky as verbally described drugs but were significantly preferred for consumption. These findings have theoretical relevance for research on the processing of verbal and numerical frequentistic expressions as well as a number of practical implications for the communication of medical information.     

Additive and interactive effects in memory for subject-performed tasks

Abstract

Three experiments were carried out to explore reasons for the superior recall and recognition of subject-performed tasks (SPTs) relative to memory for the equivalent verbal commands. In Experiment 1, list structure was varied; list structure affected recall, but the variable did not interact with the SPT/command manipulation. The same absence of an interaction was found in Experiment 2 with respect to different retrieval conditions and also with respect to the age of adult subjects. Experiment 3 confirmed that the age difference was as large for SPTs as it was for verbal commands. In addition, an interaction between SPT/command and levels of processing was found in Experiment 3. Differences between the additive and interactive patterns of results are discussed in terms of SITS contributing both additional (possibly motoric) information and also conceptual information that overlaps with information added by other variables.     

Patterns of Preference for Numerical and Verbal Probabilities

We report results of an experiment designed to test a principle formulated by Budescu and Wallsten (1995), that, when communicating uncertainty information, mode choices are sensitive to sources and degrees of vagueness. In addition, we examined subjects’ efficacy in using such uncertainty information as a function of communication mode, source, and vagueness. In phase one of the experiment, subjects in a dyad used precise (numerical) or imprecise (verbal) expressions to communicate to a remote partner precise or vague uncertainty about the likelihoods of events. Spinner outcomes were used to generate precise uncertainty while answers to almanac questions were used to elicit vague uncertainty. In phase two, subjects saw the events paired with their partners’ estimates of similar events, and were asked to gamble on one event from each pair. Communication mode preferences were measured as the relative frequency that subjects chose the numerical mode to either express or receive uncertainty information regarding the events. Efficacy was measured as the relative frequency that subjects choose from the pair the event associated with the objectively more probable uncertainty expression. Underlying uncertainty interacted with direction of communication to affect preferences for modes of expression of the probabilities. Subjects preferred precise (numerical) information, especially for precise events (spinners). For vague events (questions), their preference for precise (numerical) information was stronger when receiving than when communicating information. Similar preferences were reflected in the efficiency of subsequent gamble decisions based on the probability estimates. Specifically, decisions were more efficacious (i.e. consistent with Expected Utility) when degrees of precision in events and estimates matched. © 1997 by John Wiley & Sons, Ltd.     

INCREASING VERBAL INTERACTION AMONG ELDERLY SOCIALLY ISOLATED MENTALLY RETARDED ADULTS: A GROUP LANGUAGE TRAINING PROCEDURE

The present study examined the effectiveness of a group language training procedure for directly increasing and generalizing the rate of verbal interaction among four elderly, socially isolated, moderately mentally retarded men. A withdrawal of treatment design was used to examine the effect of the procedure that used verbal prompts, behavioral rehearsal, and contingent social praise. Changes in behavior were examined in two generalization settings, one similiar to the training environment (Generalization I) and the other arranged as part of the subjects' daily routine (Generalization II). Baseline data indicated no verbal interaction among the subjects. During treatment the training procedure increased the rate of subjects' verbal interactions not only in the training situation, but also in the two generalization settings. An analysis of the data obtained during the Generalization II situation indicated that subjects' verbal interaction increased not only among themselves, but with nonsubject peers present in this setting. Follow-up data showed that increases in rates of verbal interaction were maintained four months after the cessation of training. The implications of the results for program generalization and work with the language deficient individual is discussed.     

Simultaneity in Processing of Verbal and Spatial Information

Recent studies involving recall of verbal and spatial information produced conflicting results. In some cases investigators found males recalled verbal and spatial information equally well whereas females did less well on spatial than verbal information, but in other cases no sex differences were found. They also differed in that one study found processing of verbal and spatial information to be independent whereas others suggested trade-offs might occur. Using college-age subjects (17-25 yrs) with equal numbers of males and females (total n = 186) two experiments were performed to examine these differences. Although overall differences were found favoring verbal recall, females’ recall of spatial information was relatively poorer than males. Using a procedure designed to avoid possible artifactual depression of combined performance, we concluded that processing of spatial and verbal information is simultaneous in nature.

     

Effects of movie violence on aggression in a field setting as a function of group dominance and cohesion.

In this quasi-experimental field study, delinquent members belonging to two cottages viewed aggressive commercial movies every evening for a week, while at the same time, subjects from two other cottages were exposed to neutral commercial movies. Behavioral observations were obtained through a nonhier-archical, minimally inferential procedure of a time-sampling nature; they were taken during a baseline week (at noon and in the evening), a treatment week (noon and evening) and a posttreatment week (noon). The main immediate effects of the violent films were an overall increase of both active behaviors and physical aggression; the effects on verbal aggression were more persistent but limited to one of the two cottages. On the other hand, more interactions occurred as an immediate consequence of viewing the films in both neutral treatment cottages; moreover, one of these two cottages also decreased its level of physical (short-term effect) and verbal (short- and long-term effects) aggression. In the aggressive treatment cottage, which was most affected, subjects who were most dominant, most popular, and least popular were influenced the most: an opposite effect was exhibited by those subjects who were judged as least aggressive by their peers. Complementary data are presented and discussed; the difference between the single individual laboratory paradigm and the existing group field paradigm is especially stressed.     

Verbal working memory and sentence comprehension

This target article discusses the verbal working memory system used in sentence comprehension. We review the concept of working memory as a short-duration system in which small amounts of information are simultaneously stored and manipulated in the service of accomplishing a task. We summarize the argument that syntactic processing in sentence comprehension requires such a storage and computational system. We then ask whether the working memory system used in syntactic processing is the same as that used in verbally mediated tasks that involve conscious controlled processing. Evidence is brought to bear from various sources: the relationship between individual differences in working memory and individual differences in the efficiency of syntactic processing; the effect of concurrent verbal memory load on syntactic processing; and syntactic processing in patients with poor short-term memory, patients with poor working memory, and patients with aphasia. Experimental results from these normal subjects and patients with various brain lesions converge on the conclusion that there is a specialization in the verbal working memory system for assigning the syntactic structure of a sentence and using that structure in determining sentence meaning that is separate from the working memory system underlying the use of sentence meaning to accomplish other functions. We present a theory of the divisions of the verbal working memory system and suggestions regarding its neural basis.     

Teaching Interpersonal Skills with Videotape

Three methods of teaching interpersonal skills to chronically ill psychiatric clients were compared. It was hypothesized that: (1) there would be no difference in interpersonal skills gain between subjects who planned and produced a videotape about interpersonal skills (group 1) and similar subjects who attended classes to learn interpersonal skills and viewed the videotape produced by group 1 (group 2); and that (2) there would be no difference in interpersonal skill gain between these two groups and similar subjects who attended classes to learn interpersonal skills but do not view the videotape (group 3). Interpersonal skill gain was measured by both subject self-assessment and rater assessment of interaction and task performance behaviors. Group 1 showed the most improvement on the posttest self-assessment scores and made some interpersonal skill gain demonstrated by subjective observations. However, the sample size was too small to detect a significant difference between any of the three treatment groups. Implications for using videotape to teach interpersonal skills are discussed.     

The effect of instruction with relational and item-specific elaborative strategies on young children's organization and free recall

One hundred and sixty second-grade children were assigned on the basis of a free recall pretest to four instruction conditions and were given a series of lists of pictures for free recall. For three groups, the instructions were directed at encoding either (a) list organizational information, (b) item-specific semantic information, or (c) organizational and individual item information, while the fourth group constituted a “No-training” control with standard free recall instructions. The subjects received either related or unrelated lists during the training phase and related or unrelated lists during two post-tests, immediately following and 1 week after training. For both types of lists, instructions emphasizing list organization were more effective than those emphasizing item-specific elaboration. Subjects given individual item elaborative instructions showed levels of recall which were comparable to those of the control subjects. While the combined effect of organizational and individual item processing did not exceed the performance produced by organizational instructions alone, the degree of generalization was greater for subjects processing both kinds of information, especially when subjects received related lists during training.     

Physical/verbal aggression: Sex differences in style1

Two studies exploring the use of physical/verbal aggression are reported, the first using women and the second using men as subjects. Both studies allowed subjects to choose between and control the intensity of two response modes: verbal aggression (insults) and physical aggression (electric shock). Aggressive style was investigated over two levels of arousal, sex of experimenter, and sex of provocateur-victim. Results indicated that women aggressed discriminatively in the verbal mode as a function of their arousal, while men were capable of aggressing discriminatively in both the verbal and physical modes. Men who had been disagreed with and punished by a female victim-provocateur in the presence of a male experimenter or by a male victim in the presence of a female experimenter demonstrated high levels of physical aggression compared to the other groups.     

The effect of response choice relatedness on pantomime and verbal recognition ability in aphasic patients

Twenty aphasic and twenty control subjects were examined on two versions of a pantomime recognition and a verbal recognition test; one version containing response choices conceptually/semantically related to target responses, the other containing unrelated response choices. The aphasic group was inferior to controls on the pantomime and verbal recognition tests, although the magnitude and consistency of the differences between aphasics and controls were greater for the pantomime test. The presence of conceptually/semantically related response choices on the pantomime recognition test significantly reduced test scores of aphasic patients, and this reduction was related to the magnitude of the effect of response choice relatedness on their verbal recognition test performance. The findings are consistent with an interpretation of aphasia as an impairment of a central symbolic ability which can affect processing for meaning in both verbal and nonverbal modes of communication.     

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.     

The effects of value confrontation and reinforcement counseling on the career planning attitudes and behavior of adolescent males

An experiment was conducted to compare the relative effectiveness of a value confrontation procedure and a procedure based on verbal operant conditioning in enhancing career development attitudes and increasing the frequency of information-seeking behavior in rural adolescent males. Ninety subjects were identified as internally controlled or externally controlled based on their locus of control scores and then randomly assigned to one of the two experimental treatment groups or a control group. The value confrontation procedure involved developing an awareness of self-dissatisfaction about one's career planning and relating this self-dissatisfaction to the importance one gave to the values logical and responsible. These values had been identified empirically in this study as having a relationship to career planning. The reinforcement counseling treatment involved the interpretation of individual career maturity data followed by the verbal operant conditioning of responses indicative of career maturity. Post tests administered 7 weeks after the treatments showed that the value confrontation procedure resulted in significantly greater frequency of information seeking for internally controlled subjects when compared to the reinforcement counseling and control procedures. No treatment was significant in increasing the maturity level of career development attitudes.     

Verbal interactions of aggressively and nonaggressively predisposed males in a drinking situation

The effects of progressive intoxication were studied in male social drinkers classified from prior histories as either aggressively (A) or nonaggressively (NA) predisposed while intoxicated. Two groups of two A and two NA subjects engaged in videotaped group discussions that were analyzed by Bales interaction process analysis (IPA). At comparable levels of ad libitum alcohol intake in a natural drinking environment, significantly more verbal activity was displayed by the A subjects than by the NA subjects (P <.001), including IPA category D (P <.025). The A subjects tended to address the group as a whole rather than individual members (P <.001) and NA subjects rather than other A subjects (P <.01). Free testosterone levels assessed from saliva were higher among A subjects than among NA subjects (P <.05) with no significant changes related to time and progressive intoxication. The results suggest that the tendency to behave aggressively while intoxicated may be a fairly stable individual trait, possibly related to androgen levels and active or coercive modes of social communication.     

The meaning of observed violence: Real vs. fictional violence and consequent effects on aggression and emotional arousal

Sixty male subjects were either attacked or treated neutrally by a confederate, after which each saw a videotape of two men fighting. Subjects were informed that fight was either real or fictitious or were given no explanation of it. Subjects who had previously been attacked and had observed the fight under a set to perceive it as real were subsequently more punitive in their treatment of the confederate than subjects in all other conditions. The combination of prior attack and observation of real violence also sustained blood pressure (BP) at near the level produced by the attack, whereas BP of attacked subjects in the other conditions declined during the time the fight was observed. Palmar sweat measures revealed that observation of real violence was more arousing than observation of fictitious fighting. The results are discussed in terms of the effects that the reality of observed violence has on emotional arousal.     

Successive vs simultaneous processing of superimposed visual stimuli

A visual analogue of Savin’s (1967) auditory task was used to examine preferred order of recall and order of recall accuracy for two pairs of visually superimposed digits. Savin (1967) and Rollins, Everson, and Schurman (1972) found that Ss preferred to recall simultaneous auditory information in successive order, even though the information was presented over a single channel. In the present experiments, Ss were found to prefer strongly to recall visual information in simultaneous order. On the other hand, the results of Rollins et al (1972), that Ss are equally accurate when forced to recall simultaneous auditory information in either the preferred or nonpreferred mode, were replicated for this visual task. The results of these experiments, together with the experiment reported by Rollins et al (1972), indicate that verbal information is processed differently by these two sensory systems.
