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.

Effects of Helper and Recipient Sex on the Experience and Outcomes of Comforting Messages: An Experimental Investigation

The purpose of this experimental study was to examine whether and in what ways the sex of the helper and the recipient moderate the effects of comforting messages in face-to-face interactions. A total of 216 participants disclosed an emotionally upsetting event to a confederate trained to display different levels of nonverbal immediacy and verbal person centeredness. Men and women responded very similarly to comforting messages that exhibited different levels of verbal person centeredness and nonverbal immediacy, and this response similarity was not moderated by the sex of the helper. Both men and women were most comforted by messages that exhibited high levels of person centeredness and nonverbal immediacy, and they were least comforted by messages that exhibited low levels of these qualities. Moreover, both sexes viewed highly person-centered and immediate messages as exhibiting the highest comforting quality, and, with one minor exception, both sexes viewed helpers who used these messages as the most competent.     

Cerebral Organization of Motor Programming and Verbal Processing as a Function of Degree of Hand Preference and Familial Sinistrality

Seventy-six right- and left-handed subjects responded to monaurally presented verbal stimuli (CVs) using their right and left hands on separate occasions. Both degree of hand preference and familial sinistrality (FS) were taken into account. It was found that, contrary to expectation, the manual response interfered with the verbal perception task, but only in the consistent strong handers. The pattern of interference suggests that those with a consistent hand preference (right or left) have general motor programming in the left hemisphere. Those with an inconsistent strong hand preference probably have some degree of general motor programming in both hemispheres. No effect for FS was found for the lateralization of verbal processing or general motor programming.     

B. F. Skinner: The Writer and His Definition of Verbal Behavior

Skinner's definition of verbal behavior, with its brief and refined versions, has recently become a point of controversy among behavior analysts. Some of the arguments presented in this controversy might be based on a misreading of Skinner's (1957a) writings. An examination of Skinner's correspondence with editors of scientific journals shows his sophisticated mastery of English and his knowledge of contemporary approaches of linguistics, and might help to settle the meaning of the passages involved in the controversy. A more precise definition of verbal behavior, deduced from Skinner's distinction between verbal and nonverbal operants, is suggested, and a possible reason why Skinner did not define verbal behavior in the terms proposed by this alternative definition is discussed. The alternative definition is more compatible with a functional approach to behavior and highlights what is specific to verbal behavior by pointing to the conventions of the verbal community. Some possible consequences of adopting this alternative definition are described.     

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.     

Enhanced Conversational Recall and Reduced Conversational Interference as a Function of Cognitive Complexity

This study examines the relationship between cognitive complexity and conversational recall. Three hypotheses are put forward arguing that individuals high in cognitive complexity will (a) recall more person-oriented conversational information, (b) recall more person-oriented information in an interference condition, and (c) recall more total information from a conversation than subjects low in cognitive complexity. Subjects were 72 college students who observed a video taped conversation. Recall was elicited by means of a free recall task and an 18-item multiple choice test. MANOVA and canonical discriminant-analysis results support each hypotheses.     

Psychosocial Variables Associated With Verbal Abuse as a Form of Intimate Partner Violence Against Women in a Spanish Sample

This article aims to analyze psychosocial variables associated with verbal abuse in women who suffer intimate partner violence. The following factors, taken from the scientific literature, were examined: social and family isolation; low self-esteem; an excess of empathy for the abuser; submission; psychological dependence on the abuser; and, self-blame as internal attribution for the cause of abuse. Our results show that low self-esteem has a direct relationship with verbal abuse. Additionally, family (including in-laws) and social (from friends, workmates, and neighbors), isolation are significantly and positively related to verbal abuse. The results of our study raise questions about the adoption of gender roles and their consequences when stereotyped tendencies are acquired. Implications, as well as ideas future research, are discussed.     

Risk-Taking and Risk-Avoiding Behavior: The Impact of Some Dispositional and Situational Variables

The purpose of this research was to assess the ability of a decision making model to correctly predict subjects' preferences for one of two alternatives; one alternative was highly valued but risky, whereas the other was less valuable but more certain. The model was based on the assumption that an additive relationship exists among self-efficacy, self-worth, and parental expectations in influencing subjects' propensity to take risks. The results suggested that the model did not work as expected. Rather, self-efficacy emerged as the principle variable influencing the risk-taking and risk-avoiding decision-making behaviors of subjects when a variety of resources were involved.     

Failing to Recall: Examining the Effects of Trace Decay and Interference on Memory for Campaign Information

Voters are continuously bombarded with information during political campaigns, yet a consistent conclusion from research on voter learning is that individuals remember far less information about political candidates than one might expect. What remains unclear is why memory for campaign information is so poor. The present study examines two explanations for memory failure. Using an experimental design, the present study explores whether campaign information fades from memory (trace decay) or whether extraneous information impedes an individual's subsequent ability to recall campaign information (interference). The results suggest that examining the ways in which the larger information environment influences recall of campaign information has important implications for the importance we attribute to campaign information in models of voter decision making.     

The differential effect of background music on memory for verbal and visuospatial information

Background music is a part of our everyday activities. Considerable evidence suggests that listening to music while performing cognitive tasks may negatively influence performance. However, other studies have shown that it can benefit memory when the music played during the encoding of information is also provided during the retrieval of that information, in the so-called context dependent memory effect. Since controversial results may be attributed to the nature of the material to be memorized, the aim of the present study is to compare the potential effect of consistent background music on the immediate and long-term recall of verbal and visuospatial information. Experiment 1 showed that instrumental background music does not benefit nor decrease recall of a list of unrelated words, both at the immediate and the 48-hours-delayed tests. By contrast, Experiment 2 revealed that the same background music can impair immediate and therefore long-term memory for visuospatial information. Results are interpreted in terms of competition for neurocognitive resources, with tasks mostly relying on the same brain hemisphere competing for a limited set of resources. Hence, background music might impair visuospatial memory to a greater extent than verbal memory, in the context of limited capacity cognitive system. In conclusion, the nature of the material to be learnt must be considered to fully understand the effect of background music on memory.     

Recall of Television Commercials as a Function of Viewing Context: The Impact of Program-Commercial Congruity on Commercial Messages

The effect of the congruity between the involvement types of advertising commercial and a television program on the effectiveness of the commercial was studied. Participants (N = 103) viewed either a cognitive or an affective commercial for a product, which was embedded in either a cognitive or an affective television program. The results showed that the effects of the congruence influence the impact on memory. Free recall and cued recall were significantly influenced by the program-commercial congruity. Free recall and cued recall were significantly higher for the cognitively involving commercial in the cognitively involving program context than in the affectively involving program context. Similarly, free recall and cued recall were significantly higher for the affectively involving commercial in the affectively involving program context than in the cognitively involving program context.

Some Implications of a Behavioral Analysis of Verbal Behavior for Logic and Mathematics

The evident power and utility of the formal models of logic and mathematics pose a puzzle: Although such models are instances of verbal behavior, they are also essentialistic. But behavioral terms, and indeed all products of selection contingencies, are intrinsically variable and in this respect appear to be incommensurate with essentialism. A distinctive feature of verbal contingencies resolves this puzzle: The control of behavior by the nonverbal environment is often mediated by the verbal behavior of others, and behavior under control of verbal stimuli is blind to the intrinsic variability of the stimulating environment. Thus, words and sentences serve as filters of variability and thereby facilitate essentialistic model building and the formal structures of logic, mathematics, and science. Autoclitic frames, verbal chains interrupted by interchangeable variable terms, are ubiquitous in verbal behavior. Variable terms can be substituted in such frames almost without limit, a feature fundamental to formal models. Consequently, our fluency with autoclitic frames fosters generalization to formal models, which in turn permit deduction and other kinds of logical and mathematical inference.     

The Influence of Learning Style and Cognitive Ability on Recall of Names and Faces in an Older Population

The present study examined whether, for older adults, a verbal or imagery cognitive style is associated with recall of names and faces learned in an experimental condition. Cognitive abilities that are represented in current models of face recognition and name recall were also examined. Those abilities included picture naming, verbal fluency (i.e., naming items within a given category), vocabulary comprehension, visual memory, and the learning of unassociated word pairs. Fifty older adults attempted to learn first and last names of 20 student actors and actresses pictured on videotapes (40 names total). On average, participants learned the most first names, followed by last names, and the fewest full names. The greater the number of responses on a questionnaire associated with an imagery cognitive style, the more the names of faces were correctly identified by participants. There was no significant relationship between a verbal cognitive style and the number of names and faces recalled. As for cognitive abilities, all of the abilities measured—with the exception of vocabulary comprehension—were significantly associated with the number of names and faces learned. A regression analysis indicated that the best predictor of successful name-face learning was the participants' ability to learn and recall 5 unrelated word pairs. When that cognitive measure was deleted from the regression analysis, delayed visual memory and verbal fluency were the next best predictors of the older adults' ability to learn names and faces.     

Variation in Coordination of a Discrete Multiarticular Action as a Function of Skill Level

The authors investigated coordination modes that emerged as a function of the interaction between skill level and task constraints in a multiarticular kicking action. Five skilled, 5 intermediate, and 5 novice participants attempted to satisfy specific height and accuracy constraints in kicking a ball over a barrier. Skilled and intermediate groups demonstrated a functional coordination mode involving less joint involvement at the proximal joints and greater joint involvement at distal joints, mimicking a chip-like action in soccer. Conversely, the novice group tended to produce larger ranges of motion throughout the kicking limb in a driving-like kicking action. Key differences were also found for task outcome scores, joint angle-angle relations, and ball-trajectory plots between the skilled and intermediate groups and the novice group. Findings from this study demonstrated that joint involvement during this discrete multiarticular action is a function of skill level and task constraints rather than a consequence of a global freezing-freeing strategy suggested in some previous research. The authors also highlight the merit of using a model of the acquisition of coordination in examining how coordination modes for multiarticular actions differ as a function of skill.
