The selective impact of question form and input mode on the symbolic distance effect in children

Five experiments are reported on the symbolic distance effect (SDE) and related phenomena with 6- and 9-year-old children. In the first of these, children were asked to judge the relative sizes of animals in verbal and pictorial tests featuring the comparatives "bigger" and "smaller." A perceptual condition with actual objects was included by way of comparison. A Symbolic Distance Effect was obtained for both lexical and pictorial input. Mode differences were also observed. Pictures produced faster responses than words, and congruity effects occurred only in the pictorial condition. Although performance was similar in tests with either comparative, our subsequent experiments on both 6- and 9-year-olds reveal a significant asymmetry in the child's capacity to verify statements of relation as a function of the direction along the (size) continuum implied by the question. However, important differences between age groups also apparent in the data lead us to conclude that the older subjects develop strategies to overcome this asymmetry by translating certain statements of relation into a form more congruent with their natural modes of encoding.     

Men and women's acceptance of coercive sexual strategies varied by initiator gender and couple intimacy

Seventy-two men and 86 women read vignettes describing five coercive strategies for obtaining sexual intercourse on a date. Subjects rated the acceptability of strategies used by male and female initiators for couples who were or were not sexually intimate. Subjects generally rejected all tactics. Results revealed a continuum of increasing rejection from verbal pressure and sexual stimulation, followed by mock force, followed by intoxication and physical force. Although women were more rejecting of any strategy than were men, women were slightly less opposed to verbal pressure and stimulation for “more sex” rather than for “first-time sex.” Women equally rejected most male- and female-initiated strategies, but men were more accepting of female-initiated strategies. Results are explained in terms of sex role norms prescribing that men be initiators and women be gatekeepers in sexual interaction.     

Sex as a Status Variable in Work Settings: Female and Male Reports of Dominance Behavior

This study shows that sex is an important status variable in occupational settings. The basic hypothesis that males, because of a status prerogative, would be more likely than females to use nonverbal and verbal dominance behaviors, including intimate gestures, toward their opposite sex co-workers was confirmed. Subjects (88 female and 69 male samples from two institutions of higher learning) reported dominance behaviors (a) toward opposite sex co-workers; (b) from opposite sex co-workers; (c) toward opposite sex superiors; and (d) from opposite sex superiors. Analysis of the sexual dominance items revealed that sexual intimacy is expressable along the same continuum as traditional dominance gestures. The hypothesis that sex competes with other status variables was supported. If the sexual dominance patterns explored in this study prove widespread, institutions may wish to provide programs aimed at raising employee awareness of these interactions.     

Training Verbal-Nonverbal Correspondence

This study assessed the influence of strengthening a verbal self-referent statement on later corresponding nonverbal behavior performed outside the treatment setting. Seventeen preschool children were randomly assigned to two groups: (1) Experimental group, in which subjects were reinforced for repeating anti-litter statements; (2) control group in which subjects merely repeated statements unrelated to littering. Subsequent paper-picking behavior in the lavatory was counted. The results suggest that verbal, training can strongly augment the control function of self-repeated instructions in preschool children despite a time lapse between training and opportunity to perform the behavior, and a difference between the training and the performance settings.     

The effect of order of presentation of verbal probability expressions on numerical estimates in a medical context

Many medical decisions are made on a probability estimate. Models of risk benefit calculations in health behaviour rarely articulate how people perceive and appraise such probability. Cognitive processes may mediate the processing of probability expressions and may be important to understand the meaning or the range of meanings that probability statements portray to patients. Past studies have indicated that verbal expressions of probability are vague and subject to individual interpretation. On the theoretical level when subjects are asked to translate a set of verbal probability expressions, ranging from high to low, into their equivalent numerical expressions subjects usually produce a continuum of numerical equivalents also ranging from high to low. In practice clinicians frequently communicate information about uncertainty to the patients by verbal probability estimates. This study explored the effect of the order of presentation of the verbal expressions on the numerical probabilities produced by a group of medical students (n?=?87) in relation to medical probabilities. The results showed that the order of presentation (descending vs. random) of the verbal probability expressions was found to have a significant effect on three of the seven numerical probabilities produced by the subjects. The order effect is discussed to together with implications for clinical practice.     

Structural behavioural analysis as a basis for discriminating between genuine and simulated rape allegations

This paper explores the potential utility of structural behavioural analysis as a basis for discriminating between genuine and simulated accounts of rape. Structural analysis examines the coherence of the combination of behaviours in the account based against the co‐occurrence of behaviours in genuine accounts. Three analyses compared 142 genuine rape with 30 simulated statements in terms of the base rates of behaviours reported within the statements, and in terms of the behavioural coherence of each statement to an established behavioural structure. Results suggest that genuine statements tend to report a larger total number of behaviours than simulated statements; that pseudo‐intimate behaviours are significantly more often reported in genuine statements while some violent behaviours are more frequently reported in simulated statements; and that simulated statements are less behaviourally coherent than genuine statements. We concede the many limitations of the study but argue that results provide tentative evidence that false claimants, not fully appreciating the phenomenological experience of rape, overemphasise the significance of violent and demeaning behaviour whilst underplaying the significance of pseudo‐intimate behaviour.

Probing sensory and associative semantics for animals and objects in normal subjects

Abstract

Neuropsychological studies of patients with “category-specific” semantic memory disorders have fuelled a debate concerning the organisation of knowledge. In particular it has been suggested that the reported double dissociation between knowledge of animals and living things on the one hand, and objects on the other, reflects a more fundamental division of semantic representation into functional-associative and sensory-visual domains. The present study attempted to investigate whether there were systematic differences along these dimensions in normal subjects using a sentence-verification technique. It was found that response times were significantly longer for verification of statements concerning the sensory attributes of objects than for statements about their associative attributes. In the case of animals, there were no differences in response latency to associative or sensory statements. In the light of this previously unreported fractionation within verbal semantics, the possible consequences for models of semantic memory are discussed.     

Intimacy in response to direct gaze

Believing that they were participating in a study of encounter groups, male and female subjects were encouraged to deliver a personally revealing monologue to a same-sex listener whose visual behavior had been “programmed” by the experimenter. In the four experimental conditions, designed to explore the role of gaze as a stimulus, as a potential reinforcer, and as a source of feedback, the listener provided (a) continuous direct gaze; (b) direct gaze contingent upon intimate statements; (c) continuous gaze aversion; or (d) gaze aversion contingent upon intimate statements. The intimacy of the speaker's monologue was rated by a “blind” observer, the listener, and the speaker himself. Direct gaze, whether constant or contingent, appeared to promote intimacy between females and reticence between males, while gaze avoidance had the opposite effects. The only raters who disagreed with this assessment were the male speakers, who felt that they had been most intimate in the two direct gaze conditions. Positive feelings including liking for the listener and task satisfaction also were associated both with self-revelation and with direct gaze among females but not among males.     

Valence and Arousal Ratings for Velten Mood Induction Statements

Participants rated 84 statements adapted from Velten's original mood induction statements—designed to induce positive and negative mood—on two dimensions of emotion (valence and arousal), using the Self Assessment Manikin (SAM) (P. J. Lang, M. M. Bradley, & B. N. Cuthbert, 1999). Fifty-two of these Velten positive, negative, and neutral statements yielded SAM valence ratings that were consistent with Velten's previous valence designation (E. Velten, 1968). Reliability analyses for the positive, negative, and neutral statements indicated a high level of internal consistency in the three statement groups. Arousal and valence ratings of the statements were positively correlated. Related issues concerning differences in rating verbal versus visual emotional stimuli and recommendations for future work to improve the validity of Velten's mood induction statements are addressed.     

Incorporating quantitative information into a linear ordering

Ss were required to learn linear orderings of four terms (A > B > C > D). Each pair of terms was described as being either "just barely," "moderately," or "very much" different on some meaningful dimension. Two distinct strategies for coding this information were observed. Some Ss varied the spacing of the terms along some continuum (e.g., A_B___C_____D), while others spaced the terms evenly along a continuum and inserted verbal tags to represent the quantitative information (e.g., A just barely B moderately C very much D). The former strategy was consistently found to be superior. Performance did not vary as a function of the quantitative difference between the terms.     

Jung's Psychological Types: Meaning and Consistency of the Questionnaire

Third-grade children (n = 72) completed arithmetic problems in an individually conducted experimental session while receiving one of three types of verbal feedback (positive statements, negative statements, or their combination), either randomly or contingent on the accuracy of their answers. Random feedback produced a higher rate of responding than did contingent feedback with no loss of accuracy. The varying types of verbal feedback statements did not produce differential effects on either rate or accuracy measures. These results were discussed in terms of the ineffectiveness of verbal feedback in producing differential results with tasks not involving new learning and in terms of mechanisms which could account for the efficacy of random feedback.     

Cues-pause-point language training: Structuring trainer statements to provide students with correct answers to questions

This study assessed the applicability of Cues-Pause-Point language training procedures in teaching students to obtain information from the statements of others. Two mentally retarded subjects, one of whom was echolalic, received training on one set of stimuli but not on another. During training the subjects were encouraged to remain quiet before, during, and briefly after the presentation of statements and then verbalize (i.e., answer a question) using the verbal cue(s) that had been presented in the statement. Correct responding reached 100% to the trained stimuli and both subjects' responding improved to the untrained stimuli. Posttests revealed that subjects used the trainer's statements to answer novel questions. The results suggest that Cues-Pause-Point procedures may be useful in teaching severely retarded individuals the functional use of observing and listening to others' verbal behavior.     

Effect of context on perception of emotion among psychiatric patients

The purpose of this research was to examine the extent to which verbal statements of context influence psychiatric patients' perception of photographs of emotion (fear, anger, sadness, and happiness). The major findings showed that, when photographs were paired congruently with context statements, there were significant changes in agreement among subjects on two of the four emotion stimuli. There was significantly less agreement on the meaning of facial expressions when the stimuli for fear, anger, and happiness were accompanied by incongruent verbal statements than when they were viewed alone. These data appear to have implications for practitioners working with this population.     

Increasing mentally retarded adolescents' verbalizations about current events

The effects of antecedent and consequent events on the verbal behavior of three institutionalized mentally retarded adolescents were examined. Verbal statements, related to current national and international events, were recorded after exposures to television news programs. The study examined the accuracy of verbalizations as a function of: (1) exposures to television news presentations in massed (i.e., viewing the entire news program before an opportunity to describe it) versus distributed from (i.e., viewing each news item separately with each followed by an opportunity to describe it), and (2) contingent tokens and social praise for correct verbal responses (i.e., statements corresponding to news items presented). Both the temporal distribution of news presentations and the reinforcement procedures improved the accuracy of verbal statements emitted by the subjects.     

Duration and numerical estimation in right brain‐damaged patients with and without neglect: Lack of support for a mental time line

Previous studies have shown that left neglect patients are impaired when they have to orient their attention leftward relative to a standard in numerical comparison tasks. This finding has been accounted for by the idea that numerical magnitudes are represented along a spatial continuum oriented from left to right with small magnitudes on the left and large magnitudes on the right. Similarly, it has been proposed that duration could be represented along a mental time line that shares the properties of the number continuum. By comparing directly duration and numerosity processing, this study investigates whether or not the performance of neglect patients supports the hypothesis of a mental time line. Twenty‐two right brain‐damaged patients (11 with and 11 without left neglect), as well as 11 age‐matched healthy controls, had to judge whether a single dot presented visually lasted shorter or longer than 500 ms and whether a sequence of flashed dots was smaller or larger than 5. Digit spans were also assessed to measure verbal working memory capacities. In duration comparison, no spatial‐duration bias was found in neglect patients. Moreover, a significant correlation between verbal working memory and duration performance was observed in right brain‐damaged patients, irrespective of the presence or absence of neglect. In numerical comparison, only neglect patients showed an enhanced distance effect for numerical magnitude smaller than the standard. These results do not support the hypothesis of the existence of a mental continuum oriented from left to right for duration. We discuss an alternative account to explain the duration impairment observed in right brain‐damaged patients.     

Children's prepared and unprepared lies: can adults see through their strategies?

We investigated adults' ability to detect children's prepared and unprepared lies and truths. Furthermore, we examined children's strategies when lying. Thirty children (11–13 years) were interviewed about one self‐experienced and one invented event each. Half had prepared their statements, the other half not. Sixty adult observers assessed the veracity of 10 videotaped statements each. Overall deception detection accuracy (51.5%) was not better than chance. The adults showed higher accuracy for unprepared statements (56.6%), than prepared statements (46.1%). The adults reported to have used more verbal than nonverbal cues to deception, especially the Detail criterion. The most frequent verbal strategy reported by the children was to use real‐life components (e.g. own or others' experiences); the most frequent nonverbal strategy was to stay calm. Arguably, the low accuracy is due to adults' failure to see through the lying children's strategies. Copyright © 2006 John Wiley & Sons, Ltd.     

Reducing emotional reasoning: An experimental manipulation in individuals with fear of spiders

We investigated the effects of smiling on perceptions of positive, neutral and negative verbal statements. Participants viewed computer-generated movies of female characters who made angry, disgusted, happy or neutral statements and then showed either one of two temporal forms of smile (slow vs. fast onset) or a neutral expression. Smiles significantly increased the perceived positivity of the message by making negative statements appear less negative and neutral statements appear more positive. However, these smiles led the character to be seen as less genuine than when she showed a neutral expression. Disgust + smile messages led to higher judged happiness than did anger + smile messages, suggesting that smiles were seen as reflecting humour when combined with disgust statements, but as masking negative affect when combined with anger statements. These findings provide insights into the ways that smiles moderate the impact of verbal statements.     

GENERALIZATION OF VERBAL CONDITIONING TO VERBAL AND NONVERBAL BEHAVIOR: GROUP THERAPY WITH CHRONIC PSYCHIATRIC PATIENTS1

Twelve chronic hospitalized female patients received token reinforcement contingent on two separate classes of verbalizations: (a) positive statements about optional activities available in the hospital setting, and (b) positive statements about people. Cross-class generalization of reinforced verbal responses about activities to overt behavior was tested by actual participation in activities; within-class generalization of verbal responses about people to verbalizations in another stimulus setting was assessed in a structured interview situation. A multiple baseline design with contingency reversals was employed to demonstrate experimental control of both classes of verbalizations in the group sessions. Positive statements about activities generalized to actual participation in activities, while generalization of positive statements about people to verbalization in the extra-group setting did not occur.     

Effects of emotional illness and age upon the resolution of discrepant messages

To determine their ability to interpret messages, normal and disturbed children, adolescents, and adults (ns = 10) were shown videotaped statements containing discrepant verbal and nonverbal components and statements containing consistent verbal and nonverbal components. No significant differences were observed between subjects in response to the consistent messages regardless of age or mental status; however, pronounced differences occurred under the condition with discrepant messages. Among normal subjects a developmental shift was observed, i.e., an inverse relation was found between age and reliance upon verbal content. Younger normal subjects relied upon the verbal content of a message in interpretation, while adults relied upon the nonverbal elements. Disturbed subjects regardless of age relied primarily upon the verbal content of the discrepant message.
