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.     

The influence of verbal specifications on ratings of relative properties of pictures

Summary Sixty subjects were shown pictures each containing two objects (A and B). The objects were unobtrusive with respect to relative properties such as long — short, big — small, etc. The pictures were preceded by sentences referring either to objects A and B or only to object A. Object A was dimensionally specified: The same object was called, e.g., long for one and short for a different subject. Ratings during a later test (without presentation of the pictures) revealed that not only were objects A remembered according to the verbal specification provided during the presentation but ratings of objects B also changed in line with the specification of A. This was true even when object B had not been mentioned verbally during the presentation. In this way, verbal specifications had an effect beyond the referential bond. It is concluded that models based on the assumption that the semantic interpretation of an event depends on the application of syntactic rules — rules indicating, e.g., to which object an adjective refers — lack an important clue.     

The role of verbal ability in the processing of complex verbal information

Summary This study investigated the relation between psychometric mental-ability test scores and several reaction-time measures; a simple-reaction task, a choice-reaction task, the Posner and Mitchell (1967) letter-identification task, and a variation of the sentence-verification task. Scores on the Raven Advanced Progressive Matrices and the Verbal Subtest of the Scholastic Aptitude Test (SATV) were obtained. The less complex information-processing tasks replicate earlier studies in which general intelligence was only marginally related to reaction-time measures. The sentence-verification task systematically varied task complexity. Several direct and derived measures from the task were significantly correlated with psychometric mentalability measures. However, even though a number of precautions were taken to ensure that the sentence-verification task assessed purely verbal-processing efficiency, there was little evidence for an important task-specific relation between verification measures and verbal ability. Moreover, despite its relative verbal complexity, sentence verification did not reflect a greater relationship to verbal ability than other tasks did. Overall, the information-processing efficiency measures used in this study suggested a fairly general, rather than a task-specific, relationship to intellectual ability.The research presented in this paper was conducted while the first author was affiliated with the University of Georgia, U.

The effects of facial adiposity on attractiveness and perceived leadership ability

Facial attractiveness has a positive influence on electoral success both in experimental paradigms and in the real world. One parameter that influences facial attractiveness and social judgements is facial adiposity (a facial correlate to body mass index, BMI). Overweight people have high facial adiposity and are perceived to be less attractive and lower in leadership ability. Here, we used an interactive design in order to assess whether the most attractive level of facial adiposity is also perceived as most leader-like. We found that participants reduced facial adiposity more to maximize attractiveness than to maximize perceived leadership ability. These results indicate that facial appearance impacts leadership judgements beyond the effects of attractiveness. We suggest that the disparity between optimal facial adiposity in attractiveness and leadership judgements stems from social trends that have produced thin ideals for attractiveness, while leadership judgements are associated with perception of physical dominance.     

The quantity and quality of marital interaction related to marital satisfaction: A behavioral analysis

An assessment instrument is presented for the evaluation of the quantity and quality of dyadic interaction, as well as for the daily recording of behaviors presented and omitted which influence marital satisfaction. Comparison of data from ten happy couples and from ten couples entering therapy indicated two distinct dysfunctional patterns among distressed couples, with significantly different patterns of time-together and positive/negative ratios differentiating the happy versus therapy groups. Independent behavioral recording for 14 consecutive days significantly increased husband-wife agreement on a traditional adjustment questionnaire without significantly increasing or decreasing the level of satisfaction being assessed. There was no difference between groups as to interspousal agreement on amount of time together. However, the happy couples agreed on daily quality ratings of the 72 15-minute segments significantly more often than did the distressed couples. Couples at the extremes of the happy-distressed continuum reported rewarding and punishing, respectively, in response to the partners presence, regardless of behaviors emitted. Midrange happy couples defined "pleasant" as positive behaviors presented; midrange distressed couples defined "pleasant" as negative behaviors omitted. Theoretical and clinical implications of behavioral analysis of sequential patterns are discussed.     

The relationship of specific mental ability measures compared to a general mental ability measure to quality and quantity performance on a clerical job sample

Barrett (1993) presented evidence that mental ability measures designed specifically for the prediction of performance in tasks and jobs have validity at least equal to that of tests of general mental ability, while having advantages such as lower adverse impact. The current study demonstrates that the match in specificity of predictor and criterion can be attained through simple changes in the scoring of standard mental and clerical ability tests. A sample of 51 university students completed a battery of pre-employment tests and, a week or two later, worked on a clerical job sample. The results indicated that quality of performance (number of errors on the task) was best predicted using the number of errors made on the predictor tests while quantity of work was only predicted by the number correct. A test of general mental ability did not correlate with either criterion. These results contradicted the conclusions of Schmidt (1993) that specific ability tests have no incremental validity above a general ability test.Ralph Alexander died before this report was complete. Consequently, the conclusions are those of the first two authors.     

Two faces of verbal ability

Although psychologists often think and act as though there were only one global domain of verbal ability, there are actually two—verbal comprehension and verbal fluency. For reasons that are not entirely clear, verbal comprehension has received, by far, the most attention in both the psychometric and information-processing literatures. Both are important, pervasive abilities. For example, whereas reading draws primarily on verbal comprehension ability, writing draws primarily on verbal fluency ability; similarly, whereas listening primarily requires verbal comprehension, speaking depends more heavily on verbal fluency. This article seeks to redress some of the imbalance in the literature on the study of these two broad domains of verbal ability. The article is divided into four main parts. The first parts set the stage by placing the study of verbal abilities in a historical context within the field of psychology. The second part describes some alternative approaches to the study of verbal comprehension, summarizing what we have learned from these approaches. The third part reviews some of the few studies that have examined verbal fluency and then describes our own new information-processing approach to the study of this ability. The fourth part explores the relations between the two faces of verbal ability—comprehension and fluency.     

Instructor's transformational leadership: university student attitudes and ratings

We extend leadership research by examining the effect of an instructor's transformational leadership on university students. 120 undergraduate students provided ratings for their instructors on Charisma, Intellectual Stimulation, and Individual Consideration as well as the Instructors' Performance and the Students' Involvement in class. Multiple regression analyses indicated that Intellectual Stimulation and Charisma together accounted for 66.3% of the variance in the prediction of Instructor's Performance ratings. In turn, Intellectual Stimulation and Individual Consideration combined to account for 55.1% of the variance in predicting Student Involvement.     

Children and aging: attitudes, differentiation ability, and quantity and quality of contact

The attitudes and age differentiation ability of forty-seven 3- to 5-year-old children toward pictures of older and younger people were assessed. In addition, cognitive performance on a seriation task as well as the quantity and quality of each child's contact with adults over 60 years of age were measured. Chi squares were performed by sex and age of stimulus photograph on the attitudinal questions. One of the chi squares reached significance on the age comparison and two on the sex comparison. In addition, sign tests were used to assess the direction of the trends on the questions, and both age and sex trends were significant at the .05 level with children being more likely to choose pictures of younger rather than older models and female rather than male models. Ability to correctly order pictures by age was significantly related (r = .53, p less than .001) to the seriation ordering task. Four of the 18 correlations between contact and attitudinal variables were significant and negative.     

The effect of verbal context on olfactory perception

Three experiments were conducted to examine how verbal context and sensory stimulation interact to influence odor hedonic perception. Eight common odors were presented in their natural and synthetic forms, and verbal labels designating name and source (natural, synthetic) information were either explicitly given, self-generated, falsely provided, or not provided. Results revealed that verbal information about source influenced hedonic ratings whether or not the odorant itself was also present. When odorants were presented without verbal labels, olfactory evaluations were based in sensation. Name and source information contributed different levels of meaning and influence to perceptual evaluations. The findings are discussed with reference to an experiential-collocation model for odor-label interactions and a dual-coding hypothesis for olfactory perception.     

Virtual team leadership: The effects of leadership style and communication medium on team interaction styles and outcomes

This study investigated the effects of transformational and transactional leadership styles and communication media on team interaction styles and outcomes. Teams communicated through one of the following three ways: (a) face-to-face, (b) desktop videoconference, or (c) text-based chat. Results indicated that transformational and transactional leadership styles did not affect team interaction styles or outcomes; that the mean constructive interaction score was higher in FTF than videoconference and chat teams, but not significantly higher in videoconference than chat teams; and that teams working in richer communication media did not achieve higher task performance than those communicating through less rich media. Finally, mean team cohesion scores were higher in FTF and videoconference than chat teams, but not significantly higher in FTF than videoconference teams. These results provide further evidence that communication media do have important effects on team interaction styles and cohesion.     

The effect of verbal reinforcement on career choice realism

Twenty-four male undergraduates viewed 102 slides containing occupational titles and stated whether or not each represented a realistic career choice. Each subject was given three trials, with the experimental subjects receiving positive verbal reinforcement on the second trial for realistic responses. (If the choice was congruous with the individual's occupational type, as determined by the Vocational Preference Inventory, it was scored as realistic.) The results of the research revealed a tendency for all subjects to increase in career choice realism as a function of participation in the experiment, with significantly (p < .05) more experimental subjects than control subjects demonstrating an operant pattern of responses. Implications of the findings for counselors were discussed.     

The relationship between athletic participation and high school students' leadership ability

This study examined the relationship between adolescents' participation in athletics and their leadership skills. In a sample of 60 suburban high school students, athletes demonstrated significantly greater leadership ability than did nonathletes (according to their mean scores on the Leadership Ability Evaluation). Female athletes showed greater leadership ability than did male athletes, although the difference between their scores was not statistically significant. The implications of these findings for school athletic programs are discussed.     

The effect of dimension content on observation and ratings of job performance

Recent theory and research in the performance appraisal area (e.g., Denisi, Cafferty, & Meglino, 1984; Feldman, 1986; Ilgen & Feldman, 1983; Williams, Denisi, & Blencoe, 1985) have suggested that providing information regarding the performance dimension to be rated will cause raters to select appropriate observational schemata and, as a result, produce higher quality ratings. A study was conducted to determine if giving raters dimension-relevant information prior to performance observation would affect their attention processes and rating quality. Prior to watching a videotape of an instructor giving a lecture, 156 subjects were given either: 1) correct information, 2) incorrect information, or 3) no information regarding dimensions of performance they would subsequently be asked to rate. The results indicated that giving prior information regarding dimension content affected subjects' attention processes. Further, raters receiving no information and those receiving misinformation prior to performance observation produced less accurate ratings compared to expert raters. Ratings produced by subjects receiving correct information did not differ significantly from experts' ratings. These results are discussed in terms of both their practical and theoretical implications.
