Effects of Disaggregation on Managerial Assessment Center Validity

Assessment center validity data from a large, international petrochemical company were disaggregated by managerial level and business stream. As with previous research, the correlations were higher for the current job grade criterion than for performance ratings. Overall, disaggregating the data did not have the effect of increasing the assessment center—performance rating validities. However, when the validation data were disaggregated by business stream, there were differences in the pattern of the relationships between assessment factors and performance.     

ANALYZING ALERTNESS AMONG PEOPLE WITH PROFOUND MULTIPLE DISABILITIES: IMPLICATIONS FOR PROVISION OF TRAINING

We investigated whether variations in alertness among individuals with profound multiple disabilities affected subsequent responsiveness to training programs. Three experiments were conducted involving 5 people. In Experiment 1, results indicated that alertness of 3 individuals increased with provision of skill-acquisition training programs. Results also indicated no predictive relationship between alertness levels prior to training and subsequent responsiveness to training. Experiment 2 replicated results of Experiment 1 with 2 participants from Experiment 1 and an additional participant. Results of Experiment 2 also indicated that the increased alertness levels accompanying provision of training were not a function of the participants simply being in an inactive environment prior to training. Results of Experiment 3 indicated that alertness of an additional participant increased through provision of another training intervention, involving a systematic preference assessment. Responses during the preference assessment appeared to be unrelated to previously existing alertness levels. These findings suggest the need for caution when considering the withholding of scheduled training because an individual appears to be nonalert.     

EFFECTS OF A VOICE OUTPUT COMMUNICATION AID ON INTERACTIONS BETWEEN SUPPORT PERSONNEL AND AN INDIVIDUAL WITH MULTIPLE DISABILITIES

We evaluated a means of increasing staff members' interactions with an individual with multiple disabilities through use of a voice output communication aid (VOCA). When activated, the VOCA allowed the individual to communicate through synthesized speech. Results indicated that staff members interacted with the individual more frequently when she had access to the VOCA, suggesting that VOCAs may represent an alternative to more traditional staff management programs for increasing interactions.     

Assessment of HIV counselling and social care services in a London hospital

The use of, and satisfaction with, counselling and social care services was investigated among HIV-infected clients attending HIV specialist climes at Guy's Hospital and Southwark Social Services, London. A survey of 71 clients with HIV infection was carried out using a self-administered questionnaire. The greatest demand was for advice about income support, housing, counselling for the HIV test, counselling for depression or anxiety, psychological support for coping with HIV, help with sleeping problems, mobility allowance, and help with furniture/household appliances. Overall, 57% thought the service was good or excellent; 66% of respondents thought they would use the services in the future. Over nine in ten clients had used the psychosocial support services at some stage since their HIV diagnosis, although only two-thirds anticipated that they would have need of these services in the future. The psychosocial support service will need to remain responsive to the shift in demand for this service, as well as the changing needs of clients who use it.     

THE PRICE OF EXPERTISE:

Abstract— When shown a idled container, people often fail to appreciate that the surface of the liquid contained within should remain horizontal with respect to the ground. This study investigated how amenable this bias is to experience in relevant everyday situations. Surprisingly, liquid surfaces that waitresses and bartenders considered natural deviated even more from horizontal than was the case for comparison groups. This finding is, to our knowledge, the only documented case in which performance declines with experience. We suggest that practical experience promotes a functionally relative perspective, in which the orientation of the liquid's surface is evaluated relative to that of its container as opposed to being related directly to the surrounding environment. The container-relative perspective, in turn, evokes a perceptual bias that is responsible for the systematic errors observed on this task.     

Perceiving geographical slant

People judged the inclination of hills viewed either out-of-doors or in a computer-simulated virtual environment. Angle judgments were obtained by having people (1) provide verbal estimates, (2) adjust a representation of the hill’s cross-section, and (3) adjust a tilt board with their unseen hand. Geographical slant was greatly overestimated according to the first two measures, but not the third. Apparent slant judgments conformed to ratio scales, thereby enhancing sensitivity to the small inclines that must actually be traversed in everyday experience. It is proposed that the perceived exaggeration of geographical slant preserves the relationship between distal inclination and people’s behavioral potential. Hills are harder to traverse as people become tired; hence, apparent slant increased with fatigue. Visually guided actions must be accommodated to the actual distal properties of the environment; consequently, the tilt board adjustments did not reflect apparent slant overestimations, nor were they influenced by fatigue. Consistent with the fact that steep hills are more difficult to descend than to ascend, these hills appeared steeper when viewed from the top.     

Congruence reconsidered

Carl Rogers' definitions of congruence are discussed. Four specific requirements are identified for the concept and practice of therapeutic congruence. Drawing on examples from practice, the interface between congruence and the other necessary and sufficient conditions of change is examined.     

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. S. A.     

Human sensitivity to temporal proximity: The role of spatial and temporal speed gradients

Estimates of temporal proximity (sometimes called time-to-collision) from random-dot flow patterns are shown to be based upon retinal speed, rather than upon changes in dot density. Neither the spatial nor the temporal gradient of motion is essential to the task, but estimates can be made from either alone. Performance is unaffected by the addition of rotational motion, suggesting that observers axe capable of extracting the radial component of motion, which contains all the relevant information, from complex stimuli.     

Validation of the Children's Assertive Behavior Scale

Relationships between sociometric indices and scores of 160 elementary-school children on the Children's Assertive Behavior Scale (CABS) were examined to determine whether this instrument differentiates children of varying levels of social competence. Children who obtained either high or low scores on peer nominations of friendship and admiration were identified and compared on CABS passive, aggressive, and assertive scores. Children who scored high on positive peer nominations responded in a significantly less aggressive manner than children who received low scores on such nominations. These effects were observed for the CABS format that consisted of stimulus situations involving adults but not for the form involving peers. With regard to responses toward peers, a significant interaction between sex and sociometric status emerged. These findings suggest the importance of incorporating subject variables such as race and sex as well as assessments of behavior toward both adults and children in isolating and training components of social skill.The authors wish to express their appreciation to Jean Birbilis, Gail Hammersly, Marieta Knopf, and Donna Wadley for their assistance in data collection and analysis.
