When “reliability” fails,must a measure be discarded?—The case of Kinesthetic Aftereffect

Critics of Kinesthetic Aftereffect (KAE) recommend abandoning it as a personality measure largely because of poor test-retest reliability. Although no test can be valid if lacking true reliability, to discard a measure because of poor retest reliability is an oversimplification of validation procedures. This pitfall is exemplified here by a reexamination of KAE. KAE scores involve measures before (pretest) and after (test) aftereffect induction. Internal analysis of a KAE study showed: Differential bias is present; its locus is the second session pretest; its form makes second-session pretest scores functionally more similar to first- and second-session test scores and functionally more dissimilar to first-session pretest scores. Given this second session bias, the retest correlation tells us nothing about the true reliability of a one-session KAE score. However, if a measure possesses external validity, it must to some degree show true reliability. Based upon a literature review of one-session KAE validity studies, we conclude that one-session KAE scores are valid and hence show true reliability. KAE remains a promising personality measure.     

An investigation of the interaural time difference threshold for speech

The interaural time difference threshold for speech has been reported to be approximately 35 μsec (Cherry & Sayers, 1956), a value substantially larger than the 6 ~sec reported for broadband noise signals by other experimenters (e.g., Tobias & Zerlin, 1959). In the two studies just mentioned, however, different subjects and psychoacoustical methods were employed; thus, it is unclear whether larger interaural time differences are needed to lateralize speech signals. The purpose of this experiment, therefore, was to compare lateralization performance for speech and nonspeech stimuli. Interaural time difference thresholds were obtained for speech, speech spectrum noise, speech multiplied noise, and 200-, 500-, and 1,000-Hz sinusoids for the same subjects using a 2 IFC experimental paradigm. Under these conditions, speech and speech-multiplied noise yielded essentially the same interaural time difference thresholds.     

The use of photographs as occupational stimuli

The purpose of this study was to examine the potential of photographic stimuli portraying well-known occupational activities in order to elicit vocationally relevant responses. Color photographs of persons performing occupational tasks or activities were the stimuli used to determine if aspects of the photographs would elicit discriminating responses. Eighty special education high school students were asked individually to respond to 15 color photographs. Out of a maximum of 1200 possible picture identifications, 35 responses were scored incorrect or unknown as to content. These results indicated 97.1% effectiveness in identifying the stimulus content by this population. Therefore, photographs consisting of occupational content can discriminate as stimuli by eliciting content-appropriate responses. Implications for further research and application of this finding are discussed.     

Inertial acceleration as a measure of linear vection: An alternative to magnitude estimation

The present study focused on the development of a procedure to assess perceived self-motion induced by visual surround motion—vection. Using an apparatus that permitted independent control of visual and inertial stimuli, prone observers were translated along their headx-axis (fore/aft). The observers’ task was to report the direction of self-motion during passive forward and backward translations of their bodies coupled with exposure to various visual surround conditions. The proportion of “forward” responses was used to calculate each observer’s point of subjective equality (PSE) for each surround condition. The results showed that the moving visual stimulus produced a significant shift in the PSE when data from the moving surround condition were compared with the stationary surround and no-vision condition. Further, the results indicated that vection increased monotonically with surround velocities between 4 and 40°/sec. It was concluded that linear vection can be measured in terms of changes in the amplitude of whole-body inertial acceleration required to elicit equivalent numbers of “forward” and “backward” self-motion reports.     

Working Together: Perceived Self- and Collective-Efficacy at the Workplace1

Collective efficacy is the extension of Bandura's (1977) self-efficacy concept to groups (Bandura, 1982, 1986). Self-efficacy refers to judgments that people make about their personal or individual competency. Collective efficacy concerns judgments that people make about a group's level of competency. This paper contributes to the theory and measurement of collective efficacy and to an understanding of its relationship to self-efficacy and performance. Elementary school teachers' collective- and self-efficacy were measured. The academic domain is well suited to the study of collective-efficacy because the organizational units (schools) all perform the same function (education). The findings supported the hypothesis that, in at least some domains, self-efficacy and collective-efficacy are related but independent constructs. As hypothesized, it was also found that the socioeconomic composition of a school's student body, was a strong predictor of teachers' collective-efficacy. Although teachers' collective-efficacy was associated with school level achievement, this relationship was no longer significant when prior achievement levels were controlled. It was suggested that future research should examine individual behaviors, attitudes, and beliefs that might serve as mediators between efficacy and performance. It was also suggested that the relationship between collective efficacy and organizational culture should be explored.     

Pastoral consultation through a community Mental Health Center

Conclusion Pastoral consultation through a mental health center in Kansas has been a beneficial experience for participating clergymen and the mental health center staff. This consultation has provided interested clergymen an opportunity to learn effective ways of serving parishioners through the church. The clergymen and mental health center staff have also begun to realize the mental health implications of religious resources, as well as ways in which ministers and the mental health center staff can effectively work together in serving troubled individuals within the local community. Pastoral consultation may become a means through which other community mental health centers and local clergymen can form meaningful professional relationships. The continuance of a pastoral consultation program over a longer period of time is needed to determine its possibilities and liabilities for assistingA report of one aspect of a special study project on Community Clergy and Mental Health, made possible by a grant from W. Clement Stone to the Menninger Foundation.

The Validity of Unstructured Panel Interviews: More than Meets the Eye?

When considered at the aggregate level, a weak level of validity was found for unstructured panel interviews in the prediction of the job performance and training success of corrections officers. Aggregate analyses also revealed that panel judgments made a small incremental contribution to the prediction of job performance relative to paper credentials and that the two sources of information were only weakly related. However, considerable variation in simple and incremental validity was found at the level of individual panel members and among subgroups of panels. The findings suggest that aggregate analyses underestimate the validity of the typical unstructured panel interview.     

From Passive to Proactive Motivation: The Importance of Flexible Role Orientations and Role Breadth Self-efficacy

Despite the widely held belief that a proactive workforce is necessary for competitive advantage, research investigating how to assess and promote such change is limited. Two potentially important precursors to proactivity include flexible role orientation (FRO) and role breadth self-efficacy (RBSE). These concepts have been shown to have construct validity and to be distinct from related dispositional variables, but their discriminant validity in terms of outcome variables has not been demonstrated. In this article, I show that FRO and RBSE are factorially distinct from outcomes commonly used in organisational research (job satisfaction, organisational commitment, and job strain). I also show that, as expected, the proactive motivation and traditional outcome variables have different relationships with various predictor variables. I outline the study implications, and suggest a broader research agenda on proactive motivation.
