The effect of probing on deceivers and truthtellers

This study examined the effect of probing for additional information on the accuracy of deception detection. One hundred forty-eight experimental interactions were analyzed to see whether deceivers and truthtellers behave differently when probed and whether probing improved deception detection. Probing produced a number of changes in nonverbal behavior, several of which differed between deceivers and truthtellers. Probing may have communicated suspicion or uncertainty; therefore, deceptive sources were motivated to control their nonverbal demeanor to mask deception-related cues and appear truthful. Probing did not improve detection. Instead, probing receivers considered all sources more truthful. It is suggested that suspiciousness and prior knowledge may affect probing's efficacy.     

Roads and roadblocks to dual commitment: Similar and dissimilar antecedents of union and company commitment

Dual commitment received wide attention during the 1950s and, after a waning of interest during the 1960s and 1970s, interest has grown anew. In this study of dual commitment we used a model of investment and returns, applied referent theory to it, and grounded the investigation in an industrial relations context at an airline carrier in order to examine both company and union commitment. We found that wages were a positive income elastic good with respect to company commitment, but they were a negative good with respect to union commitment. Information obtained from the firm or the union also resulted in divergencies in the commitments. External labor market variables were unrelated to union commitment, but they were related to company commitment. Finally, job influence and perceptions concerning a labor-management program were positive predictors of the two commitments; as such, they have implications for the way firms and unions may want to build dual commitment.

Specifying and facilitating family involvement in services to persons with developmental disabilities

This paper recognizes the important role of family involvement in services to people with developmental disabilities. The paper presents a conceptualization of involvement that was an outcome of a qualitative study of involvement from the perspective of family members themselves. The authors identify a framework of family involvement the composition of which incorporates four system levels (i.e. the individual, program/agency, community, society) and the five role opportunities for family members (i.e. treatment agent, planner, advocate, evaluator, and consultant/educator). Barriers to involvement are then delineated and the authors autline a process for promoting family involvement: 1) contracting for involvement; 2) developing a support system for involvement; and 3) monitoring and evaluating involvement.Presented at the Fourth Annual Conference of The Michigan Chapter, National Association of Social Workers, May 14, 1988.

The college student-athlete: psychological considerations and interventions

This article reviews the literature dealing with problems brought by student-athletes to college counseling and mental health centers. Among the issues discussed are fear of success; identity conflict; social isolation; poor athletic performance; academic problems; and career or vocational concerns. In addition, the authors examine the paradox that although athletes experience as much or more psychological distress as nonathletes, research indicates that athletes use professional services less often than nonathletes. Finally, the authors review approaches to psychological intervention, including short-term psychotherapy, very brief interventions, cognitive behavioral therapy, and career/vocational counseling, and discuss special considerations for conducting therapy with athletes.
