The role of employee loyalty and formality in voicing discontent

This study extends prior research on voice, loyalty, and postvoice outcomes by examining a variety of methods by which an employee may choose to voice a dispute. The authors argue that more loyal employees may prefer and use less formal methods to voice discontent and that the use of less formal voice methods relates to less job search activity and lower intent to quit. This study also investigated the interrelation between loyalty, voice method, and satisfaction with the attempt to resolve the dispute. Findings from a sample of university staff employees (N = 452) provide support for the hypotheses.     

The Minnesota Multiphasic Personality Inventory-2 across the human immunodeficiency virus spectrum

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) was used to assess individuals' patterns of psychological symptoms across the spectrum of HIV illness. Two hundred and twenty-five participants in the present sample were administered the MMPI-2, 61 were HIV-seronegative controls, 61 were asymptomatic, 36 were symptomatic, and 67 met criteria for AIDS. Symptomatic HIV-seropositive patients scored higher on the Hypochondriasis, Conversion-Hysteria, and Depression Scales. These differences appeared to be largely due to an increase in somatic complaints rather than an increase in other depressive symptoms. Group differences did not appear to be due to HIV-associated neuropsychological dysfunction. Interpretive strategies for the MMPI-2 and treatment considerations are discussed.     

Frequency versus probability formats in statistical word problems

Three experiments examined people's ability to incorporate base rate information when judging posterior probabilities. Specifically, we tested the (Cosmides, L., & Tooby, J. (1996). Are humans good intuitive statisticians after all? Rethinking some conclusions from the literature on judgement under uncertainty. Cognition, 58, 1-73) conclusion that people's reasoning appears to follow Bayesian principles when they are presented with information in a frequency format, but not when information is presented as one case probabilities. First, we found that frequency formats were not generally associated with better performance than probability formats unless they were presented in a manner which facilitated construction of a set inclusion mental model. Second, we demonstrated that the use of frequency information may promote biases in the weighting of information. When participants are asked to express their judgements in frequency rather than probability format, they were more likely to produce the base rate as their answer, ignoring diagnostic evidence.     

What Do Youth Referred for Anxiety Problems Worry About? Worry and Its Relation to Anxiety and Anxiety Disorders in Children and Adolescents

This study examined worry and the parameters of worry that may be associated with clinical anxiety in a sample of 119 children and adolescents referred to a childhood anxiety disorders specialty clinic. Using an interviewing procedure, results indicated that the types of worries reported by the children were similar to those reported in previous studies of nonreferred community children. Also similar to previous community studies were findings showing moderate but significant correlations between different indices of worry (i.e., number, intensity, and frequency of the worries) and children's scores on self-rating scales of anxiety. Results further indicated that worry contributed additional variance beyond that of anxiety in predicting fear. In addition, intensity differentiated clinic children's worries from nonreferred children's. Intensity, and number of worries differentiated subsamples of children within the clinic-referred sample (i.e., children with overanxious disorder or generalized anxiety disorder and children with simple phobia). The importance of examining children's worries to further understand anxiety and its disorders in youth is discussed.     

Relative efficacy of methylphenidate and behavior modification in hyperkinetic children: An interim report

Children reported to be hyperactive in school and with behavior difficulties at home were randomly assigned to methylphenidate, behavior therapy and placebo, or behavior therapy with methylphenidate for an 8-week period. Rating scales were obtained from teachers and parents. Independent blind observers rated childrens' classroom behavior on a weekly basis. A behavior therapy program was implemented in the home and at school. Methylphenidate dosage was individualized. Ratings of behavior deviance were significantly reduced by all treatments. However, a significant advantage for the groups receiving methylphenidate was found over the group receiving behavior therapy and placebo. No significant differences between methylphenidate alone and methylphenidate combined with behavior therapy were obtained. Global ratings of improvement done by teachers favored the combined treatment of behavior therapy and methylphenidate over behavior therapy and placebo. No differences among treatments were found in the mothers' global ratings of improvement. The results indicate that though all three treatments were effective, methylphenidate was significantly superior to behavior therapy alone.This study was supported in part by grant MH 18579, and by grant No. 3-621 from the Long Island Jewish-Hillside Medical Center. The authors wish to thank the behavior therapists, Drs. Jeffrey Felixbrod and Marion Pheterson, as well as Ms. Patricia Ramsey, who was responsible for data analysis.     

Dyslexia linked to talent: global visual-spatial ability

Dyslexia has long been defined by deficit. Nevertheless, the view that visual-spatial talents accompany dyslexia has grown, due to reports of individuals with dyslexia who possess visual-spatial strengths, findings of elevated incidence of dyslexia in certain visual-spatial professions, and the hypothesis that left-hemisphere deficits accompany right-hemisphere strengths. Studies have reported superior, inferior, and average levels of visual-spatial abilities associated with dyslexia. In two investigations, we found an association between dyslexia and speed of recognition of impossible figures, a global visual-spatial task. This finding suggests that dyslexia is associated with a particular type of visual-spatial talent-enhanced ability to process visual-spatial information globally (holistically) rather than locally (part by part).     

A multimethodological analysis of cumulative risk and allostatic load among rural children

This study merged two theoretical constructs: cumulative risk and allostatic load. Physical (crowding, noise, housing quality) and psychosocial (child separation, turmoil, violence) aspects of the home environment and personal characteristics (poverty, single parenthood, maternal highschool dropout status) were modeled in a cumulative risk heuristic. Elevated cumulative risk was associated with heightened cardiovascular and neuroendocrine parameters, increased deposition of body fat, and a higher summary index of total allostatic load. Previous findings that children who face more cumulative risk have greater psychological distress were replicated among a sample of rural children and shown to generalize to lower perceptions of self-worth. Prior cumulative risk research was further extended through demonstration of self-regulatory behavior problems and elevated learned helplessness.
