Reasons for employee sabotage in the workplace

Unionized workers at a factory were asked to rate a variety of reasons which would justify the use of sabotage in an organization, as well as the justifiability of four general methods of sabotage (slowdowns, destructiveness, dishonesty, and causing chaos). Results showed that as compared to those who didn't accept a wide variety of reasons for sabotage, those who accepted a variety of reasons would more readily justify all forms of sabotage except dishonesty. The data is discussed in terms of the reasons for the lack of justification that dishonesty receives, as well as future directions for the study of sabotage.     

Testing the limits of the phonetic mnemonic system

Three experiments tested the efficacy of the phonetic mnemonic system under varying conditions of application. The first study attempted unsuccessfully to replicate and extend the work of Morris and Greer (1984), who had shown training in the phonetic mnemonic method to facilitate memorization of a serial list of two-digit numbers. In the present study, subjects trained in the phonetic mnemonic method failed to learn lists of two-, four-, and six-digit numbers better than control subjects. The second experiment partially replicated the first, the differences being that training in the phonetic mnemonic method was strengthened, and time allotted for number recall was extended. Under these circumstances the phonetic mnemonic group recalled the two-, four-, and six-digit numbers significantly better than the control groups, a finding conforming with Morris and Greer's (1984) results. The third experiment partially replicated the second, everything being the same except that, in this case, subjects constructed their own key words representing each number, instead of these words being supplied by the experimenter. Under these conditions, subjects trained in the phonetic mnemonic method recalled significantly fewer numbers than control subjects.     

Perceptual organization of acoustic stimuli by budgerigars (Melopsittacus undulatus): II. Vocal signals

Operant conditioning and multidimensional scaling procedures were used to study auditory perception of complex sounds in the budgerigar. In a same-different discrimination task, budgerigars learned to discriminate among natural vocal signals. Multidimensional scaling procedures were used to arrange these complex acoustic stimuli in a two-dimensional space reflecting perceptual organization. Results show that budgerigars group vocal stimuli according to functional and acoustical categories. Studies with only contact calls show that birds also make within-category discriminations. The acoustic cues in contact calls most salient to budgerigars appear to be quite complex. There is a suggestion that the sex of the signaler may also be encoded in these calls. The results from budgerigars were compared with the results from humans tested on some of the same sets of complex sounds.     

The biparental care system of the California mouse, Peromyscus californicus

Most knowledge of parent-offspring relations in mammals is derived from studies of mother-infant interactions. Male parental care has been less well studied. We explored maternal and paternal behavior of the California mouse, Peromyscus californicus. Six pairs of parents and their young were videotaped continuously for 12 hours/day, on alternate days from Days 1 to 31 postpartum. Males exhibit all parental activities and to the same extent as displayed by mothers, except lactation. Male parental behavior begins on the day of birth. Mothers and fathers spend substantial and equivalent amounts of time in the nest and in physical contact with pups throughout lactation. Males devote more time than females to licking pups, although females engage in more pup anogenital licking. Mothers nurse for at least 4 weeks, and fathers and mothers both build nests and carry young. The biparental care system of Peromyscus californicus affords an opportunity to develop a broader, more complete view of parent-offspring relations.     

Psychosocial risk factors, natural immunity, and cancer progression: Implications for intervention

One of the more important and emerging fields in which psychologists collaborate with other disciplines is psychoimmunology. Centuries of clinical anecdote and decades of psychosomatic hypotheses have gained credibility in the eyes of the medical establishment—and many patients—by the systematic investigation of mechanisms potentially explaining how events intrapsychic and interpersonal could affect physical disease processes. The central nervous system is connected with the immune system by both neuronal and endocrinological pathways. The immune system has been found to mediate the organism’s response to aberrations of its own normal functions, as well as to invading organisms from without. AIDS, arthritis, asthma, lupus, and herpes are some of the illnesses in which research is demonstrating important relationships among psychosocial and immunological factors and disease course. In this article, we first discuss the immunological apparatus in order to provide a base for subsequent discussions of the effects of stress on immune function. Then we discuss malignant diseases and current evidence that disease course is related to both psychosocial stressors and immune function. We next discuss a model of these interactions, and finally we talk about interventions incorporating psychosocial factors aimed at influencing immune status and, thus, disease course.     

Acquisition of word-processing skills by younger, middle-age, and older adults

A total of 45 subjects in three age groups (younger, middle-age, older) were trained to word process on microcomputers using a commercial training program and an experimenter-designed test and evaluation protocol. Although all of the subjects mastered the essentials of word processing, the older group took significantly longer to complete the training and evaluation procedures and performed more poorly on a review examination that tested their knowledge of the word-processing commands and techniques. The results are discussed in relation to requirements for trainer assistance, motivational factors, and the need to design training protocols that meet the needs of older adults.     

Radial localization in the aged

Elderly subjects were 41% less accurate than young subjects in localizing a point in the frontal plane. The decline could be ascribed neither to an age difference in image formation or skill acquisition nor to a difference in motivational level or trace retention. Evidently the "ambient" or "transient" visual system is compromised at an elementary level. Reasons why this deficit may not be compounded at more complex levels of spatial processing are suggested.     

The assessment of type a behavior in children and adolescents: An overview

The present article presents an overview of the instruments that have been used to assess the Type A behavior pattern in children and adolescents. The development, usage, and psychometric properties of each assessment technique are discussed, with methodological concerns being addressed whenever appropriate. The Matthews Youth Test for Health is the assessment of choice for children, because of its brevity, ease of administration, and adequate psychometric properties. The Hunter-Wolf A-B Rating Scale is desirable only for older, highly literate children. The Adolescent Structured Interview appears to be the most promising device for the adolescent age range. The other adolescent assessment devices are relatively unpopular, difficult to administer, and not always conceptually parallel to existing research on Type A behavior. Recommendations for future research are presented.
