The mediating influence of role stressors in the relationship between mentoring and job attitudes

This study investigated the influence of two role stressors—role ambiguity and role conflict—on previously established relationships between mentoring activities—vocational support, psychosocial support, and role modeling—and prominent job attitudes. Full and partial mediation models were tested with a sample of 355 protégés. Results showed that both role conflict and role ambiguity completely mediated the relationships between psychosocial support and role modeling with job attitudes. There was also support for role conflict as a partial mediator of the relationship between vocational support and job attitudes. Additional analyses revealed that psychosocial support served as a suppressor-variable in this study. Implications for future research and mentoring practice are discussed.     

Blurring boundaries: Correlates of integration and segmentation between work and nonwork

This study investigates the interrelations among role integration-segmentation, role identification, reactions to interruptions, and work-life conflict. Results from a field survey of university staff employees suggest that as highly identified roles are integrated into other domains, high role integration is related to less negative reactions to interruptions, and employees who integrate work into nonwork set fewer boundaries for using communication technologies during nonwork time and report higher work-life conflict. Findings from this research provide insight into how individuals integrate their work and life domains and the consequences of such integration to work-life conflict.     

Vicissitudes in adult life resulting from traumatic experiences in adolescence1

The author deals with the diffi culties in combining the concepts of trauma and phantasy. He evaluates Freudian observations relating to chance and trauma. He considers traumatic effects of chance in relation to the rupture of a narcissistic phantasy of invulnerability. The narrating of traumatic events may awaken in the analyst tendencies to repeat the aggression of these traumatic events towards the subject. The accusatory interpretation can be one of the means by which this repetition is established. The author explores a type of trauma which is essentially related to the disturbance of the structure which contains the ideals of the subject. This disturbance is a consequence of disillusionment resulting from the loss of an object who was the depository of these ideals. Trauma generates a state of mourning for lost ideals. The author describes traumatic events which occurred in a patient's life at puberty; paradoxical behaviours in the patient's parents caused the patient to have new traumas. The reluctance to explore the derivatives of the unconscious, and to investigate possible meaning in symbols, was a central problem in this patient's analysis. The author discusses disturbances in symbolization, and he examines the subject of projective identifi cations that were received by patients from their primary objects.     

American and Chinese College Students’ Anticipations of Their Postgraduate Education, Career, and Future Family Roles

American and Chinese college students’ anticipations showed no gender differences in their desires for postgraduate education, marriage, and parental status. Stereotypical gender differences emerged in both countries when caregiving roles were considered: Both men and women rated it more likely for women than for men to quit their jobs to be caregivers. Overall, male college students, the Chinese men in particular, felt less comfortable than did women in situations where their spouses were superior in earnings, achievements, and social status. More Chinese than American students planned to enter marriage and parenthood at a later age, and the Chinese students rated the importance of family lower. These findings are discussed in light of the general sociocultural model and the role distribution theory.This study was supported partially by a summer mini-grant issued by the University of St. Francis in 2000.     

Theory and Method of Marriage Therapy in Contemporary Africa

This paper describes the theory and practice of marriage therapy in use by the author in his marital therapy process across two regions of Africa. The approach is grounded on an inclusive theoretical perspective inspired by the notion of the basic virtues of a healthy marriage as understood in Africa, and the place of the role theory approach in intervening between opposing parties. The theme developed is that a viable contemporary African marriage therapy practice is derivable from this indigenous model. The major discussion highlights the key guiding orientations and processes in implementing such a practice. A comparative view of the Euro-American emphasis in couple therapy is presented as a background for identifying the difference between the Western and the African perspectives.An initial version of the paper was presented as a Guest Lecture to the members of Staff and Graduate Students of the School of Psychology of the University of KwaZulu-Natal, in Durban, South Africa. The author is grateful to Prof. Inge Petersen and her team of staff of the school for their invitation and encouragement.     

Which statistical formats facilitate what decisions? The perception and influence of different statistical information formats

Research suggesting both a superiority of frequencies over single‐event probabilities and of smaller reference classes over very large reference classes have utilized tasks that vary in computational complexity. The present research sought to simply and directly evaluate if—apart from simplifying statistical inference tasks—frequencies and small reference classes are clearer than other formats. After eliminating possible computational confounds, simple frequencies (based on small reference classes, e.g. 1/3) and to some extent relative frequencies (percentages, e.g. 33%) were perceived as clearer than absolute frequencies (based on very large reference classes, e.g. 90 million Americans) and single‐event probabilities (e.g. 0.33). Concurrently, these different formats were evaluated in terms of their relative influence. Absolute frequencies were relatively more persuasive for smaller magnitudes (e.g. 2.7 million) but less persuasive for larger magnitudes (e.g. 267 million), as compared to analogous presentations. Single‐event probabilities were judged to minimize the significance of information. Copyright © 2002 John Wiley & Sons, Ltd.     

Young children's use of prosody in sentence parsing

Korean children's ability to use prosodic phrasing in sentence comprehension was studied using two types of ambiguity. First, we examined a word-segmentation ambiguity in which placement of the phrasal boundary leads to different interpretations of a sentence. Next, we examined a syntactic ambiguity in which the same words were differently grouped into syntactic phrases by prosodic demarcation. Children aged 3 or 4 years showed that they could use prosodic information to segment utterances and to derive the meaning of ambiguous sentences when the sentences only contained a word-segmentation ambiguity. However, even 5- to 6-year-old children were not able to reliably resolve the second type of ambiguity, an ambiguity of phrasal grouping, by using prosodic information. The results demonstrate that children's difficulties in dealing with structural ambiguity are not due to their inability to use prosodic information.     

Posttraumatic stress disorder and psychosocial functioning within two samples of MVA survivors

To examine criterion F variables of PTSD, the psychosocial functioning of two samples of motor vehicle accident (MVA) survivors was investigated. Within each sample, comparisons between MVA survivors with and without PTSD were conducted on four psychosocial functioning indices at three time points. In addition, the relationships between specific PTSD symptom clusters and psychosocial functioning indices were examined. The study revealed that, in general, MVA survivors with PTSD evidenced poorer psychosocial functioning than did survivors without PTSD. The emotional numbing symptoms of PTSD emerged as the most consistent predictors of the psychosocial functioning indices. The implications of these findings to the comprehensive treatment of PTSD are discussed.     

Probing Lexical Ambiguity: Word Vectors Encode Number and Relatedness of Senses

Lexical ambiguity—the phenomenon of a single word having multiple, distinguishable senses—is pervasive in language. Both the degree of ambiguity of a word (roughly, its number of senses) and the relatedness of those senses have been found to have widespread effects on language acquisition and processing. Recently, distributional approaches to semantics, in which a word's meaning is determined by its contexts, have led to successful research quantifying the degree of ambiguity, but these measures have not distinguished between the ambiguity of words with multiple related senses versus multiple unrelated meanings. In this work, we present the first assessment of whether distributional meaning representations can capture the ambiguity structure of a word, including both the number and relatedness of senses. On a very large sample of English words, we find that some, but not all, distributional semantic representations that we test exhibit detectable differences between sets of monosemes (unambiguous words; N = 964), polysemes (with multiple related senses; N = 4,096), and homonyms (with multiple unrelated senses; N = 355). Our findings begin to answer open questions from earlier work regarding whether distributional semantic representations of words, which successfully capture various semantic relationships, also reflect fine-grained aspects of meaning structure that influence human behavior. Our findings emphasize the importance of measuring whether proposed lexical representations capture such distinctions: In addition to standard benchmarks that test the similarity structure of distributional semantic models, we need to also consider whether they have cognitively plausible ambiguity structure.     

Practice makes perfect: Training the interpretation of emotional ambiguity

The interpretation of emotionally ambiguous words, sentences, or scenarios can be altered through training procedures that are collectively called cognitive bias modification for interpretation (CBM-I). In three experiments, we systematically manipulated the nature of the training in order to discriminate between emotional priming and ambiguity resolution accounts of training effects. In Experiment 1 participants completed word fragments that were consistently related to either a negative or benign interpretation of an ambiguous sentence. In a subsequent semantic priming task they demonstrated an interpretation bias, in that they were faster to identify relatedness of targets that were associated with the training-congruent meaning of an emotionally ambiguous homograph. We then manipulated the training sentences to show that interpretation bias was eliminated when participants simply completed valenced word fragments following unrelated sentences (Experiment 2), or completed fragments that were related to emotional but unambiguous sentences (Experiment 3). Only when participants were required to actively resolve emotionally ambiguous sentences during training did changes in interpretation emerge at test. Findings suggest that CBM-I achieves its effects by altering a production rule that aids the selection of meaning from emotionally ambiguous alternatives, in line with an ambiguity resolution account.
