A shift in task routines during the learning of a motor skill: group-averaged data may mask critical phases in the individuals' acquisition of skilled performance

The authors describe a transient phase during training on a movement sequence wherein, after an initial improvement in speed and decrease in variability, individual participants' performance showed a significant increase in variability without change in mean performance speed. Subsequent to this phase, as practice continued, variability again decreased, performance significantly exceeded the gains predicted by extrapolation of the initial learning curve, the type of errors committed changed, and performance became more coherent. The transient phase of increased variability may reflect a mixture of 2 (or more) performance routines before the more effective one is set and mastered, presumably the setting up of a sequence-specific representation. Both group and individual analyses indicated a departure from the single process (e.g., power-law) model of learning. However, although similar phases appeared in the mean group data, there was little correspondence to individual participants' time courses, and the individuals' gains in the second low-variability phase were masked.     

Sex differences in mate preferences revisited: do people know what they initially desire in a romantic partner?

In paradigms in which participants state their ideal romantic-partner preferences or examine vignettes and photographs, men value physical attractiveness more than women do, and women value earning prospects more than men do. Yet it remains unclear if these preferences remain sex differentiated in predicting desire for real-life potential partners (i.e., individuals whom one has actually met). In the present study, the authors explored this possibility using speed dating and longitudinal follow-up procedures. Replicating previous research, participants exhibited traditional sex differences when stating the importance of physical attractiveness and earning prospects in an ideal partner and ideal speed date. However, data revealed no sex differences in the associations between participants' romantic interest in real-life potential partners (met during and outside of speed dating) and the attractiveness and earning prospects of those partners. Furthermore, participants' ideal preferences, assessed before the speed-dating event, failed to predict what inspired their actual desire at the event. Results are discussed within the context of R. E. Nisbett and T. D. Wilson's (1977) seminal article: Even regarding such a consequential aspect of mental life as romantic-partner preferences, people may lack introspective awareness of what influences their judgments and behavior.     

The attachment system in fledgling relationships: an activating role for attachment anxiety

Is it sensible to study attachment dynamics between potential romantic partners before they share a full-fledged attachment bond? The present data indicate that such an approach may reveal novel insights about initial attraction processes. Four studies suggest that the state-like experience of attachment anxiety has functional implications within fledgling (i.e., desired or undeveloped) romantic relationships, well before the formation of an attachment bond. Studies 1 and 3 reveal that attachment anxiety directed toward a particular romantic interest is elevated before (in comparison with after) participants report being in an established relationship. Studies 2 and 3 demonstrate that such partner-specific attachment anxiety predicts attachment-relevant outcomes in fledgling relationships, including proximity seeking, safe haven, secure base, passionate love, and other approach behaviors. These associations were reliable above and beyond (and were typically as strong as or stronger than) the effect of sexual desire. Finally, Study 4 presents evidence that partner-specific attachment anxiety may cause several of these attachment-relevant outcomes. Attachment anxiety seems to be a normative experience and may signal the activation of the attachment system during the earliest stages of romantic relationships.     

Internationalizing the counseling psychology curriculum: toward new values,competencies, and directions

The changing world in which we now live requires that counseling psychology alter its training curriculum assumptions, content, and methods to prepare students and faculty for meeting the challenges of life in the global community. Global problems such as poverty, migration, overpopulation, international war and violence, rapid urbanization, and cultural disintegration are posing new challenges for service professions that are no longer suited to ethnocentric values, content, and interventions. Adjustment syndromes such as alienation, culture shock, acculturation, identity conflict and confusion, and migration stress are now emerging as major problems for counselors in schools, colleges, industry, clinics and private practice. New competencies are needed. The present article offers 50 different ways to assist in the internationalization of the counseling curriculum, with specific recommendations for professional psychological associations and department of psychology curriculum content and extra-curricular activities, and universities. The article calls upon counseling psychologists around the world to help create a new professional and global consciousness that can advance our field by addressing the problems we face and restoring dignity to those we serve through the provision of more informed and culturally sensitive services.     

Aspects of Repetition in Bonobo–Human Conversation: Creating Cohesion in a Conversation Between Species

Ape language research has primarily focused on specific isolated language features. In contrast, in research into human language, traditions such as conversational analysis and discourse analysis propose to study language as actual discourse. Consequently, repetitions are seen as accomplishing various discursive and pragmatic functions in human conversations, while in apes, repetitions are seen as rote imitations and as proof that apes do not exhibit language. Tools from discourse analysis are applied in this study to a conversation between a language-competent bonobo, Pan paniscus and a human. The hypothesis is that the bonobo may exhibit even larger linguistic competency in ordinary conversation than in controlled experimental settings. Despite her limited productive means, the bonobo Panbanisha competently engages in co-constructing the conversational turns. She uses shared knowledge and repetitions to achieve compliance with a request. This reveals a knowledge about socio-linguistic interactions which goes beyond the pure informational content of words.

Importance of shared genes and shared environments for symptoms of depression in older adults.

The Center for Epidemiologic Studies-Depression scale was administered to 68 identical and 161 fraternal twin pairs reared apart and 114 identical and 138 fraternal pairs reared together to ascertain relative genetic and environmental contributions to individual differences in self-reported depressive symptoms. Intraclass correlations and model fitting indicated that genetic influences explained 16% of the variance in total depression scores and 19% for the Psychomotor Retardation and Somatic Complaints subscale, but heritability was minimal for the Depressed Mood and Well-Being subscales. Influence of family rearing context played a substantial role in explaining twin similarity, whereas unique life experiences accounted for the greatest proportion of variance. Significant age group differences were observed, with heritability greater in twins of 60 years of age or older than in twins under 60, especially for Psychomotor Retardation.     

Managing computer integrated manufacturing (CIM): A review of themes,issues, and practices

Large scale changes from traditional to computer integrated manufacturing (CIM) make fundamental alterations in the way work gets done in an organization. The incorporation of sophisticated computerized machinery into the work flow, however, is only the catalyst for a range of human resource and organizational issues. A review of the literature suggests that the management of these issues in the transition from traditional to computerized systems is critical to success. The review is presented within a time frame that encompasses the major themes of a CIM change effort. These themes include the decision phase or automation consideration, the developmental phase, the bridging phase that spans the gap between planning and implementation, and the implementation phase. Important management issues are summarized at each step, including cost justification, management commitment, planning, vendor and union relationships, employee resistance, education and training, job redesign, and organizational restructuring. Wherever applicable, specific practices and real-world examples for effectively managing these issues are presented.
