What causes scale errors in children?

A recent article by DeLoache et al. has documented an intriguing phenomenon in the development of action planning in young children. When children act on toy replicas of larger objects they make scale errors that are consistent with the full-sized object. Although the actions selected are inappropriate, their execution accurately takes into account the true size of the target. This phenomenon permits tests of the predictions of the perception-action and planning-control models of vision for action.     

Visual illusions affect planning but not control

Much debate has arisen over how to account for the pattern of effects of visual illusions on action - that is, the findings that illusions affect actions in some circumstances but not others. I propose that this pattern can best be explained by postulating that visual illusions affect the planning of actions but do not affect the on-line control of actions. Strong evidence for this viewpoint comes from recent studies that show 'dynamic illusion effects': a large illusion effect early in a movement, but a decreasing effect as the hand approaches the target. These findings pose difficulties for other models of illusion effects on action.     

Exploring the edges: boundaries and breaks

In this article, we examine conceptual and practical issues pertaining to relationship boundaries within the helping profession. Although our focus is primarily on relationships between mental health professionals and clients, there are considerable implications for a new approach to ethically structuring and understanding the construct of "required distance" in many human-interactive professions, such as teaching, religious leadership, public administration, and others. We define the concept of boundary as applied to human relationships, provide examples of boundary breaks, and raise questions regarding how to evaluate the significance and morality issues raised by specific boundary breaks. Questions and dilemmas are presented regarding boundary setting and accidental or deliberate boundary breaking. Representative dangers present in boundary breaks are identified, and examples are provided. Possible beneficial outcomes are also discussed. Finally, a suggested protocol for assessing a proposed boundary break is provided, much of which is drawn from the work and thinking of Laura Brown, applied more generally in this article, with additions from our perspectives.     

Small-group effectiveness on an administrative task as influenced by knowledge of results and sex composition of the group

Two experiments were designed to investigate some possible extensions to Locke's theory of task motivation and incentives. In experiment 1 (192 Ss) the effect of KR on small-group effectiveness (SGE) was analyzed. The SGE-measurements (productivity and group atmosphere) were based on a subjective operationalization of the concept ?small-group effectiveness'. Five one-way analyses of variance revealed no significant influence of KR on SGE thus supporting Locke's findings. In experiment 2 (64 Ss) homogeneous male groups were compared to homogeneous female groups to find out whether sex composition of the group would have a significant influence on SGE. Five Fisher t-tests revealed no differences between the means of male and female groups. In this case, too, Locke's theory was supported. Limitations and implications of these results are discussed.     

Career Decision‐Making Self‐Efficacy Change in Italian High School Students

The authors explored the effects of a structured‐group career intervention among 280 Italian high school students. Hierarchical linear models indicated the intervention's effectiveness in increasing career decision‐making self‐efficacy and, consequently, career exploration, but not in decreasing career choice anxiety. In addition, partial confirmation was found for the moderating effects of participants' expectations and motivation to change on the relationship between career decision‐making self‐efficacy and career choice anxiety. The findings support the development of a systematic vocational guidance program in Italian schools.     

Sexual harassment law: It’s not what you think

Companies and colleges often react strongly to allegations of sexual harassment, even firing men on first offenses, because of their fear of lawsuits. A review of sixty-two federal Courts of Appeals decisions in sexual harassment cases indicates that sexual harassment law is not as broad as suggested by these strong reactions.
