Rotating With Rotated Text: A Natural Behavior Approach to Investigating Cognitive Offloading

Determining how we use our body to support cognition represents an important part of understanding the embodied and embedded nature of cognition. In the present investigation, we pursue this question in the context of a common perceptual task. Specifically, we report a series of experiments investigating head tilt (i.e., external normalization) as a strategy in letter naming and reading stimuli that are upright or rotated. We demonstrate that the frequency of this natural behavior is modulated by the cost of stimulus rotation on performance. In addition, we demonstrate that external normalization can benefit performance. All of the results are consistent with the notion that external normalization represents a form of cognitive offloading and that effort is an important factor in the decision to adopt an internal or external strategy.     

Catholic Social Teaching as a Framework for Research Ethics

The importance of having ethical oversight in research that is carried out on humans is well established. Research ethics, which is mainly influenced by a biomedical ethical framework, aims to ensure that the well-being and the rights of research participants are upheld and that any potential risks and harms are reduced. However, research is also considered to be a social activity with social effects. Therefore the principles of Catholic Social Teaching as a framework for research ethics may be significant. This paper outlines those principles and demonstrates how these principles may be used for: (1) reflecting ethically on research (i.e. before the project begins), (2) judging a research ethics proposal (i.e. the ethical review) and (3) providing guidelines for action in research (i.e. the implementation of the research project).     

Hide and seek: The theory of mind of visual concealment and search

Researchers have investigated visual search behavior for almost a century. During that time, few studies have examined the cognitive processes involved in hiding items rather than finding them. To investigate this, we developed a paradigm that allowed participants to indicate where they would hide (or find) an item that was to be found (or hidden) by a friend or a foe. We found that (i) for friends more than foes, participants selected the pop-out item in the display, and (ii) when the display was homogeneous, they selected nearby and corner items. These behaviors held for both hiding and finding, although hide and find behaviors were not identical. For pop-out displays, decision times were unusually long when hiding an item from a foe. These data converge on the conclusion that the principles of search and concealment are similar, but not the same. They also suggest that this paradigm will provide researchers a powerful method for investigating theory of mind in adults.     

Assessment of Parenting Practices Related to Conduct Problems: Development and Validation of the Management of Children's Behavior Scale

We report on the development and initial validation of the parent-report scale, Management of Children's Behavior Scale (MCBS), designed to evaluate parenting practices related to conduct problems in children. Children (N=396, ages 2-14) referred for outpatient treatment and their parents served as participants. We evaluated the composition and consistency of the scale and provided evidence pertaining to concurrent, predictive, and incremental validity. Evidence for each type of validity was consistent with the conceptualization of the scale and the pertinence to child conduct problems. The measure also was sensitive to therapeutic changes. Parenting practices targeted in treatment (parent management training) improved as predicted over time. The results suggest the measure may be useful in evaluating parenting practices known to relate to conduct problems and often targeted for intervention in parent- and family-based treatment.     

Effect of brand name on consumers' risk perceptions of online shopping

The purpose of the present study was to investigate the relationship between brand names and consumers' perceived risk. Hypotheses dealt with whether the presence of a product's brand name affects consumers' perceived risk towards shopping online; whether the familiarity with a brand name influences consumers' perceived risk; and whether online shoppers and non‐shoppers perceive risk towards shopping online differently. Results indicate that the presence or absence of a product's brand name affects online shoppers' perceived risk, but in the opposite direction to that expected. There was no significant difference between online shoppers' perceived risk vis‐à‐vis brand familiarity; however, online shoppers possessed lower perceived risk than non‐shoppers. Implications and limitations are discussed and recommendations for future research are provided. Copyright © 2004 Henry Stewart Publications Ltd.     

Interpreting elliptical verb phrases

Elliptical verb phrases are anaphoric expressions whose correct interpretation depends on the exact form of the preceding text as well as its meaning. However, people are not very good at remembering surface details of what they read or hear, so how do they understand such expressions? One alternative to a linguistically based interpretation of elliptical verb phrases is to assign them meanings that are plausible, given general knowledge about the situation being described. In an experiment, subjects read passages in which context provided a plausible interpretation for an elliptical verb phrase that either was or was not at odds with the linguistically correct interpretation. There was a tendency for subjects to assign plausible, but incorrect, meanings to elliptical verb phrases. This tendency increased with the distance between the elliptical verb phrase and its antecedent. Incorrect interpretations were assigned slowly, and the speed of assignment increased with distance from the antecedent. These results suggest that people try to interpret elliptical verb phrases correctly, but that they are not always able to do so. Furthermore, they indicate that the intuition that elliptical verb phrases are easy to interpret is misleading. If text is to be comprehensible, speakers and writers must use such expressions with care.     

Spatial coordinates and reading: Comments on Monk (1985)

Subjects are able to process some texts when they are presented, word-by-word, in a single physical location. As differential spatial information is not available in this task, Monk (1985a) argues that it need not be derived in normal reading. We suggest this conclusion is unwarranted, because subjects make large and very accurate regressive saccades to regions of previously fixated text. Without a representation of spatial coordinates this should not occur.     

Sex roles and the link between fertility and employment

Using a sample of Toronto women, we reexamine the relationship between employment and fertility with the aim of clarifying whether employment status is negatively related to the birth rate only among certain categories of women as defined by sex roles. Especially noteworthy is the finding that employed wives who rate their performance as a spouse and mother as better than most have a birth rate which is as high as that for women who are not in the labor force.The authors are indebted to David Johnson, Susan Welch, and Lynn White of the University of Nebraska, and Gordon Irving of Carleton University for their comments on an earlier version of this article.
