Validation of a Self-Concept Scale for Lynch Syndrome in Different Nationalities

Learning about hereditary cancer may influence an individual’s self-concept, which otherwise represents a complex but stable cognitive structure. Recently, a 20-statement self-concept scale, with subscales related to stigma-vulnerability and bowel symptom-related anxiety, was developed for Lynch syndrome. We compared the performance of this scale in 591 mutation carriers from Denmark, Sweden and Canada. Principal component analysis identified two sets of linked statements—the first related to feeling different, isolated and labeled, and the second to concern and worry about bowel changes. The scale performed consistently in the three countries. Minor differences were identified, with guilt about passing on a defective gene and feelings of losing one’s privacy being more pronounced among Canadians, whereas Danes more often expressed worries about cancer. Validation of the Lynch syndrome self-concept scale supports its basic structure, identifies dependence between the statements in the subscales and demonstrates its applicability in different Western populations.     

The interaction between memorized objects and abrupt onsets in oculomotor capture

Recent evidence has been found for a source of task-irrelevant oculomotor capture (defined as when a salient event draws the eyes away from a primary task) that originates from working memory. An object memorized for a nonsearch task can capture the eyes during search. Here, an experiment was conducted that generated interactions between the presence of a memorized object (a colored disk) with the abrupt onset of a new object during visual search. The goal was to compare memory-driven oculomotor capture to oculomotor capture caused by an abrupt onset. This has implications for saccade programming theories, which have little to say about saccades that are influenced by object working memory. Results showed that memorized objects capture the eyes at nearly the same rate as abrupt onsets. When the abrupt onset and a memorized color coincide in the same object, this combination leads to even greater oculomotor capture. Finally, latencies support the competitive integration model: Shorter saccade latencies were found when the memorized color combined with the onset captured the eyes, as compared to either color or onset only. Longer latencies were also found when the color and onset occurred in the same display but were spatially separated.     

What we remember affects how we see: Spatial working memory steers saccade programming

Relationships between visual attention, saccade programming, and visual working memory have been hypothesized for over a decade. Awh, Jonides, and Reuter-Lorenz (Journal of Experimental Psychology: Human Perception and Performance 24(3):780–90, 1998) and Awh et al. (Psychological Science 10(5):433–437, 1999) proposed that rehearsing a location in memory also leads to enhanced attentional processing at that location. In regard to eye movements, Belopolsky and Theeuwes (Attention, Perception & Psychophysics 71(3):620–631, 2009) found that holding a location in working memory affects saccade programming, albeit negatively. In three experiments, we attempted to replicate the findings of Belopolsky and Theeuwes (Attention, Perception & Psychophysics 71(3):620–631, 2009) and determine whether the spatial memory effect can occur in other saccade-cuing paradigms, including endogenous central arrow cues and exogenous irrelevant singletons. In the first experiment, our results were the opposite of those in Belopolsky and Theeuwes (Attention, Perception & Psychophysics 71(3):620–631, 2009), in that we found facilitation (shorter saccade latencies) instead of inhibition when the saccade target matched the region in spatial working memory. In Experiment 2, we sought to determine whether the spatial working memory effect would generalize to other endogenous cuing tasks, such as a central arrow that pointed to one of six possible peripheral locations. As in Experiment 1, we found that saccade programming was facilitated when the cued location coincided with the saccade target. In Experiment 3, we explored how spatial memory interacts with other types of cues, such as a peripheral color singleton target or irrelevant onset. In both cases, the eyes were more likely to go to either singleton when it coincided with the location held in spatial working memory. On the basis of these results, we conclude that spatial working memory and saccade programming are likely to share common overlapping circuitry.     

The development of computer ethics: Contributions from business ethics and medical ethics

In this essay, we demonstrate that the field of computer ethics shares many core similarities with two other areas of applied ethics, Academicians writing and teaching in the area of computer ethics, along with practitioners, must address ethical issues that are qualitatively similar in nature to those raised in medicine and business. In addition, as academic disciplines, these three fields also share some similar concerns. For example, all face the difficult challenge of maintaining a credible dialogue with diverse constituents such as academicians of various disciplines, professionals, policymakers, and the general public, Given these similarities, the fields of bioethics and business ethics can serve as useful models for the development of computer ethics. A version of this paper was presented at ETHICOMP98, the Fourth International Conference on Ethical Issues of Information Technology, March 25–27, 1998, Erasmus University, the Netherlands. Kenman Wong, Ph.D., is an Associate Professor of Business Ethics; Gerhard Steinke, Ph.D., is Professor of Management and Information Systems.

How color enhances visual memory for natural scenes

We offer a framework for understanding how color operates to improve visual memory for images of the natural environment, and we present an extensive data set that quantifies the contribution of color in the encoding and recognition phases. Using a continuous recognition task with colored and monochrome gray-scale images of natural scenes at short exposure durations, we found that color enhances recognition memory by conferring an advantage during encoding and by strengthening the encoding-specificity effect. Furthermore, because the pattern of performance was similar at all exposure durations, and because form and color are processed in different areas of cortex, the results imply that color must be bound as an integral part of the representation at the earliest stages of processing.     

A model for school psychology practice: addressing the needs of students with emotional and behavioral challenges through the use of an in-school support room and reality therapy

This article describes a treatment approach for students with emotional and behavioral challenges. The approach involves conducting reality therapy in an in-school support room. Data from this pilot study indicate that the treatment assists in developing more effective choices and in turn promotes cognitive and behavioral change in most students, while reducing the number of disciplinary actions for these students.     

Do priming effects in perceptual identification and word judgment reflect different underlying mechanisms?

We examined priming of orthographically illegal nonwords in a perceptual identification task and a word judgment task in undergraduate participants. In perceptual identification, priming was significant and equivalent after structural or phonological encoding. In word judgment, priming was significant after phonological encoding but not structural encoding. In a follow-up experiment in older control participants and amnesic participants, priming in word judgment was not significant. Older control participants found the stimuli more difficult to pronounce than did undergraduate participants, and word judgment priming in undergaduate participants was significant only for the stimuli that were judged easy to pronounce. These findings demonstrate that priming in perceptual identification and word judgment extends to novel stimuli that are not linked to preexisting lexical or sublexical representations but that priming occurs at different levels in the two tasks: at a featural or orthographic level in perceptual identification and at a phonological level in word judgment.     

Organizational partnerships in China: self-interest, goal interdependence, and opportunism

Opportunism in organizational partnerships may be understood in terms of how partners conclude that their self-interests are related to each other. When partners believe that their goals are competitively but not cooperatively related, they are tempted to pursue their self-interests opportunistically. Cognitive understandings and values of a shared vision may help partners believe their goals are cooperatively related. Results from 103 pairs of customer and supplier organizations support the argument that partnerships are not inevitably threatened by opportunism. Using structural equation analysis, the authors suggested that shared vision can help partners develop cooperative goals that lead to low levels of opportunism. These results suggest that a shared vision and cooperative goals are important foundations for effective organizational partnerships.     

Social competence in children of alcoholic parents over time

In the current study, the authors tested the hypothesis that children of alcoholic parents (COAs) show deficits in social competence that begin in early childhood and escalate through middle adolescence. Teachers, parents, and children reported on the social competence of COAs and matched controls in a community sample assessed from ages 6 to 15. Hierarchical linear growth models revealed different patterns of change in social competence across development as a function of the reporter of various indicators of competence. Moreover, female COAs showed deficits in social competence in early childhood that receded in adolescence and that varied across subtypes of parent alcoholism. Implications of these findings for understanding the development of social competence in children, and at-risk children in particular, are discussed.
