Working memory representations persist in the face of unexpected task alterations

It is well known that information can be held in memory while performing other tasks concurrently, such as remembering a color or number during a separate visual search task. However, it is not clear what happens to stored information in the face of unexpected tasks, such as the surprise questions that are often used in experiments related to inattentional and change blindness. Does the unpredicted shift in task context cause memory representations to be cleared in anticipation of new information? To answer this question, we ran two experiments where the task unexpectedly switched partway through the experiment with a surprise question. Half of the participants were asked to report the same attribute (Exp. 1?=?Identity, Exp. 2?=?Color) of a target stimulus in both presurprise and postsurprise trials, while for the other half, the reported attribute switched from identity to color (Exp. 1) or vice versa (Exp. 2). Importantly, all participants had to read an unexpected set of instructions and respond differently on the surprise trial. Accuracy on the surprise trial was higher for the same-attribute groups than the different-attribute groups. Furthermore, there was no difference in reaction time on the surprise trial between the two groups. These results suggest that information participants expected to report can survive an encounter with an unexpected task. The implication is that failures to report information on a surprise trial in many experiments reflect genuine differences in memory encoding, rather than forgetting or overwriting induced by the surprise question.     

Brief motivational intervention with homeless adolescents: evaluating effects on substance use and service utilization.

A brief motivational intervention with 117 homeless adolescents was evaluated using a randomized design and 3-month follow-up. The intervention was designed to raise youths' concerns about their substance use, support harm reduction, and encourage greater service utilization at a collaborating agency. The study was designed to strengthen initial promising results of an earlier study (P. L. Peterson, J. S. Baer, E. A. Wells, J. A. Ginzler, & S. B. Garrett, 2006). Several modifications in the clinical protocol were included to enhance engagement with the intervention. Analyses revealed no significant benefits for intervention participants when homeless youths' substance use rates were compared with those of control participants. Service utilization during the intervention period increased for those receiving the intervention but returned to baseline levels at follow-up. Participants reported overall reductions in substance use over time. Differences between sampling methods for the current and previous study are discussed, as are the limitations of brief interventions with this population. Future research needs to elucidate mechanisms of change and service engagement for highly vulnerable youth.     

Knowledge cannot explain the developmental growth of working memory capacity

According to some views of cognitive growth, the development of working memory capacity can account for increases in the complexity of cognition. It has been difficult to ascertain, though, that there actually is developmental growth in capacity that cannot be attributed to other developing factors. Here we assess the role of item familiarity. We document developmental increases in working memory for visual arrays of English letters versus unfamiliar characters. Although letter knowledge played a special role in development between the ages of 6 and 8 years, children with adequate letter knowledge showed practically the same developmental growth in normalized functions for letters and unfamiliar characters. The results contribute to a growing body of evidence that the developmental improvement in working memory does not wholly stem from supporting processes such as encoding, mnemonic strategies, and knowledge.

Targeting low career confidence using the career planning confidence scale

The authors describe the development and validation of a test of career planning confidence that makes possible the targeting of specific problem issues in employment counseling. The scale, developed using a rational process and the authors' experience with clients, was tested for criterion‐related validity against 2 other measures. The scale produced a 6‐factor structure that replicates common career planning models: Readiness to Make a Career Decision, Self‐Assessment, Generating Options, Information Seeking, Deciding, and Implementing a Decision. Validity and reliability of the scale are discussed, along with suggestions for employment counseling practice.     

Hume’s naturalistic theory of representation

Hume is a naturalist in many different respects and about many different topics; this paper argues that he is also a naturalist about intentionality and representation. It does so in the course of answering four questions about his theory of mental representation: (1) Which perceptions represent? (2) What can perceptions represent? (3) Why do perceptions represent at all? (4) Howdo perceptions represent what they do? It appears that, for Hume, all perceptions except passions can represent; and they can represent bodies, minds, and persons, with their various qualities. In addition, ideas can represent impressions and other ideas. However, he explicitly rejects the view that ideas are inherently representational, and he implicitly adopts a view according to which things (whether mental or non-mental) represent in virtue of playing, through the production of mental effects and dispositions, a significant part of the causal and/or functional role of what they represent. It is in virtue of their particular functional roles that qualitatively identical ideas are capable of representing particulars or general kinds; substances or modes; relations; past, present, or future; and individuals or compounds.     

Organizational Attractiveness of Foreign‐Based Companies: A country of origin perspective

Attracting high‐quality applicants is a crucial activity for the success of an organization. In today's globalized world, multinational enterprises need to attract talent not only in the domestic market but also in overseas markets. This exploratory study introduces the country of origin image framework from marketing literature to the context of recruitment in order to examine why foreign companies are (not) attractive to local job seekers, exemplified by the case of Japanese and US companies in Vietnam. Survey results of more than 300 participants confirmed the robustness of our postulated framework. Symbolic images such as the technological development and images of people of a country predicted the attractiveness of foreign companies above and beyond instrumental images of job characteristics. Detailed explanations and practical implications are provided.
