Attention and perception: An information-integration perspective

Attentional effects in perceptual processing are analyzed within a framework of a fuzzy logical model of perception. The recognition of a pattern is conceptualized as involving three stages of processing: featural evaluation, integration of features, and pattern classification. The model predicts no loss of resolution when multiple sources of information are integrated to recognize a perceptual event. This model is contrasted with a single-channel model in which only one source of information can be recognized at a time. The task involves a relatively novel situation of speech perception by ear and eye. No attentional decrement is observed when observers process both auditory and visual speech specifying a single speech event. This result contrasts with previous studies showing a loss when attention has to be divided between different events along auditory and visual modalities. The different results are interpreted in terms of the number of events that have to be processed. Processing two different modalities leads to an attentional decrement when the two inputs specify different events whereas no attentional decrement occurs when these inputs are integrated to recognize a single event. A distinction is made between detection that requires only the evaluation of a single source of information and recognition that requires the evaluation and integration of multiple sources of information. The current framework is also used to discuss previous empirical and theoretical work and the issue of early versus late selection.     

Tense and Truth Conditions

The B-theory of time holds that McTaggart’s A-series of past, present, and future is reducible to the B-series of events running from earlier to later. According to the date-theory—originally put forth by J.J.C. Smart and later endorsed by by D.H. Mellor—the truth conditions of tensed or Asentence-tokens can be given in terms of tenseless or B-sentences and, therefore, A-sentence-tokens do not ascribe any A-determinations of pastness, presentness, or futurity. However, as Nathan Oaklander has argued, the date-theory does not provide an adequate analysis of the ontological truth conditions of irreducible A-propositions. I show that the co-reporting theory—which holds that for every A-sentence-token there is a B-sentence that differs in sense but reports the same event or state of affairs—escapes the objections Oaklander has addressed against the date-theory.     

THE FORUM

Internet plagiarism continues unabated and may even be increasing. Questions pertaining to the ethical-moral construct employed by students to justify Internet plagiarism among high school students have remained relatively untouched. Understanding not simply the prevalence of Internet plagiarism but also the variety of explanations used by students to justify their plagiarism seems crucial to curtailing its practice. In this study, I surveyed 160 high school students and endeavored to understand and describe the practices of students who use the Internet for schoolwork and who engage in copy-paste plagiarism or paper-buying practices. The results indicate that students are more easily able to justify copy-paste plagiarism for a variety of reasons that mirror justifications of other forms of conventional plagiarism. Most students indicated they would never purchase a paper for reasons ranging from fear of getting caught to more principled and nuanced ethical claims. Based on these results I also offer educators suggestions for refining assignments and evaluation methods.     

Unemployment,Self-Esteem,and Depression: A Social Comparison Theory Approach

A social comparison theory approach to the relation between unemployment, self-esteem, and depression was tested using a cross-sectional questionnaire design (N = 88). Personal attributes were used as the domain of comparison, and four types of comparisons-intrapersonal, interpersonal, intragroup, and intergroup-were operationalized. Employment status affected the salience of intrapersonal comparisons. Comparisons with the past self were highly predictive of psychological distress among unemployed respondents, whereas comparisons with the ideal self predicted distress among the employed. Individual-level and group-level social comparisons had different associations with the dependent measures for unemployed respondents. Intrapersonal and interpersonal comparisons were significantly related to depression and self-esteem scores, whereas intragroup and intergroup comparisons were related only to self-esteem. Social comparisons with unemployed people were related to reduced depression levels among employed respondents. Results also showed that unemployed people had more negative social comparison scores relative to their employed counterparts. Results are discussed in terms of recent developments in social comparison theory. Suggestions for future research are outlined.     

Expect the Unexpected? Variations in Question Type Elicit Cues to Deception in Joint Interviewer Contexts

We examined the effect of (i) a second interviewer's demeanour and (ii) asking expected and unexpected questions on cues to deception. We predicted that liars compared with truth tellers would provide more detail to expected questions and less detail to unexpected questions, particularly when the second interviewer is supportive. Liars prepare answers for expected questions, and a supportive interviewer will encourage them to provide more detail. By definition, liars have not prepared answers for unexpected questions, and their answers to such questions will be less detailed. Participants (N = 168) appeared before two interviewers: The first asked all the questions, and the second remained silent. The second interviewer exhibited either a supportive or a neutral demeanour. As predicted, liars provided more detail to expected questions and less detail to unexpected questions, particularly when the second interviewer was supportive. In conclusion, a supportive second interviewer elicits cues to deceit. Copyright © 2013 John Wiley & Sons, Ltd.     

Richard (Routley) Sylvan: Writings on Logic and Metaphysics

Richard Sylvan (né Routley) was one of Australasia's most prolific and systematic philosophers. Though known for his innovative work in logic and metaphysics, the astonishing breadth of his philosophical endeavours included almost all reaches of philosophy. Taking the view that very basic assumptions of mainstream philosophy were fundamentally mistaken, he sought radical change across a wide range of theories. However, his view of the centrality of logic and recognition of the possibilities opened up by logical innovation in the fundamental areas of metaphysics resulted in his working primarily in these two, closely connected fields. It is this work in logic and metaphysics that is the main focus of what follows.     

Exploring Expressive Sandwork as a Form of Psychosocial Care: A Case Study of a Vulnerable Adolescent

This paper explores the use of expressive sandwork as a form of psychological support for a youth with psychosocial vulnerability. A case study, which emanated from a community outreach project, is briefly described of a male black participant, from a low socioeconomic background, who is currently in correctional services care. The participant engaged with sandplay over five weekly sessions, lasting approximately an hour each. The data obtained during these sessions were thematically analyzed and the findings suggest that expressive sandwork enabled this individual to become more aware of his emotional wellbeing and foster a sense of hope. Expressive sandwork offers a form of short-term psychological support in circumstances where limited or no help is available.
