ONE TRUE LOGIC?

This is a paper about the constituents of arguments. It argues that several different kinds of truth-bearer may be taken to compose arguments, but that none of the obvious candidates—sentences, propositions, sentence/truth-value pairs etc.—make sense of logic as it is actually practiced. The paper goes on to argue that by answering the question in different ways, we can generate different logics, thus ensuring a kind of logical pluralism that is different from that of J. C. Beall and Greg Restall.     

Before escalation: behavioral and affective forecasting in escalation of commitment

This research examines preinvestment forecasting processes in escalation of commitment, considering two questions: whether individuals are able to accurately predict their behavior and affect in escalation situations and how forecasting processes may be linked to actual escalation. Three experiments demonstrated that individuals underpredicted their escalation and overpredicted their postescalation regret. Two of the experiments also indicated that the less individuals predicted being entrapped, the more they escalated. Counter to expectations, anticipated regret did not predict escalation. The discussion focuses on the theoretical and practical importance of forecasting on escalation and on the importance of understanding both behavioral and affective forecasting effects simultaneously.     

Mental health teaching to UK psychology undergraduates: report of a survey

One of the limitations on developing more progressive applied psychology training is the teaching received by students at undergraduate level. In this study, we focus on the provision of teaching about mental health or its equivalents (e.g. abnormal psychology and clinical psychology) on UK undergraduate psychology programmes. Most students who go on to train as clinical psychologists will have received teaching on modules like these. A survey questionnaire was sent to 109 university departments which might offer a module in mental health mental health module and 348 individuals who might be involved in such modules. The majority of programmes responding offered a mental health module, which was available each year as an optional subject. A number of findings on the content and delivery of the modules are reported and a number of recommendations are made including more involvement from practitioners and service users.

The ‘Flexible’ Immigrant? Human Capital Discourse, the Family Household and Labour Market Strategies

As Canadian immigration policy increasingly selects ‘flexible’ immigrants based on their human capital, it correspondingly problematises immigrant families. In drawing on interviews, conducted over a 5-year period in two different neighbourhoods in the Greater Vancouver area, we followed the paths of family households that recently immigrated to Canada. We argue that households not only provide fundamental support in the migration process, but also enable immigrants to adopt flexible strategies to deal with precarious circumstances and thereby begin the process of integration. Rather than being a ‘problem’, immigrant households, and particularly women’s support roles within them, may be a critical lynchpin to successful integration.     

Impulsiveness and resource allocation: Testing Humphreys and Revelle’s (1984) explanation of impulsive personality

Humphreys and Revelle [Humphreys, M. S., Revelle, W. (1984). Personality, motivation and performance: A theory of the relationship between individual differences and information processing. Psychological Review, 91, 153–184] suggest that impulsive individuals have relatively greater capacity to improve performance through task-directed resource allocation. This implies that there will be a differential effect of increases in effort intensity on performance for high and low impulsive individuals. Two quasi-experiments tested this prediction using a relative-judgement task (total N = 108, 68 females), however neither revealed the predicted interaction. In light of these findings, we re-consider the Humphreys–Revelle model in relation to independent but potentially related theory and research.     

Adults With Attention‐Deficit/Hyperactivity Disorder: Assessment and Treatment Strategies

Attention‐deficit/hyperactivity disorder (ADHD) among adults is characterized by inattentiveness and impulsivity. This article provides counselors with information about the etiology, assessment, and treatment of adult ADHD. The identification of the genetic and neurological features of ADHD has led to improvements in evaluation and treatment. Assessment of ADHD requires knowledge of the defining characteristics, subtypes, comorbid features, and functional aspects of ADHD. Effective treatments include both medical management and counseling to address psychosocial deficits.     

Effort during visual search and counting: insights from pupillometry

We investigated the processing effort during visual search and counting tasks using a pupil dilation measure. Search difficulty was manipulated by varying the number of distractors as well as the heterogeneity of the distractors. More difficult visual search resulted in more pupil dilation than did less difficult search. These results confirm a link between effort and increased pupil dilation. The pupil dilated more during the counting task than during target-absent search, even though the displays were identical, and the two tasks were matched for reaction time. The moment-to-moment dilation pattern during search suggests little effort in the early stages, but increasingly more effort towards response, whereas the counting task involved an increased initial effort, which was sustained throughout the trial. These patterns can be interpreted in terms of the differential memory load for item locations in each task. In an additional experiment, increasing the spatial memory requirements of the search evoked a corresponding increase in pupil dilation.These results support the view that search tasks involve some, but limited, memory for item locations, and the effort associated with this memory load increases during the trials. In contrast, counting involves a heavy locational memory component from the start.     

Opposite aftereffects for Chinese and Caucasian faces are selective for social category information and not just physical face differences

Opposite changes in perception (aftereffects) can be simultaneously induced for faces from different social categories—for example, Chinese and Caucasian faces. We investigated whether these aftereffects are generated in high-level face coding that is sensitive to the social category information in faces, or in earlier visual coding sensitive to simple physical differences between faces. We caricatured the race of face stimuli and created face continua ranging from caricatured Caucasian faces (SuperCaucasian) to caricatured Chinese faces (SuperChinese). Participants were adapted to oppositely distorted faces that were a fixed physical distance apart on the morph continua. Larger opposite aftereffects were found following adaptation to faces from different race categories (e.g., contracted Chinese and expanded Caucasian faces), than for faces that were the same physical distance apart on the morph continua, but were within a race category (e.g., contracted SuperChinese and expanded Chinese faces). These results suggest that opposite aftereffects for Chinese and Caucasian faces reflect the recalibration of face neurons tuned to high-level social category information.     

Virginal Status and Adolescent Delinquency: The Birds and the Bees,Deviance, and Teens

Much of society deems pre-marital adolescent sexual activity to be deviant. Current research seeks to determine if losing one’s virginity has an impact on participation in delinquent acts. It is hypothesized that youth who are more socially bonded to conventional people and activities, with higher levels of self-control, will not have participated in sexual intercourse and will have lower rates of delinquency. Data from Add Health are analyzed. Results do not indicate a significant effect of virginal status on delinquency. However, various social bonds were found to differentially effect delinquency for virgins and non-virgins, which may be important to consider.     

Just responses to problems associated with the brain drain: Identity,community, and obligation in an unjust world

In this essay, which forms part of a symposium on the brain drain, I respond to the arguments of several critics. I defend my proposals concerning how to address problems associated with high levels of skilled migration, especially in the face of concerns about identity, community and obligation in an unjust world.
