On a medieval solution to the liar paradox

In this paper, I examine a solution to the Liar paradox found in the work of Ockham, Burley, and Pseudo-Sherwood. I reject the accounts of this solution offered by modern commentators. I argue that this medieval line suggests a non-hierarchical solution to the Liar, according to which ‘true’ is analysed as an indexical term, and paradox is avoided by minimal restrictions on tokens of ‘true’. In certain respects, this solution resembles the recent approaches of Charles Parsons and Tyler Burge; in other respects, it is related to a suggestion of Gödel. But, as a whole, it suggests an original solution to the Liar paradox, quite unlike any current proposals.     

How Does Self-Complexity of Identity Moderate the Relationship between Strain and Crime?

Studies are inconclusive as to which characteristics exacerbate or inhibit criminal reactions to strain. This study examines how self-complexity of identity conditions the relationship between strain and crime. Those who are lower in self-complexity, or those with few overlapping identities, should be more likely to respond to strain with crime than those who are higher in self-complexity. This proposition was tested through analyzing a cross-sectional survey of 357 undergraduates at a Southeastern university. Strong support was found for the conditioning effect of self-complexity on serious crime while partial support was found for this effect on property crime.     

An application of protection motivation theory to riskier single-occasion drinking

Abstract

Cognitions in relation to drinking alcohol on a single occasion were explored within the framework of Protection Motivation Theory (PMT). One hundred and twenty three students provided information about their current weekend drinking, beliefs about drinking, and intentions to drink at safer limits. Data on self reported weekend drinking were gathered two weeks later from the same respondents. Analyses showed PMT components to be predictive of intentions but not of later behaviour. Perceived severity and self-efficacy related significantly to intentions for drinking at safer limits. No PMT measure differentiated between those who engaged in riskier single-occasion drinking at follow up and those whose drinking was less risky. Past behaviour was the only significant predictor of riskier single-occasion drinking at follow up. Implications for the current utility of PMT are discussed particularly in relation to respondents' reactions to newly identified health threats.     

Social Problem-Solving Skills in Children with Traumatic Brain Injury: Long-Term Outcomes and Prediction of Social Competence

The effects of childhood traumatic brain injury (TBI) on social problem-solving were examined in 35 children with severe TBI, 40 children with moderate TBI, and 46 children with orthopedic injuries (OI). The children were recruited prospectively following injuries that occurred between 6 and 12 years of age. They were followed longitudinally, and ranged from 9 to 18 years of age at the time of the current study, which occurred on average 4 years post injury. They were administered a semi-structured interview used in previous research on social problem-solving to assess the developmental level of their responses to hypothetical dilemmas involving social conflict. Children in the severe TBI group defined the social dilemmas and generated alternative strategies to solve those dilemmas at the same developmental level as did children in the OI group. However, they articulated lower-level strategies as the best way to solve the dilemmas and used lower-level reasoning to evaluate the effectiveness of the strategies. After controlling for group membership, race, socioeconomic status, IQ, and age, children's social problem-solving, and particularly the developmental level of their preferred strategies for resolving conflicts, predicted parents ratings of children's social skills, peer relationships, aggressive behavior, and academic performance. The findings indicate that children with severe TBI demonstrate selective, long-term deficits in their social problem-solving skills that may help to account for their poor social and academic outcomes.     

Introduction: Using Techniques via the Therapeutic Relationship

In this work, we have the opportunity to hear people’s most private concerns, worries, distress, and share in their hopes, aspirations, and dreams for the future. The work involved in the practice of cognitive behavior therapy; our knowledge, theories, techniques, and strategies are practically useless if we are unable to relate to our clients. Relational attributes were incorporated as part of the defining features essential to therapeutic change in the seminal guide for cognitive therapy (A. T. Beck, Rush, Shaw, & Emery, 1979). Conceptualizations of “collaboration” and “empiricism” have since been misconstrued with the construct of the working alliance in the past, although both have unique distinctions and implications for practice. This article presents an introduction to a special series in Cognitive and Behavioral Practice, which illustrates the vital role of collaborative empiricism within culturally responsive CBT, through the structure of the therapy session, cognitive case conceptualization, self-monitoring, interventions focused on cognitive change, and exposure to emotions and situations. We invite you to join with us in considering the extent to which the ideas shared herein are relevant for your work with clients. It is also our hope that you will consider evaluating and incorporating the utility of these ideas in your therapy.     

Frequency and predictability effects in eye fixations for skilled and less-skilled deaf readers

The illiteracy rate in the deaf population has been alarmingly high for several decades, despite the fact that deaf children go through the standard stages of schooling. Much research addressing this issue has focused on word-level processes, but in the recent years, little research has focused on sentence-levels processes. Previous research (Fischler, 1985) investigated word integration within context in college-level deaf and hearing readers in a lexical decision task following incomplete sentences with targets that were congruous or incongruous relative to the preceding context; it was found that deaf readers, as a group, were more dependent on contextual information than their hearing counterparts. The present experiment extended Fischler's results and investigated the relationship between frequency, predictability, and reading skill in skilled hearing, skilled deaf, and less-skilled deaf readers. Results suggest that only less-skilled deaf readers, and not all deaf readers, rely more on contextual cues to boost word processing. Additionally, early effects of frequency and predictability were found for all three groups of readers, without any evidence for an interaction between frequency and predictability.     

Us versus them: Understanding the process of race perception with event-related brain potentials

Race is powerful social signal, imbued with a great deal of meaning and capable of affecting a wide range of behaviours and judgements. This review focuses on the use of event-related brain potentials (ERPs) to better understand the process and implications of race perception. Research to date repeatedly demonstrates the speed and automaticity with which racial category membership is encoded. The quick and relatively obligatory encoding of racial ingroup and outgroup distinctions in turn affects a variety of subsequent racially biased behaviours. Such findings not only speak to the close link between social categorization and behaviour, but also have been used to understand how the effects of race perception can be moderated.     

Unsegmented text delays word identification: Evidence from a survival analysis of fixation durations

The present study employed distributional analyses of fixation times to examine the impact of removing spaces between words during reading. Specifically, we presented high and low frequency target words in a normal text condition that contained spaces (e.g., “John decided to sell the table in the garage sale”) and in an unsegmented text condition that contained random numbers instead of spaces (e.g., “John4decided8to5sell9the7table2in3the9garage6sale”). The unsegmented text condition produced larger word frequency effects relative to the normal text condition for the gaze duration and total time measures (for similar findings, see Rayner, Fischer, & Pollatsek, 1998), which indicates that removing spaces can impact the word identification stage of reading. To further examine the effect of spacing on word identification, we used distributional analyses of first-fixation durations to contrast the time course of word frequency effects in the normal versus the unsegmented text conditions. In replication of prior findings (Reingold, Reichle, Glaholt, & Sheridan, 2012; Staub, White, Drieghe, Hollway, & Rayner, 2010), ex-Gaussian fitting revealed that the word frequency variable impacted both the shift and the skew of the distributions, and this pattern of results occurred for both the normal and unsegmented text conditions. In addition, a survival analysis technique revealed a later time course of word frequency effects in the unsegmented relative to the normal condition, such that the earliest discernible influence of word frequency was 112 ms from the start of fixation in the normal text condition, and 152 ms in the unsegmented text condition. This delay in the temporal onset of word frequency effects in the unsegmented text condition strongly suggests that removing spaces delays the word identification stage of reading. Possible underlying mechanisms are discussed, including lateral masking and word segmentation.     

Encoding the target or the plausible preview word? The nature of the plausibility preview benefit in reading Chinese

Previous studies have shown that a plausible preview word can facilitate the processing of a target word as compared to an implausible preview word (a plausibility preview benefit effect) when reading Chinese (Yang, Wang, Tong, & Rayner, 2012; Yang, 2013). Regarding the nature of this effect, it is possible that readers processed the meaning of the plausible preview word and did not actually encode the target word (given that the parafoveal preview word lies close to the fovea). The current experiment examined this possibility with three conditions wherein readers received a preview of a target word that was either (1) identical to the target word (identical preview), (2) a plausible continuation of the pre-target text, but the post-target text in the sentence was incompatible with it (initially plausible preview), or (3) not a plausible continuation of the pre-target text, nor compatible with the post-target text (implausible preview). Gaze durations on target words were longer in the initially plausible condition than the identical condition. Overall, the results showed a typical preview benefit, but also implied that readers did not encode the initially plausible preview. Also, a plausibility preview benefit was replicated: gaze durations were longer with implausible previews than the initially plausible ones. Furthermore, late eye movement measures did not reveal differences between the initially plausible and the implausible preview conditions, which argues against the possibility of misreading the plausible preview word as the target word. In sum, these results suggest that a plausible preview word provides benefit in processing the target word as compared to an implausible preview word, and this benefit is only present in early but not late eye movement measures.
