Bootstrapping in a language of thought: a formal model of numerical concept learning

In acquiring number words, children exhibit a qualitative leap in which they transition from understanding a few number words, to possessing a rich system of interrelated numerical concepts. We present a computational framework for understanding this inductive leap as the consequence of statistical inference over a sufficiently powerful representational system. We provide an implemented model that is powerful enough to learn number word meanings and other related conceptual systems from naturalistic data. The model shows that bootstrapping can be made computationally and philosophically well-founded as a theory of number learning. Our approach demonstrates how learners may combine core cognitive operations to build sophisticated representations during the course of development, and how this process explains observed developmental patterns in number word learning.     

Low-effort thought promotes political conservatism

The authors test the hypothesis that low-effort thought promotes political conservatism. In Study 1, alcohol intoxication was measured among bar patrons; as blood alcohol level increased, so did political conservatism (controlling for sex, education, and political identification). In Study 2, participants under cognitive load reported more conservative attitudes than their no-load counterparts. In Study 3, time pressure increased participants' endorsement of conservative terms. In Study 4, participants considering political terms in a cursory manner endorsed conservative terms more than those asked to cogitate; an indicator of effortful thought (recognition memory) partially mediated the relationship between processing effort and conservatism. Together these data suggest that political conservatism may be a process consequence of low-effort thought; when effortful, deliberate thought is disengaged, endorsement of conservative ideology increases.     

Misapplying autonomy: why patient wishes cannot settle treatment decisions

Theoretical Medicine and Bioethics - The principle of autonomy is widely recognized to be of utmost importance in bioethics; however, we argue that this principle is often misapplied when one fails...     

The dark side of career preference: dark side traits,motives, and values

Over 2000 people completed two validated questionnaires: one measuring “dark side” personality traits and the other a measure of values and preferences that indicates the type of work that an individual would like to do and is best suited for. Dark side variables (and demographics) accounted for between 11% (science) and 46% (affiliation) variance in specific vocation related values. Factor analysis suggested three overall value/vocation factors (enterprising, traditional, and social) and three dark side variables (moving against, away from, and toward others). The three dark side factors predicted around a third of the variance in favoring enterprising and social occupations. Implications for vocational guidance and limitations of the study are considered.     

Memory for child sexual abuse information: Simulated memory error and individual differences

Building on the simulated-amnesia work of Christianson and Bylin (Applied Cognitive Psychology, 13, 495–511, 1999), the present research introduces a new paradigm for the scientific study of memory of childhood sexual abuse information. In Session 1, participants mentally took the part of an abuse victim as they read an account of the sexual assault of a 7-year-old. After reading the narrative, participants were randomly assigned to one of four experimental conditions: They (1) rehearsed the story truthfully (truth group), (2) left out the abuse details of the story (omission group), (3) lied about the abuse details to indicate that no abuse had occurred (commission group), or (4) did not recall the story during Session 1 (no-rehearsal group). One week later, participants returned for Session 2 and were asked to truthfully recall the narrative. The results indicated that, relative to truthful recall, untruthful recall or no rehearsal at Session 1 adversely affected memory performance at Session 2. However, untruthful recall resulted in better memory than did no rehearsal. Moreover, gender, PTSD symptoms, depression, adult attachment, and sexual abuse history significantly predicted memory for the childhood sexual abuse scenario. Implications for theory and application are discussed.     

Developing an Understanding of Race Talk

The aim of this paper is to give an outline of the discursive psychological literature focussing on prejudice and race talk and to show how recent findings suggest a development in this understanding. The paper begins with an outline of the discursive approach and the way in which it conceptualises race talk. Next, an overview of the ways in which people attempt to make prejudicial arguments so as to prevent them from appearing to be prejudiced, because of a norm against prejudice, is presented. It is then shown how challenges are being made to this norm against prejudice so that in some cases, prejudice can be viewed as acceptable, and in others, the taboo against prejudice is presented as being discriminatory on the grounds of preventing freedom of speech and proper debate.     

The transgenerational trauma and resilience genogram

The understanding of trauma within counseling has expanded to include the salience of ecosystemic factors and to acknowledge the importance of multicultural and social justice considerations. Transgenerational trauma and resilience offers a framework that examines trauma across generations, attends to ecosystemic concerns, and adheres to a strengths-based perspective. However, given the complexity of trauma counseling and attending to the multitude of ecosystemic factors, counselors and psychologists may struggle to conduct comprehensive assessments and interventions with their clients. Genograms have long been used to clarify complex family and psychological patterns through visual representations, and are, therefore, a promising tool to meet this need. The Transgenerational Trauma and Resilience Genogram (TTRG) was created as a dynamic tool that can assist practitioners in conducting compressive trauma assessment and intervention from a transgenerational trauma and resilience framework. The TTRG emphasizes an ecosystemic view of trauma, culturally relevant and strength-based interventions, and attention to sociopolitical concerns that may impact trauma and recovery. The author explicates the use of the TTRG in trauma counseling, including the theoretical foundations and implications for trauma and recovery. A case example of the use of the TTRG and implications for counseling practice using the TTRG and its guiding principles are provided.
