Universal Features In Phonological Neighbor Networks, Kevin S. Brown, Paul D. Allopenna, William R. Hunt, Rachael Steiner, Elliot Saltzman, Ken Mcrae, James S. Magnuson

Psychology Publications

Human speech perception involves transforming a countinuous acoustic signal into discrete linguistically meaningful units (phonemes) while simultaneously causing a listener to activate words that are similar to the spoken utterance and to each other. The Neighborhood Activation Model posits that phonological neighbors (two forms [words] that differ by one phoneme) compete significantly for recognition as a spoken word is heard. This definition of phonological similarity can be extended to an entire corpus of forms to produce a phonological neighbor network (PNN). We study PNNs for five languages: English, Spanish, French, Dutch, and German. Consistent with previous work, we find that …

Abstract Concepts And Pictures Of Real-World Situations Activate One Another., Ken Mcrae, Daniel Nedjadrasul, Raymond Pau, Bethany Pui-Hei Lo, Lisa King

Psychology Publications

Abstract concepts typically are defined in terms of lacking physical or perceptual referents. We argue instead that they are not devoid of perceptual information because knowledge of real-world situations is an important component of learning and using many abstract concepts. Although the relationship between perceptual information and abstract concepts is less straightforward than for concrete concepts, situation-based perceptual knowledge is part of many abstract concepts. In Experiment 1, participants made lexical decisions to abstract words that were preceded by related and unrelated pictures of situations. For example, share was preceded by a picture of two girls sharing a cob of …

Semantic Memory, Eiling Yee, Michael N. Jones, Ken Mcrae

Psychology Publications

How is it that we know what a dog and a tree are, or, for that matter, what knowledge is? Our semantic memory consists of knowledge about the world, including concepts, facts and beliefs. This knowledge is essential for recognizing entities and objects, and for making inferences and predictions about the world. In essence, our semantic knowledge determines how we understand and interact with the world around us. In this chapter, we examine semantic memory from cognitive, sensorimotor, cognitive neuroscientific, and computational perspectives. We consider the cognitive and neural processes (and biases) that allow people to learn and represent concepts, …

Evidence For A Bifactor Structure Of The Scales Of Psychological Well-Being Using Exploratory Structural Equation Modeling, Jose A. Espinoza, John P. Meyer, Brittney K. Anderson, Chelsea Vaters, Christina Politis

Psychology Publications

This research investigates the much-debated factor structure of the 54-item version of Ryff’s (1989) Scales of Psychological Well-being (SPWB). Using two samples (n₁ = 573; n₂ = 449) of undergraduate university students, we apply confirmatory factor analysis (CFA) along with recently developed exploratory structural equation modeling (ESEM) techniques to evaluate several unidimensional and multidimensional models identified in previous research, as well as a new bifactor model. In a bifactor model, items load directly on both a global and a specific factor; when tested using ESEM, cross-loadings on other specific factors are also permitted and are targeted to …

Not The Years In Your Life, But The Life In Your Years: Lessons From Canadian Psychology On Living Fully., David J.A. Dozois

Psychology Publications

Over the past couple of decades, there has been an increasing focus on positive psychology in both the popular media and the scientific literature. Prior to this time, the predominant focus has been on what is aberrant or deficient, and how to ameliorate problems or dysfunction (i.e., a psychopathology orientation). Indeed, my own research has focused on cognitive vulnerability to depression and how we can understand and modify underlying core beliefs and cognitive structures. In this article, I deviate from my own ‘comfort zone’ to highlight some key concepts related to understanding what makes life fulfilling and meaningful. Specific lessons …

Cognitive Change In Cognitive-Behavioural Therapy V. Pharmacotherapy For Adult Depression: A Longitudinal Mediation Analysis, Leanne Quigley, David J.A. Dozois, R. Michael Bagby, Daniela S S Lobo, Lakshmi Ravindran, Lena C Quilty

Psychology Publications

Background Although cognitive-behavioural therapy (CBT) is a well-established treatment for adult depression, its efficacy and efficiency may be enhanced by better understanding its mechanism(s) of action. According to the theoretical model of CBT, symptom improvement occurs via reductions in maladaptive cognition. However, previous research has not established clear evidence for this cognitive mediation model.

Methods The present study investigated the cognitive mediation model of CBT in the context of a randomized controlled trial of CBT v. antidepressant medication (ADM) for adult depression. Participants with major depressive disorder were randomized to receive 16 weeks of CBT (n = 54) or ADM …
