Consequences Of Repeated Ethanol Exposure During Early Or Late Adolescence On Conditioned Taste Aversions In Rats, Jessica Saalfield, Linda Spear Dec 2015

Consequences Of Repeated Ethanol Exposure During Early Or Late Adolescence On Conditioned Taste Aversions In Rats, Jessica Saalfield, Linda Spear

Psychology Faculty Scholarship

Alcohol use is prevalent during adolescence, yet little is known about possible long-lasting consequences. Recent evidence suggests that adolescents are less sensitive than adults to ethanol's aversive effects, an insensitivity that may be retained into adulthood after repeated adolescent ethanol exposure. This study assessed whether intermittent ethanol exposure during early or late adolescence (early-AIE or late-AIE, respectively) would affect ethanol conditioned taste aversions 2 days (CTA1) and >3 weeks (CTA2) post-exposure using supersaccharin and saline as conditioning stimuli (CS), respectively. Pair-housed male Sprague-Dawley rats received 4 g/kg i.g. ethanol (25%) or water every 48 h from postnatal day (P) 25-45 …


One Giant Leap For Categorizers: One Small Step For Categorization Theory, David J. Smith, Shawn W. Ell Sep 2015

One Giant Leap For Categorizers: One Small Step For Categorization Theory, David J. Smith, Shawn W. Ell

Psychology Faculty Scholarship

We explore humans’ rule-based category learning using analytic approaches that highlight their psychological transitions during learning. These approaches confirm that humans show qualitatively sudden psychological transitions during rule learning. These transitions contribute to the theoretical literature contrasting single vs. multiple category-learning systems, because they seem to reveal a distinctive learning process of explicit rule discovery. A complete psychology of categorization must describe this learning process, too. Yet extensive formal-modeling analyses confirm that a wide range of current (gradient-descent) models cannot reproduce these transitions, including influential rule-based models (e.g., COVIS) and exemplar models (e.g., ALCOVE). It is an important theoretical conclusion …


Fifty Psychological And Psychiatric Terms To Avoid: A List Of Inaccurate, Misleading, Misused, Ambiguous, And Logically Confused Words And Phrases, Scott O. Lilienfeld, Katheryn C. Sauvigne, Steven J. Lynn, Robin L. Cautin, Robert D. Latzman, Irwin D. Waldman Aug 2015

Fifty Psychological And Psychiatric Terms To Avoid: A List Of Inaccurate, Misleading, Misused, Ambiguous, And Logically Confused Words And Phrases, Scott O. Lilienfeld, Katheryn C. Sauvigne, Steven J. Lynn, Robin L. Cautin, Robert D. Latzman, Irwin D. Waldman

Psychology Faculty Scholarship

The goal of this article is to promote clear thinking and clear writing among students and teachers of psychological science by curbing terminological misinformation and confusion. To this end, we present a provisional list of 50 commonly used terms in psychology, psychiatry, and allied fields that should be avoided, or at most used sparingly and with explicit caveats. We provide corrective information for students, instructors, and researchers regarding these terms, which we organize for expository purposes into five categories: inaccurate or misleading terms, frequently misused terms, ambiguous terms, oxymorons, and pleonasms. For each term, we (a) explain why it is …


Do Semantic Contextual Cues Facilitate Transfer Learning From Video In Toddlers?, Laura Zimmermann, Alecia Moser, Amanda Grenell, Kelly Dickerson, Qianwen Yao, Peter Gerhardstein, Rachel Barr May 2015

Do Semantic Contextual Cues Facilitate Transfer Learning From Video In Toddlers?, Laura Zimmermann, Alecia Moser, Amanda Grenell, Kelly Dickerson, Qianwen Yao, Peter Gerhardstein, Rachel Barr

Psychology Faculty Scholarship

Young children typically demonstrate a transfer deficit, learning less from video than live presentations. Semantically meaningful context has been demonstrated to enhance learning in young children. We examined the effect of a semantically meaningful context on toddlers' imitation performance. Two- and 2.5-year-olds participated in a puzzle imitation task to examine learning from either a live or televised model. The model demonstrated how to assemble a three-piece puzzle to make a fish or a boat, with the puzzle demonstration occurring against a semantically meaningful background context (ocean) or a yellow background (no context). Participants in the video condition performed significantly worse …


Imagining The Impossible Before Breakfast: The Relation Between Creativity, Dissociation, And Sleep, Dalena Van Heugten-Van Der Kloet, Jan Cosgrave, Harald Merckelbach, Ross Haines, Stuart Golodetz, Steven J. Lynn Mar 2015

Imagining The Impossible Before Breakfast: The Relation Between Creativity, Dissociation, And Sleep, Dalena Van Heugten-Van Der Kloet, Jan Cosgrave, Harald Merckelbach, Ross Haines, Stuart Golodetz, Steven J. Lynn

Dissociative symptoms have been related to higher rapid eye movement sleep density, a sleep phase during which hyperassociativity may occur. This may enhance artistic creativity during the day. To test this hypothesis, we conducted a creative photo contest to explore the relation between dissociation, sleep, and creativity. During the contest, participants (N = 72) took one photo per day for five consecutive days, based on specific daily themes (consisting of single words) and the instruction to take as creative a photo as possible each day. Furthermore, they completed daily measures of state dissociation and a short sleep diary The photos …


Sleeve Gastrectomy And Roux-En-Y Gastric Bypass Alter The Gut-Brain Communication, Lindsey Ballsmider, Alexandra Vaughn, Michelle David, Andras Hajnal, Patricia Di Lorenzo, Krzysztof Czaja Jan 2015

Sleeve Gastrectomy And Roux-En-Y Gastric Bypass Alter The Gut-Brain Communication, Lindsey Ballsmider, Alexandra Vaughn, Michelle David, Andras Hajnal, Patricia Di Lorenzo, Krzysztof Czaja

Psychology Faculty Scholarship

This study investigated the anatomical integrity of vagal innervation of the gastrointestinal tract following vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) operations. The retrograde tracer fast blue (FB) was injected into the stomach to label vagal neurons originating from nodose ganglion (NG) and dorsal motor nucleus of the vagus (DMV). Microglia activation was determined by quantifying changes in the fluorescent staining of hindbrain sections against an ionizing calcium adapter binding molecule 1 (Iba1). Reorganization of vagal afferents in the hindbrain was studied by fluorescent staining against isolectin 4 (IB4). The density of Iba1-and IB4-immunoreactivity was analyzed using Nikon …


Excusing Murder? Conservative Jurors’ Acceptance Of The Gay Panic Defense, Cynthia J. Najdowski, Jessica Salerno, Bette L. Bottoms, B. L. Harrington, Dave Kemner Jan 2015

Excusing Murder? Conservative Jurors’ Acceptance Of The Gay Panic Defense, Cynthia J. Najdowski, Jessica Salerno, Bette L. Bottoms, B. L. Harrington, Dave Kemner

Psychology Faculty Scholarship

We conducted a simulated trial study to investigate the effectiveness of a “gay-panic” provocation defense as a function of jurors’ political orientation. Mock jurors read about a murder case in which a male defendant claimed a victim provoked the killing by starting a fight, which either included or did not include the male victim making an unwanted sexual advance that triggered a state of panic in the defendant. Conservative jurors were significantly less punitive when the defendant claimed to have acted out of gay panic as compared to when this element was not part of the defense. In contrast, liberal …


Stereotype Threat And Racial Differences In Citizens’ Experiences Of Police Encounters, Cynthia J. Najdowski, Bette L. Bottoms, Phillip Atiba Goff Jan 2015

Stereotype Threat And Racial Differences In Citizens’ Experiences Of Police Encounters, Cynthia J. Najdowski, Bette L. Bottoms, Phillip Atiba Goff

Psychology Faculty Scholarship

We conducted 2 studies to investigate how cultural stereotypes that depict Blacks as criminals affect the way Blacks experience encounters with police officers, expecting that such encounters induce Blacks to feel stereotype threat (i.e., concern about being judged and treated unfairly by police because of the stereotype). In Study 1, we asked Black and White participants to report how they feel when interacting with police officers in general. As predicted, Blacks, but not Whites, reported concern that police officers stereotype them as criminals simply because of their race. In addition, this effect was found for Black men but not Black …


The Potential Impact Of Rape Culture On Juror Decision Making: Implications For Wrongful Acquittals In Sexual Assault Trials., Meagen M. Hildebrand, Cynthia J. Najdowski Jan 2015

The Potential Impact Of Rape Culture On Juror Decision Making: Implications For Wrongful Acquittals In Sexual Assault Trials., Meagen M. Hildebrand, Cynthia J. Najdowski

Psychology Faculty Scholarship

Feminist writers contend that Americans live in a culture that supports sexualized aggression and violence against women. This “rape culture” is reflected in our society by the pervasive endorsement of rape myths and sexual objectification of women, both of which are legitimized by everyday media. One potential consequence of living in a rape culture is that individuals may themselves come to endorse rape myths and sexually objectify women, and, in turn, perceive certain forms of sexual violence against women as defensible. This is concerning considering the significant role that laypeople play in administering justice in sexual assault cases, but research …


The Influence Of A Juvenile's Abuse History On Support For Sex Offender Registration, Cynthia J. Najdowski, M. C. Stevenson, J. M. Salerno, T. R. A. Wiley, B. L. Bottoms, K. M. Farnum Jan 2015

The Influence Of A Juvenile's Abuse History On Support For Sex Offender Registration, Cynthia J. Najdowski, M. C. Stevenson, J. M. Salerno, T. R. A. Wiley, B. L. Bottoms, K. M. Farnum

Psychology Faculty Scholarship

We investigated whether and how a juvenile’s history of experiencing sexual abuse affects public perceptions of juvenile sex offenders in a series of 5 studies. When asked about juvenile sex offenders in an abstract manner (Studies 1 and 2), the more participants (community members and undergraduates) believed that a history of being sexually abused as a child causes later sexually abusive behavior, the less likely they were to support sex offender registration for juveniles. Yet when participants considered specific sexual offenses, a juvenile’s history of sexual abuse was not considered to be a mitigating factor. This was true when participants …

The field of psychology and law, including forensic psychology, is an exciting concentration of research activity and student training and has grown rapidly, but to what extent have teaching and training efforts in the field been systematically catalogued and evaluated? We conducted a historical review and content analysis of the American and Canadian literature on the scholarship of teaching and training in the field. This review catalogs (a) information related to the development of training and teaching, (b) descriptions of programs and courses at various levels, and (c) articles on teaching resources or techniques in this field. We hope it …
