Grammatical gender in the production of single words: some evidence from Greek

The present study investigated the effect of prior grammatical gender information provided by the production of a bare noun on the production of a syntactically unrelated, gender-inflected color adjective. The target language was Greek. A lexical priming task involving picture naming was employed. Participants saw a series of pictures, some in color and some in black-and-white; they had to name a black-and-white picture with the single noun (prime) and a color picture with the appropriately inflected color adjective (target). Prior gender information was shown to affect subsequent production of gender-marked words. The effect was restricted to nouns of one gender class (masculine) only. The implications of these results for the representation and processing of gender in production are discussed.     

A medication screening tool for cognitive aging researchers

A Web-based medication screening tool that provides researchers with information about side effects associated with medications commonly used by older participants is described. This tool can be used for research purposes to better separate the effects of normal, healthy aging processes from the deleterious effects often associated with medication usage. Researchers can use this tool, called SMART (Screening Medications: Aging Research Taxonomy), to (a) obtain information pertaining to the cognitive, sensory, and motor side effects associated with specific medications and (b) screen medications in their research for side effect severity. The Web address for the tool is www.psychology.gatech.edu/SMART     

Neuropsychological Functioning in Chronic Lyme Disease

Lyme disease is currently the most common vector-borne illness in the United States. The disease is multisystemic, and chronic disease, in particular, may be associated with neuropsychological deficits. However, to date, only a few empirical studies exist, which examine the neuropsychological sequelae associated with chronic Lyme disease. A review of the literature shows that the deficits observed in adults with chronic Lyme disease are generally consistent with the deficits that can be seen in processes with primarily frontal systems involvement. These observations are generally consistent with neuroradiologic findings. The clinical presentation in chronic Lyme disease and the nature of the neuropsychological deficits are discussed, as are several central issues in understanding neuropsychological functioning in chronic Lyme disease, such as the impact of chronic illness, response to treatment, and the relationship between neuropsychological performance and depression, fatigue, and neurological indicators of disease.     

Generalizing treatment effects of functional family therapy: Three replications

Abstract

Functional Family Therapy with status delinquents has undergone careful scrutiny in well designed studies that included random assignment, realistic comparison treatment programs, formally trained therapists, and reasonable follow-up periods. The current report describes three replications in which FFT has been extended to new populations, has utilized less formally trained therapists, and has been applied in new treatment contexts. Taken together the replications provide important support for the generalizability of FFT across client and therapist populations.     

Think3d!: Training Spatial Thinking Fundamental to STEM Education

This article describes the initial implementation of an innovative program for elementary-age children involving origami and pop-up paper engineering to promote visuospatial thinking. While spatial ability measures correlate with science, technology, engineering, and math (STEM) success, a focus on spatial thinking is all but missing in elementary school education. Fourth-grade students took part in the program and then completed spatial thinking assessments or completed the assessments prior to program participation. All students completed assessments at three points in time—before, during, and after the intervention. Results suggest the program's promise in promoting spatial thinking, showing both spatial thinking gains and extensive engagement in the program. Questionnaire responses suggest the program may have particular appeal for girls, which could play a role in reducing gender disparities in spatial reasoning and in situations where spatial thinking can be applied.     

Decomposing the within-person and between-person sources of variation in physical activity-cognition associations for low-active older adults

Abstract

Objectives: To examine within-person and between-person sources of variation in the relationship between physical activity and cognition in older adults participating in a walking program. To explore whether demographic, health and fitness variables, and their interactions with activity, are significant predictors of cognition.

Design: Brief longitudinal burst design.

Participants: 118 participants (91 females, mean age?=?72.81?+ 5.24 years).

Main Outcome Measures: Cognition, self-reported moderate-to-vigorous walking and self-reported moderate-to-vigorous physical activity were assessed at baseline and 6, 9, 12 and 16 weeks follow-up. Attendance at weekly walks was also recorded.

Results: Within-persons, changes in physical activity were related to select measures of executive functioning, with increased activity predictive of better cognition (three of four cognitive functions, p<.05). Between-persons, activity was also associated with cognition (two of four cognitive functions, p<.05). Younger age and higher education were related to better cognition. Interactions of demographic, health, and fitness variables with changes in within-person activity were generally non-significant.

Conclusion: The results highlight the importance of distinguishing within- from between-person effects in longitudinal analyses of the association between physical activity and cognition. This stringent within-person test of association underscores the potential value of simple physical activity interventions for improving cognitive function.     

The Relationship of Suicidal Ideation to Objective and Subjective Executive Functioning

Prior research on executive ability and suicidal ideation (SI) has frequently failed to account for either symptom or performance validity. Similarly, studies have not adequately examined both objective performance on executive tests and subjective report of executive deficits in relationship to SI. The purpose of this study was to address these gaps in research by accounting for performance validity, symptom validity, and considering self-reported executive complaints with objective performance. We hypothesized that (a) increases in self-reported SI on the Personality Assessment Inventory (PAI; Morey, 1991 Morey, L. C. (1991). Personality Assessment Inventory: Professional manual. Tampa, FL: Psychological Assessment Resources. [Google Scholar]) Suicidal Ideation subscale would be related to poorer performance on objective and subjective tests of executive function and (b) level of self-reported depressive symptoms would moderate the relationship between SI and measures of executive function, such that individuals with higher levels of both depressive symptoms and executive dysfunction would be more likely to experience higher levels of SI. No measure of executive function was related to SI when accounting for demographic variables and depressive symptoms. Wisconsin Card Sort Test categories completed was the only measure of executive function to interact significantly with depressive symptoms to predict SI (β = .43). Of particular note, self-reported executive dysfunction was highly correlated with Beck Depression Inventory?II ( Beck, Steer, &; Brown, 1996 Beck, A. T., Steer, R. A., &; Brown, G. K. (1996). Beck Depression Inventory (2nd ed.). San Antonio, TX: The Psychological Corporation. [Google Scholar]) scores (r = .78). Clinical implications and future directions for research are discussed.     

The Relationship of Adverse Childhood Experiences to PTSD,Depression, Poly-Drug Use and Suicide Attempt in Reservation-Based Native American Adolescents and Young Adults

Adverse childhood experiences (ACEs) are associated with numerous risk behaviors and mental health outcomes among youth. This study examines the relationship between the number of types of exposures to ACEs and risk behaviors and mental health outcomes among reservation‐based Native Americans. In 2011, data were collected from Native American (N = 288; 15–24 years of age) tribal members from a remote plains reservation using an anonymous web‐based questionnaire. We analyzed the relationship between six ACEs, emotional, physical, and sexual abuse, physical and emotional neglect, witness to intimate partner violence, for those <18 years, and included historical loss associated symptoms, and perceived discrimination for those <19 years; and four risk behavior/mental health outcomes: post‐traumatic stress disorder (PTSD) symptoms, depression symptoms, poly‐drug use, and suicide attempt. Seventy‐eight percent of the sample reported at least one ACE and 40 % reported at least two. The cumulative impact of the ACEs were significant (p < .001) for the four outcomes with each additional ACE increasing the odds of suicide attempt (37 %), poly‐drug use (51 %), PTSD symptoms (55 %), and depression symptoms (57 %). To address these findings culturally appropriate childhood and adolescent interventions for reservation‐based populations must be developed, tested and evaluated longitudinally.     

Linking Crimes Using Behavioural Clues: Current Levels of Linking Accuracy and Strategies for Moving Forward

The number of published studies examining crime linkage analysis has grown rapidly over the last decade, to the point where a special issue of this journal has recently been dedicated to the topic. Many of these studies have used a particular measure (the area under the receiver operating characteristic curve, or the AUC) to quantify the degree to which it is possible to link crimes. This article reviews studies that have utilised the AUC and examines how good we are currently at linking crimes (within the context of these research studies) and what factors impact linking accuracy. The results of the review suggest that, in the majority of cases, moderate levels of linking accuracy are achieved. Of the various factors that have been examined that might impact linking accuracy, the three factors that appear to have the most significant impact are crime type, behavioural domain, and jurisdiction. We discuss how generalisable these results are to naturalistic investigative settings. We also highlight some of the important limitations of the linking studies that we reviewed and offer up some strategies for moving this area of research forward.
