Is synaesthesia one condition or many? A large-scale analysis reveals subgroups

Synaesthesia is a broadly defined neural phenomenon in which stimulation of a sense or concept triggers a second perception not normally associated with the stimulus. For example, letters or numbers may trigger a colour experience, sounds may trigger a taste sensation, or tastes may trigger a feeling of touch. Dozens of forms of synaesthesia have been reported, but the relationship between the different forms has not been studied: is someone with a particular form of synaesthesia likely to possess other types? If so, which ones? As an inroad to illuminating underlying mechanisms, we here examine which different synaesthesia types tend to co-occur. We analyzed reports of the forms of synaesthesia experienced by 19,133 participants who completed the Synaesthesia Battery (Eagleman, Kagan, Nelson, Sagaram, & Sarma, 2007), using correlation analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and multidimensional scaling (MDS). Our analyses converged on the finding of five distinct groupings of synaesthesia forms. We label these coloured sequence synaesthesias (CSSs), coloured music synaesthesias, non-visual sequela synaesthesias, spatial sequence synaesthesia (SSS), and coloured sensation synaesthesias. Collectively, our findings reveal that synaesthesia is an umbrella term that encompasses several distinct groups with independent probabilities of expression, and this may in turn suggest distinct underlying mechanisms and the possibility of different genetic bases.     

The Seattle longitudinal study: relationship between personality and cognition

This article reviews the history, measures and principal findings of the Seattle Longitudinal Study. This study began in 1956 focusing upon age differences and age changes in cognitive abilities. Its sampling frame is a large HMO in the Pacific Northwest. The study has been expanded to investigate various influences on cognitive aging including, cognitive styles, personality traits, life styles, and family environment. Current interest is also in the early detection of risk for dementia. In addition, this article reports original analyses of the relation of personality dimensions to cognitive abilities (both concurrent and longitudinal). While personality remains relatively stable over the adult life span, modest proportions of variance are shared between various personality traits and the cognitive abilities.     

Competence in everyday activities as a predictor of cognitive risk and mortality

This study examined the association of a performance-based measure of everyday functioning with clinically meaningful outcomes. Elderly participants in a prospective study of dementia were assessed at two occasions on the Everyday Problems Test for Cognitively Challenged Elderly (EPCCE), a performance-based measure of everyday functioning. Older adults who remained cognitively intact performed approximately 0.66 SD units higher on the EPCCE at both occasions than elders rated as impaired, when covarying on age, education, gender, and cognitive status. Relative to the nonimpaired participants, decline in EPCCE performance over a 2-year interval was significantly greater for impaired participants and those participants who transitioned from nonimpaired to impaired over the course of the study. Increased risk of mortality was associated with lower baseline scores and decline in EPCCE performance even after controlling for demographic variables and performance on the Mini-Mental State Examination. Given the clinical importance of identifying "at risk" elders for impairment, the findings from this study provide initial evidence for the predictive utility of performance-based measures of everyday functioning.     

Rehearsal and retrieval processes in free recall of categorized lists

The relationships between rehearsal and subsequent retrieval characteristics were examined in the context of free recall of categorized lists. The results indicated a direct correspondence between the frequency of rehearsal and the order and speed of retrieval within categories. The same relationship obtained for the categories themselves. It was suggested that both retrieval time and order effects can be predicted in terms of the organization of input processing and the resultant repetition frequency of categories and exemplars.     

Application of Problem Solving Therapy for Late-Life Anxiety

Cognitive behavioral therapy for anxiety has demonstrated lower efficacy in older compared with younger adults. Yet, few other evidence-based options for late-life anxiety have been examined. This case series aimed to demonstrate the application of Problem Solving Therapy (PST) to older adults with anxiety disorders building on PST’s strong empirical support for treating late-life depression. PST was implemented to treat three older primary-care patients diagnosed with anxiety disorders. We present treatment outcomes and discuss the feasibility and acceptability of using PST to treat these patients. Implications and lessons learned from these patients are discussed to inform further development of PST to better meet the needs of older patients suffering from late-life anxiety.     

Strategy Use in Reasoning Training With Older Adults

The relationship between strategy use and cognitive training gains on reasoning ability is examined in a sample of 393 older participants in the Seattle Longitudinal Training Study. Pre- and posttest gains on the use of strategies specific to reasoning ability were compared for the elderly trained on reasoning versus spatial orientation ability. The present study involves an objective behavioral method of measuring strategy use on tests of inductive reasoning. Results showed that participants trained on reasoning significantly increased strategy use from pre- to posttest on two reasoning outcome measures compared to participants trained on spatial orientation. Higher strategy use by inductive reasoning trainees was also associated with greater training gain on reasoning outcome measures, suggesting strategy use as a possible mechanism of training gain. In addition, young–old participants and those with higher education, irrespective of training condition, exhibited greater pre- to posttest gain in strategy use.     

Latent self-oriented and socially prescribed perfectionism: Tests of factorial,convergent, and discriminant validity using self- and informant reports

Using latent variables for self-oriented perfectionism (i.e., demanding perfection of oneself) and socially prescribed perfectionism (i.e., perceiving others are demanding perfection of oneself) has advantages. However, few studies have specifically examined the psychometric properties of these latent variables. The present study addresses this shortcoming by testing the factorial, convergent, and discriminant validity of self-oriented and socially prescribed perfectionism latent variables using self- and informant reports. It was hypothesized that (a) the factor structure of the self-oriented and socially prescribed perfectionism latent variables would be supported, (b) self- and informant reports would moderately converge, and (c) the self-oriented and socially prescribed perfectionism latent variables would be discriminable. A sample of 242 undergraduate women and 378 informants (218 mothers, 160 fathers) was recruited. Undergraduate women completed self-reports, and mothers and fathers completed informant reports. Results were consistent with hypotheses, thereby supporting (a) the factorial validity of the self-oriented and socially prescribed latent variables using self- and informant reports, (b) the convergent validity of the self-oriented and socially prescribed latent variables via moderately to strongly correlated self- and informant reports, and (c) the discriminant validity of the self-oriented and socially prescribed perfectionism latent variables. Findings suggest research using these latent variables is warranted.     

Perfectionistic self-presentation in children and adolescents: development and validation of the Perfectionistic Self-Presentation Scale--Junior Form

Research on adults indicates that perfectionistic self-presentation, the interpersonal expression of one's perfection, is associated with a variety of psychopathological outcomes independent of trait perfectionism and Big Five traits. The current article reports on the development and evidence for the validity of the subtest score interpretations of an 18-item self-report measure of perfectionistic self-presentation for children and adolescents. Analyses conducted on data from two clinical samples and one nonclinical sample of children and adolescents found that the Perfectionistic Self-Presentation Scale--Junior Form (PSPS-Jr) reflected a multidimensional model of perfectionistic self-presentation with three subscales: Perfectionistic Self Promotion, Nondisplay of Imperfection, and Nondisclosure of Imperfection. The subscale scores were found to demonstrate internal consistency, and there was good evidence supporting the validity of the interpretation of subscale scores based on this new measure. The subscales were associated with maladaptive outcomes, but were not influenced unduly by biases that included social desirability and differential item functioning by gender. Overall, the PSPS-Jr appears to be a useful measure of the expression of perfection among youths and an important tool in attempting to understand the nature and the consequences of perfectionistic self-presentation in children and adolescents.     

Confirming the Factor Structure of Attention Deficit Hyperactivity Disorder Symptoms in Adult, Nonclinical Samples

Three separate models have been proposed to describe the factor structure of attention deficit hyperactivity disorder (ADHD) in the past 20 years. The Diagnostic and Statistical Manual of Mental Disorders-III (DSM-III, 1980) proposed 3 separate factors of inattention, hyperactivity, and impulsivity. The DSM-III-R (1987) proposed a single factor. The DSM-IV (1994) described the disorder as having 2 factors: hyperactivity/impulsivity and inattention. The following 2 studies employed confirmatory factor analysis to compare each of these models and 3 alternative models. University students completed questionnaires that assessed each of the 18 symptoms listed in the DSM-IV for ADHD. The 3-factor model fit the data significantly better than each of the other models in both studies. These findings suggest that a 3-factor model of inattention, hyperactivity, and impulsivity describes adult ADHD symptoms better than current alternatives.     

Multiple channel exposure therapy for women with PTSD and comorbid panic attacks

Multiple channel exposure therapy (M-CET; Falsetti & Resnick, 2000) was developed to treat posttraumatic stress disorder (PTSD) with comorbid panic attacks and can be administered in a group format. In addition to being a cost-effective way to provide treatment, group treatment for those with PTSD has been proposed as potentially very beneficial for addressing feelings of shame related to the traumatic event as well as social isolation in general (Foy et al., 2000). Previous studies of M-CET indicate that it may be effective for the treatment of PTSD with comorbid panic attacks (Falsetti et al., 2001, 2003, 2005). The authors examine the relationship of PTSD and panic symptoms pre- and posttreatment and present 6-month follow-up data on the long-term effectiveness of M-CET.
