Algebra and the adolescent brain

New fMRI evidence suggests that adolescents could be at an advantage for learning algebra compared with adults. Qin and colleagues present findings indicating that after several days of practice adolescents rely on prefrontal regions to support the retrieval of algebraic rules to solve equations, as do adults. Unlike adults, however, after practice adolescents decrease their reliance on parietal regions, which assist in the transformation of the equations, suggesting an enhanced ability for learning algebra. These findings are discussed with regard to adolescent brain maturation.     

Alexithymia--state or trait?

Alexithymia refers to a specific disturbance in emotional processing that is manifested by difficulties in identifying and verbalizing feelings and a tendency to focus on and amplify the somatic sensations that accompany emotional arousal. Alexithymia is conceptualized both as an affect-deficit disorder and a continuous personality variable. The main purpose of the present study was to investigate the stability levels of alexithymia with regard to changes in emotional distress levels caused by university exams. We tested 20 university students at four different times, before and after the exams. Alexithymic features and self-reported emotional distress (trait anxiety and physical symptoms) were measured. Whereas emotional distress measures changed significantly during the diverse phases, the level of alexithymia remained unchanged. We therefore conclude that alexithymia represents a constant trait.     

Using a combined blocking procedure to teach color discrimination to a child with autism

A combined blocking procedure was used to teach a child with autism to select two colors on request. First, two color cards were placed at fixed locations on a table and the experimenter repeatedly requested the child to touch one of the colors. After 10 consecutive correct selections, the child was asked to touch the other color. Blocks of trials with each color were systematically thinned until requests were presented randomly with few errors. Subsequently, the location of the selection cards was systematically alternated until the child was able to touch the correct card when both requests and card positions were presented in random fashion.     

The free and cued selective reminding test: Validation for mild cognitive impairment and Alzheimer's disease

The International Working Group on Alzheimer's disease (AD) suggested the free and cued selective reminding test (FCSRT) to assess memory, as it showed high sensitivity and specificity in the differentiation of AD from healthy controls and other dementias. The FCSRT involves the use of selective reminding with semantic cueing in memory assessment. This study aims to validate the FCSRT for mild cognitive impairment (MCI) and AD through the analysis of the diagnostic accuracy and the suggestion of cut‐off scores. Patients were classified into two groups according to standard criteria: MCI (n = 100) and AD (n = 70). A matched control group (n = 101) of cognitively healthy subjects was included. The reliability and the validity of the FCSRT were analysed on the immediate (IR) and delayed (DR) recalls. The Cronbach's alpha was 0.915 for the IR and 0.879 for the DR. The total recall measures revealed good areas under the curve for MCI (IR: .818; DR: .828) and excellent for AD (IR: .987; DR: .991). Furthermore, the MCI group was subdivided with respect to a non‐similar/similar AD pattern of impairment, with almost half of the subjects showing an AD‐like decline. This analysis represents a novel contribution regarding the properties of the FCSRT in illustrating the heterogeneity of MCI at baseline. The FCSRT has proved to be a very useful tool in the characterization of the memory impairment of the AD spectrum.     

Effects of Interest,Thematic Congruence,and Typicality on Memory for Television,Radio, and Press Advertisements of New Products

Little is known about how the content of advertisements is remembered. We studied how product interest, thematic congruence between advertisement and programme, and the typicality of the elements of an advertisement affect memory for new product ads in television, radio, and printed media. Participants were exposed to a single type of media with two embedded ads. After a filler task, they completed a true/false recognition task. In television and radio, accuracy was higher for the interesting product ads. In three experiments, we found no effect of thematic congruence, and the standard effect of typicality. In printed media, where participants are free to read the ads or not, the differences in hits and false alarms in typicality were due to a change in the response criterion and not to an effect on memory. We conclude that different results can be obtained depending on the exposure to different media. Copyright © 2015 John Wiley & Sons, Ltd.     

The benefits of retail therapy: Making purchase decisions reduces residual sadness

People often shop when feeling sad, but whether and why shopping reduces residual (lingering) sadness remains an open question. Sadness is strongly associated with a sense that situational forces control the outcomes in one's life, and thus we theorized that the choices inherent in shopping may restore personal control over one's environment and reduce residual sadness. Three experiments provided support for our hypothesis. Making shopping choices helped to alleviate sadness whether they were hypothetical (Experiment 1) or real (Experiment 2). In addition, all experiments found support for the underlying mechanism of personal control restoration. Notably, the benefits of restored personal control over one's environment do not generalize to anger (Experiments 2 and 3), because anger is associated with a sense that other people (rather than situational forces) are likely to cause negative outcomes, and these appraisals are not ameliorated by restoring personal control over one's environment.     

History of Religious Delusions and Psychosocial Functioning Among Mexican Patients with Paranoid Schizophrenia

The association between global functionality and religiosity among patients from developing and predominantly Catholic countries warrants attention. To compare religiosity and psychosocial functioning in Mexican schizophrenia patients with and without a history of religious delusions, seventy-four patients with paranoid schizophrenia were recruited. Patients with a history of religious delusions had more psychiatric hospitalizations and poorer psychosocial functioning compared with those without a history of religious delusions. No differences emerged between groups in the total scores of religiosity scales. A history of religious delusions rather than religiosity itself may have an influence on psychosocial functioning among Mexican patients with schizophrenia.     

A Replication of the Reker and Cousins’ Study About the Complementarity Between the Purpose-In-Life Test (PIL) and the Seeking of Noetic Goals (SONG) Among Spanish Young People

The main aim of this study was to replicate the Reker and Cousins’ (1979) work about the complementarity between the the Purpose-In-Life Test (PIL), which indicates the degree to which the person has found meaning and purpose in life (presence of meaning), and the Seeking of Noetic Goals (SONG), which measures the degree to which the person is motivated to find meaning and purpose in life (search for meaning). Participants were 349 Spanish undergraduates (224 women, 64.20 %, and 125 men, 35.80 %) between 18 and 26 years old, M = 20.81, SD = 2.17. Principal Component Analysis showed eight factors: four mainly related to the presence of meaning and four mainly related to the search for meaning. The PIL contributed four factors to presence of meaning, whereas the SONG contributed four factors to the search for meaning. The results confirmed the factorial structure, internal consistency, and validity of both scales and their complementarity.     

Group CBT for Externalizing Disorders in Urban Schools: Effect of Training Strategy on Treatment Fidelity and Child Outcomes

Public schools are an ideal setting for the delivery of mental health services to children. Unfortunately, services provided in schools, and more so in urban schools, have been found to lead to little or no significant clinical improvements. Studies with urban school children seldom report on the effects of clinician training on treatment fidelity and child outcomes. This study examines the differential effects of two levels of school-based counselor training: training workshop with basic consultation (C) vs. training workshop plus enhanced consultation (C +) on treatment fidelity and child outcomes. Fourteen school staff members (counselors) were randomly assigned to C or C +. Counselors implemented a group cognitive behavioral therapy protocol (Coping Power Program, CPP) for children with or at risk for externalizing behavior disorders. Independent coders coded each CPP session for content and process fidelity. Changes in outcomes from pre to post were assessed via a parent psychiatric interview and interviewer-rated severity of illness and global impairment. Counselors in C + delivered CPP with significantly higher levels of content and process fidelity compared to counselors in C. Both C and C + resulted in significant improvement in interviewer-rated impairment; the conditions did not differ from each other with regard to impairment. Groups did not differ with regard to pre- to- posttreatment changes in diagnostic severity level. School-based behavioral health staff in urban schools are able to implement interventions with fidelity and clinical effectiveness when provided with ongoing consultation. Enhanced consultation resulted in higher fidelity. Enhanced consultation did not result in better student outcomes compared to basic consultation. Implications for resource allocation decisions with staff training in EBP are discussed.
