Attention-Deficit Hyperactivity Disorder: The Medicalization of Misbehavior

During the past decade, there has been an increase in the diagnosis and treatment of Attention-Deficit Hyperactivity Disorder (ADHD). This syndrome, typically diagnosed in childhood, is characterized by inattention, hyperactive motor behavior, and distractibility. Current prevalence rates obtained in various countries generally exceed the 3–5% reported by DSM-IV. Reasons for increased ADHD prevalence include changes in diagnostic standards, overlap between ADHD and other externalizing disorders, nonspecific behavioral criteria, and the rapid effects of stimulant medication on cognitive functioning. However, social, cultural, and economic factors may also contribute to increased diagnosis. ADHD has become a common topic in the lay media. Popular discussions of ADHD may serve as a metaphoric expression of social anxieties, particularly with respect to children. At the same time, ADHD has rapidly become incorporated into a medical model, with emphasis on pharmacological treatment. Reductions in mental health and educational services, as well as economic pressures of managed care, may also contribute to medicalization of behavioral problems. Collaboration between psychologists and primary care physicians can lead to more accurate diagnosis and appropriate treatment of ADHD and related disorders.     

Doing philosophy is doing its history

While Curley argues that we need to know the history of philosophy so as not to avoid important alternatives to contemporary proposals, I argue that philosophy is an essentially historical enterprise. Unlike science, philosophy cannot forget its history. Not to know the history of philosophy is not to understand why the questions we seek to answer are worth answering or asking.     

Emotion recognition in children with Fetal Alcohol Spectrum Disorders

There is a limited amount of research that examines social-emotional functioning in children with Fetal Alcohol Spectrum Disorder (FASD), and the majority of it relies on parent and teacher reports of social impairments. Because these provide broad measures of social function, they fail to elucidate the underlying specific skills with which this group of children has difficulty. The current study examines emotion-recognition abilities in children with FASD, as it plays a central role in social interaction. Participants were 22 children with diagnosed FASD (ages 8–14), and age- and gender-matched typically developing controls. Tasks included measures of emotion recognition from three nonlinguistic modalities: facial expressions, emotional tone of voice, and body positioning and movement. Participant’s parents completed measures of adaptive and behavioral function that were related to children’s performance on aspects of emotion recognition. Overall, the results show that children with FASD have more difficulties with emotion recognition than typically developing age-matched peers, but these difficulties may not be clinically significant (e.g., smaller effect size) or may be specific to the age of the individual exhibiting the emotion (i.e., child vs. adult). These results are discussed in the context of previous studies.     

The frequency of simultaneous disfluency and phonological errors in children: A preliminary investigation

The frequency of simultaneous disfluency and phonological errors was examined in seven young English-speaking children exhibiting coexisting stuttering and phonological disorders. Data were gathered during 30 minutes of mother-child conversation and analyzed in three parts: (1) stuttering, (2) phonological errors, and (3) stuttering and phonological error co-occurrence. Results indicated that stuttering did not occur more frequently on syllables with phonological errors than on syllables without phonological errors. However, the frequency of disfluency on word-initial consonant clusters with phonological errors was significantly higher than on word-initial consonant clusters without phonological errors. Theoretical and clinical implications are discussed.     

Repeated testing in eyewitness memory: a means to improve recall of a negative emotional event

Participants viewed either a violent, arousing film or a non-violent, control version of the same film. After viewing the film, they made three successive attempts to recall details of the event. Participants who were exposed to the negative emotional event were better than control participants at recalling details of the event itself, but they were worse at recalling details that preceded or followed the violence. Both groups of participants recalled significantly more information over successive recall attempts, suggesting that memory impairment due to arousal can be alleviated by repeated testing. Repeated testing was also associated with a small but reliable increase in memory intrusions. The implications of these findings for research on hypermnesia and on the relationship between arousal and memory are discussed. © 1998 John Wiley & Sons, Ltd.     

Using equivalence‐based instruction to teach the visual analysis of graphs

Previous research has demonstrated low rater agreement when visually inspecting trends in single‐subject design graphs (see Wolfe, Seaman, & Drasgow, 2016). Didactic instruction of visual analysis of practicing behavior analysts has resulted in generally poor and unreliable performances (Danov & Symons, 2008; Diller, Barry, & Gelino, 2016). Therefore, a refined instructional technology to improve the reliability among behavior analysts is warranted. Developing research has focused on the application of equivalence‐based instruction (Brodsky & Fienup, 2018; Rehfeldt, 2011) for a variety of complex human behaviors. In the current study, equivalence‐based instruction was used to train four participants to identify functional relations displayed in five different classes of graphs. Training resulted in the formation of five equivalence classes by all participants consisting of three members (graph, functional relation rule, and functional relation statement). In addition, the skills were maintained for up to 2 weeks and generalized to novel graphs.     

Barriers to Adherence to Child Assessment Recommendations

We conducted a one-year follow-up study of child psychoeducational assessment cases to examine whether and how the assessments were helpful to families. The current report focuses on parents’ views of their child’s assessment as well as the parents’ adherence with the written recommendations provided to them following their child’s assessment. Fifty-one of 72 eligible parents whose child received an assessment in an urban, Midwest university clinic participated. Based on semistructured interviews with the parents about the assessment recommendations, we grouped the recommendations and any barriers to adherence the parents mentioned into categories, and we also rated the clarity and complexity of the recommendations. Findings showed that, on average, parents identified the assessment process as useful and attempted or fully adhered to 71.5?% of recommendations. Parents reported the lowest adherence when referrals were recommended for their child to be seen by other professionals such as a pediatrician or psychiatrist; and they cited significantly more stigma barriers for recommendations to seek counseling/therapy or psychotropic medication than for recommendations pertaining to changes at home or school. Higher parental compliance was predicted by a combination of parents reporting fewer barriers and receiving more home based recommendations. The results support the utility of psychological assessments from parents’ perspectives and suggest ways in which psychologists may increase the likelihood that parents will adhere to their recommendations.     

Preservation of long-term memory and synaptic plasticity despite short-term impairments in the Tc1 mouse model of Down syndrome

Down syndrome (DS) is a genetic disorder arising from the presence of a third copy of the human chromosome 21 (Hsa21). Recently, O’Doherty and colleagues in an earlier study generated a new genetic mouse model of DS (Tc1) that carries an almost complete Hsa21. Since DS is the most common genetic cause of mental retardation, we have undertaken a detailed analysis of cognitive function and synaptic plasticity in Tc1 mice. Here we show that Tc1 mice have impaired spatial working memory (WM) but spared long-term spatial reference memory (RM) in the Morris watermaze. Similarly, Tc1 mice are selectively impaired in short-term memory (STM) but have intact long-term memory (LTM) in the novel object recognition task. The pattern of impaired STM and normal LTM is paralleled by a corresponding phenotype in long-term potentiation (LTP). Freely-moving Tc1 mice exhibit reduced LTP 1 h after induction but normal maintenance over days in the dentate gyrus of the hippocampal formation. Biochemical analysis revealed a reduction in membrane surface expression of the AMPAR (α-amino-3-hydroxy-5-methyl-4-propionic acid receptor) subunit GluR1 in the hippocampus of Tc1 mice, suggesting a potential mechanism for the impairment in early LTP. Our observations also provide further evidence that STM and LTM for hippocampus-dependent tasks are subserved by parallel processing streams.     

A Pilot Study of Culturally Adapted Cognitive Behavior Therapy for Hispanics with Major Depression

The purpose of this study was to evaluate a culturally adapted cognitive-behavioral treatment (CBT) for major depression among Hispanics in primary care. Cultural adaptations were applied based on a range of cultural considerations described in the literature. Fifteen Hispanic primary care patients with major depression were enrolled. All participants received the 12-session intervention and completed baseline, posttreatment, and 6-month follow-up assessments. Four participants (27%) dropped out of the treatment. Analyses focused on changes from baseline functioning using a Wilcoxon Signed Rank Test. Results showed significant reductions in depressive, anxious, and somatic symptoms at posttreatment and 6-month follow-up. Mean reduction of depressive symptoms at posttreatment was 57%. Findings of acceptable treatment retention rates and clinically meaningful reductions in depressive symptoms showed promise for this intervention to treat Hispanics with major depression. Future studies should conduct a more rigorously controlled evaluation of this intervention.
