A Comparative Effectiveness Study of Two High-Frequency Word Interventions: Traditional Drill and WordSheets

Traditional drill and practice (TDP) has been shown to be both effective and efficient for increasing word recognition. WordSheets (WS) is a novel drill procedure similar to TDP with two key differences: (a) WS increases opportunities to respond, which may increase efficiency and (b) WS present instructional stimuli in a context that more closely resembles actual reading passages, which may enhance generalization to connected text. The study sought to compare the effectiveness and efficiency of TDP and WS in a sample of first-grade students (n = 27) identified by their teachers as struggling readers. Results indicated that, although WS led to significantly more opportunities to respond, it was both less effective and efficient than TDP with regard to cumulative retention. However, there were no significant differences across interventions in regard to the maintenance or generalization of treatment gains. Limitations and implications of the current study for school-based professionals are discussed.     

The Ethics of Smart Pills and Self-Acting Devices: Autonomy,Truth-Telling,and Trust at the Dawn of Digital Medicine

Digital medicine is a medical treatment that combines technology with drug delivery. The promises of this combination are continuous and remote monitoring, better disease management, self-tracking, self-management of diseases, and improved treatment adherence. These devices pose ethical challenges for patients, providers, and the social practice of medicine. For patients, having both informed consent and a user agreement raises questions of understanding for autonomy and informed consent, therapeutic misconception, external influences on decision making, confidentiality and privacy, and device dependability. For providers, digital medicine changes the relationship where trust can be verified, clinicians can be monitored, expectations must be managed, and new liability risks may be assumed. Other ethical questions include direct third-party monitoring of health treatment, affordability, and planning for adverse events in the case of device malfunction. This article seeks to lay out the ethical landscape for the implementation of such devices in patient care.     

Contextual connections within puns: effects on perceived humor and memory

The supposition that perceived humor or cleverness would be enhanced by adding separate content to the alternative meanings of a pun was explored, using Tom Swifties as the research vehicle. Because detecting a punning word relationship might induce arousal, requiring more effort and attentional resources for processing than noting a contextual connection, memory strength for adverbs was also examined using a recognition procedure. Five studies were conducted in which college students were asked to judge 24 Swifties (content counterbalanced across participants) in which presence of pun and context were manipulated. The punning relationship was primarily responsible for perceived humor and cleverness. Presence of a pun also enhanced memory strength (d') as long as the familiarization task focused on humor and cleverness. Coherent context enhanced perceived cleverness inconsistently. It was suggested that a coherent contextual connection may make a greater contribution in more lengthy forms of pun-based word play, such as fables or "shaggy dog" stories.     

Birthweight-discordance and differences in early parenting relate to monozygotic twin differences in behaviour problems and academic achievement at age 7

This longitudinal monozygotic (MZ) twin differences study explored associations between birthweight and early family environment and teacher-rated behaviour problems and academic achievement at age 7. MZ differences in anxiety, hyperactivity, conduct problems, peer problems and academic achievement correlated significantly with MZ differences in birthweight and early family environment, showing effect sizes of up to 2%. As predicted by earlier research, associations increased at the extremes of discordance, even in a longitudinal, cross-rater design, with effect sizes reaching as high as 12%. As with previous research some of these non-shared environmental (NSE) relationships appeared to operate partly as a function of SES, family chaos and maternal depression. Higher-risk families generally showed stronger negative associations.     

Friends, porn, and punk: sensation seeking in personal relationships, internet activities, and music preference among college students

One hundred thirty-eight college students completed a questionnaire assessing level of sensation seeking, number of close and casual friends, Internet usage, liking certain styles of music, and genre of music listened to most often. It was found that the number of casual and close friends was positively associated with sensation seeking. Individuals who reported using the Internet to get sex-oriented material, download or play music, play games, and chat/instant message with friends in the previous 24 hours had higher levels of sensation seeking. Liking punk, heavy metal, and reggae music were related to higher levels of sensation seeking. Higher sensation seeking was also associated with spending more time listening to punk music.     

Categorical and dimensional reports of experienced affect to emotion-inducing pictures in depression

Self-reported affect to positive and negative emotional pictures was contrasted in people with major depressive disorder (MDD) and never-depressed control participants (n = 25 in each group). The results revealed significant differences in response to positive images (reduced arousal, less pleasant valence, decreased happiness, increased sadness) in MDD but no clear group differences in response to negative stimuli. Extending earlier findings of reduced responsiveness to positive, but not negative, stimuli in MDD (D. M. Sloan, M. E. Strauss, S. W. Quirk, & M. Satajovik, 1997; D. M. Sloan, M. E. Strauss, & K. L. Wisner, 2001), the data indicate that blunted response to positive stimuli is found when both categorical and dimensional ratings are elicited. Further, the data replicate earlier findings of elevated sadness reports to positive stimuli (J. Rottenberg, K. L. Kasch, J. J. Gross, & I. H. Gotlib, 2002), which may reflect broader difficulties in regulating emotions in MDD.     

Investigator ratings of ADHD symptoms during a randomized, placebo-controlled trial of atomoxetine: a comparison of parents and teachers as informants

This study compared investigator ratings of ADHD symptoms based on interviews with parents and teachers during a doubleblind, placebo-controlled study of atomoxetine. Investigators completed the ADHD Rating Scale: Investigator (ADHDRS-I) based on separate semistructured interviews with the primary caretaker and teacher of the participant. Interviews were conducted at Visits 2 to 7 during a double-blind treatment protocol comparing atomoxetine (N= 10) and placebo (N= 6). Both parent and teacher-based ratings were sensitive to change in ADHD symptoms with atomoxetine treatment. Parent-based assessment differentiated significantly between treatment with atomoxetine and placebo, whereas teacher-based assessment was less sensitive to change. Parents and teachers showed good agreement on change in ADHDRS-I scores. Investigator ratings based on parent- and teacher-report were sensitive to change in symptoms of ADHD during treatment with atomoxetine. Despite good agreement between parent- and teacher-based ratings of symptom change, parent-based ADHD symptom ratings are more sensitive to symptom change.     

Do behavioral disturbances in persons with Alzheimer's disease predict caregiver depression over time?

Random effects models were used to examine the association between behavioral disturbances in persons with Alzheimer's disease (N = 90) and caregiver depressive symptoms at 2-month intervals over an 18-month period. There was substantial variability in trajectories of change in caregiver depressive symptoms over time but no systematic increase in distress despite increased severity of dementia symptoms. Total behavioral disturbances were associated with higher levels of caregiver depressive symptoms: this effect was primarily attributable to aggressive behaviors. No consistent departure from linearity was evident in the relationship between behavior and depression over time.     

Judgments of remembering: the revelation effect in children and adults

When items on a recognition test are presented as a series of increasingly complete fragments rather than being presented initially in their fully intact form, adults' judgments of recognition exhibit an increased tendency to judge items as "old," an illusion of recognition referred to as the revelation effect. The present study used pictorial stimuli to test for a revelation effect with 4-year-olds, 8-year-olds, and adults (N = 76). A reliable revelation effect was found at all ages tested, indicating that the complex fluency-of-processing discrepancy detection and attribution mechanisms thought to be responsible for the effect function similarly across an age range from 4-years-of-age through adulthood. It was also found that the recognition decisions of the 8-year-olds and the adults were affected by how quickly they were able to identify a picture during the revelation phase of the recognition test. This effect was not found with the 4-year-olds, suggesting an age difference in the awareness and strategic use of an implicit memory effect when making explicit judgments of recognition.
