Cognitive-Behavioral Therapy for Insomnia Co-Morbid with Hearing Impairment: A Randomized Controlled Trial

The purpose of the current study was to examine the effects of cognitive behavior therapy (CBT-I) for insomnia on patients with insomnia co-morbid with hearing impairment. A randomized controlled design was used with a 3-month follow-up. Thirty-two patients with insomnia co-morbid with hearing impairment were randomized to either CBT-I or a waitlist condition (WLC). The primary outcome was insomnia severity. Secondary outcomes were sleep diary parameters, dysfunction, anxiety, and depression. Compared to WLC, CBT-I resulted in lower insomnia severity at post-treatment and at follow-up (d = 1.18–1.56). Relative to WLC, CBT-I also led, at both assessment points, to reduced total wake time (d = 1.39) and increased sleep restoration (d = 1.03–1.07) and sleep quality (d = 0.91–1.16). Both groups increased their total sleep time, but no significant group difference emerged. Compared to WLC, CBT-I resulted in higher function (d = 0.81–0.96) and lower anxiety (d = 1.29–1.30) at both assessment points. Neither CBT-I nor WLC led to improvement on depression. Based on the Insomnia Severity Index, more CBT-I (53–77%) than WLC participants (0–7%) were treatment responders. Also, more CBT-I (24%) than WLC participants (0%) remitted. In patients with insomnia co-morbid with hearing impairment, CBT-I was effective in decreasing insomnia severity, subjective sleep parameters, dysfunction, and anxiety. These findings are in line with previous results on the effects of CBT-I in other medical conditions.     

Demonstrator skill modulates observational aversive learning

Learning to avoid danger by observing others can be relatively safe, because it does not incur the potential costs of individual trial and error. However, information gained through social observation might be less reliable than information gained through individual experiences, underscoring the need to apply observational learning critically. In order for observational learning to be adaptive it should be modulated by the skill of the observed person, the demonstrator. To address this issue, we used a probabilistic two-choice task where participants learned to minimize the number of electric shocks through individual learning and by observing a demonstrator performing the same task. By manipulating the demonstrator’s skill we varied how useful the observable information was; the demonstrator either learned the task quickly or did not learn it at all (random choices). To investigate the modulatory effect in detail, the task was performed under three conditions of available observable information; no observable information, observation of choices only, and observation of both the choices and their consequences. As predicted, our results showed that observable information can improve performance compared to individual learning, both when the demonstrator is skilled and unskilled; observation of consequences improved performance for both groups while observation of choices only improved performance for the group observing the skilled demonstrator. Reinforcement learning modeling showed that demonstrator skill modulated observational learning from the demonstrator’s choices, but not their consequences, by increasing the degree of imitation over time for the group that observed a fast learner. Our results show that humans can adaptively modulate observational learning in response to the usefulness of observable information.     

Delis-Kaplan Executive Function System

The purpose of the current study was to examine the performance of children with and without ADHD in time reproduction tasks involving varying durations and modalities. Twenty children with ADHD and 20 healthy controls completed time reproduction tasks in three modalities (auditory, visual, and a unique combined auditory/visual condition) and six durations (1 second, 4 seconds, 12 seconds, 24 seconds, 48 seconds, and 60 seconds). Consistent with our predictions, we found main effects of group (participants with ADHD were significantly less accurate than those without ADHD), duration (accuracy decreased as temporal duration increased), and modality (responses in the combined condition were more accurate than those in the auditory condition, which in turn were more accurate than those in the visual condition). Furthermore, predicted interactions between group and duration (the discrepancy in performance between the two groups grew as temporal duration increased), and group and modality (the modality effect was of greater for participants with ADHD) were supported. A marginal, nonsignificant interaction between group, modality, and duration was also found. These findings are discussed in relation to current theory on the nature of cognitive deficits evident in individuals with ADHD, and methodological limitations are noted.     

Test Review: Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV)

Objective: Evaluate neuropsychological functioning in children with non-syndromic cleft of the lip and/or palate (NSCL/P) through profile variance within type of cleft and comparisons to controls.

Methods: Children ages 7 to 17 years participated; 66 had a diagnosis of NSCL/P and 87 were healthy controls. Neuropsychological tests of language, visual-perceptual, executive functioning, and memory skills were administered. Between- and within-group differences were assessed.

Results: Within cleft types, children with NSCLP had an even profile with equal Verbal and Performance IQ (VIQ and PIQ, respectively). Children with non-syndromic cleft palate only (NSCP) had significantly lower VIQ than PIQ, while children with non-syndromic cleft lip only (NSCL) showed a nonsignificant trend for higher VIQ than PIQ. Overall, subjects with NSCL/P performed lower on measures of expressive language and verbal memory than controls.

Conclusions: While deficits in verbal and memory skills for children with NSCL/P remain apparent, there is still uncertainty around the possible influence of cleft type on the pattern of deficits.     

Developmental normative data for the Baron-Hopkins Board test of spatial location memory

Developmentally appropriate domain-specific tests with strong psychometric properties for preschoolers are lacking and infrequently developed. Baron’s modification of the Hopkins Board test (B-HB) to assess spatial location learning and recall in 3- and 6-year-old children has shown promise in the study of young children born prematurely. Current study data were analyzed on 172 typically developing children at age 3 years and 193 at age 6 years, born at term (≥ 37 weeks; ≥ 2500 grams). Statistically significant gender differences were found and data stratification of T-scores and percentile ranks are provided for each of the eight B-HB measures. The B-HB’s strong interrater reliability (99.5%), low-to-moderate test-retest reliability across the 3-year age span, Pearson correlations showing criterion validity, and differential functioning from other selective attention and visuospatial/visuoperceptual tests provide initial normative data for this novel measure of spatial location memory in young children.     

A COMPARISON OF READING COMPREHENSION PROCESSES IN POLISH AND ENGLISH*

Two experiments in Polish replicated several conditions in English experiments on reading comprehension processes. In Polish syntactic information is represented primarily by morphology and in English primarily by word order. Lexical, syntactic + semantic, within-syntactic class, between-syntactic class, semantic, and factual information were violated in stories. Native speakers read the stories aloud and the protocols were scored for increases in production time around violations. The disruptions in oral reading caused by the syntactic violations were relatively larger and occurred earlier in Polish than in English. The semantic and factual violations produced broader disruptions in English than in Polish. Reading comprehension processes varied to meet the cognitive demands imposed by how the available information was represented. Polish readers adopted a focused strategy and English readers a more diffused strategy.     

Detection and apparent taste intensity of salt—acid mixtures in two media

Gustatory responses to mixtures of sodium chloride and citric acid were measured in two media of dispersion, distilled water and green bean puree, by fifteen experienced Ss. The two psychophysical methods employed, detection thresholds and apparent taste intensity, showed good agreement. Salt sharply depressed apparent sourness in both media, as well as interfering with detection of sourness. Citric acid influenced apparent saltiness in a complex manner, dependent upon concentration, media, method, and tile individual S. In water, lower concentrations of acid generally enhanced and higher concentrations depressed saltiness. Within both media, half the Ss indicated an enhancement of saltiness with increasing acidity and half indicated the reverse. Higher acid levels interfered with detection of saltiness. This biphasic response to binary taste stimuli are discussed and compared with pertinent findings from previous literature.

Internet-provided cognitive behaviour therapy of posttraumatic stress symptoms following childbirth—a randomized controlled trial

The aim of this study was to analyse the effects of trauma-focused guided Internet-based cognitive behaviour therapy for relieving posttraumatic stress disorder (PTSD) symptoms following childbirth, a problem that about 3% women encounter postpartum. Following inclusion, 56 traumatized women were randomized to either treatment or to a waiting list control group. Primary outcome measures were the Traumatic Event Scale (TES) and Impact of Event Scale—Reversed (IES-R). Secondary measures were Beck depression inventory II, Patient Health Questionnaire (PHQ-9), Beck Anxiety Inventory, Quality Of Life Inventory and the EuroQol 5 Dimensions. The treatment was guided by a clinician and lasted eight weeks and comprised eight modules of written text. The between-group effect size (ES) was d = .82 (p < .0001) for the IES-R. The ES for the TES was small (d = .36) and not statistically significant (p = .09). A small between-group ES (d = .20; p = .02) was found for the PHQ-9. The results from pre- to post-treatment showed large within-group ESs for PTSD symptoms in the treatment group both on the TES (d = 1.42) and the IES-R (d = 1.30), but smaller ESs in the control group from inclusion to after deferred treatment (TES, d = .80; IES-R d = .45). In both groups, the treatment had positive effects on comorbid depression and anxiety, and in the treatment group also on quality of life. The results need to be verified in larger trials. Further studies are also needed to examine long-term effects.
