Effects of diurnal variation on the Test of Variables of Attention performance in young adults with attention-deficit/hyperactivity disorder

The Test of Variables of Attention (TOVA) is a continuous performance test that assesses attention, impulsivity, and processing speed. Continuous performance tests are used in the assessment of attention-deficit/hyperactivity disorder (ADHD) in children and adults. TOVA norms are based on a morning administration, and any TOVA administered after 1:00 p.m. is flagged as potentially invalid. Whereas the testing time recommendations make sense for pediatric samples, it is unclear whether they are appropriate for young adults, who typically show significant phase delay in their diurnal rhythms. The current study explores the impact of time of day on TOVA performance in young adults with ADHD. Participants were randomly assigned to either morning or afternoon administration. We found no significant diurnal variation in TOVA performance. We also found no interaction between diurnal preference and time of day of administration. Night owls endorsed more inattention symptoms on a self-report measure than more intermediate individuals but actually made significantly fewer omission (inattention) errors on the TOVA. Self-reported symptoms of inattention showed moderate, significant correlations with various TOVA performance indices. Self-reported symptoms of hyperactivity and impulsivity, however, showed no relationship to TOVA performance. These results suggest that the TOVA can be administered to adults with ADHD outside of the hours recommended in the manual without significantly compromising the interpretative validity of test score interpretation. Thus, a TOVA report that is consistent with ADHD should not be dismissed simply because it was administered in the late afternoon.     

Identifying Cognitive and Interpersonal Predictors of Adolescent Depression

Emerging research has begun to examine cognitive and interpersonal predictors of stress and subsequent depression in adolescents. This research is critical as cognitive and interpersonal vulnerability factors likely shape expectations, perspectives, and interpretations of a given situation prior to the onset of a stressor. In the current study, adolescents (n?=?157; boys=64, girls=93), ages 12 to 18, participated in a 6-month, multi-wave longitudinal study examining the impact of negative cognitive style, self-criticism, and dependency on stress and depression. Results of time-lagged, idiographic multilevel analyses indicate that depressogenic attributional styles (i.e., composite score and weakest link approach) and self-criticism predict dependent interpersonal, but not noninterpersonal stress. Moreover, the occurrence of stress mediates the relationship between cognitive vulnerability and depressive symptoms over time. At the same time, self-criticism predicts above and beyond depressogenic attributional styles (i.e., composite and weakest link approach). In contrast to our hypotheses, dependency does not contribute to the occurrence of stress, and additionally, no gender differences emerge. Taken together, the findings suggest that self-criticism may be a particularly damaging vulnerability factor in adolescence, and moreover, it may warrant greater attention in the context of psychotherapeutic interventions.     

Asymmetries Between Positives and Negatives

How people react to negatives (what they dislike) is not always symmetric to how they react to positives (what they like). We propose a theoretical framework that links three potentially general types of positive–negative asymmetries: asymmetry in prediction errors (people err more when predicting others' attitudes about positives than about negatives), asymmetry in consensus (people agree more among themselves about negatives than about positives), and asymmetry in base rates (there are more negatives than positives). Our theory further explores a moderator for these asymmetries – importance of the stimulus to the self: greater importance engenders greater positive–negative asymmetries. We provide empirical evidence for our theory and discuss the boundaries and implications of our propositions and findings.     

Integrating mindfulness as self-care into counselling and psychotherapy training

Aim: Within the last 10 years, mindfulness has quickly moved into the mainstream of behavioural medicine, psychotherapy, and counselling. This article examines the potential of applying mindfulness practices to the training of counsellors and psychotherapists. Method: Several qualitative research projects conducted over the past nine years are summarised. Findings: Mindfulness training can enhance the physical and psychological wellbeing of trainees. Implications for training: Mindfulness training is a specific way that training programmes can teach students strategies of self-care that can help prevent burnout, compassion fatigue, and vicarious traumatisation.     

Later language development in narratives in children with perinatal stroke

Studies of young children with unilateral perinatal stroke (PS) have confirmed the plasticity of the developing brain for acquiring language. While recent studies of typically developing children have demonstrated the significant development of language well into adolescence, we know little regarding the course of language development in the PS group as they mature. Will children with PS continue to show the same remarkable plasticity that they exhibited at younger ages? In the present paper we investigate later language and discourse in children with perinatal stroke (ages 7–16) using spoken personal narrative as the discourse context. In contrast to the findings of the discourse studies of younger children with PS, children with left hemisphere lesions made more morphological errors, used less complex syntax and fewer syntactic types than controls; they also produced more impoverished story settings. In contrast, those with right hemisphere lesions performed comparably to controls, except in their impoverished use of complex syntax. The findings provide insight into the nature of later spoken language development in these children, revealing both the nature and extent of neuroplasticity for language as well as potential regional biases.     

Transfer between Picture Books and the Real World by Very Young Children

Picture book reading is a very common form of interaction between parents and very young children. Here we explore to what extent young children transfer novel information between picture books and the real world. We report that 15- and 18-month-olds can extend newly learned labels both from pictures to objects and from objects to pictures. However, the degree to which they do so is affected by iconicity—how much the objects and pictures resemble one another. The children in these studies more often extended the labels between picture and object when realistic photographs and drawings were involved than less realistic cartoons. These results show that higher levels of perceptual similarity between symbol and referent make the referential relation more transparent, thereby helping children transfer information between them. Thus, the educational function of early picture book interactions may best be served with realistic illustrations.     

The role of task difficulty and affect activation level in the use of affect as information

The current research examined task difficulty and affect activation level as factors that determine the relevance of affect as information in a performance context. Participants viewed a series of pictures designed to elicit an affective state that was high or low in activation and positive or negative in valence. They completed an easy or difficult anagram task and then rated their satisfaction with their performance. Analyses revealed that low activation affect was used as information for judging one's performance on the difficult task and high activation affect was used as information for judging one's performance on the easy task. In these cases, the valence of participants' affect influenced their judgments about their performance, such that positive affect resulted in greater satisfaction. These findings suggest that affective states with activation levels that match one's typical level of energy after a particular task are seen as more relevant for judging one's performance.
