Vision and action: the effect of visual feedback on infants' exploratory behaviors

The role of visual feedback during object exploration and manipulation was examined in 8-month-old infants. Infants appeared to maximize the stimulating properties of objects by producing sound when possible, and engaged in more activities in the light compared to the dark.     

Reenactment of televised content by 2-year olds: toddlers use language learned from television to solve a difficult imitation problem

Parents commonly label objects on television and for some programs, verbal labels are also provided directly via voice-over. The present study investigated whether toddlers' imitation performance from television would be facilitated if verbal labels were presented on television via voice-over or if they were presented by parents who were co-viewing with their toddlers. Sixty-one 2-year olds were randomly assigned to one of four experimental groups (voice-over video, parent video, parent video no label, parent live) or to a baseline control condition. Toddlers were tested with novel objects after a 24h delay. Although, all experimental groups imitated significantly more target actions than the baseline control group, imitation was facilitated by novel labels regardless of whether those labels were provided by parents or by voice-over on television. These findings have important implications for toddler learning from television.     

Orienting attention in visual working memory reduces interference from memory probes

Given a changing visual environment, and the limited capacity of visual working memory (VWM), the contents of VWM must be in constant flux. Using a change detection task, the authors show that VWM is subject to obligatory updating in the face of new information. Change detection performance is enhanced when the item that may change is retrospectively cued 1 s after memory encoding and 0.5 s before testing. The retro-cue benefit cannot be explained by memory decay or by a reduction in interference from other items held in VWM. Rather, orienting attention to a single memory item makes VWM more resistant to interference from the test probe. The authors conclude that the content of VWM is volatile unless it receives focused attention, and that the standard change detection task underestimates VWM capacity.     

Combining mindfulness meditation with cognitive-behavior therapy for insomnia: a treatment-development study

This treatment-development study is a Stage I evaluation of an intervention that combines mindfulness meditation with cognitive-behavior therapy for insomnia (CBT-I). Thirty adults who met research diagnostic criteria for Psychophysiological Insomnia (Edinger et al., 2004) participated in a 6-week, multi-component group intervention using mindfulness meditation, sleep restriction, stimulus control, sleep education, and sleep hygiene. Sleep diaries and self-reported pre-sleep arousal were assessed weekly while secondary measures of insomnia severity, arousal, mindfulness skills, and daytime functioning were assessed at pre-treatment and post-treatment. Data collected on recruitment, retention, compliance, and satisfaction indicate that the treatment protocol is feasible to deliver and is acceptable for individuals seeking treatment for insomnia. The overall patterns of change with treatment demonstrated statistically and clinically significant improvements in several nighttime symptoms of insomnia as well as statistically significant reductions in pre-sleep arousal, sleep effort, and dysfunctional sleep-related cognitions. In addition, a significant correlation was found between the number of meditation sessions and changes on a trait measure of arousal. Together, the findings indicate that mindfulness meditation can be combined with CBT-I and this integrated intervention is associated with reductions in both sleep and sleep-related arousal. Further testing of this intervention using randomized controlled trials is warranted to evaluate the efficacy of the intervention for this population and the specific effects of each component on sleep and both psychological and physiological arousal.     

How do Hostile and Emotionally Overinvolved Relatives View Relationships?: What Relatives' Pronoun Use Tells Us

Expressed emotion (EE) has been linked to negative outcomes for a variety of psychiatric illnesses. Despite development of effective interventions to reduce EE, relatively little is known about EE's antecedents or maintaining factors. The present study uses a novel methodology (measurement of pronouns used by relatives during the Camberwell Family Interview [CFI] or a problem-solving interaction with the patient) to explore possible cognitive correlates of EE. Participants were 98 outpatients with obsessive-compulsive disorder or panic disorder with agoraphobia and their primary relative. Results showed that relatives' pronoun use was stable across situations. Relatives' hostility and criticism, as measured by objective coding of relatives' behavior during the CFI and interactions, respectively, were related to relatives' decreased we-focus and increased me-focus in the 2 situations. In contrast to expectations, relatives' emotional overinvolvement was related to their decreased we-focus during CFIs and interactions. Results support the value of using pronouns as a means to explore important aspects of relationship functioning.     

Sensitization and habituation of motivated behavior in overweight and non-overweight children

The rate of habituation to food is inversely related to energy intake, and overweight children may habituate slower to food and consume more energy. This study compared patterns of sensitization, as defined by an initial increase in operant or motivated responding for food, and habituation, defined by gradual reduction in responding, for macaroni and cheese and pizza in overweight and non-overweight 8- to 12-year-old children. Non-overweight children habituated faster to both foods than overweight children (p = .03). All children recovered motivated responding for a new food (chocolate). Overweight children consumed more energy than non-overweight children (p = .0004). Children who showed a sensitization in responding consumed more food (p = .001), and sensitization moderated the effect of overweight on habituation, with slower habituation for overweight children who sensitized (p < .001). This study replicates previous data on overweight/non-overweight differences in habituation of food and energy intake, and provides new information that individual differences in sensitization and habituation of motivated responding to obtain food may be associated with a sustained motivation to eat, resulting in greater energy intake.     

Israeli counsellors facing terrorism: coping and professional development

The current study examined the characteristics and functioning of 12 Israeli school counsellors located at different stages of professional development who worked in schools affected by terrorist attacks. Semi-structured interviews explored the counsellors' professional behaviour, activities, and coping with terror and its effects. Consensual qualitative research analysis revealed five major domains: role definition, organisational characteristics, affective reactions, dilemmas, and barriers and resources. Counsellors at different stages of professional development demonstrated different patterns of behaviour across the domains' categories and subcategories. Implications for research and supervision are discussed.     

Adolescent perceptions of overall family system functioning and parental behaviors

We used a systems perspective to examine relationships between adolescents’ perceptions of overall family system functioning and selected parental behaviors. Self-report questionnaire data from 160 ninth and tenth grade students were analyzed using MANCOVA and discriminant analysis. The results showed two parental behaviors, support and monitoring distinguished between types of overall family system functioning. Adolescents in balanced and moderately balanced overall family functioning reported greater parental support, while adolescents in balanced and extreme overall family functioning reported greater parental monitoring. We present the implications of our findings for parent education and assessment.
