Predictive Validity of Adult Attachment Measures in Relation to Emotion Regulation Behaviors in Marital Interactions

This study examined the predictive validity of 2 assessment approaches to adult attachment in relation to emotion regulation behaviors during marital conflict interactions. Both partners of 40 couples completed the Adult Attachment Style self-report (AAS; C. Hazan & P. Shaver, 1987), the Adult Attachment Questionnaire (AAQ; J. A. Simpson, 1990), the Adult Attachment Interview (AAI; C. George, N. Kaplan, & M. Main, 1985), and a videotaped interaction during which the partners engaged in a problem-solving discussion. The discussions were coded by means of the Interactional Dimensions Coding System (IDCS; D. Julien, H. J. Markman, & K. M. Lindhal, 1989). Results showed that AAI classification predicted proactive emotion regulation behaviors, whereas the AAS and the AAQ did not. Issues concerning the predictive validity of current measures of adult attachment are discussed.     

Parenting and toddler self-regulation in low-income families: What does sleep have to do with it?

Toddlerhood is a sensitive period in the development of self-regulation, a set of adaptive skills that are fundamental to mental health and partly shaped by parenting. Healthy sleep is known to be critical for self-regulation; yet, the degree to which child sleep alters interactive child–parent processes remains understudied. This study examines associations between observed parenting and toddler self-regulation, with toddler sleep as a moderator of this association. Toddlers in low-income families (N = 171) and their mothers were videotaped during free play and a self-regulation challenge task; videos were coded for mothers’ behavior and affect (free play) and toddlers’ self-regulation (challenge task). Mothers reported their child's nighttime sleep duration via questionnaire. Results revealed significant Sleep × Maternal Negative Affect and Sleep × Maternal Negative Control interactions. Children who did not experience negative parenting had good self-regulation regardless of their nighttime sleep duration. For children who did experience negative parenting, self-regulation was intact among those who obtained more nighttime sleep, but significantly poorer among children who were getting less nighttime sleep. Thus, among children who were reported to obtain less nighttime sleep, there were more robust associations between negative parenting and poorer self-regulation than among toddlers who were reported to obtain more sleep.     

The behavioral effects of enriched housing are not altered by serotonin depletion but enrichment alters hippocampal neurochemistry

To assess a possible role for serotonin in the mediation of the behavioral changes induced by enriched housing conditions (EC), adult female Long-Evans rats sustaining a serotonin depletion (150 microg of 5,7-dihydroxytryptamine, icv) and sham-operated rats were housed postoperatively for 30 days in enriched (12 rats/large cage containing various objects) or standard housing conditions (2 rats/standard laboratory cage). Thereafter, anxiety responses (elevated plus-maze), locomotor activity (in the home-cage), sensori-motor capabilities (beam-walking task), and spatial memory (eight-arm radial maze) were assessed. Monoamine levels were subsequently measured in the frontoparietal cortex and the hippocampus. Overall, EC reduced anxiety-related responses, enhanced sensori-motor performance and improved the memory span in the initial stage of the spatial memory task. Despite a substantial reduction of serotonergic markers in the hippocampus (82%) and the cortex (74%), these positive effects of EC were not altered by the lesion. EC reduced the serotonin levels in the ventral hippocampus (particularly in unlesioned rats: -23%), increased serotonin turnover in the entire hippocampus (particularly in lesioned rats: +36%) and augmented the norepinephrine levels in the dorsal hippocampus (+68% in unlesioned and +49% in lesioned rats); no such alterations were found in the frontoparietal cortex. Our data suggest that an intact serotonergic system is not a prerequisite for the induction of positive behavioral effects by EC. The neurochemical changes found in the hippocampus of EC rats, however, show that the monoaminergic innervation of the hippocampus is a target of EC.     

ETUDE COMPARATIVE DES EVALUATIONS COLLECTIVES ET INDIVIDUELLES DE LA PENSEE FORMELLE

The purpose of the present study is to examine the effects of different individual and group testing procedures on the success rate obtained by subjects on different formal problems. Four testing conditions were compared: a clinical interview; an individual interview without intervention; a group test with a demonstration of the material; and a group paper-and-pencil test. The four conditions are defined according to several variables that were deemed important for the explanation of potential performance outcomes. All subjects were administered the following four Piagetian derived tasks: a projection of shadows task; a permutation task; an equilibrium in the balance task; and an interrupter combinations task. According to the general hypothesis, subject performance should be optimal for the clinical interview and decline gradually as the assumed advantages of this method are systematically removed, i.e., counterquestioning of the examiner, retrials, subject-examiner interactions, familiarization with the material, etc. The results show that there are performance differences between the conditions, but mainly across the individual and group situations. However, mean ranks obtained from each condition indicate that the facilitating variables identified in the first three conditions have a certain influence on subject performance. Implications regarding a choice of a valid mesurement of formal thought are discussed.     

Exploring the motivation jungle: predicting performance on a novel task by investigating constructs from different motivation perspectives in tandem

Different theoretical viewpoints on motivation make it hard to decide which model has the best potential to provide valid predictions on classroom performance. This study was designed to explore motivation constructs derived from different motivation perspectives that predict performance on a novel task best. Motivation constructs from self-determination theory, self-regulation theory, and achievement goal theory were investigated in tandem. Performance was measured by systematicity (i.e. how systematically students worked on a problem-solving task) and test score (i.e. score on a multiple-choice test). Hierarchical regression analyses on data from 259 secondary school students showed a quadratic relation between a performance avoidance orientation and both performance outcomes, indicating that extreme high and low performance avoidance resulted in the lowest performance. Furthermore, two three-way interaction effects were found. Intrinsic motivation seemed to play a key role in test score and systematicity performance, provided that effort regulation and metacognitive skills were both high. Results indicate that intrinsic motivation in itself is not enough to attain a good performance. Instead, a moderate score on performance avoidance, together with the ability to remain motivated and effectively regulate and control task behavior, is needed to attain a good performance. High time management skills also contributed to higher test score and systematicity performance and a low performance approach orientation contributed to higher systematicity performance. We concluded that self-regulatory skills should be trained in order to have intrinsically motivated students perform well on novel tasks in the classroom.     

Illness perceptions and self-care behaviours in the first years of living with type 2 diabetes; does the presence of complications matter?

Objective: To assess illness perceptions, self-care behaviours and their relationship in recently diagnosed type 2 diabetes mellitus (T2DM) patients with and without diabetes-related complications.

Design: Cross-sectional survey among 192 recently diagnosed T2DM patients of whom 23% reported the presence of diabetes-related complications. Illness perceptions and self-care were assessed by the Revised Illness Perception Questionnaire (IPQ-R) and the revised Summary of Diabetes Self-Care Activities (SDSCA) measure.

Results: Generally, participating patients perceived T2DM as a chronic, but relatively controllable condition with minor consequences. In the presence of complications, however, T2DM was perceived as more unpredictable with more (serious) consequences and less controllable by self-care or medical treatment. Furthermore, engagement in exercise and foot care was reported more often by patients with complications. Self-care was related to certain illness perception dimensions, and interactions between perceptions and complications were found.

Conclusion: T2DM patients in the first years of their illness are often recommended to make lifestyle changes in the absence of noticeable diabetes-related symptoms or complaints. As many T2DM patients do not seem to perceive their condition to be serious and postpone lifestyle changes until diabetes-related complications appear, a major challenge for professionals is to convince asymptomatic patients of the importance of self-care.     

Predictive influence of phonological processing, morphological/syntactic skill, and naming speed on spelling performance

This paper focuses on the predictive influence of phonological awareness, morphological/syntactic skill, and naming speed on spelling. The retrospective study correlated spelling performance in a group of 199 French-speaking children at the end of grade 2 with earlier capacities for phonemic manipulation, morphological/syntactic correction, and naming speed, assessed at the end of grade 1. The results are consistent with an integrative model that challenges the unitary phonological disorder hypothesis and confirmed that in French, as in other languages, naming speed is an independent predictor of reading performance.     

Processes of inference, schizotypal thinking, and obsessive-compulsive behaviour in a normal sample

Previous research has shown inferential confusion as measured by the Inferential Confusion Questionnaire to be related to obsessive-compulsive symptoms. A total of 108 participants (41 men and 66 women) from a normal population in The Netherlands (M age = 46 yr., SD = 15.5) completed a package of questionnaires measuring inferential confusion, schizotypal symptoms, and obsessive-compulsive behaviour. As expected, scores for both inferential confusion and schizotypal symptoms were significantly related to those for obsessive-compulsive behaviour. In addition, analysis showed that inferential confusion and schizotypal symptoms shared common variance, but both predicted an independent portion of the variance in obsessive-compulsive behaviour while controlling for neuroticism. The present results call for further inquiry into the role of inferential confusion and schizotypal thinking in obsessive-compulsive behaviour.     

Pitch Cues for the Recognition of Yes-No Questions in French

Linguistic studies of the intonation of Yes–No questions in French show that, in questions containing more than two stress groups, interrogative intonation is characterized by a sequence of lowered pitches or downstepped tones which precede the final rise. The gating paradigm was used here to determine whether subjects listening to French NP utterances containing three stress groups could indicate whether the utterance was an statement or a question before the final rise was heard. Although the task was difficult, findings indicate that listeners can in fact to a certain extent, recognize with mid confidence ratings, the intonational device of a question while they were hearing the downstepped tones preceding the final rise.
