The nature of hemispheric specialization for prosody perception

Recent evidence suggests a relative right-hemispheric specialization for emotional prosody perception, whereas linguistic prosody perception is under bilateral control. It is still unknown, however, how the hemispheric specialization for prosody perception might arise. Two main hypotheses have been put forward. Cue-dependent hypotheses, on the one hand, propose that hemispheric specialization is driven by specialization for the non-prosody-specific processing of acoustic cues. The functional lateralization hypothesis, on the other hand, proposes that hemispheric specialization is dependent on the communicative function of prosody, with emotional and linguistic prosody processing being lateralized to the right and left hemispheres, respectively. In the present study, the functional lateralization hypothesis of prosody perception was systematically tested by instructing one group of participants to evaluate the emotional prosody, and another group the linguistic prosody dimension of bidimensional prosodic stimuli in a dichotic-listening paradigm, while event-related potentials were recorded. The results showed that the right-ear advantage was associated with decreased latencies for an early negativity in the contralateral hemisphere. No evidence was found for functional lateralization. These findings suggest that functional lateralization effects for prosody perception are small and support the structural model of dichotic listening.     

The Role of Perfectionism in Relation to an Intervention to Reduce Anxious and Depressive Symptoms in Children

Research has demonstrated an association between perfectionism and depressive and anxious symptoms in children. We examined whether a school-based program targeting anxious and depressive symptoms would reduce perfectionism, and whether perfectionism would interfere with intervention outcomes. The participants were 78 school-age children identified as at-risk for anxiety and/or depression. At-risk children took part in a randomized controlled trial of a school-based intervention program. Levels of perfectionism, depression, and anxiety were assessed at pre-treatment (Time 1) and again at post-treatment (Time 2) after participating in either a cognitive behavioral group or a structured activity group. Participation in either group was associated with significant reductions in overall levels of self-oriented perfectionism, anxious symptoms, and depressive symptoms. Supplementary analyses indicated that pre-treatment self-oriented perfectionism influenced post-treatment depression scores, suggesting that perfectionism interferes with treatment outcome. Perfectionism in children appeared amenable to group-based intervention, and identifying perfectionism may be important for treating children with depressive symptoms.     

Laboratory vs. naturalistic prospective memory task predictions: young adults are overconfident outside of the laboratory

ABSTRACT

This study investigated whether individuals can predict their future prospective memory (PM) performance in a lab-based task and in a naturalistic task. Metacognitive awareness was assessed by asking participants to give judgments-of-learning (JOLs) on an item-level for the prospective (that something has to be done) and retrospective (what to do) PM component. In addition, to explore whether giving predictions influences PM performance, we compared a control group (without predictions) to a prediction group. Results revealed that giving predictions did not change PM performance. Moreover, participants were underconfident in their PM performance in the lab-based task, while they were overconfident in the naturalistic task. In addition, item-level JOLs indicated that they were inaccurate in predicting what items they will recall or not, but only for the prospective component of the PM task. As for the retrospective component, they were equally accurate in both task settings. This study suggests a dissociation of metacognitive awareness for PM according to both task setting and processing component.     

Improving Interaction Competencies With Children—A Pilot Feasibility Study to Reduce School Corporal Punishment

High prevalence rates of corporal punishment in schools worldwide and the associated negative mental health issues show the need for interventions addressing this problem. Yet, so far there are very few intervention studies aimed at altering corporal punishment administered by teachers, particularly in low- or middle-income countries.

To conduct a feasibility study of the newly developed intervention approach, Interaction Competencies with Children for Teachers (ICC-T)—a training workshop designed to prevent corporal punishment and improve the teacher-student relationship.

The 1-week ICC-T intervention was conducted with 30 teachers in a Tanzanian primary school. Participants filled out a survey before, directly after, and 3 months following the intervention.

The widespread use of corporal punishment indicated strong demand for a preventive intervention. The feasibility of ICC-T was good: Despite challenging conditions, implementation of the training and participants’ acceptance was high. Further, participants reported a good integration of the training’s core elements in their daily working routine, improvements in the teacher-student relationships, and in the students’ behavior.

ICC-T shows a promising feasibility in the Tanzanian teacher sample. These encouraging results highlight the need for further studies testing the efficacy, sustainability, and effects of ICC-T on the students’ well-being.     

The everyday dynamics of rumination and worry: precipitant events and affective consequences

ABSTRACT

Rumination and worry are two perseverative, negatively valenced thought processes that characterise depressive and anxiety disorders. Despite significant research interest, little is known about the everyday precipitants and consequences of rumination and worry. Using an experience sampling methodology, we examined and compared rumination and worry with respect to their relations to daily events and affective experience. Participants diagnosed with Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD), co-occurring MDD–GAD, or no diagnosis carried an electronic device for one week and reported on rumination, worry, significant events, positive affect (PA), and negative affect (NA). Across the clinical groups, occurrences of everyday events predicted subsequent increases in rumination, but not worry. Further, higher momentary levels of rumination, but not worry, predicted subsequent decreases in PA and increases in NA. Thus, in these clinical groups, rumination was more susceptible to daily events and produced stronger affective changes over time. We discuss implications for theory and clinical intervention.     

Looking ahead from age 6 to 13: A deeper insight into the development of planning ability

Planning ability gradually increases throughout childhood. However, it remains unknown whether this is attributable to global factors such as an increased ability and willingness to inhibit premature, impulsive responding, or due to the availability of specific planning operations, such as being able to mentally plan ahead more steps (‘search depth’) or to derive a clear temporal order of goals by the task layout (‘goal hierarchy’). Here, we studied the development of planning ability with respect to these global and problem‐specific aspects (search depth and goal hierarchy) of performance in 178 children from 6 to 13 years using the Tower of London task. As expected, global performance gradually developed with age. In accordance, planning durations increasingly reflected global problem demands with longer pre‐planning in harder problems. Furthermore, specific planning parameters revealed that children were increasingly capable of mentally searching ahead more steps. In contrast, the ability to derive a goal hierarchy did not show age‐related changes. While the global development of planning performance and adaptive planning durations were proposed to primarily reflect enhanced self‐monitoring, the specific increase in search depth across childhood that most likely proceeds until young adult age represents more directly planning‐related processes. Thus, development of planning ability is supported by multiple contributions.
