Audio‐visual speech in noise perception in dyslexia

Individuals with developmental dyslexia (DD) may experience, besides reading problems, other speech‐related processing deficits. Here, we examined the influence of visual articulatory information (lip‐read speech) at various levels of background noise on auditory word recognition in children and adults with DD. We found that children with a documented history of DD have deficits in their ability to gain benefit from lip‐read information that disambiguates noise‐masked speech. We show with another group of adult individuals with DD that these deficits persist into adulthood. These deficits could not be attributed to impairments in unisensory auditory word recognition. Rather, the results indicate a specific deficit in audio‐visual speech processing and suggest that impaired multisensory integration might be an important aspect of DD.     

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.     

Peer interaction in child care centres at 15 and 23 months: stability and links with children's socio-emotional adjustment

In this longitudinal study, 70 children were observed during 90 min of free play in their child care centres at 15 and 23 months of age. The children (39 boys and 31 girls) attended 51 different care groups in 39 centres. The occurrence and stability of peer interactions in the second year of life and their relations to children's socio-emotional adjustment were examined. The frequency of children's negative initiatives towards peers showed significant inter-individual stability from 15 to 23 months and predicted child aggressive/disruptive behaviour at 23 months as rated by professional caregivers in child care. Involvement in positive interactions with peers, and particularly positive responses to peer behaviours at 15 months, predicted well-being in child care at 23 months as rated by professional caregivers. The frequency of negative initiatives towards peers significantly increased and the frequency of positive responses to peer behaviours significantly decreased from 15 to 23 months.     

Response modes, decision processes and decision outcomes

Until recently, research on riskless multiattribute decision making has generally ignored a distinction among response modes, i.e. the type of response required of the decision maker. This neglect persisted in spite of the results of early studies on preference reversals in gambles, which showed a distinct difference between the decision outcomes of choice and those of judgment. This article examines the effects of response modes in relation to two explanations proposed in recent response mode studies: the compatibility hypothesis and the response mode continuum. An experiment was conducted with a process tracing technique (information boards), in which 104 subjects made decisions on the quality of student papers submitted for publication. Four response modes were compared: selecting, rejecting, classifying, and ranking of alternatives. In addition, information load was manipulated. Response mode influenced both the decision process and the decision outcome. The results are interpreted as supporting the response mode continuum idea, but not the compatibility hypothesis. A classification of response modes is proposed.     

Learning where to feed: the use of social information in flower-visiting Pallas’ long-tongued bats (<Emphasis Type="Italic">Glossophaga soricina</Emphasis>)

Social learning is a widespread phenomenon among vertebrates that influences various patterns of behaviour and is often reported with respect to foraging behaviour. The use of social information by foraging bats was documented in insectivorous, carnivorous and frugivorous species, but there are little data whether flower-visiting nectarivorous bats (Phyllostomidae: Glossophaginae) can acquire information about food from other individuals. In this study, we conducted an experiment with a demonstrator-observer paradigm to investigate whether flower-visiting Pallas’ long-tongued bats (Glossophaga soricina) are able to socially learn novel flower positions via observation of, or interaction with, knowledgeable conspecifics. The results demonstrate that flower-visiting G. soricina are able to use social information for the location of novel flower positions and can thereby reduce energy-costly search efforts. This social transmission is explainable as a result of local enhancement; learning bats might rely on both visual and echo-acoustical perception and are likely to eavesdrop on auditory cues that are emitted by feeding conspecifics. We additionally tested the spatial memory capacity of former demonstrator bats when retrieving a learned flower position, and the results indicate that flower-visiting bats remember a learned flower position after several weeks.     

Verbal facilitation effects instead of verbal overshadowing in face memory of 4- to 6-year olds

Research on eye witness memory in older children and adults revealed that verbally describing unfamiliar faces impairs later recognition of these faces, known as the “verbal overshadowing effect”. The aim of this study was to investigate whether a verbal overshadowing effect occurs in 4- to 6-year olds, too, and whether visualization (i.e., drawing the seen face) might elicit a visual overshadowing effect. Instead of a verbal overshadowing effect, a verbal facilitation effect was revealed with verbal intelligence being a significant predictor for recognition accuracy in the verbalization group but not in the control group. No effect of visualization was observed on recognition accuracy. Potential explanations for the results are discussed.     

Approach and avoidance relationship goals and couples’ nonverbal communication during conflict

Approach relationship goals are pursued in order to achieve desirable outcomes, whereas avoidance relationship goals are pursued to prevent undesirable outcomes in relationships. We investigated how partners’ approach and avoidance relationship goals are related to their nonverbal communication during conflict. A sequential analysis of observational data from 365 couples (28,470 observations) revealed that individuals with more (vs. fewer) approach goals displayed more positive involvement (e.g., head nods, smiles) and less avoidant withdrawal (e.g., shaking head, folded arms). The reverse pattern emerged for avoidance goals. Furthermore, women (but not men) matched their partner's positive involvement to a greater extent the more approach goals and the fewer avoidance goals they pursued. In contrast, approach/avoidance relationship goals were not associated with how much individuals matched their partner's avoidant withdrawal. Results suggest that relationship goals are related to partners’ nonverbal communication and the extent to which women match their partner's positive involvement during conflict.     

Let’s twist again! Embodiment effects in spatial judgments on human figures rotated along a vertical axis

We investigated whether individuals used mental rotation and embodiment for arm laterality judgments of human figures that were stepwise rotated from back view to front view along a vertical axis. In Experiment 1, figures’ heads were always shown in profile, while only the bodies were rotated. Judgments were faster and more correct when figures were presented in back view compared to front view, but the relation between reaction times (RTs) and rotation angles was not strictly linear. In addition, judgments on figures in anatomically possible postures were better than on figures in impossible postures. In Experiment 2, figures’ heads were turned together with their body. RTs and rotation angles were linearly related. Results suggest that individuals use both mental rotation and a more direct matching between their own body and that of the figures, when making arm laterality judgments of human figures that are rotated along a vertical axis.     

Two sides of the career resources coin: Career adaptability resources and the impostor phenomenon

Considering the impostor phenomenon (IP) as an important psychological construct in the context of career development requires a theoretical grounding. Using the career construction model of adaptation as a guiding framework, we investigated how the IP is related to adaptive readiness (represented by core self-evaluations), career adaptability resources, and adapting responses, namely, career planning, career decision-making difficulties, career exploration, and occupational self-efficacy. We used parallel multiple mediation modeling to investigate specific indirect effects through concern, control, curiosity, confidence, and the IP. We conducted an online study with 289 university students. Results indicated a positive effect of core self-evaluations on career planning, career exploration, and occupational self-efficacy and a negative effect on career decision-making difficulties through adaptability resources. The IP emerged as a “maladaptability” resource: That is, it might be a hindrance to adaptive coping and behavior and consequently promote maladaptive coping and behavior by decreasing career planning and occupational self-efficacy and increasing career decision-making difficulties. Supplementary negative effects of the IP on adaptability resources are discussed.     

Stability and Change in Emotion-Organization

This investigation is based on the assumption that a person's emotion-organization is a stable, idiosyncratic property of great importance in determining that person's distinctive characteristics. The two main issues are whether a stable emotion-organization can be found in the turmoil of everyday life and whether life events affect this organization. A sequence of 323 daily assessments of an emotion list by a 26-year-old woman justifies the conclusion that stable, meaningful clusters of emotions can be distinguished. Highly emotional events have an enduring effect upon the organization of these clusters.
