Profils d’apprenti·e·s reflétant des tensions de rôle en formation professionnelle en alternance en Suisse

Role stress among apprentices are a key element in defining the quality of dual vocational education and training. However, few studies have examined the perceptions and importance of role tensions in this particular context. Accordingly, this contribution focuses on the role stress perceived by dual apprentices through a questionnaire survey. Latent profile analyses allowed to distinguish four apprentices’ profiles in terms of perceptions of role stress, ranging from minimal to prominent role stress. Differences in socio-demographic characteristics, motivation for choosing the training, professional identification, and intention to terminate the apprenticeship contract were also identified. The study provides information on the importance of considering apprentices as a heterogeneous population in terms of role stress, but also on the different motivational and identity issues associated with the profiles. Discussing such issues would also improve the learning experience.     

Examining the link between adolescent brain development and risk taking from a social–developmental perspective (reprinted)

The adolescent age period is often characterized as a health paradox because it is a time of extensive increases in physical and mental capabilities, yet overall mortality/morbidity rates increase significantly from childhood to adolescence, often due to preventable causes such as risk taking. Asynchrony in developmental time courses between the affective/approach and cognitive control brain systems, as well as the ongoing maturation of neural connectivity are thought to lead to increased vulnerability for risk taking in adolescence. A critical analysis of the frequency of risk taking behaviors, as well as mortality and morbidity rates across the lifespan, however, challenges the hypothesis that the peak of risk taking occurs in middle adolescence when the asynchrony between the different developmental time courses of the affective/approach and cognitive control systems is the largest. In fact, the highest levels of risk taking behaviors, such as alcohol and drug use, often occur among emerging adults (e.g., university/college students), and highlight the role of the social context in predicting risk taking behavior. Moreover, risk taking is not always unregulated or impulsive. Future research should broaden the scope of risk taking to include risks that are relevant to older adults, such as risky financial investing, gambling, and marital infidelity. In addition, a lifespan perspective, with a focus on how associations between neural systems and behavior are moderated by context and trait-level characteristics, and which includes diverse samples (e.g., divorced individuals), will help to address some important limitations in the adolescent brain development and risk taking literature.     

Package size and perceived quality: The intervening role of unit price perceptions

This research examines how package size can influence quality judgments for packaged goods, and also identifies a price-based mechanism for the observed size–quality relationship. Results from several studies show that a product in a smaller package is rated more favorably than the equivalent product in a larger package. Further, this effect is due to the smaller package being associated with a higher unit price (despite having a lower overall price), which suggests that unit price information is more diagnostic than overall price information when forming judgments of product quality. We also find a theoretically-derived reversal of this effect under conditions in which the greater diagnosticity of unit price is overwhelmed by its lower ease of use. Namely, when overall price is the only explicitly-provided price cue and consumers are too distracted to estimate unit price, a larger package is now rated as being better. Finally, two concluding studies examine the downstream consequences of changes in package size, building off our basic conceptualization to document effects on product choice as well as consumption experience.     

Can children develop a dual identity when immigrant mothers feel homesick? A short-term longitudinal study among Turkish immigrants

Abstract

Turkish immigrant-origin youth in Western Europe often develop strong ethnic and weaker national identities. To advance our understanding of this pattern, we investigated the concurrent development and intergenerational transmission of both identities over time in conjunction with maternal homesickness. Our study was based on a sample of 176 Turkish mother-child dyads from Germany, Norway, and the Netherlands. Mothers (M _t1 = 38 years) reported on their identities and homesickness at T1 and children (M _t1 = 12 years) on their identities at T1 and T2. Our results showed that children’s ethnic and national identities became more incompatible over time, mother’s homesickness strengthened children’s ethnic identities, and mother’s ethnic identities in combination with high levels of homesickness weakened children’s national identities. We conclude that early adolescence is a critical time for Turkish immigrant youth’s identity development and that a focus on parental acculturative stressors can advance ethnic socialization and cultural transmission research.     

Are Automatic Imitation and Spatial Compatibility Mediated by Different Processes?

Automatic imitation or “imitative compatibility” is thought to be mediated by the mirror neuron system and to be a laboratory model of the motor mimicry that occurs spontaneously in naturalistic social interaction. Imitative compatibility and spatial compatibility effects are known to depend on different stimulus dimensions—body movement topography and relative spatial position. However, it is not yet clear whether these two types of stimulus–response compatibility effect are mediated by the same or different cognitive processes. We present an interactive activation model of imitative and spatial compatibility, based on a dual‐route architecture, which substantiates the view they are mediated by processes of the same kind. The model, which is in many ways a standard application of the interactive activation approach, simulates all key results of a recent study by Catmur and Heyes (2011) . Specifically, it captures the difference in the relative size of imitative and spatial compatibility effects; the lack of interaction when the imperative and irrelevant stimuli are presented simultaneously; the relative speed of responses in a quintile analysis when the imperative and irrelevant stimuli are presented simultaneously; and the different time courses of the compatibility effects when the imperative and irrelevant stimuli are presented asynchronously.     

The roles of private speech and inner speech in planning during middle childhood: Evidence from a dual task paradigm

Children often talk themselves through their activities, producing private speech that is internalized to form inner speech. This study assessed the effect of articulatory suppression (which suppresses private and inner speech) on Tower of London performance in 7- to 10-year-olds, relative to performance in a control condition with a nonverbal secondary task. Experiment 1 showed no effect of articulatory suppression on performance with the standard Tower of London procedure; we interpret this in terms of a lack of planning in our sample. Experiment 2 used a modified procedure in which participants were forced to plan ahead. Performance in the articulatory suppression condition was lower than that in the control condition, consistent with a role for self-directed (private and inner) speech in planning. On problems of intermediate difficulty, participants producing more private speech in the control condition showed greater susceptibility to interference from articulatory suppression than their peers, suggesting that articulatory suppression interfered with performance by blocking self-directed (private and inner) speech.     

Is it life or is it Memorex? Video as a representation of reality

This paper offers an overview of research on infants’ early behavior toward televised images, followed by an account of the development of representational competence with video. Several aspects of representation are involved in young children’s understanding and use of video. From a very young age, children form mental representations of the contents of video, making sense of realistic images of familiar things. Children also notice and represent information regarding video itself (e.g., its 2-dimensionality). An important development occurs when children represent the relation between video and reality: at first, toddlers appear to categorize video as separate from reality, but eventually children recognize realistic video images as physical representations (symbols) of events they have not directly perceived. A mature representation of video takes into account genre (e.g., news, drama) and reality status based on recognition that video can (but does not always) represent real events.     

Response inhibition and avoidance of virtual obstacles during gait in healthy young and older adults

Adjustments of preplanned steps are essential for fall avoidance and require response inhibition. Still, inhibition is rarely tested under conditions resembling daily living. We evaluated the ability of young and older adults to modify ongoing walking movements using a novel precision step inhibition (PSI) task combined with an auditory Stroop task.Healthy young (YA, n = 12) and older (OA, n = 12) adults performed the PSI task at 4 individualized difficulty levels, as a single and dual task (DT). Subjects walked on a treadmill by stepping on virtual stepping stones, unless these changed color during approach, forcing the subjects to avoid them. OA made more failures (40%) on the PSI task than YA (16%), but DT did not affect their performance. In combination with increased rates of omitted Stroop task responses, this indicates a “posture first” strategy. Yet, adding obstacles to the PSI task significantly deteriorated Stroop performance in both groups (the average Stroop composite score decreased by 13% in YA and 27% in OA). Largest deficit of OA was observed in rates of incorrect responses to incongruent Stroop stimuli (OA 35% and YA 12%), which require response inhibition. We concluded that the performance of OA suffered specifically when response inhibition was required.     

Task choice and semantic interference in picture naming

Evidence from dual-task performance indicates that speakers prefer not to select simultaneous responses in picture naming and another unrelated task, suggesting a response selection bottleneck in naming. In particular, when participants respond to tones with a manual response and name pictures with superimposed semantically related or unrelated distractor words, semantic interference in naming tends to be constant across stimulus onset asynchronies (SOAs) between the tone stimulus and the picture–word stimulus. In the present study, we examine whether semantic interference in picture naming depends on SOA in case of a task choice (naming the picture vs reading the word of a picture–word stimulus) based on tones. This situation requires concurrent processing of the tone stimulus and the picture–word stimulus, but not a manual response to the tones. On each trial, participants either named a picture or read aloud a word depending on the pitch of a tone, which was presented simultaneously with picture–word onset or 350 ms or 1000 ms before picture–word onset. Semantic interference was present with tone pre-exposure, but absent when tone and picture-word stimulus were presented simultaneously. Against the background of the available studies, these results support an account according to which speakers tend to avoid concurrent response selection, but can engage in other types of concurrent processing, such as task choices.     

Testing a dual-process model of avoidant defenses

Research suggests that the defensive strategy used by people who score high on attachment-related avoidance when they encounter interpersonal threats involves two stages: automatic vigilance followed by effortful avoidance. In two studies we varied stimulus exposure times and cognitive load to determine how attention is regulated by avoidant individuals. Results indicate that avoidant individuals were vigilant toward contempt faces when the faces were presented for 100 ms but quickly disengaged from them when the faces were presented for 750 ms. Moreover, avoidant participants could disengage from contempt faces presented for 750 ms while rehearsing a simple 1-digit number, but not when rehearsing a 7-digit number, suggesting that avoidant disengagement is a cognitively effortful process. Theoretical and practical implications are discussed.
