Robustness of the rule-learning effect in 7-month-old infants: A close,multicenter replication of Marcus et al. (1999)

We conducted a close replication of the seminal work by Marcus and colleagues from 1999, which showed that after a brief auditory exposure phase, 7-month-old infants were able to learn and generalize a rule to novel syllables not previously present in the exposure phase. This work became the foundation for the theoretical framework by which we assume that infants are able to learn abstract representations and generalize linguistic rules. While some extensions on the original work have shown evidence of rule learning, the outcomes are mixed, and an exact replication of Marcus et al.'s study has thus far not been reported. A recent meta-analysis by Rabagliati and colleagues brings to light that the rule-learning effect depends on stimulus type (e.g., meaningfulness, speech vs. nonspeech) and is not as robust as often assumed. In light of the theoretical importance of the issue at stake, it is appropriate and necessary to assess the replicability and robustness of Marcus et al.'s findings. Here we have undertaken a replication across four labs with a large sample of 7-month-old infants (N = 96), using the same exposure patterns (ABA and ABB), methodology (Headturn Preference Paradigm), and original stimuli. As in the original study, we tested the hypothesis that infants are able to learn abstract “algebraic” rules and apply them to novel input. Our results did not replicate the original findings: infants showed no difference in looking time between test patterns consistent or inconsistent with the familiarization pattern they were exposed to.     

Vocal indicators of facilitative interpersonal skills

The facilitative interpersonal skills (FIS) method uses simulations of difficult client moments as a test of helpers' ability to remain therapeutic in therapeutically stressful situations. A total of 135 participants completed the FIS task as part of a training in helping skills and provided verbal responses that were assessed by trained raters for interpersonal skills. Audio recordings of these verbal responses were then analysed acoustically for fundamental frequency (F0), spectral slope and F0 range. Mean F0 and F0 range were more highly associated with trained raters' ratings of FIS for female participants than for male participants, although F0 range was associated with FIS of both males and females. The results suggest that F0 is associated with FIS for females, especially the FIS items that are indicative of emotional expression and verbal fluency. Findings are discussed as possibly indicating that some expression of higher F0 in response to distressed client situations may be part of interpersonal skills, such that more skilled therapists respond to stressful client situations with a higher F0.     

A Comparison of Verbal Response Modes Used by Master's-Level Career Counselors and Other Helpers

The verbal response modes of 4 master's-level career counselors, each in middle sessions of career counseling with 2 adult clients, were categorized and compared with those of other types of helpers. Career counselors primarily used information, direct guidance, paraphrase, and closed question. In comparison with data presented in Hill, Thames, and Rardin (1979) Toro (1986) and Levy (1989) career counselors were most similar to Albert Ellis, mental health professionals, psychologists on radio talk shows, and family practice lawyers in that all frequently used information and direct guidance. They were most dissimilar to Carl Rogers, who used more paraphrase, interpretation, and confrontation.     

Dopamine receptor D4 gene variation predicts preschoolers' developing theory of mind

Individual differences in preschoolers' understanding that human action is caused by internal mental states, or representational theory of mind (RTM), are heritable, as are developmental disorders such as autism in which RTM is particularly impaired. We investigated whether polymorphisms of genes affecting dopamine (DA) utilization and metabolism constitute part of the molecular basis of this heritability. Seventy-three 42- to 54-month-olds were given a battery of RTM tasks along with other task batteries that measured executive functioning and representational understanding more generally. Polymorphisms of the dopamine D4 receptor gene (DRD4) were associated with RTM performance such that preschoolers with shorter alleles outperformed those with one or more longer alleles. However, polymorphisms of the catechol-O-methyl transferase gene (COMT) and the dopamine transporter gene (DAT1) genes were not associated with children's RTM performance. Further tests showed that the association between DRD4 allele length and RTM performance was not attributable to a common association with executive functioning or representational understanding more generally. We conclude that DRD4 receptors, likely via their effects on frontal lobe development and functioning, may represent a neuromaturational constraint governing the stereotypical and universal trajectory of RTM development.     

When Thinking About Work Makes Employees Reach for Their Devices: A Longitudinal Autoregressive Diary Study

Based on the stressor-detachment model, previous research has assumed that work-related ICT use in the evening impairs psychological detachment. However, since most of the studies to date have assessed cross-sectional relationships, little is known about the actual direction of effects. In this 5-day diary study, we implemented a day-level longitudinal model to shed light on the causal relationships between work-related ICT use, detachment, and task progress (N?=?340 employees, N?=?1289 day-level cases). We also investigated the role of unfinished work tasks because we assumed, based on boundary theory, that they are a driving force leading to impaired detachment and work-related ICT use in the evening. Contrary to current research consensus but in line with our expectations, we found that low psychological detachment increased work-related ICT use and task progress. We found no evidence for reversed lagged effects. These results applied both to planned and unplanned ICT use. Furthermore, our results support the notion that unfinished work tasks precede ICT use and detachment. Thus, our findings suggest that work-related ICT use should not be treated as a stressor in its own right in the stressor-detachment model. Instead, it needs to be investigated as a behavioral outcome that employees engage in when they cannot detach from work.

     

Regulatory modes and time management: How locomotors and assessors plan and perceive time

This research investigated the relationship between regulatory mode orientations (locomotion and assessment), time management behaviours and the perceived control of time. “Locomotion” refers to the aspect of self‐regulation involving the movement from state to state, whereas “assessment” is the comparative aspect of self‐regulation that refers to the critical evaluation of alternative goals and the means for achieving them. The Italian versions of the Time Management Behavior Scale and the Perceived Control of Time Scale, as well as the Locomotion and Assessment Regulatory Modes Scales were administered to 339 Italian participants (249 students and 90 employees). The results supported the notion that locomotors and assessors differ in the ways they perceive the control of time. Locomotion was found to be positively related to perceived control of time. In contrast, assessment was negatively related to perceived control of time. Furthermore, the two time management dimensions of setting goals and priorities and preference for organisation were shown to mediate the relationship between locomotion and perceived control of time, whereas assessment proved to be unrelated to all time management behaviours. These findings highlight the importance of regulatory modes for human behaviour regarding time management and perceived control of time.
