The complex relationship between conscious/unconscious learning and conscious/unconscious knowledge: The mediating effects of salience in form–meaning connections

This study investigates how implicit and explicit learning and knowledge are associated, by focusing on the salience of target form–meaning connections. The participants were engaged in incidental learning of artificial determiner systems that included grammatical rules of [± plural] (a taught rule), [± actor] (a more salient hidden rule), and [± animate] (a less salient hidden rule). They completed immediate and delayed post-tests by means of a two-alternative forced-choice task with subjective judgments of source attributions. Awareness during the learning phase was identified through analysis of thinking aloud protocols. The results did not support a one-to-one relation between either explicit learning and conscious knowledge, or implicit learning and unconscious knowledge; rather, they indicated that implicit and explicit learning are intricately linked to conscious and unconscious knowledge mediated by the salience of form–meaning connections in target items. This result also suggests the possibility of the later emergence of knowledge without any conscious awareness of it.

Differential contributions of implicit and explicit learning mechanisms to various contextual cues in dual adaptation

The ability to switch between different visuomotor maps accurately and efficiently is an invaluable feature to a flexible and adaptive human motor system. This can be examined in dual adaptation paradigms where the motor system is challenged to perform under randomly switching, opposing perturbations. Typically, dual adaptation doesn’t proceed unless each mapping is trained in association with a predictive cue. To investigate this, we first explored whether dual adaptation occurs under a variety of contextual cues including active follow-through movements, passive follow-through movements, active lead-in movements, and static visual cues. In the second experiment, we provided one group with a compensatory strategy about the perturbations (30° CW and 30° CCW rotations) and their relationships to each context (static visual cues). We found that active, but not passive, movement cues elicited dual adaptation. Expectedly, we didn’t find evidence for dual adaptation using static visual cues, but those in the Instruction group compensated by implementing aiming strategies. Then, across all experimental conditions, we explored the extent by which dual learning is supported by both implicit and explicit mechanisms, regardless of whether they elicited dual adaptation across all the various cues. To this end, following perturbed training, participants from all experiments were asked to either use or ignore the strategy as they reached without visual feedback. This Process Dissociation Procedure teased apart the implicit and explicit contributions to dual adaptation. Critically, we didn’t find evidence for implicit learning for those given instructions, suggesting that when explicit aiming strategies are implemented in dual adaptation, implicit mechanisms are likely not involved. Thus, by implementing conscious strategies, dual adaptation can be easily facilitated even in cases where learning would not occur otherwise.

EPILOGUE

In this commentary, we summarize the findings of the seven included studies that examined implicit language aptitude from various perspectives and highlight issues to be resolved in the validation of this new construct in second language research. We start by providing an overview of the contributions of the studies. We then identify the lack of convergent validity of the measures of implicit aptitude reported in the included studies and problematize the equally varied nature of the measurement of implicit knowledge—the outcome variable of aptitude research—and related concepts. In particular, by drawing on empirical evidence and theoretical claims, we attempt to clarify the relationships between implicit and explicit knowledge, implicit and explicit learning, and implicit and explicit instruction. Next, we draw attention to the interactions reported by the included studies between aptitude and outcome measures and between aptitude and instruction type, emphasizing the value and importance of interactional research. We conclude by making recommendations for future research.

Understanding implicit and explicit learning in adolescents with and without anorexia nervosa

Background Cognitive disturbances such as impairments in learning are thought to play a role in adult Anorexia Nervosa (AN). It is remains unclear to what extent these disturbances result from starvation of the brain, or relate to an abnormal premorbid cognitive profile. This study investigates learning processes in adolescents with AN, hypothesizing that implicit learning is intact, as found previously in explicit learning tasks. Secondly, we hypothesized that anxiety and depression symptoms, inherent to AN, are associated to learning processes in AN. Methods In total 46 adolescents diagnosed with AN and 44 control participants were administered an implicit category learning task in which they were asked to categorize simple perceptual stimuli (Gabor patches) based on a linear integration (i.e., an implicit task) of orientation and spatial frequency of the stimulus. A subgroup of adolescents (n = 38) also completed a task assessing explicit learning. Results Model-based analyses indicated that adolescents with AN performed significantly more accurately compared to their healthy peers regardless of whether they used the optimal strategy or not. Depression and anxiety did not relate to learning performance in the AN group. Conclusions Overall, our findings of augmented implicit and explicit learning in adolescents with AN corroborate recent studies that suggested higher stimulus-response learning during prediction error paradigms. Learning disturbances in adult AN may then be at least partly due to long-term malnourishment, highlighting the importance of early recognition and refeeding in treatments for AN.

Are you mentoring or coaching? Definitions matter

© The Author(s) 2020. New library and information science professionals, without previous experience in information organizations, are often left adrift, unsure how to apply theory or best practice to a new work environment. To bridge this gap, mentoring and coaching opportunities are often employed (or mandated) to provide new practitioners with required skills, knowledge, or networking. There are opportunities to harness implicit and explicit learning through experiences and interactions through mentoring and coaching. Definitions of mentoring and coaching in the profession are often used interchangeably when discussing the growth and development of an individual. This leads to the following questions: How do librarians define both mentoring and coaching? How do mentoring and coaching relate to professional development? To address the research question, 47 semi-structured interviews were conducted with librarians in Canada, New Zealand, and the United States between 2015 and 2016. Participants were asked about their mentoring and coaching experiences. During the interviews, participants were asked questions about their experiences as a mentor or mentee. In addition, participants were asked to define both “mentoring” and “coaching.” The authors used an inductive approach to data analysis, and interviews were coded by category.

Curling Coaches’ Understanding of Their Role in Developing Performance Under Pressure Through Skill Acquisition

There are few studies examining coaches’ awareness of their role in developing performance under pressure. This study has explored the application of implicit and explicit learning theory for skill execution under pressure through the understanding of coaches. Seven curling coaches who teach adult novices were interviewed using a semistructured approach. Interpretative phenomenological analysis was used to explore their experiences and beliefs around skill acquisition and pressure. Key factors that emerged from the analysis were the coaches’ lack of awareness of their role in developing skill execution under pressure and the importance of coach education in creating that awareness. The recognition of the pressure that players will face in games and the potential for implicit techniques to be employed by the coaches demonstrated positive prospects for the application of implicit/explicit skill acquisition theory. The coaches’ experiences highlighted aspects unique to curling that will need to be considered in progressing the study’s findings. The distinction between skill setup and execution was also raised by coaches and requires further study to identify whether it impacts the effectiveness of building robust skills and the resulting coaching advice. The study provides recommendations for application of the theory and suggestions for future research.
