Examining the Preferred Self-Controlled KR Schedules of Learners and Peers During Motor Skill Learning

In many practical situations, learners are provided with feedback in the form of knowledge of results (KR) by a peer. However, when peers provide KR is currently unknown. When given the opportunity to request KR in a self-controlled manner, some participants have reported a preference for requesting KR after good performances. Alternatively, peers may provide KR in a different fashion. Subsequently, a discrepancy between the learner's desire to receive KR and when a peer provides KR may arise. In our study, peer- and self-controlled KR schedules were compared. Participants were peers who controlled KR (PC; 8), learners with peers (P-L; 8), or learners with self-control (SC; 8). Participants in the two learning groups (P-L and SC groups) completed a serial-timing task with a goal time of 2500 ms. Absolute error data on KR and no-KR trials along with self-reports indicate that participants with self-control preferred KR after good trials and peers preferred to provide KR after both good and bad trials equally. Results from the delayed retention test indicated that peer-controlled learners were more consistent (i.e., in terms of variable error) than the self-control group.     

The cerebellum: Its role in language and related cognitive and affective functions

The traditional view on the cerebellum as the sole coordinator of motor function has been substantially redefined during the past decades. Neuroanatomical, neuroimaging and clinical studies have extended the role of the cerebellum to the modulation of cognitive and affective processing. Neuroanatomical studies have demonstrated cerebellar connectivity with the supratentorial association areas involved in higher cognitive and affective functioning, while functional neuroimaging and clinical studies have provided evidence of cerebellar involvement in a variety of cognitive and affective tasks. This paper reviews the recently acknowledged role of the cerebellum in linguistic and related cognitive and behavioral–affective functions. In addition, typical cerebellar syndromes such as the cerebellar cognitive affective syndrome (CCAS) and the posterior fossa syndrome (PFS) will be briefly discussed and the current hypotheses dealing with the presumed neurobiological mechanisms underlying the linguistic, cognitive and affective modulatory role of the cerebellum will be reviewed.     

Future time perspective and career decisions: The moderating effects of affect spin

This study investigated the impact of future time perspective on two career decision-making variables and the role of affect spin as a moderator. 98 Korean undergraduate students completed questionnaires of future time perspective, career decision-making self-efficacy, and career choice anxiety. Using experience sampling method (ESM), we also collected students' affective experiences during 7 consecutive days and computed affect variability, namely affect spin. Hierarchical regression analyses showed that career decision-making self-efficacy and career choice anxiety were positively predicted by future time perspective and that affect spin moderated the relationship between future time perspective and both career decision-making self-efficacy scale and career choice anxiety respectively. We discussed the implications of the moderating role of affect spin, advantages of the ESM method, and practical suggestions for career counseling and supervision.     

Impression management motive and voice: Moderating effects of self‐monitoring,self‐efficacy,and voice instrumentality

The purpose of this study is to examine how employees’ impression management motive influences their voice by considering dispositional and situational variables. Drawing on the theory of self‐motive, we hypothesized that voice would be more positively related to impression management motive than prosocial motive. In addition, based on the interactional approach of motive and trait and trait activation theory, we hypothesized that the relationship between impression management motive and voice would be moderated by self‐monitoring, self‐efficacy, and voice instrumentality. Using a sample of 307 supervisor–subordinate dyads from South Korea, we found that, although prosocial motive had a positive influence on voice, impression management motive had a stronger influence on voice than prosocial motive. We also found that the positive influence of impression management motive on voice was stronger for employees with high levels of self‐monitoring, self‐efficacy, and voice instrumentality. This study helps verify the boundary conditions as to when impression management motive is strongly related to voice. In addition, this study will provide theoretical clues for resolving the inconsistent findings on the relationship between impression management motive and voice.     

When a good fit can be bad

How should we select among computational models of cognition? Although it is commonplace to measure how well each model fits the data, this is insufficient. Good fits can be misleading because they can result from properties of the model that have nothing to do with it being a close approximation to the cognitive process of interest (e.g. overfitting). Selection methods are introduced that factor in these properties when measuring fit. Their success in outperforming standard goodness-of-fit measures stems from a focus on measuring the generalizability of a model's data-fitting abilities, which should be the goal of model selection.
