Self-control of feedback during motor learning: accounting for the absolute amount of feedback using a yoked group with self-control over feedback

A traditional control group yoked to a group that self-controls their reception of feedback receives feedback in the same relative and absolute manner. This traditional control group typically does not learn the task as well as the self-control group. Although the groups are matched for the amount of feedback they receive, the information is provided on trials in which the individual may not request feedback if he or she were provided the opportunity. Similarly, individuals may not receive feedback on trials for which it would be a beneficial learning experience. Subsequently, the mismatch between the provision of feedback and the potential learning opportunity leads to a decrement in retention. The present study was designed to examine motor learning for a yoked group with the same absolute amount of feedback, but who could self-control when they received feedback. Increased mental processing of error detection and correction was expected for the participants in the yoked self-control group because of their choice to employ a limited resource in the form of a decreasing amount of feedback opportunities. Participants in the yoked with self-control group committed fewer errors than the self-control group in retention and the traditional yoked group in both the retention and time transfer blocks. The results suggest that the yoked with self-control group was able to produce efficient learning effects and can be a viable control group for further motor learning studies.     

The Anguish of the Korean Woman’s Soul: Feminist Theologians on a Real-Life Issue

This paper explores the conflict between mothers-in-law and daughters-in-law in traditional Korean families. In Korea, mothers-in-law sometimes dominate and even denigrate their daughters-in-law. This situation may be caused by the accumulated frustrations of oppressed Korean women that are then vented against their daughters-in-law, intensifying the suffering of women in Korea. The daughter-in-law is now demeaned not just by the men in the family but also by an older woman in the family who has power over her because of age and her status as the mother of the younger woman’s husband. The two women are both victims of a society dominated by men. Women in this culture tend to view their suffering as their destiny, even though they are pained by the unequal treatment. It is possible for a faith community to accept and heal these damaged souls, but some faith communities hurt the women even more in the name of God or sacred authority. This paper provides an analysis of the reality of women’s predicament in Korea and suggests ways in which theology can be a creative and productive resource for these oppressed persons.     

Mad enough to see the other side: anger and the search for disconfirming information

The current research explored the effect of anger on hypothesis confirmation-the propensity to seek information that confirms rather than disconfirms one's opinion. We argued that the moving against action tendency associated with anger leads angry individuals to seek out more disconfirming information than sad individuals, attenuating the confirmation bias. We tested this hypothesis in two studies of experimentally primed anger and sadness on the selective exposure to hypothesis confirming and disconfirming information. In Study 1, participants in the angry condition were more likely to choose disconfirming information than those in the sad or neutral condition when given the opportunity to read more about a social debate, and reading the disconfirming information affected their subsequent attitude. Study 2 measured participants' opinions and information selection about the 2008 US Presidential Election and their desire to "move against" a person or object. Participants in the angry condition reported a greater tendency to oppose a person or object, which resulted in the attenuation of the confirmation bias.     

Cerebellar-induced apraxic agraphia: a review and three new cases

Apraxic agraphia is a writing disorder due to a loss or lack of access to motor engrams that program the movements necessary to produce letters. Clinical and functional neuroimaging studies have demonstrated that the neural network responsible for writing includes the superior parietal region and the dorsolateral and medial premotor cortex. Recent studies of two cases with atypical lesion localisations in the left thalamus and the right cerebellum support the hypothesis that the written language network is larger than previously assumed. The aim of this study is twofold: (1) to provide a survey of cases of apraxic agraphia published between 1973 and June 2010, and (2) to provide further evidence for a role of the cerebellum in writing via three additional cases who presented with apraxic agraphia after ischemic damage in the cerebellum. Functional neuroimaging studies by means of brain perfusion SPECT showed perfusional deficits in the anatomoclinically suspected supratentorial areas, subserving language dynamics, syntax, naming, writing and executive functioning.     

Do central processing and online processing always concur? Analysis of scene order and proportion effects in broadcast news

This study examines the relationship between the central/peripheral processing of the Elaboration Likelihood Model (ELM) and the online/memory‐based processing of impression formation by analyzing the order and proportion effect of scene valence in broadcast news. A 2 (position of positive scenes: beginning and ending) × 3 (proportion of positive scenes: high, medium & low) between design (N = 158) experiment with political campaign broadcast news stories found evidence of central memory‐based processing, which is inconsistent with the common belief that central and online processing always concur. Four typologies of information processing are proposed based on the study's findings: central online processing, peripheral online processing, central memory‐based processing and peripheral memory‐based processing.

Amotivation and the occupational decision: an investigation of Australian senior high school students

This exploratory study investigated the occupational decision-related processes of senior high school students, in terms of the extent to which they may be amotivated in choosing a future occupation. Data were gathered using a newly developed questionnaire, which was largely adapted from a number of psychometrically proven instruments, and administered to 492 Grade 11 students attending a stratified random sample of six independent high schools in Sydney, Australia. Structural equation modelling was used to analyse the data. The major findings of the study include the development of a new empirically supported model that relates amotivation and vocational decision-related processes. The findings may be used by career advisors, psychologists, educators, and family members to advise and assist amotivated senior high school students to make occupational decisions.     

The Cultural Negotiations of Korean Immigrant Youth

The authors investigated the process of cultural adjustment among 13 Korean immigrant youths using consensual qualitative research (C. E. Hill, B. J. Thompson, & E. N. Williams, 1997). Results indicate that Korean youth are expected to negotiate and shift their identities to meet differing expectations across various interpersonal contexts. Participants also report struggling to balance “American” and “Korean” cultural values and norms and to use social support networks, such as family and friends, to deal with the stress of acculturation.

How do the dynamics of shame influence smartphone addiction of Korean Christian adolescents? A study based on external and internal shame

Individuals with negative feeling such as shame might be vulnerable to smartphone addiction. The present study aimed to explore the relationship of smartphone addiction with external shame and internal shame in a sample of Christian adolescents in Korea. The correlational and causal relationships between Korean Christian adolescents’ smartphone addiction and external shame-including others and God-and internal shame were examined. Through a correlational analysis, the study found that external shame-others, external shame-God, internal shame, and smartphone addiction were all highly correlated with each other. During causal and mediation analyses, it was found that internal shame mediated external shame-others and smartphone addiction and also mediated external shame-God and smartphone addiction. In addition, the study offers a discussion of its finding and suggestions for clinical interventions.
