Recall and Recognition Measures of Paired Associate Learning in Healthy Aging

ABSTRACT

Associate-recognition has received little attention as a potential clinical tool for detecting early Alzheimer's disease (AD). As an important preliminary stage to investigating the paradigm's diagnostic utility, we designed and administered a verbal associate-recognition task to healthy elderly participants (n?=?62) and compared their performance to that on traditional cued-recall PAL. In both test conditions, the stimulus list comprised of a mixture of highly imageable and less imageable word pairs. Overall, performance on the associate-recognition task was superior to that on the cued-recall analogue. This ‘recognition advantage’ was not attributable to the higher baseline or chance guessing rate in the associate-recognition condition, as the size of the recognition advantage varied across learning trials and stimulus imageability. In comparison to performance on the imageable stimuli, performance on the less imageable stimuli was poor in both associate-recognition and cued-recall conditions. Across the delay, performances were more likely to drop in the cued-recall condition than the associate-recognition condition. These results suggest that verbal associate-recognition may be clinically efficacious and better tolerated in elderly populations than traditional cued-recall paradigms. Although these results are encouraging, further research is required to examine the utility of associate-recognition in clinical populations, particularly early AD.     

“Faith Maturity Scale” for Chinese: A Revision and Construct Validation

Using a large sample of Chinese Christians (n = 2,196), we examined the internal structure, reliability, and validity of the Faith Maturity Scale (FMS). Despite its being developed in North America, and for a mainline Protestant population, the FMS was shown to have validity among non-Western, non-mainline Protestants. There is convergent validity with self-reported religious practices and a belief measure of religiosity. Our analyses also confirmed good construct validity with the Big Five personality dimensions, social axioms, attributional style, and quality of life. FMS remained associated with religious practices and high quality of life after personality was statistically controlled. Findings supported that the Chinese version of the FMS assesses the same theoretical construct as does the original scale and that the distinction between the vertical and horizontal dimensions of faith maturity is meaningful.     

The use of reflection-card by elite youth basketball players,head coach and team manager: effects on players’ performance and perceptions of users

The purpose of the present paper was to test the effectiveness of the r-cards in sport performance, and to examine what kind of benefits and challenges the head coach, team manager and female basketball players (N = 12) faced when using the r-cards. Mixed methods were employed to gather specific data to answer the research questions. Inferential statistical analyses were conducted to examine whether players’ performances in terms of their targeted defensive rebound percentage and free-throw percentage differed across the five matches played. No significant differences were found. However, evidence from the qualitative data provides a contrasting but insightful perspective. Subjectively, the r-cards strategy was seen as beneficial because it improved the team’s performance and preparations, helped the players in goal setting, identification of weaknesses, and recognition of effort. In contrast, realistic goal setting, irrelevance of some reflection questions, effort recognition, and feedback to head coach were found challenging in r-cards usage. The paper closes with a critical discussion on the implications for future use of r-cards in the field of sport coaching.     

The Influence of Task Difficulty on Context Effect - Compromise and Attraction Effects

Research in psychology finds strong context effects in consumer behavior and help consumer make up their mind from choice set when none of each option better than the others in all aspects. Context effect signifies that when evaluating a focal option, individuals take into consideration characteristics of other comparative alternatives rather than only the features of that focal alternative, complicating the decision-making process. The compromise effect and attraction effect (known together as context effect) explain the underlying motivations that cause consumers to choose the middle option and introduce an inferior option to make the originally dominated option more preferable. But past research on this domain has predominantly used an easy-to-count choice scenario (refers to the ease of using individual’s math skill on comparative attributes in the choice task) which is not ideally existed in real world situation. In real world purchasing situations, most of the time consumers become confused by a variety of products presented with irregular pricing, packaging or attributes which are apparently difficult to compare by math skill. This paper aim to examine “When the level of difficulty changed while processing the comparative task on the context of a choice set, how does this influence the resultant occurrence of context effect?” Results from four experiments demonstrate that both compromise and attraction effects decreased when the choice task become more difficult.     

On the temporal dynamics of language-mediated vision and vision-mediated language

Recent converging evidence suggests that language and vision interact immediately in non-trivial ways, although the exact nature of this interaction is still unclear. Not only does linguistic information influence visual perception in real-time, but visual information also influences language comprehension in real-time. For example, in visual search tasks, incremental spoken delivery of the target features (e.g., “Is there a red vertical?”) can increase the efficiency of conjunction search because only one feature is heard at a time. Moreover, in spoken word recognition tasks, the visual presence of an object whose name is similar to the word being spoken (e.g., a candle present when instructed to “pick up the candy”) can alter the process of comprehension. Dense sampling methods, such as eye-tracking and reach-tracking, richly illustrate the nature of this interaction, providing a semi-continuous measure of the temporal dynamics of individual behavioral responses. We review a variety of studies that demonstrate how these methods are particularly promising in further elucidating the dynamic competition that takes place between underlying linguistic and visual representations in multimodal contexts, and we conclude with a discussion of the consequences that these findings have for theories of embodied cognition.     

Bootstrap standard error and confidence intervals for the correlations corrected for indirect range restriction

The standard Pearson correlation coefficient, r, is a biased estimator of the population correlation coefficient, ρ(XY) , when predictor X and criterion Y are indirectly range-restricted by a third variable Z (or S). Two correction algorithms, Thorndike's (1949) Case III, and Schmidt, Oh, and Le's (2006) Case IV, have been proposed to correct for the bias. However, to our knowledge, the two algorithms did not provide a procedure to estimate the associated standard error and confidence intervals. This paper suggests using the bootstrap procedure as an alternative. Two Monte Carlo simulations were conducted to systematically evaluate the empirical performance of the proposed bootstrap procedure. The results indicated that the bootstrap standard error and confidence intervals were generally accurate across simulation conditions (e.g., selection ratio, sample size). The proposed bootstrap procedure can provide a useful alternative for the estimation of the standard error and confidence intervals for the correlation corrected for indirect range restriction.     

Exposing operations of power in supervisory relationships

Through a poststructural lens, we examine how power may show itself in relationships between supervisees and supervisors, producing both helpful and harmful effects. Drawing from our own experiences, as well as conversations with other members of our supervisory group, we demonstrate how privileged discourses around professional status, gender, and race may bring about difficulties including a sense of doubt, worry, inadequacy, and a fear of speaking up. We also illustrate how these difficulties can be addressed in a manner that may lessen their influence, while increasing supervisees' sense of agency.     

Asian American college students' suicide ideation: a mixed-methods study

The purpose of this mixed-methods study was to explore the phenomenon of suicide ideation among 293 Asian American college students. Guided by T. Joiner's (2005) interpersonal-psychological theory of suicidal behavior, the authors examined the relationships among perceived burdensomeness, thwarted belongingness, self-construals, and suicide ideation. Compared with thwarted belongingness, perceived burdensomeness was a more robust predictor of suicide ideation. However, thwarted belongingness moderated the positive association between perceived burdensomeness and suicide ideation. Furthermore, interdependent self-construal and independent self-construal both weakened the link between perceived burdensomeness and suicide ideation and between thwarted belongingness and suicide ideation. The authors also conducted a qualitative analysis of participants' open-ended responses about their perceptions of why Asian American college students might consider suicide. The authors identified a core phenomenon of unfulfilled expectations as well as 2 broad themes related to this core phenomenon: unfulfilled intrapersonal expectations and unfulfilled interpersonal expectations, comprising the subthemes of (a) family, (b) relationship, (c) cultural differences, and (d) racism. These findings are discussed in terms of implications for suicide-related clinical interventions and primary prevention efforts among Asian American college students.
