Effects of repetition and response deadline on item recognition in young and older adults

In the present study, we examined the joint effects of aging, repetition, and response deadline in a plurality discrimination task. Young and older adults studied lists of unrelated singular and plural nouns, with half presented once (weak items) and half presented five times (strong items). Test lists contained old (same) nouns, plurality-reversed nouns (changed lures), and unstudied nouns (new lures), and the participants were asked to respond old only to same items. In Experiment 1, the participants were tested with both short and long deadlines. In Experiment 2, the tests were unpaced. In both experiments, repetition increased hit rates for young and older adults. Young adults tested with a long deadline or no deadline showed invariant (Experiment 1) or reduced (Experiment 2) false alarms to changed lures when the nouns were studied more often. Young adults tested with a short deadline and older adults tested with both long and short deadlines had increased false alarm rates for strong changed lures; without time pressure to respond, older adults did not have a significant increase in false alarms for changed lures. Implications of these results for theories of cognitive aging are explored.     

Dual-process models of associative recognition in young and older adults: evidence from receiver operating characteristics

In 3 experiments, young and older adults studied lists of unrelated word pairs and were given confidence-rated item and associative recognition tests. Several different models of recognition were fit to the confidence-rating data using techniques described by S. Macho (2002, 2004). Concordant with previous findings, item recognition data were best fit by an unequal-variance signal detection theory model for both young and older adults. For both age groups, associative recognition performance was best explained by models incorporating both recollection and familiarity components. Examination of parameter estimates supported the conclusion that recollection is reduced in old age, but inferences about age differences in familiarity were highly model dependent. Implications for dual-process models of memory in old age are discussed.     

Language transfer and blocking in second language vocabulary learning

The influence of different vocabulary instructional techniques upon the acquisition of different language words was examined in two experiments. In Experiment 1, comparisons were made between the learning of Chinese and French words employing both paired-associate presentations and spacing procedures. The results supported the view that language transfer affects the acquisition of second language words, with more French words being learned than Chinese words. The superiority of the spacing procedure over the paired-associate presentation found in these results suggested that the spacing method diminished the adverse effects of blocking and thus enhanced learning. However, no significant interaction between the teaching procedures and different language words was detected. That is, under the spacing procedure, greater improvement in learning of Chinese words was not found. The experiment was thus modified by substituting the spacing procedure with aural feedback in Experiment 2. In this experiment, a significant interaction between these two factors was detected. That is, the recall for French was more than Chinese in the paired-associate condition, however, under the aural feedback, performance in Chinese was statistically equivalent to that in French. Hence, these findings may contradict the prediction of language transfer. It appears that the phenomenon of language transfer may be far less important in vocabulary learning than the use of a method of instruction which neutralises the negative effects of blocking.     

Quasi-reinforcement: control of responding by a percentage-reinforcement schedule

When a variable-interval schedule of reinforcement was segmented into small fixed-interval components, with reinforcements following some components and brief blackouts following the others, rate of responding doubled and a positively accelerated pattern within each component was obtained. Presented according to this percentage reinforcement paradigm, the blackouts approximated the functions of a food reinforcer. These effects occurred only when the behavior sequence required to produce reinforcement was identical to that required to produce blackout. The quasi-reinforcing effects of these blackout stimuli suggest that a neutral stimulus need not occasion or accompany a primary reinforcer to acquire reinforcing properties.     

Design, Development, and Evaluation of a Second Generation Interactive Simulator for Engineering Ethics Education (SEEE2)

This paper describes a second generation Simulator for Engineering Ethics Education. Details describing the first generation activities of this overall effort are published in Chung and Alfred (Sci Eng Ethics 15:189?C199, 2009). The second generation research effort represents a major development in the interactive simulator educational approach. As with the first generation effort, the simulator places students in first person perspective scenarios involving different types of ethical situations. Students must still gather data, assess the situation, and make decisions. The approach still requires students to develop their own ability to identify and respond to ethical engineering situations. However, were as, the generation one effort involved the use of a dogmatic model based on National Society of Professional Engineers?? Code of Ethics, the new generation two model is based on a mathematical model of the actual experiences of engineers involved in ethical situations. This approach also allows the use of feedback in the form of decision effectiveness and professional career impact. Statistical comparisons indicate a 59 percent increase in overall knowledge and a 19 percent improvement in teaching effectiveness over an Internet Engineering Ethics resource based approach.     

The contribution of self‐deceptive enhancement to display rules in the United States and Japan

Socially desirable responding was tested as a mediator of American and Japanese college student differences in display rules. Americans endorsed the expression of anger, contempt, disgust, fear, happiness, and surprise more than the Japanese. Americans also exhibited more self‐deceptive enhancement than the Japanese, and self‐deceptive enhancement partially mediated country differences on the endorsement of anger, disgust, happiness, and surprise, but not contempt and fear. These findings highlight the role of self‐deceptive enhancement in contributing to expressive display rules and support the point of view that socially desirable responding is a reflection of one's personality and culture rather than a statistical nuisance.     

Practical recommendations for considering culture,race, and ethnicity in personality psychology

Personality science is the study of the individual. It aims to understand what makes people similar to others, different from some, and unique to themselves. However, there is room for research in personality to more thoughtfully consider culture, race, and ethnicity in order to better understand individual differences in people’s patterns of thinking, feeling, and behaving. High impact personality journals rarely include such factors into the interpretation of results, and cross-cultural and ethnic minority publications are limited within the discipline. This article offers a brief, non-exhaustive overview of how culture, race, and ethnicity are examined in relation to personality, showing that: (1) social structures continue to be neglected in the research, (2) we can learn from research being conducted in neighboring areas, and (3) valuable work is already being done within personality psychology. We offer recommendations that emphasize community based participatory research methods, combined etic-emic approaches, and contextualizing research findings to improve the consideration of culture, race, and ethnicity in personality research.     

A Reflection on the Growth and Decline of the Korean Protestant Church

This article examines the reasons for the growth and decline of the Korean Protestant Church during the following five periods:

• In the early period of settlement (1884–1909), growth originated from the emancipation motif, modern values, the Christian's moral life, the Revival experience, Bible study, and the prayer culture. The Korean church did not polarize evangelism and social action.
• During Japanese domination (1910–1945), growth came from the respect of the people toward the church. The church served the nation, consoled and healed the minds of the people, and gave brave witness of their faith in God. However, political persecution, economic devastation, socialist influences, and finally the coercion of the Shinto shrine worship to the church blocked church growth.
• During the recovery time (1945–1960), the social anomie after the nation's liberation and the Korean War ironically became a seedbed for church growth. However, the church improperly made her image pro‐government and pro‐America.
• During the time of industrialization and urbanization (1960–1995), Korean Protestantism achieved great growth and the highest percentage. Most of the Korean Protestant churches in cities, taking advantage of the mass rural–city migration, were actively involved in evangelism and church planting. University mission organizations and military missions were most active. Yet, they did not do well in terms of holistic evangelism. On the other hand, the National Council of Churches in Korea (NCCK), the Urban Rural Mission (URM,) the minjung churches and others carried out social mission work.
• After the time of urbanization (1995–2005), church membership began to decrease. The Protestant church‐planting policy in city areas became inappropriate. In addition, the church's political conservatism fell out of favour with the young generation.

     

Development of a simple pressure and heat stimulator for intra- and interdigit functional magnetic resonance imaging

For this study, we developed a simple pressure and heat stimulator that can quantitatively control pressure and provide heat stimulation to intra- and interdigit areas. The developed stimulator consists of a control unit, drive units, and tactors. The control unit controls the stimulation parameters, such as stimulation types, intensity, time, and channel, and transmits a created signal of stimulation to the drive units. The drive units operate pressure and heat tactors in response to commands from the control unit. The pressure and heat tactors can display various stimulation intensities quantitatively, apply stimulation continuously, and adjust the stimulation areas. Additionally, they can easily be attached to and detached from the digits. The developed pressure and heat stimulator is small in total size, easy to install, and inexpensive to manufacture. The new stimulator operated stably in a magnetic resonance imaging (MRI) environment without affecting the obtained images. A preliminary functional magnetic resonance imaging (fMRI) experiment confirmed that differences in activation of somatosensory areas were induced from the pressure and heat stimulation. The developed pressure and heat stimulator is expected to be utilized for future intra- and interdigit fMRI studies on pressure and heat stimulation.
