Overhearing a language during childhood

Despite its significance for understanding of language acquisition, the role of childhood language experience has been examined only in linguistic deprivation studies focusing on what cannot be learned readily beyond childhood. This study focused instead on long-term effects of what can be learned best during childhood. Our findings revealed that adults learning a language speak with a more nativelike accent if they overheard the language regularly during childhood than if they did not. These findings have important implications for understanding of language-learning mechanisms and heritage-language acquisition.     

Holding on to childhood language memory

While early language experience seems crucial for mastering phonology, it remains unclear whether there are lasting benefits of speaking a language regularly during childhood if the quantity and quality of speaking drop dramatically after childhood. This study explored the accessibility of early childhood language memory. Specifically, it compared perception and production of Korean speech sounds by childhood speakers who had spoken Korean regularly for a few years during childhood to those of two other groups: (1) childhood hearers who had heard Korean regularly during childhood but had spoken Korean minimally, if at all; and (2) novice learners. All three groups were enrolled in first-year college Korean language classes. Childhood speakers were also compared to native speakers of Korean to see how native-like they were. The results revealed measurable long-term benefits of childhood speaking experience, underscoring the importance of early language experience, even if such experience diminishes dramatically beyond childhood.     

An electrode hookup for eyelid conditioning

A method for recording eyelid CRs, using skin electrodes rather than the usual mechanical connection to the S’s eyelid, is described. Data are presented to show the comparability of the two recording systems.     

True versus strategic fairness in a common resource dilemma: Evidence from the dual‐process perspective

Common resource dilemmas involve collectively coordinating individual choices to promote group efficiency. Equal division represents one of the most important coordination rules. Previous research suggests that individuals follow the equality rule for different reasons. Some individuals behave cooperatively out of their concern for other's welfare, whereas some individuals cooperate strategically to enhance personal gains. Building on the dual‐process perspective, the authors aim to differentiate strategic fairness from true fairness in solving a resource dilemma. In four experiments, the effect of cognitive processing manipulations on individual harvesting behavior in a one‐shot resource dilemma was tested against participants with different social values. Results consistently showed that prosocials, who value joint outcome and equality, requested significantly less money than did proselfs, who value personal gain. More importantly, prosocials in the intuition and deliberation conditions request similar amounts, whereas proselfs in the intuition condition request more money than those in the deliberation condition. The results were further validated by a follow‐up meta‐analysis based on the four experiments. The implications of the dual‐process perspective for social coordination research are discussed.     

Seeing the forest and not the trees: When impact uncertainty heightens causal complexity

This study attempts to isolate the effects of experiencing uncertainty on people's cognitive processes. I argue that people can believe that their actions affect the outcome (i.e. outcome control), but still face uncertainty regarding the extent to which actions will make a difference (i.e. impact uncertainty). To this end, I introduce a novel experimental paradigm which isolates the effects of impact uncertainty from outcome control. The findings revealed that after experiencing impact uncertainty, participants demonstrated greater causal complexity (i.e. more likely to make situational attributions and judge outcomes as having a “ripple effect”), but did not make fewer effort attributions for the outcomes. These findings demonstrate how the experience of impact uncertainty can affect cognitive processing, without compromising outcome control. Implications of these findings for developing more nuanced theories on control and uncertainty are discussed.     

Folkbiology meets microbiology: a study of conceptual and behavioral change

Health education can offer a valuable window onto conceptual and behavioral change. In Study 1, we mapped out 3rd-grade Chinese children’s beliefs about causes of colds and flu and ways they can be prevented. We also explored older adults’ beliefs as a possible source of the children’s ideas. In Study 2, we gave 3rd- and 4th-grade Chinese children either a conventional cold/flu education program or an experimental “Think Biology” program that focused on a biological causal mechanism for cold/flu transmission. The “Think Biology” program led children to reason about cold/flu causation and prevention more scientifically than the conventional program, and their reasoning abilities dovetailed with their mastery of the causal mechanism. Study 3, a modified replication of Study 2, found useful behavioral change as well as conceptual change among children who received the “Think Biology” program and documented coherence among knowledge enrichment, conceptual change, and behavioral change.     

Predicting the psychological health of older adults: Interaction of age-based rejection sensitivity and discriminative facility

We hypothesize that older adults who anxiously expect, readily perceive, and intensely react to social rejection because of their old age (i.e., have high age-based rejection sensitivity) are vulnerable to depression and poor social functioning. We further hypothesize that the association between age-based rejection sensitivity and poor psychological health would be attenuated among older adults who possess adequate cognitive coping ability—they can discern and respond discriminatively to subtle variations in situational demands (i.e., have high discriminative facility). Based on the results of a focus group study, we constructed an age-based rejection sensitivity measure, which predicts greater depression, poorer social functioning, greater loneliness, and lower life satisfaction among individuals in late adulthood. As hypothesized, the relationship between age-based rejection sensitivity and poor psychological health was weaker among older adults with high (vs. low) discriminative facility.     

Effects of Protocol of Play and Social Orientation on Behavior in Sequential Resource Dilemmas

We report results of an experiment in which we examined consumption behavior of groups of players sharing a common resource pool under four distinct protocols of play. Under thesimultaneousprotocol all subjects make their requests simultaneously. In the other three protocols, players make requests, one at a time, but with various types and levels of information about the process: In thesequentialprotocol, subjects make requests with complete information about their position in the sequence and full disclosure of previous requests; In thepositionalprotocol, requests are made with precise information on one's position in the sequence order, but without disclosing the requests of previous players; Finally, under thecumulativeprotocol, subject make requests with complete information regarding the total previous requests, but do not know their exact position in the sequence. We found a significant "position effect" in all three nonsimultaneous protocols: Mean individual requests and position in the sequence are negatively correlated, reflecting an "early mover advantage" and a "late mover handicap." The effect is weakest in the positional protocol, whereas the sequential and cumulative protocols are, practically, identical. We conclude that although position effects can be induced by temporal priority, they are primarily driven by differential patterns of information regarding the behavior of the other group members. Although the request pattern was consistent with predictions based on the subjects' social orientation, the differences were not quite as pronounced (and significant) as in the "regular" simultaneous dilemmas. On the other hand, we found that the subjects' requests in the simultaneous protocol were an accurate predictor of their behavior in the other protocols as well.     

Reduced specificity of autobiographical memory and depression: the role of executive control

It has been widely established that depressed mood states and clinical depression, as well as a range of other psychiatric disorders, are associated with a relative difficulty in accessing specific autobiographical information in response to emotion-related cue words on an Autobiographical Memory Test (AMT; J. M. G. Williams & K. Broadbent, 1986). In 8 studies the authors examined the extent to which this relationship is a function of impaired executive control associated with these mood states and clinical disorders. Studies 1-4 demonstrated that performance on the AMT is associated with performance on measures of executive control, independent of depressed mood. Furthermore, Study 1 showed that executive control (as measured by verbal fluency) mediated the relationship between both depressed mood and a clinical diagnosis of eating disorder and AMT performance. Using a stratified sample in Study 5, the authors confirmed the positive association between depressed mood and impaired performance on the AMT. Studies 6-8 involved experimental manipulations of the parameters of the AMT designed to further indicate that reduced executive control is to a significant extent driving the relationship between depressed mood and AMT performance. The potential role of executive control in accounting for other aspects of the AMT literature is discussed.     

Interactional justice and the fair process effect: The role of outcome uncertainty

This paper reconciles the inconsistent findings on the interactive effect of interactional justice and social comparison information on outcome evaluation. We distinguish two different effects of interactional justice and examine outcome uncertainty as a qualifying factor. Three hundred and fifty-seven undergraduates participated in a scenario experiment. It is found that, due to the functional quality effect, interactional justice significantly influences outcome evaluation, regardless of the social comparison information that is available, in situations of low outcome uncertainty. However, due to the fair process effect, interactional justice, as with procedural justice, interacts with social comparison information to influence outcome evaluation in situations of high outcome uncertainty. Implications for comparison referents and social comparison motives in social justice research are discussed.
