Is the Interdependent Self More Sensitive to Question Context Than the Independent Self? Self-Construal and the Observation of Conversational Norms

Question answering requires close attention to the common ground to determine what the questioner wants to know. Because attentiveness to others is more likely to be a self-defining goal when the self is thought of as interdependent with others rather than independent of others, we predicted that self-construal influences attentiveness to the common ground. In Experiment 1, participants' temporary self-construal was manipulated through a priming technique. As predicted, interdependence-primed participants were more likely than independence-primed participants to take the recipient's knowledge into account and avoided providing redundant information in a self-administered questionnaire. Drawing on chronic differences in self-construal, Experiment 2 replicated these findings with participants from independent (Germany) and interdependent (China) cultures. Throughout, participants' differential attentiveness to the common ground resulted in differential question order effects, raising important methodological issues for cross-cultural research.     

Discrepancy-plus-search processes in prospective memory retrieval

In the present study, we investigated the processes underlying prospective memory (PM) retrieval, focusing specifically on two possible spontaneous processes: discrepancy-plus-search and familiarity. Discrepancy was elicited by orthogonally manipulating the processing difficulties of the PM targets and the nontargets. Participants performed a PM task while solving anagrams with two levels of difficulty (easy or difficult). Assuming that the ease of processing easy anagrams would heighten a sense of familiarity, the familiarity view predicted better PM performance with easy anagrams as the PM targets. In contrast, the discrepancy-plus-search view predicted higher PM performance for the PM targets that were anagrams whose difficulty level mismatched that of the surrounding nontargets, as compared to PM targets whose difficulty matched that of the surrounding nontargets. This prediction was based on the idea that mismatching rather than matching difficulty levels would create discrepancy, thereby signaling significance for the target. Participants were more likely to perform the PM task for PM targets that were discrepant, supporting the discrepancy-plus-search view.     

The state of order in Fe–Al studied by precession electron diffraction

Precession electron diffraction (PED) has been carried out on a fully ordered Fe–40at.%Al solid solution in order to explore its suitability for determining the state of order. The integrated intensity ratio of a superlattice reflection with respect to a fundamental reflection was measured as a function of the sample thickness and the results are well fitted by dynamical simulations. It is proposed that, in addition to conventional X-ray diffraction, PED may provide access to the state of order at microscopic and nanoscopic scales.     

Contextualization in Perspective

In this article, we examine the hypothesis that problem comprehension and computational processes interact during the solving of an arithmetic word problem. Two experiments tested subjects on a series of addition and subtraction word problems, the content of which varied on the basis of problem type and on the magnitude of the numbers involved (problem size). Performance data are presented and analyzed in terms of solution reaction times and error patterns. Results confirmed the main effects of problem size and problem type as factors determining reaction times but failed to show any significant interaction between the two factors. These results suggest that the cognitive processes involved in understanding an arithmetic word problem and in performing the required computations are best explained by a serial processing model. The absence of an interaction between problem comprehension and computational processes questions the notion that automatized retrieval facilitates problem solving and assertions suggesting that increasing computational requirements can interfere with problem-solving performance.     

Islamic Doctrinal Orthodoxy and Religious Orientations: Scale Development and Validation

A measure of Islamic doctrinal orthodoxy was developed, and its relation to personal religious activities was examined. This study also applied the concept of extrinsic, intrinsic, and quest religiosity to Islamic faith as it investigated the structural validity and internal consistency of Islamic versions of the religious orientation scales. A sample of 381 students was taken from three universities in Indonesia. Notably, the scales were found to be psychometrically adequate and their doctrinal orthodoxy and intrinsic and extrinsic religiosity scores significantly related to personal practice of religious activities. A subsequent analysis also revealed that, for Muslims, doctrinal beliefs are largely independent of extrinsic, intrinsic, and quest religiosity and that the three forms of religiosity are three autonomous but continuous dimensions of personal religiosity.     

Evidence for a detrimental relationship between hypertension history, prospective memory, and prefrontal cortex white matter in cognitively normal older adults

Hypertension affects many older adults and is associated with impaired neural and cognitive functioning. We investigated whether a history of hypertension was associated with impairments to prospective memory, which refers to the ability to remember to perform delayed intentions, such as remembering to take medication. Thirty-two cognitively normal older adult participants with or without a history of hypertension (self-reported) performed two laboratory prospective memory tasks, one that relied more strongly on executive control (nonfocal prospective memory) and one that relied more strongly on spontaneous memory retrieval processes (focal prospective memory). We observed hypertension-related impairments for nonfocal, but not focal, prospective memory. To complement our behavioral approach, we conducted a retrospective analysis of available structural magnetic resonance imaging data. Lower white matter volume estimates in the anterior prefrontal cortex were associated with lower nonfocal prospective memory and with a history of hypertension. A history of hypertension may be associated with worsened executive control and lower prefrontal white matter volume. The translational implication is that individuals who must remember to take antihypertensive medications and to monitor their blood pressure at home may be impaired in the executive control process that helps to support these prospective memory behaviors.

The efficacy of conjoint behavioral consultation on parents and children in the home setting: Results of a randomized controlled trial

The present study is a large-scale randomized trial testing the effects of a family–school partnership model (i.e., Conjoint Behavioral Consultation, CBC) for promoting behavioral competence and decreasing problem behaviors of children identified by their teachers as disruptive. CBC is a structured approach to problem-solving that involves consultants, parents, and teachers. The effects of CBC on family variables that are commonly associated with important outcomes among school-aged children (i.e., family involvement and parent competence in problem solving), as well as child outcomes at home, were evaluated. Participants were 207 children with disruptive behaviors from 91 classrooms in 21 schools in kindergarten through grade 3 and their parents and teachers. Results indicated that there were significantly different increases in home–school communication and parent competence in problem solving for participants in the CBC relative to control group. Likewise, compared to children in the control group, children in the CBC group showed significantly greater decreases in arguing, defiance, noncompliance, and tantrums. The degree of family risk moderated parents' competence in problem solving and children's total problem behaviors, teasing, and tantrums.     

The effects of culture and self-construal on responses to threatening health information

Objective: The current studies examined if cultural and self-construal differences in self-enhancement extended to defensive responses to health threats.

Design: Responses to fictitious medical diagnoses were compared between Asian-Americans and European-North Americans in Experiment 1 and between Canadians primed with an interdependent versus an independent self-construal in Experiment 3. In Experiment 2, the responses of Chinese and Canadians who were either heavy or light soft drink consumers were assessed after reading an article linking soft drink consumption to insulin resistance.

Main outcome measure: The primary-dependent measure reflected participants’ defensiveness about threatening versus nonthreatening health information.

Results: In Experiment 1, all participants responded more defensively to an unfavourable than a favourable diagnosis; however, Asian-Americans responded less defensively than did European-North Americans. In Experiment 2, all high soft drink consumers were less convinced by the threatening information than were low soft drink consumers; however, among high consumers, Chinese changed their self-reported consumption levels less than did European-Canadians. In Experiment 3, interdependence-primed participants responded less defensively to an unfavourable diagnosis than did independence-primed participants.

Conclusion: Defensive reactions to threatening health information were found consistently; however, self-enhancement was more pronounced in individuals with Western cultural backgrounds or independent self-construals.     

Cooling-rate-dependent microstructure and mechanical properties of a CuZrAlAg alloy

A Cu₃₆Zr₄₈Al₈Ag₈ alloy rod with a diameter of 10 mm was fabricated using a copper-mould suction casting method. Structural characterization revealed that the rod has different microstructures along the casting direction, including a complete amorphous structure and an amorphous/crystalline composite structure with different amount of B2 CuZr phase. Nanoindentation tests showed that the hardness and the elastic modulus of the crystalline phase are lower than those of the amorphous matrix. The hardness and the elastic modulus of the amorphous matrix decrease with decreasing crystalline proportion of the alloy, while the Vickers hardness of the alloy increases with a reduction in the crystalline proportion.
