Space aliens and nonwords: stimuli for investigating the learning of novel word-meaning pairs.

We describe a set of pictorial and auditory stimuli that we have developed for use in word learning tasks in which the participant learns pairings of novel auditory sound patterns (names) with pictorial depictions of novel objects (referents). The pictorial referents are drawings of "space aliens," consisting of images that are variants of 144 different aliens. The auditory names are possible nonwords of English; the stimulus set consists of over 2,500 nonword stimuli recorded in a single voice, with controlled onsets, varying from one to seven syllables in length. The pictorial and nonword stimuli can also serve as independent stimulus sets for purposes other than word learning.

话题兴趣与文本阅读眼动特征的研究

以大学生为被试,用ASL504型眼动仪,探讨话题兴趣对文本阅读过程眼动特征和文本阅读理解的影响。结果表明：(1)话题兴趣促进深层理解,而不能促进表层理解。(2)话题兴趣主要与阅读时间和注视点数相关联,而与阅读效率无关。(3)文本阅读过程中,阅读时间、注视点数两项眼动指标存在显著的性别差异。     

Torque levels, subjective discomfort, and muscle activity associated with four commercially available screwdrivers under static and dynamic work conditions

This study evaluated screwdrivers with different handle designs and blade lengths. 10 men and 10 women voluntarily participated. A repeated-measures experiment design was employed. The three independent factors were sex of user, handle (four types), and blade length (130, 170, and 210 mm). The dependent measures were the maximum supination torque under a static task and the %MVC of EMG responses in biceps brachii and flexor digitorum, and a discomfort rating for the upper extremity under the dynamic task. Analysis showed that the in-line screwdriver with the combined characteristics of large handle diameter (3.8-4.1 cm), smooth rubber covering handle surface, triangular (or circular) shape, and adequate handle length (11 cm) had the greatest supination torque and a smaller discomfort rating than the screwdriver with the pistol-grip handle. Blade length was not significantly related to any dependent measure.     

Age,sex, education,religion, and perception of tattoos

Tattooing has become more acceptable in the mainstream American culture in recent years. Based on a survey with face-to-face interviews of 335 nontattooed adults randomly selected from a city with a population of 444,000, this study explored the relationship of individuals' demographic variables, attitudes toward religion, and their perceptions of tattoos. The hierarchical multiple regression analysis showed that age and attitude toward religion were associated with individuals' perception of tattoos.     

Postural muscle responses following changing balance threats in young, stable older, and unstable older adults

The authors determined the postural muscle response to support surface perturbations, in relation to aging and level of stability of 16 young adults and 32 older adults who were classified into stable (SOA) and unstable (UOA) groups on the basis of their functional balance abilities. Forward and backward support surface translations of various amplitudes and velocities were used so that postural responses of the standing adults could be elicited. The thigh and leg postural muscle responses were recorded with surface electromyography (EMG). The older groups had significantly longer onset latency in the anterior postural muscles, smaller integrated EMG in the posterior muscles, and greater extent of integrated EMG attenuation over time. The UOA showed longer onset latency in the gastrocnemius following slow backward perturbation and used a greater percentage of the functional capacity of the gastrocnemius muscle than the SOA did. Those findings indicate that the SOA and UOA had limited ability to adapt to changing balance threats; the UOA were more limited than the SOA. When designing balance training programs, therefore, therapists should consider the adult's level of functional stability.     

An exploration of Taiwanese adolescents' impulsive buying tendency

The purpose of this study was to examine via a questionnaire the personal characteristics and impulsive buying tendencies of 15- to 19-year-old Taiwanese adolescents. Results indicated that the impulsive buying was significantly associated with gender, age, and amount of pocket money available. Females indicated more impulsive buying than did males, and gradually increased with age. Impulsive buying significantly increased with the increase in the amount of pocket money available. Possible extensions of the research in this area are offered.     

Stereotype content model explains prejudice for an envied outgroup: Scale of anti-Asian American Stereotypes

The Stereotype Content Model hypothesizes anti-Asian American stereotypes differentiating two dimensions: (excessive) competence and (deficient) sociability. The Scale of Anti-Asian American Stereotypes (SAAAS) shows this envious mixed prejudice in six studies. Study 1 began with 131 racial attitude items. Studies 2 and 3 tested 684 respondents on a focused 25-item version. Studies 4 and 5 tested the final 25-item SAAAS on 222 respondents at three campuses; scores predicted outgroup friendships, cultural experiences, and (over)estimated campus presence. Study 6 showed that allegedly low sociability, rather than excessively high competence, drives rejection of Asian Americans, consistent with system justification theory. The SAAAS demonstrates mixed, envious anti-Asian American prejudice, contrasting with more-often-studied contemptuous racial prejudices (i.e., against Blacks).     

Thematic relations in adults' concepts

Concepts can be organized by their members' similarities, forming a kind (e.g., animal), or by their external relations within scenes or events (e.g., cake and candles). This latter type of relation, known as the thematic relation, is frequently found to be the basis of children's but not adults' classification. However, 10 experiments found that when thematic relations are meaningful and salient, they have significant influence on adults' category construction (sorting), inductive reasoning, and verification of category membership. The authors conclude that concepts function closely with knowledge of scenes and events and that this knowledge has a role in adults' conceptual representations.     

Sex differences in intercultural communication apprehension,ethnocentrism, and intercultural willingness to communicate

Communication predispositions influence interactions between individuals from different cultures. Three such predispositions have been found to affect behavior in intercultural contexts: Apprehension about intercultural communication, ethnocentrism, and intercultural willingness to communicate. This study examined differences between men (n = 130) and women (n = 175) on those three predispositions. The analysis showed that men reported experiencing higher apprehension about intercultural communication, being more ethnocentric than women, and being less willing to communicate interculturally than women. Implications of these findings are discussed.     

Testing the bidirectional relationship between belief in COVID-19 conspiracy theories and psychological distress: A five-wave longitudinal study

Previous studies have primarily focused on understanding why people believe conspiracy theories, especially during societal crises (e.g., the COVID-19 pandemic). The investigation of how such conspiracy beliefs would influence people's mental well-being has just begun recently. The present research aims to address this crucial question by testing the relationships between psychological distress and COVID-19 conspiracy beliefs with a five-wave longitudinal study. On the one hand, COVID-19 conspiracy beliefs could be more appealing to people with heightened distress, as these theories apparently help people to make sense of the uncertainty and life-threatening disease outbreak. On the other hand, conspiracy theories could be a source of existential threat and thus, would induce rather than reduce psychological distress. We tested these possibilities empirically by a series of cross-lagged model analyses. Using the random intercept cross-lagged panel model analysis, we only found a between-person association but not a cross-lagged within-person relationship between the two. COVID-19 conspiracy beliefs was predicted by being more politically conservative. These findings were further corroborated by the supplementary latent growth curve analyses. Overall, our findings suggest that conspiracy beliefs may not induce or reduce psychological distress in the context of COVID-19.
