Hard to decide? The effect of imagery perspective and construal level on decision difficulty

This research designed three experiments to investigate the mechanism of how imagery perspective influences decision difficulty, which increases consumers' willingness to postpone making choices based on the construal level. Studies 1, 2, and 3 demonstrated that imagining from the actor's perspective lowers one's construal level, and thus leads to greater decision difficulty and willingness to postpone making choices. In comparison, those taking the observer perspective represent things at higher construal levels and have less difficulty making decisions or willingness to postpone making choices. Moreover, the derived results showed the need for cognition to moderate the relationship between imagery perspective and construal level. The findings herein extended the physical buying situation to online consumption, providing implications for marketers to further explore consumer behavior.     

Does adaptive testing violate local independence?

Item response theory posits local independence, or conditional independence of item responses given item parameters and examinee proficiency parameters. The usual definition of local independence, however, addresses the context of fixed tests, and initially appears to yield incorrect response-pattern probabilities in the context of adaptive testing. The paradox is resolved by introducing additional notation to deal with the item selection mechanism.We are grateful to Charlie Lewis, Ming-Mei Wang, and Pao-Kuei Wu for discussions on this topic, and to the Editor, the reviewers, and Howard Wainer for helpful comments on an earlier version of the paper.

Structural Priming as Implicit Learning: A Comparison of Models of Sentence Production

Structural priming reflects a tendency to generalize recently spoken or heard syntactic structures to different utterances. We propose that it is a form of implicit learning. To explore this hypothesis, we developed and tested a connectionist model of language production that incorporated mechanisms previously used to simulate implicit learning. In the model, the mechanism that learned to produce structured sequences of phrases from messages also exhibited structural priming. The ability of the model to account for structural priming depended on representational assumptions about the nature of messages and the relationship between comprehension and production. Modeling experiments showed that comprehension-based representations were important for the model's generalizations in production and that nonatomic message representations allowed a better fit to existing data on structural priming than traditional thematic-role representations.     

Steroidal modulation of scent investigation and marking behaviors in male and female ferrets (Mustela putorius furo)

Gonadectomized male and female ferrets (Mustela putorius furo) given either testosterone propionate (TP) or oil vehicle preferred to investigate the side of a test cage previously soiled by a breeding male or female as opposed to a clean side. Male and female ferrets receiving TP showed more urogenital wiping than oil-treated animals in either side of the test cage. In a 2nd experiment, ferrets treated sequentially with TP, oil, and estradiol benzoate (EB) were given simultaneous access to sides of a test cage previously soiled by either a breeding female or male. Either EB or TP treatment of females and TP treatment of males facilitated the investigation of odors of opposite-sex ferrets. Females given TP and males given either TP or EB showed increased urogenital wiping in both sides of the test cage. Sex steroids modulate scent investigation and marking in adult ferrets in a sexually differentiated fashion.     

Imagining Garage Start-Ups: Interactive Effects of Imaginative Capacities on Entrepreneurial Intention

This article describes a structural examination of the interaction among different imaginative capacities and the entrepreneurial intention of electrical and computer engineering students. Two studies were combined to confirm the factor structure of survey items and test the hypothesised interaction model. The results indicated that imaginative capacity has 3 dimensions: conceiving, initiating, and transforming, whereas entrepreneurial intention comprises 2 factors: conviction and preparation. In addition, the results indicated that initiating imagination strongly affected entrepreneurial conviction and preparation; conceiving imagination positively predicted entrepreneurial conviction, whereas transforming imagination negatively predicted entrepreneurial preparation. The results also indicated that students possessing high, as well as those possessing low, conceiving and transforming imaginations demonstrated a high level of entrepreneurial preparation. In addition, an increase in transforming imagination increases the preparation of students possessing low initiating imagination and reduces the preparation of students possessing high initiating imagination. For developing a novel approach to conduct research on entrepreneurial intention and for discussing the practical implications of the findings, this study explicates alternative methods of cultivating students, promoting their interests, and enabling entrepreneurial behaviour in them by stimulating their imaginative capacities.     

Adult Learners’ Informal Learning Experiences in Formal Education Setting

Schools typically ignore an enormous part of students’ learning, i.e. informal learning. Such informal processes include intentional, incidental, and tacit learning and tend to be unnoticed because of their taken-for-granted nature. By conducting in-depth interviews with 15 students, two teachers, and two program coordinators of an adult education program, this study examines informal learning outcomes, processes, and personal informal learning experiences within formal education. The study aimed to reveal the interaction between formal and informal learning as well as the respondents’ experiences in this matter. Respondents report a diverse array of informal learning results. Respondents describe informal learning to occur through self-directed learning projects, daily conversations and experiences, and the program’s informal and hidden curriculum. According to respondents, informal learning has the potential to enrich and complement formal learning. Moreover, the findings point to potential personal, educational, and societal benefits of revealing informal learning within formal education. Implications for practice and future research are discussed.     

Association of Depressive Symptomatology and Elder Mistreatment in a U.S. Chinese Population: Findings From a Community-Based Participatory Research Study

Elder mistreatment (EM) is associated with increased morbidity and mortality. The objective of this study is to examine the association between depressive symptoms and EM in a U.S. Chinese population. A community-based participatory research approach was implemented to partner with the Chicago Chinatown population. Self-reported EM was assessed using a modified Vulnerability to Abuse Screening Scale instrument. Depressive symptomatology was assessed using the short form Geriatric Depression Scale. Exact logistic regression was used to assess these associations. Of the 78 participants, mean age was 74.8 (SD = 7.8) years and 52.6% were women. EM was reported in 20.5% of participants. After adjusting for potential confounding factors, higher numbers of depressive symptoms were independently associated with increased risk of EM (Exact OR, 1.99, 95% CI [1.23, 3.41]). Interaction terms analyses suggest that higher educational levels might buffer the risk of EM associated with depressive symptoms. Longitudinal studies are needed to confirm these findings in this U.S. Chinese population.
