Affective auditory stimulus database: An expanded version of the International Affective Digitized Sounds (IADS-E)

Using appropriate stimuli to evoke emotions is especially important for researching emotion. Psychologists have provided several standardized affective stimulus databases—such as the International Affective Picture System (IAPS) and the Nencki Affective Picture System (NAPS) as visual stimulus databases, as well as the International Affective Digitized Sounds (IADS) and the Montreal Affective Voices as auditory stimulus databases for emotional experiments. However, considering the limitations of the existing auditory stimulus database studies, research using auditory stimuli is relatively limited compared with the studies using visual stimuli. First, the number of sample sounds is limited, making it difficult to equate across emotional conditions and semantic categories. Second, some artificially created materials (music or human voice) may fail to accurately drive the intended emotional processes. Our principal aim was to expand existing auditory affective sample database to sufficiently cover natural sounds. We asked 207 participants to rate 935 sounds (including the sounds from the IADS-2) using the Self-Assessment Manikin (SAM) and three basic-emotion rating scales. The results showed that emotions in sounds can be distinguished on the affective rating scales, and the stability of the evaluations of sounds revealed that we have successfully provided a larger corpus of natural, emotionally evocative auditory stimuli, covering a wide range of semantic categories. Our expanded, standardized sound sample database may promote a wide range of research in auditory systems and the possible interactions with other sensory modalities, encouraging direct reliable comparisons of outcomes from different researchers in the field of psychology.     

Area-Level Income Inequality and Individual Happiness: Evidence from Japan

In this study, we investigated how area-level income inequality is associated with an individual’s assessment of happiness, based on micro-level data sourced from nationwide surveys in Japan. It was confirmed from our analysis using logit models that individuals who live in areas of high income inequality tend to report themselves as being less happy, even after controlling for various individual and area-level factors. The association between inequality and happiness is modestly significant, regardless of the choice of covariates at an individual level, and stronger at a lower level of perceived happiness. Moreover, sensitivity to inequality differs substantially according to certain individual attributes. Among others, an important implication for social policy is that those with unstable occupational status are more sensitive to inequality. Given that these people tend to be less happy than others, this result indicates the risk that area-level inequality further reduces the well-being of those with unfavorable employment conditions.     

��Does Plagiarism Mean anything? LOL.�� Students�� Conceptions of Writing and Citing

This study focuses on the intersection of research ethics and academic writing, i.e. the use of sources, assignment of credit to the contributors in the research, and the dissemination of research findings. The study utilized a set of semi-structured and open-ended questions. The sample consisted of 269 undergraduate (BA) and graduate (MA) students at a U.S. university department of psychology including major and non-major students. The data showed that although an overwhelming number of the students’ examples related to ethical issues in citation dealt with plagiarism, a broad range of examples of other types of issues were also provided. Understandably, students tended to view the questions about both the assignment of credit to those involved in conducting the research and the dissemination of research findings from the research participant’s perspective, which is more familiar to them than the researcher perspective. In order to help the students to expand their notions beyond the immediate own experience to a broader understanding for the ethical principles that ought to guide a researcher in his or her work, it is desirable that students be provided with opportunities to participate in authentic research projects. With a deeper understanding of the students’ conceptions of ethics in research and academic writing, we can become more attuned to the common limitations and misconceptions that students harbor, and thus better equipped to support students in their learning process.     

A dissociation between the sense of familiarity and access to semantic information concerning familiar people

In the current study we examined the relationship between working memory capacity, inhibition/susceptibility to interference and fluid intelligence, measured by the Raven's Progressive Matrices (PM38), comparing groups of young (aged 18–35), young-old (aged 65–74), and old-old (aged 75–86) participants. Groups were administered two working memory tasks tapping into different mechanisms involved in working memory. The ability to control for irrelevant information was measured both considering memory errors (intrusion errors) in a working memory task and an index of susceptibility to interference obtained with a variant of the Brown-Peterson task. Regression analyses showed that the classical working memory measure was the most potent predictors of the Raven's score. Susceptibility to interference and intrusions errors contributed, but to a lower extent, to the Raven explained variance. These results confirm that working memory shares cognitive aspects with the fluid intelligence measure considered, whereas the role of inhibition to Raven scores is still in need of better evidence.     

Challenges of organizational learning: perpetuation of discrimination against employees with disabilities

This article examines why organizations struggle with learning how to prevent discrimination against their employees with disabilities. To explore this issue, qualitative archival data were collected and analyzed from 53 Americans with Disabilities Act (ADA) lawsuits filed against 44 organizations. Theoretical analysis of the qualitative data suggests that several organizationally based learning theories explain the difficulty organizations have with creating a disability-friendly work environment. These barriers to learning are embedded in complex defense mechanisms and discriminatory organizational routines. Furthermore, organizations have difficulties engaging in higher-order and vicarious learning. We conclude the article with examples of successful learning practices as they relate to barriers identified in the qualitative analysis.     

Coping Self-Efficacy as a Mediator of Distress Following a Natural Disaster

Social-cognitive theory and conservation-of-resources theory were utilized to understand individual differences in psychological response to natural disaster. Coping self-efficacy, lost resources, social support, and optimism were assessed along with demographic variables in predicting distress following Hurricane Opal. Participants included 67 residents of Okaloosa County, Florida. Multiple regression analyses indicated that coping self-efficacy was the strongest predictor of general distress and trauma-related distress. Loss of resources and gender were also important predictors of general distress. Path analyses demonstrated that lost resources directly influenced general distress, social support, optimism, and coping self-efficacy. These analyses also indicated that coping self-efficacy perceptions mediated the relationships between loss of resources and trauma-related distress, social support and both trauma and general distress, and optimism and both types of distress. Theoretical implications are discussed.     

The intermodal representation of speech in newborns

It has been proposed that speech is specified by the eye, the ear, and even the skin. Kuhl and Meltzoff (1984) showed that 4-month-olds could lip-read to an extent. Given the age of the infants, it was not clear whether this was a learned skill or a by-product of the primary auditory process. This paper presents evidence that neonate infants (less than 33 h) show virtually identical patterns of intermodal interaction as do 4-month-olds. Since they are neonates, it is unlikely that learning was involved. The results indicate that human speech is specified by both eye and ear at an age when built-in structural sensitivities provide the most plausible explanation.     

Properties of cognitive maps constructed from texts

Subjects in three experiments read texts describing the locations of landmarks in a fictitious town. Later they drew sketch maps and verified sentences describing the relative locations of the landmarks. We predicted that subjects would develop mental models of the town that were organized around important landmarks (“anchors”), as are cognitive maps constructed through real-world navigation. More specifically, we expected that landmarks used in the text as reference points for describing the locations of some other landmarks would emerge as anchors in the subjects’ cognitive maps and would consequently be recalled more accurately. Results showed that subjects represented such reference-point landmarks more accurately than they did the locations of other landmarks. This effect was independent of: (1) the perspective from which the text was written (route or survey); (2) whether or not a map was present at learning; (3) the order of information in the text (linear or anchors-first), and (4) the amount of information available to the subjects while drawing sketch maps (the full text, the landmark names only, or no information).
