Detecting silent pauses in speech: a new tool for measuring on-line lexical and semantic processing

In this study, we introduce pause detection (PD) as a new tool for studying the on-line integration of lexical and semantic information during speech comprehension. When listeners were asked to detect 200-ms pauses inserted into the last words of spoken sentences, their detection latencies were influenced by the lexical-semantic information provided by the sentences. Listeners took longer to detect a pause when it was inserted within a word that had multiple potential endings, rather than a unique ending, in the context of the sentence. An event-related potential (ERP) variant of the PD procedure revealed brain correlates of pauses as early as 101 to 125 ms following pause onset and patterns of lexical-semantic integration that mirrored those obtained with PD within 160 ms of pause onset. Thus, both the behavioral and the electrophysiological responses to pauses suggest that lexical and semantic processes are highly interactive and that their integration occurs rapidly during speech comprehension.     

The Genetic Counseling Workplace—An Australasian Perspective. A National Study of Workplace Issues for Genetic Counselors and Associate Genetic Counselors

Genetic counseling in Australasia (Australia and New Zealand) has been recognized as a profession since the 1980s and has steadily expanded over the past 20 years. The demography of major cities with metropolitan sprawl and sparsely populated rural areas has led to the establishment of 3 types of genetics units: main units in cities, metropolitan outreach, and rural outreach units. A questionnaire was developed to obtain information about the needs, resources, and day-to-day operation of the genetic counselors. The questionnaire addressed the areas of resource availability, professional development, responsibility of genetic counselors in the clinical setting, and their involvement in promotion of the service and public education. Differences observed between the 3 settings in all of these areas included large clinical loads for metropolitan outreach counselors, varying responsibilities in the clinical setting, and a lack of support and resources for rural outreach counselors. Australasian Genetic counselors were found to have a significant interest in developing mechanisms for supervision and were keenly interested in maintaining credentials and professional role development. The results of this study allows genetic counselors themselves to have a better understanding of the roles of their colleagues in the different units; they can also be used by service providers in establishing and supporting genetic counselors, and identifying inequalities and deficiencies in the different practice areas.     

What Do We Know About Neuropsychological Aspects Of Schizophrenia?

Application of a neuropsychological perspective to the study of schizophrenia has established a number of important facts about this disorder. Some of the key findings from the existing literature are that, while neurocognitive impairment is present in most, if not all, persons with schizophrenia, there is both substantial interpatient heterogeneity and remarkable within-patient stability of cognitive function over the long-term course of the illness. Such findings have contributed to the firm establishment of neurobiologic models of schizophrenia, and thereby help to reduce the social stigma that was sometimes associated with purely psychogenic models popular during parts of the 20th century. Neuropsychological studies in recent decades have established the primacy of cognitive functions over psychopathologic symptoms as determinants of functional capacity and independence in everyday functioning. Although the cognitive benefits of both conventional and even second generation antipsychotic medications appear marginal at best, recognition of the primacy of cognitive deficits as determinants of functional disability in schizophrenia has catalyzed recent efforts to develop targeted treatments for the cognitive deficits of this disorder. Despite these accomplishments, however, some issues remain to be resolved. Efforts to firmly establish the specific neurocognitive/neuropathologic systems responsible for schizophrenia remain elusive, as do efforts to definitively demonstrate the specific cognitive deficits underlying specific forms of functional impairment. Further progress may be fostered by recent initiatives to integrate neuropsychological studies with experimental neuroscience, perhaps leading to measures of deficits in cognitive processes more clearly associated with specific, identifiable brain systems.

Emotional and cognitive health correlates of leisure activities in older Latino and Caucasian women

This study examined differences in the frequency of leisure activity participation and relationships to depressive symptom burden and cognition in Latino and Caucasian women. Cross-sectional data were obtained from a demographically matched subsample of Latino and Caucasian (n?=?113 each) postmenopausal women (age ≥60 years), interviewed in 2004-2006 for a multiethnic cohort study of successful aging in San Diego County. Frequencies of engagement in 16 leisure activities and associations between objective cognitive performance and depressive symptom burden by ethnicity were identified using bivariate and linear regression, adjusted for physical functioning and demographic covariates. Compared to Caucasian women, Latinas were significantly more likely to be caregivers and used computers less often. Engaging in organized social activity was associated with fewer depressive symptoms in both groups. Listening to the radio was positively correlated with lower depressive symptom burden for Latinas and better cognitive functioning in Caucasians. Cognitive functioning was better in Latinas who read and did puzzles. Housework was negatively associated with Latinas' emotional health and Caucasians' cognitive functioning. Latino and Caucasian women participate in different patterns of leisure activities. Additionally, ethnicity significantly affects the relationship between leisure activities and both emotional and cognitive health.     

The malleable bicultural consumer: effects of cultural contexts on aesthetic judgments

• Grounded in the cognitive framework of processing fluency, this study proposes further support for the experiential perspective in aesthetics by positing that aesthetic response to the same object may be malleable, depending on how the symbolic properties of the object interact with different cultural contexts which either facilitate or debilitate the processing experience of the perceiver. The study employed an Internet experiment to test the hypotheses among 105 female Hispanic college‐aged students enrolled at a large midwestern university. The findings revealed that symbolic attributes of products interact with cultural contexts to affect aesthetic judgments of (Hispanic) consumers. Aesthetic judgments were more positive when evaluating culturally symbolic product attributes after exposure to congruent contextual cues that facilitate fluent processing. The study furnishes support for the impact of environment/context on consumer behavior and aesthetic judgment, thus establishing further support for the cognitive framework of conceptual fluency in explaining aesthetic response. The study also contributes to recent literature on “frame‐switching” among bicultural consumers by suggesting that these consumers navigate between competing cultural frames in response to visual primes, with resultant shifts in aesthetic judgments. Important marketing insights emerge from these findings.

Video‐based Testing: A high‐fidelity job simulation that demonstrates reliability,validity, and utility

A conceptual rationale is presented for the use of a high‐fidelity simulation: a video‐based test (VBT), in which applicants view job‐related scenarios, respond orally, and are later scored on five dimensions by trained raters. Using applicant data, we empirically investigate the criterion‐related validity, reliability, and utility of the VBT. Overall, we found that the VBT predicted performance in training and on the job. In addition, different raters strongly agreed with one another on each applicant's scores. Despite somewhat higher development costs, the VBT demonstrated high utility. We suggest that organizations consider the use of VBTs as a selection instrument for jobs that require the use of applied social and interpersonal skills.     

Cognitive,affective and conative responses to visual simulation: the effects of rotation in online product presentation

• Rotation, one type of visual simulation used to create three‐dimensional (3‐D) experiences, and currently being used for product presentation on some e‐tail websites, may create consumer responses. Therefore, the purpose of this study is to examine the effects of rotation in product presentation on the cognitive, affective, and conative responses of consumers. This study employed a single‐factor between‐subjects design: product presentation (rotating vs. non‐rotating). Causal model analysis showed the influence of rotation in product presentation on perceived information quantity, mood, attitude, and purchase intention. Theoretical and managerial implications, as well as future research directions, are discussed.
