The influence of Sociocultural Paradigms

This research examined the influence of sociocultural paradigms of menopause on attitudes toward menopause. Five hundred eighty-one women and men, between the ages of 18 and 85, were assigned to one of three groups distinguished by the context within which they expressed their attitudes toward menopause. The contexts were designed to reflect particular paradigms: one group described their attitudes toward three medical problems, including menopause; a second group described their attitudes toward three life transitions, including menopause; and a third group described their attitudes toward three symbols of aging, including menopause. Positive and negative subscales of the attitude questionnaires for menopause were analyzed for context and age/experience. Results indicated that the medical context elicited significantly more negative and fewer positive attitudes than did the other two contexts, particularly among older participants. In general, women's attitudes were more positive than were men's, and attitudes became increasingly positive with age and/or experience. The discussion includes the potential role of attitudes as mediating the impact of sociocultural paradigms on experience and behavior.     

Answer comparison in automated question answering

In the context of Question Answering (QA) on free text, we assess the value of answer comparison and information fusion in handling multiple answers. We report improvements in answer re-ranking using fusion on a set of location questions and show the advantages of considering candidates as allies rather than competitors. We conclude with some observations about answer modeling and evaluation methodology, arising from a more recent experiment with a larger set of questions and a greater diversity of question types and candidates.     

The Role of Parenting in Relational Aggression and Prosocial Behavior among Emerging Adults

This study investigated the role of remembered parenting styles and parental psychological control in the prediction of relational aggression and prosocial behavior in a college student sample (N = 323). Participants’ retrospective ratings of how they were parented were related to relational aggression and prosocial behavior; however, somewhat different relationships emerged for African American and White participants. Permissive parenting, authoritative parenting, and parental psychological control predicted relational aggression. Participant race and all 3 parenting styles (authoritarian, authoritative, and permissive) predicted prosocial behavior. Participant race moderated the relationship between psychological control and prosocial behavior. Specifically, parental psychological control was inversely related to prosocial behavior for African American, but not White, participants.     

Social networking site use: Linked to adolescents' social self‐concept,self‐esteem,and depressed mood

Adolescents spend a substantial amount of time using social networking sites (SNSs); however, little is known regarding whether such use is associated with indicators of adjustment. The present study employed a multidimensional measure of SNS use to investigate the link between Australian adolescent SNS use and indicators of adjustment. Youth (N = 1,819, 55% female) from 34 diverse high schools across Western Australia were surveyed. The results showed that frequency of SNS use was linked to higher social self‐concept while investment in SNSs was associated with lower self‐esteem and higher depressed mood. Furthermore, having an SNS was linked to more negative indicators for female adolescents compared with male adolescents, although the link between frequency of use and investment in SNSs to indicators of adjustment was not moderated by gender. The present study highlights the complexity of the relationship between adolescent SNS use and indicators of adjustment, and offers insight into the diverse types of adolescent use of SNSs.     

Knowledge about the probability of change affects change detection performance

The visual system continually selects some information for processing while bypassing the processing of other information, and as a consequence, participants often fail to notice large changes to visual stimuli. In the present studies, the authors investigated whether knowledge about the probability of particular changes occurring over time increased the likelihood that changes that were likely to occur in the real world (probable changes) would be detected. The results of two experiments showed that participants were more likely to detect probable changes. This occurred whether or not they were processing the scene in a meaningful manner or actively searching the scene for changes. Furthermore, participants were unable to accurately predict change detection performance for probable and improbable changes.     

Avoidance learning facilitates temporal processing in the primary auditory cortex

The primary auditory cortex is now known to be involved in learning and memory, as well as auditory perception. For example, spectral tuning often shifts toward or to the frequency of the conditioned stimulus during associative learning. As previous research has focused on tonal frequency, less is known about how learning might alter temporal parameters of response in the auditory cortex. This study addressed the effects of learning on the fidelity of temporal processing. Adult male rats were trained to avoid shock that was signaled by an 8.0 kHz tone. A novel control group received non-contingent tone and shock with shock probability decreasing over days to match the reduced number of shocks received by the avoidance group as they mastered the task. An untrained (nai ve) group served as a baseline. Following training, neuronal responses to white noise and a broad spectrum of tones were determined across the primary auditory cortex in a terminal experiment with subjects under general anesthesia. Avoidance conditioning significantly improved the precision of spike-timing: the coefficient of variation of 1st spike latency was significantly reduced in avoidance animals compared to controls and nai ves, both for tones and for noise. Additionally, avoidance learning was accompanied by a reduction of the latency of peak response, by 2.0-2.5 ms relative to nai ves and approximately 1.0 ms relative to controls. The shock-matched controls also exhibited significantly shorter peak latency of response than nai ves, demonstrating the importance of this non-avoidance control. Plasticity of temporal processing showed no evidence of frequency specificity and developed independently of the non-temporal parameters magnitude of response, frequency tuning and neural threshold, none of which were facilitated. The facilitation of temporal processing suggests that avoidance learning may increase synaptic strength either within the auditory cortex, in the subcortical auditory system, or both.     

Children's Narratives Following Traumatic Brain Injury: Linguistic Structure, Cohesion, and Thematic Recall

Narrative discourse and intellectual functioning were examined 3 years following traumatic brain injury (TBI) in children 1 to 8 years of age at the time of injury. The language-impaired TBI group (n= 9) had language deficits during the subacute stage of recovery; their performance was contrasted with that of a TBI comparison group equated on neurologic and demographic variables that did not show subacute language impairment (n= 8) and a sibling comparison group (n= 9). The language-impaired TBI group had lower Verbal and Full-Scale IQ scores and produced fewer words and utterances than the sibling group on a story retelling task; their stories were characterized by fewer complete referential and lexical ties and more referential errors, indicating difficulty conjoining meaning across sentences. The language-impaired TBI group recalled approximately one-third of the propositions needed to maintain the story theme and made more errors sequencing the propositions than either the TBI or the sibling comparison groups. Group differences were not obtained on the Performance IQ scores or on measures of rate or fluency of speech production, mazes, use of conjunctives, or naming errors. The discourse deficiencies of children with TBI and acute language impairment were most pronounced at the level of cognitive organization of the text reflecting text macrostructure and were least apparent at the level of lexical and sentential organization reflecting text microstructure. Results are discussed in terms of the vulnerability of developing language abilities to disruption by brain injury.
