Sensitivity to status-based rejection: implications for African American students' college experience

The authors proposed a process model whereby experiences of rejection based on membership in a devalued group can lead people to anxiously expect, readily perceive, and intensely react to status-based rejection. To test the model, the authors focused on race-based rejection sensitivity (RS-race) among African Americans. Following the development and validation of the RS-Race Questionnaire (Studies 1 and 2), the authors tested the utility of the model for understanding African American students' experiences at a predominantly White university (Study 3). Students high in RS-race experienced greater discomfort during the college transition, less trust in the university, and relative declines in grades over a 2- to 3-year period. Positive race-related experiences, however, increased feelings of belonging at the institution among students high in RS-race.     

Stress and reproduction: central mechanisms and sex differences in non-rodent species

Despite extensive research, the mechanisms by which stress affects reproduction are unknown. Activation of stress systems could potentially influence reproduction at any level of the hypothalamo-pituitary gonadal axis. Nonetheless, the predominant impact is on the secretion of gonadotrophin releasing hormone (GnRH) from the brain and the secretion of the gonadotrophins, luteinizing hormone (LH) and follicle stimulating hormone (FSH), from the gonadotrophs of the anterior pituitary gland. When stress is prolonged, it is likely that secretion of the gonadotrophins will be suppressed but the effects of acute stress or repeated acute stress are not clear. Different stressors activate different pathways for varying durations, and the actions of stress vary with sex and are influenced by the predominance of particular sex steroids in the circulation. The mechanisms by which stress influences reproduction are likely to involve complex interactions between a number of central and peripheral pathways and may be different in males and females. To understand these mechanisms, it is important to determine the stress pathways that are activated by particular stressors and to establish how these pathways affect the secretion and actions of GnRH. Furthermore, there is a need to know how stress influences the feedback actions of gonadal steroids and inhibin.     

Links between social and linguistic processing of speech in preschool children with autism: behavioral and electrophysiological measures

Data on typically developing children suggest a link between social interaction and language learning, a finding of interest both to theories of language and theories of autism. In this study, we examined social and linguistic processing of speech in preschool children with autism spectrum disorder (ASD) and typically developing chronologically matched (TDCA) and mental age matched (TDMA) children. The social measure was an auditory preference test that pitted 'motherese' speech samples against non-speech analogs of the same signals. The linguistic measure was phonetic discrimination assessed with mismatch negativity (MMN), an event-related potential (ERP). As a group, children with ASD differed from controls by: (a) demonstrating a preference for the non-speech analog signals, and (b) failing to show a significant MMN in response to a syllable change. When ASD children were divided into subgroups based on auditory preference, and the ERP data reanalyzed, ASD children who preferred non-speech still failed to show an MMN, whereas ASD children who preferred motherese did not differ from the controls. The data support the hypothesis of an association between social and linguistic processing in children with ASD.

Confirming satisfaction as an attitude within the service‐buying process

This paper presents research that uses cognitive and affective semantic differential scales to construct an attitude measuring instrument to be used in the services domain in the context of long applications to buy a service. The scales measure ‘Attitude to the Application Process’ (AAP) which represents satisfaction, as an internal ‘buying process’ attitude, which moderates the buying intention. Data collected over a three‐year period between 1996‐9, was analysed using exploratory and confirmatory factor analyses. The results provide evidence of a robust and useful cognitive scale. Although there were anomalies in the exploratory and confirmatory analysis of the affective scale, a robust scale is presented which represents either one or two factors. The whole measuring instrument of 14 items was developed as a means to access applicant attitudes during the application process to university — an extended and extreme application situation for first‐time consumers. The results identify that the instrument is sound and can be used in its original or modified form, depending on the context of the service‐process monitoring situation. The scales represent aspects of attitude not dealt with extensively in the literature and measure the perception of the application process as simple, open, friendly and helpful. These aspects of satisfaction mirror three attributes of service quality: assurance, responsiveness and empathy identified in previous research. Copyright © 2001 Henry Stewart Publications.
