Ethical issues surrounding human participants research using the Internet

The Internet appears to offer psychologists doing research unrestricted access to infinite amounts and types of data. However, the ethical issues surrounding the use of data and data collection methods are challenging research review boards at many institutions. This article illuminates some of the obstacles facing researchers who wish to take advantage of the Internet's flexibility. The applications of the APA ethical codes for conducting research on human participants on the Internet are reviewed. The principle of beneficence, as well as privacy and confidentiality, informed consent, deception, and avoiding harm are all illustrated through the use of a hypothetical online study.     

Calibrating the sociometer: the relational contingencies of self-esteem

A longitudinal daily diary study examined how chronic perceptions of a partner's regard for oneself might affect the day-to-day relational contingencies of self-esteem. Married partners each completed a diary for 21 days, and completed measures of satisfaction twice over the year. Multilevel analyses revealed that people who chronically felt more positively regarded compensated for one day's acute self-doubts by perceiving greater acceptance and love from their partner on subsequent days. In contrast, people who chronically felt less positively regarded by their partner internalized acute experiences of rejection, feeling worse about themselves on days after they feared their partner's disaffection. Over the year, such self-esteem sensitivity to rejection predicted declines in the partner's satisfaction.     

Intervention for Children Exposed to Interparental Violence (IPV): Assessment of Needs and Research Priorities

In this paper we review the development of interventions for children who have been exposed to interparental violence (IPV), assess current needs in the evaluation of interventions, and provide suggestions for research priorities in this area. Interventions for negative outcomes associated with exposure to IPV only recently have been carefully designed and evaluated, thus knowledge regarding program effectiveness is minimal. Three of the most comprehensive interventions that have been evaluated are presented. Each has demonstrated effectiveness, and focuses on children with different levels of symptoms and distress. However, many questions remain regarding which interventions are beneficial for diverse children with different kinds and intensities of problems. A number of research priorities and suggestions for further improvements in the evaluation of effectiveness of interventions are identified.     

Good pitch memory is widespread

Abstract - Here we show that good pitch memory is widespread among adults with no musical training. We tested unselected college students on their memory for the pitch level of instrumental soundtracks from familiar television programs. Participants heard 5-s excerpts either at the original pitch level or shifted upward or downward by 1 or 2 semitones. They successfully identified the original pitch levels. Other participants who heard comparable excerpts from unfamiliar recordings could not do so. These findings reveal that ordinary listeners retain fine-grained information about pitch level over extended periods. Adults' reportedly poor memory for pitch is likely to be a by-product of their inability to name isolated pitches.     

Chunking versus foraging search patterns by rats in the hierarchically baited radial maze

Rats were exposed to a radial maze containing six black smooth arms and six wire-grid-covered arms and a striped 'exit arm' in experiment 1. The probability of a black or grid arm being baited (5/6 vs 1/6) with sunflower seeds was associated with its proximal cue for some rats (the Relevant Arm Cue group) but not for others (the Irrelevant Arm Cue group). All rats could terminate a trial and receive a highly preferred morsel of apple by entering the exit arm only after having sampled all six seed-baited arms. Relevant Arm Cue rats usually chose some arms from the more densely baited set before choosing an arm from the less densely baited set and made fewer reentries than Irrelevant Arm Cue rats. Although such clustered, higher choice accuracy in the Relevant Arm Cue group corresponds to human clustered, better recall of verbal items from lists hierarchically organized by categories, these rats did not similarly exhaustively retrieve items (arm locations). That is, when required to terminate a trial by entering the 'exit' arm for an apple morsel after having sampled all seed-baited arms, both groups were equally unable to withhold making nonrewarded premature exits. This nonexhaustive foraging search pattern was maintained in the next two experiments in which the radial maze was reduced to three black and three grid arms along with the striped 'exit' arm and in which black and grid arm cues were paired with number of seeds (eight or one) in an arm for Relevant Arm Cue rats. Although Relevant Arm Cue rats displayed perfect clustering by entering all eight-seeded arms before a one-seeded arm, they made more premature exits and reentries into eight-seeded arms in experiment 2 or when forced to enter all eight-seeded arms in experiment 3 than did Irrelevant Arm Cue rats. These foraging tendencies prevent accurate estimations of the amount of information (i.e., arm locations) rats can 'chunk'. Electronic Publication     

Why simple verb forms can be so difficult to spell: the influence of homophone frequency and distance in Dutch.

Two experiments are reported in which the determinants of spelling errors on homophonous verb forms in Dutch were studied. Both experiments indicated that errors were determined by the frequency relationship between the two homophonous forms and the distance between the verb and the word determining its spelling. We propose an interference model for spelling in which a phonologically driven retrieval process is the locus of the frequency effect and a morphosyntactically driven computational component can account for the distance effect. Alternative explanations are also explored.     

Specifying the scope of 13-month-olds'' expectations for novel words

Recent research has documented that for infants as young as 12–13 months of age, novel words (both count nouns and adjectives) highlight commonalities among objects and, in this way, foster the formation of object categories. The current experiment was designed to capture more precisely the scope of this phenomenon. We asked whether novel words (count nouns; adjectives) are linked specifically to category-based commonalities from the start, or whether they also direct infants' attention to a wider range of commonalities, including property-based commonalities among objects (e.g. color, texture). The results indicate that by 12–13 months, (1) infants have begun to distinguish between novel words presented as count nouns versus. adjectives in fluent, infant-directed speech, and (2) infants expectations for novel words accord with this emerging sensitivity.     

Development of the Critical Elements of Genetic Evaluation and Genetic Counseling for Genetic Professionals and Perinatologists in Washington State

We present a method for the development of consensus documents describing the components of genetic evaluation and genetic counseling for various diagnoses. These documents were developed to encourage consistency among genetic professionals in Washington State. Other possible uses of these documents are to provide information regarding genetic evaluations for health care practitioners and payers, and to assist in quality assurance and genetic training programs. A working group of six genetic professionals developed two templates for the critical elements of genetic evaluation and genetic counseling, for clinical (nonprenatal) and prenatal patients. The working group then completed prototype templates for several specific genetic disorders. The templates and prototypes were sent to interested genetic professionals and perinatologists who submitted a total of 76 draft critical elements (CE's) to the working group. At two statewide meetings, participating practitioners modified and unanimously approved the CE templates, then unanimously approved the 21 draft CEs that had been finalized in small group discussions. Approved CE's were distributed to genetic professionals and perinatologists within the state.     

Subjectivity and Class Consciousness: The Development of Class Identity

In this paper, the author explores issues of self and identity, in particular the development of consciousness of social class and the negotiation of conflicting class identities. Literature on working-class students and academics from the working class indicates that upward mobility from working class to professional class can be disorienting due to class-related sociocultural differences and the internalization of class conflicts. By drawing upon one case from an ethnographic study with ten female professors from the working class, the author explores the development of one woman's working-class consciousness and the ways in which it influenced her teaching. Detailed analyses of three narratives from one interview are presented that highlight particular contexts and events in a process of class identity development.
