Primed interference: the cognitive and behavioral costs of an incongruity between chronic and primed motivational orientations

Research has shown that temporarily primed motivational orientations have essentially the same effects on how people pursue their goals as their chronic orientations. This article shows that, despite the interchangeability of temporary and chronic motivations, primed motivational orientations that are incongruent with chronic orientations create interference, requiring the deployment of cognitive resources and thus undermining performance on subsequent tasks that rely on these resources. Across 6 studies, we primed motivational orientations that were either congruent or incongruent with participants' chronic orientations and then assessed their performance on subsequent tasks that required cognitive resources. Consistent with the primed interference hypothesis, we found that incongruity between temporary and chronic motivational orientations undermined participants' (a) inhibition of incorrect but highly accessible responses, (b) mental arithmetic, (c) analytical reasoning, and (d) resistance to temptation. These results--which were observed following the activation of motivations for promotion or prevention (Studies 1-2 and 5-6), high or low need for belonging (Study 3), and high or low power orientations (Study 4)--illustrate the broad implications of holding incongruent chronic and primed orientations.     

Shoes as a source of first impressions

Surprisingly minimal appearance cues lead perceivers to accurately judge others’ personality, status, or politics. We investigated people’s precision in judging characteristics of an unknown person, based solely on the shoes he or she wears most often. Participants provided photographs of their shoes, and during a separate session completed self-report measures. Coders rated the shoes on various dimensions, and these ratings were found to correlate with the owners’ personal characteristics. A new group of participants accurately judged the age, gender, income, and attachment anxiety of shoe owners based solely on the pictures. Shoes can indeed be used to evaluate others, at least in some domains.     

The Influence of Families on Early Adolescent School Connectedness: Evidence That This Association Varies with Adolescent Involvement in Peer Drinking Networks

School connectedness is central to the long term well-being of adolescents, and high quality parent–child relationships facilitate school connectedness. This study examined the extent to which family relationship quality is associated with the school connectedness of pre- and early teenagers, and how this association varies with adolescent involvement in peer drinking networks. The sample consisted of 7,372 10–14 year olds recruited from 231 schools in 30 Australian communities. Participants completed the Communities that Care youth survey. A multi-level model of school connectedness was used, with a random term for school-level variation. Key independent variables included family relationship quality, peer drinking networks, and school grade. Control variables included child gender, sensation seeking, depression, child alcohol use, parent education, and language spoken at home. For grade 6 students, the association of family relationship quality and school connectedness was lower when peer drinking networks were present, and this effect was nonsignificant for older (grade 8) students. Post hoc analyses indicated that the effect for family relationship quality on school connectedness was nonsignificant when adolescents in grade 6 reported that the majority of friends consumed alcohol. The results point to the importance of family-school partnerships in early intervention and prevention.     

Neurophysiological preconditions of syntax acquisition

Although the neural network for language processing in the adult brain is well specified, the neural underpinning of language acquisition is still underdetermined. Here, we define the milestones of syntax acquisition and discuss the possible neurophysiological preconditions thereof. Early language learning seems to be based on the bilateral temporal cortices. Subsequent syntax acquisition apparently primarily recruits a neural network involving the left frontal cortex and the temporal cortex connected by a ventrally located fiber system. The late developing ability to comprehend syntactically complex sentences appears to require a neural network that connects Broca’s area to the left posterior temporal cortex via a dorsally located fiber pathway. Thus, acquisition of syntax requires the maturation of fiber bundles connecting the classical language-relevant brain regions.     

How the measurement of memory processes can affect memory performance: the case of remember/know judgments

Relatively little attention has been paid thus far in memory research to the effects of measurement instruments intended to assess memory processes on the constructs being measured. The current article investigates the influence of employing the popular remember/know (R/K) measurement procedure on memory performance itself. This measurement procedure was extensively used in the past to assess the respective contributions of 2 processes to memory judgments, one based on familiarity and the other on recollection. Two experiments using unrelated word pairs showed that the use of an R/K procedure can alter memory performance. Specifically, the R/K procedure improved associative memory among older but not younger adults compared to conditions in which participants were not asked to provide R/K judgments. Such an effect was not observed in item memory performance. Potential mechanisms mediating these differential memory measurement effects are outlined, and the measurement effects' implications for memory and cognitive research are discussed.     

Diurnal patterns of salivary cortisol and DHEA in adolescent anorexia nervosa

Although there is well-documented evidence for hyperactivity of hypothalamic-pituitary-adrenal (HPA) axis function in anorexia nervosa (AN), there has been little research into secretory patterns of salivary cortisol and dehydroepiandrosterone (DHEA) in this condition. The cortisol awakening response (CAR), a prominent and discrete feature of the cortisol cycle, has not been extensively explored in adolescent AN. Saliva samples were collected at awakening, 30?min and 12 h post-awakening on two consecutive weekdays from eight female adolescents with clinically diagnosed AN and 41 healthy control (HC) age-matched females. Adolescent AN patients had greater salivary cortisol and DHEA concentrations than HC girls at all points. Increased hormone secretion was unrelated to body mass index. However, despite hypersecretion of both hormones, the circadian pattern including the CAR paralleled that of the HC group. Findings from this preliminary study confirm dysregulation of HPA axis function in adolescent AN as evidenced by hypersecretion of both cortisol and DHEA, which share the common secretagogue adrenocorticotropic hormone. However, the parallel diurnal profiles for AN and HC participants, including the CAR, may indicate hypersecretion per se rather than differential regulation of the diurnal pattern of these two adrenal steroids in AN.     

Essential Elements of Genetic Cancer Risk Assessment, Counseling, and Testing: Updated Recommendations of the National Society of Genetic Counselors

Updated from their original publication in 2004, these cancer genetic counseling recommendations describe the medical, psychosocial, and ethical ramifications of counseling at-risk individuals through genetic cancer risk assessment with or without genetic testing. They were developed by members of the Practice Issues Subcommittee of the National Society of Genetic Counselors Familial Cancer Risk Counseling Special Interest Group. The information contained in this document is derived from extensive review of the current literature on cancer genetic risk assessment and counseling as well as the personal expertise of genetic counselors specializing in cancer genetics. The recommendations are intended to provide information about the process of genetic counseling and risk assessment for hereditary cancer disorders rather than specific information about individual syndromes. Essential components include the intake, cancer risk assessment, genetic testing for an inherited cancer syndrome, informed consent, disclosure of genetic test results, and psychosocial assessment. These recommendations should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care provider's professional judgment based on the clinical circumstances of a client.
