The Writing on the (Facebook) Wall: The Use of Social Networking Sites in Hiring Decisions

The popular media has reported an increase in the use of social networking sites (SNSs) such as Facebook by hiring managers and human resource professionals attempting to find more detailed information about job applicants. Within the peer-reviewed literature, cursory empirical evidence exists indicating that others’ judgments of characteristics or attributes of an individual based on information obtained from SNSs may be accurate. Although this predictor method provides a potentially promising source of applicant information on predictor constructs of interest, it is also fraught with potential limitations and legal challenges. The level of publicly available data obtainable by employers is highly unstandardized across applicants, as some applicants will choose not to use SNSs at all while those choosing to use SNSs customize the degree to which information they share is made public to those outside of their network. It is also unclear how decision makers are currently utilizing the available information. Potential discrimination may result through employer’s access to publicly available pictures, videos, biographical information, or other shared information that often allows easy identification of applicant membership to a protected class. For the practice to progress in a positive direction, evidence for the validity and job-relevance of information obtained from SNSs needs to be established. Organizational researchers and practitioners also need to promote awareness and attempt to create safeguards against the potential negative outcomes related to misuse of SNSs by employers.     

Identification of cognitive profiles among women considering BRCA1/2 testing through the utilisation of cluster analytic techniques

Based on the cognitive-social health information processing model, we identified cognitive profiles of women at risk for breast and ovarian cancer. Prior to genetic counselling, participants (N = 171) completed a study questionnaire concerning their cognitive and affective responses to being at genetic risk. Using cluster analysis, four cognitive profiles were generated: (a) high perceived risk/low coping; (b) low value of screening/high expectancy of cancer; (c) moderate perceived risk/moderate efficacy of prevention/low informativeness of test result; and (d) high efficacy of prevention/high coping. The majority of women in Clusters One, Two and Three had no personal history of cancer, whereas Cluster Four consisted almost entirely of women affected with cancer. Women in Cluster One had the highest number of affected relatives and experienced higher levels of distress than women in the other three clusters. These results highlight the need to consider the psychological profile of women undergoing genetic testing when designing counselling interventions and messages.     

Observing response acquisition: preference for unpredictable appetitive rewards obtained under conditions predicted by DMOD

In five E-maze experiments, rats were given a choice between receiving reward and nonreward in a situation where stimuli were correlated with reward outcome (predictable situation) versus one where the stimuli were uncorrelated with reward outcome (unpredictable situation). Preference for the unpredictable situation occurred under the following conditions: (a) small (one 37-mg pellet), immediate rewards; (b) small, delayed (15 s) rewards, if the cues correlated with reward outcome were absent during the delay interval; (c) large (15 pellets), immediate rewards if a difficult discrimination was required; and (d) if the stimulus predicting nonreward was present at the choice point. Preference for the predictable situation was strongest if reinforcement was delayed and large or the stimulus predicting reward was present at the choice point. A weaker preference for the predictable situation occurred if reinforcement was immediate and large and a simple discrimination was required or if reinforcement was large and delayed and the cues that correlated with reward outcome were absent during the delay interval. The results support the predictions of DMOD (Daly modification of the Rescorla-Wagner model), a mathematical model of appetitive learning (Daly & Daly, 1982).     

Is Parent-Offspring Conflict Sex-Linked? Freudian and Darwinian Models

Freud's Oedipal theory sees parent-offspring conflict as a within-gender rivalry, whereas most modern evolutionary models interpret it as a gender-blind disagreement about resource allocation. New analyses of family homicides and a critical review of prior evidence do not support the central Freudian claim of a same-sex contingency in parent-offspring antagonism during the Oedipal phase. Several errors of fact and interpretation in psychoanalytic theorizing about family relations are discussed. We argue that psychoanalysts mistake substantive conflicts between nonrelatives for symbolic manifestations of family conflicts.
