Accuracy and Bias in Perceptions of Spouses' Life‐Sustaining Medical Treatment Preferences1

This research investigated accuracy, projection bias, and base‐rate utilization in spouses' perceptions of end‐stage renal disease patients' preferences for life‐sustaining medical treatment in hypothetical conditions of declining health. Multilevel models revealed that spouses' perceptions were largely biased, determined by their own preferences for the patients' treatment (projection bias) and by typical treatment preferences (base‐rate utilization). Both biases, however, served as indirect routes to a modest degree of accuracy. Moreover, spouses who overestimated patients' preferences for life‐sustaining treatment and who perceived patients' preferences as consistent with their own reported higher levels of marital adjustment than did those who were less biased. Results suggest that spouses' biases in judgments of patients' treatment preferences may promote accuracy and marital adjustment functionally.     

Musical preference, deviance, and attitudes towards music celebrities

Two studies investigated the relationship among British students between liking for ‘problem’ music, indices of deviance, and scores on a slightly modified version of the Celebrity Attitude Scale (CAS). Study 1 indicated a positive relationship between liking for ‘problem’ music styles and psychoticism scores. Study 2 indicated that fans of ‘problem’ music scored higher than non-fans on measures of psychoticism, reactive rebelliousness, and two specific problem behaviours; that liking for ‘problem’ music was related only to psychoticism when all the indices of deviance were considered together in a multiple regression; and that fans of ‘problem’ music did not score higher on CAS measures of identification with the participants’ favourite musicians. The present data indicate a relationship outside North America between ‘problem’ music and deviance, that this might be attributable primarily to elevated psychoticism scores among listeners to this music, but that liking for ‘problem’ music was not associated with a greater tendency for participants to identify closely with licentious behaviours carried out by pop musicians.     

The More You See It, the More You Know It: Memory Accessibility and Sexual Harassment Judgments

The influence of the availability of personally known and media known sexual harassment victims and harassers on perceptions of social sexual workplace conduct was examined. Male and female full-time workers evaluated two videotapes that depict sexual harassment in the workplace. Results indicated that perceived likelihood of harassment and discrimination increased as participants recalled more examples of harassment victims whom they personally knew. In some instances, recall of victims in the media had a similar influence. As predicted, the influence of availability was stronger for men than for women. Similar findings resulted from the analyses of the unwelcomeness, severity, and pervasiveness of the conduct; however, legal standard, gender, or case often moderated this relationship. The implications of these findings are discussed.     

The efficiency of feature-based subitization and counting

The enumeration of small numbers of objects (approximately 4) proceeds rapidly, accurately, and with little effort via a process termed subitization. Four experiments examined whether it was possible to subitize the number of features rather than objects present in a display. Overall, the findings showed that when features are presented randomly and are uncorrelated with object numerosity, efficient enumeration is not possible. This suggests that the visual system does not have parallel access to multiple feature maps and that subitization processes operate exclusively on representations coding the locations of objects. The data are discussed with respect to theories of visual enumeration and search.     

Search, enumeration, and aging: eye movement requirements cause age-equivalent performance in enumeration but not in search tasks

Response time (RT) and fixation frequency were measured for young and older adults in search and enumeration tasks under high- and low-attentional competition conditions. There was an age-related decrement in search rates for single targets both for RT and fixation frequency, but there was no deficit in enumeration rates either with or without distractors even though serial enumeration rates were much slower than single target search rates. Fixation frequency per item in serial enumeration was much greater than in serial visual search for a single target. Enumerating targets with distractors produced an overall increase in RT and fixation frequency that was greater for older adults. The data are contrary to a generalized slowing account, and an alternative is proposed on the basis of the need to make eye movements in enumeration but not in search tasks.     

Identifying vulnerability markers in prodromal patients: a step in the right direction for schizophrenia prevention

Research has shown that many of the long-term deficits that are observable in schizophrenia populations are present prior to the emergence of psychotic symptoms. Recent research suggests schizophrenia has a "prodromal" period, whereby significant changes from premorbid functioning can be observed. Accurate classification of this period could have far-reaching implications for schizophrenia prevention. This article aims to provide an indepth evaluation of the perceived benefits of vulnerability marker research in this unique phase. It is hoped that identification of such markers may improve the predictive potency of prodromal criteria, and perhaps pave the way for future screening and primary prevention strategies.     

Maternal expressed emotion predicts children's antisocial behavior problems: using monozygotic-twin differences to identify environmental effects on behavioral development

If maternal expressed emotion is an environmental risk factor for children's antisocial behavior problems, it should account for behavioral differences between siblings growing up in the same family even after genetic influences on children's behavior problems are taken into account. This hypothesis was tested in the Environmental Risk Longitudinal Twin Study with a nationally representative 1994-1995 birth cohort of twins. The authors interviewed the mothers of 565 five-year-old monozygotic (MZ) twin pairs and established which twin in each family received more negative emotional expression and which twin received more warmth. Within MZ pairs, the twin receiving more maternal negativity and less warmth had more antisocial behavior problems. Qualitative interviews were used to generate hypotheses about why mothers treat their children differently. The results suggest that maternal emotional attitudes toward children may play a causal role in the development of antisocial behavior and illustrate how genetically informative research can inform tests of socialization hypotheses.     

The effects of memory trace strength on eyewitness recall in children with and without intellectual disabilities

Children with mild moderate intellectual disabilities (ID) were compared with typically developing peers of the same chronological age (CA) on an eyewitness memory task in which memory trace strength was manipulated to examine whether increased memory trace strength would benefit those with ID more than those without ID. No evidence was found for this claim or for the notion that different mechanisms are implicated in memory processes for children with ID versus CA controls. Fuzzy-trace theory was also used to contrast question types that probed verbatim memory versus gist memory. Manipulations of trace strength, when used with immediate recall (to reduce the impact of decay), were predicted to improve verbatim memory more than gist memory. The results broadly supported the predictions. Performance was not improved in the stronger trace strength condition on measures of recall that tapped gist memory (e.g., open-ended recall), whereas performance was significantly better in the stronger trace strength condition on two of the three measures of recall that tapped verbatim memory (i.e., closed misleading questions, open-ended specific questions). Differences in performance between the groups were quite marked on several question types, supporting previous findings that those with ID have certain vulnerabilities as potential witnesses compared with peers of the same CA.     

The wish for revenge

The wish for revenge is a ubiquitous response to narcissistic injury, and particularly to the narcissistic injury that accompanies oedipal defeat. Vengeful fantasy serves to represent and manage rage and to restore the disrupted sense of self and internalized imagining audience that have resulted from injury. Clinical and literary examples demonstrate the split within the representation of the self and the imagining other that underlies the wish for revenge, and the way that this split operates differently in the psychic economy of the transiently and the chronically vengeful.
