Prototypicality in sentence production

Three cued-recall experiments examined the effect of category typicality on the ordering of words in sentence production. Past research has found that typical items tend to be mentioned before atypical items in a phrase—a pattern usually associated with lexical variables (like word frequency), and yet typicality is a conceptual variable. Experiment 1 revealed that an appropriate conceptual framework was necessary to yield the typicality effect. Experiment 2 tested ad hoc categories that do not have prior representations in long-term memory and yielded no typicality effect. Experiment 3 used carefully matched sentences in which two category members appeared in the same or in different phrases. Typicality affected word order only when the two words appeared in the same phrase. These results are consistent with an account in which typicality has its origin in conceptual structure, which leads to differences in lexical accessibility in appropriate contexts.     

Are memories for sexually traumatic events "special"? A within-subjects investigation of trauma and memory in a clinical sample

According to a long-standing clinical tradition, sexually traumatic experiences are processed and recalled differently from other experiences, often leading to memory impairment. In this study, we compared the characteristics of traumatic memories for sexual violence and two other types of emotional experiences. N=44 women recruited from a local sexual trauma agency were asked to recall and describe three autobiographical events: sexual abuse/assault, a non-sexual trauma, and a positive emotional event. The characteristics of the three memory types were compared on both subjective and objective measures. Further, the potential influences of level of traumatic impact and dissociation were assessed. Results indicated that memories for sexual trauma were not impaired or fragmented relative to other memories. Instead, memories for sexual trauma were associated with a remarkably high level of vividness, detail, and sensory components. Further, high levels of traumatic impact were not associated with memory impairment. Implications for the ongoing traumatic memory debate are discussed.     

Comparing online and lab methods in a problem-solving experiment

Online experiments have recently become very popular, and--in comparison with traditional lab experiments--they may have several advantages, such as reduced demand characteristics, automation, and generalizability of results to wider populations (Birnbaum, 2004; Reips, 2000, 2002a, 2002b). We replicated Dandurand, Bowen, and Shultz's (2004) lab-based problem-solving experiment as an Internet experiment. Consistent with previous results, we found that participants who watched demonstrations of successful problem-solving sessions or who read instructions outperformed those who were told only that they solved problems correctly or not. Online participants were less accurate than lab participants, but there was no interaction with learning condition. Thus, we conclude that online and Internet results are consistent. Disadvantages included high dropout rate for online participants; however, combining the online experiment with the department subject pool worked well.     

The Effect of Secrecy and Social Support on Behavioral Problems in Children of Incarcerated Women

We investigated the effects of secrecy regarding their mothers' incarceration and social support on behavioral problems in a group of 116 children (aged 6–13 years, M = 9.00). Children with low levels of social support had more externalizing and internalizing problems, and children who had experienced more life stressors reported more internalizing problems. Significant interactions indicated that both externalizing and internalizing problem scores were higher for children whose social support was poor and secrecy scores were low. Our findings suggest that for children already suffering from little or no support from key people, having little or no constraints regarding talking about mothers' incarceration places children at risk for developing behavioral problems. We discuss explanations for the findings and implications for caregivers.     

Computer- and internet-based psychotherapy interventions

Computers and Internet-based programs have great potential to make psychological assessment and treatment more cost-effective. Computer-assisted therapy appears to be as effective as face-to-face treatment for treating anxiety disorders and depression. Internet support groups also may be effective and have advantages over face-to-face therapy. However, research on this approach remains meager.     

Extracting the Variance Inflation Factor and Other Multicollinearity Diagnostics from Typical Regression Results

Multicollinearity is a potential problem in all regression analyses. However, the examination of multicollinearity is rarely reported in primary studies. In this article we discuss and show several post hoc methods for assessing multicollinearity. One such multicollinearity diagnostic is the variance inflation factor. We outline the post hoc variance inflation factor method, which computes the variance inflation factor from the standardized regression coefficient and semi-partial correlation, both of which can be calculated from commonly reported regression results. Three examples of computing multicollinearity diagnostics using data from published studies are shown. We conclude with a discussion and practical implications.     

Ethical Challenges for Military Psychologists: When Worlds Collide

Despite the mental health needs in the military and improved access to military psychologists, many in need do not seek psychological services. The military policies, culture, and environment pose considerable barriers to help seeking. In turn, military practices often conflict with the psychologist’s professional ethics, leading to a range of ethical dilemmas including multiple relationships, multiple agencies, and limited confidentiality. To address ethical concerns and encourage service members to seek mental health services, this article proposes maintaining an understanding of military rules, law, and professional ethics; identifying multiple relationships and establishing boundaries up front; and collaborating with the patient in disclosures of information.     

I Can't Wait to Get Married: Gender Differences in Drive to Marry

In this study we examined a new construct—the Drive to Marry (DTM). Young single men and women (149 men and 246 women) rated their desire to get married and completed measures of their valuing of marital, parental, and occupational roles; concern about others' views of them; and feminist attitudes. We found that women had a higher DTM than did men. In both genders, DTM was predicted by the value of parental role and by concern about others' views of them. In women, DTM was also predicted by traditional attitudes toward gender roles, and there was a trend for women who valued the occupational role to have a lower DTM. Conservative women, women who valued the parental role, and women with a higher DTM were also more likely to want to use the title “Mrs.” and to adopt their husband's surname. An earlier version of this paper was presented at the annual meeting of the Midwestern Psychological Association in May 2004.
