Understanding boundary extension: Normalization and extension errors in picture memory among adults and boys with and without Asperger's syndrome

Boundary extension is the tendency for people to “remember” information that fell outside a picture's boundaries. We used a novel test of boundary extension to provide absolute estimates of the magnitude of extension errors and of the degree to which people are influenced by the way a picture is presented at the time of testing. Participants were shown photographs on a computer and subsequently allowed to adjust their magnification to match the size they remembered. The test produced reliable boundary extension of around 11% in adults and large influences of initial test size. In a second experiment we tested boys diagnosed with Asperger's syndrome and matched controls. Both groups demonstrated boundary extension comparable to that observed in adults but greater effects of initial test size. High performance IQ in Asperger's was linked with high levels of boundary extension, while for the matched control group the opposite pattern was obtained.     

My So-Called Felicity and the City: Coming of Age with and Through Feminist Media Studies

This essay uses autoethnography to investigate the intersection of the dual identities of feminist scholar and media consumer as one mode of investigating television’s role in women’s identity construction. I draw on my experiences with the popular television programs My So-Called Life, Felicity, and Sex and the City as examples of becoming intertwined with the main characters’ relational and purchasing choices on screen. I examine how women of the third wave, raised on television, have come to define our identities by the presence of a man, due in part to the limited, heteronormative media choices available to young women today. The essay closes with a discussion of how the author’s own coming of age as a feminist media scholar parallels the “coming of age” of the discipline of feminist media studies.     

Disentangling the prospective relations between maladaptive cognitions and depressive symptoms

In a four-wave, cohort-longitudinal design with a community sample of 515 children and adolescents (grades 2 through 9), this study examined the longitudinal structure of and prospective interrelations between maladaptive cognitions and depressive symptoms. Multigroup structural equation modeling generated four major findings. First, the longitudinal structures of maladaptive cognitions and depressive symptoms consist of a single time-invariant factor and a series of time-varying factors. Second, evidence supported a model in which depressive symptoms predicted negative cognitions but not the reverse. Third, the time-invariant components of cognition and depression were highly correlated. Fourth, the strength of the depression-to-cognition relation increased with age. Implications regarding the mechanisms underlying clinical interventions with depressed children are discussed.     

Win-shift and win-stay learning in the rainbow lorikeet (Trichoglossus haematodus)

The tendency to win-shift (to better learn to avoid, rather than return to, recently rewarded locations) has been demonstrated in a variety of nectarivorous birds and in honeybees. It is hypothesized to be a cognitive adaptation to the depleting nature of nectar. In the present study we report the first attempt to test for a win-shift bias in a nectarivorous parrot, the rainbow lorikeet (Trichoglossus hematodus). This species differs from others tested for a win-shift bias in that it is a facultative, rather than an obligate, nectarivore. We tested a captive-reared population of the birds on a shift/stay task at long and short retention intervals. The data show no evidence of either a win-shift or a win-stay bias. The birds demonstrated efficient spatial search ability and above chance performance for both shift and stay contingencies at long and short delays. These data suggest that an innate tendency to win-shift may not be present in all avian nectarivores, or that the role experience plays in shaping such behaviors is different for different species.     

Evidence that gendered wording in job advertisements exists and sustains gender inequality

Social dominance theory (Sidanius & Pratto, 1999) contends that institutional-level mechanisms exist that reinforce and perpetuate existing group-based inequalities, but very few such mechanisms have been empirically demonstrated. We propose that gendered wording (i.e., masculine- and feminine-themed words, such as those associated with gender stereotypes) may be a heretofore unacknowledged, institutional-level mechanism of inequality maintenance. Employing both archival and experimental analyses, the present research demonstrates that gendered wording commonly employed in job recruitment materials can maintain gender inequality in traditionally male-dominated occupations. Studies 1 and 2 demonstrated the existence of subtle but systematic wording differences within a randomly sampled set of job advertisements. Results indicated that job advertisements for male-dominated areas employed greater masculine wording (i.e., words associated with male stereotypes, such as leader, competitive, dominant) than advertisements within female-dominated areas. No difference in the presence of feminine wording (i.e., words associated with female stereotypes, such as support, understand, interpersonal) emerged across male- and female-dominated areas. Next, the consequences of highly masculine wording were tested across 3 experimental studies. When job advertisements were constructed to include more masculine than feminine wording, participants perceived more men within these occupations (Study 3), and importantly, women found these jobs less appealing (Studies 4 and 5). Results confirmed that perceptions of belongingness (but not perceived skills) mediated the effect of gendered wording on job appeal (Study 5). The function of gendered wording in maintaining traditional gender divisions, implications for gender parity, and theoretical models of inequality are discussed.     

Suicide, schizophrenia, and schizoid-type psychosis: role of life events and childhood factors

The first objective was to identify the provoking events of suicide in patients with schizophrenia or schizoid-type disorder, and to assess the humiliation component of these events. The second objective was to verify if quality of care during childhood is a vulnerability factor for suicide in patients with schizophrenia or schizoid-type psychosis. Thirty-three cases of suicide with a diagnosis of schizophrenia or schizoid-type psychosis were compared with 34 living patients with a similar diagnosis. The psychological autopsy method was used. The assessments were made with the Structured Clinical Interview for the Diagnostic and Statistical Manual for Axis I mental disorders, the Life Events and Difficulties Schedule, and the Child Experiences and Child Abuse Interview. The suicide group (SG) experienced more often a recent severe event, usually of a humiliation nature, than the control group (CG). It also experienced more severe events associated with aggressive behavior or with psychiatric impairment. Contrary to expectations, the CG had worse scores than the SG for quality of care during childhood. In conclusion, suicide in schizophrenia is related both to environmental stress and to psychiatric impairment.     

The impact of the nature of relationships on perceived burdensomeness and suicide ideation in a community sample of older adults

Older adults die by suicide at very high rates, and previous research indicates that perceived burdensomeness may contribute to deaths by suicide. In this study, the impact of the nature of relationships on perceived burdensomeness and suicide ideation was examined. Results indicated that older adults' perceptions of burden on younger generations were associated with greater overall perceived burdensomeness and suicide ideation when compared to the older adults' own or older generations. Thus, clinicians should examine general perceived burdensomeness as well as the types of relationships the older adult perceives himself or herself to be a burden on.     

Fabrication inflation increases as source monitoring ability decreases

The current research looked at the effects of lying about a false childhood event on the liar's memory for the event. Participants attempted to convince researchers that false events had actually happened to them. In Experiment 1, participants showed a Fabrication Inflation Effect in that they were more likely to increase their beliefs in the lied-about events than control events. Individual differences such as scores on the Dissociative Experience Scale, frequency of lying, and self-reported feelings of discomfort while lying were related to rates of fabrication inflation. In Experiment 2, participants also showed fabrication inflation and were more likely to inflate their likelihood ratings when the lie was created during a separate session from the posttest. Results from both studies support the idea that Source Monitoring failures may cause participants to increase their likelihood ratings of lied-about events. These results suggest that intentional lying may lead some participants to increase their beliefs in their own fabrications. Applications to the legal field are discussed.
