Seeing reversals in ambiguous images: to know or not to know?

The present study is an attempt to replicate the 1992 findings of Rock and Mitchener that knowing about the ambiguity in ambiguous images is necessary for seeing reversals. In contrast to Rock and Mitchener's study, the present study used a between-subjects design, in which 190 participants were randomly assigned to either an uninformed or an informed condition, and saw 12 images, 6 ambiguous and 6 unambiguous. The findings show that participants in the informed condition were significantly more likely to see reversals in the ambiguous images than were those in the uninformed condition. In contrast to Rock and Mitchener's findings, knowledge of ambiguity did not ensure that all informed participants saw all six reversals; there were spontaneous reversals in the uninformed condition for most of the images. These findings are discussed in terms of suggesting that seeing a reversal in an ambiguous image is a complex process that requires consideration of the interplay of visual perception and higher order cognition.

Examining the role of trauma, personality, and meaning in young prolonged grievers.

PURPOSE: Younger spouses or partners have been understudied in the prolonged grief literature. The purpose of this study was to determine rates of prolonged grief in young spouses or partners and the associations between prolonged grief and personality styles (specifically, narcissistic, histrionic, and obsessive), trauma history, and the perceived meaning of the loss in the young conjugally bereaved. PARTICIPANTS AND METHOD: Participants between 20 and 50 years old who lost a spouse/partner to cancer 6 months-3 years prior to the study completed the following measures during one time point (via phone or in person interviews): Prolonged Grief-13, traumatic life events questionnaire, Millon clinical multiaxial inventory-III, and grief meaning reconstruction inventory. RESULTS: Fifty-six spouses and partners (51.8% women) completed the interviews (mean age: 44.54 ± 4.20 years). The participants (49.1%) reported elevated rates of prolonged grief and 12.3% of the participants were diagnosed with prolonged grief with the recently published diagnostic algorithm. Bivariate analyses demonstrated an association between prolonged grief and negative meaning of the loss (r = 0.73; p < 0.01) and the frequency of the traumatic events (r = 0.23; p < 0.05). Multivariate analyses revealed that negative meaning of the loss was the only significant predictor of prolonged grief (Beta = 0.71; p = 0.0001). CONCLUSION: Elevated levels of prolonged grief were found in this population, suggesting a need for further research into young spousal grief. Young bereaved spouses may lack flexibility in reconstructing their view of the world as the death may invalidate their previously held world beliefs.

The effect of self-observation on children's problem solving.

The effects of self-observation on children's problem solving were investigated. Children (N = 124) aged 6-8 years attempted to solve the 3-disc Tower of Hanoi problem. After pretesting, children were grouped into those who (a) practiced solving the(c) observed problem independently, (b) received instruction on the most efficient solution, a videotape recording of their previous attempt, and (d) served as a control. Subsequently, children were immediately tested on the 3-disc problem and a more difficult 4-disc problem. They were tested again 1 week later. Performance was most improved for children inwere maintained the practice and video conditions on the 4-disc problem. Improvements over the 1-week interval. Unique characteristics of video self-observation are discussed.
