A case of prosopagnosia with some preserved covert remembrance of familiar faces

This paper presents the detailed analysis of a case of prosopagnosia in a 54-year-old male farmer following bioccipital vascular disease. In-depth clinical investigations confirmed the diagnosis of prosopagnosia and revealed the absence of any associated defect, except for a slight aspecific disturbance of the short-term memory. Further study of this case indicated that the trouble was not concerned with the class of complex visual stimuli, was not even concerned with facial expressions or unknown faces, was not a perceptual defect, but was related mainly to the operation of individualization. The memory hypothesis was thus retained and supported. Moreover, exploration of the difficulty indicated that the deficiency was limited to defective access to conscious information concerning faces and information associated with these faces (name, context, etc.), effectively stored in memory.     

COLLEGE WOMEN'S AGGRESSION IN RELATIONSHIPS:THE ROLE OF CHILDHOOD AND ADOLESCENT VICTIMIZATION

Despite growing evidence suggesting that women engage in verbal and physical dating aggression, there is a dearth of research examining the predictors of women's engagement in these behaviors. Utilizing a college sample, the purpose of the current study was to explore women's perpetration of dating aggression within the context of victimization experiences. Women ( N  = 374) completed surveys at the beginning and end of a 10-week academic quarter for course credit. Results from two retrospective regression analyses (all Time 1 variables) suggested that (1) paternal physical abuse and adolescent/adulthood verbal victimization predicted women's reports of verbal perpetration and (2) childhood sexual abuse, adolescent/adulthood verbal victimization, adolescent/adulthood physical victimization, and adolescent/adulthood verbal perpetration predicted women's reports of physical perpetration. Results from the two prospective, longitudinal regression analyses suggested that (1) verbal perpetration (as measured at Time 1) and verbal victimization over the interim predicted women's reports of verbal perpetration over the interim and (2) physical perpetration (as measured at Time 1), verbal perpetration over the interim, and physical victimization over the interim predicted women's reports of physical perpetration over the interim. These data suggest the importance of considering previous victimization experiences, mutual partner aggression, and a history of aggressive behaviors when examining women's use of aggression in dating relationships.     

Do examples of failure effectively prepare students for learning from subsequent instruction?

Studies on the productive failure (PF) approach have demonstrated that attempting to solve a problem prepares students more effectively for later instruction compared to observing failed problem-solving attempts prior to instruction. However, the examples of failure used in these studies did not display the problem-solving-and-failing process, which may have limited the preparatory effects. In this quasi-experiment, we investigated whether observing someone else engaging in problem solving can prepare students for instruction, and whether examples that show the problem-solving-and -failing process are more effective than those that only show the outcome of this process. We also explored whether the perceived model–observer similarity had an impact on the effectiveness of observing examples of failure. The results showed that observing examples effectively prepares students for learning from instruction. However, observing the model's problem-solving-and-failing process did not prepare students more effectively than merely looking at the outcome. Studying examples were more effective if model–observer similarity was high.
