What exactly is a yait anyway: The role of semantics in orthographic learning

This study investigated whether semantic information presented along with novel printed nonwords facilitates orthographic learning and examined predictors of individual differences in this important literacy skill. A sample of 35 fourth graders was tested on a variety of language and literacy tests, and participants were then exposed to 10 target nonwords, 5 of which were presented with semantic information. Children were tested 1 and 4 days later on their ability to correctly recognize and spell the target nonwords. Results revealed a significant main effect on the recognition task, where items presented with semantic information were identified correctly more often than were words presented in isolation. No significant effect of training condition was found for the spelling posttests. Furthermore, multiple regression analyses revealed that both phonological and semantic factors were significant predictors of orthographic learning. The findings support the view that orthographic learning, as measured through visual recognition, involves the integration of phonological, orthographic, and semantic representations.     

Reduced misinformation effects following saccadic bilateral eye movements

The effects of saccadic bilateral (horizontal) eye movements on memory for a visual event narrative were investigated. In the study phase, participants were exposed to a set of pictures accompanied by a verbal commentary describing the events depicted in the pictures. Next, the participants were asked either misleading or control questions about the depicted event and were then asked to engage in 30s of bilateral vs. vertical vs. no eye movements. Finally, recognition memory was tested using the remember-know procedure. It was found that bilateral eye movements increased true memory for the event, increased recollection, and decreased the magnitude of the misinformation effect. The findings are discussed in terms of source monitoring, dual-process theories of memory and the potential neural foundations of such effects.     

Critical Psychology: What It Is and What It Is Not

Critical psychology alerts us to the limitations of mainstream research in the discipline, and it promises to put 'social' issues on the agenda in the whole of psychology. A starting point of the stance of critical psychological research is that the claims that psychologists make about human beings often seem to vanish almost as quickly as they are discovered. People, a group or culture do not behave or think like the model would predict, and, more importantly, we find that our awareness, our reflection on a process described by a psychologist changes that process. It is in the nature of human nature to change, to change as different linguistic resources, social practices, and representations of the self become available, and for human nature to change itself as people reflect on who they are and who they may become. That means that any attempt to fix us in place must fail. But it will only fail in such a way that something productive emerges from it if we do something different, and one place to do something different is in psychology. We need to step back and look at the images of the self, mind and behaviour that psychologists have produced, the types of practices they engage in, and the power those practices, those 'technologies of the self' have to set limits on change. When we appreciate this, we can start to look at what psychologists might do instead as part of a genuinely critical approach.     

Emotional availability and psychosocial correlates among mothers in substance‐abuse treatment and their young infants

Emotional availability (EA) was investigated among low‐income mothers enrolled in substance‐abuse treatment and their young infants (n = 21) compared with a demographically matched group of mother–infant pairs who, by self‐report, were not at risk for substance abuse (n = 27). The mother–infant dyads in the treatment group generally demonstrated poorer EA functioning than those in the comparison group, but few differences between the groups on individual dimensions of EA were significant. This finding was notable considering that mothers in treatment reported significantly higher levels of depressive symptoms and psychological stress. Treatment effects may have buffered the negative impact of depression and psychological stress on mothers' EA scores. The clinical implications of the findings are discussed as they relate to substance‐abuse‐treatment services for pregnant and parenting women.     

TEACHING THE PSYCHOLOGY OF WOMEN COURSES IN ANOTHER DISCIPLINE

A survey of course titles in African American Studies departments and programs was conducted to examine the course offerings on the psychology of women, the psychology of African American women, and other areas of psychology as well as courses on gender from other disciplines. A total of 82 programs or departments of African American Studies and 182 courses were listed. The course discipline was stated in the majority of courses, with psychology having the most courses. Only a small percentage of the psychology courses listed gender in addition to race in the title. Of those courses listed in psychology, the majority were in social, developmental, or clinical psychology. The disciplines of English, sociology, history, and political science had listings of courses with both gender and race titles. This small survey indicates that the psychology of women has not had much influence on the curriculum of African American Studies. Possible reasons for this are discussed, as are solutions to this problem.     

Studies on retrograde and anterograde amnesia of olfactory memory after denervation of the hippocampus by entorhinal cortex lesions

The effect of hippocampal denervation on olfactory memory in rats was tested after interrupting the lateral olfactory tract projections at the level of the entorhinal cortex. When lesioned animals were trained to learn new odors, they showed no evidence of retention 3 h after acquisition. These results confirm earlier data on rapid forgetting in rats after hippocampal deafferentation and are in parallel to the anterograde amnesia typically found in humans with hippocampal damage. On the other hand, preoperatively learned information was minimally impaired after hippocampal deafferentation even if it was acquired within less than 1 h before the lesion. This finding differs from reports on humans as well as monkeys with hippocampal damage where memories formed during a critical time span of months or even years before the lesion are found to be impaired. This may suggest that the consolidation process in humans and rodents has different time scales or that the roles of the human and the rat hippocampal structure in memory formation are somewhat different.     

Apparent duration and spatial structure.

In three experiments, we investigated the relative perceived duration of a full bandwidth image and a set of high- and lowpass filtered images of a scene, briefly presented on a visual display unit. In Experiment 1, the various images were compared with each other, using a paired comparison method. All images were presented for 40 msec, and observers were asked to judge which of each pair of images had the longest duration. The results showed that images containing a wide spatial frequency bandwidth were judged to be of longer duration than were images of a narrower bandwidth, regardless of whether the latter were high- or lowpass filtered. In Experiment 2, a 40-msec presentation of each of the images was compared with a presentation of a probe that was 20, 40, 60, or 80 msec in duration. Observers again judged which of each pair of images had the longest duration. The results were very similar to those of Experiment 1, with wide bandwidth images being judged to be of longer duration than were narrow bandwidth images. In Experiment 3, instead of comparing the various filtered versions of the image with each other, we attempted to obtain a direct measure of perceived duration by comparing a flashing LED to a 40-msec flash of a subset of the images used in the previous experiments. The observers' task was to adjust the duration of the LED flash to match the perceived duration of each image.(ABSTRACT TRUNCATED AT 250 WORDS)     

Effects of fantasy contexts on children's learning and motivation: making learning more fun.

Two studies examined the effects of embedding instructional materials in relevant fantasy contexts on children's motivation and learning. In Study 1, Ss showed marked preferences for computer-based educational programs that involved fantasy elements. In Study 2, Ss worked with these programs for 5 hr. One program presented purely abstract problems. Others presented identical problems within fantasy contexts. Some Ss chose among 3 fantasies; others were assigned identical fantasies. Tests on the material occurred before, immediately after, and 2 weeks after the experimental sessions. Ss showed significantly greater learning and transfer in the fantasy than in the no-fantasy conditions. Having a choice of fantasies made no difference. Motivational and individualization strategies for enhancing interest and promoting learning are discussed.
