Attentional blink differences between adolescent dyslexic and normal readers

The goal of this study was to evaluate the possibility that dyslexic individuals require more working memory resources than normal readers to shift attention from stimulus to stimulus. To test this hypothesis, normal and dyslexic adolescents participated in a Rapid Serial Visual Presentation experiment (Raymond, Shapiro, & Arnell, 1992). Surprisingly, the result showed that the participants with dyslexia produced a shallower attentional blink than normal controls. This result may be interpreted as showing differences in the way the two groups encode information in episodic memory. They also fit in a cascade-effect perspective of developmental dyslexia.     

Spatial location judgments: a cross-national comparison of estimation bias in subjective North American geography

We examined alternate explanations for distortions in the subjective representation of North American geography. One explanation, based on physical proximity, predicts that bias in location estimates should increase with the distance from a participant's home city or region. An alternative is that biases arise from combining accurate and inaccurate beliefs about the cities and the superordinate regions to which they belong, including beliefs that may have social or cultural origins. To distinguish these, Canadians from Alberta and Americans from Texas judged the latitudes of cities in Canada, the U.S., and Mexico. The Texans' estimates of Mexican locations were 16" (approximately 1,120 miles) more biased than their estimates of Canadian locations that were actually about 840 miles farther away. This finding eliminates proximity as a primary source of geographic biases and underscores the role of categorical beliefs as an important source of biased judgments.     

A program for psychological education: Some preliminary issues

The recent interest in personal and/or psychological education as an objective for school programs has created the necessity for the development of a careful theoretical framework. This paper examines the current status of theory vis à vis personal education and suggests a number of major issues for consideration. A toxonomy for personal education has yet to be developed. Concepts of emotions as “bad”, pathological, and private need revision. Also, it is suggested that adolescence as a stage of development comprehends a special set of theoretical questions which cannot be begged. Particular attention is directed at implications derived from a developmental framework suggested by Piaget in cognitive areas and by Kohlberg in moral growth. Such a framework connotes educational goals as objectives which avoid the problems inherent in other current theoretical frameworks.     

Personality and family functioning in families of depressed patients

In this cross-sectional study, the authors attempted to identify correlates of family functioning in 86 couples with a depressed member during the acute phase of the patient's depression. Demographic variables, psychiatric status, and personality traits of both the patient and spouse were investigated as potential predictors of family functioning. Regression analyses indicated that lower levels of personality pathology in the patient, higher levels of patient conscientiousness, and less psychological distress in the spouse were associated with healthier family functioning. Future research implications and clinical importance of these findings are discussed.     

Couples' shared participation in novel and arousing activities and experienced relationship quality

Using a newspaper questionnaire, a door-to-door survey, and 3 laboratory experiments, the authors examined a proposed effect of shared participation in novel and arousing activities on experienced relationship quality. The questionnaire and survey studies found predicted correlations of reported shared "exciting" activities and relationship satisfaction plus their predicted mediation by relationship boredom. In all 3 experiments, the authors found predicted greater increases in experienced relationship quality from before to after participating together in a 7-min novel and arousing (vs. a more mundane) task. Comparison with a no-activity control showed the effect was due to the novel-arousing task. The same effect was found on ratings of videotaped discussions before and after the experimental task. Finally, all results remained after controlling for relationship social desirability. Results bear on general issues of boredom and excitement in relationships and the role of such processes in understanding the typical early decline of relationship quality after the honeymoon period.     

Disruptive Individual Experiences Create Lifetime Periods: a Study of Autobiographical Memory in Persons with Spinal Cord Injury

Previous research showed that transitional events causing catastrophic and long‐lasting changes in group of people's lives (e.g., wars) create autobiographical periods. We investigated whether spinal cord injury (SCI), an involuntary and externally driven disruptive event at the individual level, would also act as a temporal landmark and spawn personal periods and whether these periods have comparable functions and temporal characteristics as those generated at the group level. Thirteen volunteers with SCI recalled a cue‐related autobiographical event for each of 22 cue words. Later, participants thought aloud when dating each event. We used the prevalence of injury‐related references as an index of the degree to which spinal cord injury affects people's lives. We found frequent references to injury for the period neighboring injury event. Unexpectedly, we also found that SCI resulted in post‐injury decrease in event memory. Results imply that SCI provides a temporal landmark and creates an autobiographical period.Copyright © 2015 John Wiley & Sons, Ltd.     

Contrasting accounts of direction and shape perception in short-range motion: Counterchange compared with motion energy detection

It has long been thought (e.g., Cavanagh & Mather, 1989) that first-order motion-energy extraction via space-time comparator-type models (e.g., the elaborated Reichardt detector) is sufficient to account for human performance in the short-range motion paradigm (Braddick, 1974), including the perception of reverse-phi motion when the luminance polarity of the visual elements is inverted during successive frames. Human observers’ ability to discriminate motion direction and use coherent motion information to segregate a region of a random cinematogram and determine its shape was tested; they performed better in the same-, as compared with the inverted-, polarity condition. Computational analyses of short-range motion perception based on the elaborated Reichardt motion energy detector (van Santen & Sperling, 1985) predict, incorrectly, that symmetrical results will be obtained for the same- and inverted-polarity conditions. In contrast, the counterchange detector (Hock, Schöner, & Gilroy, 2009) predicts an asymmetry quite similar to that of human observers in both motion direction and shape discrimination. The further advantage of counterchange, as compared with motion energy, detection for the perception of spatial shape- and depth-from-motion is discussed.
