The impact of consonant clusters on preschool children''s phonemic awareness: A comparison between readers and nonreaders

Preschool children's ability to segment and blend real words and nonsense words, with and without consonant clusters was investigated in two experiments. In the first experiment, preschool children's ability to segment real words into phonemes was examined. Readers performed better than nonreaders on a phoneme counting task and words containing consonant clusters were harder to segment compared to words without consonant clusters. In experiment two, the ability to segment and blend nonsense words was investigated. Nonreaders had significantly more difficulty with nonsense words compared to readers in both a phoneme synthesis and a phoneme analysis task. A two-way interaction between reading level and word type showed that nonsense words containing consonant clusters were particularly difficult for nonreaders. The results were discussed in relation to theories suggesting that syllables consist of an onset and a rime.     

Risk perception and the location of a repository for spent nuclear fuel

This study investigates lay people's reactions to a repository for nuclear waste. Risk perception is seen as a complex concept, comprising both affective and cognitive components. Attitude towards nuclear power and trust in experts and authorities had a substantial impact on risk perception, while personal knowledge about nuclear waste disposal had no effect. Thus, the more positive one's attitude towards nuclear power is and the more trust one has in experts and authorities, the lower one's risk perception is. Also, reactions were expected to vary with distance between the home district and the location of a repository. These variations differed in nature for people with alternative levels of risk judgement. The distance between the home and a repository affected approval of the proposed site. Distance between home and repository also had an effect on risk feelings and somewhat less on beliefs about consequences. Estimated total risk was directly mediated by beliefs about consequences, but even more so by risk feelings. With regard to risk, one can conclude that it is important to make a distinction between an emotional and a cognitive component of risk perception.     

Processing of information about location during locomotion: Effects of a concurrent task and locomotion patterns

How maintenance of orientation during locomotion in unfamiliar environments is accomplished was investigated by having subjects walk behind a moving light line (1.12 m/sec) in a dark room and, from a stopping point, numerically estimate direction and distance to the starting point. Two linear distances (5.0–8.4 m) and the angle of direction change (45, 90, and 135 deg) were orthogonally varied as 12 locomotion patterns. Eight high-school students were assigned to each of three conditions, two in which the starting point was invisible, one in which it was visible. In one of the former conditions the subjects counted backwards rapidly during walking. Lower accuracy and longer latency times were found in the counting condition whilst the other two conditions differed only slightly. The results suggested that accurate maintenance of orientation is achieved by recurrent encoding, coordination and decoding of information about direction change and locomotion distance, processes which demand central processing capacity and therefore are interfered with by a concurrent task.     

The relative impact of workplace bullying as a social stressor at work

Hauge, L. J., Skogstad, A. & Einarsen, S. (2010). The relative impact of workplace bullying as a social stressor at work. Scandinavian Journal of Psychology, 51, 426–433. Exposure to workplace bullying has been argued to be a severe social stressor and a more crippling and devastating problem for affected individuals than the effects of all other work‐related stressors put together. However, few studies have explicitly investigated this assumption. In a representative sample of the Norwegian working population, the present study investigated the relative contribution of workplace bullying as a predictor of individual and organizational related outcomes after controlling for the well‐documented job stressors of job demands, decision authority, role ambiguity and role conflict. Bullying was found to be a significant predictor of all the outcomes included, showing a substantial relative contribution in relation to anxiety and depression, while for job satisfaction, turnover intention and absenteeism, more modest relative contributions were identified. Workplace bullying is indeed a potent social stressor with consequences similar to, or even more severe than, the effects of other stressors frequently encountered within organizations. Thus, the finding that bullying has a considerable effect on exposed individuals also when controlling for the effects of other job stressors demonstrates bullying as a serious problem at workplaces that needs to be actively prevented and managed in its own right.     

Effects of sleep deprivation on voluntarily controlled reversal rate of ambiguous figures

Abstract.— The effects of sleep deprivation (SD) on the reversal rate of the Necker cube and Rubin's Vase-Faces were studied both with instructions to maximize and to minimize the rate. Three viewing conditions were used: Free eye movements, eyes on a fixation point and reversals of an after-image of the figure. SD was found to increase the rate under minimizing instructions and to decrease the rate under maximizing instructions. The results were interpreted in terms of an accelerated satiation process and an impairment of the attentional control.     

Adult attachment style,interpersonal communication competence,and social support

Individuals with a more secure attachment style report having larger and more satisfying social support networks Individuals with a more anxious or a more avoidant attachment style, by contrast, report having smaller and less satisfying support networks The present study examined the role of interpersonal communication competence (ICC) as a possible mediator of the association between attachment and social support in a sample of college undergraduates Strong support was found for the described model. Mediational analyses revealed that global deficits in ICC could account for the smaller social support network sizes and lower levels of satisfaction among both more anxiously attached and more avoidantly attached individuals. In addition, subsequent analyses examining specific dimensions of ICC revealed that the lower support satisfaction among more anxious individuals could be uniquely accounted for by a lack of assertiveness in social interactions For more avoidantly attached individuals, smaller network sizes could be uniquely accounted for by lower levels of self‐disclosure, and less support satisfaction could be uniquely accounted for by a lack of assertiveness in addition to lower levels of self‐disclosure. The implications of these findings and suggestions for future research are discussed.     

Preoptic lesions, sexual behavior, and spontaneous ejaculation in the rat

Abstract.— A possible relation between sexual behavior and spontaneous ejaculation was studied in the male rat. Electrolytic lesions in the preoptic area completely abolished sexual behavior without affecting the frequency of spontaneous ejaculation. It is therefore suggested that this latter process is controlled independently of sexual behavior and sexual excitability.     

Road-sign utility as judged by drivers with different amounts of driving experience

This study starts from the hypothesis that sign perception depends on the motivational valences of signs. Two groups of drivers with different amounts of driving experience rated Swedish road signs on dimensions assumed to indicate perceived sign utility. The ratings were performed against a scenario that included traffic officials' intentions to simplify the sign system. One dimension was amount of reduction in frequency of occurrence; subjects indicated percentages of reduction they believed to be reasonable. A second dimension was appropriateness of complete elimination of a sign from the traffic environment; subjects rated the degree to which elimination was reasonable. Subjective frequency of sign occurrence was rated last. Construct validation procedures showed strong correlations between reduction and elimination ratings only for the higher-experience group. Contrary to expectation, both groups showed the same high level of positive attitudes toward all signs. As expected, frequency was a judgmental base for utility, though weakly, except for permissive signs. It was more extensively related to utility for the higher-experience group, particularly for percentage ratings. Curvilinear relationships obtained between frequency and utility for permissive and road guidance signs.     

Co‐Witness Influence on Children's Memory Reports: The Difference is in the Details1

This study examined the effect of social influence on children's witness reports, with respect to a number of details varying in centrality. Children (N = 115; age = 10 years, 4 months to 13 years, 8 months) were interviewed about a personally experienced event. Half of the children were interviewed together with a confederate who answered the interview questions before the child did, while the other half were interviewed alone. Children were influenced by the confederate's answers to withhold some critical details observed (omission errors), but not to add details not observed (commission errors). When the children were asked to follow up on their reports, truthful reports contained more information than did false reports.     

Is the truth in the details? Extended narratives help distinguishing false “memories” from false “reports”

The present study examined the effects of fantasy proneness on false "reports" and false "memories", of existent and non-existent footage of a public event. We predicted that highly fantasy prone individuals would be more likely to stand by their initial claim of having seen a film of the event than low fantasy prone participants when prompted for more details about their experiences. Eighty creative arts students and 80 other students were asked whether they had seen CCTV footage preceding the attack on Swedish foreign minister Anna Lindh up to, and including, non-existent footage of the actual moment of the attack. If affirmative, they were probed for extended narratives of what they claimed to have seen. Overall, 64% of participants provided a false "report" by answering yes to the initial question. Of these, 30% provided no explicit details of the attack, and a further 15% retracted their initial answer in their narratives. This left 19% of the sample who appeared to have false "memories" because they provided explicit details of the actual moment of the attack. Women scored higher than men and art students scored higher than other students on fantasy proneness, but there was no effect on levels of false reporting or false "memory". Memories were rated more vivid and clear for existent compared to non-existent aspects of the event. In sum, these data suggest a more complex relationship between memory distortions and fantasy proneness than previously observed.
