Perceived Child Rearing Practices as Predictors of University Students' Satisfaction with their Sexual Relationships

The aim of this study was to determine the effects that perceived child-rearing practices have on the sexually intimate relationship satisfaction of a sample of 130 male (n=62) and female (n=68) fourth year South African university students. Participants completed the Parenting Bonding Instrument (Parker, Tupling, & Brown, 1979), Stevens Relationship Questionnaire (Stevens & Stevens, 1994) and the Sexual Knowledge Questionnaire (Louw, 2000) to measure perceived parent-child attachment, respondents' sexually intimate relationships and level of sex education. Hierarchical regression analysis was conducted to investigate the influence of perceived child rearing practices on sexually intimate relationship satisfaction. The results suggest that parent-child attachment explained a significant percentage of the variance in intimate relationship in young adulthood.     

Report on work in progress: “Towards a new science of the human”

A multidisciplinary and global study of the evolutionary process of the universe in general and mankind in particular is proposed, drawing from both modern science, approached by taking into consideration its various interdependent aspects; and the study of western and eastern ancient traditions, which prove to have a common foundation that is the comprehension and the control of the evolutionary process itself.

Such a study will lead to the compilation of a “Corpus Unus” of the new science of the human, a science which does not belong to a race, a culture or an age, but is specific to the human being as such.

Such a science will imply the exploration of mankind and of the evolutionary process, and applying the results in a pragmatic way to the betterment of human beings, society, and universe.     

Left or right carotid endarterectomy in patients with atherosclerotic disease: ipsilateral effects on cognition?

We evaluated hemispheric functions ipsilateral to the side of carotid endarterectomy (CEA) in patients with a severe stenosis in the left or right carotid artery. Assessments took place 1 day before and 3 months after CEA. Only right-handed males were included. Nineteen patients underwent surgery of the left carotid artery and 17 of the right. Valid instruments for hemispheric function were included, such as verbal dichotic listening, finger tapping, and a lateralised test for motor planning. Results showed that, preoperatively, patients had lower scores compared to norms on the laterality tests, and on a visuoconstructive test. There was no evidence of ipsilateral improvement related to side of surgery. Left ear dichotic listening improved, which was seen in both left and right surgery groups. Also in both groups, left- and right-hand movement speed in the motor planning test decreased. Conclusion is that beneficial ipsilateral cognitive change after CEA in patients with severe stenosis in one of the carotid arteries may not be demonstrated, even if valid instruments for hemispheric function are included.     

Differentiation at higher levels of cognitive ability: evidence from the United States

Most psychologists and educators assume that intelligence is a linear construct, meaning that smart people simply have more intelligence than their less gifted peers. Likewise, individuals with mental retardation are thought to have less intelligence. In contrast to this widely accepted belief, the authors posed an alternative hypothesis--that intelligence is qualitatively different in various populations. Using factor analysis of a standardization sample of the Woodcock-Johnson Test of Cognitive Ability (R. W. Woodcock & M. B. Johnson, 1989), the authors examined the nature of intellect across ability. Results indicated that the amount of variance attributable to Spearman's g declined as measured intellectual ability increased.     

A novel approach to assessing achievement goals in the context of the 2 x 2 framework: identifying distinct profiles of individuals with different dominant achievement goals

In two studies, individuals' dominant achievement goals were assessed using a new, simple, and conceptually precise measure based on Elliot and McGregor's (2001) 2 x 2 framework. Next, the four groups were compared in terms of achievement-relevant variables, including need for achievement, perfectionism, perceived competence, interest, and graded performance. As expected, a very high percentage (approximately 85%) of people indicated they had a dominant achievement goal. Furthermore, the results suggest that individuals with different dominant achievement goals have clear, distinct profiles that can be characterized as positively valenced (mastery-approach), both positively and negatively valenced (performance-approach), negatively valenced (performance-avoidance), or neither positively nor negatively valenced (mastery-avoidance).     

Cognitive and social-emotional development of children in different preschool environments

62 English-speaking preschool children were divided into three groups, a Montessori group (n = 21), a traditional preschool group (n = 21), and a homestaying group (n = 20) to compare their relative cognitive and social-emotional development. Significant differences in favour of the school groups were found for vocabulary, language comprehension, ability to judge the correctness of figural stimuli, visual memory, and perceptual organization. No differences were found for social-emotional development, and no relationship existed between type of preschool and level of development.     

Learning and retrieval rate of words presented auditorily and visually

Mode of presentation (visual or auditory) of a multitrial free recall test is stressed as an important factor in improving the diagnosis of certain neurological patients. For further use in neuropsychological research, an experiment was carried out using normal subjects, in which the effects of presentation mode and order of modality were investigated. There were no differential effects of these variables on several parameters, such as the number of words recalled and the learning curve. The time needed for the responses in immediate recall was the same in both auditory and visual conditions. In delayed recall, however, the interresponse times were significantly shorter when words had been presented auditorily than when presented visually. The results are discussed in light of further application in the field of neuropsychology.     

Reducing color-color interference by optimizing selection for action

Color-color interference refers to the finding that the naming of a target color is hampered by the simultaneous presentation of an incongruent distractor color somewhere else in the visual field. This interference effect has been attributed to an imperfect input selection (selection-for-processing). We test an alternative account in which it is assumed that (a) target and distractor are identified in parallel without mutual interference, (b) the identified target color has to be selected to control the naming response (selection-for-action), and (c) this selection process takes more time and is less accurate in the incongruent condition than in the control conditions. Experiment 1 shows that color-color interference is obtained when a target color, presented at the point of fixation, is flanked by incongruent colors. In Experiments 2 and 3, the central target position is indicated by an additional exogenous selection cue. The results show that an abrupt-onset cue, presented at the central target position 160 ms after the onset of the target and distractors, reduces the interference effect. This finding is interpreted as supporting evidence for a selection-for-action account of color-color interference.
