Sex differences in cognition in healthy elderly individuals

ABSTRACT

Sex differences in patterns of cognitive test performance have been attributed to factors, such as sex hormones or sexual dimorphisms in brain structure, that change with normal aging. The current study examined sex differences in patterns of cognitive test performance in healthy elderly individuals. Cognitive test scores of 957 men and women (age 67–89), matched for overall level of cognitive test performance, age, education, and depression scale score, were compared. Men and women were indistinguishable on tests of auditory divided attention, category fluency, and executive functioning. In contrast, women performed better than men on tests of psychomotor speed and verbal learning and memory, whereas men outperformed women on tests of visuoconstruction and visual perception. Our finding that the pattern of sex differences in cognition observed in young adults is observed in old age has implications for future studies of both healthy elderly individuals and of those with cognitive disorders.     

Protective Factors for Subjective Well-being in Chinese Older Adults: The Roles of Resources and Activity

The purpose of current study was to examine the relationships between resources, activity, and subjective well-being in later life. Using a national sample (N = 3,795) of older adults randomly selected from major Chinese mainland cities, we integrated the constructs of resources and activity into a structural model of subjective well-being. In the model, the three key resources, health, economic status and family relations, were specified as having direct effects on both activity and subjective well-being. Additionally, activity was specified as having a direct effect on subjective well-being. AMOS software was used to test and compare the goodness of fit of various models. The data had a satisfactory fit to the model (GFI = 0.980, NNFI = 0.959, CFI = 0.973, RMSEA = 0.049), indicating that the three resources had significant contributions to subjective well-being. Comparisons using several nested models also suggested that family relations had a stronger effect than health and economic status on subjective well-being. Further, activity was a partial mediator in the relationships between resources and subjective well-being.     

Influence of Training in Artistic Skills on Mental Imaging Capacity

ABSTRACT

Artistic creation often involves the use of mental images. This investigation examined the influence of training in artistic skills on mental imaging capacity in a sample of 126 subjects aged between 18 and 23 years. First- and 5th-year fine arts students were compared with regard to their performance in 2 imaging capacity tests (the Visual Elaboration Scale and the Vividness of Visual Imagery Test) and 3 tests of drawing involving spatial representation, transformation of spatial relations, and memory. The students who had undergone a longer period of artistic training performed significantly better on all 5 tests, and all drawing tasks scores correlated with each other. These results indicate that artistic training may enhance imaging capacity.     

Vividness and Control of Mental Imagery and the Components of In-Depth Drawing

The aim of this study was to examine the associations of control and vividness of mental imagery on performance in several components of in-depth drawing in a sample of fine arts undergraduates. The sample consisted of 56 second-year undergraduates (44 women and 12 men, mean age = 21.18 years) from the Fine Arts Faculty of Vigo University, Pontevedra, Spain. Participants were required to undertake a plastic art assignment focusing on the pictorial representation of space. Participants scoring high on the image control test obtained higher scores on the spatial analysis and in the formal construction of a work than participants with poor image control. Further research involving spatial image performance tests and mental image rotation tests is proposed.     

On the Role of Vertical Texture Cues in Height Perception

When people judge height from the top looking down they tend to overestimate vertical distance. Initial findings suggest that this perceptual bias may be in part due to the experienced fear of falling. However, previous studies did not control for potentially relevant optical invariants, especially vertical texture gradient cues, that may inform such perceptual judgments. In this study, we examined to what degree texture gradient cues may account for the perceptual bias in height perception. To this end, in 2 different conditions in which vertical texture gradient cues were either present or absent, participants provided distance and size judgments from an elevated position (5.68 m) and from the ground. Results revealed a systematic overestimation of vertical extent and object size when judged from a height. Yet, the absence or presence of texture gradient cues did not differentially influence these judgments. Finally, although fear levels were reported to be larger at the elevated position than on the ground, fear levels did not correlate with the perceptual bias, thereby demanding further research into the mechanisms underlying the perceptual bias in height perception.     

Young Tennis Players’ Competitive Task Involvement and Performance: The Role of Goal Orientations,Contextual Motivational Climate,And Coach-Initiated Motivational Climate

The purpose of this study was to examine the role of situational and dispositional factors in contributing to competitive task involvement and performance in young tennis players. One hundred fifty-one adolescent tennis players and their coaches participated in the study. Participants responded to instruments measuring pre-game dispositional goal orientations and perceptions of the motivational climate and post-game task involvement in the competition by assessing concentration, loss of self-consciousness, and autotelic experience, perceptions of coach-initiated motivational climate in competition, and self-evaluation of game performance. In addition, coaches evaluated the players’ performance. Results showed that task involvement was predicted by players’ perceptions of a coach-initiated learning motivational climate in competition. Loss of self-consciousness was predicted by the players’ perceptions of a coach-initiated performance climate in competition. Finally, coaches’ and players’ assessment of performance were predicted by autotelic experience, concentration, and by perception of coach-initiated learning and performance orientation in competition.     

Of Coals and Eskimos: Reply to Commentary

I first point out that there are similarities between the Fiscalini and me, and then I try to clarify some differences. Fiscalini suggests that I may be “inadvertently taking coals to Newcastle,” in arguing in favor of a well-known concept. Coming from a Freudian orthodox background, I have learned to substantiate every step of my reasoning on nonorthodox concepts. This sort of clarification may be useful, even for those who share my point of view.

One misunderstanding is that Fiscalini classifies me as an advocate of participant observation, whereas I identify with coparticipation. After suggesting some possible explanation for this difference, I develop some of my own ideas about psychoanalysis considered in terms of analogical hermeneutics, the paradox of being both individual and communal at the same time, and the need to include the social and political context in the analytic inquiry, and transcend the pseudo-opposition between interpretation and experience.     

Child’s Personality and Perception of Parental Relationship as Correlates of Optimal Experience

The study was designed to assess the influence of child’s personality and perception of parental relationship on children’s optimal experiences. We proposed functional and dysfunctional models to analyze the increase or the decrease of the children’s flow experience. The sample of this study included 909 middle class children, aged 9–12 (M = 11.02, SD = 1.08), both sexes, from Argentina. When we analysed the psychological factors that could be related to the flow state in childhood, we found out that the child’s perception of a functional parental relationship, in which there is either acceptance or moderate control, indirectly affects the flow experience, through child’s personality—extraversion, openness to experience, and conscientiousness. Functional personality traits have an important positive effect on optimal experience when they are considered as a unit. In the dysfunctional model of flow, the results showed that the child’s perception of parental pathological control had an important positive effect on neuroticism and –through this—a negative effect on flow. The child’s perception of parental negligence did not have a significant effect on neuroticism; however, neuroticism still maintained its negative effect on flow.     

Student Development and Support using a Logotherapeutic Approach

This study reports on participants' meaning-centred experiences and perspectives after attending a logotherapy-based student development and support programme. Thirteen students who were enrolled in the first year of the academic programme, in health science programme at a South Africa university, were participants. Qualitative inquiry was used for the data collection and analysis. Findings suggest that a meaning-centred approach may prove to be beneficial for first year university students.
