Psychosocial concomitants of loneliness among students of Cape Verde and Portugal

This research is an examination of the relationship between loneliness and a number of psychosocial variables (e.g., affective state, cultural issues, gender, age) among adolescents and young adults from Cape Verde and Portugal. Two studies are presented. The participants in the first study were 285 adolescents from Cape Verde and 202 from Portugal, and in the second study there were 134 college students from Cape Verde and 112 from Portugal. The following instruments were administered to all the participants in both studies: The Revised UCLA Loneliness Scale (D. Russell, L. Peplau, & C. Cutrona, 1980), the Neuroticism Scale (J. Barros, 1999), the Optimism Scale (J. Barros, 1998), the Social Anxiety subscale (A. Fenigstein, M. Scheier, & A. Buss, 1975), and the Satisfaction With Life Scale (E. Diener, R. Emmons, R. Larsen, & S. Griffin, 1985). No ethnic or gender differences were found for loneliness between the two groups. For both groups, the most prominent predictors of loneliness were neuroticism and dissatisfaction with life. However, as expected, the adolescent group recorded higher scores for loneliness than did the college students.     

Preliminary identification of nonlinear correlations for spatial tests and reaction-time tasks

Scores on three spatial tests (mental rotation, embedded figures, and gestalt completion) were significantly correlated with four same-different reaction-time tasks in a sample of 48 female university students. Scores on the Vandenberg-Kuse mental rotation test correlated best with a one-different-all-different task, embedded figures with a one-different-all-same task, and the gestalt completion with a one-same-all-same task, suggesting that the strategies subjects employ for each spatial test are similar to the strategies they use in each of the same-different tasks with which their scores correlate best. Present results support the position that stronger correlations than previously noted between scores on spatial tests and reaction-time tasks are observed when matching the tests and tasks in terms of hypothesized underlying processes.     

Environmental influences on perceptual and motor skills of children from immigrant Ethiopian families

The purpose of this study was to examine environmental influences on perceptual and motor skills of children from immigrant Ethiopian families in Israel in comparison with those of Israeli-born children. The subjects were divided into groups based on age (6- to 8-yr.-olds and 10- to 12-yr.-olds) and length of time in Israel. The results of this study show that the perceptual and motor performance of 6- to 8-yr.-old, less recent Ethiopian immigrants is similar to that of the recent Ethiopian immigrants of the same age. A difference exists between those two groups and the Israeli-born children of the same age. In the 10- to 12-yr.-old age group, there is a marked difference between the performance of the two groups of Ethiopian immigrants. The difference between the less recent immigrants and the Israeli-born children is smaller for most tasks; however, the less recent immigrants' performance is still poorer than that of the Israeli children. These results are compatible with those of other studies describing the difficulties encountered by children who had not studied in formal educational settings and those who have had that experience.     

Factors affecting metamotivational reversals during motor task performance

Reversal theory proposes that the individual's psychological state constantly switches between metamotivational state pairs (such as Apter's 1982 telic-paratelic pair). Three factors are thought to affect reversals: frustration, contingent event, and satiation. Only a few studies have directly investigated these factors in sports contexts, and evidence is needed to assess support for these factors. In a laboratory setting, 24 participants performed a telic and a paratelic version of a dart-throwing task for 10 min. Participants were free to change from one task version to another as they wished, and reasons for any task changes were solicited. Task changes, indicative of reversals, were observed in 11 participants, and these were reported as due to satiation or frustration but not to contingent events. These findings may inform the structure of sessions on skill development but require confirmation in actual sports contexts.     

Sex differences and individual consistency in voice identification

Results were combined from 5 experiments by Cook in 1998 with 728 participants who listened to one male voice and one female voice each saying a sentence, then attempted to recognise the voices from line-ups of six voices presented a week later. While 352 male listeners did not differ significantly in recognising female and male voices (38% correct vs 41%), 376 female listeners were significantly more likely to recognise female than male voices (51% vs 43% correct). There was no evidence for individual differences in voice recognition in that listeners who recognised the male voice were no more likely to recognise the female voice than those who failed to recognise the male voice.     

Comparative analysis of different correction methods for measuring Rod-and-Frame Test performance

A comparative analysis was conducted of five different methods for scoring the Rod-and-Frame Test to examine the convergent validities of each of the five methods with performance on the Embedded Figures Test for a sample of 408 13- to 16-yr.-olds. The scoring methods included the absolute error, the algebraic error, the absolute value of the algebraic error, the frame effect, and an assessment of relative field dependence. Correlations obtained among the five methods and the Embedded Figures Test indicated different patterns for boys and girls. In general, the method which employed the absolute value of the algebraic error yielded the strongest convergent validity coefficients with scores on the Embedded Figures Test and Group Embedded Figures Test for boys (.62 and -.54, respectively), although, for girls, the absolute algebraic error and absolute error both yielded coefficients of .50 with Embedded Figures Test scores and -.46 with Group Embedded Figures Test scores.     

Flight and abduction in witchcraft and UFO lore

The lore surrounding the mythical Witches' Sabbat and contemporary reports of UFO abductions share three main characteristics: the use of masks, the appearance of "Men in Black," and references to flight and abduction. We review these three commonalities with particular focus on the aspect of flight and abduction. We argue that narratives of the Witches' Sabbat and UFO abductions share the same basic structure, common symbolism, and serve the same psychological needs of providing a coherent explanation for anomalous (ambiguous) experiences while simultaneously giving the experient a sense of freedom, release, and escape from the self. This pattern of similarities suggests the possibility that UFO abductions are a modern version of tales of flight to the Sabbat.     

Job insecurity in a sample of Canadian civil servants as a function of personality and perceived job characteristics

Economic downturns and organisational changes have stimulated studies on the importance of job security for public employees; however, there has been some disagreement as to whether job insecurity should be defined using a single- or a two-factor model, on how to measure it and which antecedents and consequences are linked to it. Questionnaires measuring job insecurity as well as personality traits and job characteristics as possible antecedent variables, and job performance and job satisfaction as possible consequences were completed by a sample of 71 federal government employees during recent important government downsizing. A multiple regression analysis indicated that job insecurity, defined as a combination of organisational or personal vulnerability, was significantly related to only two antecedent variables, i.e., Neuroticism and job characteristics. Further regression analyses indicated that job insecurity was a statistically significant moderator but only between one consequence, i.e., intention to quit, and the job characteristics variable. These results along with methodological issues and further research, are discussed.     

On the locus of the semantic satiation effect: Evidence from event-related brain potentials

The present study sought to determine whether semantic satiation is merely a by-product of adaptation or satiation of upstream, nonsemantic perceptual processes or whether the effect can have a locus in semantic memory. This was done by measuring event-related brain potentials (ERPs) in a semantic word-detection task involving multiple presentations of primes and critical related and unrelated words in three experiments involving visual (Experiment 1) and auditory (Experiments 2A and 2B) stimuli. Primes varied in their type case (Experiment 1) or pitch (Experiment 2B) in order to discourage sensory adaptation. Prime satiation and relatedness of the primes to the critical word had interacting effects on ERP amplitude to critical words, particularly within the time-window of the N400 component. Because numerous studies have indicated a role for the N400 in semantic processing, modulation of the N400 relatedness effect by prime satiation (with little or no contribution from perceptual adaptation) suggests that semantic memory can be directly satiated, rather than the cost to semantic processing necessarily resulting from impoverishment of perceptual inputs.
