A comparison of cognitive processes and components of neurological maturation in 3-and-11 year-old children

The relationship between the child's cogni tive development and neurological maturation has been of theoretical interest for many year s. Due to diff iculties such as the lack of sophisticated techniques for measur ing neurolog ical changes and a paucity of normative data, few studies exist that have attempted to correlate the two factors. Recent theory on intellectual development has proposed that neurological maturation may be a factor in the increase of short-term memory storage space. Improved technology has allowed reliable recordings of neurolog ical maturation.. In an attempt to correlate cogni tive development and neurological maturation, this study tested 3-and II-year old children. Fine motor and gross motor short-term memory tests were used to index cogni tive development. Somatosensory evoked potentials elici ted by median nerve stimulation were used to measure the time required for the sensation to pass along the nerve to specific points on the somatosensory pathway. Times were recorded for N14, N20, and P22 interpeak latencies. Maturation of the central nervous system (brain and spinal cord) and the peripheral nervous system (outside the brain and spinal cord) was indi~ated by the recorded times. Signif icant developmental di fferences occurred between 3-and ll-year-olds in memory levels, per ipheral conduction velocity and central conduction times. Linear regression analyses showed that as age increased, memory levels increased and central conduction times decreased. Between the ll-year-old groups, there were no significant differences in central or peripheral nervous system maturation between subjects who achieved a 12 plus score on the digit span test of the WISC-R and those who scored 7 or lower on the same test. Levels achieved on the experimental gross and fine motor short-term memory tests differed significantly within the ll-year-old group.

The psychology of exclusivity

L’amitié et l’amour romantique sont, de par leur nature, des relations exclusives. Cet article suggère que l’on peut mieux comprendre la nature de l’exclusivité dont il est question en comprenant l’erreur au coeur de la vision du raisonnement pratique que je nomme « le point de vue englobant » . Selon le PVE, pour que le raisonnement pratique soit rationnel, il doit s’agir d’un processus ayant pour but de choisir la meilleure alternative possible à partir d’une perspective qui est aussi détachée et objective que possible. Quoique cette vision cherche à être neutre à l’égard des porteurs de valeurs, elle incorpore en fait un biais contre les porteurs de valeurs qui ne peuvent être appréciés qu’à partir d’une perspective qui n’est pas détachée - qui ne peuvent être appréciés, par exemple, que par les agents qui sont engagés à long terme envers les valeurs en question. Dans le contexte des relations personnelles, de tels engagements tendent à donner naissance à la sorte d’exclusivité qui caractérise l’amitié et l’amour romantique ; ils empêchent l’agent d’être impartial entre les besoins, les intérêts, etc. de la personne qui lui est chère, d’une part, et ceux des autres, d’autre part. Je suggère que dans de tels contextes les besoins et les revendications des autres personnes peuvent être réduites au silence, de la même manière que, comme le suggère John McDowell, les tentations de l’immoralité sont, pour l’agent vertueux, réduites au silence.

Verbal proficiency as fitness indicator: Experimental and comparative research on the evolutionary psychology of language and verbal displays

Summary: Recent research on the evolution of language and verbal displays (e.g., Miller, 1999, 2000a, 2000b, 2002) indicated that language is not only the result of natural selection but serves as a sexually-selected fitness indicator that is an adaptation showing an individual’s suitability as a reproductive mate. Thus, language could be placed within the framework of concepts such as the handicap principle (Zahavi, 1975). There are several reasons for this position: Many linguistic traits are highly heritable (Stromswold, 2001, 2005), while naturally-selected traits are only marginally heritable (Miller, 2000a); men are more prone to verbal displays than women, who in turn judge the displays (Dunbar, 1996; Locke & Bogin, 2006; Lange, in press; Miller, 2000a; Rosenberg & Tunney, 2008); verbal proficiency universally raises especially male status (Brown, 1991); many linguistic features are handicaps (Miller, 2000a) in the Zahavian sense; most literature is produced by men at reproduction-relevant age (Miller, 1999). However, neither an experimental study investigating the causal relation between verbal proficiency and attractiveness, nor a study showing a correlation between markers of literary and mating success existed. In the current studies, it was aimed to fill these gaps. In the first one, I conducted a laboratory experiment. Videos in which an actor and an actress performed verbal self-presentations were the stimuli for counter-sex participants. Content was always alike, but the videos differed on three levels of verbal proficiency. Predictions were, among others, that (1) verbal proficiency increases mate value, but that (2) this applies more to male than to female mate value due to assumed past sex-different selection pressures causing women to be very demanding in mate choice (Trivers, 1972). After running a two-factorial analysis of variance with the variables sex and verbal proficiency as factors, the first hypothesis was supported with high effect size. For the second hypothesis, there was only a trend going in the predicted direction. Furthermore, it became evident that verbal proficiency affects long-term more than short-term mate value. In the second study, verbal proficiency as a menstrual cycle-dependent mate choice criterion was investigated. Basically the same materials as in the former study were used with only marginal changes in the used questionnaire. The hypothesis was that fertile women rate high verbal proficiency in men higher than non-fertile women because of verbal proficiency being a potential indicator of “good genes”. However, no significant result could be obtained in support of the hypothesis in the current study. In the third study, the hypotheses were: (1) most literature is produced by men at reproduction-relevant age. (2) The more works of high literary quality a male writer produces, the more mates and children he has. (3) Lyricists have higher mating success than non-lyric writers because of poetic language being a larger handicap than other forms of language. (4) Writing literature increases a man’s status insofar that his offspring shows a significantly higher male-to-female sex ratio than in the general population, as the Trivers-Willard hypothesis (Trivers & Willard, 1973) applied to literature predicts. In order to test these hypotheses, two famous literary canons were chosen. Extensive biographical research was conducted on the writers’ mating successes. The first hypothesis was confirmed; the second one, controlling for life age, only for number of mates but not entirely regarding number of children. The latter finding was discussed with respect to, among others, the availability of effective contraception especially in the 20th century. The third hypothesis was not satisfactorily supported. The fourth hypothesis was partially supported. For the 20th century part of the German list, the secondary sex ratio differed with high statistical significance from the ratio assumed to be valid for a general population.

Students’ movement and participation in Latin-American psychology: historical and future perspectives

The historiographical paper presented is about the students’ activism and participation in the Latin American psychology. This aims are: 1) to provide a brief historic overview of the Latin American psychology; 2) to review on the students’ participation in the Latin American psychology; 3) to raise students’ future perspectives for the Latin American psychology. It is recognized that there is an extensive past of Latin American psychology and an emerging historiographical work that re fl ects that past.However, there are several historiographical gaps not covered yet by the investigations in the region. In this context, this paper wants to contribute to the study of the students’ activism and participation in the Latin American psychology construction. The historical perspective is supported by the renewed historiographical conception called instant history” which focuses on ancient and recent history at the same time. Indirect sources were used: articles, monographs and compiled editions.

Emotional characteristics of psychology students: a study based on the formative research perspective

In the formative research scheme, the author built a psychological scale, with the purpose of analyzing psychological characteristics of the School of Psychology students. The instrument showed a high reliability coefficient (α=0,86), the exploratory factorial analysis found five variables which allowed to predict some aspects of sex and career level through a logistic regression; the ALSCAL showed two emotional dimensions. The author recommends to improve the instrument and to continue its application in the School. It is also necessary to develop qualitative research to acquire new data about the topic of the research.

Impulsivity: A view from the behavioral neuroscience and developmental psychology

Impulsivity has been linked to three main factors: performing without direct involvement of the frontal lobe functions, an increase in the speed of response, and the acquisition of immediate gratification. This behavioral inhibition deficit involves a variety of behaviors including aspects of hyperexcitability, behavioral disinhibition and higher order decision making. Although by tradition, the definition of this executive function has been conceptualized from a psychopathological view, currently, the wide variety of neuropsychological, developmental and animal models assessment techniques encourage us to establish dialogues that integrate the knowledge of these theoretical perspectives for the interpretation and understanding of impulsivity.

Bibliography profiling of undergraduate theses in a professional psychology program

The bibliographic profile of 125 undergraduate (licentiate) theses was analyzed, describing absolute quantities of several bibliometric variables, as well as within-document indexes and average lags of the references. The results show a consistent pattern across the years in the 6 cohorts included in the sample (2001-2007), with variations, which fall within the robust confi dence intervals for the global central tendency. The median number of references per document was 52 (99% CI 47-55); the median  percentage of journal articles cited was 55%, with a median age for journal references of 9 years. Other highlights of the bibliographic profile were the use of foreign language references (median 61%), and low reliance on open web documents (median 2%). A cluster analysis of the bibliometric indexes resulted  in a typology of 2 main profiles, almost evenly distributed, one of them with the makeup of a natural science bibliographic profile and the second within the style of the humanities. In general, the number of references, proportion of papers, and age of the references are close to PhD dissertations and Master theses, setting a rather high standard for undergraduate theses.
