Prospective Memory Impairment in Mild Cognitive Impairment: An Analytical Review

Mild cognitive impairment (MCI) is a heterogeneous condition characterized by the presence in an otherwise healthy elderly individual of cognitive deficits involving specific domains in the absence of significant functional impairments. Reports indicate that prospective memory (PM), that is, the ability to remember to execute delayed intentions, is impaired in individuals with MCI. The present review discusses the current debate in the literature on PM functioning in MCI by focusing on the relationship between prospective retrieval and retrospective memory functioning. Analysis of the reported evidence revealed that both the prospective component and the retrospective component of PM can be impaired in MCI. Declarative memory dysfunction may account for the retrospective memory impairment, while either reduced executive abilities or a deficit of reflexive mechanisms could explain the prospective component impairment.     

First and second language vowel perception in early bilinguals

Previous research has shown that the perception of speech sounds is strongly influenced by the internal structure of maternal language categories. Specifically, it has been shown that stimuli judged as good exemplars of a phonemic category are more difficult to discriminate from similar sounds than bad exemplars from equally similar sounds. This effect seems to be restricted to phonemes present in the maternal language, and is acquired in the first months of life. The present study investigates the malleability of speech acquisition by analysing the discrimination capacities for L2 phonemes in highly proficient Spanish-Catalan bilinguals born in monolingual families. In Experiment I subjects were required to give goodness of fit judgments to establish the best exemplars corresponding to three different vowel categories (Catalan /e/ and /ε/ Spanish /e/). In Experiments 2 and 3, bilinguals were asked to perform a discrimination task with materials in their maternal language (Exp. 2) and in their second language (Exp. 3). Results reveal that bilinguals show a reduced discrimination capacity only for good exemplars of their maternal language, but not for good exemplars of their second language. The same pattern of results was obtained in Experiment 4, using a within-subjects design and a bias-free discrimination measure (d'). These findings support the hypothesis that phonemic categories are not only acquired early in life, but under some circumstances, the acquisition of new phonemic categories can be seriously compromised, in spite of early and extensive exposure to L2.     

Bilingualism aids conflict resolution: evidence from the ANT task

The need of bilinguals to continuously control two languages during speech production may exert general effects on their attentional networks. To explore this issue we compared the performance of bilinguals and monolinguals in the attentional network task (ANT) developed by Fan et al. [Fan, J., McCandliss, B.D. Sommer, T., Raz, A., Posner, M.I. (2002). Testing the efficiency and independence of attentional networks. Journal of Cognitive Neuroscience, 14, 340-347]. This task is supposed to tap into three different attentional networks: alerting, orienting and executive control. The results revealed that bilingual participants were not only faster in performing the task, but also more efficient in the alerting and executive control networks. In particular, bilinguals were aided more by the presentation of an alerting cue, and were also better at resolving conflicting information. Furthermore, bilinguals experienced a reduced switching cost between the different type of trials compared to monolinguals. These results show that bilingualism exerts an influence in the attainment of efficient attentional mechanisms by young adults that are supposed to be at the peak of their attentional capabilities.     

Adaptation to time-compressed speech: phonological determinants

Perceptual adaptation to time-compressed speech was analyzed in two experiments. Previous research has suggested that this adaptation phenomenon is language specific and takes place at the phonological level. Moreover, it has been proposed that adaptation should only be observed for languages that are rhythmically similar. This assumption was explored by studying adaptation to different time-compressed languages in Spanish speakers. In Experiment 1, the performances of Spanish-speaking subjects who adapted to Spanish, Italian, French, English, and Japanese were compared. In Experiment 2, subjects from the same population were tested with Greek sentences compressed to two different rates. The results showed adaptation for Spanish, Italian, and Greek and no adaptation for English and Japanese, with French being an intermediate case. To account for the data, we propose that variables other than just the rhythmic properties of the languages, such as the vowel system and/or the lexical stress pattern, must be considered. The Greek data also support the view that phonological, rather than lexical, information is a determining factor in adaptation to compressed speech.     

Self-forgiveness and forgiveness-seeking in response to rumination: Cardiac and emotional responses of transgressors

Self-forgiveness and forgiveness-seeking are important and understudied aspects of forgiveness. We examined the cardiac and emotional patterns of healthy young adults (40 women, 40 men) who recalled an unresolved offense they had caused another person. Participants engaged in four imagery conditions: ruminating about the offense, being humbly repentant and engaging in self-forgiveness, seeking forgiveness from the victim and receiving forgiveness, and seeking forgiveness from the victim and being begrudged. Being repentant and begrudged forgiveness by one’s victim was associated with the same level of guilt as when ruminating, but significantly more negative emotion, less control, and less empathy than when ruminating, self-forgiving, and receiving forgiveness from the victim. Compared to ruminating about one’s wrongdoing, self-forgiving alleviated guilt and negative emotion, increased perceived control, decreased heart rate, and increased parasympathetic activation. Imagery of receiving forgiveness from the victim resulted in these same patterns and was equivalent to self-forgiveness across variables.     

Autonomy and interdependence: beliefs of Brazilian mothers from state capitals and small towns

This study aimed to investigate characteristics of Brazilian mothers' beliefs system, in the dimensions of autonomy and interdependence. A group of 600 women, half from state capitals and half from small towns, participated in the study. They were individually interviewed with Scales of Allocentrism, Beliefs about Parental Practices and Socialization Goals. Paired and Independent samples t tests and Multivariate GLM were performed. The results indicate that although mothers from both contexts value autonomy, mothers inhabiting small towns considered the relational dimension as the most important; whereas mothers inhabiting capitals valued equally both dimensions, either in their beliefs about practices or in the socialization goals for their children. Mothers from small towns have a higher mean score for allocentrism than mothers living in capitals. Thus, place of residence proved to be a relevant variable in the modulation of maternal beliefs. Educational level was not a significant factor in the variables considered and with this group of mothers. The study results are discussed in terms of their contribution to the understanding of the complex relationship between dimensions of autonomy and interdependence in mothers' beliefs system.     

On the Ethics of Democratic Access to Web Information

Floridi’s work, although diverse and multifaceted, portrays a solid coherence across his different lines of work. Among his wealth of interests and results, we highlight his recent work on information logics, on the ethics of information technology, and his rigorous (and vigorous) philosophical analysis of recent technological trends and developments in information technology. In the present article we illustrate, by means of some connecting arguments, the diversity and coherence of Floridi’s work. We also show how his work, although fundamentally philosophical in nature, can be used to build solid foundations for scientific and entrepreneurial endeavours of higher quality. More specifically, we discuss how the combination of results from the three lines of work referred to above can be used as ground for the organisation of higher quality programmes to augment the capabilities and effectiveness of governmental systems through information and communications technology, a trend that has been explored in many nations and that has been coined Electronic Government. Electronic Government programmes that improve the capabilities of citizens to interact with each other and with governments, as well as the capabilities of governments to listen to the needs and aspirations of citizens, have the potential to contribute to the construction of more democratic states. Electronic Government systems that rely on ready made models to prescribe to citizens how best they should interact with each other and with the public administration are, however, by construction non-democratic. Hence, it can be a moral and ethical matter for governments to choose which line of technological development they take.     

Nature over nurture: temperament, personality, and life span development

Temperaments are often regarded as biologically based psychological tendencies with intrinsic paths of development. It is argued that this definition applies to the personality traits of the five-factor model. Evidence for the endogenous nature of traits is summarized from studies of behavior genetics, parent-child relations, personality structure, animal personality, and the longitudinal stability of individual differences. New evidence for intrinsic maturation is offered from analyses of NEO Five-Factor Inventory scores for men and women age 14 and over in German, British, Spanish, Czech, and Turkish samples (N = 5,085). These data support strong conceptual links to child temperament despite modest empirical associations. The intrinsic maturation of personality is complemented by the culturally conditioned development of characteristic adaptations that express personality; interventions in human development are best addressed to these.     

Different selection principles of freestanding and bound morphemes in language production

Freestanding and bound morphemes differ in many (psycho)linguistic aspects. Some theorists have claimed that the representation and retrieval of freestanding and bound morphemes in the course of language production are governed by similar processing mechanisms. Alternatively, it has been proposed that both types of morphemes may be selected for production in different ways. In this article, the authors first review the available experimental evidence related to this topic and then present new experimental data pointing to the notion that freestanding and bound morphemes are retrieved following distinct processing principles: freestanding morphemes are subject to competition, bound morphemes not.
