Personality factors in relation to violent crimes

The personalities of a group of 54 persons (51 men and 3 women), imprisoned for the perpetration of violent crimes, were evaluated. The results were then compared to a normative group. This study considers personality factors and dimensions on three levels: (a) Basic factors: the "Big Five", (b) Personality disorders and clinical syndromes, (c) Personality dimensions related to personal wellbeing and social adaptation said to define a psychologically healthy individual. The results of the study show that it is not possible to define a basic personality profile for this group of violent delinquents based on the "Big Five" factors. It is, however, possible to find two habitual patterns of behaviour if the Millon Model (1990) is applied. These two behaviour patterns and attitudes towards life situations will be named "Dependent with compulsive traits" and "Psychopath tendencies". Both relate to indicators of mental health.     

Influence of articulation rate on two memory tasks in young and older adults

This study investigated the relation between phonological loop functioning and age. Phonological loop is a time-based subsystem of the Working Memory Model of Baddeley and Wilson, which uses rehearsal of information as an active process to avoid phonological decay. Performance differences were examined between young and older adults in two speech-based memory tasks, such as the immediate serial recall of words and the Digit Ordering Task. Analysis showed that performance on both tasks was lower for the older group. Articulation rate was also measured to test the hypothesis that the impairment of some cognitive functions in adults can be associated to their slowness or the greater time needed by older adults for the rehearsal process. A significant negative correlation was found for articulation rate with age. When the effect of articulation rate on Serial Recall and Digit Ordering Tasks was partialled out, the difference between the two groups was eliminated.     

The Development of Hyperactive–Impulsive Behaviors During the Preschool Years: The Predictive Validity of Parental Assessments

The objectives of this study were to establish the different developmental trajectories of hyperactive-impulsive behaviors on the basis of both mother and father ratings at 19, 32, 50, and 63 months, and to examine the predictive validity of these trajectories with respect to later hyperactive-impulsive behaviors, as rated by teachers in the first 2 years of school. Hyperactive-impulsive behaviors were assessed in a population-based sample of 1,112 twins (565 boys and 547 girls) at 19, 32, 50, and 63 months of age. The results revealed a differentiated and consistent view of developmental trajectories of hyperactive-impulsive behaviors derived from these repeated assessments, with 7.1% of children seen by mothers (7% for fathers) as displaying high and stable hyperactive-impulsive behaviors. According to mother ratings, children on a high-chronic trajectory were more likely than other children to display hyperactive-impulsive behaviors at 72 and 84 months according to their teachers. Repeated measures over time and father-based trajectories significantly added to the prediction teacher later ratings of hyperactive-impulsive behaviors. These results support the predictive validity of parental assessment of hyperactive-impulsive behaviors during the preschool years and their use to identify children at risk for further evaluation and possible intervention.     

What is the impact of the explicit knowledge of sequence regularities on both deterministic and probabilistic serial reaction time task performance?

The aim of this study was to explore the role of prior explicit sequence knowledge by comparing its influence on serial reaction time (SRT) performance with either a deterministic or a probabilistic sequence. The results confirm that, with a deterministic sequence, preliminary explicit learning improves SRT performance. On the other hand, with a probabilistic sequence, the results show no advantage for SRT performance in explicit-learning conditions. In addition, by using the process dissociation procedure (Jacoby, 1991), we show that performance on a subsequent generation task was more sustained by controlled processes for participants in the explicit-learning conditions than for those in the incidental condition. On the whole, these results, showing that the influence of explicit knowledge can be suppressed in certain specific conditions, are consistent with the intervention of both implicit and explicit mechanisms in SRT tasks, and the results also show that their relative influence can be modulated by the particular demands of the task.     

科学对“后世”声称的检验（一）

后世存在有证据吗？我们能否与亡者进行沟通？他们的存在是否具有一定的形式呢？是“脱离肉体的灵魂”或是“无实体的精神”？这是个古老的问题,它事关信仰永生和强烈的对不朽的渴望。科学能否调查和揭示那些基于有神论信仰者利益的声明吗？回答是肯定的。科学在尽其所能来回应这些声称时要面对不仅仅是宗教学家们所倡导的灵魂不朽和天堂许诺等内容对人们的深刻影响,还要迎接来自媒体和公众的艰巨的挑战,媒体不断追求轰动效应,庞大的公众群体迷恋于此类现象。     

Self‐Construals,Motivation, and Feedback‐Seeking Behaviors

The current study explores the relations between individualism, motivation, and feedback‐seeking behaviors. Specifically, we examined how three motivational factors (i.e., status‐striving, achievement‐striving, and affiliation‐striving) mediated or moderated the relations between individualism and feedback‐seeking behaviors. Data were collected from 154 Singaporean undergraduate students across two time periods. Results indicated that only status motivation mediates the individualism–feedback‐seeking relation. Affiliation was found to moderate that same relation but only for a specific subset of feedback‐seeking behaviors. The implications of these findings for performance management and development are discussed.     

Priming the mental time-line: effects of modality and processing mode

The notion of a mental time-line (i.e., past corresponds to left and future corresponds to right) supports the conceptual metaphor view assuming that abstract concepts like “time” are grounded in cognitively more accessible concepts like “space.” In five experiments, we further investigated the relationship between temporal and spatial representations and examined whether or not the spatial correspondents of time are unintentionally activated. We employed a priming paradigm, in which visual or auditory prime words (i.e., temporal adverbs such as yesterday, tomorrow) preceded a colored square. In all experiments, participants discriminated the color of this square by responding with the left or the right hand. Although the temporal reference of the priming adverb was task irrelevant in Experiment 1, visually presented primes facilitated responses to the square in correspondence with the direction of the mental time-line. This priming effect was absent in Experiments 2, 3, and 5, in which the primes were presented auditorily and the temporal reference of the words could be ignored. The effect, however, emerged when attention was oriented to the temporal content of the auditory prime words in Experiment 4. The results suggest that task demands differentially modulate the activation of the mental time-line within the visual and auditory modality and support a flexible association between conceptual codes.     

Letter transpositions within and across morphemic boundaries: Is there a cross-language difference?

Research on the impact of letter transpositions that arise across morpheme boundaries has yielded conflicting results. These results have led to the suggestion that a cross-linguistic difference may exist in the recognition of Spanish and English words. In two masked-priming experiments run on separate groups of Spanish and English speakers, we tested this hypothesis by comparing the impacts of primes with letter transpositions that arose within morphemes or across morpheme boundaries on the recognition of identical or near-identical Spanish–English cognate targets. The results showed transposed-letter benefits in both Spanish and English that were not modulated by the position of the transposed letter in the prime stimulus. Our findings therefore add to the growing body of literature suggesting that the transposed-letter benefit is not affected by the position of the transposed letters relative to the morpheme boundary, and they dispel previous suggestions that there might be a genuine difference in orthographic coding across the Spanish and English writing systems.     

Abduction in economics: a conceptual framework and its model

We discuss in this paper the scope of abduction in Economics. The literature on this type of inference shows that it can be interpreted in different ways, according to the role and nature of its outcome. We present a formal model that allows to capture these various meanings in different economic contexts.     

A longitudinal study of psychosocial distress in breast cancer: Prevalence and risk factors

This longitudinal study was conducted among 102 women with non-metastasic breast cancer to identify the time evolution and prevalence of distress at specific times through diagnosis and treatment of disease: preliminary diagnosis, surgery, definitive diagnosis and chemotherapy. Additionally, the study aimed to examine the role of demographic, medical and psychosocial factors on distress. The results indicated that prevalence of distress was higher at initial diagnosis (25%) than the following time points (approximately 17%). The differences inter-individuals in the levels of distress were observed over the four assessments. No relation between distress and demographic and medical factors was found. However, psychosocial aspects were significant risk factors. Patterns of emotional suppression and specific coping responses like helplessness/hopelessness, anxious preoccupation, cognitive avoidance and fatalism were positively related to distress, whereas fighting spirit and perceived social support showed a protective role. Moreover, helplessness/hopelessness and anxious preoccupation jointly predicted 75% of cases and 98% non-cases of distress. Finally, a mediational model between emotional suppression and distress through helplessness/hopelessness was tested. Results support the necessity of routine distress screening all through the illness. Implications of data for psychosocial interventions with breast cancer patients are highlighted.
