Priming the mental time line

Growing experimental evidence suggests that temporal events are represented on a mental time line, spatially oriented from left to right. Support for the spatial representation of time comes mostly from studies that have used spatially organized responses. Moreover, many of these studies did not avoid possible confounds attributable to target stimuli that simultaneously convey both spatial and temporal dimensions. Here we show that task-irrelevant, lateralized visuospatial primes affect auditory duration judgments. Responses to short durations were faster when the auditory target was paired with left- than with right-sided primes, whereas responses to long durations were faster when paired with right- than with left-sided primes. Thus, when the representations of physical space and time are concurrently activated, physical space may influence time even when a lateralized, spatially encoded response is not required by the task. The time-space interaction reported here cannot be ascribed to any Spatial-Temporal Association of Response Codes effect. It supports the hypothesis that the representation of time is spatially organized, with short durations represented on the left space and longer ones on the right.     

Cerebellum and processing of negative facial emotions: cerebellar transcranial DC stimulation specifically enhances the emotional recognition of facial anger and sadness

Some evidence suggests that the cerebellum participates in the complex network processing emotional facial expression. To evaluate the role of the cerebellum in recognising facial expressions we delivered transcranial direct current stimulation (tDCS) over the cerebellum and prefrontal cortex. A facial emotion recognition task was administered to 21 healthy subjects before and after cerebellar tDCS; we also tested subjects with a visual attention task and a visual analogue scale (VAS) for mood. Anodal and cathodal cerebellar tDCS both significantly enhanced sensory processing in response to negative facial expressions (anodal tDCS, p=.0021; cathodal tDCS, p=.018), but left positive emotion and neutral facial expressions unchanged (p>.05). tDCS over the right prefrontal cortex left facial expressions of both negative and positive emotion unchanged. These findings suggest that the cerebellum is specifically involved in processing facial expressions of negative emotion.     

An inhibition effect in the temporal constrains of attentional selection: the Backward Blink

The study aims at investigating the dynamics of visual information processing during sequential control of attentional selection. By combining two different traditional paradigms we show for the first time that during rapid selection of visual targets, encoding of a new target stimulus is facilitated by suppression of the preceding relevant stimulus category (Backward Blink; BB). Such inhibition would operate to reduce interference from previously stored information, in order to facilitate the instantiation of a new attentional episode. Results suggest that the same underlying inhibitory mechanism might contribute to two different attentional effects, specifically, the switch cost and the Attentional Blink, suggesting a general inhibitory mechanism of attentional control, with broad implications for understanding how the brain perceives any task-relevant stimulus.     

BARBOUR'S TYPOLOGIES AND THE CONTEMPORARY DEBATE ON ISLAM AND SCIENCE

Abstract Despite various criticisms, Ian Barbour's fourfold classification of the possible relationships between religion and science remains influential. I compare Barbour's taxonomy with the theories of four authors who, in the last four decades, have addressed the relationship between science and religion from a Muslim perspective. The aim of my analysis is twofold. First, I offer a comparative perspective to the debate on science and Islam. Second, following Barbour's suggestion, I test the general applicability of his categories by comparing them with a discourse on science and religion that is not focused on Christianity. In the first section, I reconstruct Barbour's typologies, recalling some major objections to them, and arguing why despite the latter, Barbour's model is employed for the present analysis. I also reconstruct Barbour's parallel model for the relationships between different religions. In the second section, I reconstruct the discourse on science and religion developed by the Palestinian‐American scholar Ismail Raji al‐Faruqi. The third section is devoted to the ideas of the Persian‐American scholar Seyyed Hossein Nasr. In the fourth section, I examine the views of the Iranian author Mehdi Golshani. The fifth section reconstructs the theories of the Algerian author Nidhal Guessoum. In the final section, I argue that a generalized use of the “integration” concept to refer to the entire debate on Islam and science is unhelpful. While these positions do not appear to instantiate Barbourian integration of science and religion, they do move toward what Barbour (skeptically) describes as integration between religions.     

Grandiose Fantasies and Low Self-Esteem: An Experimental Study

Grandiose states of mind could be an ineffective way to cope with low self-esteem. In fact, it is possible that grandiose fantasies would tend to induce doubts about personal worth and decrease self-esteem. This study explored whether grandiose fantasies help to cope with low self-esteem. The self-reported occurrence and unpleasantness of intrusive thoughts regarding the sense of exclusion, humiliation, and low self-esteem in non-clinical individuals were assessed during self-induced grandiose fantasies and self-induced relaxation. The occurrence and unpleasantness of low self-esteem intrusions were significantly higher during grandiose fantasies, suggesting that grandiose fantasy is ineffective at combating low self-esteem.     

Reliability of self-reported attachment style in patients with severe psychopathology

Little is known about whether severe psychopathology influences the assessment of self-reported attachment style. Fifty-eight randomly selected adult psychiatric inpatients completed the Experiences in Close Relationship questionnaire (ECR; Brennan, Clark, & Shaver, 1998) and were administered the 24-item Brief Psychiatric Rating Scale (BPRS; Ventura et al., 1993) and the Hamilton Depression Rating Scale (HDRS; Hamilton, 1960) at both admission and discharge. The Structured Clinical Interview for DSM-IV (SCID-I; First, Spitzer, Gibbon, & Williams, 1996) was used to establish Axis I diagnoses. The ECR scales showed good internal consistency and absolute stability both in patients with (n = 24) and without (n = 34) a psychotic disorder. Relative stability was only fair among patients with psychotic disorders but good among patients without psychotic disorders. Neither higher BPRS or HDRS scores, nor the presence of a psychotic disorder, significantly reduced the retest reliability of the ECR scales. These findings suggest that self-report measures might provide a reliable assessment of attachment style in patients with severe psychopathology, except for the most severely impaired patients.     

Language and syntactic impairment following stroke in late bilingual aphasics

Purpose

Bilingual aphasia generally affects both languages. However, the age of acquisition of the second language (L2) seems to play a role in the anatomo-functional correlation of the syntactical/grammatical processes, thus potentially influencing the L2 syntactic impairment following a stroke. The present study aims to analyze the influence of late age of acquisition of the L2 on syntactic impairment in bilingual aphasic patients.

Methods

Twelve late bilingual participants (speaking French as L2 and either English, German, Italian or Spanish as L1) with stroke-induced aphasia participated in the study. The MAST or BAT aphasia batteries were used to evaluate overall aphasia score. An auditory syntactic judgement task was developed and used to test participants syntactic performance.

Results

The overall aphasia scores did not differ between L1 and L2. In a multiple case analysis, only one patient had lower scores in L2. However, four patients presented significantly lower performances in syntactic processing in the late L2 than in their native language (L1). In these four patients the infarct was localized, either exclusively or at least partially, in the pre-rolandic region.

Conclusion

This pilot study suggests that, in late bilingual aphasics, syntactic judgment abilities may be more severely impaired in L2, and that this syntactic deficit is most likely to occur following anterior lesions.     

Comparison between Gudjonsson Suggestibility Scale 2 (GSS2) and Bonn Test of Statement Suggestibility (BTSS) in measuring children’s interrogative suggestibility

Susceptibility of children to leading questions and interrogative pressure is an important forensic issue. The most used techniques for assessing interrogative suggestibility are the Gudjonsson Suggestibility Scales (GSS) and the Bonn Test of Statement Suggestibility (BTSS). Apart from minor differences, the two tests, investigate the same dimensions: Yield, Shift, Immediate Recall, and Total Suggestibility. In this study, to investigate correlation measures for the corresponding variables in the two tests, we individually examined 84 children from the fourth and fifth grades (44 boys and 40 girls). All the participants completed the GSS2 the BTSS-1, the Vocabulary and the Similarity subtests of the WISC-R, and Raven’s Colored Progressive Matrices. No significant gender differences were observed for any of the variables studied. Comparison between the corresponding variables for the two tests showed a positive correlation. Yield and Total Suggestibility scores correlated negatively with the three cognitive variables. We conclude that although the two suggestibility scales measure analogous variables, the BTSS seems more suitable than the GSS2 for assessing a child’s suggestibility during police and forensic interviews.     

The Efficient Assessment of Self-Esteem: Proposing the Brief Rosenberg Self-Esteem Scale

Self-esteem is defined as sense of self-worth and self-respect, being crucial for understanding people’s well-being and success. It is one of the most studied constructs in the social sciences, with the Rosenberg Self-Esteem Scale (RSES) being the most used measure. Across four studies (N = 1450), we tested the psychometric parameters of an abbreviated version of the RSES. Through Item Response Theory, the five best items were selected to form the unidimensional Brief Rosenberg Self-Esteem Scale (B-RSES), a reliable and valid measure of self-esteem, which is invariant across age groups and gender. In addition, both RSES and B-RSES correlated very similarly with the Big Five Personality Factors. Also, the B-RSES was strongly correlated with three other short measures of self-esteem, besides being more strongly associated with a range of variables such as conscientiousness and self-competence in comparison to the other three short scales. Together, the B-RSES is especially useful in research that requires rapid evaluation and the use of multiple variables.

     

Effects of verbal ability and fluid intelligence on children's emotion understanding

This study investigated the role of verbal ability and fluid intelligence on children's emotion understanding, testing the hypothesis that fluid intelligence predicts the development of emotion comprehension over and above age and verbal ability. One hundred and two children (48 girls) aged 3.6–6 years completed the Test of Emotion Comprehension (TEC) that comprised external and mental components, the Coloured Progressive Matrices and the Test for Reception of Grammar. Regression analysis showed that fluid intelligence was not equally related to the external and mental components of the TEC (Pons & Harris, 2000). Specifically, the results indicated that the external component was related to age and verbal ability only, whereas recognition of mental emotional patterns required abstract reasoning skills more than age and verbal ability. It is concluded that the development of fluid intelligence has a significant role in the development of mental component of emotion comprehension.
