Gaze direction affects visuo-spatial short-term memory

Hemispheric asymmetries were investigated by changing the horizontal position of stimuli that had to be remembered in a visuo-spatial short-term memory task. Observers looked at matrices containing a variable number of filled squares on the left or right side of the screen center. At stimulus offset, participants reproduced the positions of the filled squares in an empty response matrix. Stimulus and response matrices were presented in the same quadrant. We observed that memory performance was better when the matrices were shown on the left side of the screen. We distinguished between recall strategies that relied on visual or non-visual (verbal) cues and found that the effect of gaze position occurred more reliably in participants using visual recall strategies. Overall, the results show that there is a solid enhancement of visuo-spatial short-term memory when observers look to the left. In contrast, vertical position had no influence on performance. We suggest that unilateral gaze to the left activates centers in the right hemisphere contributing to visuo-spatial memory.     

The Ahmadiyya and the Study of Comparative Religion in Indonesia: Controversies and Influences

As an organization of foreign origin, the existence and contribution of the Ahmadiyya in Indonesia has been a subject of debate. Some scholars ignore it completely as unimportant, while others consider that it has had significant influence. The contribution of the Ahmadiyya to Indonesian Islam most asserted by the movement itself is its efforts to check and respond to Christian missionary activity. In what way has the movement actually made a contribution to that effort? How widespread is the influence of the Ahmadiyya in the discourse on Christianity, in particular, and the study of comparative religion, in general, in Indonesia? Why has the Ahmadiyya paid more attention to the issue of Christianity than other Muslim groups? This article aims to answer these questions by analysing literature on Christianity written and distributed by the Ahmadiyya in Indonesia and the effect this has had on relations between Islam and Christianity in two fields – religious mission and academia. The article presents three propositions. First, Ahmadiyya literature, with its apologetic, polemical and controversial character, had a significant influence on the academic study of comparative religion during two periods of instability: the late colonial era and the first two decades after the declaration of independence in 1945. Second, Ahmadiyya literature on Christianity has been most influential through the way it sets out to create a sense of the superiority of Islam and its compatibility with modernity. Third, for the Ahmadiyya, the issue of Christianity, particularly the death of Jesus, has been used as evidence that Mirza Ghulam Ahmad is the second Messiah.     

Teaching Comparative Theology from an Institution's Mission

Although comparative theology is a continuously growing method in the study of religion, it is still relatively new and not widely accepted in either confessional or secular institutions. Scholars may face difficulty when seeking their institutions' acceptance for a comparative theology course. One way of generating interest and approval for such a course is by designing it from the center of the institution's mission. Professors can look to the institution's mission as a resource for teaching comparatively. We offer four examples from Catholic institutions of how this might be done. Reid Locklin offers further insights in his response to our explorations.     

The effect of spatial organization of targets and distractors on the capacity to selectively memorize objects in visual short-term memory

We conducted a series of experiments to explore how the spatial configuration of objects influences the selection and the processing of these objects in a visual short-term memory task. We designed a new experiment in which participants had to memorize 4 targets presented among 4 distractors. Targets were cued during the presentation of distractor objects. Their locations varied according to 4 spatial configurations. From the first to the last configuration, the distance between targets’ locations was progressively increased. The results revealed a high capacity to select and memorize targets embedded among distractors even when targets were extremely distant from each other. This capacity is discussed in relation to the unitary conception of attention, models of split attention, and the competitive interaction model. Finally, we propose that the spatial dispersion of objects has different effects on attentional allocation and processing stages. Thus, when targets are extremely distant from each other, attentional allocation becomes more difficult while processing becomes easier. This finding implicates that these 2 aspects of attention need to be more clearly distinguished in future research.     

Effects of facial expressions on visual short-term memory in relation to alexithymia traits

We examined dysfunctional memory processing of facial expressions in relation to alexithymia. Individuals with high and low alexithymia, as measured by the Toronto Alexithymia Scale (TAS-20), participated in a visual search task (Experiment 1A) and a change-detection task (Experiments 1B and 2), to assess differences in their visual short-term memory (VSTM). In the visual search task, the participants were asked to judge whether all facial expressions (angry and happy faces) in the search display were the same or different. In the change-detection task, they had to decide whether all facial expressions changed between successive two displays. We found individual differences only in the change-detection task. Individuals with high alexithymia showed lower sensitivity for the happy faces compared to the angry faces, while individuals with low alexithymia showed sufficient recognition for both facial expressions. Experiment 2 examined whether individual differences were observed during early storage or later retrieval stage of the VSTM process using a single-probe paradigm. We found no effect of single-probe, indicating that individual differences occurred at the storage stage. The present results provide new evidence that individuals with high alexithymia show specific impairment in VSTM processes (especially the storage stage) related to happy but not to angry faces.     

The Holy Spirit in Mission

God initiated mission and intends to achieve it by work of the Holy Spirit. Thus, mission—which God commands his church to accomplish—belongs to God, not to human agency. Prior to ascending to heaven, Jesus promised the Holy Spirit to his disciples, and asked them to wait in Jerusalem. This Holy Spirit is given to enable them to be witnesses of Jesus from Jerusalem to the end of the world. This implies that the church has to partner with the Holy Spirit to fulfil this mission. Missionaries need to consciously work together with Spirit and be directed and guided by the Spirit.     

Re-examination of “release-from-PI” phenomena: recall accuracy does not recover after a semantic switch

Recall accuracy decreases over successive memory trials using similar memoranda. This effect reflects proactive interference (PI) – the tendency for previously studied information to reduce recall of new information. However, recall improves if memoranda for a subsequent trial are semantically dissimilar from the previous trials. This improvement is thought to reflect a release from PI. We tested whether PI is reduced or released from the semantic category for which it had been induced by employing paradigms which featured inducement, semantic switch, and then return-to-original category epochs. Two experiments confirmed that PI was not released after various semantic switch trials (effects from d?=??0.93 to ?1.6). Combined analyses from both studies demonstrated that the number of intervening new category trials did not reduce or release PI. In fact, in all conditions recall accuracy decreased, demonstrating that PI is maintained and can increase after the new category trials. The release-from-PI account cannot accommodate these broader dynamics of PI. This account is also incongruent with evidence and theory from cognitive psychology, linguistics, and neuroscience. We propose a reintroduction-of-PI account which explains these broader PI dynamics and is consistent with the wider psychological and neurosciences.     

Vocational integrity

Luther's doctrine of vocation is about faithfully living the baptismal life. This article argues that for the Christian a theology of work—vocation—is not to be constricted to the spiritual sphere only. The Christian is called from the temporal sphere, but not out of it. As such, the Christian embraces the spiritual and temporal spheres in response to God's grace and for the good of the neighbor.     

A provocation to mission: Constance Padwick's study of Muslim devotion

This article offers an examination of the work of Constance Padwick (1886–1968), who served as a ‘literature missionary’ with the Church Missionary Society and the International Missionary Council in Egypt and Palestine in the first half of the twentieth century. Through a study of Padwick's life-long engagement with popular Muslim devotional prayers, the article demonstrates how she was inspired to use language, devotion and liturgy to call for a richer, bolder and deeper Christian presence in the Muslim world. Formed by the prevailing Evangelical tradition of the epoch, Padwick was drawn to Islam's mystical tradition. Her commitment to teasing out underlying similarities between the two traditions influenced the theology of mission that she developed, as her study of Muslim devotions led her to encourage a greater emphasis on the contribution that Arabic Christian devotional literature could make to Protestant missions in the Muslim world. In addition to shaping a specific missiological approach, the experience of Islamic popular piety led her to exhort her colleagues to cooperate more closely with the Eastern churches in order to build up and strengthen the ancient Christian presence in the Arab world.     

Rediscovering Meaning

The present crisis of the Western countries involves not just the world of politics, finance, and the economy, but also the ecosystem balance, the world of the values on which the model of social organization and economic development is based. The crisis is therefore systemic, epoch-making, and overcoming it will require radical changes, above all in the way we think, in our scale of values, and therefore our culture. On the other hand, for decades the world—in particular the West—has been experiencing a cultural sea-change that is challenging many of the pillars of society that have stood for centuries. The young people of today and their use of technological social networks to develop non-profit initiatives for social change may create a more positive future while maintaining our human values.
