Retrieval failure, rehearsal deficiency, and short-term memory loss in the aphasic adult

Studies show that aphasic patients typically are grossly impaired in short-term memory performance. Since aphasics generally experience difficulty in word retrieval, it is conceivable that short-term memory loss is partially the result of verbal rehearsal deficiency which, in turn, is caused by the word retrieval problem. This paper reports an experiment in which five aphasic adults were nonverbally to recall individualized lists of pictures they could easily name and lists of pictures they could not name. Final items in the two lists were recalled with equal accuracy; this was expected in that the recency effect usually reflects sensory rather than verbal storage. Initial items were recalled with greater accuracy than middle-list items in the nameable sets but not in the unnameable sets. This primacy effect suggests the aphasics rehearsed the nameable pictures, but both lists were recalled so poorly that rehearsal deficit was considered responsible for no more than a fraction of the aphasics' reduction in short-term memory.     

Stimulus- or response-induced excitation. A comparison of the behavior of introverts and extraverts

The tendency to inspect visual material (slides) rather than to respond by pressing a key in an attempt to move on to the next slide, was compared among introverts and extraverts. As predicted from Brebner and Cooper (1974): (1) extraverts inspected the stimuli for a shorter time before making their first response, (2) extraverts made more responses at a faster rate than introverts did, and (3) extraverts produced a significantly higher proportion of runs of accelerating responses.     

Lateral-frontal slow potential shifts preceding language acts in deaf and hearing adults

Slow potential EEG shifts (SPSs) recorded over Broca's area and the paired contralateral site preceding cued language acts have been reported to identify the language-dominant hemisphere. A contingent negative variation paradigm SPS method was applied to the comparative study of 10 hearing adults and of 10 adult prelingually deaf persons whose first learned language was American Sign Language. Volunteers performed both language and non-language acts in both oral and manual expressive modes. The hearing group showed no lateralized SPS, failing to replicate previous reports. The deaf group showed a nonsignificant trend opposite in laterality to that of hearing groups in previous reports.     

The effects of didactic classroom instruction versus field exposure on career maturity

This study tested two types of career training (field exposure and didactic classroom) to determine which is more effective in bringing about the development of career maturity. Forty-six first-year Upward Bound students were assigned to either a field exposure or a didactic group by the use of a stratified random assignment technique. A pretest/post-test design was utilized with the Career Maturity Inventory as the data-collecting instrument. The data were analyzed by analysis of covariance. The results of the study indicate that field exposure career training is an effective method to increase career maturity.     

Rhythm and dominance

Subjects were tested by a short experimental procedure involving tapping of a rhythm with one limb with a simultaneous regular beat with another limb. Informal observations had suggested a rhythm dominance effect—that is was dramatically easier with some limb combinations. Notably it was easy when the right hand tapped the rhythm and the left hand the beat but almost impossible the other way round. Equally, both hands dominated both feet. Our tests revealed enormous individual differences, subjects separating neatly into three groups. Some people could not do the task at all, some could do it with any limb combination, the latter group including all the serious musicians tested. For the remainder the rhythm dominance effect was clear. However, the laterality effect was the same (right hand advantage) for a majority (60%) of left handers. We conclude, then, that this effect is linked to language dominance and not handedness. In addition it seems there is a task scheduler which imposes its own view in combining this laterality effect with the dominance of hands over feet.     

A mathematical model for social influences on perceptual judgments

A mathematical model based upon signal detection theory is developed that characterizes social influences upon judgments of a stimulus. A social influence cue and the physical aspects of the stimulus were assumed to have independent effects upon performance. A visual movement discrimination task was employed in which subjects could make their judgment either before or after a cue that they had been led to believe was the response of another subject. The accuracy of this “response” was varied. The model provided a good account of the data. A model-based estimate of the magnitude of the influence effect indicated that this effect was greater when the “other” was highly accurate. The model provided an interpretation of social influences on perceptual judgments in which influence pressures have their effects only when subjects' sensory impressions are ambiguous.     

Jung Among the Physicists: A Review Essay of Dual-Aspect Monism and the Deep Structure of Meaning

This essay reviews the recent book by Harald Atmanspacher and Dean Rickles, Dual-Aspect Monism and the Deep Structure of Meaning. The essay aims to contextualize and clarify the book’s core argument about the theoretical and empirical fruitfulness of decompositional dual-aspect monism as an intervention into the mind-body problem that ascribes a pivotal role to meaning. The variants of dual-aspect monism discussed were developed primarily by physicists, but the essay also highlights the crucial contributions to the argument by the one non-physicist involved, Carl Gustav Jung, as well as noting the significance of dual-aspect monism and of the reviewed book for analytical psychology.     

The Life and Works of a Bottom-Up Thinker

A brief account is given of the author's life as a physicist and then a priest. The twin foundations of the author's theological endeavors have been a respect for traditional Christian thinking, though not exempting it from revision where this is needed, and a style of argument termed bottom-up thinking, which seeks to proceed from experience to understanding. The diversity of the world faith traditions is perceived as a major source of perplexity. A revised and modest natural theology and the issue of divine action have been at the top of a science and theology agenda. A defense is sketched in realist terms of the metaphysical strategy of using an ontological interpretation of the unpredictabilities of chaos theory to support a notion of top-down causality through active information. The success of Christian theology as a resource of total explanation depends on a credible account of eschatological hope. Reference is made to practical experience of ethics in the public square.     

Higher Pantheism

Romantic sensibility and political necessity led Humphry Davy, Britain's most prominent scientist in the first quarter of the nineteenth century, to pantheism: nature worship, involving for him a fervent belief in the immortality of the soul. Rapt with a vision of sublimity, from mountain tops or balloons, men of science in succeeding generations also found in pantheism a reason for their vocation and a way of making sense of their world. It should be seen as an alternative both to active participation in church life (like Faraday's) and to a gritty agnosticism (like Huxley's), indicating again how subtle and complex relationships were between science and religion in the nineteenth century.     

Mission,Reconciliation, and the Politics of Place

Through the retelling of some familiar biblical stories – Jonah, Acts 1, Acts 10 – and gospel narratives of inclusion, this paper looks at the transformation of politics and identities made possible by the sending of the Holy Spirit and the mission of reconciliation to which Christians are called. Through an examination of the themes of power, prejudice, partnership, and identity, the paper aims to offer a concrete approach to rethinking the spaces and places where a reconciling mission can be enacted. Central to an understanding of reconciliation are the disruption and transgressing of boundaries in which Jesus engaged. In addition to this, Jesus creates these unique spaces for reconciliation around his very person, and the Spirit leads the church into these same contexts. Finally, selections of John 17 are examined through a biographical lens in order to offer a new understanding of the politics of identity and the surprising contexts where God’s Spirit reconciles all things in Christ.
