Importance of Religion after Adversity

After major adversity, some people rely on their religious faith and networks for comfort, support, and material goods and services. Consistent with this behavior are findings that adversity has a positive causal effect on the importance of religion in people's lives. Using a large high-frequency US dataset, we estimate the causal effects of natural disasters on stated religious importance and attendance at religious services. Effects are identified by comparing changes in outcomes over time within counties affected by a natural disaster with changes over time in other counties from the same state. We find that most estimates are near-zero in magnitude; for the full sample, for subgroups defined by religious affiliation, demographics, and income, and for different disaster types. However, significant negative effects are found immediately postdisaster, suggesting a short-term crowding-out effect in which recovery activities limit time for worship. This explanation is supported by a finding that people are less “well rested” in the first weeks postdisaster.     

Brain Potential Studies of Perseveration: I. Perseveration Time to Light

In an effort to investigate the effects of attachment to the dominant culture and of developmental level on the self-concept, 62 male Lebanese-Americans of first, second, or third generation of residence in America completed two forms (questionnaire and adjective checklist) of an instrument designed to measure self-image disparity. A series of questions was used to measure extent of attachment to the Lebanese subculture, and a social competence index was employed as the measure of developmental level. No effects associated with self-image disparity emerged for generation of residence or developmental level. However, subjects who were strongly attached to the Lebanese culture showed less disparity on the questionnaire than those who were detached from it. Some support was provided for the developmental position, since Low Competence Ss made larger numbers of extreme responses on the questionnaire than the High Competence S.     

On Reinstating “Part I” and “Part II” to Wittgenstein's Philosophical Investigations

The Editors’ Preface to the fourth edition of Wittgenstein's Philosophical Investigations is disparaging of the earlier editorial efforts of G. E. M. Anscombe and Rush Rhees and in particular of their inclusion and titling of the material in “Part II”. I argue, on both historical and philosophical grounds, that the Editors have failed to refute the editorial decisions of Rhees and Anscombe – a failure born both of a neglect of the historical circumstances and Wittgenstein's own expressed hopes and intentions for his writings, and of a myopic understanding of his philosophy. Wittgenstein's legacy has not been well served by their interventions, which should be undone in future editions.     

Septal area lesions impair spatial working memory in homing pigeons (Columba livia)

The septo-hippocampal system in birds resembles that of mammals, motivating research into the function of the avian hippocampus while surprisingly little attention has been given to the septum. To investigate a possible role of the avian septum in memory, the effects of septal area lesions on a spatial working memory (SpWM) task was tested in homing pigeons. After preoperative training on an analogue eight-arm (feeders) radial maze, now sham-operated control and septal lesioned pigeons were then trained again on the same task of locating the four feeders on the test phase of a trial that were not baited during the sample phase of a trial. During the test phase of a working memory trial, septal lesioned pigeons, compared to both their own preoperative performance and the performance of the controls, required significantly more choices to locate the four baited feeders not baited during the sample phase of a trial, and they made significantly fewer correct responses to the now baited feeders on their first four choices. The results demonstrate that, like its mammalian counterpart, the avian septum plays an important role in SpWM, suggesting that at least some functional properties of the septum are evolutionarily conserved in birds and mammals.     

It Must Be My Favourite Brand: Using Retroactive Brand Replacements in Doctored Photographs to Influence Brand Preferences

We examined whether memories for personally chosen brands could be altered by retroactive exposure to less‐liked competitor brands embedded in manipulated photographs. In addition, we investigated whether memory errors would lead to preference change for falsely remembered brands. Fifty participants were asked to compile their personal ‘brand lifestyle basket’, which was then captured in a photo showing the basket and participant. After 1 week, participants were exposed to the photograph in which some of the originally chosen brands were replaced by different brands of the same category. Results of a memory test revealed a robust misinformation effect. The analysis of premanipulation and postmanipulation preference ratings indicated a positive shift in attitude and behaviour towards falsely accepted misinformation brands. Our findings contribute to what we know about the behavioural consequences of false memories and extend the generalizability of false memory effects to what might be considered a futuristic advertising measure.

Time-space learning in homing pigeons (<Emphasis Type="Italic">Columba livia</Emphasis>): orientation to an artificial light source

Time-space learning reflects an ability to represent in memory event-stimulus properties together with the place and time of the event; a capacity well developed in birds. Homing pigeons were trained in an indoor octagonal arena to locate one food goal in the morning and a different food goal in the late afternoon. The goals differed with respect to their angular/directional relationship to an artificial light source located outside the arena. Further, the angular difference in reward position approximated the displacement of the sun's azimuth that would occur during the same time period. The experimental birds quickly learned the task, demonstrating the apparent ease with which birds can adopt an artificial light source to discriminate among alternative spatial responses at different times of the day. However, a novel midday probe session following successful learning revealed that the light source was interpreted as a stable landmark and not as a surrogate sun that would support compass orientation. Probe sessions following a phase shift of the light–dark cycle revealed that the mechanism employed to make the temporal discrimination was prevailingly based on an endogenous circadian rhythm and not an interval timing mechanism.     

On Reinstating “Part I” and “Part II” to Wittgenstein’s Philosophical Investigations – A Supplementary Note

I have argued previously in this journal for the reinstatement of the titles “Part I” and “Part II” to Wittgenstein’s Philosophical Investigations, these having been replaced by “Philosophical Investigations” and “Philosophy of Psychology – A Fragment” by the editors of the 4th edition. My case for reinstatement was based principally on the written testimonies of Wittgenstein’s literary executors and first editors of the Investigations. Since the publication of my paper, further evidence of Wittgenstein’s publication intentions, from the diaries of his friend M. O’C. Drury, has come to my attention, which I now present. The current editors are urged to respond.     

Mapping sensorimotor sequences to word sequences: A connectionist model of language acquisition and sentence generation

In this article we present a neural network model of sentence generation. The network has both technical and conceptual innovations. Its main technical novelty is in its semantic representations: the messages which form the input to the network are structured as sequences, so that message elements are delivered to the network one at a time. Rather than learning to linearise a static semantic representation as a sequence of words, our network rehearses a sequence of semantic signals, and learns to generate words from selected signals. Conceptually, the network's use of rehearsed sequences of semantic signals is motivated by work in embodied cognition, which posits that the structure of semantic representations has its origin in the serial structure of sensorimotor processing. The rich sequential structure of the network's semantic inputs also allows it to incorporate certain Chomskyan ideas about innate syntactic knowledge and parameter-setting, as well as a more empiricist account of the acquisition of idiomatic syntactic constructions.
