Side-specificity of olfactory learning in the honeybee: US input side

In honeybees, Apis mellifera L., the proboscis extension reflex (PER) can be conditioned by associating an odor stimulus (CS) with a sucrose reward (US). As the neural structures involved in the detection and integration of CS and US are bilaterally symmetrical in the bee brain, we ask what respective role each brain side plays in the conditioning process. More specifically, the US normally used in conditioning experiments is the compound stimulation of the antennae (which triggers the PER) and of the proboscis (where bees lick the sucrose solution). Anatomically, the brain receives unilateral US input through each antenna, but bilateral input from the proboscis. By controlling each US component, we show that an antenna–US produces unilateral sensitization, whereas a proboscis–US or a compound–US induces bilateral sensitization. Bees can learn a unilateral odor CS with all three USs, but when a proboscis–US is used, new learning is inhibited on the contralateral side, owing to a possible US-preexposure effect. Furthermore, we show that the antenna–US induces both unilateral and bilateral reinforcement processes, whereas the proboscis–US produces only bilateral effects. Based on these data, we propose a functional model of the role of each brain side in processing lateralized CSs and USs in olfactory learning in honeybees.     

The Assessment of Individual Personality by Projective Tests: Current Problems

The Millon Clinical Multiaxial Inventory (MCMI) has been recently developed as an alternative to the Minnesota Multiphasic Personality Inventory (MMPI) and shares some of its psychometric advantages and disadvantages with the MMPI-168, a short form of the MMPI. The current study compared the structure and utility of the MCMI and MMPI-168 for a general hospital inpatient psychiatric population. Overall, the two instruments were highly correlated and found to have conceptually similar factor structures. Empirical comparison of the factor structures indicated that construct validity is greatest for neurotic traits. Both instruments demonstrated a similar utility in predicting discharge diagnosis.     

The Utility of the MAPI in the Assessment of Depression

The relationships between the Millon Adolescent Personality inventory (MAPI; Millon, Green, & Meagher, 1982) and depression, as assessed by the Multiscore Depression Inventory (MDI; Berndt, 1968) were examined. Elevations on the MDI subscales were positively related to elevations on MAPI personality style Scale 2 (Inhibited) and Scale 8 (Sensitive) and on six of the eight MAPI expressed concerns scales. MAPI personality style Scale 4 (Sociable) and Scale 5 (Confident) were negatively correlated with the MDI. MAPI code types containing either Scale 2 or 8 were associated with a high MDI full-scale score. The subjects who received a MAPI computer-generated diagnosis of borderline personality disorder also had elevated MDI full-scale scores. The findings of this study appear consistent with the existing body of MAPI research, and the data suggest that the MAPI personality style scales may have both state and trait qualities.     

Deconstructing ‘Western esotericism’: on Wouter Hanegraaff's Esotericism and the Academy

This paper discusses a number of consequences that – although not always intended by the author – can be drawn from the radically historicist approach adopted by Wouter J. Hanegraaff in his monograph Esotericism and the Academy. These consequences are the atomization of ‘esotericism’ into a disparate range of ideas, practices, and currents with few if any shared elements; a better approximation to contemporary anthropological views of culture and cultural innovation; a focus on polemical strategies rather than substantive contents and a concomitant possibility of cross-cultural comparison; a reluctance to engage with theories of broader scope; and a vacillation between seeing ‘esotericism’ as merely a waste-basket category and attempting nonetheless to salvage a minimal substantive definition.     

The Hydraulic Principles Governing the Function of the Cochlea

General equation. Rejecting all fantastic “anatomical” data, that is, not making any anatomical assumptions but those of facts which are clearly visible under the microscope, but, on the other hand, taking conscientiously into account everything that can thus be seen, we derive a general equation describing the hydraulic functions of the mammalian cochlea.

Statement of the chief aim of the theory. Whenever anything occurs on the outside which deserves to be called a sound in the sense of the physicist, and which varies more or less periodically with the time, we want to know first, what length or lengths of the phragma will be involved, because this determines the number of sensitive cells stimulated and thereby the magnitude of the nervous flux (or “the sensation intensity,” loudness); and we want to know second, how frequently per time unit these various lengths of the phragma are shaken, because this determines the nature of the stimulation and accordingly the quality of the chemical process resulting in each of those sensitive cells (or “the sensation quality,” pitch). Thus, our most important aim must be the establishment of a relation between l and t.

Solution of the equation. The equation is solved in special cases for two-fold verificaton: (1) by auditory observation; (2) by experimentation on a large, transparent, hydraulic model.

Thirty years without adverse criticism. The hydraulic theory during its life of thirty years has received some praise by the few who were willing to read it, has been viciously misrepresented by some who would not or could not comprehend it, has been innumerable times dogmatically rejected by those who did not even know what it consists in. We invite serious criticism of its basic assumptions, its mathematical analysis and, last but not least, its agreement with the facts of hearing.

The concept of a “traveling” bulge is not a part of the hydraulic theory. The author requests textbook and magazine writers to cease misquoting him. He has never either enounced or supported any “traveling” bulge theory.     

Studies in the Principles of Judgments and Attitudes: I. Two Basic Principles of Judgment

The psychological test performance of 10 seven-year-old boys from an isolated, rural Guatemalan village was compared with ratings of their intelligence made by 42 adult village members. The adults' judgments were found to correlate strongly with the children's performance on the Embedded Figures, Verbal Analogies, and Memory-for-Designs Tests.     

The Conflicting Demands of Work,Family, and School Among Students at an Urban University

The effects of perceived effectiveness of university support services and general satisfaction with the educational experience on conflicting demands of work, family, and school were investigated in a study of 375 undergraduate and graduate students at an urban university. Results demonstrated a negative relationship between perceived effectiveness of support services and the degree of work-school role conflict experienced by participants. Furthermore, satisfaction with educational experience was negatively related to work-school conflict. No other significant effects were found.     

Mental health,religion & culture

It has been found that the Muslim population in the UK seek spiritual advice from traditional faith healers for psychiatric and related problems. The important role that religious beliefs may have on perceptions of mental illness and substance misuse warrants further investigation. The aims were to examine the views of Muslims faith healers on symptoms and changes in behaviour commonly described as “psychosis” and “substance misuse”. Eight semi-structured interviews were conducted with Muslim faith healers from various backgrounds. Data were analysed according to the conventions of qualitative research using grounded theory methods. Religious conceptualisations played a key role in the understanding of both the disorders and consequently the guidance given. There were similarities and differences in the narratives given for psychosis and substance misuse. Healers expressed doubt towards other faith healers and the methods utilised by scientific means. The findings suggest a need for close collaboration between faith healers and mental health workers in order to achieve a culturally sensitive health care system.     

Measuring Spiritual Fitness: Atheist Military Personnel,Veterans, and Civilians

This study investigated the impact of transcendent item phrasing (i.e., phrasing which assumes the respondent believes in certain sacred or supernatural concepts) on the validity of the U.S. Army’s Comprehensive Soldier Fitness (CSF) program’s spiritual fitness scale when administered to atheist military personnel, veterans, and civilians. Results indicated that the inclusion of transcendent phrasing led to reduced concurrent validity for the spiritual fitness scale when administered to atheist military personnel and veterans, reduced concurrent and predictive validity when administered to atheists’ but not Christians’ spiritual fitness. Notably, the removal of transcendent phrasing actually led to increased concurrent validity for Christian respondents. Taken together, these findings suggest the Revised scale, which is composed of items that do not rely on transcendent phrasing, produces better psychometric outcomes for both atheist and Christian respondents. Implications for the CSF program and the measurement of spiritual fitness are addressed.
