Learning first-pass structural attachment preferences with dynamic grammars and recursive neural networks

One of the central problems in the study of human language processing is ambiguity resolution: how do people resolve the extremely pervasive ambiguity of the language they encounter? One possible answer to this question is suggested by experience-based models, which claim that people typically resolve ambiguities in a way which has been successful in the past. In order to determine the course of action that has been "successful in the past" when faced with some ambiguity, it is necessary to generalize over past experience. In this paper, we will present a computational experience-based model, which learns to generalize over linguistic experience from exposure to syntactic structures in a corpus. The model is a hybrid system, which uses symbolic grammars to build and represent syntactic structures, and neural networks to rank these structures on the basis of its experience. We use a dynamic grammar, which provides a very tight correspondence between grammatical derivations and incremental processing, and recursive neural networks, which are able to deal with the complex hierarchical structures produced by the grammar. We demonstrate that the model reproduces a number of the structural preferences found in the experimental psycholinguistics literature, and also performs well on unrestricted text.     

Sex-role stereotyping and patterns of self-disclosure

Students enrolled in psychology courses completed a Bem Sex-Role Inventory and a self-disclosure scale. A three way ANOVA (sex by sex role by target of disclosure) was used to determine if androgynous subjects differed from stereotyped by not conforming to standard sex differences in: (a) pattern of targets disclosed to; (b) amount of intimate disclosure. Results indicated: (a) androgynous females reported a peers first profile, typical of males; (b) androgynous males reported more disclosure than stereotyped males, especially on intimate topics; (c) androgynous females reported more nonintimate discussions with their fathers; and (d) androgynous males reported the highest level of intimate disclosures to father. Sex role is a better predictor of reported self-disclosure than is sex.The order of the authors' names was randomly determined: Both contributed equally.

Contexts and experimentalism in the psychology of Gabriele Buccola (1875-1885)

Gabriele Buccola, since his untimely death, often has been mentioned as the first Italian psychologist who developed a strict program of laboratory research. Buccola, a Sicilian of Albanian ancestry, is a "case" in the history of Italian psychology. A self-taught positivist, he established a relation with the major representatives of the European positivism. Kraepelin mentions him as one of the precursors of his project of applying experimental psychology to psychopathology. Buccola actually carried out research on the psychological, chemical-biological, and psychopathological "modifiers" of reaction times, following an experimental program dealing mainly with the differential study both of basic and superior psychological processes, with mental hygiene ends. Historians of psychology agree in considering Buccola the first Italian laboratory psychologist to plan a program of research that was close to European psychological experimentalism.The present article, starting from an outline of Buccola's role in the rising Italian scientific psychology, recontextualizes his experimentalism in an international sphere. This operation, which is carried out through a careful survey of Buccola's entire production-both theoretical and more properly scientific-is based on the search of the Darwinian, Spencerian, and Haeckelian evolutionist themes emerging from Buccola's program of research-a program that was influenced by the variegated European experimental panorama and characterized by the vision of science as a knowledge capable of transforming the nature of man and of society.     

Culture in the context of intercultural negotiation.

This study explores culture's effect on behaviors and outcomes in intercultural negotiation and examines how those effects are moderated by role. Eighty U.S. and international students took part in a previously developed negotiation task (Pruitt, 1981) and completed Hui and Triandis's (1986) individualism‐collectivism (INDCOL) scale. Negotiation interactions were coded for information sharing, offers, and distributive tactics. Findings show that a negotiation dyad's collectivism is positively associated with higher joint profit. The effects of culture on both communication behaviors and joint outcomes, however, differ by role of the negotiator. In particular, seller collectivism has larger and more consistent effects on communication behavior and joint profit than buyer collectivism. Results support a ‘culture in context’ perspective of negotiation that takes into account negotiator qualities, contextual and structural features of the negotiation, and mediating processes in addition to cultural values.     

Stereotype threat: the moderating role of Locus of Control beliefs

The goal of the present study was to test the moderating role of Locus of Control beliefs on performance deficits typically associated with stereotype threat. The results from Experiment 1 were consistent with predictions. First, consistent with the Stereotype Threat model, participants showed a decrease in performance when the task was perceived as a potential test of the in‐group's negative stereotype (lacking logical mathematical intelligence in the case of women and lacking social intelligence in the case of men). Most important, participants' Locus of Control beliefs were found to moderate participants' vulnerability to stereotype threat: individuals with an Internal Locus of Control, although generally performing better, showed a sharper decrease in the stereotype threat condition compared to individuals with External Locus of Control beliefs. Experiment 2 replicated the results from Experiment 1. Findings are discussed in relation to the psychological characteristics of Internal Locus of Control that may render individuals more vulnerable to the negative effects of stereotype threat.

Depression and Anxiety in Roman Catholic Secular Clergy

A nationally selected random sample of Roman Catholic secular priests was investigated using the Center for Epidemiological Studies-Depression scale and the State-Trait Anxiety Inventory Form Y. Additionally, a Self-Report Inventory requested information regarding participants' demographics as well as four categories of predictor variables (i.e., Vocational Satisfaction, Social Support, Spiritual Activities, Physical Environment) potentially associated with depression and anxiety. The study yielded a return rate of 64%. Secular clergy reported significantly greater depression and anxiety (both state and trait) than are reported in the general population. Low Vocational Satisfaction was found to be predictive of depression as well as both state and trait anxiety. Additionally, low Social Support was found to be predictive of state and trait anxiety. When the significant predictor variables were conceptually collapsed, it appeared that both people and place were significantly related to Roman Catholic secular priests' experience of depression and anxiety.     

THE CONTROL OF BIAS IN RATINGS: A THEORY OF RATING

Based on several years of research and a careful analysis of the rating process Wherry developed a theory of rating. An accurate rating is seen as being a function of three major components: Performance of the ratee, observation of that performance by the rater, and the recall of those observations by the rater. Cast in a mold of classical psychometric theory each of these components is seen as consisting of a systematic portion and a random portion. The systematic portion of each component is further broken down. The performance of the ratee is a combination of true ability or aptitude for the job and the influence of the environment. What the rater observes is a function the performance of the ratee and bias of observation and what the rater recalls is a result of those observations combined with a bias of recall. The development of the theory of rating unfolds by defining the various factors that affect each of these components in a series of linear equations. Various theorems and corollaries are proposed which should lead to a maximization of the true ability component of the ratee and minimize environmental influence and the bias and error components. The theorems and corollaries suggest testable hypotheses for the researcher in performance evaluation.     

Fer cryin' out loud — There is a sex difference

Self-reported crying behavior of 307 female and 285 male university students was studied. Female subjects reported crying significantly more frequently and intensely than did male subjects. In all six interpersonal situations female subjects indicated greater likelihood of crying than did male subjects. Significantly more females than males indicated they would cry in 17 of 20 stimulus situations. Where there were significant sex differences in reporting of postcrying affect, a higher percentage of females than of males indicated that they experienced the feelings described. The sample, with few exceptions, viewed females as crying more frequently than males. Despite these sex differences, many evidences of similarity between the sexes in crying behavior were found.An earlier version of this article was presented at the Western Psychological Association Meetings in San Diego, April 1979.     

Multimodal communication and spatial binding in pied currawongs (<Emphasis Type="Italic">Strepera graculina</Emphasis>)

To make accurate assessments about their environment, animals must integrate a variety of sensory cues into a single unified percept. The effects of redundant multimodal signaling may be equivalent to the responses elicited by each individual cue, or enhanced when cues are combined. Binding of two seemingly coupled cues can persist despite small spatial and temporal discrepancies in signal presentation, a phenomenon termed the ventriloquist effect. Our study had two aims: first, to test the cognitive ability of a territorial, forest-dwelling bird to bind two spatially disparate cues; and second, to define the processing of the acoustic and visual cues as having either equivalent or enhanced effects when presented together. We broadcasted pied currawong (Strepera graculina) vocalizations alone or in the presence of a model currawong situated either adjacent to, or far away from a speaker, to free-living currawongs. The number of locomotive events and the average standard deviation in the distance from the speaker maintained by the focal currawong were greater in response to "far" than "close" treatments. Additionally, the average standard deviation of the distance to speaker for the uni-modal, speaker only treatment was similar to "far" responses. These findings support our hypothesis that currawongs cognitively bind two stimuli in close spatial proximity. In nature, this would result in an enhanced level of response toward territorial intruders. Our study was novel in its attempt to assess cognitive processes involved in the integration of spatially disparate bimodal signaling events in free-living birds.
