Levels of representation in the interpretation of anaphoric reference and instrument inference

The level of representation accessed when inferences are made during sentence comprehension was examined. The inferences investigated included antecedent assignment for both definite noun phrase anaphors and pronouns and also instrument inferences. In making these inferences, a listener must access the inferred element, whether an antecedent or an instrument, in either a linguistic form representation or a discourse model. The level of representation involved in these inferences was determined by exploiting differences in the lexical-decision and naming tasks, which were argued to exhibit differential sensitivity to representational levels. In three experiments, the priming of antecedent and instrument targets in the lexical decision task was compared with priming of the same targets in the naming task. Differences in the patterns of activation across the two tasks indicated that all three types of inferences required-accessing-elements in a discourse model. Three control experiments ruled out simple context or congruity checking as an explanation for our results. The following conclusions were also supported by these studies: (1) Antecedent assignment occurs immediately after processing an anaphor; (2) antecedent assignment involves inhibition for the inappropriate antecedent rather than facilitation for the appropriate antecedent; (3) although subjects do not make instrument inferences-when they hear isolated sentences containing verbs that strongly imply certain instruments, the inferences are made when sentences are preceded by a context that mentions the instrument.     

Fertility, menstrual characteristics, and contraceptive practices among white, black, and Southeast Asian refugee adolescents

This study compares fertility and menstrual characteristics and contraceptive practices of white, black, and Southeast Asian refugee adolescents participating in the Minneapolis Health Department's Maternal and Infant Care Program between 1980 and 1982. Mean ages were similar among all racial groups; however, half the Hmong adolescents had a live birth as compared to less than 25% of the other racial groups. More than 75% of the Hmong and other Southeast Asian adolescents were married as compared to 11% of the whites and 8% of the blacks. Menarche was significantly later (2 years) for Hmong and other Southeast Asians, and the interval between menarche and first pregnancy was significantly shorter for the Hmong. While more than half of the whites and blacks previously used contraception, 14% of the Hmong and 29% of the other Southeast Asians had used contraception. Oral contraceptives were the most frequently used method for whites, blacks, and Southeast Asians; the Hmong were equally likely to choose oral contraceptives or barrier methods. The Hmong were less likely to choose contraception postpartum than were the other groups.     

Keep it local (and final): Remnant preferences in “let alone” ellipsis

The let alone construction (John can't run a mile, let alone a marathon) differs from standard coordination structures (with and or but) by requiring ellipsis of the second conjunct—for example, a marathon is the remnant of an elided clause [ John run a marathon]. In support of an ellipsis account, a corpus study of British and American English finds that let alone exhibits a Locality bias, as the second conjunct preferentially contrasts with the nearest lexical item of the same syntactic type. Two self-paced reading studies show that the Locality bias is active during online processing, but must be reconciled with indicators of semantic contrast and discourse information. Further, a sentence-rating study shows that the Locality bias interacts with a Finality bias that favours placing the let alone phrase at the end of a clause, which sometimes necessitates a nonlocal contrast. Together, the results show how a general bias in ellipsis for local contrasts is affected by discourse demands, such as the need for scalar contrast imposed by let alone, thereby offering a window into how possibly divergent syntactic and discourse constraints impact sentence processing.     

Beware the eyes behind the mask: The capture and hold of selective attention by backward masked fearful eyes

Fearful facial expressions are important social indicators of environmental threat. Among the various features of a fearful face, the eyes appear to be particularly important for recognizing and responding to these social cues. One way in which fearful faces facilitate observers’ behavior is by automatically capturing attention. This is true for both consciously and nonconsciously processed fearful faces. Recent research suggests that consciously processed fearful eyes alone are sufficient to capture observers’ attention. However, it is unknown as to whether or not nonconsciously processed, backward masked, fearful eyes are sufficient to facilitate spatial attention. To test this possibility, two dot-probe experiments with masked fearful eye stimuli were performed. In Experiment 1, we found that, relative to scrambled eyes, masked fearful eyes facilitate attentional orienting and delay attentional disengagement. In Experiment 2, we replicated this effect when comparing backward masked fearful to neutral eyes. Thus, the data suggest that nonconscious fearful eyes facilitate spatial attention through facilitated orienting and delayed disengagement.     

Attitudes Toward Professional Psychological Help Seeking in South Asian Students: Role of Stigma and Gender

This study examined (a) the roles of perceived and personal stigma on attitudes toward professional psychological help seeking and (b) the effects of these constructs across gender in South Asians. Personal stigma and being male was negatively associated with attitudes toward professional psychological help seeking; no difference in the association between personal and perceived stigma and attitudes across genders was found. These findings have implications for the engagement of South Asians in mental health services in the United States. Este estudio examinó (a) los roles de estigmas percibidos y personales en las actitudes hacia la búsqueda de ayuda psicológica profesional y (b) los efectos de estos constructos en indiviuos sudasiáticos según su sexo. El estigma personal y la identidad masculina se asociaron negativamente con las actitudes hacia la búsqueda de ayuda psicológica profesional; no se halló diferencia en la asociación entre estigmas personales y percibidos y las actitudes de los distintos sexos. Estos hallazgos tienen implicaciones para la participación de los individuos sudasiáticos en los servicios de salud mental en Estados Unidos.     

The wellness behavior interaction model

A cognitive-behavioral model for conceptualizing wellness is proposed consisting of situational/antecedent variables, person variables, and consequence variables which, taken individually or together, may serve to describe and explain wellness behavior. The model also is interactional in the sense that different categories of variables or factors within a category may impact on each other in a multidirectional fashion. A selective review of research relating to each variable is provided to demonstrate the need for such a multidimensional conceptual scheme for wellness.     

A ganglionic model of “learned helplessness”

The phenomenon known as “learned helplessness” (LH) is seen broadly across the animal kingdom. Some of the basic characteristics of this behavior are: failure to escape shock when it is possible to do so following non-escapable shock; reversion to non-escape behavior even after successful escape; if the animal is given escape/avoidance training prior to being given inescapable shocks, the latter will not interfere with its ability to later show normal escape/avoidance behavior (generally described as an immunization effect); following inescapable shock training the animals often become “passive and still” when confronted with an escapable shock. These behaviors are seen in intact mammals, lower vertebrates, and invertebrates. In fact, the basic characteristics are even seen in a spinal rat and, with the exception of one characteristic not yet examined, in an isolated thoracic ganglion of an insect. The brain is evidently not essential either in mammals or in invertebrates for demonstrating this behavior. Not only can an insect ganglion show the behavioral characteristics of LH, but the neural information underlying the phenomenon of LH can be shown to transfer from one ganglion innervating one pair of legs to another ganglion innervating a different pair of legs. Thus, how CNS information underlying LH is coded and transferred from one site to another within the CNS can be examined in such a system. The LH model has provided valuable insights into the physiology of depression. This model suggests that human depression is caused by one’s lack of control over traumatic events. It is supported by a number of parallels between depression and LH behavior. Tricyclic antidepressants, MAO inhibitors, and ECT, which are effective in treating depression, also can prevent and reverse LH in mammals. It would be important to find out if they are also effective in invertebrate models. The fact that the characteristics of the behavior called LH are seen in invertebrates such as slugs, cockroaches, and locusts provokes other intriguing questions about the presence of cognition at these phylogenetic levels, as well as what animal or preparation constitutes an appropriate model for human depression.

Worksite Stress Management with High-Risk Maintenance Workers: A Controlled Study

This study evaluated effects of a worksite stress management/health promotion program with primarily minority blue-collar employees showing a number of high-risk health behaviors. In a biopsychosocial approach, participants were assessed with a standardized health risk appraisal that included physical and behavioral variables, plus measures of self-control, health attitudes/satisfaction, and other factors. A controlled group design was employed with pretreatment, treatment, posttreatment, and three-month follow-up. Participants were randomly assigned to a wait-listed control group (n = 26) and a health promotion intervention group (n = 24). The latter received a multimodal intervention including stress management training, educational workshops and counseling, and a self-directed behavior change program. Following posttreatment assessment, the control subjects were given treatment and their data were then added to that of the initial treatment group to comprise a total group of treatment finishers (n = 33). The results revealed a number of significant differences between the two groups at posttreatment and/or for the treatment finishers across time (pretreatment vs. posttreatment and/or follow-up), including certain of the physical and behavioral measures, self-efficacy, and some health attitudes, but no effects for job-related measures, such as absenteeism and job satisfaction.     

Part and bipartial canonical correlation analysis

Extending the definitions of part and bipartial correlation to sets of variates, the notion of part and bipartial canonical correlation analysis are developed and illustrated.
