Rapid activation of the lexicon: a further investigation with behavioral and computational results

Priming effects were observed in a categorization task for both prime-target synonym pairs (e.g., boat-ship) and first-associate pairs (e.g., boat-sea). However, the amount and onset of priming were different for synonyms and associated pairs. The effect appeared sooner for synonyms (at prime duration of 43 ms) than for associated words (57 ms onset) but was present for both these relationships at 71 ms of prime presentation. A prime visibility pretest was conducted with the same participants in order to determine the rate of recognition of our prime words. Last, a French matrix of the HAL model was built, which showed that synonyms pairs were semantically closer than associated pairs. These results are in accordance with our previous study (Frenck-Mestre & Bueno, 1999) and are discussed in relation with semantic models, such as Plaut's (1995) distributed model.     

Suicide survivors' perceptions of the treating clinician

Seventy-one suicide survivors were surveyed about their perceptions of the clinicians who were treating their loved one at the time of death. Survivors provided information regarding their perceptions and attitudes toward clinician behaviors before and after the suicide and their perceptions of helpful and troubling aspects of clinician behaviors. Results indicated that survivors share a number of common opinions regarding the mental health care providers treating their loved ones. Several differences existed between survivors who consider lawsuits against mental health care providers versus those who do not. The implications of these findings for clinical practice, legal issues, surviving suicide, and future research are discussed.     

Marriage in the 20th century: A feminist perspective

A defining feature of the 20th century in Western civilization was a profound change in the roles women play in both private and public life. The field of couple therapy was influenced by that change and, to a limited extent, participated in it. I will argue that the field has avoided fully embracing the principles of feminism that generated the social changes in gender and marital roles, settling instead for a more token acknowledgment that gender means something, without wanting to specify what that something is. In responding to the other articles in this issue, I make the case that the connection between gender and power in marriage needs to be more fully integrated, in the theory, research, and treatment of couples.     

Amphetamine and morphine produce a conditioned taste and place preference in the house musk shrew (Suncus murinus)

Rats have been shown to avoid consuming a flavor, but prefer a location, previously paired with amphetamine or morphine. A series of 4 experiments evaluated the hedonic properties of amphetamine and morphine in the house musk shrew (Suncus murinus), an insectivore that (unlike rats) is capable of vomiting when exposed to toxins. Unlike rats, amphetamine (20 mg/kg) and morphine (20 mg/kg) produced both a conditioned sucrose (0.3 M) and saccharin (0.1%) preference in shrews (administered intraperitoneally), when measured by both a 1- and a 2-bottle test. At the same dose, both drugs also produced a place preference in shrews. These results suggest that the potential of rewarding drugs to produce taste avoidance may vary on the basis of the ability of the species to vomit.     

Research ethics for mental health science involving ethnic minority children and youths

In response to U.S. Public Health Service projects promoting attention to disparities in the outcomes of mental health treatments, in July 2001, the American Psychological Association, the National Institute of Mental Health, and the Fordham University Center for Ethics Education convened a group of national leaders in bioethics, multicultural research, and ethnic minority mental health to produce a living document to guide ethical decision making for mental health research involving ethnic minority children and youths. This report summarizes the key recommendations distilled from these discussions.     

Clinician race, situational attributions, and diagnoses of mood versus schizophrenia disorders

This research examined clinicians' consideration of situational factors in diagnostic decisions of mood vs. schizophrenia disorders among psychiatric inpatients from a low-income, African American community. Clinicians completed questionnaires describing their diagnostic decisions. Responses reflecting the usage of situational information were investigated. African American clinicians used situational information more than non-African American clinicians. However, this increased attention to situational information was not uniquely associated with a particular diagnostic decision for African American clinicians. In contrast, consideration of situational attributions by non-African American clinicians did increase the probability of a mood diagnosis. Logistic regression analyses suggested differential application of a diagnostic standard among African American and non-African American clinicians. Implications for enhancing the cultural sensitivity of diagnosis practices are discussed.     

Positive psychology progress: empirical validation of interventions

Positive psychology has flourished in the last 5 years. The authors review recent developments in the field, including books, meetings, courses, and conferences. They also discuss the newly created classification of character strengths and virtues, a positive complement to the various editions of the Diagnostic and Statistical Manual of Mental Disorders (e. g., American Psychiatric Association, 1994), and present some cross-cultural findings that suggest a surprising ubiquity of strengths and virtues. Finally, the authors focus on psychological interventions that increase individual happiness. In a 6-group, random-assignment, placebo-controlled Internet study, the authors tested 5 purported happiness interventions and 1 plausible control exercise. They found that 3 of the interventions lastingly increased happiness and decreased depressive symptoms. Positive interventions can supplement traditional interventions that relieve suffering and may someday be the practical legacy of positive psychology.     

Oculomotor consequences of abrupt object onsets and offsets: onsets dominate oculomotor capture

Previous research has shown that the appearance of an object (onset) and the disappearance of an object (offset) have the ability to influence the allocation of covert attention. To determine whether both onsets and offsets have the ability to influence eye movements, a series of experiments was conducted in which participants had to make goal-directed eye movements to a color singleton target in the presence of an irrelevant onset/offset. In accord with previous research, onsets had the ability to capture the eyes. The offset of an object demonstrated little or no ability to interrupt goal-directed eye movements to the target. Two experiments in which the effects of onsets and offsets on covert attention were examined suggest that offsets do not capture the eyes, because they have a lesser ability to capture covert attention than do onsets. A number of other studies that have shown strong effects of offsets on attention have used offsets that were uncorrelated with target position (i.e., nonpredictive), whereas we used onsets and offsets that never served as targets (i.e., antipredictive). The present results are consistent with a new-object theory of attentional capture in which onsets receive attentional priority over other types of changes in the visual environment.     

Explaining disproportionately high rates of adverse birth outcomes among African Americans: the impact of stress, racism, and related factors in pregnancy

Compared with European Americans, African American infants experience disproportionately high rates of low birth weight and preterm delivery and are more than twice as likely to die during their 1st year of life. The authors examine 5 explanations for these differences in rates of adverse birth outcomes: (a) ethnic differences in health behaviors and socioeconomic status; (b) higher levels of stress in African American women; (c) greater susceptibility to stress in African Americans; (d) the impact of racism acting either as a contributor to stress or as a factor that exacerbates stress effects; and (e) ethnic differences in stress-related neuroendocrine, vascular, and immunological processes. The review of literature indicates that each explanation has some merit, although none is sufficient to explain ethnic disparities in adverse birth outcomes. There is a lack of studies examining the impact of such factors jointly and interactively. Recommendations and cautions for future research are offered.
